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 \(GWM/IVH\). If the VIN is flagged, do a Blue Button Press from the vehicle and request a "Re\-configuration" and operational evaluation. - [20NA080](/bulletins/10174297.md), 2020-04-27, Service bulletin: ELECTRICAL SYSTEM:12V/24V/48V BATTERY; SEATS; EQUIPMENT ADAPTIVE/MOBILITY.
