Vehicle Speed ControlCrashInjury

Read full complaint

ON FEBRUARY, 18, 2011 AT APPPROXIMATELY 1:30 P.M. I GOT INTO MY 2004 TOYOTA HIGHLANDER, WHICH WAS PARKED IN A PRIVATE PARKING LOT AT 1 MEETINGHOUSE RD. IN CHELMSFORD, MA. I TURNED THE KEY ON, STARTED THE CAR, AND PUT THE GEAR IN REVERSE TO BACK OUT OF THE PARKING SPACE. AS I TOUCHED THE ACCELERATOR PEDAL WITH MY RIGHT FOOT, THE CAR ACCELERATED UNCONTROLLABLY AT A SPEED THAT DID NOT CORRESPOND WITH THE PRESSURE I HAD PUT ON THE PEDAL. I IMMEDIATELY PUT MY FOOT ON THE BRAKES, BUT THERE WAS NO RESPONSE FROM THE BRAKE SYSTEM. THE STEERING WHEEL WAS TURNED TO BACK OUT IN A COUNTERCLOCKWISE DIRECTION, AND WITHIN NO MORE THAN 4 SECONDS, THE CAR CRASHED INTO A BUILDING APPROXIMATELY 20 FEET FROM WHERE THE CAR WAS INITIALLY PARKED. THE CAR WAS TOTALLY UNRESPONSIVE TO MY EFFORTS TO BRAKE SUBSEQUENT TO THIS SUDDEN AND INEXPLICABLE ACCELERATION. I'M LUCKY I WASN'T KILLED, BECAUSE MY VEHICLE WAS TOTALED. *TR

I OWN A 2004 TOYOTA HIGHLANDER. I HAVE HAD AN OCCASIONAL PROBLEM WITH THE VEHICLE HESITATING AND THEN LURCHING UPON ACCELERATION SINCE I PURCHASED THE VEHICLE. THE PROBLEM IS BECOMING MORE FREQUENT AS THE VEHICLE AGES. I HAVE MENTIONED IT ON SEVERAL OCCASIONS WHEN THE VEHICLE WAS TAKE IN FOR SERVICE BUT THE MECHANIC WAS NOT ABLE TO DUPLICATE THE PROBLEM. I HAVE BEEN USING AN INDEPENDENT MECHANIC FOR THE LAST COUPLE OF YEARS FOR MY REGULAR SERVICE ON THE CAR (THE CAR HAS BEEN A VERY GOOD CAR OTHER THAN THE ACCELERATION ISSUE AND HAS NOT NEEDED ANYTHING OTHER THAN REGULAR SERVICE). I MENTIONED THE PROBLEM TO HIM ON DIFFERENT OCCASIONS AND AT FIRST, HE WAS NOT ABLE TO DUPLICATE THE PROBLEM EITHER. MY HUSBAND MENTIONED IT AGAIN WHEN WE TOOK IT IN FOR THE LAST SERVICE. THIS TIME WHEN THE MECHANIC DROVE THE CAR HE WAS ABLE TO FEEL THE HESITATION AND SUBSEQUENT LURCHING. HE THEN PUT IT ON AN ANALYZER WHICH SHOWED VOLTAGE SPIKES IN THE THROTTLE BODY. HE SAID TO CALL TOYOTA. WE CALLED TOYOTA AND WERE TOLD THAT THE VEHICLE NEEDED TO BE TAKEN TO A TOYOTA DEALER. WE TOOK IT TO A DEALER THIS MORNING AND WERE TOLD THAT THEY COULD NOT DUPLICATE THE PROBLEM AGAIN. I CALLED TOYOTA AND FILED A COMPLAINT (10070906470 AND 1007090670 WERE THE NUMBERS I WAS GIVEN). THEY TOLD ME THERE WAS NOTHING THEY CAN DO UNTIL A TOYOTA DEALER CAN DUPLICATE THE PROBLEM. I HAVE SINCE FOUND HUNDREDS OF COMPLAINTS ONLINE ABOUT THE SAME ISSUE BY OTHER 2004 HIGHLANDER OWNERS. I DON'T KNOW WHERE ELSE TO TURN FOR HELP. *TR

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). PLEASE NOTE THAT THE VIN INFO IS NOT CORRECT. I INSERTED RANDOM NUMBERS BECAUSE I DON'T HAVE THAT INFO IN MY POSSESSION RIGHT NOW AS I AM AT MY WORK DESK. ALSO KEEP IN MIND THAT MY CAR IS A 2004 VIBE. IT DID NOT HAVE THAT OPTION. IN 2/28/08, I HAD AN ACCELERATATION PROBLEM. IF YOU GET IN TOUCH WITH BARSTOW IN POTSDAM NY, THEY CAN VERIFY THIS. THEY HAVE IT ON RECORD. THIS PROBLEM WAS UNPREDICTABLE WHEN IT HAPPENED AND THE LAST TIME IT HAPPENED, I THOUGHT I WAS GOING TO DIE. I COULD NOT GET THE CAR TO STOP AFTER IT ACCELERATED BY ITSELF. I BROUGHT IT TO BARSTOW, EXPLAINED THE SITUATION AND THEY SAID THEY HAD HAD NO OTHER COMPLAINTS SUCH AS MINE. THE MECHANIC THERE UNDID THE CRUISE CONTROL, AND THE PROBLEM WENT AWAY. FIVE MONTHS LATER I HAD HIM PUT IT BACK ON IN JULY. IT COST ME $25 EA. TIME. PLEASE CONTACT KEN MURRAY AT BARSTOW MOTORS POTSDAM NY TO VERIFY ALL OF THIS. I WOULD LIKE TO BE REIMBURSED FOR THE MONEY I HAD TO PAY AS I STRONGLY FEEL THAT THE PROBLEM IS RELATED TO THE ONE THAT TOYOTA IS HAVING NOW WITH ACCELERATION DIFFICULTIES. ALSO, ALTHOUGH I HAVE NOT HAD ANY OTHER PROBLEMS, I WANT TO KNOW WHAT WILL TOYOTA DO IF IT HAPPENS AGAIN. MY VIBE IS A 2004. [XXX] *TR

EVER SINCE I PURCHASED MY HIGHLANDER, NEW, I INFREQUENTLY EXPERIENCE AN UNEXPECTED SURGE IN ACCELERATION WHILE BEGINNING TO ACCELERATE FROM A STOP, OR AFTER SLOWING TO TURN A CORNER. THIS HAS HAPPENED SEVERAL TIMES WHILE TURNING A CORNER. I HAVE BROUGHT THIS UP TO TWO DIFFERENT TOYOTA DEALERSHIPS, IN THE PAST, AND WAS TOLD THAT THEIR ELECTRONIC TRANSMISSION WAS THEIR BIGGEST COMPLAINT, BUT THERE WAS NOTHING THEY COULD DO ABOUT IT. WHILE DESCRIBING THE PROBLEM TO A SERVICE REP AT A DEALERSHIP, A GENTLEMAN, ALSO WAITING FOR SERVICE, INDICATED THAT HE HAD THE SAME PROBLEM WITH HIS NEWER MODEL RAV 4. THIS MAY HAVE HAPPENED FEWER THAN TWO DOZEN TIMES SINCE I PURCHASED THE HIGHLANDER. HAS THIS PROBLEM BEEN BROUGHT TO YOUR ATTENTION, OR DO YOU KNOW IF TOYOTA HAS EVER DEVELOPED A "FIX" FOR THIS? *TR

WE HAVE A 2004 TOYOTA HIGHLANDER, AND WE HAVE HAD SURGES ON THE GAS SINCE WE BOUGHT IT IN 2004. IT USUALLY IS SOMETHING THAT WE CAN CONTROL, AS YOU WILL BE DRIVING ALONG, AND IT WILL SURGE FORWARD A BIT, BUT WE HAVE ALWAYS BEEN ABLE TO APPLY BRAKE AND CONTROL IT. THERE HAS ONLY BEEN ONE INSTANCE WHERE IT SURGED STRONGLY, AND I HAD TO SLAM ON THE BRAKES TO AVOID HITTING THE CAR IN FRONT OF ME. WE TRIED TO SELL THE CAR A COUPLE OF YEARS AGO, BUT THE BUYER TEST DROVE IT, AND NOTICED THE SURGING, ASKED ABOUT IT, AND THEN DECIDED NOT TO BUY IT - SO WE KEPT IT AFTER THAT. WE WERE THINKING IT IS A SOFTWARE PROBLEM, OR SOMETHING.... WE HAVE NEVER TAKEN IT INTO A SHOP TO HAVE IT DIAGNOSED, BUT THOUGHT MAYBE IT WAS IMPORTANT TO MENTION IT, IN CASE OTHER HIGHLANDERS HAVE HAD THE SAME ISSUE. I DIDN'T THINK IT WAS THE GAS PEDAL STICKING, BUT JUST THE GAS SURGING SOMEHOW, BUT MAYBE IT IS RELATED. *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.
