The check emissions light for the engine light came up on the dashboard. Without prior warning or other signs the vehicle lost engine power in the middle of the road. The entire electrical power and engine stopped working and the brakes jammed. This causes the vehicle to become unstoppable in the middle of the road causing a safety hazard to the vehicle, driver, passengers and fellow vehicles on the road. The only way to stop the vehicle is somehow use the gears to shift to parking position, turn the engine again on and try to remove the vehicle from the middle of the road.

But have shown the dealership service department video and have had 3 general motor techs that they hired from hp and been told the vehicle is safe and that there will be no more problems but have been in the vehicle while the problems have happened and have it on video to the point where I almost lost my life yesterday night. The vehicle is a death trap and many customers including myself on GMC Terrain forum as well as online have had the same problem and have been told the same thing that it is nothing to worry about but it is. Please help have been told by gm to keep my mouth shut they would offer me 5,000 dollars for my troubles and that my kids are worth that much from a legal advisor at general motors legal. Have ask to be taking out of the vehicle for something safe and still I'm being told no. . . . . . Please help.
