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.

ElectricalFuel system
Filed Apr 25, 2023

Fuel line to generator is long rubber hose rubbing on screws. Same with electrical wires. Exhaust from generator and vehicle coming back in from exposed holes in floor under cabinetry. I have informed THOR motor coach. This vehicle is unsafe and could catch fire due to rubber fuel line leaking onto exposed electrical connections or exhaust. Holes in floor for tubes and electrical are not sealed allowing fumes to come in. Couch that has seatbelts attached, metal is cut into two parts allowing seat belts to pull on separate metal bars that would break loose. Metal bar should be solid across, cut out is hidden by couch. Wires behind cabinetry floats around, nothing to hold them from flopping around eventually causing shorts. With as many unsafe issues, it would appear no one has inspected these changes THOR has made to the Dodge Promaster.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
