What can fail
Trunk cargo can shift the sub-woofer's soft wire out of position. If the wire contacts the sub-woofer's metal frame, it may short and damage the audio amplifier's chip. A damaged chip can cause continuous current flow to the sub-woofer, making it overheat and creating a fire risk.
What the fix does
Dealers will replace the audio amplifier and install a protective cover around the sub-woofer. Until then, dealers will disconnect the rear sub-woofer.
