Reading through this thread I think there are two separate issues, both of which I have/am experiencing.
1. The dash cluster rebooting when trying to view trailer tire TPMS menu. The cluster reboot was initially fixed via a TSB and complicated six hour set of processes to be done by Ford. Even after the TSB update is done those of us who have actually installed a trailer tire TPMS/trailer backup camera kit still have had to deal with hyper annoying bugs like having to re-run the tpms setup menu every time you restart the truck, or even hit any steering wheel buttons, etc.. Over time, this entire issue has now been fixed with an OTA update, rendering the TSB unnecessary. I have been patiently waiting and trying to force the update but hasn’t happened yet. This has all been covered in much detail in a different
thread.
2. Apple CarPlay does not run stable on the infotainment screen. It will lock up, completely disappear and default back to the Ford Sync menus, etc. I have noticed this is very consistent behavior when running the truck for an hour or more. Short trips around town thirty minutes or less I rarely ever have issues. But go on a road trip and happens almost every time. It’s very noticeable when CarPlay completely crashes, but I’ve noticed At least recently it seems to lock up (Apple Maps freezes) and then audio starts to cut out before crashing. Sometimes CarPlay will eventually come back, other times I have to restart the truck or force reboot the infotainment (hold radio pwr button and fwd seek button together for 3 seconds). This produces a loud crackling noise. Sometimes this brings CarPlay back, even if only for a few minutes. I haven’t noticed a pattern on the CarPlay crashing related to external temperature, wired vs wireless, which apps are running, etc. it seems to persist through all use cases.
Does anybody have info on problem 2?
