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.

Possible that headlamps will stay off when they flicker, rendering the driver unable to see during night driving. Since the PIT6203 was created (with the recommended action of replacing headlamp assemblies), GMC is now advising to NOT replace them, but offers no further solution. I've received no official word from GMC or the dealership on that, but while they explore a solution, I'm driving a brand new vehicle with a potentially dangerous manufacturing / build flaw. Please consider escalating this issue to a formal recall due to dangers outlined above.

- Benton, AR, USA

My headlights flicker or blink without warning and I feel that they could fail while on the highway. I purchased my truck on the 1st of August 2024. Gm had issued a service letter for the problem on the 30th of July 2024 but they still sold me truck without mentioning the defect.

- Macon, MO, USA

Both headlights blink randomly. Causes unsafe driving conditions at night as well as possibility for road rage interaction at any time.

- Aubrey, TX, USA

Headlights have a frequent flickering issue. They are constantly flickering on and off. Truck only has 600 miles on it.

- Cedar Rapids, IA, USA

Headlights consistently flicker. I have had other drivers stop me and warn me. Happens every 1-2 minutes on both sides. GM dragging their feet with a repair. I am hearing multiple customers with the same issue. Please put pressure on GM to correct this issue now!

- Finleyville, PA, USA

Headlights are flickering intermittently, causing oncoming drivers to think they are being bright lighted. Which causes them to bright light me. Also, headlight flickering causes trailed vehicle drivers to think I am signaling them to stop. Both situations are hazardous, in my opinion.

- Russellville, AR, USA

Approximately every minute while driving with the headlights on, they will turn off/flicker for a split-second. This makes it seem like I-??m flashing my lights at other vehicles, and also makes the lights turn off while driving for a split second which is distracting. This has happened since the vehicle was purchased new and it happens any time the headlights are turned on.

- Everett, WA, USA

Headlight flickering causing vehicles infront of my truck to slow down or break. Been to dealership multiple times for headlight problem. Recent headlight assembly replacement. Headlight flickering still present in truck after headlight assembly replacement. Blind spot indicators intermittently work, on highway, had couple times I relied on indicators that did not illuminate. Dealer could not find issue but same day I picked up truck from service, blind spots weren-??t picking up some vehicles either passing or getting passed. Steering wheel noise when turning. Dealer took part steering column, but could not find a problem. Was told it was just sound from motor in steering column. Test drive exact model truck and year, no noise from that truck while turning steering wheel

- Belle Vernon Pa, PA, USA

About every five to six minutes my headlamps will flicker. Googled online and found a forum for Colorado and Canyon owners who are experiencing the same thing. Some people on there have said GM is aware of the problem.

- Williamsburg, KY, USA

Lights flicker when driving at night. Drivers think I am flashing, flicker causes a distraction on the road. GM service denies the issue. No warnings. Happens every 5 minutes.

- Riverside, CA, USA

The headlights flicker constantly at night. They very quickly power off and back on appearing to other vehicles as if we are flashing our lights. This is a common issue among the 2024 gmc canyons in the facebook owner groups. Its a safety hazard and could also provoke other drivers.

- Santa Rsa Bch, FL, USA

Headlamps flicker intermittently, every 2-5 mins. Common problem and well documented/discussed on owner forums. There was a tsb issued by gm, bit it was rescinded shortly thereafter. No fix is currently known. Headlight flickers cause other drivers to flash their headlights back at you, as well as other aggressive and unsafe behaviors by other drivers.

- Coppell, TX, USA

LED headlamps on both sides of vehicle routinely "flicker" / "blink". The effect is such that oncoming traffic assumes you are "flashing" them or "high beaming" them. Have had several encounters with motorists honking at me or yelling as I pass by. I was also break checked by a vehicle in front of me on the highway when driving at night. These incidents have made driving at night very stressful..... and potentially dangerous. Dealership has been notified and initially stated that they would replace headlamps and ordered those items. I day before my appointment, they cancelled and said that GM was no longer replacing headlamps and was "working on a fix" PIT # 6203A. No time table has been given. This issue is apparently widespread on 2024 Canyons built between March and June of 2024.

- Quincy, IL, USA

Headlights blink or flicker off and on. Both will do it but not at same time. Seems to be only low beams and happens driving or parked. Have been to dealer and they saw it happening. GM is aware and have a bulletin #PIT6203 Headlamp or DRL Flicker or Flash (July 16, 2024) and #PIT6203A ( July 30, 2024 ) Concerns are other drivers or pedestrians think I'm flashing my lights at them signaling to pull out or walk in front of me. I'm afraid one of these times they will not turn back on.

- Essex, MA, USA

The headlights on the vehicle will flicker/ short out. This creates a high risk when operating the vehicle at night. Vehicle was brought into the dealer for service on 08/05/2024, was told there is no current solution for this problem at this time. No warning light on the dash.
