Chevrolet Malibu electric issue related to battery control module, suspected factory defect on Chevrolet Malibu

Some Chevrolet Malibu owners report experiencing electrical issues related to the battery control module, which may be linked to a factory defect. Common symptoms include warning lights on the dashboard indicating battery system problems, diminished power that makes starting the vehicle difficult, and electrical malfunctions affecting features like audio and navigation systems. Additionally, a Technical Service Bulletin highlighted an electrical disconnect issue between the shifter and the Body Control Module, prompting dealerships to install an In-line Shifter Wire Harness Jumper to resolve the problem. While there was a special warranty extension for certain electric power issues related to the battery control module, this coverage expired in 2022.
