2023 GMC Canyon Reliability Report

Owners of the 2023 GMC Canyon frequently report issues with the Forward Collision Avoidance system. Common symptoms include unexpected and abrupt braking, sometimes leading to loss of vehicle control, particularly in scenarios involving snow-covered roads or when the system mistakenly detects oncoming traffic. Complaints also highlight instances where the forward collision warning light remains illuminated without apparent cause, requiring a key cycle to reset. These problems are noted at mileages ranging from approximately 2,251 to 13,000 miles. Safety implications are significant, as abrupt stops have nearly resulted in crashes, and some owners have chosen to disable the system due to these recurring failures.

Owners of the 2023 GMC Canyon frequently report issues with the lane departure and related safety systems, including false positives and system deactivations. Common symptoms include the blind spot monitoring system activating incorrectly, especially at night, and pre-collision warnings and lane keep assist disabling themselves during operation. These issues are often described as intermittent but increasingly frequent, with one owner noting occurrences around 25,153 miles. Complaints highlight safety concerns due to distraction and uncertainty about vehicle surroundings. Despite multiple visits to dealerships, owners report no effective fixes have been provided, and the problems persist.

Owners of the 2023 GMC Canyon frequently report issues with the vehicle's transmission, specifically the 8L80 model. The most common symptoms include the vehicle lurching forward or surging unexpectedly, particularly when slowing down or coming to a stop, such as when parking or approaching traffic signals. These incidents often occur during gear shifts from 2nd to 1st gear and are described as intermittent but alarming. Complaints indicate that the problem persists even after warranty service, with some owners mentioning that dealerships struggle to replicate the issue. Safety concerns are noted, as the sudden forward movement has reportedly led to near-collisions with objects like garage walls and other vehicles, posing a potential risk for buyers to consider.

Owners of the 2023 GMC Canyon frequently report issues with the vehicle's roof structure, particularly related to the sunroof and roof panel. Common symptoms include a gurgling sound from the sunroof after exposure to water, which persists even after service attempts to clear drainage lines. Additionally, multiple owners describe the roof panel being susceptible to denting and abnormal noises during car washes, with one case noting that a repair under a customer service program did not resolve the issue. These problems are reported at relatively low mileages, such as around 1,800 miles. While no safety implications like crashes or loss of control are mentioned, potential buyers may want to consider these structural concerns.

Owners of the 2023 GMC Canyon report issues with the vehicle braking autonomously without warning, even when no obstacles are present. Complaints frequently mention abrupt stops and the activation of crash alerts, with one report indicating that this has led to bodily and property damage. These issues are noted at varying mileages, including as early as 2,000 miles and at 14,129 miles. Additionally, a failure of the brake master cylinder is reported, leading to service warnings and the vehicle being deemed unsafe to drive by a dealer. The autonomous braking incidents and brake system failures raise concerns about potential safety risks, including loss of control and crashes.

Owners report sudden power steering failures in the 2023 GMC Canyon, often accompanied by a "Brake Failure" warning and subsequent limited vehicle speed. Multiple complaints describe simultaneous loss of braking effectiveness and power steering, occurring unexpectedly at highway speeds, creating significant safety risks as drivers struggle to maintain control. These issues typically arise without prior warning, and in one case, began following a remote electrical update, with failure mileage noted at approximately 2,500 miles. The sudden nature of these failures and their occurrence in high-speed traffic situations pose a risk of accidents, as drivers report narrowly avoiding collisions. Buyers should be aware of these potential steering and braking issues, especially given the difficulty in reproducing the problem for diagnosis and repair.

Owners of the 2023 GMC Canyon report issues related to the visibility and wiper system, particularly in cold weather conditions. One complaint describes the defroster failing to effectively clear the front windshield and windshield wipers being unable to remove ice debris, leading to impaired visibility. This issue is noted at approximately 3,000 miles, and the owner mentions that a dealership was unable to resolve or find information on a fix. No crashes, fires, or loss of control are reported, but the visibility impairment could pose a safety concern.
