After being driving vehicle will not shift into park. When shifter is moved into park position vehicle is not recognizing this and will continue to move. Gear shifter has to be wiggled around for vehicle to finally get into park or at all. Safety concerns - if vehicle is not in park mode vehicle can roll away or continue to move causing damage or injury to persons or property. Online research indicates this is a nationwide problem and there are several lawsuits against gmc concerning this issue. All instances seem to be associated with the Acadia.

Numerous occurences especially recently of shift vehicle to park when vehicle has been parked, turned off and already shifted into park position. Several occurrences where almost every time within 24 hours I use my cruise control and air conditioner at the same time my check engine light will come on as well as the stability trac indicator which then causes my air conditioner not to work and inability to start the vehicle due to having a check engine light on.

The vehicle would intermittently display a "Shift to Park" message and sound alert chiming when moving shifter to park position. The car could not be parked until the chiming and message were dismissed by jiggling the shifter, sometimes after a prolonged battery-draining attempt to end the condition.

We own a 2018 GMC Acadia Denali. Upon shifting the vehicle into park, we cannot turn off the engine. The vehicle gives us a "Shift to Park" message on the instrument panel. As a result, we are unable to shut off our engine and, to avoid the battery running out, are forced to attempt to move the shift lever in and out of "Park" to get the car to detect that the shift lever is in fact in ‘Park.’”
