SERVICE BRAKES, ENGINE
I was exiting off the interstate and all of a sudden my brakes got hard and wouldn’t let me stop. I tanned thru a red light barley missing another vehicle. The dealership says my vaccines pump went out and caused it to strip my valve cover gasket to shreds and now has stripped the gears in the camshaft.

STRUCTURE:BODY
The hydraulics that are intended to hold up the rear lift gate have failed. After opening the lift gate and leaning in to get something out of the rear of the car, the lift gate will begin to close and hit or hurt the person that is standing at the back of the car. I have not shown this to a dealer or independent service provider, but it is easily reproducible. Likewise, I have not shown this to a manufacturer, the police, or an insurance representative. There were no warning lamps regarding this issue. The problem just started happening approximately 12 months ago.

ELECTRICAL SYSTEM, VISIBILITY/WIPER
The actuator that controls the blend door / recirculation door (moves the air from defrost to floor to vent) does not last more than a year in my vehicle. I see on the GMC Terrain forums that it is a common problem. It is a danger when defrost is needed on the windshield, and it doesn't work.

ENGINE
My wife and I on an Interstate Highway when the Check Engine light came on and the vehicle started slowing down. The message "Engine Power Reduced" came up on the dashboard display. My wife was driving and started pulling off the highway. As we left the driving surface, the car cut off. After a few minutes, the vehicle restarted and we drove home (about 12 miles). We took the vehicle to a mechanic who told us the oil was low. No low oil or low oil pressure lights had illuminated before this incident. He also stated that the timing chain would have to be changed and that this was a recurring problem on the GMC Terrain. I have not had any work done to the vehicle as yet. GMC should have a recall for this problem as I have seen many reports on the internet since it happened to us dating back over ten years.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
When I place the vehicle in reverse, my backup camera is not working, resulting in a blue screen with a message to have the camera serviced. Per the GMC dealership, this is a common problem with many of the newer GM vehicles and is a safety item due to not having a clear view of what is behind me. I purchased this safety feature and it not working.
