Thor Motor Coach Four Winds Recall 20V303: Wiring May Cut Fuel Pump and Anti-Lock Brake Power

NHTSA campaign 20V303, reported May 27, 2020, 34 vehicles potentially affected.

What this recall means for you

A wire harness in the rear of these motorhomes can rub against the vehicle frame. Over time this can damage the circuits that support the fuel pump and the anti-lock braking system (ABS).

Damage to the fuel pump circuit could cause the engine to stall unexpectedly. Damage to the ABS wiring can reduce ABS function and cause loss of roll stability control, which increases the risk of a crash.

The repair is free at an authorized Ford dealer. The dealer will inspect the harness and either add anti-abrasion tape and confirm clearance from nearby components, or splice in new wire and add the tape if damage is found. Owners can also contact Thor Motor Coach customer service at 1-877-855-2867 using recall number RC000189, and should check their VIN for open recalls.
