2022 Chevrolet Trailblazer power train problems

“When using the gear shifter to put car into park, it does not register that the car has been parked at all. It is available for inspection upon request. The car says it was in park but had to use the parking brake to ensure the car was parked. The manufacturer has been notified of the issue and even settled a class action lawsuit regarding the issue without issuing a recall.”

“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.”

“When I shut off the engine, it says “Shift to park” and the car will not turn off. To get it to turn off, I have to turn the car back on (usually multiple times), until it recognizes that it IS in park.”

“I was driving down the highway when the 3 bolts holding the exhaust under the car broke off. My exhaust was dragging down the highway until I could safely get pulled over. The bolts are welded in of course so you can’t just put new bolts in you have to replace the whole catalytic converter, which is a pain to do unless you take it to the dealer and pay $2000.”

“The car showed an error message saying shift to park when trying to turn the car off. The car was in park and showed in park on the dashboard & shifter but the error message still said it wasn’t in park. While this error is showing it will not allow the car to shut off or lock doors. I have a little over 19k miles on this car and should not have this issue. After researching this has been a know issue with their vehicles for years and it still has not been addressed.”

“Vehicle stalled and shut off while driving in moving traffic on multiple occasions, resulting in sudden loss of power steering and brake assist — a significant safety hazard. Battery failed at 32,860 miles (September 2025) with all low voltage codes. Battery replaced by dealer. Vehicle continued to exhibit stalling, no-start, and Battery Saver Active warnings.
