Put vehicle into Park and push engine stop button. The engine does not shut off and shift to park light comes on along with alarm. You cannot shut off and lock the vehicle. This is a serious safety issue which GM has not issued a recall. They issued a Technical Service bulletin 19-NA-206 to dealer and requiring customer to pay for the update. This should be a safety recall. There are many complaint on file from GM customers on various models. Can you investigate this and get them to correct this safety issue.
Just started happening: on occasion, when trying to shut vehicle off, the accessory light kicks on and DIC says "SHIFT TO PARK". I have to restart the car many times and shift it from drive to park to finally get it to shut off. The issue is commonly discussed on youtube. It's the sensor/switch that tells the car it's in park…

Vehicle had known service bulletin transmission shudder and told torque converter failure for vehicle with only 57000 miles. Vehicle already had TCM and transmission control and flush services at 9,000 and 15,000 miles. GM did 50/50 split of bill since 5 year power warranty was expired. GM should be paying these entire costs to customers for a known quality issue documented in numerous service bulletins for the Traverse.
SHIFT TO PARK error comes up when park to shut down. Does not allow shutdown of the car without beeping notices. Not allowing doors to lock or driver to exit. Must be fairly common as Google shows a lot of workarounds or how to fix a clip under the shifter knob down in the console.
Drivers side seatbelt, wont stay latched. On several occasions seatbelt just released. Seatbelt button was not engaging.
Side Detection unavailable alert keeps coming and off on, when car is started. The alert comes and goes.
I see that there is a recall for the exhaust leaks on the 2019 model. But there is a service alert for all Chevrolet Traverse from 2018-2022. Why are repairs on covered on the 2019?
“Shift to Park” message displays despite vehicle being in ”Park”. This prevents the engine from being shut off.
