NHTSA Complaint #11676334 — 2021 FORD BRONCO

While driving and completely randomly, multiple critical errors appear on the display, and vehicle goes into limp mode. The errors is play in order as follows: 4x4 Off -Service Vehicle Soon -Service advance Trac -Check 4x4 -Pre-collision assist not available -Service advance track After the errors appear, the vehicle goes into limp mode, no longer being responsive to the accelerator pedal. After putting the vehicle in park and turning it off, then restarting, the vehicle works with no errors. After 5 or so minutes this happens again. It has occured multiple times while driving, placing me in dangerous situation, because once in limp mode, I'm unable to accelerate to the side of the road. By vehicle has been at a Ford dealership for over 8 weeks now. The dealership is able to reproduce this issue. They have done some exploratory repairs by replacing the pedal assembly and throttle body but the problem remains. They're unable to diagnose what is causing the issue. Instead they are denying warranty claims and are replacing the ECM and engine wiring harness at my expense. While this most certainly repair this unknown electrical problem and will get my vehicle safely working, this critical issue will remain under diagnosed.
