I am the happy owner of a 2016 Mazda 3 GT; my third Mazda 3! My only problem has been with the heads up display and is infrequent. About one start out of fifty, the display with rise up and then immediately retreat back into its cubbyhole or sometimes it doesn't deploy at all. A restart will clear the problem. It's not a serious problem, just annoying. One time I was able to drive to the dealer's service department so they could see that the display didn't deploy. They fiddled with the settings but couldn't resolve the problem. They tell me that they have no known fix for this. Has anyone else experienced this problem and was it resolved.
