NHTSA lists 1 safety recall and 106 owner complaints for the 2011 Toyota Avalon. Most complaints involve steering (31) and electrical system (25). The EPA rates it 23 mpg combined.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2011-2012 Toyota Avalon vehicles manufactured February 9, 2010, to October 22, 2012. In the affected vehicles, the sub-woofer speaker located in the trunk may experience an intermittent electrical short which may cause damage to the integrated circuit (IC) in the audio amplifier. In some cases, the damaged IC may allow a constant electrical current flow to the sub-woofer.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
