2024 Kia Telluride drivetrain & axles problems

The vehicle was parked(placed in park on gear shift) in a friends driveway, facing upward on approx. 15Deg incline with the engine idling. My wife exited the vehicle and walked around the front of the vehicle to the houses front entrance where she spoke briefly with the owner inside the front door. On leaving the house the car was gone from where it was left parked. My wife found that it had rolled up the driveway incline until it hit a couple of pine trees at the top end of the drive and stopped.

The contact owns a 2024 Kia Telluride. The contact stated that while driving with the vehicle in Snow Mode and depressing the accelerator pedal while making a left turn, the vehicle stopped. The contact stated that after taking the vehicle out of Snow Mode, the vehicle worked as designed. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not diagnosed or repaired.
