Tl* the contact owns a 2017 GMC terrain. While driving 32 MPH, the contact's vehicle struck a parked vehicle. The air bags did not deploy. A police report was filed. The contact sustained injuries to the head and mouth, and sustained a mild concussion. Medical attention was required. It was not determined whether or not the vehicle was destroyed. The dealer and manufacturer were not made aware of the crash. The failure mileage was approximately 2,850.
I was driving 9pm on a city st rd, coming up on a mile light that was red. The roads were dry on a 5 lane rd. There was 1 car ahead of my car with their brake lights on . Although not noted on police report the car was stopped approx 5 to 7 car lengths prior to the red light. I had began to slow down but did not realize the driver ahead was not slowing down but stopped. I swerved to the right and as noted in pics below the drivers side of car hit the other drivers passenger back corner.
I was driving down the road at 55 MPH when a deer ran out and hit the passenger side of my vehicle. It bounced and rolled off the drivers side. I pulled the vehicle off to the side of the road. All of the electric components in the vehicle were on. The interior lights were on, the hazard lights were flashing and the console was locked up. I pushed the buttons, but nothing happened. The airbags did not deploy there was a message on the screen that say service airbag (but they hadn't deployed).
My check engine light came on along with a a message that states 'reduced engine power' and a message reading 'service stabilitrek when I was driving on the highway at 70 MPH. This created suddenly jerking and slow acceleration so that I had to pull off the road. I found a forum at [xxx] that reveals that this has been an issue with GMC modes at least as long as 2011.
