DRIVER STARTED TO BACK UP A 2006 TOYOTA HIGHLANDER HYBRID IN A PARKING LOT. IT SHOT BACK AT MAXIMUM ACCELERATION JUMPING A CURB AND STRIKING A PEDESTRIAN. BY THEN, DRIVER HAD BRAKES ON AND SHIFTED INTO NEUTRAL. SHE PUT THE CAR INTO DRIVE AND IT AGAIN ACCELERATED TO THE MAXIMUM STRIKING HER HUSBAND. AT THE TIME, WE COULDN'T FIGURE OUT WHAT WAS WRONG. WE ASSUMED, SOMEHOW THE DRIVER, WHO HAD AN IMPECCABLE RECORD, HAD DONE SOMETHING WRONG. NOW, WITH ALL THE PUBLICITY, WE BELIEVE IT WAS CAUSED BY THE ELECTRONIC CONTROLS. NOTHING ELSE SEEMS AS LIKELY BECAUSE WE HAD NO REASON TO BELIEVE THERE WAS AN ELECTRONIC FAILURE, NOTHING WAS DONE. *TR

FAILURE OF 2006 HIGHLANDER HYBRID BRAKES TO MAINTAIN CONSISTENT RESISTANCE TO FORWARD MOTION. THIS FAILURE OCCURS REPEATEDLY AND CAUSES MUCH ANXIETY AND HEART PALPITATION UPON OCCURRENCE. THIS FAILURE WAS BROUGHT TO THE ATTENTION OF OUR LOCAL DEALER AND THEY CLAIMED TO NOT HAVE ANY INDICATIONS OF THE PROBLEM. I ALSO BROUGHT THEM COPIES OF NUMEROUS REPORTS WHICH READ THE SAME AND INDICATED EXTREMELY SIMILAR CONDITIONS. 11/22/2006 REPORTED TO LOCAL DEALER BRAKE CONCERNS. THEIR NOTES WERE:INTER. COND. MORE PRONOUNCED DURING 1ST FEW APPLICATIONS IN THE MORNING. C/S PEDAL SEEMS TO "FADE" & ENGINE HAS A SLIGHT SURGE WHEN BRAKING. CUSTOMER HAS LEFT VEHICLE FOR THE DAY & OVERNIGHT IF NECESSARY TO DUPLICATE CONCERN. RESULTS: ROAD TESTED 3 TIMES. CONCERN COULD NOT BE DUPLICATED. BRAKE CALIPERS & HARDWARE FUNCTIONING PROPERLY AT THIS TIME. NO REPAIRS MADE AT THIS TIME. WHAT I ACTUALLY TOLD THEM WAS THAT THE VEHICLE SURGED FORWARD WHEN THE BRAKES SEEMED TO FAIL . 10/02/07 BRAKE CONCERNS- PER PREVIOUS ADVISE, REPLACE FRONT PADS, RESURFACE ROTORS REMOVED AND REPLACED FRONT PADS AND RESURFACED ROTORS. CHARGE 235.04. TALKED TO SERVICE MANAGER ABOUT BRAKE CONCERNS. TALKED TO MY SALESMAN ABOUT BRAKE CONCERNS, TALKED TO DEALER MANAGER ABOUT BRAKE CONCERNS. REPORTED ON MOST SERVICE SURVEYS AND IN PERSON TO SURVEY CALLERS. IRONICALLY, DEALER SUGGESTS FRONT BRAKE PADS SHOULD BE REPLACED NOW AGAIN. TOYOTA HAS NEVER CONTACTED ME BACK AFTER ANY OF MY REPORTS TO THEM. ONLY THE LOCAL SERVICE MANAGER EVER CALLED ME BACK ABOUT THIS PROBLEM AND HE AFFORDED NO REMEDY. *TR

I OWN A 2006 TOYOTA HIGHLANDER HIGHBRID, WHICH I PURCHASED NEW. I HAVE NOT HAD A RUNAWAY SITUATION, BUT HAVE EXPERIENCED POWER SURGES WHILE BRAKING AND ONLY EXPERIENCED THESE DURING THE BRAKING PHASE. THE APPROXIMATE SPEEDS DURING THESE BRAKING EVENTS WERE BETWEEN 20-45 MPH. THE SURGING LASTS FOR APPROXIMATELY 2-3 SECONDS, WITH THE VEHICLE LUNGING FORWARD WHILE MY RIGHT FOOT BEING ON THE BRAKE. I DISCUSSED THE ISSUE WITH HECKER TOYOTA AND SERVICE ADVISOR . I THOUGHT THERE WAS A PROBLEM WITH THE CVT TRANSMISSION AND SERVICE ADVISOR TEST DROVE THE VEHICLE WITH NO PROBLEMS DETECTED. SERVICE ADVISOR ALSO STATED THERE WERE NO TOYOTA SERVICE BULLETINS FOR ANY ISSUES LIKE THIS. I HAVE ENCOUNTERED THIS SITUATION APPROXIMATELY 10-11 TIMES SINCE NEW. THE PROBLEM DOES NOT SEEM TO BE TEMPERATURE RELATED. I DON'T RECALL ANY SURGES WHEN COLD (BELOW 20F OR COLDER) BECAUSE MN ROADS USUALLY HAVE SOME ICY OR SLIPPERY CONDITIONS AND I WOULD REMEMBER THIS SITUATION. *TR

2006 TOYOTA HIGHLANDER HYBRID OCCASIONALLY GET A FEELING OF "NO BRAKES" WHEN APPLYING THE BRAKES. THEY HAVE ALWAYS STOPPED THE CAR, BUT SOMETIMES THERE IS A BRIEF FEELING THAT THEY ARE NOT WORKING I HAVE REPORTED IT TO THE DEALER ON AT LEAST 3 OCCASIONS THAT I RECALL. THE FIRST TIME THEY TURNED THE ROTORS, THE SECOND TIME THEY TOLD ME THERE WAS NOTHING WRONG. THE THIRD TIME THEY SAID IT WAS DURING THE TRANSITION FROM REGENERATIVE BRAKING TO HYDRAULIC BRAKING AND THAT "THEY'RE ALL LIKE THAT."

WE BOUGHT A NEW 2006 TOYOTA HIGHLANDER HYBRID IN 2005 AND, FROM TIME TO TIME SINCE WE BOUGHT IT, THE ACCELERATOR PEDAL KIND OF STICKS OR SURGES IN CERTAIN DRIVING CONDITIONS. WHEN YOU TRY TO REDUCE SPEED BY TAKING YOUR FOOT OFF THE GAS PEDAL. IT SOMETIMES DOES NOT IMMEDIATELY RESPOND, IT TAKES A FEW SECONDS TO REDUCE SPEED AND SOMETIMES ACTUALLY SURGES A LITTLE, WHICH IT ALSO DOES SOMETIMES WHEN YOU ARE DRIVING AT A CONSISTENT SPEED. I THOUGHT IT HAD TO DO WITH THE HYBRID FEATURE AND JUST SORT OF LEARNED TO BE SENSITIVE TO IT AND HIT THE BRAKES IF IT NEEDED IT, BUT THIS SOUNDS LIKE WHAT IS GOING ON WITH OTHER MODELS SUBJECT TO THE RECALL AND, AS OUR MODEL IS NOT SUBJECT TO THE RECALL, I AM CONCERNED ABOUT IT.

PE11005 · Hybrid Inverter Failure - Vehicle Stall

Opened Feb 15, 2011 · Closed Jul 20, 2011

Status: closed (inferred from source dates) · Hybrid Propulsion System: Inverter

In a June 29, 2011 letter to NHTSA, Toyota submitted a Defect Information Report regarding a safety recall of certain Toyota Highlander Hybrid and Lexus RX400h vehicles to address a defect condition with the hybrid inverter assembly (NHTSA Recall No. 11V-342).Toyota's letter identified a defect related to inadequately soldered transistors on the Intelligent Power Module (IPM) of some of the subject vehicles that could result in sudden loss of power while driving.Toyota's remedy procedure instructs dealers to inspect the hybrid inverter production number to determine if the inverter contains suspect transistors.If so, the dealer will replace the IPM.The recall covers approximately 45,528 model year (MY) 2006 and 2007 Toyota Highlander Hybrid vehicles manufactured from February 16, 2005 through August 29, 2006 and approximately 36,745 MY 2006 and 2007 Lexus RX400h vehicles manufactured from February 23, 2005 through August 30, 2006.This Preliminary Evaluation is closed.

RQ10003 · Unintended And Uncontrolled Acceleration

Opened Feb 16, 2010 · Closed Mar 1, 2011

Status: closed (inferred from source dates) · Electrical System:software; Vehicle Speed Control:accelerator Pedal

On February 16, 2010, NHTSA's Office of Defects Investigation (ODI) opened RQ10-003 to determine whether the scope of prior Toyota recalls relating to potential unintended acceleration were sufficiently broad, including, among others, Toyota recalls 07E-082, 09V-388, 10V-017, and 10V-023.NHTSA also requested information regarding potential electronic causes of unintended acceleration in Toyota and Lexus vehicles.I. Pedal Interference from Floor mats, Carpet Covers and Plastic Pads in Carpets.During the RQ10-003 investigation, ODI reviewed a large volume of documents to assess whether additional vehicles should be recalled.Following the agency's analysis, NHTSA requested that Toyota recall additional vehicles.Toyota complied with the agency's request.The details of these recalls are set forth more fully in Toyota's reports to NHTSA pursuant to 49 CFR Part 573.These recalls are as follows:Recall 11V-112: (1) model year (MY) 2004-2006 Toyota Highlander and Highlander Hybrid; and, (2) MY 2004-2007 Lexus RX330,RX350, and RX400h (hybrid model). The total estimated population under this recall is 769,379 vehicles.This recall remedies potential accelerator pedal entrapment caused by a loose floor carpet cover (trim panel). Recall 11V-113: (1) MY 2003-2009 through 2009 Toyota 4Runner; (2) MY 2006-2010 Toyota RAV4; and, (3) MY 2008-2011 Lexus LX570.The total estimated population under this recall is 1,381,000 vehicles.This recall supplements recall 09V-388 and remedies potential accelerator pedal entrapment by an unsecured floor mat.Recall 11V-115: (1) MY 2006-2007 Lexus GS300 (all wheel drive vehicles); and, (2) MY 2006-2007 Lexus GS350 (all wheel drive vehicles). The total estimated population under this recall is 19,647 vehicles.This recall remedies potential accelerator pedal entrapment caused by inadequate clearance between the pedal linkage and a plastic pad embedded in the vehicle's carpet.II. Potential Electronic Causes of Unintended Acceleration.After NHTSA opened RQ10-003, NHTSA launched a ten-month study of potential electronic causes of unintended acceleration in Toyota vehicles.NHTSA launched the study in the spring of 2010 in light of concerns aired in Congressional hearings.NHTSA enlisted engineers at the National Aeronautics and Space Administration (NASA) with expertise in areas such as computer controlled electronic systems, electromagnetic interference and software integrity to assess whether electronic systems or electromagnetic interference played a role in incidents of unintended acceleration in Toyota vehicles.That study has concluded.Two reports are associated with the study and are available on NHTSA's website.NASA's report is entitled Technical Support to the National Highway Traffic Safety Administration (NHTSA) on the Reported Toyota Motor Corporation (TMC) Unintended Acceleration (UA) Investigation, NESC Assessment No. TI-10-00618 (Jan. 18, 2011).NHTSA's report is entitled Technical Assessment of Toyota Electronic Throttle Control (ETC) Systems (Feb. 2011).Both reports should be read in conjunction with each other. As stated in its report, NASA did not find an electronic cause of large throttle openings that can result in unintended acceleration incidents. NHTSA did not find a vehicle-based cause of unintended acceleration incidents other than the physical pedal interference causes that are being addressed by Toyota's recalls. This RQ is closed.
