GMC Complaints

The 6.2 L engine Yukon spun a bearing caused my car to shut down in the middle of the road barely got off the side. Lucky that we were not at highway speeds and nobody rear ended us. When I got to the dealership they did not care that this occurred and GMC customer care did not even acknowledge about the safety of us on the road when this occurred. At this point GMC nor the dealership has an ETA on replacement.

Engine failed during trip on interstate without warning after 23k miles. Car went into neutral and we were without power. We coasted to side of road and had to be towed. Dealership has ordered new engine which will be covered under warranty. There were no warning lights before, during or after the incident — no check engine light. The only indicator is that car started making a rattling noise from the engine a few seconds before we lost power.

MY ONSTAR MODULE CRASHED. I CANT USE ANY OF MY FEATURES. WHAT IF IM IN A WRECK? I PAID SO MUCH MONEY FOR THIS CAR ONLY FOR IT TO CRAP OUT LIKE THIS. NOT TO MENTION THE PART IS ON BACK ORDER AND HAVE NO IDEA WHEN IT WILL COME IN!!

Back up camera is almost useless in very dark situations. Back up lights on vehicle wash out the view and all you can see are the red marker lines. Needs either brighter back up lights or a better camera definition. You cannot see a children's bike or other things while trying to back up.

On February 21st when driving on the highway at highway speeds, the vehicle on its own shifted into neutral and I was forced to pull over onto side of the road before the vehicle allowed me to put back into gear of drive. Upon getting back onto the highway, I noticed and heard the sound of the motor very different and louder than normal, I immediately pulled over to the nearest exit to where the vehicle shut off on its own and did not allow me to control the vehicle. I was stranded at the exit where a number of other vehicles and 18 wheelers were trying to exit, I called the local PD, to come assist with traffic control and had to wait on tow truck to have vehicle towed home, then next day towed to local dealership. Received a phone call from dealership days later that the technicians were able to fire it up, but it immediately lost oil pressure and motor locked up, I am being told by the dealership that the motor will need to be replaced, it is covered under warranty BUT I am being given no timeline as to when it can be fixed.

Engine failed at 10,000 miles while driving down the road. No warnings, engine shut off while driving. I pulled over and contacted OnStar. They got me a tow truck to bring the truck back to the dealer the next day. I was told that I needed a new engine and they don’t know when they’re gonna get one in. It could be months. I had to pay for a Rent-A-Car out of my own pocket. The dealer would not cover the cost.
