NHTSA Complaint #11587428 — 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."
