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.

Infotainment system audio not working. Have performed hard reset, dealer reset, dealer service, and still audio is intermintant at best. more than 75% of the time I have no audio or sound at all. No raidio, no sxm, no bluetooth, no onstar. This is a safety issue and there does not appear to be a repair bulletin, and dealships dont know what to do.

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: [XXX] I've been advised to mail via USPS my concern to The Office of Defect Investigation Team which I will do today.

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 the check engine light. The dashboard both times lit up like a Christmas tree on both occasions before spazzing out. We have taken the truck twice to a nearby dealership and they were able to service and “fix” the problem however they said that the first time, and here we are a second time. The dealerships we took the truck to are aware of all the codes (2 pages worth the first time) but we never received paperwork on what was fixed. The second time we are now going to pick up and hopefully receive paperwork on what was completed. My spouse was driving and myself and my daughter were in the vehicle when the jerking happened with the steering wheel. The vehicle is not safe how can I we be driving at the legal limit and lose control of our vehicle. We were right next to an 18 wheeler with a trailer and multiple vehicles on the road each time. The GMC dealerships are aware they have been working to fix the problem however again this is the second time it happened. The messages occurred both times. Service power steering and reduced acceleration check engine light and also no traction control. The first time it happened was [XXX] going to Killeen Texas and the second was [XXX] going to Albuquerque. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Battery dies during vehicle update spontanteniouly. After jumoing vehicle to start it all systems will not return to normal causing brakes not to function normally. I jumped my vehicle after one system update and brakes failed to engage almost causing an acident. these vehicles should not be on the road due to the software safety flaws. 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.
