Service bulletin Dealer 37M9

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

An irregularity in the transmission case casting may cause incorrect seating of the exhaust bracket connection. This can result in an uneven contact surface, and as a result the bolts for the exhaust system bracket can become loose.
