The subject vehicles are equipped with a factory‐installed subwoofer, located inside the trunk. Luggage in the trunk could come in contact with the subwoofer wire and move it out of its fixed position. If the wire touches the metal frame of the subwoofer, an intermittent short may occur causing the integrated circuit (IC) in the subwoofer amplifier to be damaged.


Safety Hazard

If this condition were to occur, the damaged IC may create a continuous electrical current into the subwoofer. As a result, the subwoofer could overheat, increasing the risk of a fire.


Description of the Remedy

The remedy for this condition will involve the installation of a spacer clip kit onto the subwoofer. Repair and Parts
