2022 GMC Canyon

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. 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.

At first start the first gear slips this has been going on for 2 years. Is been serviced 3 times and no one seems to know what the problem is. The services tech did discover the issue but couldn't figure out what the problem is. I only have 19,000 mile and its on warranty I'm hoping this matter can be resolved.
