Toyota is recalling 52,000 Avalon sedans because of a wiring problem that could cause a fire. The recall affects Avalons from the 2011 and 2012 model years. Toyota says cargo in the trunk could move the wires connected to the audio system subwoofer. If the wires contact the metal frame of the subwoofer, they could short circuit and cause the subwoofer to overheat. That increases the risk of a fire. Toyota says no injuries or fires have been linked to the problem, but it has received two reports of overheating.
