IN FEB 2005 WHILE DOING ABOUT 30 MPH THE VSC LIGHT CAME ON AND STARTED BRAKING, ON IT'S OWN, TO THE RIGHT MAKING IT ALMOST IMPOSSIBLE TO DRIVE. THE NEXT MORNING THE CAR WAS TOWED TO THE TOYOTA DEALER. THE CAR DISPLAYED NO CODES AND THEY SAID THAT THEY HAD CALIBRATED THE STEERING ANGLE SENSOR. WE HAD NO FURTHER PROBLEMS UNTIL MAR 24, 2016. THIS TIME THE VSC INDICATOR CAME ON AT ABOUT 40 MPH. IF I SLOWED DOWN TO ABOUT 20 MPH THE INDICATOR WOULD GO OFF. WE WERE ABLE TO DRIVE THE CAR HOME BUT THE CAR BRAKED, ON IT'S OWN, SEVERAL TIMES. WE HAVE AN APPOINTMENT WITH THE TOYOTA DEALER. I'M AFRAID THAT THE EXPENSE TO REPAIR IT MAY COME CLOSE TO WHAT THE CAR IS WORTH. NHTSA NEEDS TO WAKE UP AND INVESTIGATE THIS ISSUE. IT'S BEEN GOING ON FOR A LONG TIME. THIS PROBLEM COULD RESULT IN A SERIOUS ACCIDENT IF IT OCCURRS AT HIGHWAY SPEEDS. I CAN'T IMAGINE WHAT WOULD HAPPEN IF THE CAR BRAKES ON IT'S OWN AT 75 MPH.

SUMMARY: ON DEC. 30, 2009, I EXPERIENCED A MALFUNCTION IN THE ELECTRONIC STABILITY CONTROL SYSTEM OF MY 2004 4CYL FWD TOYOTA HIGHLANDER SUV. THE MALFUNCTION IS EXACTLY OF THE NATURE DESCRIBED IN THE SUMMARY OF FINDINGS FOLLOWING AN ODI INVESTIGATION OF MALFUNCTIONS IN THE ELECTRONIC STABILITY CONTROL SYSTEMS OF 2003 TOYOTA SEQUOIA VEHICLES(NHTSA CAMPAIGN ID NUMBER 10V176000, NHTSA ACTION NUMBER EA09006). COMPLAINT: THE MALFUNCTION IN MY HIGHLANDER OCCURRED WHEN THE VEHICLE STARTED FORWARD AT VERY LOW SPEED AFTER HAVING BEEN BACKED OUT OF A PARKING SPACE. THE VEHICLE SUBSEQUENTLY HESITATED AND SURGED DURING ACCELERATION AND THE BRAKES WERE AUTOMATICALLY APPLIED AND RELEASED AS IF THE VEHICLE WERE EXPERIENCING A SKID. UNLIKE THE COMPLAINTS CONSIDERED IN THE ODI INVESTIGATION, HOWEVER, THE MALFUNCTION IN MY HIGHLANDER DID NOT SELF-CORRECT. THE VEHICLE WAS SERVICED THE FOLLOWING DAY AT ACTON TOYOTA IN LITTLETON, MA, WHERE THE MALFUNCTION WAS CORRECTED BY RESETTING THE ON-BOARD COMPUTER. THE VEHICLE OPERATED NORMALLY AFTER THE COMPUTER WAS RESET. SINCE ACTON TOYOTA WAS UNABLE TO IDENTIFY A CAUSE FOR THE MALFUNCTION IN THE ELECTRONIC STABILITY CONTROL SYSTEM, I HAD THEM REPLACE THE STEERING ANGLE SENSOR AS A PRECAUTIION ON JANUARY 6, 2010. ACTION: BASED UPON MY EXPERIENCE, I THINK THAT A RECALL OF 2004 4CYL FWD HIGHLANDERS SIMILAR TO THAT FOR 2003 SEQUOIAS SHOULD BE UNDERTAKEN.

THE CHECK ENGINE, VSC, TRAC-OFF LIGHTS APPEARED ON MY DASHBOARD OF MY 2004 TOYOTA HIGHLANDER ON OR AROUND MARCH 7, 2010. ON MARCH 9, I WENT TO MY LOCAL MECHANIC WHOSE TOYOTA DIAGNOSTIC MACHINE INFORMED THEM THAT SINCE THIS VEHICLE HAD UNDER 80,000 MILES - IT WAS STILL COVERED BY MY ORIGINAL WARRANTY. I MADE AN APPOINTMENT WITH SUNRISE TOYOTA, IN OAKDALE, NY WHERE I PURCHASED THIS HIGHLANDER. AFTER SHOWING SUNRISE TOYOTA SERVICE REP: CHARLES SALVATO THE DIAGNOSTIC PRINTOUTS - HE REFUSED TO ADDRESS THE PROBLEM BECAUSE THE PREVIOUS MECHANIC INADVERTENTLY CLEARED THE WARNING LIGHTS. THEY WOULDN'T ACCEPT THE DIAGNOSTIC PRINTOUTS AS PROOF OF A PROBLEM NOR WOULD THEY AGREE TO CHECK-OUT OR RE-RUN THE DIAGNOSTIC TEST. AFTER FORMALLY COMPLAINING, I DID HEAR FROM A BOB JOHNSON AT SUNRISE TOYOTA WHO ASK ME TO STOP IN. WHEN I DID STOP BY, I WAS TOLD HE WAS AT AN ALL DAY MEETING. MY DISTINCT FEELING IS THAT THEY ARE HOPING TO LET THE CLOCK RUN OUT (LET THE MILEAGE GO OVER 80,000) SO THAT NOTHING HAS TO BE DONE. I AM ASKING FOR NHTSA'S ASSISTANCE WITH THIS IMPORTANT SAFETY CONCERN. A CONCERN, I FEEL,TOYOTA IS STILL RESPONSIBLE FOR. THANK YOU FOR YOUR ASSISTANCE IN THIS MATTER. *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

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.
