Vsa Warning Light On problems of the 2012 GMC Terrain

I experiencing problems with my GMC Terrain. I have contacted my local dealer (doral GMC, in miami, FL) on multiple occasions with no response. I have submitted a written complaint to GMC on April 10th, 2012 and never received a reply. I've experienced continuous car problems since the purchase of my vehicle. Within the first 3 months of purchase my car had already been kept at the dealer for 30 days on 2 separate occasions. Vehicle problems were, for example; the airbag service light turned on, car turned off while driving on a highway, this issue was taken care of but returned several times to have it corrected as it kept happening. The vehicle also experienced transmission issues, the check engine light also kept turning on and service department couldn't figure anything out with my vehicle. This was my first GMC purchase and it has been my absolute worst experience with any american car company. The latest issue since December of 2017 has been the airbag service light once again and the stability track light. I took the vehicle in for service once again and I was charged for diagnostic service so that the issue could be found for each issue and was told I would have to pay $135. 00 per issue. I only paid for the airbag issue since it seemed to be the most dangerous one and was told by service department that the module kit needed to be replaced. This new charge was $ 823. 90 that I had to pay out of pocket. This issue seems to be a factory one and I would like to be reimbursed since this is a safety feature that should not have happened. I've never had an accident and have kept it serviced and well maintained at the dealer through out all the recalls and service problems. The reason I paid for this service was mainly for the safety of my family but once again, it's an inconvenience.

Several times in 3 years, the dealership can not duplicate the problem loss of power starts running slow, wont go over 20 mph, check stability light comes on, check engine light starts blinking, acts like misfire or no fuel in vehicle, starts anywhere at any time, very unsafe and scary. At least taken to a certified dealership 7 or 8 times and every time they do something differant , yet the problem persists! the vehicle can be stationary at red light and big or while driving going 45 or 65 and drop to 20 mph and not want to go, I push the gas paddle to floor and it does nothing. This has been intermediate and a problem since month 3 of buying my vehicle. This is not safe and the dealership has basically givin up on me and my vehicle.

The contact owns a 2012 GMC Terrain. While driving at approximately 25 mph, the traction control and the stability trac warning lights illuminated and the vehicle stalled. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 68,000.
