Quick update: It is finally getting looked at by the service department. Dealer said () there is a TSB related to this issue, and there is a reprogramming that needs to be completed. After a little more research, I'm assuming the TSB is SSM 50951 and that the November time frame for a fix has been met. Text from the bulletin below (emphasis mine):
SSM 50951
2021-2022 Bronco - Equipped With Electronic Brake Booster (EBB) - Multiple Error Messages In The Instrument Panel Cluster (IPC) After Startup
Some 2021-2022 Bronco vehicles equipped with an EBB may exhibit multiple error messages displayed in the IPC followed by automatic engagement of the parking brake immediately after starting the vehicle with the doors removed or after sitting in the vehicle for an extended period of time with the vehicle off. The issue will resolve itself once the brake pedal is no longer depressed or the parking brake is manually disengaged. This may be due to the software within the anti-lock brake (ABS) module. This issue can be avoided by placing the vehicle in accessory mode for a few seconds before starting the engine. Engineering is working on improved software to correct this condition that will be available in November 2022. No repairs should be made in attempt to correct this condition. Monitor OASIS for updates.
