Upon pulling over and turning off the vehicle, the vehicle failed to restart and required towing on several occasions. The vehicle was towed to the dealer, where a wiring failure was determined. The dealer attempted to repair the vehicle, but the failure persisted. While driving approximately 25 MPH, the infotainment screen turned blank, and a large wrench warning light illuminated. The vehicle independently accelerated, became uncontrollable, and drifted out of the intended lane. The contact regained partial control as the vehicle continued accelerating toward an embankment. The front driver's side wheel was caught in the gutter of the embankment, causing the driver's side of the vehicle to crash into the embankment. The contact's head struck the driver's side window, which was fractured, allowing branches to enter the cabin.

EMT personnel cut the contact's hair t
