NHTSA Complaint #11431466 — 2021 FORD F-350

An unknown electrical issue possibly sensor, module or wiring related causes several faults in the system and they appear on the dash. These faults disable many safety features built in to the vehicle and a few convenience features as well. The faults displayed are: "pre-collision assist not available", "hill start assist warning", "service advance trac" and "drive mode not available" When this happens randomly the vehicle will stop producing forward acceleration and slow down very quickly as if I took my foot off the accelerator. When this occurs it is a dangerous situation made worse at higher speeds and I must quickly move off the road without causing an accident. The vehicle has been to the dealer 4 times since new (4765 current miles) and there is no definite solution at this time.
