I am in the NY City area... It's one of the coolest features that anyone has ever put in a car IMO.

I believe the timeout is 3 minutes, if you don't touch the brake when it asks you to at the timeout it will apply the parking brake. If the car should start to move or creep forward it should automatically add braking force to immediately bring the car back to a stop without driver intervention. The car will automatically apply the parking brake if you remove your seatbelt or open the drivers door while it is activated and you don't respond quick enough to manually pressing the brake when it asks you to.

With all of that in mind I think it works very well and I have never had an issue. I use it daily.

Thanks for this. Glad to know that there will be some kind of notification before it times out. In stop and go Chicago traffic, Lord knows I'll eventually end up sitting stationary for more than 3 minutes..

The only issue I have had and this has only occured once is one time while on hold it seemed to no want to accelerate. I had a brake hold malfunction pop up on the mid display. Shuffling the car between drive and park seemed to solve it. It was in my 07' and I should mention if "hold" is initiated long enough the parking brake will become activated which you need to manually remove to proceed.

Was the parking brake engaged? Wondering if thats the reason it didn't move and since we have the AUTO button for parking brake, if that had been activated, putting it into park then drive would have automatically released the parking brake.
