Tap a recall to see the problem, the risk and the fix.

Hybrid propulsion system: inverter; engine and engine coolingNov 14, 2012 · NHTSA campaign 12V536000 · 350,662 vehicles

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.

Steering:gear box:shaft sectorNov 14, 2012 · NHTSA campaign 12V537000 · 669,705 vehicles

Problem: Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 5, 2003, through March 30, 2009. 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.

Equipment:other:labelsFeb 3, 2010 · NHTSA campaign 10V036000 · 153,418 vehicles

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.

Steering:electric power assist systemMay 31, 2006 · NHTSA campaign 06V188000 · 170,856 vehicles

Problem: The intermediate shaft and sliding yoke in the electric power steering system can crack when large forces are applied and the connection may separate or the sleeve may fracture.

Air bagsApr 3, 2006 · NHTSA campaign 06V096000 · 133 vehicles

Problem: On certain vehicles, due to improper assembly of the air bag inflator, which is used in the side air bag, the curtain shield air bag, and the knee air bag assembly, some inflators were produced with an insufficient amount of the heating agents necessary for proper air bag deployment. In this condition, the expansion force of the gas may be insufficient to properly inflate the air bag when the srs system is activated during a crash.

Risk: This may increase the risk of injury to the occupant in the involved seating position in the event of a crash.

Fix: Dealers will replace the specific srs air bag. The recall began on april 6, 2006. Owners may contact toyota at 1-888-270-9371, scion at 1-866-548-1851, or lexus at 1-800-255-3987.
