2017 GMC Canyon

I was driving down the road when all of a sudden I received a warning “power steering” drive with care and something called “stabilitrack” my power steering had shut off. I was driving down a highway going about 65 around Walker lake no with turns. Coming around one of the turns the power steering kicked back on and I almost jerked off the road. The trucks power steering continues to go in and out making is extremely scary to drive. I have parked it since

The central control screen goes through a rapid, seemingly random series of "ghost touch" control changes. It cannot be stopped or shut down. It often changes the language of all screens in the vehicle (I cannot read French), shifts the instrument panel screen from speedometer to any of a large number of random screens, changes rear camera settings or deactivates it, changes bluetooth and telephone settings, and any of dozens of other actions many of which have a direct and immediate impact on vehicle safety. It serves as a terrible driver distraction because the driver has to do whatever they can to keep the screen from making unsafe changes to the vehicle settings. The driver's attention is divided between whatever the screen is doing and what is happening on the road.

The contact owns a 2017 GMC Canon. The contact stated while driving 70 MPH, the check engine warning light illuminated along with the following displayed message "ISSUE WITH EXHAUST SYSTEM REDUCE ENGINE POWER TAKE TO THE DEALER IMMEDIATELY", as the vehicle slowed down drastically not allowing the driver to accelerate over 20 MPH. The contact stated that the vehicle was towed to the dealer where the failure was diagnosed as the diesel particulate filter would not complete a burn. A manual regeneration was completed. The contact stated that the failure recurred after 2,500 miles in November 2022 and the vehicle was taken to the dealer, Kelley Buick GMC (255 W Van Fleet Dr, Bartow, FL 33830) where another manual regeneration was completed. The contact stated that the dealer informed him that if the failure reoccurred, he would need to purchase a filter for $2,000. The contact stated that the vehicle failed to inform when a burn was needed as other diesel vehicles were equipped with the burn alert system along with a switch to complete the burn. The manufacturer was notified of the failure and stated there were no recalls for the failure. The failure mileage was approximately 3,000.

The contact owns a 2017 GMC Canyon. The contact stated that while operating the vehicle, the temperature gauge would not operate and the vehicle would not properly accelerate while pressing the accelerator pedal. Also while operating the vehicle the contact had become ill with headaches and dizziness which required medical attention. Upon inspection, it was discovered that a hair-like fiber was present coming from the exhaust pipes. The vehicle was taken to the local dealer who informed that the temperature gauge and exhaust system was faulty and needed to be replaced. The hair-like fibers were not identified. The contact was concerned that the hair-like fibers had clogged the exhaust system causing carbon monoxide to enter the cabin of the vehicle. The manufacturer was notified of the failures. The vehicle was not yet repaired. The failure mileage was 52,000.

After 5 years and 2 months of ownership of this vehicle, at ~52,000 miles it began to develop a shudder in the driveline, that I originally ascribed to an imbalanced rear wheel. After checking the rear wheels for balance, that cause was ruled out. I took the vehicle back to the GMC dealer where I had purchased it new. They claimed that the cause of the problem was a defective transmission fluid that somehow became contaminated with water. They offered to flush the entire transmission and install new 100% synthetic transmission fluid for a cost of $770. When I complained about a vehicle with 52,000 miles developing transmission problems the dealer consulted with GMC, and then agreed to flush and replace the allegedly defective fluid without cost. Upon further investigation, it appears as though the origin of the issue is not due to the nature of the fluid, but rather the use of an undersized torque convertor in this 8-speed transmission, which began in the 2017 model year. The smaller size and inadequacy of this torque convertor design is the root cause of this shudder, which not only has presented itself in the 2017 GMC, but also in corresponding GMC/Chevrolet models using the same transmission. The danger of a transmission failure can have catastrophic safety consequences for the driver, passengers as well as the motoring public, not to mention a very large transmission replacement charge for the owner. There is currently a Class Action lawsuit in the State of California for this notorious "Chevy Shake."

The contact owns a 2017 GMC Canyon. The contact stated while driving 35 MPH, the vehicle failed to respond when the accelerator pedal was depressed; instead the vehicle would jerk forward. The contact stated that there was no warning light illuminated. The contact had driven the vehicle to a local dealer, who diagnosed that the transmission needed to be replaced. The vehicle was repaired at the owner's expense. The manufacturer had been informed by the dealer of the failure. The failure mileage was approximately 64,000.

Fuel/Emissions: I have a 2017 GMC Canyon; I am not able to fuel the truck without the use of a funnel. As soon as I start fueling, it shuts off and "spits gas" on my clothes. When I do use the funnel, it takes me almost 20 minutes to fuel the truck. I have read in forums that it is a common occurrence with the 2017 Colorado and Canyons. I have tried to explain to the dealer that it may have a clogged evap canister. The dealership was dismissive and said it was a purge valve. The dealership changed the valve but failed to fix the issue. I returned to let them know and was told it would be days before anyone would look at the vehicle even though I did call and was told to bring it. Two things, evap canister is part of the emissions system and is to cut down on the emissions, and secondly, the gas gets everywhere when it "spits" it out because the vapers have no where to go. This is the only vehicle my wife and I have and is a good truck. There are plenty of forums such as coloradofans.com on line where others have the same issue.
