I have a 2012 Fusion Hybrid with about 65,000 miles on it. very happy with it overal. For about the past month, however, I've been hearing a chime that I cannot identify the reason for. It's driving me nuts. There is no warning message or light that I can see, and there seems to be no ryme or reason for the chiming. It's a series of 2 tones that repeat about 3 or 4 times in quick succession. It seems to me I hear it most oftem when accelerating, and usually within a few minutes of starting to drive after being parked. I've had the car serviced as required. I believe the chiming began shorty after I had new tires put on. Appreciate any insight anyone has on this. Thanks JSV
