   On 2 occasions the battery was drained and a tow truck had to jump the battery.

   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…

   We were traveling not once, but twice at a high rate of speed (75/80mph the legal limit) the vehicle gave one message: Service power steering next message: reduced acceleration. The check engine light turned on, the truck itself jerked and we almost lost control of the vehicle (both times) on the highway. We were thankfully able to pull over and pull to a complete stop. The vehicle was still on, it still ran but I saw an autozone close by both times and received a code for…

   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…

    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…

    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…

    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.
