2011 HYUNDAI SONATA Complaints

Going down the highway at 70mph the engine just shut down. I couldn’t drive over 35 mph hr.

The contact owns a 2011 Hyundai Sonata. The contact stated while driving approximately 35 MPH, the vehicle inadvertently lost motive power and stalled. The contact stated there was a piston failure in the engine allowing oil to leak onto the ground. There were no warning lights illuminated. The vehicle was towed to the local dealer but was not diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The VIN was not included in NHTSA Campaign Number: 17V226000 (Engine and Engine Cooling). The approximate failure mileage was 150,000. The VIN was invalid.

My engine seized up on me while driving in heavy traffic. I just purchased this vehicle in April 2022, and other than me having to replace a headlight, the car drives smooth and has never stalled or given any check engine, or oil lights, or any type of indication that there was something wrong with my vehicle. I just drove it and out of the blue my dashboard lights go off and my engine locks up while I'm driving. I wasn't able to get the car back started. I had it towed to a shop and they weren't able to get the engine to turn either. I am now resorting to a Hyundai dealership to inspect.

After doing some research, I am now aware that there was a recall 20V-746 or 21V-727 that my car was affected by & was never notified about. On 6/2/2022, I was driving and just exited the freeway. Smoke started coming out of the passengers side of the engine. Cars were honking at me & flames started coming out as I drove into a parking lot. I was terrified as my life was at risk & felt fortunate that this did not happen on the freeway. I feel lucky to have been able to escape this life threatening experience. There is now an open claim with my insurance. I had brake lights changed at Frank Hyundai on 4/08/2022 in National City, CA where they also ran a diagnostic check on the car. There was never mention of a recall & my car was cleared of any issues. In addition to the photos I have attached, I also have videos that I am not able to upload.

The car began exhibiting a knocking noise on 5/21/2022 when increasing speed up to around 60 mph. Vehicle did the same thing again on 5/24/2022 and was shaking for a few minutes around the 50-60 mph mark. I took it to my local mechanic who drove it 6 blocks and then towed it back to his shop because he "didn't want to be the one to blow the motor out." At that point there was a consistent knocking noise in the engine even when in park. I did some research and discovered the "engine rod bearing failure" recall associated with similar model and year Hyundai Sonatas. So I had my car towed on 6/2/2022 to the nearest Hyundai dealership from Alpena, Michigan to Traverse City, Michigan, where they ran the engine rod diagnostic test and my vehicle failed the test. So the service rep at the dealership informed me on 6/3/2022 that my car failed the test and would be receiving a full engine replacement and knock sensors with the 10-year warranty.

Upon accelerating to enter traffic the engine stalled. Subsequent attempts to restart the vehicle have been unsuccessful. The engine will not turn at all. A mechanic determined the engine was locked. Prior to this the check engine light had been on and the defective part had been replaced based on diagnostic code P0449.

The contact owns a 2011 Hyundai Sonata. The contact stated while driving at an undisclosed speed, he heard a ticking sound and then heard something detach from the vehicle. The contact pulled over and checked underneath the driver’s side front of the vehicle and became aware that the coil spring had detached from the vehicle. The vehicle was not taken to a dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 102,000.

The engine failed going down the highway and wouldn’t go over 30min. The engine needs to be replaced agin. But the dealership won’t because there are no open recalls. They should replace with a working engine.
