Hi - I just got my brand new xA yesterday and as I was driving it around town, I noticed that there's a drilling/clicking noise (sorry hard to describe) when I have my foot on the brake in drive. It's not there when the car's stopped in reverse. Anyone else have this problem? Know what it might be?? Thanks for all your help!

 

I have noticed the same noise inside the cabin. The clicking sound is coming from the transmission selector in an automatic. I am guessing that is what you have. All that sound is an indicator that the car is being held by the brake so that you don't shift from reverse into drive.
