I have a 2014 Fusion (used, corporate car). More often than is necessary, Sync goes deaf and I have to yell commands or wait for it to wade thru "Say 1 Call Home at Home", "say 2 Call Home at house", etc. Or it doesn't respond at all. I realize that faulty, buggy software is par for the course with Microsoft, but is there a fix? And I'm talking about when the car is not moving and the A/C is off.
