Headlights flicker (on/off) very rapidly, independent of each other, at random times.

- Hayti, MO, USA

The headlights flicker on and off frequently (every minute to two minutes). This put my safety at risk for not being able to see the road clear and causing a acident. It puts other drivers safety at risk because they get flashing lights pointed at their windshield and can cause and accident. It is also a safety risk because other drivers assume the flickering is being done by me the driver on purpose and I am concerned it will start road rage or another driver to escalate thinking I am road raging at them. Dealer is aware of the problem. No warning lamps. Started with 40 miles on the truck.

Headlights have an intermittent flicker that happens every 2 to 3 minutes. This flicker is a complete shutdown of the headlight for a fraction of a second, but long enough to notice and have other people in other vehicles notice as well. It is repeatable, and has been repeated by the dealer. It puts my safety at risk. Dealer stated and produced a bulletin that states they are aware of the problem, but do not have a fix for it yet. Bulletin is PIT6203A.

This truck was purchased brand new on [XXX]. Noticed lights are intermittently flickering (every 2-4 minutes) when driving at night on [XXX]. We took vehicle in to dealership (Jessup Automotive) on 8/23/24 where is was purchased and work order stated, "Engineering is aware of this concern and is working towards a resolution. It is no longer recommended to replace the headlamp assemblies as it has been found that the issue is present in the replacements currently stocked at CCA. This PI will be updated when this direction changes." Other vehicles think you are blinking your lights at them. We took a video. Also, there are other vehicles of people having same issue on [XXX]. The vehicle has been inspected by dealership. We are taking to another GMC to get second opinion. No warning lamps, messages or other symptoms before the failure. Owners on the website mentioned that changing the headlight assembly worked. They stated change module or headlights did not work. This problem has been going on at least since since May 2024. We have paid $40,000 for a truck that we are worried about driving at night. Waiting for call back from GMC now who we called on August 23, 2024 in which they stated they would call back within two business day. I have video, however it won't attach.

Head lights flicker while driving at night

- Hollywood , CA, USA

Purchased vehicle 8/3/2024 and on way home experienced headlights were flickering. The problem continued and is so bad approaching vehicles will flash their bright headlights at my truck. At a 4 way stop other vehicles think I-??m flashing them to go. This flickering makes it impossible to drive safely at night. It-??s not only a distraction to me but other drivers as well. I brought the vehicle back to the GMC dealer and was told they were aware of the problem and have no solution to correct it. This is an unsafe vehicle to drive at night and is a distraction to other drivers. The only response from GM is they are aware of the problem.

Since new headlights have flicker. Took to dealership, they stated that this is a known problem with the 2024 headlights and they have no repair and gave the truck back. NO DATE OF REPAIR PROMISED OR IMPLIED. The headlights are not just an immediate danger on for driver in truck but on coming traffic. I have been pulled over for "flashing" a police officer, flip off from other drivers that think I am flashing them. Please help the entire 2024 canyon population as this is a common problem.

- Corinth, TX, USA

Headlights frequently flickering. Flickering varies from 30 seconds to 5 minutes in between. Very random and unpredictable. Service department at the dealership was able to replicate the issue. They found a bulletin, PIT6203 that said to replace the headlights, so they ordered new ones. After three weeks I called the dealer and they said GM cancelled the order because replacing the headlights did not resolve the issue. Headlights flickering has caused other drivers to flash their lights at me. Concerned that other drivers may see my lights flicker and assume I-??m giving them to go ahead causing them to pull in front of me causing an accident. Additionally there is a concern my lights completely going out while driving.

Headlights flicker once every couple of minutes or so. This could very well indicate me flashing someone to turn or go in front of me. I have seen multiple internet threads of this same issue happening to 2024 GMC Canyon owners. The car has 500 miles on it and I've noticed it since I've had the vehicle. No warning signs or anything. Seems like it is computer related.
