I put my 2018 Acadia in park in my garage (a flat stationary spot) and I receive a message that states 'put vehicle in park', which it already is in park and as a result the engine won't shut off. I have had this occur several times over the past month, but most recently occurred on October 24, 2019. It is my understanding it is possibly a bad shifter assembly which not only will keep the vehicle from shutting off, it can also not hold the vehicle in park. I have researched this issue and I am disappointed to discover that GMC is aware of this issue occurring with the vehicles. This is a serious issue especially if it will fail to hold your vehicle in park.
