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.

Flash: Diagnostic and System Improvements This bulletin involves selectively erasing and reprogramming the Powertrain Control Module \(PCM\) with new software.
