2022 Chevrolet Colorado Powertrain & Transmission Problems

I purchased the vehicle in October 2021. Through the 2021/2022 Michigan winter - no issues. This 2022/2023 winter, an issue has occurred. When breaking, prior to coming to a complete stop, the vehicle shifts down hard with two clunks. On a slippery surface, it causes the truck to slide a bit - as though the wheels are close to locking-up. I took the truck to Art Moehn Chevrolet in Jackson, Michigan. They received a letter from GM stating this is normal. See attached. This problem only occurs in freezing temperatures and when first driving the vehicle. In warmer temperatures, or after the truck has warmed up in freezing temperatures, the problem lessens or goes away.

The contact's partner owned a 2022 Chevrolet Colorado. The contact stated that upon placing the vehicle into park, he went into a store while his partner remained in the vehicle with the engine running. The vehicle began to roll back as an abnormal, whining sound began to emit from the transmission. As the vehicle began to roll over a curb and into some grass, the passenger attempted to exit the vehicle but was unsuccessful. The vehicle continued to roll back as the vehicle into the telephone pole which caused the vehicle to come to a stop. The air bags did not deploy upon impact. The contact stated that the air bag, seat belt, and the service safety restraint warning lights appeared on the instrument panel. The passenger was taken to the hospital by ambulance where she was treated for a head and neck injury. A police report was filed. The contact was able to secure the damaged front passenger side door with a bungee cord and drove the vehicle home. The manufacturer was notified about the failure and a report was filed; a resolution of the failure had yet to be determined. The vehicle had yet to be diagnosed for the cause of the failure; however, upon investigation, the contact believed that the failure was the result of a park to reverse defect. The vehicle had been deemed a total loss by an insurance adjuster and was destroyed. The failure mileage was approximately 7,950.

Unknown on first appear - key gets stuck in the ignition. This happened for the first time shortly after we bought it. It was still under warranty and the Chevrolet dealership in Washington PA fixed it. We paid to have it fixed and now it’s out again and we can’t get our key out of the ignition and we sit there forever trying to get it to work. Restarting vehicle etc. We had an appointment the other day and sat there well over a half hour trying to remove the key from the ignition because you obviously can’t leave it in the vehicle. We even drive the vehicle to a different spot in a lot to see if it will release what seems to be pressure to get it out? There’s no warranty to fix it and we shouldn’t have to replace the same issue over and over again. I feel this should be a recall or a lemon issue. Also- we took our vehicle to a local inspection auto shop because we have an issue with the transmission shuttering like you are driving over a rumble strip. We were informed there has been recalls on the Colorado trucks through the years however we have no recall on our vin. I believe and feel this should be covered under the recall since it’s obviously is an ongoing issue through the years. There weren’t any warning lights and currently still no warning lights when these issues happen. This is a big inconvenience owning a truck that we bought brand new and having repeated issues that are known for this particular vehicle. Yes it will be available to be inspected upon request. Please assist. Attached is a receipt where we tried to see if the truck was possibly shuttering from being out of aligned. That wasn’t the case and they referred us to Middle Creek Garage where we paid to have it looked at and they told us about the transmission recalls and what they are known for. I can’t find my receipts. Washington Chevrolet in Pennsylvania is who has worked on our ignition key issues twice. Your date below is messing up. Transmission started in 09/2025.
