Hyundai Sonata

"It might just be the child safety locks on passenger side door and windows, but both front windows refuse to shut regularly. The driver's side refuses to recline."

"Passenger-side front door handle broke while passenger was opening it. This was in Dec 2017. Apparently, it was a defective grommet that held the handle assembly in place, It took the dealer 20 days (over the holidays) to repair this handle. This was the second occurrence on my Hyundai. About 18 months ago, the same grommet broke on the drivers-side rear door. That only took 10 days to repair. I will be looking for a different brand of car when I purchase or buy my next one and it won't be from the Vision dealership."

"Power door locks will lock me out of the car even with key in the ignition and engine running.Had to start carrying a spare key.Dealer worked on this problem twice but was unable to duplicate.They set locks to open when car is placed in park to see if this helped. That was about 7 weeks ago and so far no problem,however I still carry the spare key!"

"The passenger side exterior power mirror pops out and dangles by the power wires, slapping against the door and scratching the paint. I have taken it to the dealer several times for repair, but they can't seem to fix it. Now I can't change the angle of the right side mirror without it popping out of the housing"

"Drivers side seat belt failed to retract fully. Many times were closed on by the door. If I tossed the belt on the seat I'd end up sitting on it the next time I used the car. I had it in the dealer 3 times and they finally did a partial fix on this item so it's not as irritating"

"fixed with brand new one thank you"

"Driver side seat belt wont retract fully. Dealer had to order the part and said they would call Me been six weeks no word form Hub Hyundai. Also automatic truck opener unlocks but trunk wont open by its self when You walk up to it with Your arms full of stuff. Hyundia said it was not covered but they show it as a feature in their commercials."

"the frame for the seat controls breaks off and becomes loose. 3 times"

"Recall for roof blowing off when driving"

"The car was recalled to fix a defect that could cause the sunroof to detach at highway speeds"

"Factory recall"

"It had a recall about something having to do with the sunroof mechanism. I don't know exactly what was wrong"

"Recall"

"The wind deflector dislocated while roof open on interstate. Could not close roof. Dealer repaired , provided loaner at no cost."

"The automatic open feature on the trunk works however the truck does not pop up far enough."

"The remote on the trunk stopped working...now only with a key...after about 16 months."

"Hood metal not very strong, too easy to get small dents in the hood that can't be fixed."

"Coming from the panaramic sunroof"

"Squeak in sunroof area. Not a big deal but noticable"

"Head liner and sunroof rattle severely. I've taken it in several times and they fix it but it comes back within a short period of time"

"Sunroof was noisy, when I told the dealer the database told them the likely cause which dealt with lubricant and fixed without charge"

"First time I took it to the dealer, they replaced a rear wheel bearing. That did not resolve the problem. When I brought it back, they determined that it was an alignment problem that had caused the tires to scallop. So, I got to pay for an alignment AND a new set of tires, with just 15,000 miles"

"It squeaks if I don't use within 4 days. The longer I wait the louder it is."

"Panoramic sunroof rattled they adjusted it. Doesn't rattle, but in warm weather it squeaks on a rough road."

"From day one the panoramic sunroof makes a rattling noise and I was told that it's a design flaw. Other owners confirm this problem."

"Major tire noises"

"Electric seat adjuster motor burned out"

"The sunroof, which I had to buy to get other options, has an annoying squeak that cannot be fixed. The dealer said they cleaned an lubricated it, but this did not work. The didn't seem to care and have no interest in fixing it."

"Squeaks from the panoramic roof"

"Experienced grinding noise when going uneven pavement in rear roof line."

"Can hear wind no noise sometimes. Have to turn radio up"

"above 50 mph wind noise is loud"

"high rpm idle: 1250r rpm"

"Vehicle recall. Oil leak infiltrated timing computer causing loss of power and tripping dashboard warning lights. Successfully repaired under warrantee at no cost."

"This is related to the electrical camshaft timing motor."

"Oil leak on CVVTi sensor. Handled as part of a TSB in a Hyundai shop free of charge"

"Had the CVT oil gasket come out twice when the temperature was around -10 F to -20 F"

"Blew the valve gasket, rather suddenly for no apparent reason. Plugs were fouled because of it. Hyundai would pay for 'cleaning' the plugs, but not replacing them at 76,000 miles with replacement scheduled at 90,000. Turbo charger was also leaking suddenly quite a bit and the dealer fixed that a half cost. All told was out $800 repair 'under warranty'. Truly only a partial warranty i guess."

"gasket/seal caused oil to leak into and fowl spark plugs - this happened 3 times and was repaired under warranty"

"GASKET FAIL ON MOTOR , VEHICLE REPAIRED AT NO CHARGE. MILEAGE WAS 38267"

"Check engine light came on. Cover and gasket failed allowing oil to fowl spark plugs. Was covered under warranty. Same thing happened a second time within 2 weeks of original incident. Was repaired under warranty"

"OIL GASKET FOR THE CAM SHAFT DRIVEN FUEL PUMP REPAIRED UNDER WARANTY"

"No oil leak. Engine burning oil, about 1 quart every 1000 miles. Excessive!"

"seal leak at crank shaft"

"Common problem apparently, the fuel door latch breaks without any user error from simply activating the opening mechanism from inside the vehicle, so the fuel door is locked and cannot be accessed. My wife was stranded when she got to a gas station and couldn't fuel up. They charge $350 for that repair."

"when set to a speed the cruise control makes the car speed up and/or slow down when going up or down a hill. it is like it has to re seek the speed set"

"front driver fog light and rear driver light were out on most occasions"

"One of the front parking lights stopped working shortly after taking delievery of the cehicle. The light was replaced immediately and has been working fine since."

"Had this problem since We drove it home brand new, HID low beams were aimed too high, causing other drivers to flash their lights because I was blinding them, and high beams made no difference on visibility down the road because they were aimed way too high and lit up the tops of trees not the road ahead, had it to the dealer for this problem about four or five different times, first they said that headlights could not be adjusted, then on another visit they said there was limited adjustment and"

"Car has HID headlights, they were defective when I picked up the new car from the dealer, took over two years and three or four trips to the dealer before a new service manager swapped out the defective ? assemblies. PROBLEM High beams pointed into tree tops and low beams were too high causing me to blind other drivers at night,causing them to flash their brights at me, Got to the point I would not drive the car at night, Dealer said they could not be adjusted but was able to adjust them after which they were too low, took it back to dealer and had then adjusted back to factory settings, finally they replaced both left and right headlight assemblies under warranty with new ones cost $1600 each, $3200, plus labor had to take front end r assembly off car, now headlights are marginally acceptable, Low beams OK but not great, No flashing from other drivers, High beams still way too high but marginally functioning, they over shoot most distance objects road signs but light up the overhead freeway signs COOL but I would like the light on the Road, What A Concept This appears to be a design problem which I suspect has affected many drivers, made for dangerous night driving till they were replaced over TWO YEARS."

"Interior light does not go on when the door is opened. I am currently waiting for a replacement part to arrive"

"Keyless (push button on door handle) entry on drivers door handle would stop working, first intermittently and then completely. Took car back to dealer three times, last time 1 week ago. Seems to be working ok now"

"Electronic door opener and starter will not function. Must use key to open door and touch electronic key to starter Suspect that battery and/or recharging function is not working. Previous car electronic key (camery) was still functioning after 16 years."

"Remote control from cell phone app"

"Tire pressure monitor does not go off even when the tires are fine and it requires a trip to the dealer every time"

"The sensor keeps showing a pressure decrease every day it sits."

"Emergency/parking brake light not working. The switch on the emergency brake peddle was replaced"

"Will not heat up in winter"

"When temperatures are high in car temp gage blinks not letting controls Engage do very long time"

"Blower motor was making noise especially at low speeds.Dealer replaced it @57000 miles, no questions asked. Know it works great!"

"Air conditioning would not get cold enough"

"The evaporator coil was allegedly damaged by a rock and needed to be replaced at a cost of 1200."

"The heated seat feature stopped working and it will cost $600 to repair."

"same"

"The climate control system is my only complaint about this vehicle. I am constantly adjusting the temperature whether I am using the AC or the heat. The windows fog up, and you cannot just set the temperature and let it go. It gets too hot or too cold, and I have to either shut it off, or lower or raise the temperature. Having the windows fog up is really annoying. Otherwise, I love this car. i have owned cheaper cars with much better climate control systems. This is my 3rd Sonota, and all have had this issue."

"Defroster does not have good air flow to keep windshield clear"

"It involved the "knock" sensor. In September the check engine light was flashing & the car would not go over 30 mph. New wiring harness was installed. Was fine until March 2, 2020. I was traveling from the Cleveland auto show home to Cincinnati. Luckily I was in a rest area when it happened. Car was towed (30mph doesn't cut it on I-71. The dealer reprogramed it said I could pick up the car & return the rental. Soon after they called to say the check engine light was blinking again. They brought me a 2020 Sonata SEL new off the lot as a courtesy car. I got my car back April 17. (much of the time delay was due to coronavirus chaos) Ultimately they replaced the knock sensor tested the car for 3 days & returned it to me.(2 hour drive each way) All of this was covered under warranty even though this car is out of warrantynow. Except for the coronavirus I would probably have lease a 2020 Sonata limited. I would not buy one in a redesign year. Sonata offers what others don't a lot of equipment & easy to use controls although the 2020 Limited controls are not as simple. Still those controlas beat Honda & Mazda. I'd buy a Camry, but I can't get a heated steering wheel, ventilated seats, etc. I would also only consider a 2017 or older Camry due to headlight ratings. But for now I'll keep the Sonata."

"Major recall of anti knock computer harness. Part was back ordered and had to wait for part to be shipped by boat from Korea. Had loaner for two weeks at Hyundai's expense."

"Car has an ON/OFF button which is supposed to start engine in one push. In 95% of all cases, it takes two pushes to start engine. Dealer says he can't reproduce that behavior"

"Please see my first explanation for a complete description of the problems"

"I have had problems with spark plugs misfiring twice and had to replace all spark plugs. It causes the engine light to come on and the car idles rough when stopping."

"I had problems twice with the spark plugs going bad and causing engine misfires, engine light to come on, and high idle when stopping."

"Ignition coil was not working properly"

"Premature wear on passenger side ball joint. Replaces under warranty"

"The steering intermittently become hard to steer (of great concern) and the car was returned to the dealer. They loaned me a car and my car is still at the dealer for repair"

"When loaded for a long trip, the OEM tires wear quickly (probably because the back end squats, which I think is because the shock-absorbers are not strong enough for the load. I had to replace the tires early with better than OEM tires."

"Electronic power steering went out and became very difficult to steer. Components had to be replace after being towed to Hyundai dealer, under warranty"

"The steering has a thump sound when the car is cold, the entire wheel could be moved side to side 1/2 a inch of the dealer said nothing wrong but the movement was fixed even if the thump never was"

"The entire rack in pinion was installed incorrectly and needed to be replaced when the steering wheel was turned to the right the wheels would rub against the control arm"

"right rear wheel bearing assembly failed,it got so hot the bearing assembly turned blue"

"The ball bearing prematurely wore out and had to be replaced"

"A mechanical camshaft timing system works only 1 half of the engine. The other camshaft is timed with an electrical motor. That filled up with oil and destroyed the electric motor. This happened 2 times over the 2 years."

"Hose to the turbo system developed a hole in it. Took it to the dealer because I heard a hiss sound. They order the hose told me I would be fine. Part was on back order. After two weeks of driving with the hose like that the car stalled on me. Had to be towed to dealer. I got a loaner. It took about 4 more days for part to come in, then I got my car back"

"cracked air intake"

"Air pipe from innercooler to engine came loose (during a long trip) causing significant loss of power due to lack of turbo boost. Fixed by independent mechanic, but failed again. Fixed by dealer under warranty, but failed again. Fixed by dealer second time with replacement air pipe (hose) under warranty and has worked fine since."

"It failed and had to be replaced... we took it in for service and had to return it 3 times as the unit kept failing. They finally kept the vehicle for two weeks to obtain replacement parts. However we were given a replacement vehicle"

"Decrease in performance."

"Turbo charger had a failed seal. Pulled oil into engine. Hyundai has issues getting part. Was without car for over a month."

"During a trip the car stopped and refused to re-start, it was towed to the nearest dealership and we were given a rental car to complete our travel. Returning out-of-state 10 days later to pick up the car after 4 fuel injectors were replaced"

"Fuel injection system clogged, causing engine to misfire."

"They buried the fuel filter inside the fuel pump inside the fuel tank where you can't possibly change it, costing $2000 of labor for a $10 part"

"fuel pump failed...car unavailable for 3 days"

"Car would not accelerate and the check engine light was on. Dealer said it was a programming problem and was subject to a recall"

"Sensor problem caused the vehicle to suddenly lose power. Took to independent garage that showed recall indicating that the vehicle should not have been delivered to me without being fixed. Dealer initially wanted to charge me for diagnosis and repair."

"DCT in the eco model is jerky and has actually failed to engage first gear before. Potentially dangerous if turning left at an intersection as it could strand me against oncoming traffic."

"Sporadic occurrence gears down or up to soon. No pattern. slow or highway speeds."

"At my last service, I was told there was a computer update. From the moment I drove away after they finished the service, the transmission does not shift the same. It surges between shifts, shifts way too soon, does not respond quickly when I need it to downshift to go faster, lugs the engine more than it should"

"Diagnostics system notified my of a problem with the car so I drove it to the dealer for a warranty replacement of the E-CVVT this year"

"Car was able to be driven to dealer to get a warranty replacement in January 2019. I was notified about a problem by the car diagnostics system check. The dealer had to replace a E-CVVT"
