Service bulletin PIC6439

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.

Information for Dead Battery Condition Some customers may comment on the following conditions: • Dead battery • Dead battery after car sits a couple days Cause This condition may be caused by the OnStar® module staying awake, drawing power from the battery. Correction Note: If the vehicle is towed to the dealer with a dead battery, it is highly unlikely that a battery draw will be verified once the battery is charged. Verify that the vehicle VIN is flagged in the Global Warranty Management / Investigate History (GWM/IVH).
