According to Toyota, it's possible for the subwoofer's wires to move out of position if contacted by cargo in the trunk. If one of the wires then contacts the metal frame of the speaker, it could trigger a short circuit. "If this occurs, the subwoofer could overheat, increasing the risk of a fire," according to the automaker.
"There were two reports of thermal events – no outright fires," said Toyota spokesperson Cindy Knight to Autoblog. Toyota reports there are no reports of injuries, fatalities or crashes from this problem.
Dealers will repair this problem at no cost, but until then, they will immediately disconnect the rear subwoofer as a precaution for owners. The recall notices will be sent out in mid-February, according to Knight.
TORRANCE, Calif., January 28, 2015 – Toyota Motor Sales, U.S.A., Inc., today announced plans to conduct a safety recall of approximately 52,000 Model Year 2011-2012 Avalon sedans.
In the involved vehicles, cargo could contact one of the audio system subwoofer wires located inside the trunk, and move the wire out of its normal position. If one of these wires contacts the metal frame of the subwoofer, it may result in an intermittent short circuit. If this occurs, the subwoofer could overheat, increasing the risk of a fire.
Toyota is not aware of any crashes, injuries, or fatalities caused by this condition.
Owners of the involved vehicles will receive a notification by first class mail. Toyota dealers will provide a repair for the audio system. Until the remedy is available, as a precaution, Toyota dealers will disconnect the rear subwoofer.
