The contact owns a 2023 GMC Canyon. The contact stated that the vehicle had experienced several electrical failures and would fail to start due to a faulty battery. The contact stated that after the manufacturer remotely completed an unknown electrical update on the vehicle, the vehicle started experiencing several failures including a rearview camera, door locks, brakes, and power steering failures. The contact stated that while driving at approximately 5 MPH and depressing the brake pedal, the message "Power Brake Assist" and "Power Steering" were displayed. Additionally, the brake pedal went down to the floorboard, and the vehicle failed to respond immediately. The contact also stated that the vehicle lost power steering functionality.

Driving approximately 45mph while car in front is approximately 50 yards ahead driving at a matched speed as my vehicle and without any prior warning the forward collision alert activated flashing red light on windshield and automatically applying FULL braking until the truck came to a complete abrupt stop in the center lane of rush hour traffic causing other drivers behind to swerve narrowly avoiding serious accident. Had the cars been following closer or an 18 wheeler been behind me during this incident, the outcome could have been much worse. I Manually de-activated the automatic braking but kept forward alert on until the truck could be brought to the dealership for diagnosis. Forward alert went off erroneously multiple times the following days without any rhyme or reason. Not until the final day before the scheduled service appointment did the system de activate itself indicating an issue with the forward collision. Most issues occurred while it was either raining or damp outside. Dealer now has vehicle in their possession and confirmed a faulty component that is on backorder with no date. Truck has had multiple other electrical issues since purchase 3 months ago. ~200 miles dealer replaced faulty HVAC module. ~4500 miles Forward collision alert as described above. Since day one there have also been Issues with trailering harness intermittently not working causing trailer brakes to not function while towing. (Yet to be diagnosed by dealer) Lastly Left turn signal would stick causing turn signal to stay on until manual deactivation. Dealer confirmed faulty turn signal and is in the process of replacing while it is in for service.

Overly sensitive automatic emergency braking/pedestrian warning. System would alert with lights and audible warning for no reason driving at ~55mph. While turning around in a Michigan left turn, system went off and brakes applied abruptly until I was at complete stop. No vehicles or persons were in front of me. There was a car following closely behind which almost hit me. Fast forward a few weeks later and now forward collision system inop light illuminated on dash and will not go off.

The theft alarm has gone off five times since I purchased the vehicle in September, dealership has been noted and has been in there for it and still goes off. Display screen froze up and did not reset until I was done driving and the vehicle was turned off for a while. The crash detection light came on and vehicle stopped itself with nobody in front of me or anybody coming towards me. The dealership has had the car for two weeks now, and they say there’s still no fix for it.

Vehicle only two months old with 2000 miles. Service engine light and brake assist service light activated. GMC dealer states brake master cyclinder failure and vehicle should not be driven. Vehicle left at dealer while awaiting replacement master cyclinder. Unknown if this is a widespread problem causing brake failures in GMC and Chevy new model Canyons and Colorados.

Blind spot warning system continues to illuminate when traveling on two lane roads with no objects in the blind spot(false positives). Especially the passenger side. I continue to be distracted while driving to check the mirror to see what is there, nothing. Then while traveling on multi-lane highways, both sides will sometimes not illuminate when there is a vehicle present in the blind spot. Both of these examples also happen more often after dusk or during dark/cloudy days. I have not taken into dealer yet for repairs but will soon. No system warning of malfunction on dash, just the false positive lights on side mirrors.

1/9/2024

Blind zone detection system and door latch system failures. The blind zone detection system is inconsistent and at times remains on with bright lights impairing the drivers ability to see at night. With this inconsistency the driver cannot rely on it properly detecting vehicles within the blind spot. Another known issue is the inability to put down windows with the drivers side door. The alert for this is to service the door latch system which typically comes on while driving the vehicle. This limits the driver being able to safely respond to traffic stops from emergency personnel as well as the ability to evacuate the vehicle through the window if necessary. The dealers that have reviewed these issues say they cannot replicate or fix them.

While slowly driving, like when parking or trying to park vehicle in garage, it will randomly surge when almost at complete stop forcing vehicle to lunge forward requiring operator to apply quick additional firm braking. It almost feels like vehicle is creeping in 2nd gear and decides to downshift into 1st gear just before coming to a stop and engine applies slightly more throttle. I have almost hit garage wall and other vehicles in parking lots due to this issue. Again, it is intermittent but is alarming when happens. I have not had vehicle in for repairs yet but concerns dealer will not be able to duplicate. No warning lights on dash for this issue.

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.

While driving to work today in fog, the vehicle auto headlights sensed enough light and turned off. Because it was foggy outside I did not feel safe only driving with DRLs on so I attempted to turn on the headlights using the touchscreen controls. The headlights would not turn on. I have video evidence of the headlights not responding to the touch controls and remaining off despite trying to turn them on.

GM is pushing updates over the air that are permanently disabling the backup camera by damaging the camera control module. Not sure yet how long we’ll have to wait for the part. I’ve heard of many that have been waiting months. They should not be pushing out defective software when it takes out the safety equipment.

The contact stated that upon activating the defroster during cold winter weather, he became aware that the defroster failed to properly defrost the front windshield and that the windshield wipers failed to adequately remove ice debris, potentially compromising windshield visibility. After a visual inspection of the windshield, the contact observed that ice had damaged the windshield wipers. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The failure mileage was 3,000. The contact stated the vehicle was taken to the dealership on 12/14/23. They did a full check on the vehicle and could not fix the issue. The dealership also were unable to find any information about a potential fix from the manufacturer.

The screen in the Truck doubles in picture, freezes and/or shuts down completely. This leaves you with out control of your GPS, radio, blue tooth, head light control and backup camera. Research on the internet has proven this seems to be an accruing problem in this truck, with some even losing their speed information. So far it has resolved itself after a while on its own, thankfully, but each time it happens the black out is lasting longer. In order for the dealership to recognize this problem we must drive to them when its occurring, which hasn't been possible. Owning this truck for 2 months and the issue of losing the computer system has occurred 4 times, this vehicle is not a daily driver.

The AC does not work properly. I constantly have to dial the temperature to be comfortable. I sometimes take my eye off the road to do this temperature adjustment. The GM dealer has tried various fixes but the temperature control is still a problem.

The roof of the vehicle crackles and pops when it is in the blowing section of an automatic car wash. We have never had any experience like this before. The roof of the truck is so flimsy that it was actually dented by the hard blowing of air. I don’t feel like this car is solidly constructed and safe.

After each rain or hand car washing, the OEM sunroof has a gurgling sound when driving at speeds above 25 mph. This does not clear for miles, or over time (at least 1 day without water). Water appears to be passing through the seal into the drainage gutter, but not completely draining out through the drains. Its been in service twice to have the drain lines cleared, and the issue remains. This has been present on other car manufacturers as a "wind pressure issue" where the force of driving causes wind pressure to push what water hasn't drained back up into the sunroof. Fix was extending the drain lines at output. GMC unable to repair.

Subject: Urgent Safety Concern Regarding 2023 GMC Canyon Fuel Pump Module Failure I am writing to express my concerns regarding a significant safety issue I experienced with my 2023 GMC Canyon, which has only 3,000 miles on the odometer. On November 12, 2024, while traveling southbound on Interstate 75 in Florida, my vehicle unexpectedly lost all power. All electronics, including the dashboard and display screens, shut off, and the engine stalled. I was forced to coast to a stop on the shoulder, directly on the bridge section of I-75 over U.S. 301. With less than 12 inches of clearance between my driver’s side and passing traffic, this situation posed a severe risk to my safety. To make matters worse, the tow truck driver was unable to safely and properly secure my vehicle due to the danger presented by the high-speed traffic. My vehicle has now been at the GMC dealership for seven days, and I have been informed that the issue was caused by a faulty fuel pump module. I believe this represents a critical safety defect that warrants immediate attention and possibly a recall. Upon further research, I have found similar reports of fuel pump module failures in online forums, indicating that this may be a widespread issue affecting other owners across the country. In addition, when the tow truck dropped my vehicle off at the GMC dealership, after reading the engine codes the dealership found 18 active engine codes. I feel as if this is a possible known issue and I should have been informed when purchasing the vehicle. I kindly request your assistance in addressing this matter. I urge GMC to investigate the extent of this defect and take appropriate action to ensure the safety of all affected vehicles and their drivers. Thank you for your prompt attention to this urgent matter. Please let me know how GMC plans to proceed. I am available to provide additional information or documentation if needed.

The contact owns a 2023 GMC Canyon. The contact stated that while at a car wash, there was an abnormal sound coming from the roof. The contact inspected the vehicle and noticed that there was a dent in the roof panel. The vehicle was taken to a dealer where it was diagnosed and repaired under Customer Service Program: 23-NA-209. After the repair, the vehicle was taken to the car wash and the same failure occurred. The vehicle was taken back to the same dealer where it was diagnosed a second time and the contact was informed that the repair could not be performed because the part was not available, and to report the failure to the NHTSA Hotline. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 1,800.

The pre-collision warning and the lane keep assist are disabled while driving frequently. It does this on its own. I have had into the shop one other time for the same thing. It’s happening more frequently now. Current mileage is 25,153. Also the personal settings on the dashboard reset on its own every five or so key cycles. Obviously there’s some kind of software problem.
