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 occasion 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 computer 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.

Multiple problems: 1) front right tire well hole/leak found while investigating a complaint of mold odor inside car. 2) initially, the usb and A/C were malfunctioning. Then the car radio stopped working; and now the car will not start (possible electrical shortage related to the above leak?) I tried to charge the battery; however, I believe something may be draining the battery as it keeps dying.

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.

With all exterior lights and one map light on, when using turn signal, all lights will dim when signal light comes on. There should not be that much strain on the electrical system.

Engine cutting out and dying while driving, horn honking at times, vehicle starts itself sometimes, blowing fuses. Vehicle tried to die on my wife while driving almost causing a serious accident. Dealer has not found a solution yet. They have replaced the BCM with no good results.
