2006 Lexus RX 400h Service and Repair Manual
Regular price
$34.99 USD
Unit price
Fitment for this service and repair manual begins with the vehicle itself: it is written for the 2006 Lexus RX 400h and its 3.3L V6 hybrid (3MZ-FE), so the specifications, clearances and torque sequences it gives are the ones Lexus published for this year and drivetrain rather than figures carried over from an adjacent RX.
Engines
- 3.3L V6 HYBRID Naturally Aspirated
Trims

- FWD
Known issues on the 2006 RX 400h. Five recalls are on federal record for this model year. One is filed under engine and engine cooling: 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. Two sit under vehicle speed control and the accelerator pedal. In the first, the accelerator pedal may temporarily become stuck in a partially depressed position rather than return to the idle position, which may result in unintended and sustained vehicle speeds and make the vehicle difficult to stop; in the second, the condition may interfere with the accelerator pedal returning to the idle position, again increasing the risk of a crash. The remaining two cover the hybrid driveline, one filed under the electrical system and one under the hybrid propulsion system inverter, and both describe the same outcome: the vehicle may enter a fail-safe/limp-home mode that limits drivability, and the hybrid system may shut down while the vehicle is being driven, causing it to stall unexpectedly. Owners have filed 185 complaints for the year, and no technical service bulletins are on record for it. The diagnostic and repair procedures behind each of those systems are here.
From an unexpected stall traced back to the inverter to a pedal that will not return cleanly or a scheduled service on the hybrid system, it keeps you on the OEM procedure and the correct specification for your 2006 RX 400h.
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.
Consequence
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.
Remedy
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.
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.
Consequence
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.
Remedy
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.
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.
Consequence
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.
Remedy
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.
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.
Consequence
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.
Remedy
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.
ON CERTAIN SPORT UTILITY AND HYBRID VEHICLES, THE TWO RETAINING CLIPS FOR THE DRIVER'S SIDE FORWARD CENTER CONSOLE CAN BECOME LOOSE. IF BOTH CLIPS SEPARATE FROM THE FLOOR CARPET COVER, THE COVER MAY LEAN TOWARD THE ACCELERATOR PEDAL, CAUSING INTERFERENCE WITH THE ACCELERATOR PEDAL ROD.
Consequence
THIS CONDITION MAY INTERFERE WITH THE ACCELERATOR PEDAL RETURNING TO THE IDLE POSITION INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL REPLACE THE TWO FLOOR CARPET COVER RETAINING CLIPS FREE OF CHARGE. THE RECALL BEGAN ON JULY 24, 2006, AND SHOULD BE COMPLETED BY EARLY SEPTEMBER 2006. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331 OR LEXUS AT 1-800-255-3987.

AS I WAS PULLING INTO A PARKING SPACE ON THE 4TH LEVEL OF A 6 STORY PARKING BUILDING, I HAD MY FOOT ON THE BRAKE PEDAL AND THE VEHICLE WAS COMING TO A STOP, SUDDENLY THE VEHICLE ACCELERATED (LOUNGED) FORWARD. THERE WERE STEEL CABLES (RAIL GUARDS) THAT STOPPED THE VEHICLE FROM GOING OVER AND NOSE DIVING ONTO THE STREET BELOW. THE FRONT BUMPER AND THE HOOD WERE DAMAGED. I TOOK THE VEHICLE TO THE LOCAL LEXUS DEALER AND HAD THEM CHECK THE BRAKING SYSTEM FOR ANY DEFECTS. AFTER DOING A "HEALTH CHECK"
ALL SERVICE LIGHTS ARE ON, ABS VSC, AND INFO DISPLAY STATES SOME SORT OF VSC MALFUNCTION.
I WAS APPROACHING A LIGHT INTERSECTION AT 50MPH. WHEN LIGHT CHANGED TO RED I TRIED TO APPLY BRAKES ABOUT 1,000FT FROM INTERSECTION. CAR DID NOT SLOW DOWN AND BRAKES APPEARED NOT TO BE WORKING. I VEERED INTO MEDIAN TO AVOID STOPPED TRAFFIC IN FRONT OF ME AND THEN ENTERED INTERSECTION CLIPPING THE BACK OF ANOTHER VEHICLE. LEXUS DEALER REPORTED NO DEFECT WITH BRAKES. THIS VEHICLE HAD BEEN STORED IN A FLORIDA GARAGE AND IT WAS THE 1ST TIME IT HAD BEEN DRIVEN IN SEVERAL MONTHS. THIS HAS NOT HAPPENED
FOLLOWING ARE THE SERIES OF EVENTS ON NOVEMBER 11, 2009: 1.I WAS LOOKING FOR A PARKING SPACE IN THE PARKING GARAGE OF UNIVERSITY OF MARYLAND. 2.I FOUND ONE OPEN SPACE ON MY LEFT. 3.I APPLIED THE BRAKES AND SLOWED DOWN MY CAR TO ALMOST ZERO SPEED. 4.I TURNED THE STEERING WHEEL TO LEFT TOWARDS THE PARKING SPACE. 5.I SLOWLY RELEASED THE BRAKES TO LET THE CAR SLOWLY ROLL INTO THE PARKING SPACE. 6.SUDDENLY MY CAR EXPERIENCED SUDDEN ACCELERATION. 7.I DID NOT UNDERSTAND WHAT HAPPENED. I TRIED MY
I OWN A 2006 LEXUS RX400H WHICH I BELIEVE HAS EXACTLY THE SAME FLAW AS RECENTLY REPORTED IN THE PRIUS. SEVERAL YEARS AGO I HAD A MINOR ACCIDENT CAUSED BY MY CAR LURCHING FORWARD DURING BREAKING WHICH CAUSED ME TO HIT THE CAR IN FRONT OF ME. WHEN I BROUGHT MY CAR INTO THE LEXUS OF WATERTOWN DEALERSHIP WHERE I PURCHASED THE VEHICLE I REPORTED THAT I THOUGHT THE ISSUE MIGHT BE RELATED TO THE TRANSITION BETWEEN THE REGENERATIVE BRAKING SYSTEM AND THE REGULAR BRAKE. IT SEEMED LIKE THE REGENERATIVE
AS I WAS APPROACHING A RED LIGHT I STARTED TO BRAKE. MY BRAKES DID NOT ENGAGE EVEN WHEN I PUMPED. I SWUNG MY CARE TO THE LEFT SO I WOULD NOT REAR END THE CAR IN FRONT. I HIT THE CAR ON THE PASSENGER REAR CORNER (ON MY LEFT) AND TOTALED MY LEXUS. MY BRAKES WERE FINE UP TO THAT MOMENT AND ALTHOUGH I COULD NOT DRIVE THE CAR AWAY FROM THE SCENE THEY SEEMED TO BE WORKING AGAIN WHEN I PRESSED ON THEM (ALTHOUGH I CANNOT BE SURE AS THE CAR WAS STILL). IT WAS HORRIBLE. *TR
