“Just purchased a 2021 Kia Stinger gt awd new about a month ago. Just over 1000 miles on it now and encountered a concerning issue. Sitting at a stoplight with the auto start/stop off, traction control off and in sports mode, I pressed the gas pedal and there was a slight hesitation followed by a pretty forceful lurch forward. As I approached the next stoplight several hundred feet further ahead the car completely stalled out. I took it to the dealer and they could not duplicate it... Of course.”
NHTSA complaint #11412822, filed 2021-04, 1,200 miles“My transmission/engine and brake system failed. I was slowing down to probably 5 mph to make a right hand turn into my driveway from the street when the engine started racing. I heard a loud whine and the car started to speed up. I jammed my foot onto the brake to slow down but did not have the time to try to put the transmission into neutral. The car was not slowing down so I turned right to hit my tree rather than proceed straight and crash into my garage. When I hit the tree there was a large jolt and the car stopped. …”
NHTSA complaint #11496826, filed 2022-12“Since April I have been having the same issue. Sometimes when I am stopped and the autostop is supposed to shut down the engine, the engine just sputters and if I hit the gas nothing happens. I have to put the car in park and shut it down then restart it. I try to shut the auto stop off when I get in the car but sometimes I forget. It has happened at over 20 times that I have documented over the last couple of thousand miles, many times in dangerous locations, in the middle of interactions or waiting for a light. The engine light has also gone on and off over the last couple of months. …”
