Diagnose a parasitic battery drain, including glove box, trunk, and dome lights that may stay on. If money is tight, disconnect the battery after driving and reconnect it before starting, since repeated drain can damage the battery. Treat the brief radio shutoff as secondary until the drain is found.
The owner of a 2002 Grand Am with 57,000 miles must jump-start the car every time despite installing a new battery in August. While driving, the radio briefly shut off and then came back on. The expert says a parasitic draw is the likely cause and should be diagnosed by someone with electrical experience. As a temporary money-saving step, the battery can be disconnected after driving, and the owner can check whether the glove box, trunk, or dome lights stay on. The radio issue is not the priority.
