Service bulletin SI 3110

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This Service Bulletin informs affected customers that they may experience water intrusion into the interior cavity of the front junction box compartment on model year 2012-2017 MCI J4500 model coaches, and that an additional seal on the interior face of the door and a door stop will reduce the potential for water intrusion.
