2022 Chevrolet Traverse

The vehicle started throwing an error stating 'shift to park' after putting the vehicle in park. When attempting to turn the vehicle off it will not allow it, just keeping up the shift to park message on the dash. I am then unable to lock the doors. This could kill my battery as the engine eventually turns off but the lights stay on. Furthermore, leaving the vehicle unlocked and on for some time puts it at risk of being stolen. It does not happen every time I turn the vehicle off. I have tried shifting it back and forth between drive and park and sometimes that corrects the issue. I just got this vehicle about a week ago and it has not yet been diagnosed or seen as this problem just began last night. There were no other issues experienced yet. Googling it, seems to be a common issue with many Traverse owners, stating that it is typically the transmission shift control module. I do plan on following up with the dealership asap.

The contact owns a 2022 Chevrolet Traverse. The contact stated that while parking the vehicle, an error message stating that the vehicle was not in park was displayed. In addition, the contact stated that the computer did not recognize that the gear shifter had been shifted into park(P). The contact stated that it was a known failure with similar vehicles. The vehicle was taken to the dealer, where it was diagnosed with a failed gear shift control unit. The contact was informed that the gear shift control unit needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 22,168.

Both the front AND REAR exhaust pipes are cracked and broken with holes in them where the SINGLE bracket that secures both pipes mounts. There was special coverage issued to repair, but the special coverage only identifies the front pipe. The rear pipe is essentially dangling from the upstream catalytic converter, which also appears to be cracked due to the same underlying issue. If the vehicle doors are open, exhaust fumes will enter, rather than be expelled to the rear of vehicle. This pipe can essentially finish cracking and fall off into the roadway. The check engine light did not come on until these components broke. The problem is vast across many of these vehicles as reported to me by an owner of an independent service center as well as technicians who work at certified GM dealerships. The vehicle is available for inspection upon request. I currently still drive it, but its just a matter of time before a heaping hunk of metal pipe falls onto the roadway and causes an accident. The rear pipe is almost completely separated from the remaining exhaust pipe between the upstream and downstream catalytic converters at the bracket location before the flex pipe.

On Friday, 12/19/2025, I started by car and noticed that the infotainment display was taking longer than usual to boot up. It cycled through the Chevrolet splash screen 2 times until it ended on the "Update Failed. Returned to dealer." Due to this message on the infotainment display, there is no sound coming out of the speakers which results: *unable to hear turn signals when they are activated, *the front camera is no longer working, *unable to hear the parking assist when in reverse, *OnStar is no longer working, and *unable to hear front collision warnings. The display just cycles this message. I called around to several dealerships to see if I could get in that day to get this corrected. I was able to take it to a Chevrolet dealership on Tuesday, 12/23/2025, who diagnosed the problem as software corruption due to the over-the-air update and will result in a new radio needing to be installed. I then called Chevrolet Customer Service Center who stated that since my vehicle is outside of the bumper-to-bumper warranty, regardless of their over-the-air update causing the problem, I would have to pay for the repair. I asked, how do I know that this won't happen again with the new radio? They suggested that I have the dealership turn off the automatic over-the-air updates.

When I shift my car into park and turn off the engine, an error message appears-"Shift to Park." Although the dashboard displays that the vehicle is in park, the radio and lights remain active & I am unable to turn off my car. To resolve this issue, I must restart the car and cycle through park, reverse, or neutral before attempting to shift back into park again. It often takes multiple attempts to eliminate the error message. My Traverse is currently at the dealership, where I have been informed that it needs a new shifter, which is not covered under warranty. These vehicle is garage kept, one owner & has less than 32k miles on it- I have also discovered that this issue is recognized by GM, with numerous complaints documented on this site alone. Given that this is a widespread problem affecting many owners, it seems unreasonable for us to shoulder the expense of this repair.
