Component= Traction control and cruise control. Safety risk=Driving a Ford e-450 Class C RV on interstate at 63 MPH going generally up hill with cruise control on, the "Service AdvanceTrac" warning light came on dashboard. I Immediately lost cruise control capability and steering became a little shakey. Pulled into rest area shut vehicle off. A few minutes and started again. Error went away and cruise control was functioning. Happened again a few hours later and I did the same thing and continued on. What happened=As I was driving, the " Service Advance Traction" light came on and the cruise control stopped, my class c rv immediately slowed at a high rate, a semi was behind me trying to get over to the middle lane. When I slowed down suddenly due to the cruise control going out, the semi had no choice but to change lanes quickly missing the back of my vehicle by a foot or so. If he was not alert as to what was happening, I most assuredly would not be typing this letter. It was that close!! Note= This also happened last year as we only take the RV out a few weeks out of the year. I brought it to Klammer Ford in New Port Richey F1l immediately after we got back from the last trip. They could not reproduce issue or find anything wrong Lamps= The only warning light that came on was a "Service Advance traction" light. No prior indication of any kind.

What owners say
The contact owns a 2021 Ford E-450. The contact stated while driving the RV 60 MPH with the cruise control feature turned off, the stabili-trac warning light illuminated and the RV decelerated. The contact was able to control the RV, and once the contact turned off and restarted the RV, the RV operated normally. The RV was not diagnosed. The dealer was contacted and stated that the failure was not a known failure. The dealer also confirmed that the RV was not under recall. The manufacturer was not contacted. The failure mileage was 18,000.
Driving in about 30mph gusting cross winds which required constant small steering corrections. Sudden loss of braking ABS, loss of Cruise Control, loss of Pre-Collision Assist, loss of Hill Start Assist, and related functions. Warning message: Service AdvanceTrac. Three incidents First and second incidents: After sitting with ignition key off for about 15 minutes, vehicle operated as normal. Third incident: Would not normalize after setting with ignition key off. Faults continued.
ADAS keeps faulting and disabling the cruise control, pre-collision braking, hill hold assist, and skid control functions. The event occurs at highway speeds with strong crosswinds that rock the vehicle in a busy side-to-side motion as gusts hit the vehicle. The system seems to reset after turning the engine off & restarting. But the loss of some of the safety features is worrisome in traffic.
The Service Advance Trac light comes on sporadically. This also triggers the Cruise Control and Hill Start Assist to turn off. Any of these malfunctions could prove to be a safety issue particularly with regard to stability and control of the vehicle. The vehicle has not yet been to a dealer for these issues as we are traveling. The malfunction has occurred about 5-6 times while driving, without any particular triggers.There were no early warnings and the first time the service light came on was June 18th and we were on a two lane flat road doing about 50 mph. The Advance Trac (and cruise/Hill Start) remains non-functional until vehicle is turned off for at least 10 minutes. It then often resets and performs normally until the next failure - which does not seem to be predictable.

- What is wrong
- Ford Motor Company (Ford) is recalling certain 2021 E-350 and E-450 vehicles. A wire harness in the rear of the vehicle may contact the vehicle frame, resulting in damage to the circuits that support the fuel pump and the anti-lock braking system (ABS).

- Ford will notify owners, and dealers will inspect the wire harness for damage. If no damage is found, dealers will apply anti-abrasion tape over the area and ensure clearance to surrounding components.
