Consumer Description

While driving home from work in single digit temperatures on Monday 01/20/25 the engine of my 2017 GMC Terrain stalled without warning at a traffic light. I was able to restart the vehicle and drive it the 1.5 miles home. When I exited the vehicle I noticed a trail of oil leading up the driveway into the garage. Oil continued to leak from the vehicle in the garage, and we had it towed the next day. Righter’s Auto Repair found the rear main seal had blown due to a frozen PCV system that GMC is well aware of and subject to TSB 5093c.The vehicle only has 64,856 miles.
