Toyota Sienna

"The compressor failed and has been replaced 3 times, mechanics are unsure of why it continues to fail. The dealership has misdiagnosed issues with the A/C every single time I've brought it in."

"It failed.(Could not be recharged.) Repair completed with extended warranty"

"A/C clutch engages when car is sitting in the garage. Makes a low pitched sound. Must start car, let it run for a few seconds, then turn it off. It drains the battery"

"Well, it failed in the sense that it wouldn't get the car nearly cool enough for south Florida. Had it replaced and couldn't be more thankful. Extremely expensive, though, $1500."

"Ac system failure cost $1800 Entertainment system failure cost 1500 Airbag sensor failure cost 1200 Front axle failure covered after much arguing Worst Toyota we have ever owned Braking system is horrible Needs new set of tires every 10k Miles due to design flaw"

"it failed"

"Would not blow air conditioned air. Issue with both cooling and fan. Was an issue intermittently, then constantly for 6 months. Had it fixed as warm weather approached."

"Because a sensor failed in the A/C system I had to replace the whole compressor unit because the sensor is housed inside the compressor unit. Makes it easier to build the vehicle but a lot more expensive to fix what used to a minor problem in replacing a sensor."

"Not cooling the car"

"A/C operated intermittently"

"The compressor failed"

"NOISY AT FIRST THEN VIBRATING A LOT. WOULD SHAKE THE HOLE DASHBOARD. FAILED BEARINGS ON MOTOR FAN."

"I changed the cabin air filter and almost immediately the fan started making noise that progressively got worse. There was only one fan available and I had to drive over an hour one way just to get it"

"Stopped working and had to replaced with only 26,000 miles on car and two months after warranty ran out. I have owned 3 Toyota vans and 2 cars. This is the first time I've had a problem with such low mileage"

"Bearing was worn out"

"Fan motor squeals and does not move air on cold mornings -25c"

"The blower motor would squeal and vibrate randomly"

"Noisy. Sounds like a defective bearing"

"HVAC blower made a intermitent high pitched screaching sound. After 5 times at the dealer they agreed to replace the blower assembly at no charge. so far no problems. Cound not use the heater during the winter because of the sound"

"The bearings started to go bad indicated through a loud noise. After approximately 3 months of that noise, the blower stopped working all together"

"Blower motor made squealing sounds at certain fan speeds. The dealer said it was the cabin filter but that didn't work. I had to replace the fan motor even when the car was still under warranty as the dealer said it was normal. Aftermarket fan fixed the problem"

"the fan stopped working"

"The blower fan broke and I had to replace it"

"blower very noisy when cold and vibrates a lot at low fan speed 1,2 3 speed at low setting"

"The blower fan started making a very loud squeal. The fan keeps making the noise. Researched online and found that many others were having the same problem with the fan. Haven't replaced yet because the fan is expensive."

"The blower motor went bad. It was making an awful knocking sound and was slowly losing its ability to move air. Replacing it was a simple matter, that was done on my own, with a phillips head screwdriver and less the 10 minutes of time. The replacement part was fairly cheap, and it works just fine."

"after 8 years blower motor failed"

"See other comment"

"Cracked and had to be replaced"

"System began leaking, source difficult to find. Condenser needed to be replaced"

"Stopped-up evaporator drain was mis-diagnosed by Toyota dealer as leaking ductwork, Dlr. wanted $2300 to re-glue ductwork. Only problem was a spider nest in drain tube"

"Replaced the motor. Heater was not working"

"Leak in the line to the rear ac that couldn’t be repaired because connection were frozen."

"Radiator leaking at 44,000 miles identified by dealer. New radiator required. Total bill $850"

"Chemical smell coming from vent when air conditioner is used"

"Refrigerant leaks"

"Leak was in line to rear A/C. Replacement line was expensive and delivery time was long"

"last july Toyota in Charlottetown recharged the coolant and added dye. No leaks were evident but the coolant had failed again by October. The system was recharged last week by an independent garage at our new location.... the outcome is pending..."

"I can't find any leaks but I have to add refrigerant to keep the air conditioning system operating. About four cans per year. I tried one of the sealant kits and it help some. So I DIMY servicing because an estimate by dealer was in hundreds of dollar's range, trouble shooting and repair. So far it cost me about $30 per year to use the air conditioning"

"Air conditioning stopped working due to low refrigerant. Problem resolved when system was refilled"

"Needed alignment. (Perhaps caused by Michigan's horrible roads)"

"WE HAD LEAKS ON 3 OF THE FOUR. FORTUNATELY WE HAD PURCHASED AN EXTENDED WARRANTY TO COVER THESE. WE HAD A VERT DIFFICULT TIME HAVING THEM DO THIS"

"Boot is leaking grease and replace axle."

"Due to lack of proper diagnosis on a bad battery the power steering failed. It took a non toyota mechanic to solve the problem"

"The Struts just wore out."

"Noise noted. My mechanic for 30+ years told me what it was; he repaired it. No problems since."

"The shocks need replacing"

"shock (L) rear was leaking fluid"

"Front struts leaking at 80,000 miles. Had to replace. Dealer said this was within normal mileage for this kind of wear"

"Was broken and was replaced by dealer at no charge"

"Struts wore out and made my tires premature wear"

"While entering a turn, Rt. or Left, the wheel has a loud clunk and you can feel bump in the wheel, Toyota says they can't find anything, I took the van to a local front end specialist and the said the "upper plate holding the strut is loose" needs to be replaced, the van is out of warranty now. I can't afford to have it fixed"

"I can't blame Toyota for the problem The road conditions in the Province of Quebec are very bad. the repair shop said they can't handle all the work caused by the road conditions"

"After 270000 I figure it was time for a new front end, lots of miles and rough driving!"

"We never detected any problem, but inspection at a routine maintenance appointment revealed that the rear shock absorbers were both leaking. Both were replaced last month."

"Lots of "clunks" from the front end when going over pot holes or even cracks in the pavement. Replaced front struts and I feel the ride is still rough. not smooth. V-E-R-Y expensive repair. $1300CDN. Never owned a car that needed struts replaced, quite disappointed in this repair."

"Front struts started to make noise a year ago and got progressively worse, primarily passenger side. Decided to repair and replace struts on both sides along with the corresponding links. Cost we $1300 parts and labour."

"When I went to tire store for routine alignment check, they found I had a broken rear spring. I had both rear springs replaced at a cost of about $800"

"they just cracked"

"The steering shaft between the steering wheel and the rack was clunking over bumps."

"felt/heard a popping everytime I turned the steering wheel, took it in as I have a medically fragile child and can't afford to break down on the hwy. Found out I needed to replace the rack and pinion totaling $2,400.00. Was told if I hand't caught it early would've had serious issues while driving, so glad I was on top of it."

"I had to replace the clockspring assembly in the steering wheel. It cost $943.40 parts and labor"

"Clicking noise when turning"

"Had to have the steering half shaft replaced (was clunking)"

"Some looseness in steering and slight vibrations in steering wheel while turning. I plan to get it checked at service station soon"

"The steering column was detaching from the column due to a faulty bolt. The dealership tried to tell me it was my issue. After getting upset with them and telling them I wanted an assist through Toyota the steering was repaired at their cost! concerning what turned out to be Tie rods: I called and told them there was a squeaking and was told it was normal. I finally called and said I don't think this is normal because it's pulling and squeaking. Turns out I was right. The tie rods were about to break! They recommended that I not drive the vehicle because it was dangerous and could break at any time! I left the vehicle there and paid over $2,000 for repairs."

"Steering half shaft had to be replaced"

"Steering column experiences a thud or knock in certain slower speed manoeuvres. Not a safety issue according to mechanic. did not repair due to $800 cost."

"Worn out"

"There is a clicking sound and a variable resistance with the steering wheel under different driving conditions. When starting up the van for the first time that day, at times the clicking sound appears to be at its worst."

"both failed"

"Related to the alignment problem"

"Due to the manufacturer design, this vehicle exhibits rapid and extreme wear on tires"

"Mechanic said since vehicle does not have grease zerks wheel bearings cannot be greased and become damaged over time."

"Noticeable noise from the front wheels. Noise was transferred to the steering wheel. Mechanic diagnosed wheel bearing on driver side front wheel worn out. Replaced and noise was gone. 6 months later same noise BUT from the front passenger wheel. Changed wheel bearing and noise is gone."

"Left front hub wheel bearing failure. Dealer incorrectly diagnosed. Tire store caught it. Returned to dealer to fix"

"A little vibration in front wheel (s). Both front wheel bearings replaced"

"The CD player wouldn't play CDs, and had to be replaced"

"Cd player would not recognize a cd it just played or any new cd put in"

"This was a multi-disk changer 5 disk capacity. The changer failed. Would not discharge the disks. Finally removed the disks. system would not load a disk"

"CD player failed. Dealer said integrated with nav and radio - $2000 to replace whole unit. Spent 1200 having it repaired through after-market car stereo place"

"Cd will not eject. Not covered by warranty and must be replaced in total . Cannot be repaired. Cost of whole new unit approx $2300. Stuck CD still in unit"

"It stopped working, and we replaced the whole sound/video system"

"Too Small to be effective"

"Screen would power on and then go black. The power to the backlight was failing. Could still see screen contents with a flashlight. Toyota wanted $3000 to replace unit. Shipped to aftermarket repair center for total of $480"

"Radio/Bluetooth/other systems function normally"‿I just have no display."

"bluetooth linking failed to play music"

"This is the worst GPS I have ever seen. The maps were completely out of date from the time of purchase. I reported this and was told I could purchase an update for $350"

"Navigation System had to be replaced at a cost of $3500. The car was certified, so we had a $100 deductible"

"The in-dash navigation system "crashed" and had to be replaced but it was covered completely under the extended warranty I purchased when I bought the vehicle. The cost would have been around $2000 if it wasn't covered under the warranty!"

"This is part of the same electronic control unit. See what previous comment"

"Maintenance required light came on and I could not reset it using the normal procedure, I drove over 80 miles one-way to get to the closest Toyota dealer to correct the problem, which they did"

"The disc reader stopped working. We needed to replace the battery as it was not going to be up to a Minnesota winter and removing the battery put the radio into theft mode. Because the cd disc for the navigation system would not work, the whole unit needed to be replaced, it was unable to reboot. During this time, the navigation, blue tooth, radio and DVD player would not work."

"The memu for pairing Bluetooth devices is horrible. I am a sw engineer and have worked at Motorola pairing police radios, etc and I still can barely get it to work"

"Had to pair it about about 4 times this year. Also terrible voice recognition for phone"

"The bluetooth has occasional problems recognizing devices I have paired with it. To get around the problem, I have had to remove the device, then re-pair it"

"The sienna has an electronic control module that controls both the gps and Bluetooth phone. The dealer said it went bad and the part alone is over $1800. I researched online and this electronic failure shows up across a wide range of models and years. Very disappointed the Toyota doesn't cover this defect"

"Toyota's phone pairing experience is less fun than hearing fingernails scratch a chalk board. The process is long, complicated, and wearisome compared with nearly EVERY other car company's offering. Completely ridiculous"

"Does not store phone information"

"XM Antenna wiring"

"Sirius radio failed due to antennae failure Ridiculously expensive repair cost."

"Sirius radio worked great until the Toyota dealer messed it up when doing a recall"

"Sirius radio failed"

"The antenna for Sirius radio had to be replaced"

"The satellite antenna broke and cost $600 to fix. Headliner must be removed and is labor intensive and expense"

"Problem with Sirius radio reception"

"Sirius XM satelite radio became intermittent and then stopped operating. Other part of the problem is when we dropped the Sirius XM service they won't leave us alone and keep calling and sending re-subscribe mail."

"Lost the sirus XM feature. the problem was found to be the antenna system. It ment that the entire inside roof had to be replaced. If we didn't have an extended warrinty it would have cost us close to 15oo.00 dollars."

"The volume control knob will not adjust the volume and the Toyota Dealership said they would haVE TO ORDER A WHOLE NEW RADIO SYSTEM FOR $4000."

"The radio had difficulty tuning in any stations. Purchased an aftermarket radio to replace."

"Reception is weak."

"System doesn't always work. Cannot accept external input. Remote control has failed. Dealer has not been helpful in resolving issues"

"I have yet to get the computer to understand my phone commands correctly. Terrible"

"Compared to the Nissan we bought at about the same time, this system's ability to understand voice commands is pitiful. It also has many unnecessary steps required in dealing with the systems"

"Driver side window seal melted. Rear vent seals fell off"

"Plastic trim around the bottom of the front passenger seat has come off at least twice. They did fix while under warranty - we'll see what happens if/when there is a next time"

"Actual problem is with front "bumper" connecting with right or left fender. Front of car is too low - any contact with curb or parking lot curb stops cause the part to separate. Poor fastener system and front is too low to the ground"

"Not ext trim - was the rubber seal between the rear side window and the body"

"After we purchased the vehicle, the front bumper and rear bumper were both loose and compromise safety. Because no accident was reported on the van before or after the sale, we had to fix out of our own pocket"

"Rear bumper did not fit properly, had to take to dealer several times. Problem now only partially corrected"

"Front bumper is made of plastic and is constantly coming off. I see it on other Siennas also"

"loose weather stripping on both rear vent windows"

"Front bumper moulding comes loose easily. Had to replace bottom front moulding"

"Loose rear quarter panels"

"Front bumper cover keeps coming loose"

"Gaskets around the windshield have loosened at the endsame and a gasket on the roof came off"

"Back wing windows loose trim. Loose/disfigured trim at bottom corners of windshield. Door handle bleeds onto paint below."

"Cover for front undercarriage easily will get caught & tear on anything (parking stops, driveway entries, etc), come loose & scoop the ground making it unable to drive until somehow secured until replaced (occurred x 2 & we are currently choosing not to replace due to the poor design or durability of the product"

"Rear and front bumpers disconnecting from body. Had to replace rear bumper because it disconnected and was ruined by dragging on street. Periodically have to take to body shop to tighten connection."

"Recurring issue since purchase. The front bumper cover will not stay on. The sides keep flapping."

"Both the 2004 and 2011 have loose quarter panels. I deal with them by hitting them with my hand when I walk by. They snap back for a time, till I hit them again. They haven't flown of at 95MPH."

"Rear quarter panel come loose. Hit them back in place every time I walk by."

"drivers door at floor. The molding fell apart less than 2 months after delivery"

"Glove box lock failed"

"Rear vent window rubber seal half detached"

"Gaskets around 2 front windows don't stay in place. Was fixed once under warranty, is now happening again"

"the weather stripping either shrinks or moves leaving a big gap in the top left corner of the sliding door stripping on drivers side. Also the stripping on the rear window falls off, also drivers side"

"Mechanically, the car has been very reliable; however, the interior has not held up well at all. The mats were a poor design and came out of their tracks with a year. The molding on the drivers seat fell off. The windshield cowl and trim are falling off, the arm rests both on the door and attached to the seats have failed/collapsed, The stow away third row seats have had multiple issues and required repair. The sliding door alarm goes off every time the vehicle takes a left and slightly leans. Very costly to repair, so we have not. Again, the interior trim, fit and finish, and interior mechanics have been very disappointing. But very mechanically reliable."

"All the plastic ports of the heating/cooling system disconnected. Too much plastic in general."

"The whit body below the windows just fades/chalks."

"Noticed paint on one side of car and the whole top is peeling bad, too expensive to fix. Never had a problem with another car doing this. I usually get it detailed at toyota too so very surprised"

"Scratching for no apparent reasons"

"paint seems to have turned colors"

"Side door was hit by a rock and although the paint is very thick it is now chipping off"

"Paint chipping"

"Our Sienna has white paint that has become chalky and flat despite frequent washes and waxes. We took it to one body shop that said the paint was defective and needed to repaint the whole minivan for $10,000. The dealer wouldn't do anything for free to repair the paint, but suggested it just needed a thorough polishing, which they charge us $300 for. Sure enough, a few months later, the paint is back to flat and chalky. Both the body shop and the dealer shop said this was a common problem with white Toyota's. Wish I had known that before we bought it."

"Paint is peeling all along the roof of the vehicle, concentrated in a spot where a sunroof would be if we had one. Vehicle is parked in an uncovered spot exposed to the Texas sun; the pain't hasn't held up to it."

"Black streak down both sides of the car. Car was does not take it off. Have to have it detailed. Streaks are back in 2 to 3 weeks."

"paint peeling off front bumper"

"Recall of sliding electric door. Door may open automatically while driving"

"The side doors would not open or close properly"

"rear trim lights went out"

"Both tail lights out"

"Apparently the wiring of the third towing equipment caused a computer shortage; however, answer give did not seem plausible."

"The lights are very dim at night and do not brighten the path ahead. Hard to see at night without using the high beams. Other cars I've used do not have this problem"

"Bad connection, sometime can't turn on headlight, need to on & off several time"

"One Headlight or Taillight goes out every few months"

"Regular shorts in wiring blow headlight bulbs several times per year"

"You don't have a place on here for seatbelts. Considering how many people buy this van to haul kids you'd think Toyota would make the back seat belt (female) long enough to use with a booster seat!!!!! (This actually applies to almost every mini va"

"when i touch the door sometimes it locks and sometimes I have to touch it 2 or 3 times. Also, sometimes it locks the doors when I try to open it."

"Only one of the two buttons that open the sliding doors works"

"Aftermarket Engine starter, worked 1 year and now works only sporatically. Installer tells me something is wrong they don't know what, must be my electrical system but I have learned there is a recall on that particular system but Installer has yet t"

"Took it in for a recall on the rear sliding doors. They removed the remote starter that was they or they had someone install. They refused to reinstall the remote starter because it was not installed at the factory. All we know is we ordered the vehicle with remote starter and the tow package and they were installed at the time of delivery. The dealer removed the remote starter and disconnected the lights for towing and informed us they could not and would not reinstall them. Please contact us if you need further information."

"Monitor failed"

"sensor failed"

"Tire pressure light turns on and stays on for various lengths of time. When checked all tires are fine"

"on all the time"

"It has been repaired 3 times and still continues to go on when there are no problems"

"Had to replace rear latch, cost about $600 to fix at the toyota dealer. Car was used so it was out of warranty. Warning would constantly go off when I took a turn or drove over 35 mph an put the driver or passenger window down"

"Toyota uses synthetic oil that is needed to be changed every 10K but the internal warning system is set for 5K and no instructions of how to reset"

"The door open light would come on at random times, when all of the doors were secure. It was determined that the rear door (lift up) latch was loose, giving a false sensor reading. When tightened, the problem disappeared. However, I was told if it oc"

"Was informed the problem was due to third party installation of towing equipment"

"CV boot cracked and leaking. In order to use OEM part did to replace entire shaft. Approximately $1000. Shouldn’t have cracked that soon."

"The boot around the right front CV joint has a small leak. The independent repair shop i use was not able to pull the axle to repair the problem."

"The protective rubber cover cracked/split. Had to replace boot and CV joint"

"The boot(protective rubber cover)on the passenger side is slowly leaking grease. The independent repair shop I use could not remove the axle. I will wait for the joint to fail before I replace it."

"The bearing in the rear differential went out"

"Rear end differential required changing due to defective bearing. Repairs were covered under warranty"

"differential started to fail, probably because driveshaft was out of line"

"Front bearings failed on both left and right, in addition to the left CV failing. Ended up costing 1300 to replace both (full axle-and-CV replacement, both sides). All 4 shocks replaced during the search for all vibrations."

"Required rear axle replacement ($2000!)"

"Rear end needed replacment"

"I had to replace the driveshaft at 145,000 km"

"Alternator filed while driving on a road trip and left us stranded. $1000 later to replace an alternator seems excessive!"

"Warning light -- had to replace module"

"Vehicle stab control light kept coming on. But it actually is related to the engine timing and an oil sensor. Toyota makes it impossible for average user. My mechanic had to research and decide what the engine code information was. It wasn't an easy thing to determine"

"VSC sensor malfunctioned right after van was at dealer for service"

"Had to replace the rear transmission coupler, a costly repair. Based on some online research this seems to be a fairly common issue with AWD Siennas that Toyota knows about. They have redesigned the part that fails but there is no recall, extended warranty or service campaign to address it."

"My oil line exploded while driving and the car needed to be towed and fixed."

"oil line broke going into radiator and caused immediate and nearly total lost of oil. Was a known problem and fixed under extended warranty but vehicle had to be towed over 100 miles to dealer. Concerned that it wasn't repaired before it broke as it was a serious issue causing us to immediately stop driving."

"A hose from the oil pan broke loose, causing most of the oil to discharge while driving. Apparently this is not uncommon with this model, according to the dealership. It was just under 90,000 miles, and the dealership covered it under warranty, including the tow. While inconvenient, i appreciated that they readily paid for the trouble"

"Oil pan and engine seal leak. Was repaired in November 2016 but was leaking again in April 2017 because repair was not correctly done. No charge for making it right by Toyota dealer"

"Timing Cover Gasket Leak. Very minor. Did not get it repaired because it would require dropping the entire engine."

"Airbag warning light came on was the central controller. Toyota wanted over $550 to repair. I local mechanic replaced it to a total of less than $300"

"Tail pipe rusted off"

"Loose"

"The Bank 2 Lower 2 sensor Failed The replacement jober part failed By using a Danso part the problem was corrected."

"With only 40,000 miles on the van, two of the O2 sensors failed. The mechanic preform a full inspection of the emissions system at no charge to us because it is very unusual for the sensors to fail at such a low mileage"

"Warning light came on telling me I had a problem but the message did not point to the O2 sensor. Garage mechanic found that I needed to replace the sensor"

"If one sensor is bad, you have to change all of them to work normally If you change one eventually is going to go bad because the other sensors work at different temperature"

"Between 60,000 and 120,000 miles, my 2011 Sienna reports a P0430 error caused by a bank 2 O2 sensor identical to my previous 2004 Sienna. Repair is now aprox $250 at my mechanic but - the first time I experenced it, I followed the repair path of replacing the catalytic converter, fuel treatments, engine analysis, and the sensors were more expensive in the past. The Check engine warning also disables AWD - a primary reason I purchased the Sienna. Today, I expect to see a P0430 error occasionally through the ownership of my Sienna replacing the Bank 2 O2 sensor after one or 2 warnings."

"Oxygen sensor failed several months ago. We replaced it after several conversations with the dealer who quoted 450.00 for a 90.00 Toyota part."

"I have had two coil failures since this was new. We have not put many miles on this van. I fixed the coil on plug the first time, it was the # 4 cylinder. The second time it was # 5 and I didn't have the time to take the entire intake off. So when I had i repaired I had them replace all the cop's in the rear. We were taking care of my ailing mother and not able to travel so we didn't use our van much. Woith only 18,000 miles I think two coils should not have failed. This is a major failure of parts that should last longer."

"Starter died and needed replacement last winter"

"Died unexpectedly after 2 weeks of starting in very cold weather (-30C)"

"The transmission fluid overheated and eventually, the seals failed"

"Should have a transmission fluid cooler"
