This vehicle has stalled on me while driving on the highway and streets. I've taken it into the shop for the problem was told the pc module is going out. The price to fix this a $2300. This should be covered on a warranty. They've me told that it's not. This is a major componet for these vehicle it should be cover. This has happened several times prior. When the vehicle accelerated there is smokes for the tail pipe.
Vehicle stalled on highway would not start had to be towed on 10/1/19.towed to service vendor, not a Hyundai dealer. They stated engine locked. Vehicle had been at St charles Hyundai automotive 8/19/19 replaced oil flow control valve. Contacted Hyundai dealer stated nothing they could do. Mileage 138,000 and all required service had been done. Recall 132 inspection had been done at approximately 58,000 on 2/15/16. Noted number of complaints to NHTSA showing numerous 2011 Sonata had engine failure after the extended format of 120,000 and many had failed a second time after engines failed. This vehicle was built at Alabama plant. The Hyundai dealership stated the vehicle would have to be towed to their facility and inspected. The decision would be Hyundai usa not the dealership. It is hard to understand how this can not be a defective vehicle. The number of units repaired and repaired a second time goes against the averages. The number of fires that have resulted in total loss of vehicles appears to be and indication of numerous issues with vehicles from this plant. It will cost $4500 to replace this engine and Hyundai usa should bear some of the cost. If after engine replacement vehicle performed properly that would prove the correction, but many units had to have the neck filler replaced the plant had a problem. Engines failed with only 10,000, 30,000 65,000, 135,000 miles. The units that burnt were handled by insurance and Hyundai usa not held accountable. Please reopen the investigation on recall 132 the number of owners are bearing the brunt of Hyundai poor quality. Understanding they completely changed that engine in 2012 knowing the 2011 issues could not be fixed correctly
Out of nowhere when vehicle is sitting still, the airbag light keeps popping on. It will stay on for a while, but then go off. I went to have my oil changed and event though it was at 3,000 miles, the oil was low, dark, sludgy and metal shavings were found in my oil pan---engine sometimes sputters. Finally my interior lights won't go off, I have to just keep them to the off position versus "door" so that my battery doesn't drain.

While driving on I-75 doing about 65 mph, without any warning whatsoever, engine stopped. It felt like all power steering, breaks and steering wheel, went away. I was lucky enough to be on the right lane and was able to safely pull over to the side. This happened the night of Sunday, the 20th of October. I had the car towed to my local mechanic where I was told the engine had frozen up and needed to be replaced. I read on line that hyndaui had extended engine warranty on '11 Sonatas to 120,000 miles, so I had it towed this morning to potamkim hyndaui. I bought that car brand new back in 2011, and have religiously changed oil every 5000 miles using synthetic oil every single time. The car had 118028 miles when this happened.

I was driving down the road the engine just locked and stopped. I am not sure whats going on but I was at a speed of about 65mph. I never had a problem with the engine prior.
Engine was replaced per extended warranty regarding recall. Vehicle was taken into massey Hyundai on 09/07/2019 and returned with reman motor on 09/12/19. Since then the vehicle has showed over heating and the backup camera displays a white screen on 10/09/19. Called after temp light came on and Hyundai has the nerve to say they will not pay for the tow. On top of that they person who answered the phone explained the wiring harness wasn't replaced. Temp light hasn't came back on due to my son not using the A/C. NHTSA has not held Hyundai or Kia accountable for issues they no doubt knew about. The recall should have been a buy back for these motors. We are not asking for a new vehicle. We just wanted the vehicle working properly. Now my son is stuck with a vehicle with all kinds of electrical problems due to Hyundai flaw. The electrical system was working fine prior to the engine replacement and Hyundai should be held accountable. NHTSA is starting to frustrate

Who is suppose to refund me my money for an issue that was placed on a recall. Your assistance in this manner is appreciated.

I bought this car 3 years ago. Ever since the day I bought the vehicle, it makes loud clicking noises when you turn the steering wheel left or right while in drive and reverse. In the 3 years that I have owned this car, I have had to replace the tires 4 times, the brakes and rotors multiple times per year, tie rods, and cv joints and yet the car still clicks when you turn. I had the engine recall done in may of this year. They gave me the car back a month later. I had to take it back the very next day because it was leaking copious amounts of oil and making a clanking noise that was not present when I left my vehicle with them for a month. They "fixed" the oil leak and told me the noise was from my front brakes yet again. I had to return the car again a few days later because it was still leaking oil! so they "fixed" the leak a 2nd time and again said the noise was from my brakes. Less than a week after that the check engine light came back on. I immediately took it back and was told that it was just a "loose gas cap" which I never experienced prior to the engine being replaced. They cleared the light and sent me on my way. I had brand new brakes and rotors put on, again, and yet the clanking noise is still there. 5 days ago, the car began driving the way it was before the engine recall, same engine failure symptoms and my check engine light came back on a second time 3 days ago. I have not had to fill it up with gas in 8 days so there is no way that it is from a "loose gas cap." My seat belt locks up and stays locked up if I lean forward. I should also mention that when I bought the vehicle I had to inform the manager that the front bumper was only attached to the car because someone drilled screws into it to keep it on. He had no idea!! I made them replace it before I would buy the vehicle. The paint is constantly chipping off of the "new bumper" they put on it.
