Recalls, owner-reported complaints, investigations and safety data

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.
0
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.

Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

The defect: REV Recreation Group (REV) is recalling certain 2017-2018 Fleetwood Discovery and Discovery LXE, and Holiday Rambler Endeavor, Endeavor XE, and Admiral XE motorhomes, as well as 2018 Monaco Diplomat, Fleetwood Pace Arrow, Bounder, Flair, and Storm motorhomes, and Holiday Rambler Navigator and Vacationer XE motorhomes. The affected vehicles may have been manufactured with headlights that do not have tempered glass lenses.
The risk: If the headlamp lens is not tempered, it may crack or break, which may cause decreased illumination and/or premature failure of the headlight bulb, increasing the risk of a crash.
The remedy: REV Recreation Group will notify owners, and authorized REV dealers will inspect, and if necessary, replace non-tempered, defective headlamp lenses with new headlamp lenses, free of charge. The recall began on September 8, 2017. Owners may contact REV customer service at 1-800-509-3417. REVs number for the recall is 170720REV.
