14V273000 · TIRES:TEMPORARY/EMERGENCY SPARE TIRE

Filed 2014-05-22 · 419,520 vehicles

Defect: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2004-2011 Sienna vehicles originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin and the District of Columbia. The affected vehicles have a spare tire carrier assembly mounted under the vehicle whose attachment cable may corrode due to high concentrations of road salt splashing onto the spare tire carrier.

Risk: If the carrier cable is corroded due to road salt, the spare tire may separate from the vehicle, increasing the risk of a crash.

Remedy: Toyota sent owners in August 2014 an interim notification to advise owners of the recall and that dealers will perform an interim remedy to remove the spare tire and relocate it to the luggage compartment, free of charge. Owners are being mailed a second letter as parts become available and dealers will replace the spare tire carrier assembly with an improved one, free of charge. The remedy campaign is being performed in phases. The first phase of the recall began July 7, 2015. Owners may contact Toyota customer service at 1-800-331-4331. NOTE: 2004-2010 Siennas subject to this recall were subject to recall campaign 10V-160 initiated in 2010. Those owners are advised that they must have their vehicles remedied again under this campaign and that having the earlier recall completed did not remedy their vehicles. Additionally, model year 1998-2003 Siennas were recalled as part of safety recall 10V-160. Owners of those vehicles that have not had not the remedy performed on their vehicles, should contact their Toyota dealer to schedule a free repair.

13V429000 · POWER TRAIN:AUTOMATIC TRANSMISSION

Filed 2013-09-26 · 614,722 vehicles

Defect: Toyota is recalling certain model year 2004-2005 Sienna vehicles manufactured January 10, 2003, through August 10, 2005; and model year 2007-2009 Sienna vehicles manufactured February 20, 2007, through December 12, 2008. In the affected vehicles, due to a problem within the shift lock solenoid, there is a possibility that the shift lever could be moved out of Park position without depressing the brake pedal.

Risk: If the shift lever is moved out of the Park position without the brake applied, the transmission will either engage a drive gear or Neutral, increasing the risk of a backover or roll away crash.

Remedy: Toyota will mail interim notifications to owners beginning in late October 2013. When parts are available, owners will be sent a second notice and dealers will replace the shift lock solenoid, free of charge. Owners may contact Toyota at 1-800-331-4331.

Service bulletins

Toyota issued 247 service bulletins listed against this model year, most often about equipment.

A bulletin tells dealers how to fix a known condition. It is not a recall and not a defect finding. Most bulletins cover several model years at once, so one listed here may not be specific to this year. The number of bulletins tracks how long and how widely a model was sold, so it is not a measure of reliability.

How to read this page

Complaint counts are not failure rates. A model that sells more cars draws more complaints, and owners file more often after news coverage or a recall. That is why this page compares a model year only with other years of the same generation, never with other models.

Each complaint is counted once, even when it names several components; a complaint that names several systems appears under each of them. Owner reports are quoted as filed and have not been verified by NHTSA or by us.

Every model year of this Sienna, including the ones without a page of their own, is listed on the Toyota Sienna model page.
