2011 HYUNDAI SONATA Complaints

My vehicle has an excessive oil consumption issue that started approximately in September 2021 after I got an oil change and had to put more oil in it after about 2 months when the oil change light went off. I have taken the vehicle to 2 different mechanics and they are unable to find an oil leak. There has been no oil leaking on the ground, no burning smell, no smoke showing, but the oil is somehow being consumed rapidly. The check oil light has not gone off since. I literally have to check the oil level every 2-3 weeks to check the levels. I got another oil change in February 2022 and have had to put 12 quarts in since that time. In July 2022 my car started driving funny with low power issues and the check engine light came on. I had the spark plugs and coil packs replaced. Now I'm dealing with low power on inclines and the catalytic converter now needs to be replaced. The mechanic believes it's due to the excessive oil consumption issue. It's my understanding that several Hyundais have been recalled due to excessive oil consumption issues. The contact has stated that during one incident, the vehicle lost power going up an incline. The oil levels were checked and were normal. A tow truck mechanic was able to get the vehicle started back up so that the contact could drive it home. The contact took the vehicle to a mechanic and was told the catalytic converter was bad. Unfortunately, the part is on back order and the vehicle is unable to be repaired. Aside from the catalytic converter, the vehicle has an oil consumption issue.

While driving the vehicle on the interstate, crossing the expansion joint on an overpass, the check engine light illuminated. Immediately following, smoke began coming from under the hood. Pulled off the side of the road to check, and flames were coming out of the car. Quickly removed what personal items that were possible while the car started becoming engulfed in flames. The car burned until the fire department arrived and put the vehicle out. While we cannot be certain, it is believed that the high voltage wiring chafed and arced leading to the fire. If it wouldn't have been possible to immediately pull to the shoulder, the car would have been engulfed while rolling and could have lead to death. The car is a total loss.

Around 174,000 miles, the motor started knocking, the engine blew, metal shavings in oil.

Engine knocking. If engine would’ve turned off it could have caused an accident. Yes, problem has been reproduced. Component has been inspected by dealer. No, warnings.

Car shook violently 5 Seconds later shuts off on freeway . Took to dealership 3 times they say nothing wrong with it but coils they swapped out coils and still doing something .

My passenger rear brake light will not come on after car has been in repair shop 11 times to correct issue. They have replaced the bulb, socket, light wiring harness, fuse etc. The brake light will work for a very short time after repair shop, but then go out again.

We broke down in the middle of the highway where there wasn’t a emergency lane available. A another vehicle struck the car in the rear .

The contact owns a 2011 Hyundai Sonata. The contact stated that the exterior door lock button was no longer operative. There was no warning light illuminated. The contact stated that the battery and key fob of the vehicle were replaced; however, the failure persisted. The dealer and the manufacturer were notified of the failure and informed the contact that the vehicle could not been repaired under NHTSA Campaign Number: 10V070000 (Latches/Locks/Linkages) as the VIN was not included. The vehicle was not diagnosed or repaired. The failure mileage was approximately 74,800.

The taillight socket is melting disabling the effective use of the brake system to alert other drivers the vehicle is stopping. The light works but can not be reinserted into the given space because it has melted close on the tailight cause my entire tail light to have to be replaced. The light bulb then melted into the trunk space and could have caused a fire but luckily we smelled it and moved the placement. I have almost been rear ending multiple times cause long the oncoming driver to swerve off the road to avoid hitting me because they were not able to see I was stopped. I have been stopped by law enforcement and given a warning thankfully. I have sent a complaint to hyundai and have seen multiple complaints and myself seen multiple sonatas on the road with no tail light/brake light issues. My dealer wants to charge over $600-1000 to repair this imperative issue. There was no indication they were malfunctioning until they had melted into the socket. On both lights. I have read multiple complaints on this same issue. This is an important part of the car that needs to be fixed for driver safety.

A friend borrowed my car to go to the corner store to get me a couple of things while my husband was getting surgery. My friend ended up in a rollover accident after hitting a tree. All recalls were up to date on my vehicle, he stated that no airbags deployed. Now after the vehicle was rolled back over and taken to the tow yard the insurance adjuster was the first to see and the driver airbag had deployed. I was not there I cannot say when the airbag deployed however none of the curtain airbags deployed. Also my friend stated that the car accelerated just before impact he swerved to miss something in the road and ended up rolling the vehicle after hitting the tree. The car should not have been accelerating but it was like the car had a mind of its own. I thought the recall was to fix the air bags. He could have been killed.. no reason these cars are still on the road. Not to mention all of the mechanical issues. And I'm sorry to say that I'm glad my kids weren't in the car.
