2023 GMC Canyon

Blind spot monitor system continues to give false alerts when no vehicles, objects or other items within blind spot area. Warning light will sometimes stay on for many miles and will go off when I pass another vehicle then go back on when nothing in blind spot again (opposite of design). System will sometime not activate when vehicle is in blind spot. See video. Dealer and GM involved, had PIT6103 performed, replaced all switches April 19, 2024 except for driver door. Issue seemed to improve but has returned and even worse that originally. This has become a safety concern for me as I will apply turn signal, look in mirror, over shoulder but then as I start to switch lanes, the mirror light will start blinking and alerting me there is something in blind spot when there isn't anything there. Causes me to abruptly swerve back into my original lane causing potential dangerous situation. Truck at dealer 12/10/2024 for same issue, dealer and GM tech service states vehicle operating as intended. Was told to either turn system off or live with it. I have multiple videos but unable to upload them here. Please contact me for more info.

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 when applying the brake pedal, the steering wheel would begin shaking. The computer on the center council that displays information, had blacked out. The vehicle was taken to the dealer who diagnosed that the brake pads had failed. The dealer had completed a software update for the main computer however the failure persisted. The vehicle was not repaired due to the brake pads (Part Number 87850375) not being in production for repairs. The failure had become more persistent and now the brakes have failed. The dealer was contacted and confirmed that the part for the repair was unavailable even for purchase. The parts were on national backorder. The vehicle had not been repaired. The manufacturer was made aware of the failure by the dealer and the manufacturer confirmed that the part was unavailable. The failure mileage was unknown.

Continues to give false alerts even on single lane roads or will not detect vehicles at all. Intermittent issue but happens frequently. Both mirror but mostly passenger side. Becoming safety issue by not knowing if something is there or not. It flashes and alerts me aggressively when it thinks something is there and I turn on my turn signal. Been at dealer three times, TSB performed to replace driver window switch but issue still present. Dealer says they have no fix.

I use the right turn signal to make a right turn at an intersection. I proceed with the turn and begin to accelerate out of the turn, as the steering wheel unturns the right turn signal is supposed to cancel as the steering wheel straightens out. Instead of cancelling the signal, straightening the wheel when accelerating out of a right turn cause the left turn signal to be triggered and in gives three signal indications for a left turn. These left turn indications are uncommanded by the driver. The issue is repeatable. It presents a serious safety concern because other drivers are being told by the truck that you intend to do something which you are not at all intending to do. Another driver could rely on these uncommand left turn indications and pull in front of the truck and cause an accident. This issue has been raised with two dealerships, one dealership replaced the turn signal triggering and cancelling mechanism in the steering column. Both dealers ultimately told me that the issue was "software" relating and that it could not be fixed. One of the dealership claimed to have "corrected the issue with a software update." That assertion was a lie, the issue remained unchanged. This issue is a serious safety issue. The truck has a defect that puts me, my family, and other drivers on the road at risk. So far, GMC has failed to remedy the "software" issue and merely returns to me a defective vehicle.

Constant smell of coolant while stopped at traffic lights or idling even worse when the air vents are on, dealership insists it's because the reservoir cap is vented but coolant reservoir is literally a foot away from drivers window even still shouldn't be smelling coolant it's been like this since a month after purchase. Having issues now with auto braking system activating for no reason did this multiple times almost got rear ended on NY State thruway because it activated with no cars near me once it activates it causes the truck to go into a limp mode (won't go over 30 mph) and starts vibrating like it needs a tune up. The radio and digital display often dissappear for no reason can tell speed. I almost got a ticket from state trooper for unsafe stopping i explained everything and was told i could get a safety violation for defective equipment and to take it garage and drive it till its fuxed , the windows have rolled down a couple of times while it's parked and won't go back up. Headlights often flicker when driving auto low beam/high beam rarely works. Every time it goes to dealership they say they can't duplicate the problem. It's really scary when you're doing 70mph and the auto brake engages. I'm literally afraid to drive it. I have a 14 year old truck with 230,000 miles I don't smell coolant or have these kinds of issues Seems to be a lot of electrical problems going on service advisor said he saw notices for bcm, front facing camera total of 6 issues. Nothing seems to resolve issues but dealerships aren't doing anything just saying can't duplicate problem also paint is chipping every where The issues started around 5300 miles and continuing

The contact owns a 2023 GMC Canyon. The contact stated while driving at an undisclosed speed, he became aware that the defroster had failed to properly defrost the windshield. The contact also stated that because of the failure, the windshield wipers had failed to function properly after becoming frozen. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the defroster was operating as intended; however, the design was inadequate to defrost the entire front windshield. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 3,000.

Automatic Breaking System. Driving along at 25-30 mph on a snow covered road when all of a sudden alert system sounded and vehicle brakes abruptly applied putting vehicle into an uncontrollable slide. Fortunately there was no one behind and nom on coming traffic. Notified GM Customer Service, as I have a case open for other issues they claim tyhey do not have a fix for. GM's response to the sudden brake application was "OH I'm Sorry"

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.
