I have a 2023 Ford Edge and my sync 4 system keeps rebooting randomly while I am driving. I thought the APIM was the issue so I bought a used one same part no. with lesser miles and installed in mine but the problem still happened once after i did the isntall. Did all master reset and also got it checked at ford dealership they said there’s nothing wrong since it didn’t happen while I was there. Please any help is greatly appreciated.

Ford is well aware of the issues…
so basically no fix?
Not yet.
do you think swapping the sync module with another one probably a different part no. could fix this?
No, this is a software issue…
