Defect

Allied Recreation Group, Inc. (ARG) is recalling certain model year 2010-2011 Holiday Rambler Admiral, 2009-2014 Holiday Rambler Ambassador, 2010 Holiday Rambler Arista, 2010-2014 Holiday Rambler Endeavor, 2009-2011 Holiday Rambler Neptune, 2011-2014 Holiday Rambler Vacationer, 2009-2011 Monaco Cayman, 2010-2014 Monaco Diplomat, 2014 Monaco Dynasty, 2009-2014 Monaco Knight, 2012-2013 Monaco LaPalma, 2009-2013 Monaco Monarch, 2009-2011 Monaco Riptide, 2008 Safari Passage, and 2008 Safari Simba motorhomes. The affected vehicles are equipped with certain Lippert-brand Coachstep Double Electric Steps. These steps use a bolt to attach the fan gear assembly to the steps. This bolt may fracture allowing the fan gear to disengage from the steps. As a result, the steps may not remain in the expected position and may be unstable.

Consequence

Unstable entry and exit steps increase the risk of injury.

Remedy

ARG will notify owners and dealers will install a retainer bracket to reinforce the operating mechanism, free of charge. The recall began on February 12, 2016. Owners may contact ARG customer service number at 1-800-509-3417. ARG's number for this recall is 151216REV.

Consumer complaints filed with NHTSA

Representative excerpts, cleaned of personal information. These are consumer statements, not verified defects.

“WHEN STOPPED AND EXITING COACH, ENTRY STEPS COLLAPSED TOSSING ME AROUND. THE STEPS WOULD NOT RETRACT AFTERWARDS AND SO I HAD TO PUSH THE STEPS UP AND TIE THEM UP SO WE COULD COMPLETE THE TRIP USING A SHORT LADDER TO GET IN AND OUT OF THE COACH. FURTHER RESEARCH SHOWS THE BOLT HOLDING THE FAN GEAR…”
