The car makes a clicking noise when I make sharp turns, most co.monly to the left. It is brand new with only 2320 miles on it. The noise started within the last few weeks. The rear breaking system locked up the brakes and turns the emergency break on, when backing up, even if nothing is behind me. Once it was rain drops dripping off of the rear window. Another time, nothing was there. I had to assume that it picked up a shadow in the driveway.
