“My Terrain is stalling really bad some days and sometimes no problems at all. It does it more when going into reverse, I have to keep giving gas to get backed up. It has also died on me when I slow to a stop like at a light. This is really frustrating!!”
NHTSA complaint #11279342, filed 2019-11, 114,500 miles“2012 gms Terrain 4 cylinder flex fuel- camshaft code, cam sensors replaced, spitting and sputtering, stalled x3 and shut off, fuel consumption noted, loss of power. Gmc dealership refused to perform diagnosis on my car due to my refusal to pay for ruling out the documented fuel leak recall/special coverage. My request was only to have fuel the issue looked at and ruled out, nothing further, to ensure this was not causing my problem. …”
NHTSA complaint #11091129, filed 2018-05, 122,000 miles“My daughter was driving to a friends house. She lost all power, and the vehicle would not start back up. There was 3/4 tank of gas in it. We had it towed to a nearby shop to have it looked at. Upon the vehicle leaving it had a lot of gas on the gravel road. When it made it to the shop there was obvious fuel line issues. This vehicle has not been fixed yet, still waiting on a replacement line from a dealership. This is something that GM should have had recalled and fixed immediately. …”
NHTSA complaint #11386151, filed 2021-01, 182,000 miles“The truck burns oil incredibly fast. Due to this ongoing issue, it caused the timing chain to break and we had to spend nearly $800 for engine repairs. Even after having it in the shop numerous times for the same issue, the truck still eats through oil incredibly fast and it seems to only be getting worse. I received a letter in the mail saying that there was a recall regarding this but that they would send me info through the mail on how to go about fixing this issue, but I never received anything else about the recall.”
NHTSA complaint #11280646, filed 2019-11, 120,000 miles“Vehicle began to use excessive amount of oil and idel up and down and sometimes even shuts down. After about 3 months while driving on the interstate it began to shut down while in motion. I called for someone to check the vehicle out and he arrived called someone to check the vehicle and he actually told me it seems to be the motor gone bad but he asked would I drive it back home if he followed behind. It literally scared me and my 4 children to death when it shut down while in motion with that kind of speed so I don't trust putting my children in it now. I don't think its safe at all. …”
