It's now June 1, 2020 but in mid-May, my Sync system seized up and would not accept a radio station change, displayed an earlier-in-the-day map location and despite a few off/on ignition cycles, wouldn't reset.

Then on 5/25, the cluster began displaying a 'Trailer Connected' and 'Trailer Disconnected' message every time the service brake was depressed.

On 5/26 I took it into the local dealer on a NHTSA -issued recall (battery cable) and of course, there were no saved DTC's nor could the tech replicate the error.

Of course...These usually only appear after the warranty runs out.

The radio station input problem recurred briefly on a recent trip so I'm going to chalk it up to satellite positioning as I 'could not replicate' the problem, either.
