2024 GMC Canyon

Headlights flicker constantly. While being extremely distracting and unsafe while driving, it also causes other driver to think I’m flashing them. This leads them to flashing their high beams at me when oncoming and pulling over to let me pass when in front of me. Also, after I complete a right turn, my left signal flashes 3-4 times. I brought it to the dealership and they said they suspect a “software glitch” but that GM hasn’t determined a cause or solution yet. It appears to affect models built in May/June 2024 and on. I was also told that the display screen in the truck can be/may become affected, which is the only way to control the lights in the vehicle. They could not provide me with a loaner or replacement and said to keep driving the vehicle as-is until GM can come up with a fix, despite repeatedly agreeing with how unsafe it is. I have filed a report with GM as well. I was told to “make noise and maybe they’d get it fixed sooner.”

I noticed within a day or so of receiving my new 2024 GMC Cayon that the headlights would randomly flicker. No specific pattern or time interval just random. When I was finally able to get the truck in to the dealership for service, they reviewed the issue and called me the following day to inform me that couldn't repair it. Seems that GMC is aware and they currently have no fix since all headlights they have in stock potentially have the same issue. It seems obvious to me that driving at night with headlights that will not stay on is a huge safety issue and needless to say I do not want to cause an accident or get cited for an issue the manufacturer has no repair for. Leaving my only vehicle parked at home till a fix is found is not an option either.

The headlights flicker off and on every 30 seconds or so while driving or stationary. This occurs no matter what setting the headlight are in. Other drivers think I am flashing my lights at them and have responded negatively by brake checking me in traffic, flashing their high beams at me when oncoming etc. I am worried that the lights may flicker off and stay off while driving at night. The dealer has recreated the problem but still has no fix. My truck has been in the dealer's shop since mid July.

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.

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.
