Horn has failed twice. The first time it was taken to the dealership and -??fixed-?? - now it has failed again. The second issue is that the car accelerates on its own, both at a high and low rate of speed. While traveling at approximately 60 mph on multiple occasions, when the engine transitions from the electric motor to the gas engine, it will suddenly rapidly accelerate without any additional pressure on the gas pedal. While braking at a low rate of speed, the car seems to fight the brakes and will accelerate instead, propelling the car forward. This has almost caused multiple accidents. At the first occasion (Mar 2023), the dealer did a -??transmission relearn-?? which mostly fixed the issue, but it has aggressively returned only 3 months later (one week ago) and is extremely dangerous. While trying to move to the side of the road and stop the car, the car continues the stop-go jerking/propelling forward and is nearly uncontrollable. The vehicle is currently at the dealership again and has not been diagnosed. On the first occasion they claimed they could not reproduce the issue. There is an open case with Hyundai regarding this. There were no warning lights or signals on the vehicle.

Our Jiffy Lube service center performed and oil change to Hyundai Elantra. A day later customer came back with vehicle being towed. Customer stated vehicle seized for no reason. Our technicians inspected vehicle engine oil and found it to be at proper level, but vehicle was completely dead as if no power at all. Customer towed vehicle to nearest dealership, dealership states vehicle seized due to oil starvation due to improper placement of oil filter. This is a canister filter. There is no right or wrong way to place a canister oil filter. Our service center is left with a $9855 bill. Would like to know if dealership statement is true(2022 Hyundai Elantra under warranty, but denied). Please read dealership statement on third page under description.

After driving the vehicle for about 5 miles I stopped to make a left turn and when I let off the brake and pressed the gas pedal the car crept forward but wouldn't speed up and the gas engine wasn't starting or even cranking. After about 20 to 30 seconds to gas engine started and the car drove fine for about 15 miles then I went to slow down and the car speed up on it own and the adaptive cruise control was off. Then it drove fine for a few more miles then I stopped at a red light and then began to make a right turn and the car did the same as before. It crept forward and the gas engine wasn't starting or even cranking. Then after 20 to 30 seconds the gas engine started and I was able to speed up some but then the engine would rev up but the car wouldn't speed up. It seemed like the transmission wasn't engaging. The car was parked for about 8 hours and then drove to the dealership without any issues. The service department at the local Hyundai dealership looked at the vehicle and test drove it without any issues

My check engine light came on before the car reached 700 miles on it. The car acts like it does not want to accelerate, but the RPMS go up- I have cruised at 60mph (and at 35) and tried to move over to a different lane to avoid upcoming vehicles and the car won-??t accelerate. Merging onto the freeway, again I-??m gaining speed, and then the car quits accelerating. I have had the accelerator all the way down to the floor and still no power. Periodically the check engine light will shut off. I have had the check engine looked at with the reader and the code that comes on is P2261 Turbo/super charge
