The 12-volt cable, located behind the right-front headlight, could rub against the carbon-fiber paneling causing the cable to short, begin smoking and possibly catch fire, Tesla said.

The cable is part of a backup system that powers the headlights, taillights, turn signals and airbags if the primary 12-volt cable fails.

Tesla will notify 439 Roadster owners of the recall and send a service team to their homes to check the placement of the cable and install a protective sleeve.
