ENGINE
There are widespread reports of the O ring seals on the radiator and heater hoses failing and causing coolant leaks. These leaks are significant enough to render the vehicle inoperable and with no cabin heating or cooling. This could lead to life-threatening situations in adverse weather conditions. It could also create dangerous roadside failure situation in heavy traffic, particularly on interstate highways. Dealers are aware of the issue and are currently repairing vehicles under warranty. However some dealers are telling owners that the cooling system is not part of the engine and drivetrain, and therefor is not covered under the original factory warranty if the vehicle has exceeded the initial bumper to bumper warranty limits. Dealers are also telling owners that parts are on backorder due to high demand, and that repair wait times could take weeks. The vehicle is unsafe to operate with a known coolant leak. Video of leak (another owner) here. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN, ENGINE
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.

UNKNOWN OR OTHER
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.

Noticed a coolant leak on drivers side and took to dealership was told was the upper radiator hose but was unable to make repairs due to national backorder and only suggestion was to drive until parts come in and keep a check on the coolant level, My truck only has 28,708 miles and shouldn't have to keep an eye on coolant level I feel that is very unsafe

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE, SERVICE BRAKES, HYDRAULIC
The contact called on behalf of her son who owned a 2022 GMC Canyon. The contact stated while her son was driving at an undisclosed speed, the brake pedal was depressed, and the brakes failed to engage. Additionally, the infotainment screen was inoperable. The front camera module warning light was illuminated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the front camera module needed to be replaced. The dealer made the contact aware of NHTSA Campaign Number: 24V133000 (ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE); however, the VIN was not included in the recal. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

ENGINE
The upper radiator hose on a significant number of these trucks is failing prematurely. In my case, the failure occurred at just over 35,000 miles. Numerous reports on owner forums (such as the Colorado Chevy / GMC Canyon forum), YouTube, and other platforms document the same issue, indicating this is not an isolated incident but a widespread defect. Because this hose is part of the cooling system, its failure can quickly lead to engine overheating and potentially catastrophic engine damage. The root cause appears to be an engineering flaw in the sealing method: GM uses a rubber seal instead of a durable, high-quality o‑ring to connect the upper hose to the radiator. Despite the seriousness of this defect, my local GMC dealer informed me that—since it is not currently a recall item—they could only schedule service for the following week, requiring me to leave the truck with them for 7–10 days before repairs would be completed. This is unreasonable for consumers who rely on these vehicles daily. Given the safety implications and the potential for engine failure, this issue warrants immediate attention. It should be classified as a recall item. Thousands of examples are already documented online, and GM’s own repair data would likely reveal thousands more instances of this same failure.

SERVICE BRAKES
On Sunday, November 16, 2025, my vehicle, which had only 2,004 miles on the odometer, experienced a catastrophic failure of its braking system. The warning lights illuminated, and I received a diagnostic alert text message from OnStar stating that the driver’s side rear tire needed air. Subsequently, the dashboard displayed a brake failure warning, advising me to proceed with caution as the braking system was inoperative. I drove the vehicle home and then took it to a nearby Buick GMC dealership for repairs. I dropped the keys into the overnight box and returned to the dealership the next morning. I was informed that a technician would contact me. On Wednesday, November 18, 2025, at 3:00 PM, I received a call informing me that the braking system was indeed malfunctioning. The technician mentioned that it would take approximately 48 hours to obtain the necessary parts; however, there was a supply chain issue that could delay repairs for potentially 30 days or longer. The vehicle was purchased on April 18, 2025, and had only 2,004 miles on it at the time of the incident.

BACK OVER PREVENTION
The contact owns a 2021 GMC Canyon. The contact stated that while reversing, the back over prevention screen image was solid blue, and there was no image displayed, creating a visibility hazard for the driver. The vehicle was taken to the local dealer, and it was determined that the rearview camera coaxial cable connectors were faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was not included in NHTSA Campaign Number: 22V709000 (BACK OVER PREVENTION). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 46,000.

SERVICE BRAKES, VEHICLE SPEED CONTROL, STEERING
While driving at 70–75 mph on an interstate, my vehicle suddenly displayed a “Brake Failure” warning and limited speed to 62 mph. Power steering failed completely, and braking became ineffective despite hard pedal pressure. Multiple warnings followed: ABS, engine, and others. I was in heavy traffic with vehicles at full speed. Loss of braking and steering control forced me to coast across lanes to the shoulder, narrowly avoiding collision. My safety and that of others was at extreme risk. After stopping, I turned the vehicle off for ~30 seconds. Upon restart, all systems returned to normal—no warnings or issues. This indicates a transient software malfunction, not mechanical failure. No prior warnings or symptoms occurred. The problem has not been reproduced or confirmed by a dealer/service center. I have not scanned or inspected the vehicle. It has not been examined by the manufacturer, police, or insurance. The vehicle is in my possession and available for inspection upon request.

VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM, ENGINE
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.

SERVICE BRAKES
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.

SERVICE BRAKES
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.
