Recalls
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.
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.
Whether a recall was fixed on a particular car is known only to the manufacturer: check the VIN at nhtsa.gov/recalls.
