THIS POTENTIAL SAFETY PROBLEM INVOLVES HYBRID INVERTERS IN LEXUS HYBRID VEHICLES. THIS PARTICULAR CASE INVOLVES A 2006 LEXUS RX400H VEHICLE WITH ABOUT 109,000 MILES ON IT THAT HAD RECEIVED ALL RECOMMENDED, SCHEDULED, ROUTINE MAINTENANCE. IN THE COURSE OF NORMAL DRIVING, ALL POWER TO PROPEL THE VEHICLE COMPLETELY AND ABRUPTLY VANISHED. IN ADDITION, THE VEHICLE CONCOMITANTLY LOST POWER STEERING AND SKID CONTROL AS EVIDENCED BY NOTICES ON THE DASH. FORTUNATELY IN THIS CASE, MOMENTUM ALLOWED THE VEHICLE TO COAST TO THE SIDE OF THE ROAD WITHOUT INCIDENT. THE CAR WAS PUT IN NEUTRAL AND MANUALLY PUSHED OFF THE ROAD. LATER IT WAS TOWED A GREAT DISTANCE TO THE DEALER, AT CONSIDERABLE EXPENSE, THE DEALER BEING THE ONLY PLACE CAPABLE OF THIS TYPE OF REPAIR. THE DEALER FOUND THE HYBRID INVERTER FAULTY. NO REASON FOR THE FAILURE COULD BE PROVIDED. THE WARRANTY NO LONGER APPLIED THEREFORE THE COST OF REPAIR WAS QUOTED AS AN ASTONISHING $9,000.00 ! TOYOTA EVENTUALLY AGREED TO PAY THE DEALER FOR THE PART, BUT NOT ITS INSTALLATION. THE FAULTY PART WAS NOT RETURNED. SHOULD THIS TYPE OF INCIDENT NOT PROVE ISOLATED, SUCH ABRUPT AND UNCONTROLLED POWER LOSS RENDERS ALL THESE VEHICLES UNTRUSTWORTHY AT MINIMUM, AND RAISES POTENTIALLY CATASTROPHIC SAFETY CONCERNS DEPENDENT ON CONDITIONS THAT INCLUDE WHERE AND WHEN HYBRID INVERTER FAILURE AND COMPLETE POWER LOSS SUDDENLY OCCURS. *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.

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.
