That's what caused me to be nearly rear-ended when this happened to me. The light changed and I hit the gas just as the 3-minute clock expired and the parking brake got set (even before the notification popped up). I actually started forward a few feet before the brake fully kicked in and stopped me. The guy behind me was caught by surprise and almost crunched my 2-day old (to me) LS!!!

 

here's a post from a few years ago. Something similar happened to Ben Affleck

Last night riding along and the Parking Break feature goes off didn't know what was happening so rode that light for 1/2 mile pulled into garage and the light was off. Let's see what happens today
