My wife has a 2016 CX-3 Grand Touring and the infotainment constantly reboots, between 2 and 8 times, but only on cold mornings. 2 weeks ago we went to the dealer to report it and they did a hard reset and updated the OS to the latest version. That helped for 2 days, then the issue came back. We then scheduled an all day appointment with them, for the following week, to leave the car so they can work with the Mazda tech line on the issue. Both the dealer, and Mazda, decided that they should replace the entire CMU/Infotainment screen. Which was done yesterday. Sadly, the unit rebooted 3 times on my wife's drive to work this morning... which is only 20 a minute drive. I'm not sure where to go from here. I've offered the dealer to keep the car, multiple days as long as we can have a loaner, so that the Tech can take the car home and see what it does on his ride in. But other than that, I'm not sure what else can be done. I used to work in car stereo, years ago, and to me it seems like a loose connection that makes itself present on cold days... when the wires are more brittle.
We also own a 2016 CX-5 Grand Touring and a 2017 Miata RF LE, neither of which have this problem.
Had anyone actually been able to solve an issue like this?
