2024 GMC Canyon

Truck began idling very rough. Went straight to the dealership. They shut the truck off and it would not restart. No CEL or messages on the dash. Tear down reveled a failed exhaust valve in cylinder #4. Truck has 10,000 miles. A replacement engine has been ordered under warranty. Luckily, we happened to only be a few miles from a dealership when the failure happened. There was no warning, no prior symptoms what so ever.

The contact owns a 2024 GMC Canyon equipped with Goodyear Tires, Tire Line: Wrangler Territory, Tire Size: 265/65/R18, DOT number: 1M6C8JT1R. The contact stated that while her husband was driving at an undisclosed speed, the TPMS indicated a low tire pressure. The driver pulled over and noticed that the passenger’s side rear tire was low. The vehicle was taken to a tire shop, and it was determined that the tire damaged and the lock was missing. The mechanic located a pair of pliers between the rim and tire. The tire was replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The tire and vehicle failure mileages were unknown.

I am reporting a driver distraction safety issue involving the infotainment system in my 2024 GMC Canyon. The vehicle displays a mandatory “Focus your attention on driving” warning every time the vehicle is started, requiring user acknowledgment. When using the built-in Google Maps navigation without subscribing to GM’s paid Connected Services plan (while tethering to a personal cellphone hotspot instead), the system displays a modal warning stating that a connected services subscription is required. This warning appears whenever cellular connectivity is briefly interrupted, even for a few seconds (such as when driving through a known cellular dead spot). The warning overlays the navigation screen and requires the driver to manually press a “Dismiss” button to continue, even while the vehicle is in motion, requiring the driver to take their eyes off the road to focus on pressing the dismiss button. This behavior creates a safety contradiction: The system warns drivers to focus on driving, then forces manual interaction with the touchscreen during active driving. The interruption is triggered by transient network conditions, not driver action. The behavior does not occur if the driver pays for GM’s subscription service, indicating it is a business-rule enforcement rather than a technical or safety requirement. The repeated appearance of this warning during normal driving conditions constitutes an unnecessary and avoidable distraction. It diverts attention from the road and navigation, increasing risk rather than reducing it. I believe this design violates established human-factors safety principles by introducing nonessential driver interaction during vehicle operation and should be reviewed as a potential safety defect related to driver distraction. We just got home from a trip to West Texas and had to press the dismiss button no less than 100 times while driving through areas with marginal/intermittent cell service. It's a huge driver distraction.

I've noticed an issue since I picked up my vehicle from its last service where the RPMs stay around 1,000 when I let off the gas and should be coasting. The vehicle will continue to accelerate at 11 to 13 mph, and I really have to mash the brake pedal to stop. There is an update notice that popped up starting yesterday, but it will not install. Looks like the update is for the issue I am having. The update was supposed to be installed already per the service bulletin. Update number is N242452130

The contact owns a 2024 GMC Canyon. The contact stated that while driving at various speeds, the steering wheel was rattling abnormally. The check engine warning light was briefly illuminated. The vehicle was taken to a local dealer, where the vehicle was test-driven; however, the failure was not identified. The failure reoccurred, and the vehicle was taken back to the same local dealer, where it was diagnosed as needing a rear intermediate steering shaft, and a retest was performed. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer, where the vehicle remained under investigation. The manufacturer was made aware of the failure. The failure mileage was approximately 4,491.

2024 GMC Canyon Elevation trim 4x4 with 31,000 miles on it always had maintenance every 5k interval. I noticed an upper radiator hose leak significant enough to require a decent amount of coolant and decided to take it in to GMC to get it repaired. Mind you this repair is almost $1,000 to get repaired with the hose itself only costing $148. It's disappointing to have such a new truck and have these kinds of problems and upon research there seems to be several others with the same problem relating to an O ring in the upper radiator hose. Considering the truck is routinely serviced more frequently than required I see this as an issue for someone to run out of coolant and possibly be stranded on the side of the road if gone unnoticed and needs to be properly addressed asap.

16,000 miles driven and my replace brake sensor light came on the dashboard. I took it in to get looked at and was told the Front Drivers Side has 1 brake pad showing a life of 5 while my other pads all showed a life of 9/10. I was told that most likely something stuck inside the brake pad itself causing it to wear unevenly but I don't drive anything but highway and paved roads. I looked around other forums and multiple others are complaining of the same issue. I contacted GM and they told me brakes are a wear item. The dealer told me they aren't sure how it happened, but this isn't right to be replacing brakes on a brand new vehicle I've only driven for 10 months. Multiple others are saying the same thing in GM/Colorado forums.

Break monitors for front breaks have dislodged and caused damage to rotors and pads. Dealer claims this is normal wear! Breaks shimmy when breaking in all directions and squeak when backing. I travel to my work requiring mountain passes during inclement weather. The most important safety method while traveling on snow and ice is smooth steering, acceleration and breaking. With my font breaks shimmying, I am concerned for my safe control of the vehicle. Thank you in advance for your attention to this matter.

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.
