NO EVENTS LED UP TO THE FAILURE. WIFE DROVE CAR, BRAKE WARNING COMES UP ON DASHBOARD, SHE PULLED OVER. WIFE CALLED ME ON CELL. I THOUGHT IT W THE PARKING BRAKE. I TOLD HER TO MANIPULATE TO CLEAR THE WARNING TO NO AVAIL. THEN I TOLD HER TO OPEN THE HOOD TO LOOK AT THE BRAKE CYLINDER. THE BRAKE CYLINDER HAD DISCONNECTED FROM ITS HOLDER. A SINGLE PIN HOLDS IT IN PLACE. THIS PIN APPARENTLY BROKE CAUSING THE CYLINDER TO FALL OVER AND RELEASE THE BRAKE FLUID. THE CYLINDER WAS LAYNG OVER ON ITS SIDE DANGLING BY TWO WIRES. MY WIFE WAS ABOUT 80 MILES FROM HOME VISITING HER PARENTS. SHE THOUGHT SHE COULD DRIVE HOME SO IT COULD BE REPAIRED BY OUR DEALER, DAYTON TOYOTA IN DAYTON, NJ. I TOLD HER NOT TO DRIVE GIVEN THAT THERE WAS NO BRAKE FLUID. IF SHE HAD DRIVEN HER STOPPING DISTANCES WOULD HAVE BEEN A LOT LONGER. WE CONTACTED AAA THEN A LOCAL TOYOTA DEALER - STAR TOYOTA OF BAYSIDE, NY. THEY ARRANGED FOR A FLATBED TO BRING THE CAR TO THE DEALERSHIP. THE INCIDENT HAPPENED ON A SUNDAY SO IT STAYED AT A AAA SERVICE STATION OVERNIGHT. STAR TOYOTA NOTED THAT THEY WOULD WORK ON IT RIGHT AWAY SO MY WIFE COULD DRIVE HOME. THEY DIDN'T WORK ON IT UNTIL WEDNESDAY WHEN I HAD TO GO GET THE CAR. STAR REPLACED THE CYLINDER SUB ASSEMBLY, BLED THE SYSTEM AND REPLACED THE FLUID. MY CONCERN IS HOW MANY OTHER 2004 TOYOTA HIGHLANDERS ARE OUT THERE WITH THIS TYPE OF DEFECT. AS NOTED THERE WAS NO REASON FOR TEH FAILURE OF THE PIN HOLDING THE BRAKE FLUID CYLINDER. I THINK THERE SHOULD BE A WARNING TO DEALERS TO CHECK FOR THIS PROBLEM.

I OWN A 2004 HIGHLANDER LIMITED, V6, 5-SPEED AUTOMATIC. WHEN DECELERATING AND THEN ACCELERATING, THERE IS A 1 TO 2 SECOND HESITATION BEFORE THE CAR MOVES AGAIN. THIS HAPPENS EVERY TIME. THIS INACTION BY THE VEHICLE IS A SAFETY HAZARD, ESPECIALLY WHEN MERGING ONTO A FAST-MOVING FREEWAY. NOTE: THIS HESITATION DOES NOT OCCUR IF YOU COME TO A COMPLETE STOP. I DID A WEB SEARCH TO SEE IF ANYONE ELSE EXPERIENCED THE SAME PROBLEM, AND I FOUND A LOT OF COMPLAINTS (YOU NEED TO ADD "WEB SEARCH" TO YOUR "SOURCE" LIST BELOW). SO IT'S NOT JUST MY VEHICLE. THIS DESIGN FAULT IS EVIDENT ON ALL TOYOTAS WITH THE 3.3 LITER, 5-SPEED AUTOMATIC. EVIDENTLY THE LEXUS ES330 AND RX330 HAVE THE SAME PROBLEM. I ALSO HAVE A FRIEND WITH A 2004 SIENNA THAT HAS THE SAME PROBLEM. WHEN I TOOK MY CAR INTO THE TOYOTA DEALERSHIP TO COMPLAIN, THEY SAID IT WAS THE ELECTRONICALLY-CONTROLLED TRANSMISSION, AND THAT "IT WAS DESIGNED THAT WAY." I ASKED ABOUT REPROGRAMMING THE FLASH MEMORY OF THE CONTROLLER INVOLVED AND THEY SAID THERE WAS NO UPDATED SOFTWARE, THERE WAS NOTHING THEY COULD DO. SO, I GUESS IT'S UP TO YOU TO GET TOYOTA TO DO SOMETHING. I SEE HERE ON YOUR SITE, THAT THERE HAVE BEEN A LOT OF OTHER SIMILAR COMPLAINTS. THIS IS A REPEATABLE, MEASURABLE SYSTEM FAULT. JUST TAKE A TOYOTA HIGHLANDER WITH A V6 OUT FOR A DRIVE. THEN SLOW DOWN A BIT, THEN ACCELERATE AS YOU WOULD NORMALLY. THE CAR WILL HESITATE. EVERY TIME. NOW DO THIS WHILE YOU'RE MERGING ONTO A FAST-MOVING FREEWAY. WHEN IT HESITATES, YOU'LL DO AN "OH,?!@#$%" AND ACCELERATE HARDER, AT WHICH POINT THE TRANSMISSION WILL HESITATE SLIGHTLY AGAIN, THEN SHIFT DOWN. THE ENGINE WILL REV UP AND YOU'LL ROAR OUT ONTO THE FREEWAY LIKE AN IDIOT. PLEASE. DO SOMETHING ABOUT THIS BEFORE SOMEONE GETS HURT, IF IT HASN'T HAPPENED ALREADY. *TR

WHILE DRIVING THE NORMAL VIBRATION OF THE VEHICLE CAUSES THE DRIVER'S SIDE VISOR TO FALL DOWN OBSTRUCTING THE VIEW OF THE ROAD. THIS OCCURS FREQUENTLY ESPECIALLY IF THE ROAD IS UNEVEN AND ON THE FREEWAY. THE VISOR CONTAINS A FACTORY GARAGE DOOR OPENER BUILT IN. I AM 6'1" TALL; THUS, THE VIEW OF THE ROAD IS MOSTLY OBSTRUCTED. THIS FIRST OCCURRED AS I WAS DRIVING AT FREEWAY SPEEDS, FORTUNANTLY I WAS NOT INVOLED IN AN ACCIDENT. IF I WAS IN HEAVY TRAFFIC THERE WAS A GOOD CHANCE OF THIS CAUSING AN ACCIDENT. I HAVE CONTACTED TOYOTA REQUESTING INFORMATION ON A QUICK FIX, IF APPLICABLE, AND ASKED IF THEY ARE WILLING TO COVER THE COST OF REPAIRING THE DEFECT AS THE WARRANTY OF THE VEHICLE HAS EXPIRED.

ON 3/17/05 I DROVE MY TOYOTA 2004 HIGHLANDER, 2,025 MILEAGE, ONTO A MAIN STREET AT ABOUT 5 MPH. A BEEPING SOUNDED, THE SLIP INDICATOR LIGHT BLINKED SLIGHTLY, AND HORRIBLE CRUNCHING AND CLANGING SOUNDS OCCURED UNDERNEATH THE FRONT OF THE VEHICLE. IT FELT LIKE THE FRONT BRAKES LOCKED UP. I TRIED TO SLOWLY RESUME DRIVING SEVERAL TIMES, BUT THE CAR WAS INOPERABLE AND THE DEALER SENT A TOW TRUCK. THEY SAID IT WAS A PROBLEM WITHIN THE VEHICLE STABILITY CONTROL SYSTEM WHICH INTERACTS WITH THE YAW AND STEERING ANGLE SENSORS, AND THE BRAKE SYSTEM. THERE IS ALSO SUPPOSE TO BE A G-SENSOR ACCORDING TO TOYOTA'S WEB SITE GLOSSARY. (THE DEALER NEVER HEARD OF THE G-SENSOR). THEY SAID IT WAS A BAD STEERING ANGLE SENSOR AND HAD SEEN THIS PROBLEM SEVERAL TIMES. THE SENSOR WAS REPLACED AT THE DEALERSHIP AND SINCE I'VE ONLY DRIVEN IT A FEW MILES, I DON'T KNOW IF IT'S OKAY. WHAT IF THE REPLACEMENT SENSOR IS ALSO BAD? I OFTEN DRIVE IN THE MOUNTAINS ALONE, AND AM EXTREMELY WORRIED ABOUT IT. I AM RETIRED AND BOUGHT THE VEHICLE FOR SAFETY AND SECURITY, RELYING ON TOYOTA'S EXPERTISE, OR SO I THOUGHT! THE VSC SITUATION IS VERY SERIOUS AND SHOULD BE A RECALL ISSUE. I NOW WISH I HAD BOUGHT A HONDA PILOT. *AK

WE PURCHASED A 2004 V6/5 SPEED AUTO 2WD TOYOTA HIGHLANDER IN JUNE, 04. IT HAS A HESITATION PROBLEM WHICH CREATES A SAFETY HAZARD. IT LOSES POWER FOR SEVERAL SECONDS AFTER DECELERATING AND RE- ACCELERATING TO CHANGE LANES OR MAKE LEFT TURNS, THEREBY EXPOSING A POWERLESS, DECELERATING CAR TO ONCOMING TRAFFIC. HAVE TAKEN THE CAR TO THE DEALER TWICE. THEY CLAIM IT IS A DESIGN PROBLEM, THEY CANNOT FIX. THEY SAY IT OCCURS AS A RESULT OF THE ADAPTIVE LEARNING ALGORITHM IN THE ENGINE/TRANSMISSION PACKAGE. CHECK THE EDMONDS TOWN HALL BY SEARCHING FOR "HESITATION" AND YOU'LL FIND IT REPORTED SINCE 12/03 BY HIGHLANDER, CAMRY, SOLARA, LEXUS RX330 AND LEXUS CAMRY EQUIVALENT OWNERS ALL HAVING GOTTEN NO COMMITMENT BY TOYOTA TO FIX IT. THIS IS A SAFETY HAZARD AS DESCRIBED BY THE CLASSICAL DEFINITIONS. IT OCCURS FREQUENTLY (IN MOST VEHICLES AND IN NORMAL OPERATION, AND MORE THAN A FEW OF THE OCCURRENCES WILL EXPOSE THE OCCUPANTS TO SEVERE PERSONAL INJURY. TOYOTA CLAIMS THE HESITATION IS "NORMAL" BECAUSE ALL THE HIGHLANDERS ON THE LOT DO IT--WHICH ONLY REINFORCES THE HIGH FREQUENCY ESTIMATE. FOR WHATEVER REASON, THEY ARE NOT ADDRESSING THIS ISSUE WITH ANYTHING OTHER THAN AN OFFER TO HAVE A TOYOTA REP CONFIRM YOUR CAR HAS IT AND THEN TO TAKE THE ISSUE TO ARBITRATION. ITS TIME FOR YOU TO INVESTIGATE, BEFORE SERIOUS INJURIES OR DEATHS OCCUR. IF WE CAN BE OF ASSISTANCE, PLEASE DO NOT HESITATE TO CONTACT ME. JIM MULLEN. *AK *JB

POWER STEERING AND BRAKES FAILED WHILE DRIVING THE 2004 TOYOTA HIGHLANDER. I HAVE PREVIOUSLY FILED A COMPLAINT HERE AND WITH TOYOTA ABOUT THE CAR CUTTING OUT BETWEEN 20 AND 30 MPH WHICH IS DANGEROUS IN TRAFFIC. THE HESITATION IS MORE PREVALENT NOW WITH 10,000 MILES ON THE VEHICLE EVEN THOUGH AT 700 MILES IT WAS INFURIATING NOT KNOWING IF YOU WERE SAFE TRYING TO MERGE INTO TRAFFIC OR MAKE A LEFT TURN. I DON'T UNDERSTAND HOW THIS COMPANY CAN SELL UNSAFE CARS AND BE ALLOWED TO CHEAT THE PEOPLE WHO PAID FOR THEM. WHEN THE POWER STEERING AND BRAKES FAILED THE CAR HAD TO BE TOWED OF COURSE. HOW LONG BEFORE SOMEONE HOLDS TOYOTA RESPONSIBLE FOR THESE PROBLEMS? HOW DO INDIVIDUALS FIGHT LARGE FOREIGN COMPANIES? ISN'T IT THIS AGENCY'S JOB TO MAKE SURE AMERICAN CONSUMERS ARE SAFE AND TREATED FAIRLY? *JB

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.
