GMC Complaints

The infotainment systems audio while driving decreases so much that you have to increase the volume to hear it and then will randomly increase to the correct volume level without warning and then decrease again.

Vehicle lifters failed early February 2024 while driving. Lifters were replaced and returned to us. One week later the entire engine seized while at 75 mph freeway. Vehicle currently in for repairs for 30+ days and still not fixed. Have had the Yukon in the shop 8 times for electrical, engine, computer failures all previously identified in complaints listed on this website. Family was put at risk on a known chronic engine failure as told by the service department and technician.

We are not able to get a recall completed with a problem known to cause death or injury if left unrepaired - the recall was listed publicly last May 2023 and no remedy is available to dealers to repair yet

Our airbags have been recalled since May 2023. There is no remedy available. I requested GMC to buyback the vehicle, and they denied. They said they have no solution for me.

GMC1500 Sierra pick up truck. Rear tailgate dropped today, 3.15.2024. Weather was rainy, tailgate was up at the start of the trip. Contacted GM Corp and was told this model 1500 was not part of the recall??

In March 2024 I received a letter from GM saying "that parts are now available to repair your vehicle" relating to the 2023 airbag recall. However, the local GM dealer advised me that while it placed an order for these parts 11 days ago, it still has not received the parts and told me that GM has provided no "ETA" for when these parts would be received. GM has failed to replace the airbag component(s) within a reasonable period of time and as of this writing I have no idea when the parts will truly be available. As a result, our family continues to be at risk from a potentially exploding airbag.

I was driving on the highway with my kids and my car suddenly shuts off. There was no warning messages or other symptoms of the problem... no signs! This took place on February 25, 2024. It was towed and taken to the GMC dealership (coral springs) for 3 weeks now.

Driving at 50mph on straight road. No traffic in front. Truck brakes activated. Went down to 29mph. Then picked up speed on its own.

The contact owns a 2016 GMC Yukon. The contact stated that the taillights were inoperable. The vehicle was taken to the local dealer, who stated that the taillights needed to be replaced. The dealer informed the contact that the vehicle was no longer covered under Special Coverage Adjustment: N182180270 (Tail Lamps Inoperative). The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 104,000.

Dealer install illuminated sill plates GM Part No.: 84667517 causing dangerous distracted driving since they do now turn off when the doors are shut and driving as advertised.
