2012 GMC Terrain SLT-1 4dr SUV (2.4L 4cyl 6A)

Review

I bought my Terrain in June 2012. The first year was good nothing out of the ordinary with regular maintenance. As the end of the second year approached I started having random engine light, Stabili Trak messages appearing. I am on my 4th service call with the dealership. The last time 2 months ago they kept my vehicle for one week and found nothing they could repair. The first time they diagnosed a carbon build-up which they cleaned for a fee, the second time nothing could be found, the 3rd time nothing and today I could not drive much above 55 mph on the highway. The car was sluggish and seemed to have no pick-up. I felt like it would stall any minute. I did stall eventually. Frustrated!!!

I had the same problem and had to replace the throttle body. A dirty fuel filter could also be the problem.
