- 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.
- Consequence
- This corrosion may create a short circuit between the power stud and the alternator body, which in turn could result in burning of the power stud or the power cable end. This could increase the risk of a fire. Additionally, the vehicle battery could discharge which could cause the vehicle to stall.
- Remedy
- Mci will inspect and modify the alternator installation free of charge. The safety recall began on November 30, 2011. Owners may contact mci customer service at 1-800-241-2947.

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.
Has your MCI been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A MCI dealer can also check your VIN. Recall repairs are free.
