What 369 owners told NHTSA about the 2019 Hyundai Tucson Hybrid Hev

My 2019 Hyundai Tucson, VIN [XXX] , has developed engine knocking, which may indicate internal engine failure. A mechanic has suggested a possible loss of cylinder compression, though the exact cause has not been confirmed. Hyundai vehicles from similar model years have experienced engine failures related to bearing wear and metal debris, leading to stalling, loss of power, and complete engine failure. These failures present a serious safety risk, particularly if the engine fails while driving. I am concerned that this defect could result in sudden loss of power or engine seizure, increasing the risk of an accident. I am submitting this complaint to ensure the issue is properly investigated and addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The TSB needs to be replaced according to the Hyundai Dealership. This is a known problem and would normally be covered under warranty but I am just outside of my warranty window and it just started happening. The entire audio system, touch screen controls, and hands-free controls do not work. The touch screen freezes after a few seconds and freezes on my backup camera creating a major driving distraction. The audio system does not shut of once the vehicle has been turned off creating a problem for the battery which I have to manually disconnect or it will continue to power my touchscreen system even after I leave the vehicle. The lane assist, blind spot indicator, and any beeping warning sounds do not work because of the failing TSB. I cannot change my cars settings or hear any warnings from the car's sensors. I believe this is a major manufacturing flaw and Hyundai will not fix it even though those warning sounds are part of the safety features of the vehicle and are a major player in driver safety. The radio controls do not work - volume included. I cannot adjust any noises in the car and beeping warnings are no longer sounding. I am worried that this problem is also affecting any and all car audio warnings such as the forward collision warning, parking collision warning, and lane departure warning.

While on the road, the 2019 Hyundai Tucson Value dashboard warning lights lit up and stated to check the Lane Keeping Assist and the Forward Collision Assist. The engine light, anti-skid light and power steering light came on as well as the car began to decelerate while in the middle of traffic. I pulled over and turned the car off. When trying to turn back on, the car would not start again until I began pumping the gas with my foot for a few seconds then it started; however, now the engine light was on although it drove normally after that. This has happened to me a few times now, but is very scary because it gives no warning and when I take it to the dealership they can never find anything wrong with it.

Blind spot warning becomes disabled sporadically? Engine needs to be turned off and restarted to reconnect Blind Spot Warning. This has been an ongoing problem for the last few years. It never shows up when brought into dealer for inspection? Nor are there any computerized “messages” in the system? The below “Additional Details” only reflect yesterday’s occurrence. This problem happens on a regular basis. with no regularity?
