WARRANTY ENHANCEMENT LETTER ZG1 BRAKES FAILED TO ENGAGE FOR THE OWNER AND A THIRD-PARTY MECHANIC. MECHANIC SUGGESTED IT WAS THE ABS SYSTEM AND RECOMMENDED TO TAKE IT TO THE DEALERSHIP. I WAS TOLD OF THE WARRANTY LETTER ZG1; MECHANIC AT DEALERSHIP READ CODES (C1345 AND C1368). THEY ATTEMPTED A RE-CALIBRATION BUT WAS UNSUCCESSFUL. THE RECOMMENDATION WAS TO REPLACE THE ACTUATOR. TOYOTA CORPORATE WAS CONTACTED TO SEE IF THIS WOULD FALL UNDER THE WARRANTY FOR REPLACEMENT. THEY DECLINED REPLACEMENT BECAUSE NONE OF THE FOLLOWING CODES WERE NOTED (C1391, C1252, C1253, C1256). THE WARRANTY VERBIAGE DOES NOT STATE THESE CODES MUST BE INDICATED, BUT INSTEAD SAYS THEY "MAY BE ILLUMINATED". MY ARGUMENT IS THAT IF THERE IS A KNOWN PROBLEM WITH THE ACTUATOR, REGARDLESS OF WHICH CODES WERE ILLUMINATED, THEN THIS COMPONENT SHOULD BE REPLACED BY TOYOTA. AT THIS POINT, I HAVE NOT BEEN TOLD IF IT IS SAFE TO OPERATE MY HIGHLANDER AND DEPEND ON THE BRAKING SYSTEM OR NOT.

BRAKES DISENGAGE MOMENTARILY WHILE BRAKING AT SLOW SPEED. THIS HAPPENS INTERMITTENTLY, AND IS VERY DISCONCERTING. THE OTHER DAY IT HAPPENED ON A HIGHWAY AND CAUSED A REAR END COLLISION AT LOW SPEED. THIS MAY HAVE BEEN AN ACTUAL BRAKE FAILURE, BUT AFTERWARD THE BRAKES WORKED AGAIN. WE ARE NOW AFRAID TO DRIVE THE CAR, AND THE DEALER WON'T DO ANYTHING ABOUT IT BECAUSE HE CAN'T 'REPLICATE' THE SITUATION. ONLINE, HUNDREDS OF PEOPLE HAVE POSTED SIMILAR COMPLAINTS WITH NO REMEDY.

WHILE STOPPING OR STOPPED WITH MY FOOT ON THE BRAKE PEDAL, THERE'S A CLICKING SOUND. I HAVE FOUND THAT IT'S COMING FROM THE ABS BRAKE ACCUMULATOR. THERE HAVE BEEN A COUPLE INSTANCES WHERE I'M PRESSING THE BRAKE PEDAL AND IT STARTS TO SLOW DOWN, THEN FEELS LIKE THE BRAKES RELEASE, THEN GRAB AGAIN SLOWING THE VEHICLE TO A STOP. I'VE ALMOST CRASHED A COUPLE TIMES. I'VE HEARD AND READ OF MANY PEOPLE HAVING THE SAME ISSUE WITH THIS SYSTEM AND SOME HAVE EVEN HAD ACCIDENTS DUE TO THIS. TO ME, IT SEEMS LIKE THIS WOULD BE AN IDEAL CANDIDATE FOR A RECALL, ESPECIALLY SINCE THE REPAIR CAN BE UP TO $4,000 AND MOST PEOPLE DON'T HAVE THAT MUCH THAT THEY CAN JUST PAY OUT AT A GIVEN MOMENT. ALSO, WHEN TURNING THE KEY TO ON, THE ACCUMULATOR HAS STARTED MAKING A LOUD BUZZING NOISE FOR 10-15 SECONDS. PLEASE CONSIDER THIS SYSTEM FOR IMMEDIATE RECALL TO HELP PREVENT ANY MISHAPS.

MY SPEED WAS ABOUT 30 MPH; SPEED LIMIT WAS 40MPH. I WAS DRIVING NORTH-BOUND APPROACHING AN INTERSECTION. UP AHEAD, I SAW THAT TRAFFIC WAS STOPPING AND THE LIGHT WAS RED. I HAD PLENTY OF TIME TO SLOW TO A STOP, AND I STARTED TO EVEN THOUGH I WAS BACK ABOUT 15 CAR LENGTHS FROM THE CARS AHEAD. WHEN I STARTED PUSHING ON THE BRAKE, MY CAR IMMEDIATELY 'DIED' BUT THE CAR KEPT ROLLING FORWARD, EVEN THOUGH I CONFIRMED MY FOOT WAS ON THE BRAKE. I WAS VERY STARTLED THAT THE CAR KEPT ROLLING WITH BRAKE APPLIED. BEFORE I COULD THINK ABOUT WHAT TO DO NEXT, THE CAR THEN RUMBLED AND SHOOK, AND THE ENGINE MADE A REVVING SOUND. THEN THE CAR JUST SPED UP INCREMENTALLY FASTER AND FASTER EVEN AS I DESPERATELY CONTINUED TO SHOVE HARD ON THE BRAKE. I YELLED "WHAT'S IT DOING?' I QUICKLY WONDERED IF I SHOULD PULL THE KEY OUT OF THE IGNITION BUT FELT THAT WAS THE WRONG THING TO DO. AS THE CAR WENT FASTER, I WENT INTO ABSOLUTE PANIC. I COULD NOT STOP THE CAR. I DIDN'T KNOW HOW TO MISS HITTING ANYONE. I WAS DESPERATE TO AVOID CARS, BUT I WAS COMPLETELY UNABLE TO STOP MY CAR EVEN AS I CONTINUED PUSHING HARD ON THE BRAKE. THEN I HIT THE CAR IN FRONT OF ME AT THE LIGHT. I TRULY BELIEVE THIS WAS AN UNINTENDED BRAKE ACCELERATION. I AM DEEPLY COMPELLED TO REPORT THIS SO THAT THE CAUSE AND RESOLUTION MAY BE FOUND BEFORE OTHERS ARE SERIOUSLY HURT OR KILLED. I SUFFERED A FRACTURED BACK AND WAS IN THE HOSPITAL 4 DAYS; AND DRIVER I RAN INTO WAS HURT AS WELL REQUIRING HOSPITAL ATTENTION. BOTH THE 3RD PARTY COMPANY FOR TOYOTA WHO DOWNLOADED THE DATA BOX AND TOYOTA SAY THE BRAKES WERE NOT APPLIED; THAT IS NOT FACTUALLY UNTRUE! THE DATA COMPUTER PRINT-OUT SHOWS WHAT TOOK PLACE PRIOR TO THE IMPACT. IN FACT, IT SHOWS THAT THE ACCELERATOR CONTINUED TO ACCELERATE UP TO THE POINT OF IMPACT WHICH TELLS US THAT THE COMPUTER TOOK OVER THE ACTIONS OF THE CAR AND DISENGAGED THE BRAKES.

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.
