My 2021 Mach 1 has an intermittent issue with Sirius XM. The traffic data only loads about 40% of the time and the satellite radio doesn't come back on about 10% of the time when I stop for a short errand. AM/FM/external sources still work; it's just the satellite that won't come on. I can "fix" it temporarily by pulling the amp fuse (#25 in the passenger footwell) but that works only until the next time it chooses not to come back on. My local dealer replaced the APIM after it showed as failing some diagnostics, but that didn't solve the problem. I'm looking for any suggestions to help keep the dealership from easter-egging the issue.
