2019 Hyundai Tucson: sudden unintended acceleration

Filed Mar 12, 2024 · Engine · CT

The 2019 Hyundai Tucson was being driven home when all of a sudden acceleration was reduced to 25-30 mph. The Engine light went on while this happened. Got the car home, thankfully was off the highway and had it towed to the Dealership. Dealership informed me that it was an engine problem- a cylinder was blown and new engine would be needed on a car that had just reached the 40,000 mile mark. 40 other cars were brought into the dealership the same week and all needed new engines. If this car stopped working on the highway the consequences would have been dire! It is almost 2 weeks without a car- Dealership had no loaners left and we still don't have an answer from Hyundai if they plan to cover the engine still under warranty. We were told Hyundai had been denying allot of engines under warranty. And we were told it takes a long time to get an engine even if approved by Hyundai. If I must rent a car for a month or more, it will be very expensive. If 40 owners showed up at the same dealership in one community in the same week what is happening nationally and why hasn't Hyundai issued a recall? Do we have to wait until people's cars stop operating at full speed on a busy highway causing multi care pile ups before Hyundai speeds up response to repair but more importantly notifies owners of their vehicles this is a problem- a BIG problem!

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.
