I also have this issue. Mine is a 2015 Titainium and we have been having issues. Ours seem to act up first thing in the morning when we come to a stop sign on our street. The stop sign is about 20 feet from the car and it will go off but only once in the morning, if we pass it later that day it won't go off. Dealer can't seem to find out what's wrong. It goes off like your going to hit it.
