October 22, 2026 General Motors Customer Assistance Subject: Request for Reimbursement for Thermostat Repair – DTC P0128 – 2022 Chevrolet V6 – Special Coverage Bulletin #N242484760 Dear General Motors Customer Assistance, I am writing to formally request reimbursement for the thermostat repair performed on my 2022 GMC Canyon V6, which experienced a thermostat-related failure associated with Diagnostic Trouble Code P0128. I understand that General Motors issued Special Coverage Program Bulletin #N242484760 to 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.

Could not turn the ignition key off beyond the Accessory position in order to turn the key completely off to remove the ignition key. The key would stick in the ON oor Accessory position. The problem was in the microswitch button on the console shifter, the front button is pushed in to enable shifting into the PARK position. This is a safety concern due to not being able to turn off the ignition and also to not remove the key from the ignition. The repair was done by the dealer, a control unit in the shifter was 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.

The ignition key gets stuck in the ignition after shutting off the car. The key may not be removed from the ignition. The failure of the transmission shift control mechanism directly impacts the safe, mechanical operation of the vehicle's powertrain and transmission park-lock functions. The vehicle was taken to a local GM dealer and the problem was recreated. This is a known problem with the transmission shift control assembly for several model years (2020 - 2023). Also, there was a previous class action lawsuit (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.

2022 GMC Canyon AT4 Crew Cab. After the vehicle is shifted into Park and the engine is shut off, the ignition key cannot be removed from the cylinder. The key is physically locked, the steering wheel will not lock, and the vehicle cannot be reliably secured. The only workaround is to restart the engine and cycle the shifter repeatedly until the interlock releases the key. Recurring. Safety implications: operator cannot reliably power the vehicle off in an emergency, cannot lock the steering column, and may be 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. the federal safety agency-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.
