Example complaints

“8 out of 10 times I put the vehicle in park I receive a shift to park alert. I have to put it in another gear several times before it recognizes it is parked. Sometimes flicking the shifter push-in piece on the bottom will work. I am unsure if the car is officially parked when I don't get this message.”
NHTSA complaint #11601190, filed 2024-07“When attempting to put my car in PARK, the car issues a warning stating the car is not in PARK, it doesn't recognize the gear shift being in park, therefore, I am unable to shut my car off or lock it up. It is a known manufacturing defect and GM refuses to cover the cost to add a bandaid to it as there is no permanent fix. This is a safety issue, and now my car is not reliable, nor safe. GM refuses to issue a recall on this.”
NHTSA complaint #11640686, filed 2025-02“When i put my car into park and go to shut the car off if starts saying put car in park even tho it is already in park. It will not allow me to fully shut car off when it says that. I usually have to put it back into drive and back into park again for it to register.”
NHTSA complaint #11629377, filed 2024-12“we have a start / stop issue with our 2019 chevy blazer . the dashboard states to put into park .we cannot turn car off with this on dashboard . why is this not a safety recall , because we have seen a lot off people complaining about the same issue . WE CALLED THE CUSTOMER SERVICE FOR GENERAL MOTORS CORPORATE , and they told us there is no recall for that . we also got a postcard from a lawyer stating there is a settlement this . what are legal options to get this resolved .”
NHTSA complaint #11663540, filed 2025-05“Shift to park message coming up on dash screen eventhough shifter was in park. Engine would not turn off. Had to shift several times for vehicle to recognize park . There was a recall on some 2019 chevy blazers and a technical service bulletin issued, but my VIN number is not on the recall list. The current mileage is 37752. I bought the vehicle new. Dealership relaced shifter control at a cost to me of $553.60. If there is a safety issue, should a recall cover all ?”
