“Periodically auto will surge forward (without the benefit of gas pedal being depressed.) I managed to stop before there was a crash. Dealer states that no problems like this have been reported. I am certain this is a dangerous situation. The dealer has stated that there is no problem with this car. I have to trust that they did something to stop the surging (computer adjustment??)”
NHTSA complaint #10864279, filed 2016-05, 25,542 miles“Driving one day on a beginning winter morning cr had ran perfectly fine and up-to-date on oil changes previously of six months of buying it then car started to automatically shut itself off every two minutes when driving down the road not knowing that the fuel fumes admitted from the engine do not have a large enough outlet causing my main oil seal to burst and blow my intake and there is no guarantee that this will not be fixed after getting repaired due to not being able to modify the original design.”
NHTSA complaint #11407759, filed 2021-04, 108,000 miles“Earlier this month while driving, our Gmc Terrain began shuddering while in line at a drive-through. A few days later while driving, it died at a stoplight, and when restarted, immediately displayed a warning that there was reduced power due to an oil issue. We were not due for an oil change. We had the vehicle towed to a body shop who informed us that it was leaking oil drastically and had a leak in the rear main seal. We were told it was due to the cold weather and that we were the third Gmc Terrain he had seen in 24 hours with the same issue. …”
