In the Mustang Mach-E, SYNC 4 "was so buggy that the handlers hovering around the car kept stopping people from tapping the screen. The only place people could try to interact with Sync 4 was at a single standalone kiosk in the next hangar over, which — along with the rest of the event — closed a little more than one hour after the onstage action wrapped up." That was during the during the global unveiling and it doesn't help that Sync problems like this and other extend to production vehicles that have been on the road for many years. Should we be concerned? Has anyone here tried the infotainment system out for themselves?
