GMC Complaints

Headlights are so dim because of the plastic cover that is made into the OEM headlight assembly. The plastic apparently had no UV protectant and the plastic has turned dingey yellow and clouded where it's affected the light output from the vehicle

The contact owns a 2018 GMC Terrain. The contact stated that while driving at 35 MPH, the brake pedal was firm and became inoperable. No warning light was illuminated. The vehicle was towed to a dealer to be diagnosed. The contact was informed that the failure was due to a faulty vacuum pump. The vehicle had not been repaired. The manufacturer was made aware of the failure and advised the contact to call NHTSA Hotline for assistance. The failure mileage was approximately 66,084.

There is an open safety recall and GM is unable to fix it. Because of this recall my vehicle is not safe to drive, no dealer or private seller wants to buy or give fair market value for a vehicle with a safety recall that can’t be fixed. I have seen the resale value drop from $12K to less than $2K since the recall. I should not be forced to drive an unsafe vehicle for an unknown amount of time. This needs to have a remedy.

Tail Brake Light failure The tail brake lights have gone out on a vehicle that isn't 10 years old yet. Tail lights should not go out this quickly and the dealership will kindly replace them at $1300 per tail light. This is absolutely absurd! It is available for inspection. This definitely puts myself and others at risk! Yes, this problem has been confirmed and inspected by a GMC dealer. Advised this is a very common problem with this vehicle. There are no warning lamps or messages to alert when the brake lights have gone out. Instrument Cluster failure The instrument cluster is also faulty in this truck. This is the 2nd time within a year that i have had issues with this. Safety concern is that you will not know if the vehicle is running hot because the gauges stop working. Also runs the battery down as the fan continues to run for about 10 minutes after the vehicle is turned off. Yes, the problem has been confirmed and inspected by a dealer. Advised that this is a very common problem with this vehicle. No, there are no warning lamps or messages to alert you of the problem. You just notice a different noise while driving, the gauges stop working and then when you turn it off, the fan continues to run.

Received GM safety recall notice dated June, 2023. Dealership says no solution yet. When will this be resolved?

The contact owns a 2015 GMC Acadia. The contact received notification of NHTSA Campaign Number: 23V334000 (Air Bags) however, the part to do the recall repair was not yet available. The local dealer was contacted and determined that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. VIN tool confirms parts not available.

The engine - My engine blew because oil evaporated out of the #1 cyclinder, which drained the oil. No warning lights went on and the vehicle stalled in the middle of rush hour traffic. The dealership told me it was because of a factory defect, but no recall on that part of the vehicle. This could have been much worse if the vehicles behind me were going faster than they were and not able to stop before rear ending me. Because this was a factory defect it should have been recalled and I should have been notified of this problem when I bought the vehicle.

Both passenger and driver airbags located behind front seats/where Seatbelt is located blew during a collision, seatbelt locked us in during impact,the cab of the truck filled with white smoke and smelt like an electric fire during impact. problem will be confirmed by a collision center and insurance this week. There’s a lamp warning on the dash board that says there’s a safety warning.

On 4/10/2023, I took my vehicle to a local GMC dealership because it was stalling and didn't have any power. Upon accelerating the vehicle it would stall and take off at a high speed. The dealership has had my vehicle periodically from April 2023 and it presently sets at the dealership because they ain't getting a code, But after the dealership drove the truck for over 200 miles, they were finally able to duplicate the stalling yet are not able to diagnose the problem!! This vehicle is very dangerous to be on the road and I have almost gotten hit twice and I'm not driving the vehicle anymore at this time. I have previously reached out to you all and I would be most thankful if you could get in touch with me. Thank you
