GMC Complaints

LED Headlamps flicker off and on and occurs repeatedly every few minutes. Occurs when vehicle is moving or parked. Occurs in a controlled lighting environment meaning it is not due to the auto-headlamp sensor being triggered by light or darkness changes. There are no error or fault warning messages that display on the dash or control center. No human involvement triggers the flickering. The issue occurs even when remote start is used and the vehicle is unoccupied. I have located dozens of other owners with the same issue with a similar build date from Spring 2024 through June 2024. GM documented the issue with Document ID 6691954 #PIT6203: Headlamp or DRL Flicker or Flash (July 16, 2024). Hazards include the possible signs of headlight catastrophic failure rendering the driver unable to see the road and surrounding vehicles as well as other drivers being unable to see you that could result in injury or death. Vehicles that are being trailed when the flickering occurs interpret the action as being indicated to rush and make way for the approaching vehicle resulting in road rage actions such as brake checking or other forms of violence that can result in injury or death. Pedestrians may interpret the flicker as the driver yielding to them resulting in the pedestrian entering the path of a moving vehicle resulting in injury or death. Oncoming drivers that are being flashed from the flicker are distracted or blinded in a way that could result in injury or death. Please escalate this safety issue to a formal recall due to severe consequences that could result from the faulty headlamps.

There is a current safety recall N232426400 on GMC pickups including the year of my truck. GMC is saying that my VIN is not covered by the recall. However, I have the multi-pro tailgate and it came open about 6 months ago on its own as i was backing up and it caused me to run into my trailer with the tailgate. I put my tailgate up after moving my truck from under my trailer and then when i went to back up somehow the tailgate popped open and i didnt know and it contacted the top of tailgate while it was down.

On July 26, 2024, I was driving my 2018 Acadia, with my cruise control set to 48 in a 45 MHP zone. Nearing a bad curve, I sneezed. When this happened, I tapped the brakes to disengage the cruise control, my passengers side tires exited the road and with both hands on the wheel I tried to slowly bring my tires back to the road. However, I was unable to gain control and totaled the vehicle. A witness stated that she heard a loud pop coming from the vehicle before the wreck happened. I later learned from my insurance that the vehicle had a Recall 17V516000 on it and I was never made aware of it. I believe that this was a factor in me not being able to control the vehicle.

The contact owns a 2022 GMC Acadia. The contact stated while driving at an undisclosed speed, the vehicle lost motive power and the stability track warning light illuminated. The contact stated that when the accelerator pedal was depressed, the contact stated that an unknown fluid was shooting out onto the contact's foot. In addition, the contact stated that the front driver's and the passenger's floorboards were soiled with the fluid. The contact drove the vehicle to the shoulder of the road and turned the vehicle off. The contact stated that when the vehicle was restarted, the vehicle was driven without further failure. The contact stated that the failure had occurred while her six children were inside the vehicle. The vehicle was taken to the dealer; however, the failure could not be duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact stated that the failure had occurred five times. The contact stated that the vehicle was taken to the dealer each time. The manufacturer was made aware of the failure and a case was filed. The failure mileage was 600.

- The vehicle's headlights will briefly turn off during normal operation, it can be made available for inspection - This is a safety issue because: loss of visibility in dark conditions, other vehicles mis-interpret the failure as a signal - The issue has been reproduced and confirmed by many dealers, see discussion forum here - [XXX] - Manufacturer engineers have inspected the component - No warnings or indications prior to the failure.

The headlights flicker. It doesn’t matter whether auto dim feature is on or off. It happens approximately every 5 minutes or so. This is a dangerous situation. It flashes at vehicles as well as pedestrians. This could cause I’m signaling to go in front of me.

The contact owns a 2017 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. 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.

LED Headlamps blink off and back on in a fraction of a second. Seems to be related to low beam setting. Seems to not be related to auto-dimming functionality. Seems to be a narrow build date window from late Spring 2024 thru June 2024. Occurs when vehicle is moving or parked. Can be replicated in daylight by manually turning headlights on in the control center. GM documented with Document ID 6691954 "#PIT6203: Headlamp or DRL Flicker or Flash (July 16, 2024) Possible hazards include oncoming drivers being flashed from flicker. Oncoming drivers thinking they're being signaled by the flicker. Pedestrians or cyclists thinking the flash or flicker is signaling them to proceed and that vehicle operator will yield. Possible that headlamps will stay off when they flicker, rendering the driver unable to see during night driving. Please consider escalating this issue to a formal recall due to dangers outlined above.

SUV gets a slow down warning and it stops shuts off , it’s happened several times now I’m scared!!you wait few minutes it turns back on , mechanic said this a complain about this vehicle all the time , it has not been repaired I’m disabled with no money , I was on the highway and thank God I was on the slow lane if not I would have been killed by an eighteen wheeler. GMC is waiting for someone to die and probably address this issue
