Service bulletin 167-B1515-12

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

SB-15-016 New parts are available to prevent repeat exhaust manifold stud failures on the J05 engine. This bulletin provides instructions for installing longer manifold studs at the #4 cylinder location.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
