Recall 13V396000133,081 vehicles

Problem: Toyota is recalling certain model year 2006-2010 Highlander hybrid vehicles manufactured February 16, 2005, through July 29, 2010; and model year 2006-2008 Lexus RX400h vehicles manufactured February 23, 2005, through December 2, 2008. The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.
Risk: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.
Fix: Toyota will notify owners, and dealers will replace the IPM free of charge. Owners may contact Toyota at 1-800-331-4331. Vehicles that had their IPM replaced under recall 11V-342 are not affected by this campaign.

Recall 11V539000420,326 vehicles

Problem: TOYOTA IS RECALLING CERTAIN MODEL YEAR 2004 AVALON VEHICLES; 2004 AND 2005 CAMRY, CAMRY SOLARA, HIGHLANDER, AND SIENNA VEHICLES, 2006 HIGHLANDER HYBRID; 2004 AND 2005 LEXUS ES330 AND RX330; AND 2006 LEXUS RX400H VEHICLES MANUFACTURED FROM JUNE 1, 2004 THROUGH MARCH 31, 2005, EQUIPPED WITH THE 1MZ-FE OR 3MZ-FE ENGINE. THE AMOUNT OF ADHESIVE AGENT APPLIED BETWEEN THE OUTER RING AND THE TORSIONAL RUBBER DAMPER (INNER RING) IN THE CRANKSHAFT PULLEY MAY BE INADEQUATE. IF THE ADHESIVE IS INSUFFICIENT, THERE IS A POSSIBILITY THAT THE OUTER RING MAY BECOME MISALIGNED AND IT MAY NOT PROPERLY ROTATE WITH THE INNER RING, CAUSING NOISE AND/OR ILLUMINATION OF THE BATTERY DISCHARGE INDICATOR LIGHT.
Risk: IN SOME CASES, THE BELT FOR THE POWER STEERING PUMP MAY BECOME DETACHED FROM THE PULLEY WHICH COULD RESULT IN A LOSS OF POWER STEERING AND A SUDDEN INCREASE IN STEERING EFFORT, INCREASING THE RISK OF A CRASH.
Fix: TOYOTA WILL NOTIFY OWNERS, AND DEALERS WILL CHECK THE CRANKSHAFT PULLEY TO IDENTIFY WHETHER IT WAS PRODUCED BY THE U.S. SUPPLIER. IF SO, THE DEALER WILL REPLACE THE PULLEY WITH A NEW ONE AT NO CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING EARLY JANUARY 2012. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.

Problem: TOYOTA IS RECALLING CERTAIN MODEL YEAR 2006-2007 HIGHLANDER HYBRID AND LEXUS RX400H PASSENGER CARS MANUFACTURED FROM FEBRUARY 16, 2005, THROUGH AUGUST 30, 2006. A MODULE INSIDE THE INVERTER MODULE MAY CONTAIN INADEQUATELY SOLDERED TRANSISTORS THAT DURING HIGH-LOAD DRIVING, MAY BE DAMAGED BY HEAT CAUSED BY THE LARGE CURRENT. IF THIS OCCURS, VARIOUS WARNING LAMPS, INCLUDING THE MALFUNCTION INDICATOR LAMP, SLIP INDICATOR LIGHT, BRAKE SYSTEM WARNING LIGHT, AND MASTER WARNING LIGHT, WILL BE ILLUMINATED ON THE INSTRUMENT PANEL.
Risk: THE VEHICLE MAY ENTER A FAIL-SAFE/LIMP-HOME MODE THAT LIMITS THE DRIVABILITY OF THE VEHICLE. IT IS POSSIBLE THAT THE HYBRID SYSTEM WILL SHUT DOWN WHILE THE VEHICLE IS BEING DRIVEN, CAUSING THE VEHICLE TO STALL UNEXPECTEDLY, INCREASING THE RISK OF A CRASH.
Fix: TOYOTA/LEXUS MAILED AN INTERIM OWNER NOTIFICATION ON JULY 19, 2011 TO ADVISE OWNERS OF THIS RECALL AND THE FACT THAT THEY WILL RECEIVE A FUTURE NOTICE WHEN PARTS BECOME AVAILABLE TO COMPLETE REPAIRS. TOYOTA DEALERS WILL INSPECT THE HYBRID INVERTER PRODUCTION NUMBER TO DETERMINE WHETHER THE INVERTER CONTAINS SUSPECT TRANSISTORS AND REPLACE THE MODULE FREE OF CHARGE. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.

Recall 11V112000769,379 vehiclesopened after NHTSA action (ODI)

Problem: TOYOTA IS RECALLING CERTAIN MODEL YEAR 2004-2006 HIGHLANDER, HIGHLANDER HYBRID, AND MODEL YEAR 2004-2007 LEXUS RX330, RX350, AND RX400H VEHICLES. IF THE FORWARD RETENTION CLIP USED TO SECURE THE FLOOR CARPET COVER, WHICH IS LOCATED IN FRONT OF THE CENTER CONSOLE, IS NOT INSTALLED PROPERLY THE COVER MAY LEAN TOWARD THE ACCELERATOR PEDAL AND INTERFERE WITH THE ACCELERATOR PEDAL ARM.
Risk: IF THIS OCCURS, THE ACCELERATOR PEDAL MAY TEMPORARILY BECOME STUCK IN A PARTIALLY DEPRESSED POSITION RATHER THAN RETURN TO THE IDLE POSITION. A STUCK ACCELERATOR PEDAL MAY RESULT IN UNINTENDED AND SUSTAINED VEHICLE SPEEDS AND MAKE IT DIFFICULT TO STOP, INCREASING THE RISK OF A VEHICLE CRASH.
Fix: DEALERS WILL REPLACE THE FLOOR CARPET COVER WITH A NEWLY DESIGNED ONE FREE OR CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING MARCH 2011. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.

Electrical system
MY VEHICLE IS DISPLAYING A HYBRID SYSTEM CHECK MESSAGE, AND THE HYBRID SYSTEM MALFUNCTIONS. THIS IS CAUSING THE VEHICLE TO STALL IN DRIVE WHILE THE VEHICLE IS IN MOTION. THE VEHICLE LOSES ALL CAPABILITIES TO PROPERLY FUNCTION. I WAS ON A CITY STREET WHEN THIS HAPPENED, AND HAD TO COAST THE VEHICLE DOWNHILL IN TRAFFIC TO PULL OVER. MY ENGINE CHECK LIGHT ALSO ILLUMINATED. THIS VEHICLE HAS NOT BEEN DRIVEN REGULARLY, AS I JUST PURCHASED IT FROM A DEALERSHIP THAT HAD BEEN SITTING ON IT FOR SOME TIME. THE CARFAX CHECK OUT FOR THE VEHICLE, SO IT COULD BE A FAULTY ELECTRICAL SYSTEM INVERTER.
