Service bulletin Customer Letter

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.

A surge, vibration, or judder may be felt while driving under light acceleration. To minimize the possibility for the judder to occur, a software update for the transmission is available.
