Summary:
MOTOR COACH INDUSTRIES (MCI) IS RECALLING CERTAIN MODEL YEAR 2010-2011 D4505 MOTOR COACHES MANUFACTURED FROM MAY 1, 2010, THROUGH SEPTEMBER 30, 2011. THESE VEHICLES WERE EQUIPPED WITH PENNTEX ALTERNATORS THAT, AS INSTALLED, MAY COLLECT MOISTURE AT THE POWER STUD. THIS MOISTURE MAY RESULT IN CORROSION BUILDUP AT AND AROUND THE POWER STUD BASE.
