Typical body and structure symptoms owners report

  • Power sliding doors fail to open or close properly, sometimes trapping items in the door mechanism near the tractor cable.
  • Owners report the recall remedy for the sliding door junction block and wire harness (campaign 16V858000) was delayed because replacement parts were unavailable.
  • Rear liftgate misalignment causes clunking noises when closing and water leaking through the top of the gate.
  • The hinge on the back sliding door was reported to be rusting, with Toyota describing it as cosmetic despite proximity to door wiring.
  • In a rear-end collision, the vehicle caught fire and burned to the frame, and the owner could not open the door to exit quickly.
  • Airbags reportedly failed to deploy in a side-impact crash despite the other vehicle's airbags deploying.

  1. NHTSA 16V858000Nov 29, 2016Structure & Body744,437 vehicles

    Structure:body:door

    Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2011-2016 Toyota Sienna minivans manufactured January 4, 2010, to August 12, 2016. If the power sliding door is unable to be opened when commanded, such as if the door is frozen shut, the door may subsequently open unexpectedly, possibly while the vehicle is moving.

    Risk: If door opens while the vehicle is moving, there would be an increased risk of injury to the vehicle occupants.

    Remedy: Toyota will notify owners, and dealers will replace the junction block, rear sliding door wire harnesses, and install two sub wire harnesses, free of charge. The recall began on July 28, 2017. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is G04.

    Seats

    Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.

    Risk: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

    Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.
