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.

Consequence & remedy

Consequence: 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.

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.
