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.

From owner reports, verbatim

I am the owner of a Thor Sequence 20K RV built on a 2022 Ram ProMaster 3500 chassis, purchased new in Florida. My vehicle Vin [XXX] is subject to safety recall # 25V-720 involving a potential engine fire- compartment fire risk. There is no repair or remedy currently available and no timeline has been provided by the manufacturer. Because of the fire risk, the vehicle is unsafe to operate. In addition the open safety recall has rendered the vehicle unsellable and untradeable, causing substantial loss of value and use through no fault of my own . Dealers and sale platforms refuse to accept the vehicle due to unresolved fire risk recall. The vehicle is a RV which increases the severity of safety risk due to fuel, electrical systems and living components. I am requesting NHTSA to review due to ongoing safety hazard and lack of manufacturer resolution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Too few reports in this category for a page of its own — they appear in the full complaint list.

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.
