What is your shutdown sequence? Is your foot on the brake pedal? Do you use the auto-hold feature all the time? Do you apply the parking brake before you shut down the car or let the car apply it on its own?

The rear parking brake with automechanical actuation is used for a lot of things, including auto-hold, short-term false “Park” when left idling for a long time until the transmission truly engages Park several minutes later.

All of these things can be and often are audible and felt.
