Does the 2006 Toyota Prius have recalls?

6 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.

12V536000Fuel SystemNovember 14, 2012 · 350,662 units

Defect

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.

Consequence

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.

Remedy

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.

12V537000SteeringNovember 14, 2012 · 669,705 units

Defect

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.

Consequence

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

Remedy

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.

09V388000Speed ControlOctober 5, 2009 · 4,445,056 units

Defect

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.

Consequence

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.

Remedy

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.

Defect

06V096000AirbagsApril 3, 2006 · 133 units

Defect

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.

Consequence

THIS MAY INCREASE THE RISK OF INJURY TO THE OCCUPANT IN THE INVOLVED SEATING POSITION IN THE EVENT OF A CRASH.

Remedy

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.
