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 driverâ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.

GMC CANYON 2023 ELECTRICAL SYSTEM

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.
