2013 Prevost H3 problems, complaints & recalls
Safety recalls (2)
Electrical System:12v/24v/48v Battery 2014-02-06 · campaign 14V041000 · 450 vehicles
Defect: Marathon Coach, Inc. (Marathon) is recalling certain model year 2001-2013 Marathon Conversions Prevost XL, and H3 motorcoaches equipped with Sure Power-brand battery equalizers or DC-DC converters containing a particular epoxy sealing, aka 'potting', compound. The specific potting compound used in the subject products for insulation was found to be capable of conducting electricity after being exposed to heat.
Risk: Once electrically conductive, the material is capable of melting and burning, increasing the risk of a fire.
Fix: Marathon will notify owners, and Marathon service centers will replace the equalizers or converters, free of charge. The recall is expected to begin in March 2014. Owners may contact Marathon at 1-352-588-4500.
Equipment 2013-01-17 · campaign 13V015000 · 261 vehicles
Defect: Prevost is recalling certain model year 2010-2013 H3 and X3 coaches and MTH XLII-45E coach shells manufactured between June 29, 2009, up to June 4, 2012, and equipped with an Automatic Fire Detection and Suppression System (AFSS). There is the possibility that the AFSS could unintentionally activate due to wear of the linear thermal detection cable.
Risk: An activation of the AFSS causes the vehicle to come to an unplanned stop. This could increase the risk of a vehicle crash or personal injury.
Fix: Prevost will notify owners, and dealers will inspect and repair the linear thermal detector by adding a protective sheath, free of charge. The recall began in March 2013. Owners may contact Prevost at 1-418-883-2888 x 6558.
