“The Kia EV9 Wind I bought several days ago worked fine for a couple of days with a slight vibration, but yesterday I experienced 3 incidents. 1. As I was coming to a full stop at a stop sign, there was a mild grinding noise from the rear of the vehicle. 2. I continued for 100 yards and came to a stop light and the car made a louder grinding sound of gears grinding as I was coming to a full braking stop. 3. I continued for about 1/2 mile. …”
NHTSA complaint #11684001, filed 2025-08“I am submitting a safety complaint regarding a serious incident involving my 2025 Kia EV9.

This is dangerous because the pedals suddenly and unexpectedly behave differently with no input from the driver. …”
