Service bulletin 14648

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

14648 - Customer Satisfaction Program. Certain 2008-2010 model year General Motors vehicles have a performance issue with their OnStar modules that could impact the vehicle?s battery life. If the vehicle?s OnStar module contains this condition, the OnStar green telltale light will be illuminated even when the vehicle is off. This condition can drain the vehicle?s battery if the vehicle is not started for approximately four days. The condition may also render the OnStar system inoperative, which would disable all OnStar services, including automatic crash response and emergency roadside services. This condition can occur even if the vehicle is not actively subscribed to OnStar. Dealers are to remove the fuse for the OnStar module to reset it.
