- 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.
