Selected complaints filed with NHTSA by 2024 GMC Canyon owners, lightly cleaned up (personal details are redacted by NHTSA).

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. …

This truck was purchased brand new on [redacted]. Noticed lights are intermittently flickering (every 2-4 minutes) when driving at night on [redacted]. 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 [redacted] . 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. …

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 [redacted]. 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. …

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. …

Vehicle was brought in 5/18/24 for check engine light Dealer eventually found broken wire in headliner on right side Dealer repaired wire and I picked up vehicle 5/22/24. Vehicle was brought in 7/29/24 for park assist code dealer found short in wire. Dealer stated that to fix wire would require taking cab and bed off frame. Dealer ran a new wire along frame to avoid fixing properly. Vehicle picked up 8/1/24. Vehicle brought in 9/10/24 for a variety of sensors activated. Dealer stated to me that anti-lock brake module was on NATIONAL back order and not expected until 10/28/24. Ut was not safe to drive the vehicle, and they have had the vehicle from 9/10/24. Also, drivers power window module has to be replaced. This 2024 Canyon has been a problem. I have contacted GM and asked for a buyback of the vehicle which GM refused

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.

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.

The Driver Information Center located directly in front of the driver that contains the speedometer, tachometer, oil pressure...etc., has a very distracting background. The background is a geometric patterns of triangles giving a sense of depth. This is very distracting especially at night. Quick looks to see speed, engine temperature or other critical vehicle information is complicated by this unnecessary aesthetic background. I reported this problem and it can be located here: [redacted] I've been advised to mail via USPS my concern to The Office of Defect Investigation Team which I will do today.

On 2 occasions the battery was drained and a tow truck had to jump the battery. On one occasion after the battery was jump started it took several hours before the brakes were able to be used and the car driven safely. Had to drive very slowly (under 50 mph) per note that appeared on dashboard. After nearly an hour of waiting Engine light stayed on and dealership ran diagnostic and found nothing wrong with the battery nor anything else. Have to start and run engine everyday to keep battery from dying. If not started in 24 to 36 hours, battery will die.

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.
