Service bulletin 11-176-17

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.

Depending on vehicle use conditions, the battery state of charge value may differ slightly from the actual value. The new logic will enhance charging system control and result in improved battery life.
