ONE MORNING OUR TOYOTA HIGHLANDER HYBRID WOULDN'T START. AFTER TRYING TO START IT WITH MY KEY, MY WIFE TRIED USING HERS. IT STILL DIDN'T START. HOWEVER, WE BOTH NOTICED THAT IT WAS MAKING MORE THAN THE USUAL AMOUNT OF BUZZING AND HUMMING SOUNDS. WE BOTH WALKED BACK INTO THE HOUSE, LEAVING THE CAR IN PARK, THE DOORS SHUT BUT THE HOOD UP, TAKING OUR KEYS WITH US. JUST A FEW MINUTES LATER, MY WIFE SAW MOVEMENT OUT THE WINDOW AND WALKED OVER TO SEE WHAT IT WAS. IT WAS THE HIGHLANDER DRIVING ITSELF ACROSS THE LAWN. IT HAD BEEN PARKED ON THE FLAT DRIVEWAY BUT WAS NOW HALFWAY ACROSS THE YARD, HAVING ROLLED OVER A FLOWER PLANTER MADE OF RAILROAD TIES AND WAS HEADED FOR A VERY STEEP HILL. BEFORE EITHER OF US COULD EVEN GET OUT OF THE HOUSE, IT ROLLED OVER THE EDGE OF THE HILL AND DISAPPEARED. A LOUD CRASH LET US KNOW IT HAD COME TO A STOP. (IT HIT A TREE.) THE AIR BAGS DIDN'T DEPLOY AND WHEN WE LOOKED IN THE WINDOW THE GEAR SHIFT WAS IN REVERSE. AFTER BEING TOWED UP THE HILL, IT WAS TAKEN TO A COLLISION REPAIR FACILITY WHERE THE BILL CAME TO ABOUT $11,000. THEN IT WAS TAKEN TO STEVE LOW MIDWEST TOYOTA WHERE WE SOUGHT AN EXPLANATION AND REPAIR. THE DEALER COULD FIND NO DEFECT AND NO REPAIR WAS MADE.

WE'VE OWNED THE CAR FOR ABOUT A YEAR AND THIS PROBLEM HAS HAPPENED TO MY WIFE AND I BOTH WHILE DRIVING. WHILE BRAKING THE BRAKE PEDAL RISES AGAINST YOUR FOOT AND THE VEHICLE SURGES FORWARD THEN AS YOU APPLY MORE FORCE THE PEDAL GOES DOWN AND THE VEHICLE STOPS SUDDENLY. IT HAPPENS INTERMITTENTLY AND THE BRAKE WEAR AND FLUID LEVELS HAVE ALWAYS BEEN FINE, IT SEEMS TO BE A PROBLEM WITH THE POWER ASSIST TO THE BRAKE MAYBE AS THE HYBRID MODEL ENGINE STARTS BECAUSE IT SEEMS TO HAPPEN WHEN BRAKING AFTER COASTING SO THE ENGINE WOULD BE OFF BUT AS THE BRAKES ARE APPLIED ABOUT HALFWAY THROUGH THE NORMAL STOP YOU FEEL THE BRAKE PEDAL GET HARD AND THEN NORMAL AGAIN. DURING THE BRAKE PEDAL HARDNESS THE SPEED OF THE VEHICLE INCREASES WHICH REACTS IN A HARDER BRAKE PEDAL PRESSURE BUT BY THEN THE ASSIST IS BACK AND THE STOP IS SUDDEN. THIS COULD CAUSE BOTH AN ACCIDENT FROM HITTING SOMEONE DURING THE LOSS OF BRAKE AND FROM BEHIND BECAUSE OF THE SUDDEN STOP. *TR

I PURCHASED A 2006 HIGHLANDER HYBRID LIMITED IN SEPTEMBER 2009. FAIRLY OFTEN WHEN I APPLY THE BRAKES AT LOWER SPEEDS, THE SUV SURGES FORWARD LIKE THE BRAKES HAVE RELEASED FOR A MOMENT AND THEN HAVE REAPPLIED. IT IS DANGEROUS AND VERY DISCONCERTING IN CLOSE TRAFFIC OR WHEN GOING AROUND A CORNER OR CIRCLE. ALTHOUGH I HAVE MANAGED NOT TO HAVE A COLLISION, I HAVE COME PRETTY CLOSE WHEN DRIVING WITH A REASONABLE DISTANCE FROM THE CAR IN FRONT. I HAVE DESCRIBED IT TO TOYOTA, WHICH DENIES THERE IS ANY PROBLEM. I HAVE HAD IT SERVICED WITHOUT ANY PROBLEM WITH THE BRAKES BEING IDENTIFIED. THIS IS A PROBLEM THAT IS NOTED BY MANY PEOPLE ON THE INTERNET WHO DESCRIBE THE EXACT PROBLEM WITH MY MODEL AS WELL AS OTHER HYBRIDS MANUFACTURED BY TOYOTA. IT IS A DEFECT THAT COULD CAUSE A SERIOUS ACCIDENT IF EMERGENCY BRAKING IS NECESSARY, WHICH AT SOME POINT WE ALL NEED TO DO TO BE SAFE ON THE ROAD. PLEASE ADDRESS THIS WITH TOYOTA. *TR

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.
