AS OF THIS COMPLAINT, LEXUS SHOULD NOT BUT STILL IS USING THE GOODYEAR EAGLE RS-A TIRES AS OE TIRES. ON NOV. 30, I TOOK MY 400H TO THE DEALER FOR THE 10K SERVICE, THE SAME PLACE WHERE IT GETS SERVICED EVERY 5000 MILES. THE DEALER PHONED TO TELL ME THAT ALL 4 TIRES MUST BE REPLACED BECAUSE OF BADLY WORN INSIDE TREAD. I WAS SHOCKED! WHAT? AT 19,562 MILES? JUST LIKE EVERY OTHER CAR I OWNED BEFORE, I EXPECTED TO REPLACE THEM AT 40K-60K MILES. THE DEALER SAID THAT THE OE GOODYEAR EAGLE RS-A 235/55VR18 TIRES USUALLY LAST ABOUT 20K MILES. 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.' WE SCANNED THE INTERNET AND LEARNED THAT MANY OUT THERE SHARE THE SAME QUESTION AND CONFUSION. WE WERE NEVER INFORMED BY LEXUS THAT EARLIER 400HS HAD ALIGNMENT ISSUES. LEXUS SHOULD RECALL ALL EARLIER 400HS TO ADDRESS THIS ISSUE. WE WERE NEVER INFORMED THAT THE OE TIRES ON THESE EXPENSIVE 400H SUVS WOULD NEED TO BE REPLACED ROUGHLY EVERY 20K. ON THE AVERAGE, A CAR WITH AVERAGE QUALITY TIRES WOULD NEED REPLACEMENT ROUGHLY EVERY 40K-60K, WHICH SHOULD BE THE NORM. WE BELIEVE THAT WE 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 WE WERE TOLD BY THE DEALER THAT THE TIRE PERFORMANCE WAS DUE TO THE FACT THAT THEY WERE RUNNING A 'HYBRID' CAR, THEN IT IS A DESIGN ISSUE THAT WOULD HAVE REQUIRED LEXUS TO INSTALL A DIFFERENT SET OF TIRES. SOME OF US WOULD HAVE OPTED FOR A DIFFERENT CAR OR EVEN A TOTALLY DIFFERENT MAKE IF IT MEANS PAYING ABOUT $1000 FOR EVERY 20K WE DRIVE JUST ON TIRE REPLACEMENT. WE ARE ALSO EXTREMELY DISAPPOINTED BY LEXUS' INACTION KNOWING SUCH WIDELY-DISCUSSED PROBLEM. LEXUS CARS ARE SUPPOSED TO BE LUXURIOUS AS WELL AS RELIABLE. ANOTHER QUESTION IS, WHY WOULD THE TIRES BE ABNORMALLY WORN JUST ON THE INSIDE EDGE? *TR

PRIOR TO HAVING THE TIRES REPLACED, THERE WERE NUMEROUS OCCASIONS WHERE THE CAR FELT LIKE IT WAS ON THE VERGE OF SLIPPING/SKIDDING OR LOSING GRIP OF THE ROAD. IT WOULD HAVE BEEN TOO LATE IF THERE WERE INJURIES OR DEATHS DUE TO THE UNSAFE QUALITY OF THIS PRODUCT. ON NOV. 30, I TOOK MY 400H TO THE DEALER FOR THE 10K SERVICE. IT WAS THE SAME DEALERSHIP WHERE IT GETS SERVICED EVERY 5000 MILES. THE DEALER PHONED TO TELL ME THAT ALL 4 TIRES MUST BE REPLACED BECAUSE OF BADLY WORN INSIDE TREAD. I WAS SHOCKED! WHAT?

MY WIFE WAS DRIVING ON THE NYS THRUWAY. SHE PULLED OFF AT A REST AREA. SHE WAS FULLY STOPPED WAITING FOR A PARKING SPOT TO OPEN UP WHEN THE STEERING WHEEL BEGAN TO SHAKE VIOLENTLY OUT OF CONTROL. THE FRONT WHEELS WERE OSCILLATING LEFT AND RIGHT IN SYNC WITH THE MOVEMENT OF THE STEERING WHEEL. SHE TURNED THE VEHICLE OFF IMMEDIATELY. AFTER A MINUTE SHE ATTEMPTED TO START IT AGAIN. IT STARTED NORMALLY. AS SOON AS SHE TOUCHED THE STEERING WHEEL, THE SHAKING RESUMED. SHE TURNED IT OFF. BY PUTTING THE CAR INTO NEUTRAL, SOME PEOPLE WERE ABLE TO HELP HER WINCH THE STEERING WHEEL ENOUGH TO PUSH THE CAR INTO A SPACE WHERE IT STAYED UNTIL A TOW TRUCK ARRIVED. SOME BYSTANDERS ?!@#$%. *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.
