Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

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. 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).
The risk: Damage to the fuel pump circuit in the wiring harness could result in an unexpected engine stall. Damage to the ABS wiring can lead to reduction of ABS functionality and a loss of roll stability control (RSC) functionality. These scenarios increase the risk of a crash.
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. If damage is found, dealers will splice in new wire and apply anti-abrasion tape over the area and ensure clearance to surrounding components. All services will be performed free of charge.
