Engine Shut Off Without Warning problems of the 2012 Hyundai Sonata

I was on my way home the engine shutdown.

While owning my vehicle for 5 years, I have regularly maintained all aspects of the car from oil changes every 3000 miles to recall notices. I was just due for a 3000 mile oil change when while driving on a highway the car shut down the gas pedal stopped, and I assumed the alternator died. I got it towed and mechanic said the engine is done, there is no oil! this came as a shock since I have it changed timely and there was no sensor or light in the car that should have indicated low oil. I read on carguru website with other reviews this happened with the same vehicle model. Very disappointing with this car with low mileage to have to replace an engine so soon.

While driving on two lane highway vehicle shut down without warning. The car smelled of burning plastic and smoke was coming from passenger side under hood. Car was towed to dealer and motor was replaced thru recall. On 8/20 I was scheduled to pick up and was notified that the main wiring harness had melted badly and that it would not be covered. I filed case #11538113 with Hyundai corporate on 8/20, citing that it appeared to be related to the motor seizing, and/or a safety defect. I was denied assistance on 9/20 and contacted the dealership to begin work at my costs. The car is still at the dealership as they are stating Hyundai cannot release the wiring harness. Research on why brought me to similar compaints the appear to warrant a recall.

I was turning on to a city street ,began to accelerate when the engine just shut off. Tried to jump , nothing . Thought maybe it was the starter. Had it towed to a shop to check/change the starter . They told me the engine had seized . Had it towed to Hyundai dealership three days ago. Was told they would get back to me after inspection of the engine that I might have to pay for. Hoping for the best , expecting the worse.

I purchased my vehicle 1/21/15 certified pre-owned w/ 39,011 4/10/15 as I was driving on a town road doing approximately 45 mph, the vehicle shut off on me and turned itself back immediately. The heat was not on prior to the shutdown, but when the car turned back on, the blowers came on full blast. I explained to the dealer it was like my car was possessed. Mechanic only tested the battery at this time, battery is fine, cause is unknown. 8/3/15 engine seized with while driving approximately 60 on a state highway. Engine was replaced and later a recall was announced by the manufacturer. 9/18/16 vehicle shut off again while driving on an interstate doing approximately 80 mph while switching lanes. Lost power steering briefly and the vehicle came right back on, all lights illuminated on the dash, radio came back on blasting (was not like that prior to shutting off). Maybe it was a coincidence or not, but the second I turned my left turn signal on, is when the vehicle shut off. It came back on maybe 3 seconds later. Original dealership claimed a loose connection with the battery caused it, however, they did no further testing or investigating. It is currently at another Hyundai dealership getting assessed. From 2/20/15 until present, I have also been experiencing the controls on the steering wheel not functioning properly: ex. The mode button will mute the volume, the channel changer and volume will start making calls on my bluetooth call log or activate the voice controls. Volume will sometimes changes the channel or will increase instead of decrease and vice versa. Sometimes the channel changer will control the volume or mode, they do what they want to when they want to. Cruise control is inoperable most of the time. I have multiple videos and have shown the mechanics, but they claim to never be able to duplicate the problem. Cause, still unknown.

I received a recall notice in the mail last year. Finally, in February 2016, Hyundai had a fix for the manufacturer's alleged metal debris that was getting into the engine. The car was serviced and determined all was well. Today, June 21, 2016, the car stalled while leaving for work. I restarted the car successfully; however, milliseconds later, the engine shut off. This kept happening every time I restarted the car. The car had to be towed to the dealership. After a few quotes, ranging from $500 to $1600+, and the Hyundai dealer advising that the oil control valve needed to be replaced -- that "it had an extra hole in it that was not from the manufacturer". They also advised that after replacing this valve, the issue still may not be resolved. Additional repairs and labor would need to be done -- at my expense. I inquired if it had to do anything with the recent recall (mentioned above). She advised , 'no'. I find it very hard to believe that these two incidents or issues are unrelated. After reading about the many Sonata owners that have had engine trouble, I'm afraid to even drive this car anymore.

Engine seized without any warnings (as Hyundai states we would have) while driving approximately 73-75 mph. Was accelerating to move from left lane to right in order to exit highway during rush hour traffic on NJ 78 west. Without warning all lights came on and engine shut down. Paying to have a used engine installed with a 1 year warranty. Dealership says Hyundai will not replace our engine for free because we were over the wsrrsnty period.

My children were driving and stopped at a light. When the light changed, my son pressed the accelerator and the car didn't move. It shut off. When he attempted to start it, nothing happened. No lights ever came on on the dashboard. Had the car towed to pohanka Hyundai in capital heights, MD and was told that the engine was locked up and that it was not covered under warranty because I was the second owner and it would cost me $5774,. 88 to have it replaced with a rebuilt engine. I also purchased an additional warranty which I thought was bumper to bumper when I purchased the car in January 2014.

My engine seized with no warning. I was travelling downhill and the motor just shutoff. Had the vehicle towed to the dealer who notified me that the engine was seized. This is a huge safety concern as it could have happened in the middle of traffic.

Smell of gas, this car have had 2 motor replaced one in June 2014/ 2nd in August 2014 and now a third in oct 23, filled the car up with gas, got on the interstate and the car started cutting back, big clouds of smoke came from the rear end, black sutt on the exhuast pipes. The car putter on the interstate, had to get off the road car shut down while try to steer to saftey, once car shut down it became hard to control, went othe the side of rode, hit a water pipe line, car never crank after that. Had to be towed to Hyundai dealer ship. This is the 2nd time I have reported this car. Now it is in the shop awaiting engineering to review it. For the 3rd motor.
