Seats; air bags:frontal:sensor/control module-inactiveJan 16, 2013 · NHTSA campaign 13V014000 · 3,235 vehicles

Problem: 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.

Fix: 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.

Problem: Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 6, 2003, through March 30, 2009 and FCHV-adv vehicles manufactured December 12, 2008, through September 13, 2011. During manufacturing, a scratch may have occurred inside of the electrically driven water pump at the coil wire. The coil wire may corrode at the scratched portion.

Risk: The corroded coil wire may break and the water pump could stop. The corroded coil wire could cause a short circuit between coil wires and a possible open fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash.

Fix: Toyota will notify its owners, and dealers will replace the electric water pump, free of charge. The recall began on January 17, 2013. Owners may contact their Toyota dealer or the Toyota Customer Experience Center at 1-800-331-4331.

The affected vehicles have a steering intermediate extension shaft assembly built with metal splines that complete the connection from the steering wheel to the steering gear. These splines may have been manufactured with an insufficient hardness.

Risk: Over time, the splines may wear and eventually fail resulting in a loss of steering ability, increasing the risk of a vehicle crash.

Fix: Toyota will notify owners, and dealers will inspect the extension shaft and replace it if it is one with insufficient hardness, free of charge. The recall began during December 2012. Owners may contact their Toyota dealer or the Toyota Customer Experience Center at 1-800-331-4331.

Vehicle speed control:accelerator pedalOct 5, 2009 · NHTSA campaign 09V388000 · 4,445,056 vehicles

Problem: Toyota is recalling certain model year 2004-2010 passenger vehicles. The accelerator pedal can get stuck in the wide open position due to its being trapped by an unsecured or incompatible driver's floor mat.

Risk: A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death.

Fix: Toyota filed an amended defect report on november 25, 2009, stating that dealers will modify the accelerator pedal and, on certain vehicles, alter the shape of the floor surface under the pedal. These changes address the risk of pedal entrapment due to interference with the floor mat. Redesigned accelerator pedals will become available beginning in april 2010 and dealers will replace any modified pedal with the new pedal if desired. Also, dealers will replace any genuine toyota or lexus all-weather floor mats with redesigned all-weather mats, or repurchase the previous mats from owners who do not want the new ones. Additionally, software modifications will be installed on camry, avalon and lexus es 350, is 350 and is 250 models that will ensure that the brake overrides the accelerator in the event both brake and accelerator pedals are applied. Toyota will begin mailing letters to owners on december 31, 2009. Owners may contact toyota at 1-800-331-4331, lexus at 1-800-255-3987.
