Shift to Park message displays on the Driver Information Center (DIC) when the vehicle has been shifted to Park and the ignition has been turned to the Off position. This causes alarm chimes to go off when door is opened and the battery to drain.

The vehicle will not shut off and vehicle information screen states Shift to park. When this happens we have 2 options. 1st to sit and wait for the vehicle to turn off(takes over an hour on average), 2nd Disconnect the negative battery connection. The vehicle shuts down nearly instantly. Then reconnect the battery before being able to use the vehicle again
