When the vehicle in front of me stopped quickly, I braked quickly but did not hit the car. At that time, all the lights on my dashboard went off and were still on when I took the car to dealer for a diagnosis.

My 2019 Hyundai Tuscan has been burning oil and the oil has to be topped off every 1,000 miles or so. There are multiple check engine lights illuminated: abs, front collision, traction. These lights have flashed off and on for 3 years but are not light up solid. This sounds like an issue.

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.

I believe that this car is a lemon. Ever since we bought it we have problems with the engine not performing right. I have got the engine system cleaned multiple times one at the dealership and one at Valvoline Oil Change facility. The engine still didn't run smooth. I would always get the oil changed on time and the vehicle has never been in a accident. Now just yesterday the vehicle while driving on the highway just stalled and wouldn't accelerate past 60mph. Now the check engine light is blinking and all of the lights on the dash are on. Also lately sometimes the forward collision lights will come on and other warning lights and sometimes they wont. Another light that intermittently comes on are the auto hold and epb light and this has been happening since we bought the vehicle. I have taken into Hyundai and they basically were like yea sometimes that happens. I have not gotten the new check engine light checked but I am sure that it is something serious because the car won't accelerate past 60mph. I have read on other discussions that there are many problems with Hyundai engines and believe that I am victim to very poor quality manufacturing in this engine. I also have a 2013 Toyota Camry with 180,000 miles and haven't had one problem with it. This car is a lemon and would like to have some help with this please. I have also made a complaint with Hyundai under their drive train warranty.
