On certain vehicles, heat generated by the brake light bulbs could deform the base of the light socket. This deformation can cause movement in the socket-to-bulb connection, which may lead to a loosening of the electrical contacts in the socket and failure of the bulb to illuminate. Correction: Dealers will replace the rear lamp assemblies.
