STEERING. LOOSENESS WHEN TURNING LEFT OR RIGHT. DEALER REPLACED PART (45220-48150 SHAFT ASSY) @ A COST OF $387.93 (THIS WITH A 15% DISCOUNT). IN READING YOUR COMPLAINTS FILED, I NOTE THIS WASN'T T/1ST TIME THIS HAS BEEN REPORTED & AS STATED, THERE IS A DEALER SERVICE ADVISORY ON IT. I ALSO TOOK NOTE THAT THERE APPARENTLY HASN'T BEEN ANY ACTION 2 RESOLVE THE MATTER (IE, THE OWNER CONTINUES 2 PAY 4 REPAIRS). SHOULD NOT TOYOTA B REQUIRED 2 COVER THIS TYPE OF REPAIR ? LIKE WE'RE TALKING STEERING HERE. IS IT GOING TO TAKE SOMEONE WHO JUST LET'S THE PROBLEM GO TO THE POINT WHERE HE/SHE LOOSES CONTROL OF THE VEHICLE & THERE IS PHYSICAL INJURY OR DEATH? I WAS HESITANT TO WRITE THIS UP BECAUSE I DON'T SEE WHERE N INVESTIGATION HAS BEEN CONDUCTED (DID I JUST MISS IT?). MY VEHICLE HAS JUST UNDER 55K MILES ON IT (ALL OF THEM ONROAD) &S BEEN MAINTAINED BY THE DEALER. TO ME IT LOOKS LIKE A $$$ MAKER 4 THE DEALER & A CALCULATED DECISION BY TOYOTA THAT ENOUGH OF THOSE REQUIRING THE REPAIR WOULDN'T COMPLAIN; LOOKS LIKE TOYOTA WINS. *TR

I AM THE OWNER OF A 2004 TOYOTA HIGHLANDER 2WD. THIS VEHICLE IS IN EXCELLENT CONDITION, LOW MILEAGE (ABOUT 40,000) AND HAS NEVER BEEN IN AN ACCIDENT. ON APRIL 19, THE VEHICLE STABILITY CONTROL/ANTI-SLIP BUZZER SOUNDED. THE ICON LIT ON THE DASHBOARD, AND THE VEHICLE STARTED TO BREAK AS IF THE CAR WAS SLIPPING. THE ROAD WAS DRY, OUR SPEED WAS EXTREMELY LOW (ABOUT 15MPH), AND THERE WAS NO REASON FOR THIS TO HAPPEN. THANKFULLY, WE WERE JUST OUT OF OUR DRIVEWAY AND COULD TURN SAFELY AROUND THOUGH THE PROBLEM PERSISTED. ON APRIL 20TH, WE PHONED TOYOTA OF KEENE TO MAKE AN APPOINTMENT TO BRING IN OUR VEHICLE. WE WEREN'T THRILLED WITH THE PROSPECT OF DRIVING UNDER THESE CONDITIONS, BUT FIGURED IF WE KEPT TO LOW SPEEDS WE SHOULD BE ABLE TO MAKE IT SAFELY. WE TOOK DOWN THE TOW COMPANY'S NUMBER JUST IN CASE. ON APRIL 21ST, MY HUSBAND SET OUT FOR THE APPOINTMENT FOR REPAIR IN KEENE. ABOUT 10 MILES FROM HOME, THE PROBLEM SUDDENLY WENT AWAY. THE SKID WARNING LIGHT WENT OUT AND THE VEHICLE STOPPED BREAKING AUTOMATICALLY. MY HUSBAND MADE IT THE REST OF THE WAY TO TOYOTA OF KEENE WITHOUT ANY ISSUES. AFTER A TEST DRIVE, THE TECHNICIAN STATED, 'THAT WAS THE SCARIEST TEST I'VE EVER EXPERIENCED,' AS THE PROBLEM HAD RETURNED WHILE HE WAS ON THE ROAD. BUT BY THE TIME HE RETURNED TO THE SHOP AND HOOKED UP THE CAR TO DIAGNOSTIC COMPUTERS, THE PROBLEM HAD AGAIN CEASED. TOYOTA OF KEENE HAS HAD MY VEHICLE SINCE APRIL 21ST, AND HAS BEEN UNABLE TO REPAIR IT OR OFFER ANY SOLUTION TO THIS ISSUE. THEY CLAIM THAT THEY CAN'T REPAIR IT IF THEY CAN'T REPLICATE THE PROBLEM WHILE THE VEHICLE IS HOOKED UP TO COMPUTERS. THOUGH I UNDERSTAND THIS EXPLANATION, IT DOES NOTHING FOR THE SAFETY OF MY FAMILY, AS WELL AS ANYONE ELSE ON THE ROAD. I CONTACTED THE TOYOTA COMPLAINT CENTER AND THEY OPENED UP A CASE NUMBER BUT WERE ESSENTIALLY USELESS IN ASSISTING ME. I DID SOME RESEARCH ON LINE AND FOUND A TECHNICAL SERVICE BULLETIN AS WELL AS CUSTOMER COMPLAINTS ABOUT THIS VERY ISSUE. *TR

WIFE WAS DRIVING ON CLEAN DRY ROAD. SUDDENLY, THE VCS LIGHT AND TRACTION LIGHTS CAME ON THE DASHBOARD WHILE ALARM SOUNDING CAME ON AS WELL. CAR SUDDENLY BRAKED, BRAKES MADE A GRINDING SOUND, AND CAR JERKED TO THE RIGHT. TRIED TO DRIVE FORWARD AND IT WOULD NOT GO OVER 10MPH. IF THE CAR DID, THE ABOVE HAPPENED AGAIN. CAR WAS NOT DRIVABLE, AND WAS TOWED TO THE NEAREST TOYOTA DEALERSHIP. THE SITUATION WAS VERY DANGEROUS, AS THE BEHAVIOR OF THE CAR, NOT CONTROLLED BY MY WIFE, THE DRIVER, COULD HAVE EASILY CAUSED AN ACCIDENT. TURNS OUT, THE DEALERSHIP STATED THE STEERING ANGLE SENSOR WENT ON THE CAR. FIRST...THE CAR ONLY HAS 53K MILES ON IT. THIS IS NOT A 'WEAR AND TEAR' PART. THIS PART SHOULD NEVER GO WITH ONLY THIS MANY MILES ON IT. GARBAGE. SECOND, THE FAILURE OF THIS PART CAUSES A VERY DANGEROUS SITUATION ON THE ROAD, AS ONCE IT GOES, THE DRIVER BASICALLY HAS NO CONTROL OVER THE CAR UNTIL IT SLOWS DOWN TO UNDER 10 MILES AN HOUR. TOYOTA NEEDS TO STAND BEHIND THEIR PRODUCT, FOCUS ON THE SAFETY OF THE PUBLIC, AND ISSUE A RECALL FOR THIS PROBLEM. I'VE RESEARCHED THIS ON THE INTERNET AND THERE ARE MANY, MANY COMPLAINTS AND DOCUMENTED CASES OF THIS SAME PROBLEM HAPPENING ON TOYOTA VEHICLES. THE DEALERSHIP FIXED THE PART FOR $700. RIP OFF. *TR

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.

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.
