GMC Canyon Electrical problems by year

address a known thermostat issue affecting certain vehicles. The program provides extended coverage for the engine coolant thermostat and its housing for up to 15 years or 150,000 miles from the vehicle's original in-service date, subject to the program's eligibility requirements. The issue I experienced is consistent with the condition addressed by this program. The P0128 diagnostic trouble code indicates that the engine coolant temperature is not reaching the expected operating temperature within the specified time, which can be caused by a malfunctioning thermostat. This is the type of failure that the special coverage program was established to address. Unfortunately, I incurred the expense of repairing this condition out of pocket. Had I been aware of the applicable special coverage at the time of the repair, I would have sought assistance through an authorized Chevrolet/GMC dealership before paying for the repair myself. I respectfully request that General Motors review my repair documentation and consider reimbursing me for the costs incurred. The existence of Special Coverage Program Bulletin #N242484760 demonstrates that GM has recognized this thermostat issue and established extended coverage for eligible vehicles experiencing the condition. I believe it is reasonable and fair for GM to review my claim in light of the nature of the defect, the diagnostic code involved, and the purpose of the special coverage program.

to turn it back on. Third time, my other son was driving. Arrived at his destination and when he was about to leave, the vehicle did not turn on. It was completely dead. The battery was good but all the electrical systems were dead. I had to tow the vehicle to the dealership. They changed the fuse box and that fixed the issue. It is dangerous because the vehicle can shut off anywhere at any time. Safety issue. Issue #2: Oil leak. The vehicle is a 2016 Canyon. It has about 76,000 miles on it. An oil leak was found in the engine. Had to take it to the dealership to fix it. Another high expense and repair. Issue #3: Power steering. While driving in the city, I got a warning saying that the power steering needed service. The wheel became extremely hard and it was difficult to steer the vehicle. I was able to bring the vehicle to a parking lot near to where the issue occurred but had to use a lot of strength to steer the vehicle to safety. I can not imagine what would've happened if I was driving on the highway or in a busy street. Apparently there is a recall for the 2015 vehicles but not for the 2016 even though it uses the same system and parts. Lots of complains online from 2016 vehicle owners reporting this same issue. Cost to repair the issue: $3,500 out of pocket. Issue #4: Media screen. The media screen keeps failing. This is the second screen installed by the dealership and it still have the same issues. At times it got black.

replaced to correct the problem. Part cost was $525, labor was $225.73. This is a class problem on Chevrolet Colorado and GMC Canyon trucks. There should be a recall on this problem.

eventually rolled to a stop. The Forward Collision Unavailable warning message and Check Engine light then illuminated. The contact activated the hazard lights and drove at 5 MPH to a nearby parking lot. The contact stated the brakes continued to malfunction, requiring the driver to allow the vehicle to roll to a stop. The dealer was notified of the failure and confirmed there were no open recalls associated with the VIN. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 39,000.

(Jefferson & Riley class action settlement) which specifically covered a predefined list of early-generation model years (including the 2017-2019 GMC Acadia, 2019 Chevy Blazer, and 2016-2019 Malibu/Traverse/Volt). GM continued using similar microswitch shifters in newer vehicles like your my 2022 Canyon. I had no prior warning lamps but the symptoms occurred infrequently after I purchased the vehicle on March 29, 2023. I am the original owner of the vehicle and in July 2026 the problem became frequent - on an almost daily basis. I took the vehicle to my local GM dealer and I was initially told to use my spare key and see if that fixes it. In August 2026, I took it back to the GM dealer and insisted that a diagnostic be done, at which time they agreed that the transmission shift control assembly was faulty. My concern is that GM continued to use the same defective part in newer GM vehicles even though this part was previously determined to be defective in the Jefferson & Riley class action settlement.

making this issue, that I would have to continue driving the truck and bring it in to the dealership with the power steering and StabiliTrack warning. According to the technician, they can't do much due to that they don't know what is causing the power steering to malfunction. I haven't been able to take it to the dealership because the warnings have occurred while I'm far away from a dealership or diagnosis area. Also, I will not risk my safety maneuvering a vehicle that has lost electric power steering around a city where lots of left or right turns are necessary to drive to a locality. This is the only vehicle I have to go to work or travel and fear for my safety when this happens. PLEASE HELP.

forced to leave an unattended vehicle in accessory mode - fire, electrical, and theft risk. The defect is documented in GM's own literature. GM Bulletin PI1429 and GM TSB 19-NA-206 address this exact symptom on the Canyon/Colorado platform. NHTSA-archived GM TSB MC-10113734 (March 2015), "Ignition Key Cannot Be Removed and/or Does Not Rotate to the 'Off' Position," names the 2015 GMC Canyon and Chevrolet Colorado. The 2022 Canyon uses the same shifter and ignition-interlock architecture. Documented cause: failure of the transmission control lever microswitch that signals "Park" to the interlock solenoid. Documented fix: replace the shifter assembly. Reported to an authorized GMC dealer while still under the New Vehicle Limited Warranty. Dealer recorded the concern verbatim - "key stays locked in ignition when shifting to Park" - and closed it "unable to duplicate," no repair, despite the open bulletins. A second GMC dealer later refused to inspect, with the service advisor stating on the service drive that there is no fix, that they see this on Canyons and Colorados all the time, and that he had seen another such vehicle the day before. No diagnostic, no repair order. GM's Technical Assistance Center has since taken the position that the bulletins above do not apply to this vehicle, which is inconsistent with the bulletins themselves. No crash, no injury, no fire. Reporting a manufacturer-documented ignition-interlock defect GM is refusing to repair.
