2022 Chevrolet Trailblazer: battery drain or dead battery

Filed Sep 24, 2026 · Transmission · MI

When putting the gear shift into park there is a constant SHIFT TO PARK message that plays even when shifted to park and forces the car to stay in accessory mode. This drains the battery and does not allow car to shut down fully. This is a known issue with this make and model of vehicle and GM refuses to make any changes or recall any vehicles. I will have to pay out of pocket for this repair with only 29,000 miles on the vehicle.

“Shift to Park” message came on the dashboard. Car would not change gear or go into reverse or drive. Basically stuck in Park position. Car kept peeping sound nonstop for over 20 minutes. And it drained the battery. Car would not drive. Had to have it towed to the dealership I brought it from 45 miles away. I had to pay $656.72 at dealership to get it fixed. The dealership removed and replaces the shifter assembly which cost $656.72.

I am reporting a recurring “Shift to Park” malfunction with my 2022 Chevrolet Trailblazer. When I shift the vehicle into Park and attempt to turn it off, the dashboard displays a “Shift to Park” message, and the vehicle remains in Accessory Mode rather than shutting down completely. The vehicle continues drawing electrical power and the battery drains overnight. This condition poses several serious safety risks: 1.The vehicle may not consistently detect or hold the Park position, creating a potential roll-away hazard. 2.It prevents the driver from shutting off or locking the vehicle, leading to security and electrical safety concerns. 3.If the vehicle remains powered in an enclosed area, it increases the risk of carbon-monoxide exposure. I understand this issue has been widely reported by owners of late-model GM vehicles, and appears related to a defective park/position switch or shifter assembly. I request a thorough investigation, appropriate repair, and confirmation whether this defect falls under a service bulletin or recall.

Vehicle displayed "Shift to Park" error and would not shut off. This occurs after the shifter is placed in the park position. By any standard, a defective component that prevents the car from being shut off is an extreme safety concern and needs immediate attention. Additionally, the instrument panel remains illuminated and the aux power items continue to function. This has happened multiple times and has drained the battery on several occasions.

hift to park The vehicle began to display 'Shift to Park' on the display even after the vehicle was in the park position. By shifting back out of park and back into park, but that became less effective as time went on. The vehicle will not shutdown fully when this warning is displayed and therefore can cause a battery drain condition, which can result in a safety risk returning to a vehicle with a weak or dead battery. Vehicle has only 23,478 miles. In researching to understand the problem, I discovered that there are many instances of this same issue occurring at about the same time period, as well as there being several class action lawsuits on the identical issue, which shows that it isn't isolated.

The vehicle began to display 'Shift to Park' on the display even after the vehicle was in the park position. This started periodically over a few days, but then became a regular occurrence within a week. At first this could be resolved by shifting back out of park and back into park, but that became less effective as time went on. The vehicle will not shutdown fully when this warning is displayed and therefore can cause a battery drain condition, which can result in a safety risk returning to a vehicle with a weak or dead battery. This occurred at 37 months of ownership with ~28,100 miles on the vehicle. In researching to understand the problem, I discovered that there are many instances of this same issue occurring at about the same time period, as well as there being several class action lawsuits on the identical issue, which shows that it isn't isolated. Further, the cost of this repair is a replacement of the shifter assembly at nearly $700 on a $24,000 vehicle less than 3 years old, because the failed inexpensive switch isn't repairable. Repair information is available, but the system isn't allowing for an upload of the files.
