Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
