I AM THE ORIGINAL OWNER OF A 2007 LEXUS RX 400H WHICH HAS NOT BEEN INVOLVED IN ANY ACCIDENTS, AND CURRENTLY HAS APPROXIMATELY 30,000 MILES ON IT. SINCE I PURCHASED THE VEHICLE I HAVE NOTICED AN IRREGULARITY IN MY BRAKING SYSTEM UNDER CERTAIN CONDITIONS, WHICH IS EXACTLY WHAT I HEARD DESCRIBED THIS EVENING ON THE NEWS ABOUT PRUIS HYBRID VEHICLES. IT CAN SIMPLY BE DESCRIBED AS WHEN BRAKING, IF A POTHOLE OR BUMP IN THE ROAD IS HIT, OR SOME OTHER SMALL IRREGULARITY IN THE ROAD SURFACE, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND. THE FEELING IS OF A MOMENTARY LOSS OF CONTROL OF THE VEHICLE, AND HAS HAPPENED WHILE SLOWLY APPROACHING A STOP SIGN OR BRAKING/DECELERATING IN TRAFFIC, BUT NOT TYPICALLY WHEN SLOWING AT HIGHER RATES OF SPEED. I HAVE HAD THESE EXPERIENCES... WHERE I HAVE BEEN SLOWLY APPROACHING A STOP SIGN, BRAKING, WHEN I HAVE HIT A SMALL BUMP, AND WAS NOT ABLE TO STOP THE CAR BEFORE THE STOP SIGN, AND IN SLOW MOVING TRAFFIC WHERE I LOST MOMENTARY CONTROL OVER THE CAR AS THE BRAKES "HICCUPPED" OVER A ROUGH SPOT ON THE ROAD AND LURCHED AT THE CAR IN FRONT OF ME. I WAS JUST ABOUT TO MAKE AN APPOINTMENT WITH MY LOCAL LEXUS DEALER, LEXUS OF AUSTIN (TEXAS) REGARDING MY CONCERN WHEN I SAW THIS EVENING'S NEWS. IT COMPELLED ME TO NOTIFY YOU. IT LOOKS AS THOUGH THIS PROBLEM MAY BE MORE WIDESPREAD WITH ALL TOYOTA PRODUCTS. *JB

I JUST WANTED TO LET YOU KNOW THAT MY WIFE AND I HAVE EXPERIENCED THE ENGINE ACCELERATING ON THE 2007 LEXUS 400H WHILE COASTING TO STOP SIGNS. THIS OCCURRENCE STARTED ABOUT 3-4 MONTHS AFTER WE GOT THE CAR AND DOES NOT OCCUR ALL OF THE TIME. THE GAS PEDAL SEEMS TO OVERRIDE THE ENGINE ACCELERATION PROBLEM, HOWEVER, THE ISSUE SEEMS TO BE SIMILAR TO WHAT OTHERS HAVE SEEN IN OTHER CARS. THIS ISSUE HAS BEEN REPORTED TO THE DEALERSHIP IN THE PAST BEFORE THE RECALLS WITHOUT ANY SATISFACTION. THIS MODEL IS NOT ON THE RECALL LIST, BUT I WANTED TO RAISE THE CONCERN AS IT SEEMS TO BE A PROBLEM SIMILAR TO WHAT IS HAPPENING IN OTHER VEHICLES AND MAY HELP TO INDICATE THAT THE TRUE ISSUE MAY NOT BE THE FLOOR MATS OR THE GAS PEDAL DESIGN. MY WIFE IS CONCERNED SINCE THE ENGINE IS ACCELERATING WITHOUT THE GAS PEDAL DEPRESSED. SINCE THE BRAKE IS OVERRIDING THE ACCELERATION, IT WOULD INDICATE TO ME THAT THE ISSUE IS NOT A STICKING GAS PEDAL. *TR

I HAVE A 2007 LEXUS 400H. I HAVE OWNED THE CAR SINCE NOV. 2006. ON TWO OCCASIONS THE LOW TIRE PRESSURE NOTIFICATION WARNING HAS ACTIVATED. ON THE FIRST OCCASION I JUST ADDED AIR TO ALL FOUR TIRES AND THE WARNING LIGHT TURNED OFF. HOWEVER ON THE SECOND OCCASION WHEN I PLACED THE CORRECT AIR PRESSURE IN COLD TIRES AS SPECIFIED BY THE MANUFACTURE AND TRIED TO RESET THE TIRE PRESSURE MONITORING AND REGULATING SYSTEM, THE SYSTEM WOULD NOT ALLOW ME TO DO SO. WHEN I CONTACTED THE DEALERSHIP, I WAS TOLD THAT THE CAR'S TIRE MONITORING SYSTEM WOULD NOT ALLOW THEM TO ACTIVATE THE SYSTEM AT THE CORRECT COLD TIRE PRESSURE WHICH IN THIS CASE IS 30PSI AND THEY HAD TO PUT 4 EXTRA POUNDS OF PRESSURE IN EACH TIRE TO TURN OFF THE WARNING IMAGE ON THE INSTRUMENT PANEL. I FEEL THIS IS UNSAFE AND THE MANUFACTURE SHOULD CORRECT THIS IF THIS IS IN DEED THE PROBLEM. DO YOU HAVE ANY COMPLAINANTS OF THIS NATURE AND CAN YOU ADVISE. *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.
