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.

Appreciate your reply.
I have tried numerous sequences in a quest to isolate the problem. I cut the ignition first with the brake pedal on and with the brake pedal off; I applied the parking brake before cutting the ignition, and I tried the various sequences with the auto-hold on and off before cutting the ignition. I concluded that ignition cut-off, with or without the presence of the foot brake, parking brake or auto-hold, was the initiator of the problem sound.
