ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
“Engine power reduced” service message “Stabilitrack” service message “4x4” service message Vehicle is available for inspection Vehicle jerks and loses power while driving at highway speeds causing 18-wheelers and other drivers to swerve around me, vehicle accelerates very slowly while in city traffic. Intersections and traffic lights are difficult to navigate due to reduced engine power endangering myself and family, also other drivers. Vehicle erases all stored messages after a certain period of non-use. Dealer service center hasn’t reproduced symptoms. Service center technicians say nothing is wrong and releases the vehicle back to me. I have invoices of the vehicle taken in 3 times. Vehicle is currently in the service center as of 10 June 2023, for the same problems indicated above. Problem is unpredictable and occurs at random. Vehicle hasn’t been inspected by manufacturer, police or insurance representatives. Warning lamps, messages and symptoms started prior to September 23, 2022 can’t remember actual date. I have the first invoice vehicle was taken in to be serviced.

POWER TRAIN
The contact owns a 2018 GMC Canyon. The contact stated that on various occasions while driving approximately 70 MPH, the vehicle was shaking. There was no warning light illuminated. The vehicle was taken to several independent mechanics; however, the mechanics were unable to duplicate the failure. The tires were and balanced. The contact stated that the failure was reoccurred. The contact stated that after taking the vehicle back to another independent mechanic, it was determined that the transmission and torque converter needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

ELECTRICAL SYSTEM
Key sticks in ignition on accessory and cannot be removed. Service Bulletin generated by GMC. Available for inspection. Safety: with key stuck in accessory position battery goes dead in 4-6 hours, potentially stranding occupants and depending on location possibly creating a traffic hazard. Three attempts by GMC Fremont CA to repair so far. They have confirmed the problem. No warning or message.

ENGINE
At age 4 years and mileage 40,000 the engine oil coolant lines failed, causing a loss of oil. Because of the location of these lines in front of and above the front axle, the potential for oil contamination of the tire running surfaces and the brake rotor existed. Fortunately, we did not drive it any distance and were extremely cautious. In looking at the parts, which we have replaced, they show much more corrosive damage than I would have expected for the trucks age. A cursory search online revealed that this is not an uncommon problem for the gm Canyon/Colorado lines.

POWER TRAIN
When cold the transmission slips badly causing a loss of power that has caused me to narrowly avoid being struck from behind by another vehicle. The slippage can be severe. The transmission appears starved for fluid. After completely warmed up the problem goes away. It is clearly a factory defect that GM is aware of and refuses to fix.

SEAT BELTS
The seat belts are very difficult to latch. It takes multiple attempts to get the seat belt locked in. I had a mechanic check and clean the buckle but it didn’t make an improvement and replacement was recommended. I have never had a seat belt buckle fail to easily latch. I am not the first owner and this issue has been ongoing.

AIR BAGS:SIDE/WINDOW:CURTAIN, SEAT BELTS:PRETENSIONER
I was on dirt forest road that was not a trail, I went through a ditch at about 3MPH and my side airbags blew. As a result the seatbelt pre tension device was also activated and the seat heaters no longer work.

POWER TRAIN
The transmission has a rough shift from 1st to 2nd, whether it is upshifting or downshifting, and isn't always predictable. This rough shift often feels like a lurching forwards when it shifts from 1st to 2nd and from 2nd to 1st it feels like something hits me in the back and shoves me forward. The 1st to 2nd often makes me feel out of control of the vehicle and while it hasn't endangered anyone as of yet, I am concerned that it will push my into the car in front of me one day. The 2nd to 1st shift also causes me concern for how it may cause me a neck injury if I'm not always focused when I'm close to that shift point. The problem has not be reproduced by a dealer or independent service center, though I do plan to take it when I have the time in the near future. The problem has not been inspected by anyone. There are no warning lights, messages, or other symptom to indicate the problem will occur.

ENGINE, POWER TRAIN, SUSPENSION
Transmission slipped almost from start. Took three appointments and two years - If my shop foreman knew the third time, why did he not call and tell me we now know your problem. I finally got fed up and brought it in one more time. Starter from day ONE maybe 50% of time made loud bang when Bendix retracted. Shop refused to take it off!!! I checked ball joint boots. One feels like no grease in it. They 'LOOKED' at it. No answer and nothing was done. Has had 'lifter noise' since new when small acceleration. Noise rate accelerates till shift and then repeats. I'm told they don't hear anything. I am 76 and hard of hearing. Pleeeeeze - don't tell me there isn't any. Not my best day today and felt it's time to say crap is crap.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
I have been receiving the “Service Trailer Brake System” error intermittently. The only information I have been have to find around this is a defective wiring harnesses between two modules. This defect is not due to wear/tear and has been reported as a defective part on multiple GMC models. When this service error pops up it is distracting and very unsafe for driving as well as dangerous when towing as the driver has no idea of the trailer brake system is functioning properly..

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Vehicle has less than 25,000 miles. Over the last 3 days, after vehicle is put in park and turned off, the key will not always rotate back to the 'off' position, and can not be removed from the ignition. This has happened at least 6 times over the last 3 days. Managed to remove key by turning vehicle back on and driving back and forth a few inches, then trying again. Took multiple tries on some occasions. With less than 25,000 miles, nothing should be worn out... Safety concerns:The possibility that the key will completely fail to be removable, meaning that if the vehicle must be left unattended, it must be left unlocked and in a condition that it could be started and stolen or driven by a curious child. The possibility that see-sawing back and forth in a parking spot could lead to an accident. The possibility that the vehicle will have to be towed. The possibility of being stranded outside- all my keys are on one ring, if I can't get them out of the ignition, how would I open the door to the house? The problem has not yet been reproduced or confirmed by a dealer or independent service station. I will be calling to schedule an appointment. The vehicle or component has not been inspected as of yet. No warning lamps, messages, or other symptoms happened prior to the first incident. When I returned home and had an opportunity, I did an internet search and discovered that the problem is a known issue, and has been reported by others.

FUEL/PROPULSION SYSTEM
No accident to report. I wasn’t aware of the problem with the High Pressure Fuel Pump intel a week later when the noise got louder, at first I figure it was the belt drive that needed check do to it sitting in the lot do to not being moved a lot. I then took it back to where the Vehicle originally came from they where able to identified the problem quickly to do them knowing already that the truck had that problem but never went to fix the problem or to take time to figure the problem out.

POWER TRAIN
FOR SEVERAL MONTHS, WE ARE NOW CONTINUOUSLY EXPERIENCING A SHAKING AND SHUDDERING OF THE CANYON EVERY TIME THE TRUCK SHIFTS FROM 1ST TO 2ND GEAR. IT IS VERY DISTURBING DRIVING DOWN THE STREET AND THE CANYON BEGINS TO SHAKE SO HARD THAT EVERYONE IS JARRED IN THEIR SEATS EVEN WITH SEAT BELTS ON. IT IS ALMOST AS IF THE CANYON IS BEING REAR ENDED BY ANOTHER VEHICLE AS WE'RE DRIVING DOWN THE STREET. OUR BIGGEST CONCERN IS THAT IT HAPPENS ON MAJOR ROADS WHENEVER WE ACCELERATE AFTER A TRAFFIC LIGHT TRANSITIONS FROM RED TO GREEN. AS WE CLEAR THE INTERSECTION, THE SHAKING OCCURS AND AS THE CANYON REDUCES SPEED MOMENTARILY, WE HAVE ALMOST BEEN REAR ENDED. OUR CANYON IS STILL UNDER WARRANTY AS WE HAVE THE EXTENDED POWERTRAIN WARRANTY. FURTHERMORE, WE JUST LEARNED OF A GM SERVICE BULLETIN, 18-NA-355 DATED AUGUST, 2019, THAT HAS BEEN CIRCULATING. WE FOUND A COPY OF THE TORQUE CONVERTER CLUTCH SB AND IT APPLIES TO ALL GMC CANYONS FROM 2017-2019. NEEDLESS TO SAY, GM (CORPORATE AND DEALERSHIP) WANT US TO PAY OUT OF POCKET FOR A VERY EXPENSIVE DIAGNOSTICS TEST (E.G., HUNDREDS OF DOLLARS) TO CONFIRM THERE IS A PROBLEM AND THEN DETERMINE IF WARRANTY WILL COVER THE REPAIR(S). THIS IS A VERY SERIOUS VEHICLE SAFETY ISSUE THAT CAN CAUSE ACCIDENTS IF THE DRIVER IS NOT ACCUSTOMED TO BEING TOSSED ABOUT IN THEIR SEAT WHILE DRIVING THE CANYON. GM NEEDS TO DO A RECALL TO FIX THIS PROBLEM FOR ALL AFFECTED VEHICLES AS PEOPLE, ESPECIALLY THOSE THAT ARE ON FIXED INCOMES, ARE NOT ABLE TO PAY OUT OF POCKET FOR A TEST JUST TO VALIDATE THE TOQUE CONVERTER CLUTCH SHUDDER DOES EXIST.

EXTERIOR LIGHTING
AT NIGHT, THE BACK-UP CAMERA DISPLAY ON THE DASH IS SO BRIGHT, IT LIGHTS UP THE WHOLE CAB AND THIS CAUSES THE DRIVER NOT TO BE ABLE TO SEE ANYTHING OUTSIDE THE CAB OR AROUND THE VEHICLE WHEN REVERSING. I ALMOST BACKED OVER MY WIFE BECAUSE I COULD NOT SEE HER BECAUSE OF THE BRIGHTNESS. THERE IS NO WAY TO ADJUST THE BRIGHTNESS WHEN IT IS IN REVERSE AND IN THE DARK YOU CAN NOT SEE MUCH IN THE SCREEN BECAUSE OF THE BRIGHTNESS. I TOOK IT TO THE DEALER AND HE SAID THEY HAVE SEEN THIS PROBLEM ON THE FULL SIZED TRUCKS BUT NOT THE MID-SIZED AND HE SAID IT WAS IN WORKING CONDITION. I FEEL THIS IS VERY DANGEROUS IF YOU CAN'T SEE WHEN YOU ARE REVERSING.
