Brake System, Hill Assist, Service Advance Trac, Pre Collision Assist Issues

[BroncoInMaine]

Hello! I am looking for commiseration/advice/guidance. I have a 2021 Bronco Badlands that I purchased in December. Since then, it has been at the dealership for repairs for a total of 23 days; with three separate attempts to fix what I assume are electrical problems. It is currently at the dealership. At this point, I don’t think that the dealership is capable of fixing it. The codes are: Service AdvancTrac, Check Brake System, Hill Start Assist Not Available, and Pre-Collision Assist Not Available. Anyone else having these issues? Any thoughts? Are these issues widespread, or did I get a lemon? Thanks in advance for any thoughts.

Thank you for sending this thread! For clarification, my issue happens when the doors are on. I haven’t taken them off yet.

Had the same warnings on an F150. The issue was a front wheel hub that gave erratic signals to the ABS system. Best of luck to you.

Any answer to the issue? I have the same problem.

The last fix seemed to work (knock on wood!). I haven’t had a problem since June. They replaced the RCM (restraint control module).

I have a '22 Bronco Badlands Sasquatch 2.7L that had this same exact problem. Dealership service department held for a few days to work on the issue. Said that a cable connector was loose and unplugged near the passenger side. They said they plugged the cable back in.
Then the problem has not reoccurred ever since then. I'll continue to watch and monitor.

Had the same issue. Has not recurred since the dealership reprogrammed the ABS module.
