Vehicle was drove for approximately 3 weeks with a used motor, fully inspected and replaced per Hyundai protocol at a registered repair shop after Hyundai denied my motor replacement. Vehicle died due to bearing failure, when brought to Hyundai was immediately denied without entering repair facility due to "vehicle history". video can be provided, cannot attach. Fire was due to starter motor catching fire at failure. Extinguished myself.

This is an ongoing problem, the plastic that the tail light bulb is attached to is melting and I have had to replace the tail light casing already recently. Since the replacement, I replaces a bulb and the plastic is starting to look burned again. Two weeks since I replaced that bulb, the light is out again.everytime I have this problem my check engine light comes on. After a few days it goes off. When I take call the dealer they said if the light goes off they cannot check the problem, this problem started about 3 years after I got this car and now my check engine light is on again and will not go off.the driver side airbag light is alway on since a year ago. No accident. Looks like there are a lot of similar issues with Sonata

The driver experienced a stalled engine while driving. The brakes failed to respond and the steering wheel locked up. The car coasted, despite repeated braking attempts, and jumped a curb and stopped when it ran over onto a person's lawn. The driver attempted to steer and stop multiple times.

While driving to mobile Alabama after our vehicle was inspected and were told that our vehicle was fine, the engine suddenly stopped running in the middle of traffic. We were lucky not to get hit by semi trucks at the time. At the time of this incident we were headed South bound on I-55 at 70 mph. In the right lane with heavy truck traffic, thankfully I was able to get off the road without incident.

2012 2.0T limited with 95K. 12-18-18, while driving from austin to houston tx vehicle loses acceleration on the highway. Check engine light comes on, along with the emergency parking brake light (which comes on intermittently and dealership yet to define problem), and abruptly goes from 75 to 0 mph. Vehicle will not respond to any acceleration and I have to find a way from the freeway to feeder without power. Inoperable. Limped three miles with police escort. Car towed. Dealership cannot duplicate issue. I make them keep vehicle to investigate. They get a code error and change out the ECM for a mere $1400. Meanwhile, I must find transportation in a city I do not live and rent a car for a week. Retrieved vehicle. 2 weeks later, traveling to houston on 12-26, check engine light comes on, car will not accelerate; spitting, feels like no gas getting to engine, heavy smoke from tailpipe. Christmas eve, no place to stop. Barely make it to houston. Inoperable. Car goes to another dealership in houston. Again, without transportation in a city I do not live in. Faulty high pressure fuel pump. Carbon buildup. Another $1100. Prior to that, March 2017, engine failure travelling to houston. Knocking noise. Wont go. Inoperable (luckily, this one I made it to a full stop). Car towed. Waited three months for a new engine (not in my hometown). Had to travel to pick up vehicle. (car had been inspected by hometown dealership specifically for metal debris and it did not get flagged for replacement). Directly after that, while driving in austin. Vehicle stops in major intersection. Inoperable. Towed. Degraded battery cable because the vehicle sat for three months while waiting for an engine. The only warranty was the engine. Can you say lemon? the only saving grace is that myself and my family were not seriously injured when our vehicle became inoperable while driving on a highway.

The car has randomly stalled three times, two of which occurred when entering traffic (right-turn major intersection and entering highway). All lights on dash appear without warning and the car wont accelerate, brake optimally, or steer (like in the last instance). Car won't start back up at all now, won;T even try to turn over. All instances occurred randomly while in motion. The first two times it happened the car started up with a sputtering hesitation, now I am pretty sure the engine seized on the last occurrence.

Arriving at busy intersect when accelerators and brakes ceased to work all dash lights began flashing and I was fortunate enough for light to be green and was able to coast to a stop at shoulder through intersection w flashers and horn blowing ! I restarted car and pulled into a local business w a clunking noise!! was told by my mechanic who has regularly serviced this vehicle that it was the engine ! why brake/acceleration not working ?? I was told he's had 3 other Sonatas in this month that ┐just burned up all the oil ┐ without a light on or anything. I could have been on S busy highway and killed in addition to risk to others.
