ELECTRICAL SYSTEM, POWER TRAIN
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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: BLIND SPOT DETECTION
The automatic emergency braking system on our 2023 GMC Canyon engaged suddenly 3 separate times while we were driving at around 50 MPH on a clear, straight road with no obstructions. We brought the truck to the dealership the next day, and the service department said it was a software issue and reprogrammed the truck's computer. This did not fix the problem, and we experienced the same unexpected automatic braking while driving at 50 MPH on a clear road. We brought the truck to the dealer again, and it has remained there ever since. This poses a risk for sudden unexpected stops, loss of control of the vehicle and rear end collision. There were no warning lights to indicate a problem. In addition, the blind spot indicator light on the drivers side starts blinking when there is nothing in the blind spot. We first notice the problem July 23, 2026 and it recurred on August 6 2026.

POWER TRAIN
The contact owns a 2023 GMC Canyon. The contact stated that while driving approximately 15 - 20 MPH, the message to decelerate immediately was displayed on the instrument panel, and the transmission unexpectedly downshifted to 1st gear. The failure had occurred several times, at times while driving 75 MPH. The vehicle was taken to the dealer to replace the valve body and solenoid. The second time the vehicle was taken to the dealer, it was determined that there was a failure with the transmission caused by an inoperable wiring harness connection. The vehicle was repaired. The failure persisted, and the vehicle was taken to the dealer a third time but had not been diagnosed or repaired. The manufacturer was not made aware of the issue. The failure mileage was approximately 42,000.

ELECTRICAL SYSTEM, POWER TRAIN, UNKNOWN OR OTHER
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.

POWER TRAIN
With 94 Miles my brand new GMC Canyon AT4 I leased had a catastrophic failure while i was driving it, the front axle essentially exploded. The findings were that their was no oil/lubricant installed in it from the factory which made this happen. I now have to wait many months for the dealership to repair my vehicle while i have a "loaner" with a bunch of restrictions on it. And i have to pay my lease the entire time it is being worked on because of a factory fault. If i had been going more than 25 mph this would have resulted in a crash/injury.

ENGINE, UNKNOWN OR OTHER
Coolant leak observed at the upper radiator hose quick-connect fitting. The leak appears to originate from the internal seal at the radiator inlet connection. This issue developed without warning and is consistent with a known defect in the radiator hose seal design used in 2023 GMC Canyon vehicles. Vehicle experienced coolant loss and visible residue at the connection point. No visible external damage to the radiator or hose assembly was observed. GM has issued a Special Coverage program for similar radiator inlet hose seal failures in related vehicles using the same component design. Concern is that this defect may lead to coolant loss and potential engine overheating if not addressed.

SERVICE BRAKES
I first noticed the brakes squealing in August 2025 at 15,000 miles. The dealership said I needed to resurface the front rotors. I mistook this a coating and brake debris, but it was actually the rotors warping. By 21,000 the vehicle is pulsing heavily when stopping. I went back to the dealer and this time they told me all 4 rotors are warped. GM denied coverage of the pads and rotors. Normal driving, no collisions or towing.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, VEHICLE SPEED CONTROL
On [XXX], at approximately 4:10 PM, I was at the McDonald’s drive-through located at [XXX] and [XXX] in Springfield, Missouri. I was stopped at the final service window. As I pulled away from the window, I approached a 90-degree left turn heading south. I removed my foot from the accelerator pedal to allow the truck to coast slowly around the corner, as the area is heavily pedestrian and requires caution. While coasting with my foot completely off the gas pedal, the truck suddenly and rapidly began to accelerate on its own. I immediately applied the brakes, and the unintended acceleration stopped right away. At that point, I called Thompson GMC in Springfield, Missouri, at 4:17 PM to report the incident. This was the second time this has occurred. The first incident happened several months ago on [XXX] north of Strafford, Missouri. While navigating a curve, I lifted my foot off the accelerator to coast, and the truck again experienced sudden, hard acceleration. I quickly applied the brakes, and the acceleration stopped immediately. I called Thompson GMC at that time as well. They advised me that I could bring the vehicle in for inspection, but without a check engine light or warning light illuminated, and without the issue occurring while a technician was driving, it might be difficult to diagnose. I did not bring the vehicle in after the first incident. Yesterday, a Thompson GMC employee scheduled an appointment for me to have the truck inspected. No warning lights or check engine lights were illuminated on the dashboard during either incident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
