The Chevy Malibu is displaying a “Shift to Park” message even when the gear selector is physically in the Park position. This indicates that the vehicle’s computer may not be recognizing that the vehicle has been placed in Park, which is commonly associated with a faulty or failing internal park-position sensor/switch. The issue is affecting the vehicle’s ability to shut down properly. It is necessary to turn the vehicle off and back on multiple times before the system will recognize that the vehicle is in Park and allow it to shut off completely. If the vehicle does not recognize the Park position, it may remain partially powered on and potentially drain the battery.

The car has an issue recognizing that the car is in park when trying to turn off the vehicle. A message on the dash will appear “Shift to Park”. The car has not been inspected for this issue, but it does repeatedly happen, not every time I turn off the car, but it happens pretty frequently. If I am unable to get the shifter to fully engage the computer then it won’t let me completely power down the vehicle and drains the battery. I’ve had to get a battery replaced before due to a mechanic moving my car after inspecting it for a different issue and leaving the “Shift to Park” signal on and ignoring it. This left me stranded with no battery and a mechanic denying remediation for the dead battery. Many other similar gmc models have the same issue as me.

I am reporting a safety concern with my 2021 Chevrolet Malibu that is experiencing a “Shift to Park” failure.The vehicle displays a “Shift to Park” warning message even when the gear selector is fully placed in Park. Because the vehicle incorrectly detects that it is not in Park, it will not allow me to properly turn the vehicle off. This creates a concern because the vehicle may remain powered on when it should be shut down, potentially draining the battery and leaving the vehicle unable to start when needed.This issue appears to be a known problem affecting multiple Chevrolet vehicles, yet owners are still being required to pay out-of-pocket for repairs. My vehicle has just over 54,000 miles, and the repair estimate from Chevrolet is approximately $853.A gear position detection failure is concerning because the vehicle’s ability to recognize Park is an important safety function. I am requesting that the federal safety agency investigate whether this issue represents a safety defect and whether additional action is needed to protect vehicle owners.

Car states shift to park when vehicle is already in park. It took multiple times to start car again and wiggling of shifter to get car to turn off. Car was repaired by a mechanic by replacing the transmission control and transmission shifter. Chevy is aware of the problem (which can drain the battery if not caught) but has not issued a recall only a Technical Service Bulletin. Cost to me was $569.00 for repair.

Vehicle has a repeated issue recognizing that it is in park when trying to turn vehicle off. This causes concern that the vehicle may not actually be in park, will not fully power down therefore draining the battery and leaving driver stranded, or lead to other body control module/shifting problems. This is a known issue with GM spanning multiple years and multiple models. The only official fix is to replace the entire shifter assembly with an updated version which can be a couple of thousand dollars. GM refuses to cover the cost knowing that they installed a faulty part during assembly.

The vehicle says shift to park. Even though the vehicle is in park. It then causes the vehicle power to remain on and kill the battery. I’ve seen multiple instances of this same problem on the same vehicle as mine and many other GM models. My warranty ran out in January (of course) and now the issue is occurring. I’ve been stranded with a dead battery 3 times already due to this. It’s literally a microswitch not functioning correctly to tell the computer that the vehicle is in park.

The car is constantly displaying the shift to park display on the dash after the car is placed in park. Can turn the car off with the display but the prompt stays on the display and the electrical power does not shut off resulting in battery drain unless you constantly mess with the shifter until it removes the shift to park display. My first encounter with the dealer is Monday and was told they can't work on it if they can not replicate the issue. Sometimes it goes a week without doing it so who knows. Been doing this about 3 weeks now.
