SUMMARY:
Nova Bus is recalling certain 2009-2012 model year LFS and LFS HEV transit buses equipped with Sure Power DC-DC converters containing a particular epoxy sealing, aka 'potting', compound.

Once electrically conductive, the material is capable of melting and burning, increasing the risk of a fire.

REMEDY:
Nova Bus will notify owners and dealers will inspect and replace the converters, as necessary, free of charge. The recall is expected to begin in January 2014. Owners may contact Nova Bus at 1-450-472-6410. Nova Bus's numbers for this recall are CR3030, CR3031, CR3032, CR3033 and CR3034 (depending on the converter's part number and location of in the vehicle).
