    I was driving on the interstate when all of a sudden I heard a loud noise that terrified me. I quickly realized the glass of my sunroof was gone. There were no warning signs at all and the sunroof was not open when this happened. After inspection it was clear that only the glass was missing and no other parts of the sunroof assembly. I called Hyundai and was told I could bring it in but it would be an out of pocket expense and would be at least a week before they could get to it. I wasn't sure of the date so I put today's date.

    When I was driving on the highway there was a sudden knocking sound coming out from my engine. I dropped off from the highway and checked the engine and there was a smoke coming out from the engine it was scary. I took my car to the dealership and they took some time and they said I have to replace the engine. Even it is under a safety recall they decided not to replace the engine and they are saying that the engine is rebuilt. Please help me to get my engine replaced, I am a student I am not understanding what to do with this. NHTSA is my final hope to help me in this

    In May 2022 the engine was recalled and replaced by Schomp Hyundai located at 100 Havan St, Aurora, CO 80010, and I purchased this car right after the engine recall. Since I bought the car vehicle the engine has been making noise and the AC and heater smell gas and burned fuel inside the vehicle through cabin air vents. I took the car to the Schomp Hyundai and asked them to fix the noise problem as the engine is not properly installed but they refused to fix it and asked me to pay $180 to diagnose the problem and to pay additional for the fix. The second time when I took the car for the gas and fuel fume and I was told that it is not part of the engine warranty; I have to pay $180 to diagnose the problem and pay additional for the fix. As the engine was replaced, the service may have resulted in damage to the high-pressure fuel pipe. While maneuvering the engine into place, the fuel pipe may have been crushed, poorly torqued, or simply not aligned properly. The dealer is not accepting any responsibility.

    when driving randomly the cars engine will rev really high while pressing the gas pedal but the car doesn't move. After a little while the car eventually makes a loud clunking noise which shakes the car and typically causes the tires to spin. It seems to happen when the car is trying to decide whether to switch the gas engine or back to EV mode. This has been happening for a long time an even after the engine was replace under the recall. This is a safety issue that causes major concerns for myself an passengers. Also it happen when turning onto highways or exits which at high speeds there is a high likelihood of causing an accident. I have reported this to Hyundai several times but they cannot figure out the cause but rather keep trying different things an charging me. the car also seems to burn oil fast which doesn't make any sense being that its a newly installed engine.
