Chevrolet Malibu electrical issues with anti-theft system and intermittent door radio speakers on Chevrolet Malibu

Some Chevrolet Malibu owners report experiencing electrical issues related to the anti-theft system, such as receiving the Service Theft Deterrent System alert message, which often indicates a malfunction due to a dead battery or key problems. Additionally, some owners have noted intermittent starting issues, warnings, and AC malfunctions, suggesting there may be underlying electrical problems beyond just the battery. The anti-theft system itself can disable the engine or ignition if it detects unauthorized attempts to start the vehicle, leading to further complications. When dealing with these issues, owners are advised to wait for the system to reset, use a spare key in good condition, and check for wear on the primary key to enhance recognition. Furthermore, some Chevrolet Malibu owners have reported intermittent problems with door radio speakers, prompting recommendations to inspect electrical connections, wiring, and speaker components for loose connections or faults.
