Toyota Sienna Change Vehicle

"Right front wheel needed replacement. Perhaps related to the replacement of the ball joint"

"regularly addressing alignment problems. hugely inconvenient somewhat costly"

"Since purchase, can't be perfectly aligned. Wears out tires quickly. Problem with all 2004 AWD Sienna's. There are websites describing the issue"

"Had to relate due to noise"

"With nearly 200,000 miles, the ball joints were worn out."

"I had a bolt shear off that had to be replaced"

"Ball joints became loose necessitating a replacement"

"Ball joint needed replacement"

"Droparm bushings wore out. Very expensive repair."

"Worn control arm bushings requring $1700 replacement"

"Bushings separated and needed to be replaced"

"Took van to dealer concerning tire wear. Dealer set up time for front end alignment after I told them it had already been checked and iwas within specs. Dealer said they were 99% sure that was the problem. An hour and a half after front end check dealership said it was within specs and they did not know what was causing tires to wear on the outside edges only! Independant garage found the problem,bad bearing"

"the issue of bushings was part and parcel of the front end struts and shocks issue."

"When the struts/shocks were replaced, they also replaced the tie rods and bushings. That was about a year ago. Recently the car felt like it was wobbling when I would hit 40mph. My mechanic showed me the bushings in the tie rods and pointed out that they were worn so they were under warranty and they replaced them."

"Bushings in control arm were cracked and had to be replaced"

"Bushings in lower control A arms were broken"

"bad bushing on control arm needed to be replaced"

"I was told that the bushings were wearing down but I did not have them replaced yet. I was told that could be another problem that might cause the vibration"

"Right lower control arm replaced and now needs the other side to be replaced"

"Lower control arm bushings keep failing. Third time replaced"

"Bushings were worn on the front lower control arms. This caused some play in the steering as well as a small jolt when applying the brakes. Also a loud clunking sound when going up over a curb (as in to a driveway)"

"Part of the tiecrod"

"Rear bushings had worn out, allowing the axel to bounce. Causes tire wear"

"Front lower control arm bushings were separated - replaced both for cost of $1350."

"the car had the problem immediately, when turning.my ind garage did research to find & repair. Toyota gave me a $500 repair credit. Dealer was useless"

"Power steering fluid was leaking. Replaced power steering return line"

"Currently a small leak that requires fluid be added about monthly. Problem will continue to worsen and is leaking into the boots and will require repair within the year"

"Dealer asking $1500 to replace steering rack"

"Rack and pinion needs to be replaced as power steering fluid is leaking. Dealership said that the design of the system means that the whole thing must be replaced (including things that are working fine) and can not be repaired and that the cost will be several hundred dollars. Poor design"

"Had issue with occasionally losing power steering when turning. Leak found which required replacing complete rack & pinion"

"Power steering fluid was leaking. Replaced power steering rack for $1,393."

"Major overhall on steering system"

"Leak in the hydraulic fluid required replacing the internal steering column unit"

"Steering column was leaking fluid and had to be replaced"

"Had a power steering fluid leak. The dealer advised that the steering rack needed to be replaced. Total cost of job was about $1200"

"The dealer wants $1,200 to fix a leak; I'll just add fluid when it needs it. It will be a lot cheaper"

"same as above"

"Very slight drip out of the passenger side of the hydraulic actuator for the power steering"

"power steering box replaced"

"There was a humming noise when the engine was running (in gear or in park). Palms to Pines (Palm Desert) diagnosed a power steering pump failing. Replaced the pump, flushed the system, and replaced with new fluid. No more humming nosie."

"Steering intermittently became hard to turn wheel. Pump worn out and replaced"

"MAKING NOISE WHEN THE TEMP. IS LOW."

"Fluid not completely replaced when front end reassembled. Pump made a noise when car was turning. I replaced the fluid and problem ceased"

"Leaking power steering hoses. Replaced"

"jittery steering caused by struts, power steering pump and belts and tires. 100,000 to 120,000 miles"

"Replaced expensive power steering pump and connecting parts"

"Front struts broke, needed full front struts/springs/shocks replaced."

"The front struts were worn out and needed to be replaced. The steering would groan and creak when you turned the wheels."

"Had to replace both front and back at about 140000"

"Replaced front struts $1,000"

"The struts had never been replaced. My Sienna is 13 years old and has over 200,000 miles on it. It was due time for those struts to be replaced. When they replaced the struts, they also replaced all the adjoining parts. I would say that the struts were well overdue for replacement and I would call this more a maintenance issue than a failure in product"

"Struts failed prematurely and are noisy"

"It took repair place a couple of times to fix the problem-Not Toyota dealers problem"

"needed new struts"

"this problem happened at about 250000 too. relpairs run about 1000 Cdn. No failures just symptoms resulting in diagnosis of ware. very high level of confidence in this vbehicle"

"The mechanicals holding the body off the axle of the left front wheel had failed and was minimally supported. The repair shop replaced. The coil spring had broken. The car repair shop replaced the suspension/struts/shock/springs on both front side wheels to keep the wear on the tires even--and to prevent the same problem happening on the other side. The cost of repair for both sides was $1100."

"Struts went on the front and I replaced them, job was long due to proximity to windscreen and firewall."

"Drivers side of car showed oil on the ground. Took to repair shop and was diagnosed with a leaking front strut. I replace both to be on safe side."

"• shocks were old and needed to be replaced"

"Struts wore out. First attempt to replace at Sears was a mistake as the tech did not know enough about this vehicle. Had to get repaired properly at dealership"

"Rear shocks replaced"

"Front struts and rear shocks needed replacing. This cost $1200"

"Needed to have the whole front end replaced. ADDITIONAL DIFFICULTY not listed has been the automatic doors. Side door gets stuck/freezes and rear latch is not automatic"

"premature wear out"

"Front struts were leaking hydraulic fluid. Both were replaced and other parts replaced. Ride improved greatly"

"Leaking rear shocks"

"Front shocks and struts needed replacement. Not unreasonable given the mileage and age of vehicle"

"Rumble noise over pot holes"

"Leaking shock that required replacement of the shock/strut"

"Shocks/struts are coming up on each inspection when get oil at Toyota. After rack/pinion just completed wondering why not noted back then"

"The bushings on the rear shocks failed. Toyota unable to diagnose and instead said the bushings on the axle had to be replace ($1000.+). Went to Pep Boys and they diagnosed that a bushing on the shocks needed to be replace. Got new shocks ($215) and"

"Strut needs replacement and due to age of car, it will be difficult because it is rusted. Planning to buy new car instead of making this repair"

"All 4 were worn out and had to be replaced"

"The front left shock leaked and no longer worked. It had to be replaced along with the front right"

"Morew and more difficult turning"

"Original rear shocks/struts replaced. Front control arm and bushings replaced"

"shocks needed to be replaced"

"Front struts and rear shocks were worn out after 180,000 miles. Kept scraping the hitch because the back was so worn out"

"Rrear coil spring broke"

"broken rear spring"

"One torsion bar was broken and the other one was about to fail."

"broken rear spring"

"My front right spring broke. I had replaced the struts once before but re-used the original springs. I ended up replacing the struts and springs both since it had been 75,000 miles since I had done the struts"

"Please see comments for shocks and struts. They all failed together. The left-front spring had cracked/broke, and the van's body was essentially resting on the axle."

"I was told a spring was broken several weeks ago, but I have yet to fix it. I'm not really sure it's contributing much to a worse drive experience or a safety issue. I'm planning to get a new or newish vehicle soon."

"The left front spring was broken."

"Broken rear springs"

"The spring on the passenger side broke"

"Broken right rear spring. Was not a noticeable drive-ability issue"

"front driver's side spring broke and the top bracket rusted out. Needed complete replacement. Mechanic replaced front shocks at the same time"

"Needed repairs because of poor condition of the roads after last winter"

"The springs were sagging so we scrapped the bumper a lot and the car swayed so bad that it made you sick to your stomach when sitting in the rear of the van. Cost to replace two rear springs $800"

"torsion bar bushing replaced"

"Another recurring problem with this model/year. LOTS of noise/clanking in the front end. Have had all steering linkage components replaced which helped some but there are still noises that the technicians cannot identify."

"Steering rack and lower control arm had to be replaced because the amount of play in the steering rack and suspension was causing the vehicles stability control to randomly brake one of the front wheels while driving at highway speeds and in a mild curve."

"The auto developed vibrations and clicking noises when brakes were applied. The upper control arm bushings were badly worn. Cost nearly $1000 to replace them. While at it, except for 2 occurrences when the air went out, and a few other minor items, we had no problems with this vehicle until about 2 years ago"

"Right front bushings were worn completely through and required replacement"

"Steering wheel would pull left when brakes applied. Car would continue to drive straight if the driver let the steering wheel jerk right when brakes applied. If steering wheel held firmly, the car would jerk right slightly"

"I was informed by my mechanic that the rack and pinion was worn and should be replaced"

"had to be replaced"

"The Steering U-Joint on the engine side of the firewall deteriorated so the steering was stiff when turning at one point and also the steering column would rattle"

"Front end of van tended to move left to right going down the road. Dealership said it needed a complete front rack but could not tell me why !"

"Replacement was needed due to an internal leak. Age is taking its toll."

"Air conditioner dripped water directly onto the main front end of the car holding the steering / engine. Over time it cause the frame to completely rust. We had to spend over $2k to have a used frame installed. All because Toyota didn't route the water condensation away from the frame. Stupid design."

"Rack and pinion seal leaking."

"intermediate steering shaft needed replacement"

"Steering gets very stiff in cold weather and sometimes locks up in the beginning of drive"

"Rack and pinion developed leak that required replacing"

"The toyota technicians when doing a front end alignment over tighten the adjustment bolts thus stripping them for the next alignment, consequently the parts hve to be replaced costing $425.00"

"Had to replace the rack and pinion"

"Same issue"

"The rack & pinion was replaced since the tie rods couldn't be freed so all had to be replaced. Had to do an alignment after"

"Control rods/bushings need replacing. Steering is currently a bit "soft" and bumps cause excessive vibration"

"Rack and Pinion wearout seemed to be a lot sooner than the previous Dodge Mini we had. Steer fluid leaks and wear/tear on the tires even though bal-n-aligned regularly. After services completed, tires and leaks seem to be under control. Tires may ha"

"steering shaft has to be replaced"

"Rack & Pinion leak, drive shaft replaced due water penetration. steering make noise when turning"

"Linkage and steering column leaking"

"The universal joint in the steering column rusted and seized up. I have never had rthis hapopen before in any car. The steering column had to be replaced"

"Diagnosed by Dealership. Preventative replacement of parts"

"The steering shaft wore out on my Sienna. I took it to a private mechanic shop I trust and they told me it was a common failure on Toyota Siennas. They replace the steering shaft for me and it has been fine since"

"I replaced steering rack due to leaking in passenger side of rack"

"The steering had what I would call a flat spot in which the steering felt disconnected from the wheels. It was repaired this year but was very expensive"

"I was told by the dealership that the rack and pinion needed to be replaced so I had them do it"

"It has had alignment problems for quite some time. I've had it aligned 3 times but but the problem persists."

"There was to muck vibration when braking to stop."

"I believe the lower control arm needed to be replaced. Whatever it was, it's usually an easy/cheap fix on most vans. The Sienna required an engine mount to be loosened and the engine jacked up which equals expensive repair"

"While driving my steering wheel will vibrate from just mildly to a really bad vibration that I feel I have to really hold on tight. I have had new tires put on and also had them rotated. It seems to help for a while but then starts again. I have also"

"Ever since we purchase, never been able to get steering properly aligned. Caused uneven tire wear. Tire replacement every two years. Toyota hasn't been able to figure out. Causes vibrating steering wheel"

"Vibrations of front passenger side wheel at speeds approaching 70 mph"

"When turning steering wheel the car would wobble"

"Tie Rods are going. Have put a lot of miles on this car. Have to hand it to Toyota that their cars last. But more costly repairs do come with age"

"One tie rod had to be replaced due to wear"

"The tire alignment is a result of the trying to fix it but it continues. It is something as I mentioned earlier."

"Wheel and axle bearing went out as did both fron struts and mounts"

"• uneven tire wear caused by faulty shock absorbers"

"constantly have to address wheel balance. nothing seems to fix it long term"

"From my little knowledge of this vehicle only what has had to be repaired or replaced. Starting to cost too much to keep up with. All records of this cars repair are with Larry Miller of Peoria. My service representative keeps me aware of what should be done to this Toyota. It has never had service anywhere else, except Firestone for lifetime balancing"

"Bearing was causing noise and vibration, had it replaced and every thing is working well."

"They caused uneven wear requiring almost new tire be replaced"

"Wheel bearings on front driver's side needed replacement twice in one year (second was covered by warranty)"

"Replaced both front bearings. First about 164000 and second about 177000"

"Wheel bearings had to be replaced because they were sealed and couldn't be lubricated. Also had to replace the hub due to wear by the wheel bearing race"

"They wore out and it was an expensive repair. It also led to us having to replace the tires, which was not pointed out to us by the service people at the dealership"

"Noticed a loud noise from the rear of the car. Dealer said the wheel bearings were deteriorating; we opted not to replace due to cost and dealer said it did not affect safety"

"Had to replace both front left and right bearings- pressed on bearings created a big expense!"

"bearings needed to be replaced"

"Wheel bearing on front driver's side wheel failed, which wore down the wheel hub and both had to be replaced. Passenger side front wheel seems to have the same problem"

"Driver side sliding door fails to fully close due to faulty rear slide assembly. Passenger side sliding door motor failed, was cheaper to remove motor and cables than to fix."

"Automatic door drive cable frayed causing door to operate slowly."

"Both rear slider doors had trouble opening and closing. The drive motor cabling and plastic pulley assembly was the problem in both doors. Dealership wanted nearly $3000 per door to replace the the faulty parts. The cost was prohibitive on an older vehicle so I disabled the motor and operate the doors manually. I have since learned this is a common problem on Toyota slider doors."

"The passenger side sliding door started making a grinding noise. Googling indicated the cable was wearing out. And it would be expensive to fix."

"Won't open, power door failed or had to be pulled open and closed."

"Electronic sliding door's cable snapped and dealer wanted $3200 to replace it."

"Two problems with doors: First, when the minivan was about 4 years old in 2008, the sliding door on the passenger side came off track, more than once. One time, we could not close it and had to drive to the dealer with the door open. The kids were in the car and I made sure they were securely seatbelted in the 3rd row. In 2016, the second problem happened. The hinge on the driver's door broke. So that door just swings freely when you open it. Very hazardous to anything parked on your left. I tried to get it repaired and everyone wanted thousands of dollars and one repair shop would not even touch it."

"Driver's side door closure failed. I purchased a replacement, had the door welded and replaced the closure. Toyota would not help"

"Power sliding door drive cable broke"

"Driver's door was making loud noises when it was opened or shut. Something was loose inside the door. The door was repaired on a Toyota Recall about 6-7 years ago. It worked fine for about 6 years, then broke again.....same noises. This time, no company repair. To me this sounds like a design deficiency"

"driver front door check - steel and weld cracking / coming un welded - squeak / clunk sound and poor door function when opening / closing"

"loud popping noise. The mount for the door thingy that keeps the door from opening too far came off its hinge inside the door. Some welding needed to be done"

"Cable on sliding door broke. We were just "out of recall" zone. Cost over $1000 to repair. This apparently was a known defect"

"Latch on sliding door broke off of door frame on 2 of the three screws, and third screw fell off. Subsequently third screw tore through the frame as well. Presently holding on with washers, require frequent tightening"

"Driver's side door, door check arm broke where it's attached to the door (not the frame)"

"Driver's side door had wear and tear from so many years of use (noise, broken hinge). Had Body Shop repair for $575"

"driver side door hinge broke"

"Drivers door check pocket failed Right power sliding door failed This is the last Toyota I'll ever buy"

"Sliding side door does not completely close"

"Driver side front door check pocket is broken and makes popping noise during opening/closing. Dealer indicates a new door replacement is required and that would cost $2000+"

"The driver side door has a design defect common in Sienna. The hold open device breaks out causing problems with the window operating and the door swinging too wide. Toyota's estimate to repair was a new door at $1800. If this was a wear and tear issue, I wouldn't be too upset, however, it is a design defect which they would provide assistance for a limited number of years. I don't know if the issue has been resolved in newer madels but it prompted me to choose Honda for the new vehicle"

"Both sliding doors failed, less than a month apart. $3500 to replace cables and motors"

"the back door comes down with out warming, when the van was new they cloud not find what was wound. But now that i have over 100000 miles they can fix it for $589.00. now hows that for customer service"

"Passenger automatic sliding door mechanism broke. Fixing it would cost $1,500. We have been manually opening/closing it but this is too difficult (heavy/hard) for children under 10years old and is embarrassing, but fixing it would cost too much. Drivers side automatic sliding door works fine"

"Drivers side door hinge is broken. I've had it repaired by a body shop 2 times, and it has broken again. I now live with a loud click whenever I open or close the drivers side door."

"the drivers door check caused the door metal to fatigue and crack and the welds to begin to fail, and Toyota did nothing about it - the issue seemed like a rudimentary design flaw that has apparently plagued many Toyota sienna cars. The door had to be removed and repaired, on two separate occasions, at great inconvenience and expense. very bad of Toyota!"

"The power passenger door failed twice, and after replacing the motor once, we just lived with it as a powerless door. Also, the front passenger door fell apart -- the plastic detached from the metal door."

"Power sliding door will no longer operate. Problem is related to bag hinge and cable. Would cost $3,000+ to repair. Not worth it."

"Driver's side power sliding door failed due to cable/clutch/motor failure inside door. Cost $1530.28 to repair."

"automatic sliding door will not open"

"Driver's door closure mechanism became loose, weld broke. I put a bolt through it, now fine"

"Door hinge has became broken. The hinge has to be welded back on"

"Driver side door, hinge mechanism that controls opening and closing, not the regular support hinges, is in the process of breaking. Entire door will need to be replaced"

"Door stop on driver side door makes aloud crack when door is opened. Toyota says only permanent repair is to replace the door"

"Toyota issued a warranty return on door issues, dealer would not honor because I am not the original owner"

"Thank God I bought the extended warranty. My power door motor has died twice. The drivers door window didn't work and the door check need to be replace after I had it fixed two times. The door check was a known problem on many of the vans. Toyota"

"Both automatic doors failed parts alone were1600 per door"

"Power sliding door no longer opens or closes when activated via button or remote. Must be activated by pulling on door handle"

"doors easily caught by wind and flung open beyond where the door should stop. Very expensive to have fixed because the whold apparatus needed to be replaced by a body shop. The second time we didn't bother to fix it"

"power door stopped working. Cable rusted out"

"Side doors stopped operating. The estimate for repair was astronomical (approx $2K). I disassembled the door and fixed it myself. Periodically it requires revisiting the problem and correcting it again (approx every 6 - 8 months)"

"Door assembly has been repaired twice (over 5 years) due to a loud popping noise when opening or closing the driver side door. Noise may be starting to come back"

"Motorized closer failed on passenger's side rear door"

"Cable snapped in driver's side power sliding rear door. Very expensive to fix so have not fixed it"

"Driver's side front door hinge is snapping and dealer has told us weld is loose"

"the car is a dump but I have so much invested in repairs it should be like a new car and can't afford to get a new one"

"sliding doors freeze in cold temps"

"Right sliding door has had several problems with the hinges and cables, some covered by warranty enhancement"

"power sliding door stopped working. Took it to dealer. Dealer repaired ($1000). Broke again less than a year later. Same issue"

"Power door cable broke one month after the (unannounced) warranty extension expired. There was no inspection done by the dealer, which would have discovered the wear before it broke. The repair cost is ridiculously expensive for what amounts to repla"

"Front door hinges "snapped" and is a very costly fix. Apparently it was acknowledged by Toyota but never recalled. Also, the sliding doors freeze shut and can't be opened until thawed!"

"Cable system on both powered sliding doors snapped...too expensive to repair"

"Door making popping noise when opened. Dealer said requires body shop to fix at $375. Occurred at 101,000 miles , just out of warranty"

"Broken weld on overtravel spring"

"Driver's door frame failed where the latch attaches"

"Power sliding doors freeze shut"

"driver side door check failure"

"sliding doors frozen shut when cold"

"2004-2006 Sienna's have a design weakness in the front driver and passenger side door checks being spot welded. Our driver side door check became unattached and Toyota claimed it wasn't under warranty and told us that we needed to buy a new door for"

"Electrical sliding door is inoperative. Does work manually"

"Driver's door swings open wildly without stops until it reaches the end of it's hinge travel"

"There is a known issue where the metal cup inside the front door where the hinge attaches will crack. So the sound is the metal flexing and popping due to the crack. The solution is a new door or welding it to repair it"

"slow or stopping in cold weather"

"The electric sliding door stopped working and cannot be opened"

"The door stop/detent inside the driver's door cracked then broke, so the door does not stay open on the detent anymore. Also, since the detent broke the driver's side window cannot be opened all the way due to broken metal jamming the window"

"Popping when driver side front door is opened or closed. Dealer wanted $1700 to repair. Otherwise, it has been a very good auto"

"doors do open or close easily"

"Broken cable sliding door"

"Driver door part that limits how far door opens is broken. Dealer says they can't fix; must take it to a body shop!"

"The passenger side motorized sliding door had its wire rope fail. Repair parts are only available as a full assembly that with installation would cost over $750. The electric lock on the driver side slider no longer works"

"Rear passenger power door has failed at interval for several years and reported timely to several dealers. Last week failed and could not close door. Toyota flatly refused any help or to stand behind an obvious poorly designed power door. Now inde"

"Sliding doors actuators on BOTH sliders died. Had the 2004 Sienna driver's door clicking, then broken weld. No support from Toyota, well documented, common problem"

"Some kind of design flaw relating to the interior cable that releases and pulls back the door. The cable frays, jams and fails. Toyota extended the warranty on this for a number of years but we were outside the time period. Toyota paid most of cost"

"The power sliding door broke a small piece of plastic. which cannot be repaired unless the entire operating mechanism is replaced for $1800 dollars. so I am living without a power door"

"The drivers door weld broke and the passanger sliding door quit working"

"Power sliding door failed to close. This is the third time that this door has failed. Estimated cost to repair was $3000.00 Conversion to manual operation including custom fabrication of essential parts at a non dealer independent repair shop was $3"

"The sliding doors are supposed to open with a button, but they have both failed. The main one on the passenger side (which is the safest for children to enter) failed mechanically and will cost over $1300 to fix. The other one will not open because"

"power door failed to operate electrically"

"This van has electric sliding rear passenger doors. The doors became sluggish whether using the electronic button or using the handle. Then the doors quit working at all. Dealer fix was very expensive. Used parts instalaled"

"The driver side heater no longer works"

"Passenger heated seat does not heat"

"seat heater does not work. been told to buy brand new seat for $1600"

"The cable in tailgate latch broke suddenly, making the latch inoperable (unable to open tailgate until repaired). The two rear sliding doors of this vehicle had similar failures over the years. This was definitely the weak point of this model. I have had no other mechanical problems with this vehicle other than routine wearout (brakes, etc.)"

"Florida heat destroys the master control switches on the driver's side. Dashboard completely craked up. Was unable to have it replaced. difficult to operate window open close function"

"front passenger door swing limit bar broke"

"The passenger door cannot be opened from the inside. The latches on both sliding doors of the van have been fixed because of recall and still malfunction sporatically"

"Sliding door lock solenoid stopped working, had to manually lock the door"

"The drivers side door latch developed a clicking hitch. Very annoying so we had a body shop replace and do some welding"

"door check noise"

"rear door handles broke off. rear door locks failed. $400 Each"

"Latches for the 3rd row seats are not functioning properly. They do not release the seats when the strap is pulled to fold the seats. Also the 60% seat back does not latch open"

"The weld broke for the drivers side door and there was not covered"

"The door to the gas tank was being shut gently one day, and it fell off in my hand because the metal just suddenly gave out"

"Rear sliding door lock fails to respond to electrical control at driver's station"

"Some of the seat belt receptors have worn, requiring extra force to fasten the seat belt. Toyota issued a recall for this problem, and we took our minivan to a dealer to have the problem fixed, but they had to order parts, and we never received a call saying the parts had been received."

"Seat belts in this vehicle have a tendency to "fold over" when pulling them out, then they jam. Apparently it is a bad design in the retractor or guide system"

"seat belts fold over during retraction and it is very hard to unfold them."

"The driver's side retractor failed and the cost to replace was significant"

"Both front seat belts twist constantly & I need to return car to dealer to have them untwisted-this is a known problem w/my Sienna, I think Toyota should fix this as a recall"

"Passenger seat belts stick and do not recoil"

"The seat belts in the front and middle passenger side seats sometime do not retract correctly"

"If shoulder belt strap on driver's seat is pulled out quickly it often doubles over and gets jammed in the guide attached to the frame. This can be very hard to undo. This is a safety issue I reported to Toyota and NHTSA in the past to no avail"

"The front passenger seat belt does not retract and pull out each time"

"Seat belts regularly get stuck and cannot either be pulled out or retract. The repair often is to remove door trim to expose the mechanism and to move the reel until it goes on its own. Some of the failures are due to the seat belt being twisted,"

"Gear in the seat base has broken. Toyota wants 2000$ to fix . Mechanic set seat to fit me. we dont move it any more"

"Broken gear. $2000 to fix. Didn't fix. taped over the controls so seat does not move forward or reverse."

"Electric seat control stopped working. To repair myself is eighteen hundred dollars. too pricey, no easy fix,"

"Cannot extract one of the rear seats"

"Started erratic movement, at times will not move. Can not buy bad gear to fix, have to buy complete movement assembly to fix, $1850 for assembly. Plus labor $400 to $500"

"Electric positioners on driver's side were always irregular, despite several service visits"

"After about 6 years of ownership, the seat heaters stopped working. Have not had this repaired because of cost"

"Rock off of bridge broke sunroof. Insurance fixed. We hardly ever use but then wanted to open it and cables broken or off track $1500 to fix - so we did not"

"A drain pipe from the sunroof area plugs (for the second time in 3 years) causing water to drip into the car interior"

"Known defect with the Sienna."

"Pressurized gas struts which hold up rear hatch when opened failed. As it turns out, only one failed. Vehicle has an automatic opener, and hatch would get most of the way up, then start closing. This was frightening and a bit dangerous. Replacement struts were not expensive and were easy for me to install myself. Aside from needing to prop the hatch open, they are not a lot more difficult to install than windshield wipers on some vehicles."

"Shocks on trunk door became worn out, so that the trunk would not stay up. Replaced shocks, and now works"

"tailgate does not automatically lower and when dealer looked at they said was not covered under recall but replaced door strut."

"The "pistons" stopped working that could keep the hatch open. Both had to be replaced"

"Recall last summer for spare tire cable. Toyota still doesn't have a fix, so spare tire sits inside my minivan (taking up space) rather than underneath it"

"Auto tailgate failed multiple times"

"Rear central hatch door to the minivan won't reliably go up and down any more"

"Does not stay up when open"

"Driver side window fails to go down fully; sticks halfway down."

"Glass mounting for both rear power vent windows failed separately, but within ten months of each other. Vent window is attached to the body at the front edge and the motor assembly that cracks the window open is attached to the rear of the window, which pivots open and closed. The front edge glass body mounting failed (glue/bracket) so that the glass was hanging loose only from the rear motor arm. First failure resulting damage to motor assembly, which needed to be replaced. Second failure resulted in window falling off the car completely requiring a new window. Total repair cost ~$1600."

"passenger side electric window is slow and noisy but the repair cost is $700 so I live with it"

"Rubber seal material around rear passenger window came loose. Repair required ordering parts and took 3 days"

"Compressor leaks and needs to be replaced."

"Compressor stopped working and and had to be replaced."

"Rear air stopped working. Due to age of car to expensive to have repaired."

"Car takes forever to cool down"

"Had to have A/C replaced"

"Blown relay caused compressor to cycle on and off reducing the cooling. had it replaced and system works well"

"Failure of A/C compressor and condenser"

"Electrical interlocks on the compressor has made intermitant failure of the A/C to start up. Still looking for a cure"

"AC compressore relay went bad. Low cost to replace $150"

"The A/C stopped producing cold air and The compressor needed to be replaced"

"compressor died after about 130,000 miles. replaced"

"A/C stopped working. Toyota dealer repair shop replaced compressor. Still didn't work. I suspect there was nothing wrong with the compressor, just that the control panel wiring was faulty. When they fixed that, A/C worked. Still out $600 for compressor replacement though"

"When I dropped my vehicle off at the dealership for routine maintenance, they called and informed me that the AC compressor clutch just fell off when the technician lifted the car"

"Compressor clutch stopped working"

"The compressor was worn out after so many years in the Arizona heat."

"The Relay on the compressor is old and faulty this causes the compressor to kick off under high strain. rather than replace the part i will rap it several times to allow it to connect."

"Compressor failed and had leak in condenser coil"

"My wife heard a loud noise from under the hood. The A/C was already weak, and so I had it looked at by the dealer. They found nothing. I tried to recharge the system, but it would not take the freon. I took it back to the dealer and told them something was wrong with the A/C. The dealer wanted about $1500 to replace the complete system (said that debris was in the system). I had the compressor replaced and system flushed with aftermarket with 5 yr warranty for $800."

"This was the second compressor that has had to be replaced."

"Leak led to loss of refrigerant which led to compressor burning out"

"Had to replace, don't think that is unusual for 130,000 miles"

"The compressor seized for the 3rd time. The first 2 times the dealer repaired (once under warranty). The dealer only replaced the compressor. The last failure our local shop replaced the condenser and evaporators to ensure the system was clean"

"compressor broke down, needed replacement"

"failed"

"Stopped working. Needs replaced"

"Stopped working. This the second Sienna that I have had the same problem"

"A/C quit cooling because compressor would not engage, compressor was replaced"

"Leeks needed to be replaced"

"The A/C unit went out"

"wouldn't blow cold air"

"AC clutch seized and ruined the compressor. We just sold our newer BMW and buying another new Sienna"

"A/C compressor stopped working and had to be replaced"

"The A/C Failed and the compressor needed to be replaced"

"We had it fixed"

"HVAC blend motors tend to cause problems. Replacement parts are extremely expensive. I was able to repair one myself, by disassembling it, and cleaning and lubricating the mechanism, but had to fabricate a way to hold part of it back together, as it is not designed to be serviced. Our independent Toyota service shop says this is a common problem."

"the blend door actuator motor went out"

"erratic, intermittent temperature control problems. Temperature controls don't work - heater only on, regardless of temperature knob setting or AC only on, regardless of temperature knob setting. Brought in for repairs but "it never acted up." Sigh"

"Servo that blends hot and cold air not working on passenger side. Always blows cold air regardless of setting. Dealer has been anable to get new servo for over five months. Dealer keeps telling me that it is on back order"

"Never worked priperly from "day 1""

"The AC stopped working in February 2017. When the car was in the shop for brake pad replacement, the mechanic noticed radiator leak and repaired it. After the radiator repair, the AC started to work. It appeared the automatic climate control was linked to the radiator function"

"temperature control not working properly"

"Never worked properly since the day I bought the car.No dealer could fix it."

"A/C for rear passenger compartment stopped working"

"AC cools well most of the time but won't periodically. Refrigerant was checked - ok - but dashboard switches do not work every once in a while"

"The Auto climate control kicks in when not turned on and changes setting of the mode and when blowing at upper vent or lower vent"

"Automatic Climate Control makes noises constantly- unable to adjust air flow control- has been fixed before"

"Rear climate controls has its own console dial, but has never operated properly"

"System open to access by rodents. Allowed rodent to get into blower fan and destroyed blower motor. 600.00 to replace."

"Rear blower unit turns on even when the switch in front is off. I have to turn the switch on and then off to get it to stop, and then it usually turns on again at unpredictable intervals after that."

"Periodically turns on in the rear of the vehicle without prompting. It's just an annoyance is all"

"The front AC/heater blower motor makes horrible noise at times. Brought in for repairs - $500 to replace even though it is EASY to get to and replace. Cost of new blower $350 plus labor"

"Not working"

"Replaced condenser with compressor as recommended by mechanic."

"To replace the radiator (which was leaking), the mechanic needed to remove the condenser. He could not disconnect the connections on the condenser without damaging the condenser, so we had to replace the condenser."

"Over the years I noticed the A/C wouldn't blow as cold as it normally would. I would get it recharged about once a year and that seemed to do the trick, but the interesting part was that it wasn't very low on the stuff that makes the A/C cold. Then last summer 2017, the A/C just stopped working. My mechanic found that the compressor died and needed to be replaced. Considering that the compressor was original to the car, I guess it had a long life."

"Rear air conditioner no longer cools. Always puts out hot air if rear blower is on"

"The condenser and evaporator were replaced by an independent shop to ensure all compressor parts were removed from the system ($3200) . The dealer would not cover replacement under warranty. I feel this is why we had the 2nd and 3rd failures"

"The system would stop cooling after the engine warmed up. I was told the condenser was failing and needed to be replaced, which it was and has worked well since"

"damaged from debris from failed compressor"

"connected with a/c"

"Front condenser failed and was not worth the expense to replace"

"AC would provide cool air for about five minutes then stop cooling. Car was taken to a Toyota dealer who replaced the relay. After repair AC works fine"

"This is the same problem I just discussed where the dashboard switches will not operate the AC every once in a while"

"Magnetic clutch relay had to be replaced"

"The keyless remote lost ability to unlock & open/close liftgate. Toyota traced problem to faulty wire running from fwd Body ECU to rear Power Back Dpor ECU. Toyota replaced wire. Wire installation error probably made by IMS"

"A/C relay failed at 77,600 miles and required replacement. Refrigerant was also replaced and system serviced"

"Air Conditioner quit, taken to a Lexus/Toyota specialist. He was able to repair the AC and radio both were electrical issues"

"Heated seats work on drivers seat, but not the passengers."

"There is no heat blowing from the driver's side, while warm air is blowing in the passenger. Also, strange noise in heating unit."

"heater occasionally stops heating. occurred and fixed in 2017, and agin in 2019"

"We had taken the van to the dealer to have 2 different recalls corrected. One involved replacing the Dashboard, FLA residents were supposed to get a different dash due to the weather and heat. After replacing the dash there was an issue, that some dash items no longer worked and the dash was marred, (not new looking). After a second try at fixing it the drivers side had air conditioning blowing out of the vents while the passenger had heat. They said that a controller had overloaded and failed,"

"Rear heat system failure. Replaced heater core. Still only heating on driver side. Air diverters in ax system not working correctly. Replacing car soon"

"Small leak developed in the heater caused glycol to evaporate and deposit as a greasy film on the inside windshield. It was too expensive to pull and replace heater. We have used a liquid stop to plug up the hole. Then we flushed the rad to get rid of any remaining leak stop fluid. So far this repair has worked"

"When starting up there was a clicking from the rear AC that lasted about 30 seconds. This ocurred each time I turned the ignition switch on. The Dealer diagnosed the problem at a cost of $50.00 that the entire rear AC unit needed replacing because th"

"Driver's side heat does not blow hot unless temperature is set to full hot"

"The heating system is very weak. On very cold days, it did very little to heat up the vehicle"

"Doesn't fully heat if getting air from outside"

"heating and AC system is intermittent in operation. the problem if with the 'doors' that decide where the air blown into the cabin comes from. Unfortunately, to diagnose/repair involves removing entire dash. (i.e. $1.5-2K)"

"It will not blow hot air in the back of the van. Cost to repair $1000"

"The leak was too small to be detected, but coolant level was down to 25%. Only a recharge was done. The air conditioning is still cold a month later."

"Issue began with the the A/C only working while the engine revs were over 2000 rpms Eventually the issue expanded to the van overheating when it was idling"

"There wasn't actually any leaks.The loss of refrigerant was very slow and occurred since the car was bought in 2003 ! Normal wear and tear-not a defect."

"A/C was not cold enough - took car to my mechanic who checked the system and added coolant. works fine now...."

"Ever since we bought the Sienna in 2003 there has been a slow refrigerant leak. Finally an independent mechanic replaced the lines and no more problems."

"AC stopped cooling in Feb. Added refrigerant and cooled for 3 months and quit again. Added refrigerant again and cooled for 1 month. Not cooling at present time."

"It has a slow leak in the evaporator. Too expensive to fix. Needs to be recharged about every four months."

"Rear A/C tube and suction hose for rear A/C was leaking and had to be replaced"

"Ax not blowing cold air. Radiator leaks and electronic control sensor failure"

"the Toyota dealer put in a sealant and the unit has worked fine since"

"As weather warmed I realized it was not cooling at all. A local private garage was able to repair the problem"

"Very slow leak. Pressure was 25 psi. Added 12 oz r134A refrigerant to get 43 psi recommended setting.. do it yourself cost $12.00;"

"Had to recharge the system for the first time"

"Radiator cracked; need to refill anti-freeze on regular basis"

"water pump failure"

"around the thermostat"

"now that the weather is warming up, the AC is not putting out cold air. we will bring it to our machanic soon for the fix"

"Sienna 2004 radiator known to leakage, had a special longer warranty against it, but i missed it"

"The rear AC developed a leak which required an inspection and a recharge of refrigerant. The front AC was OK. With the recharge of refrigerant, I am able to use the front AC but not the rear. We'll see if this continues to be alright when it gets"

"Three leaks. They over filled with fluid then, so it cold air wasn't consistent"

"had to recharge system two times"
