On a road trip while highway driving my 2019 cpo hyundai tucson/10800 miles, the car did this big jolt and the forward vehicle collision detection avoidance, hazard indicator & service now lights went off. The engine RPM's revved up very high continuously. When I came to a stop the car would barely go with the pedal almost floored. This made the driving thru the intersections with cars honking dangerous. When I turned the car off, it reset itself and was back to normal. The very next day on the highway, the car did the exact same thing with even a bigger jolt and all the indicators above went on again for 10 seconds. Pulled over, turned the engine off and the car reset itself. I got to my destination I took it to keyes hyundai in van nuys, ca. They decided that the transmission computer needed replacing and did it. After picking it up, the very next day the big jolt happened again also while driving on the freeway. This time the side mirror avoidance system, hazard lights and service now indicator lights went off for 10 seconds. I returned it to that same dealer and they had the car for a week and said that they could not find the problem even after talking to the tech line and engineers at hyundai USA. I said it sounds like the main computer may be the issue but they refused to consider that saying they couldn't find the error codes. They then told me that the error codes recycle itself when turning the the car on and off and get erased!! I have to return home from my road trip and I am very scared to take it back on the road and drive another 1200 miles. It definitely feels dangerous with the car revving at such high RPM's and it barely moving when I bring it to a stop. This occured 3 times now and I am afraid of it happening again and having bought a lemon, potentially. It was purchased @ webb hyundai in merrillville, in in march of 2020 with 3939 miles on it.

September 2019, four months after we purchased it brand new. The vehicles stopped responding to my acceleration on highway speeds when all the technology screens went out in the vehicle. While at a red light the vehicles RPM's will visually go up and down and the vehicle shutters as if it is going to turn off. It has unintended acceleration when I'm sitting at a standstill and go to accelerate the vehicle will jump so to speak once the accelerator is engaged. Unfortunately my videos are too long to upload but I do have confirmation of 2 of the 3 concerns but am unable to record the highway concerns due to obvious safety reasons.
