I have had this car for less than a year, bought from a dealer, and I have checked the background to which there have not been any type of accident or damage from what was provided to me. It randomly started shaking uncontrollably and shutting off while I was driving. Now mind you, as a pregnant woman driving on the highway, this is not safe. My engine light turned on. Though I could have gotten in an accident, by the grace of god people moved out the way and allowed me to get off and to the side.

I have had issues with this vehicle ever since its purchase 01/2015. I took the vehicle in for service and was told the service contract would not cover my issue and that the issue was caused by lack of maintenance, which is not the case as I maintain the oil in this vehicle and even had to purchase a new battery for the vehicle recently.this car's engine repeatedly stops, especially when approaching a red light or stop sign or at the moment of acceleration. I have had to avoid many accidents due to people driving up on me because I should have been accelerating at the time but my car turned off. The battery would die on this car on a weekly basis which caused me to purchase a battery and there is still no progress in the vehicle. The motor knocks badly upon startup, especially in the mornings. The engine is very weak after an independent diagnostic check. And just last week, as I was driving on the highway at normal speeds, the muffler shield broke, fell, and began scraping against the highway. There are electrical issues as well as the lighting in the car gets dim when we are in the dark but bright when the sun is out. Also, the seatbelt for the passenger's side constantly rings sending a notification that the seatbelt needs to be latched, even when no one else or nothing else is in that seat. I fear that one day I may need that air bag and it might not work because the seatbelt appears to be faulty. Also, another issue, which is not necessarily a safety issue, but an extreme nuisance and also maybe an electrical issue is the car radio and volume will freeze at any given moment and the car has to be stopped and idle for a period of time before the radio is active and able to turn channels again. The safety issues for this car are real and I am in fear that I will get hit from behind due to the faulty engine.

I purchased my 2012 GMC Terrain from clay cooley in irving, tx on 01/05/2015 with an extended service contract. I have had issues with this vehicle ever since. I took the vehicle in for service and was told the service contract would not cover my issue and that the issue was caused by lack of maintenance, which is not the case as I maintain the oil in this vehicle and even had to purchase a new battery for the vehicle recently. I am attaching a picture of the condition of the battery shortly after the vehicle was sold to me to where I contacted my sales agent and he advised me to check my service contract.

GMC refuses to help. I am contacting because I own a 2012 GMC Terrain and we just started having issues with out radio where it will turn on even with the car off. Our GMC dealer said that they have seen this issue alot and since my vehicle just came out of warranty in Feb. It will cost us $150. What can we do since this is a fault in the radio flashing not something we have done. If the radio turns on while the car is off what else will start doing that.

We have had the GMC Terrain shut down twice while driving. Both time the car center console goes completely black and you have no control over the vehicle. We brought it in for service but they could not find anything wrong, after the second time they still found nothing wrong but they decide to replace the cars internal computer. The issue was reported to corporate GM but not much was made if it. After all the news with other GM vehicle I'm concerned this that this may be happening with other GMC Terrain vehicle. My wife who is the primary driver is very frighten to drive the car since this. If you have any further question please feel free to contact me.
