Sierra 2500

  • miles
The vehicle will be in the park position and a warning on the dash will say shift to park not allowing you to shut off the vehicle. Jiggling the shifter sometimes works but often have to restart the vehicle numerous times to get the error message to not appear and be able to proceed with shutting off the vehicle
