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.
