GMC Complaints

The contact owns a 2023 GMC Sierra 1500. The contact stated that while driving at various speeds, the tailgate opened without driver input. The sensor failed to notify the contact that the tailgate was opened. The vehicle was taken to the dealer and the tailgate sensor was replaced. The failure persisted. The vehicle was returned to the dealer where it was confirmed that the VIN was not under recall. The vehicle was not repaired. The manufacturer was made aware of the failure. Vin tool shows no information. The failure mileage was 900.

Headlights turn off and on randomly every few seconds. No fault lights on dashboard. Dealership confirmed issue exists. Dealership was advised to replace control module by GM. This did not fix the issue. Advised to change headlight assemblies but they are backordered with no ETA. This issue causes confusion to other drivers and is a safety hazard while driving at night. No recall issued yet.

Car's back up camera screen has gone black on several occasions. The vehicle has been in the repair shop , this is my fourth time trying to get it repaired. The screen goes black with a red circle and triangle on the screen when the car is put in reverse. This makes backing up difficult because of the vehicle size and blind spot . This problem developed in the first month of having the vehicle and again the vehicle is back in for repair the fourth time for the same issue I've had the vehicle in service for eleven months.

Driver’s and passenger side daytime running lights and headlights flicker off randomly. This creates the potential that the lights may fail while needed at night leaving the driver without forward illumination. It has lead to drivers in front of me thinking I’m flashing my lights at them while following which in turn the driver in front of me slows down excessively in protest of their belief that I am flashing lights at them. I’ve also had oncoming traffic flash their high beams at me believing I activated my high beams at them thereby creating an unnecessary blinding situation. The flashing could be interpreted by either oncoming traffic or a pedestrian that I am yielding the right of way when I actually am not and lead to a motor vehicle accident or a pedestrian being struck or at minimum put at risk.

It appears the timing chain is bad. The vehicle only has 84000 miles and currently the engine turns off and you just coast to a stop in the middle of driving.

No warnings of any kind went off; I wasn’t even going 2 m.p.h. and hit a piece of wood that was right on the edge of the grass next to the road at the park. This is dangerous, especially at a park or other places where smaller children are present if I get that close to something and the none of the sensors go off letting me know there is something/someone that my vehicle could strike if not careful. I have not had it looked at yet, but plan to. No warnings of any kind have went off and it was functioning properly prior to this. There is severe damage to my vehicle

MAY RESULT IN SERIOUS INJURY OR DEATH??? AND ITS BEEN OVER A YEAR SINCE WE RECEIVED THE NOTIFICATION OF THE RECALL WHICH I AM CERTAIN GM KNEW ABOUT LONG BEFORE THE NOTIFICATION, WE SIMPLY CANT JUST PARK THE VEHICLE AND WAIT. I AM SURE THE HEADS OF GM ARE NOT DRIVING ANY RECALLED AIRBAG VEHICLES. SO THE PUBLIC HAS TO RISK SERIOUS INJURY OR DEATH WHILE WE LISTEN TO THE LIES ABOUT “SUPPLY CHAIN ISSUES” THAT HAVE LONG WORN OUT THERE EXISTENCE SINCE THE END OF COVID. CORPORATE GREED AT WORK AND KNOW ONE TO HELP THE NORMAL FOLKS. WHAT WOULD YOU DO??

The contact owns a 2014 GMC Acadia. The contact received notification of NHTSA Campaign Number: 23V334000 (Air Bags) however, the part to do the recall repair was unavailable. The local dealer was contacted, and it was confirmed that the part was 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. The contact had not experienced a failure. VIN tool confirms parts not available.

Been experiencing an intermittent issue. After completing an indicated right hand turn, the vehicle will signal a left turn for 3 blinks. This is a safety issue because the vehicle is signaling a left turn when no turn is intended.
