PREMATURE TIRE WEAR; MY VEHICLE HAS 37,000 MILES, BUT HAS WORN THROUGH ITS 3RD SET FRONT TIRES. THE FIRST SET I BELIEVE WAS GOODYEAR (TIRES ON CAR AT PURCHASE), SECOND SET KUMHO, AND THIRD MICHELIN ENERGIES. LEXUS CLAIMS IT IS BAD LUCK AND WON'T FURTHER INVESTIGATE TO DATE.

THE 2006 LEXUS RX400H HAS CONTINUOUSLY DEMONSTRATED EXTREMELY EXCESSIVE INSIDE FRONT TIRE WEAR. THE ORIGINAL FACTORY TIRES WERE REPORTED AS WORN OUT AT A 10K MILE DEALER INSPECTION, AND THAT IS AFTER AN INSPECTION AT 5K MILES BROUGHT NO PROBLEMS TO MY ATTENTION. AFTER APPROXIMATELY 50K MILES, ON THE THIRD SET OF TIRES, WITH REPEATED ATTEMPTS TO ALIGN THE FRONT END AND RESOLVE THE PROBLEM, THE ISSUE APPEARS TO REMAIN. THIS VEHICLE DESTROYS FRONT TIRES AT A RATE THAT WILL TAKE CONSUMERS BY EXTREME SURPRISE AND COULD RESULT IN SERIOUS TRAFFIC INCIDENTS DUE TO FRONT TIRE FAILURE. TIRES WITH A LOWER SPEED RATING DO SEEM TO IMPROVE LIFE, AS I HAVE SEEN IN THE LAST SET OF TIRES (EACH SET TRIED HAS BEEN DIFFERENT MANUFACTURER WITH HIGHER LIFE RATINGS); HOWEVER IT DOES NOT RESOLVE THE ISSUE SINCE THE LIFE OF THE TIRES IS STILL BEING DEMONSTRATED TO BE WELL LESS THAN HALF THAT EXPECTED. *TR

ONE ANOTHER VICTIM OF OE TIRES OF INFERIOR QUALITY + ALIGNMENT ISSUES OF LEXUS RX 400H. I AM FILING A FORMAL COMPLAINT AGAINST LEXUS COMPANY. RECENTLY, I DROVE THE SUV (@ 125 MILES AWAY FROM WHERE I LIVE) TO MY DEALER TO GET THE RECALL OF 'POWER STEERING LINK ASSEMBLY' FIXED. THE DEALER PHONED TO TELL ME THAT ALL 4 TIRES MUST BE REPLACED BECAUSE OF BADLY WORN INSIDE TREAD AND STEEL BELT IS VISIBLE ' UNSAFE TO DRIVE. I WAS SHOCKED! WHAT? AT 23,782 MILES? JUST LIKE EVERY OTHER CAR I OWNED BEFORE, I EXPECTED TO REPLACE THEM AT 50-60K MILES. THE DEALER SAID THAT THE OE GOODYEAR EAGLE RS-A 235/55VR18 TIRES USUALLY LAST ABOUT 20K MILES. HE ALSO SAID BECAUSE IT'S A HYBRID CAR!! SHOCKED AGAIN! I WOULD NOT HAVE BOUGHT THAT CAR IF I HAD KNOWN THIS. THE ONLY THING MENTIONED ON THE WINDOW STICKER WAS '235/55VR18 ALL-SEASON TIRES.' I SCANNED THE INTERNET AND LEARNED THAT MANY OUT THERE SHARE THE SAME QUESTION AND CONFUSION. I WAS NEVER INFORMED BY ANYONE OF THE FACT THAT THE EARLIER 400HS HAD ALIGNMENT ISSUES AND THE OE TIRES ON THESE EXPENSIVE 400H SUVS WOULD NEED TO BE REPLACED ROUGHLY EVERY 20K. LEXUS SHOULD HAVE RECALLED ALL THE EARLIER 400HS TO ADDRESS THE ISSUE. ON THE AVERAGE, A CAR WITH AVERAGE QUALITY TIRES WOULD NEED REPLACEMENT ROUGHLY EVERY 50K-60K, WHICH SHOULD BE THE NORM. LEXUS CARS ARE SUPPOSED TO BE LUXURIOUS AS WELL AS RELIABLE, WHY WOULD THE TIRES BE ABNORMALLY WORN JUST ON THE INSIDE EDGE AT JUST 20K MILES? I BELIEVE,I HAVE BEEN MISINFORMED BY LEXUS AND SHOULD NOT HAVE TO PAY FOR LEXUS RESPONSIBILITY OF PUTTING THESE GOODYEAR EAGLE RS-A TIRES ON SUCH LUXURIOUS CARS AND MAKE THE CONSUMERS PAY FOR THE INFERIOR QUALITY. SINCE I WAS TOLD BY THE DEALER THAT THE TIRE PERFORMANCE WAS DUE TO THE SUV IS A 'HYBRID' CAR, THEN IT IS A DESIGN ISSUE THAT WOULD HAVE REQUIRED LEXUS TO INSTALL A DIFFERENT SET OF TIRE. *TR

DP22005 · Pedestrian Alert Sounds

Opened Jan 27, 2023 · Closed Aug 7, 2023

Status: closed (inferred from source dates) · Electrical System:propulsion System

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

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.

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.

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).
