“1. Stationery. Approximately 50% of the time when I switch gears from reverse to drive the gear slips into neutral. It takes 2-3 attempts and then finally stays in drive. One time I had to put car in park and then shift into drive because it would not stay in drive. This happens even though I am pressing firmly on the brake and am pushing the shift button. 2. While car is moving. 3 times since I have owned this vehicle the following has happened while I am driving on city streets and highways. …”

“I was pulling into the driveway and put on the brake, and the brakes did not respond. The car crashed thru the garage door. I put the car in reverse, but it didn't respond. It took about 5 seconds for it to engage. Then once it engaged in reverse, it was out of my control, as the car shot back at a high speed, bounced up a curb and hit the neighbor's deck. Again, the brakes were not responding to stop the car. There were burn rubber marks showing the speed of the reverse. I felt the car had control not me. This time it also took several seconds for the car to engage in drive. …”

A few days ago, the car started smoking out of nowhere, though it wasn’t overheating and there were no visible signs of leakage. I took it to the shop, and they diagnosed a turbocharger oil supply pipe leak that is severe and poses a fire risk. I am in a new city with no support system and have a baby. …”

“The contact owns a 2018 Genesis G80. The contact stated that while operating the vehicle, the transmission would erroneously switch from drive(D) to neutral(N). The contact indicated that the failure mainly occurred after driving in reverse and then shifting to drive(D). Also, while driving at various speeds, the steering wheel remained seized and would not return to the center without additional force being applied. The failure had occurred while turning in either direction. The vehicle was taken to the local dealer who was unable to duplicate the failure; no service was performed. …”
