GMC is aware of this and still have no fix for the problem. There are numerous accounts of this happening to this vehicle on forums and solcial media.

Where to begin... As I bought my first truck, literally within 10 days after buying the GMC Canyon 2024, the car is shaking uncontrollably on the highway... 35 MPH max speed, extremely dangerous situation, 8 AM on a busy Watterson Expressway in Louisville, KY. I was so scared I was going to crash and potentially get hurt or worse. They told me "they had never seen this happen to a Canyon before" which is obviously a lie. The car was serviced for 21 calendar days, and now my lights are spotty and I can't drive my car at night. I got this truck [XXX]. There was no communication on when it was to be ready. There are issues with a lot of minor things as well like the navigation systems. I have logged every call with the Dealership, Courtesy Buick GMC in Louisville as well as summarized every point of contact, and with very spotty responses and the manager, Frank, wont respond to my emails and was extremely uncooperative as I asked to trade it in as I was genuinely concerned about my safety and he told me absolutely not.

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.-??

Safety Issue: Headlights and running lights flicker off and on every 1-2 minutes.

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 headlight assemblies has a random blinking, flashing, flicker, on/off problem. This causes people to think I am either flashing them or blinking my light at them. Major safety concern!! GM is aware of this issue and does not have a fix. I requested a different vehicle to drive until they fix this safety issue and was denied.

- Billings, MT, USA

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.

Bought -??24 Canyon one week ago. Vehicle headlights flicker a second at a time on their own. Flicker seems to happen once every 1-2 minutes. Flicker can cause confusion with other drivers and ignite road rage.

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.

- Crestview, FL, USA

- Marana, AZ, 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.

- Richlands, NC, USA

Headlights began flickering two days after purchase of vehicle. Infotainment screen that operates the headlights, as there is no physical headlight knobs or buttons, also malfunction and is inoperable. So I can not turn my headlights on or off, they're set to auto and I can not adjust it. Service department at my dealership has been able to replicate my issues and are trying to fix them, but parts availability is an issue. GM has informed me that the parts are delayed with no eta of when they would be available. Issues with the headlights flickering could lead other drivers to think I'm flashing my lights at them as I'm telling them to go ahead and that could cause a wreck. Also with the flickering there is a chance that the lights could completely cut off or go out and if I'm driving at night that would be a very big issue. Especially since the Infotainment screen that I need to operate the headlight functions is also inoperable. The Infotainment screen is also on national backorder per GM. 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.
