Service bulletin PI 0848

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

ON CERTAIN MACK CXU MODELS EQUIPPED WITH COMPRESSED NATURAL GAS (CNG) ENGINES, BUILT BETWEEN 07/01/2013 AND 12/30/2013, THERE MAY BE MISSING WIRE SEALS IN THE HARNESS THAT CONNECT THE CHASSIS TO THE TANK. THIS COULD CAUSE CORROSION IN CONNECTIONS AS WELL AS ALLOW THE WATER TO WICK UP TO THE CHASSIS CONNECTOR. THIS IS DUE TO A SUPPLIER ISSUE DURING THE ASSEMBLY OF THE HARNESS.
