37 Electrical System problem

I own a 2010 GMC Terrain 4 cyl. I have had several different service problems with my vehicle since June 2010. Although the service department at my dealership has been cooperative and understanding through all the service jobs performed on the vehicle, it has become disheartening and frustrating that my vehicle continues to give me problems with electrical, engine won't start up, static from radio, not able to play iphone through usb connection at times, random warning lights coming on and off on display console. I have been given several reasons of "could be" or "maybe" but never an actual concrete reason for all the numerous problems. The computer system apparently gives false readings on occassion to service department at the dealership about error codes and messages or no error messages will come up, even though there might be issues with the vehicle. My concern is with all the electronic issues, engine issue of not starting up, computer messages or lack of messages to the vehicle when there is an issue. . If I am driving the vehicle and don't know there is a problem because the computer system within the vehicle does not accurate report correct data about the status of the vehicle, then how do I know when to get the vehicle to get serviced before I am stranded with my children or worse yet, get into a car accident because of the vehicle's compter malfunction. My dealership in my hometown can only do so much with information provided by the manufacturer; so if they don't know what type of fixes to make, then my vehicle is not updated with necessary fixes when appropriate.

38 Electrical System problem

Failure Date: 03/26/2010

I purchased the vehicle 12/13/09. Beginning around 3/26/10, I first noticed that my hatchback was open when I went to get in to go to work, and it had been parked overnight. This has happened in the vicinity of 15-20 times since that date. I thought somehow I was accidentally pushing the release button on the key; however, I often would not have had the key in hand or in my pocket to do so accidentally. It last happened about 2 weeks ago, I walked out to my parked Terrain in the garage at my apartment, and the liftgate was wide open. Nothing has been stolen yet, but I am careful not to leave anything in it or at least in sight.

My 2010 GMC Terrain awd we had since July of 2010 work wonderful at first. Now, may 25, 2011 our Terrain has several lights coming on. Abs, stability services, awd is turn off,and traction control is not working lights. Onstar can not see these problems in its system. Have an appointment for it in June 1, 2011 at our local dealer. But I would not recommend this vehicle to anyone.
