   Imagine wrapping up your errands and stepping into your GMC Acadia to drive home. You arrive and everything seems fine until you park, press the button to shut it off, and a “Shift to Park” message lights up the dashboard. Thinking you might have made a silly mistake, you double-check the shifter, only to realize it’s already in Park. It has become so rampant, has drained my battery and caused anxiety.

   UNKNOWN I’m told the micro parking switch is the problem. This is an intermediate issue. This is a well known problem with the GMC Acadias. Their times when I try to turn off the engine, I get a shift to park error message. The car will not turn off, I’m unable to lock the doors and I’m concerned that the car is not in the park position thus and fearful, it can roll away. This has been occurring more often than before.

    Shift to Park warning comes on when the car is turned off and it is in park. When we park the the car and shift the car to park and turn the car off the warning "shift to park" comes on and the electrical systems will not disengage. The radio stays on, the car can not be locked, and the doors ding loud alarms if you try to exit the car. The only fix is to sit in the car for several minutes and flick the switch under the gear shift and hope that the shift to park warning…
