SUMMARY:
Thor Motor Coach (Thor) is recalling certain model year 2006-2013 Windsport, model year 2006-2010 Magellan, model year 2007-2013 Hurricane, model year 2009-2013 Serrano and model year 2011-2013 A.C.E motorhomes. The motorhomes are equipped with an RV Custom Products Battery Control Center (BCC) which may experience a failure while the motorhome is in motion.
CONSEQUENCE:
If the BCC fails, all power may be lost to the motorhome chassis, including all lighting, making the vehicle very difficult to operate, increasing the risk of a crash.
REMEDY:
Thor will notify owners, and dealers will rewire the BCC free of charge. A notification schedule has not yet been provided. Customers may contact Thor at 1-877-855-2867. Thor's recall campaign number is RC000077.
