The defect
Thor Motor Coach (TMC) is recalling certain 2020-2021 Quantum, Chateau and Four Winds, and 2020 Vegas and Axis motorhomes built on a Ford E-series chassis.

The remedy
TMC will notify owners, and Ford 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.
