2020 Ford F-53

While driving the cruise control shut off, all dash lights came on - ABS brakes, traction control, etc. We stopped at the next service center and called tech support. Tech support felt it was a bad sensor which would correct itself after engine shut off for a little while. The motorhome would be safe to get to a repair center. Shutting the engine off did not correct the issue - the lights continued to come on. The repair center "found the wiring harness was loose at L/F rear of engine and was resting on the exhaust manifold flange. Verified severe wiring damage from laying on the flange - lots of wires were burnt up." "The possiblity of causing a severe fire."

In ordinary driving conditions when a crosswind is present, the Electronic Stability Control warning light comes on, disabling the vehicle’s traction control, cruise control and hill start assist, and possibly affecting the vehicle’s Anti-Lock Braking system. The warning light goes off after the engine is stopped and restarted. This condition has surfaced multiple times since I took ownership of this vehicle in April 2021. The sudden and unexpected loss of traction control and cruise control in windy or stormy conditions when the road surface may be slick with snow or rain creates a hazard to driver and passenger safety.

The ABS and traction control warning light on the dash is in. When this happens the Hill assist is inoperable and the cruise control does not work I think it is a safety issue for these systems not to work. I have had my vehicle at the Ford dealership 2 times and the issue has not been repaired. The dealership said to drive it.

The following warning messages appeared at once and the cruise control was canceled causing Motorhome to slow suddenly on Turnpike. Hill assist inactive ABS inactive Traction control inactive This happened 3 times in a 2 hour drive on 11/15/2021. It has happened before but eventually goes away. It now happens more frequently.
