I OWN A 2004 TOYOTA 4RUNNER. DUE TO POOR DESIGN DRIVERS SEAT FRAME HAS COLLAPSED. THIS IS A VERY COMMON PROBLEM FOR 2003-2005 4RUNNERS ACCORDING TO MY LOCAL TOYOTA DEALER. SO MUCH SO THAT TOYOTA HAS SEVERAL SERVICE BULLETINS ISSUED REGARDING THE MATTER. I HAD BEEN DRIVING WITH IT BROKEN FOR SEVERAL MONTHS BEFORE REALIZING THE PROBLEM. HAD I BEEN IN AN ACCIDENT WITH THE FRAME BROKEN, THE SEAT WOULD HAVE OFFERED ZERO SUPPORT AND IT'S FAILURE COULD HAVE RESULTED IN DEATH IN AN OTHERWISE SURVIVABILITY ACCIDENT. *TR

THIS INCIDENT WAS 1ST NOTICED 12/9/2009. I STARTED MY CAR IN THE MORNING AND LET IT WARM UP, WHEN I WENT TO GET IN IT A FEW MINUTES LATER, THE HEATER FAN WOULD NOT WORK. SINCE THEN, I FIND THAT THE HEATER FAN WILL WORK OFF AND ON, SEEMS TO BE AFTER VEHICLE HAS WARMED UP A BIT -MAYBE (NOT SURE OF THE RHYTHM OR REASON). I DO NOT FEEL SAFE DRIVING THIS VEHICLE IN COLD WEATHER ESPECIALLY SINCE I HAVE SMALL CHILDREN AND FEAR GETTING STUCK OR STRANDED WITH NO HEAT! I PURCHASED THIS VEHICLE IN DECEMBER OF 2008 AND DROVE IT ALL LAST WINTER WITH NO PROBLEMS-THEREFORE I AM CONCERNED AS TO WHEN AND WHERE IT WILL MALFUNCTION AGAIN. *TR

WARNING LIGHTS BEGAN COMING ON AROUND 60,000 MILES OR SO. STARTED WITH THE LOW TIRE PRESSURE LIGHT & NOW HAS PROGRESSED TO THE VSC ON, VSC OFF, ABS WARNING LIGHTS BEING ON ALL THE TIME AND THE LOW TIRE PRESSURE LIGHT IS STILL ON. I HAVE TAKEN THIS VEHICLE INTO 2 DIFFERENT DEALERS TO BE FIXED FOR 40,000 MILES OR AROUND 3 YEARS WHICH AMOUNTS TO MULTIPLE TRIPS TO THE DEALER, WAITING WHILE THEY WORK ON IT OR GOING WITHOUT A VEHICLE FOR DAYS AT A TIME WHILE THEY TRY TO FIGURE OUT WHAT IS WRONG. THEY HAVE REPLACED ABS SENSORS, ENGINE COMPUTERS, BRAKES, SPEED SENSOR WIRES, RESET COMPUTERS, ORDERED NEW VALVE STEMS FOR THE TIRES. I CAN GET ONLINE & FIND THOUSANDS OF COMPLAINTS REGARDING THE SAME ISSUE IN TOYOTAS & LEXUS VEHICLES SINCE AT LEAST 2001. THE DEALERSHIPS LOOK AT ME LIKE I AM THE VERY FIRST & ONLY PERSON TO EVER MENTION THESE PROBLEMS. THE SOLUTIONS ONLINE HAVE RANGED FROM DEFECTIVE MASTER CYLINDER/BRAKE BOOSTER ASSEMBLY, FAULTY IGNITION COIL, O2 SENSORS, VSC COMPUTERS, CATALYTIC CONVERTERS & BRAKE PEDAL SWITCHES. ALSO PROBLEMS WITH THE EXHAUST SYSTEM & ACCELERATION MODULE UNDER THE CONSOLE WAS LISTED AS FIXING THESE ISSUES. WHY HAS THIS ISSUE NOT BEEN ADDRESSED AND/OR FIXED IN 8 YEARS ? THERE HAVE BEEN TIMES WHEN MY BRAKES DID NOT WORK, TIMES WHEN THEY BARELY WORKED, TIMES WHEN I PUT THE BRAKES ON & IT ABRUPTLY PULLS TO THE LEFT OR RIGHT & A COUPLE OF TIMES WHEN MY VEHICLE WOULD NOT ACCELERATE AS I WAS PULLING ACROSS TRAFFIC. AS I READ OF THESE "FREAK" ACCIDENTS LATELY WITH TOYOTAS, I HAVE TO WONDER IF THEY REALLY ARE "FREAK ACCIDENTS". I DO NOT WANT MY FAMILY OR MYSELF TO BE ONE OF THE TOYOTA FATALITIES THIS YEAR OR ANYTIME. WHEN IS SOMETHING GOING TO BE DONE ? HOW MANY MORE INNOCENT PEOPLE HAVE TO DIE ? *TR

I HAVE A 2004 TOYOTA 4RUNNER AND A FEW MONTHS AGO THE ACCELERATOR PEDAL GOT STUCK UNDER THE RUBBER FLOOR MAT. I PURCHASED THE RUBBER FLOOR MAT FROM A TOYOTA DEALER AND IT WAS MADE SPECIFICALLY FOR THE 4 RUNNER. WHEN THE PEDAL GOT STUCK, THE ENGINE WAS RUNNING WIDE OPEN. I MANAGED TO GET THE VEHICLE IN NEUTRAL AND STOPPED BEFORE HITTING ANYTHING. IT WAS VERY FRIGHTENING. IT APPEARS LIKE THE MAT SLID FORWARD AND THAT WAS WHAT CAUSED THE PEDAL TO GET STUCK. I HAD RECENTLY CLEANED THE MAT AND MAY NOT HAVE HAD IT POSITIONED PROPERLY WHEN I REINSTALLED IT. I THINK THE DESIGN OF THE MAT IS NOT SAFE DUE TO THE THICKNESS OF THE MAT AT THE FRONT NEAR THE PEDAL. FUTURE INCIDENTS ARE LIKELY IF THE MAT IS LOOSE AND SLIDES FORWARD. I DID HAVE A CARPETED MAT UNDER THE RUBBER MAT. THE CARPETED MAT CAME WITH THE 4RUNNER WHEN I BOUGHT THE VEHICLE. THIS LIKELY CONTRIBUTED TO THE RUBBER MAT COMING LOOSE AND SLIDING FORWARD. IF NOT INSTALLED PROPERLY, IT APPEARS LIKE THE CARPETED MAT COULD ALSO SLIDE FORWARD AND MAY CAUSE THE ACCELERATOR TO GET STUCK. *TR

I WAS DRIVING AT ABOUT 35MPH AND HAD TO START BRAKING FOR A VEHICLE THAT WAS SIGNALING A LEFT TURN. I NOTICE THE BRAKES DID NOT FEEL NORMAL AND THAT THE PADS WERE NOT CATCHING ON THE ROTORS. SO I JAMMED ON THE BRAKES AS HARD AND AS FAR AS THEY COULD GO AND AVOIDED HITTING THE OTHER VEHICLE BY INCHES. I CAME HOME AND DECIDED TO INVESTIGATE AND FOUND THAT THE FRONT CALIPERS INNER 4 PISTONS WERE SEIZED. I JUST CHANGED THE BRAKES LAST YEAR AND THEY WERE FINE. BUT NOTICED A SURGE OR SLIPPAGE FORWARD WHEN STOPPED AT A RED LIGHT OR STOP SIGN AFTER A COMPLETE STOP WAITING FOR RIGHT OF WAY. I AM NOW LEAVING THE VEHICLE IN THE DRIVEWAY FOR NOW UNTIL I CAN REPLACE THE CALIPERS. MANY OTHER PEOPLE HAVE COMPLAINED ABOUT THE SAME PROBLEM ON FORUMS JUST LOOK UP 03-09 4RUNNER CALIPER SEIZE. THIS IS VERY DANGEROUS AND COULD CAUSE SERIOUS HARM IN AN AVOIDANCE SITUATION AT HIGHWAY SPEEDS. *TR

DP18002 · Frame Corrosion

Opened Aug 17, 2018 · Closed Mar 18, 2022

Status: closed (inferred from source dates) · Structure:frame And Members

On August 7, 2018, the Office of Defects Investigation (ODI) received a defect petition from Mr. Gary Weinreich alleging premature frame corrosion failure in model year (MY) 2002 - 2006 Toyota 4Runner vehicles. The petitioner based his request upon a corrosion-related front suspension failure he experienced in his MY 2005 Toyota 4Runner, a class action lawsuit settlement involving other Toyota products, and other complaints of underbody corrosion in Toyota 4Runner vehicles that he found in NHTSA?s online complaint database. The petitioner submitted a complaint to NHTSA documenting his experience (NHTSA ID 11098055). On August 17, 2018, ODI opened DP18-002 to evaluate the petitioner?s request. ODI?s evaluation included information provided by the petitioner regarding his vehicle, facts related to the class action lawsuit cited by the petitioner, and consumer complaint data received by NHTSA regarding underbody corrosion in third and fourth-generation Toyota 4Runner vehicles.The undercarriage of the petitioner?s vehicle exhibited severe corrosion damage indicative of seawater immersion. The vehicle?s service history shows that concerns with underbody corrosion were first noted by a Toyota dealer in a multi-point vehicle inspection performed on April 28, 2011. The invoice for that inspection noted ?severe and excessive amount of rust on the undercarriage and on the drive shaft transmission.? Two years later, on October 21, 2013, another multi-point inspection by a Toyota dealer observed further progression of underbody corrosion damage, noting: ?rust on shocks/struts and other components,? ?rust on exhaust system,? ?both splash shields severely rusted,? and ?undercarriage very rusty.? On July 17, 2017, approximately 10 months prior to experiencing the suspension failure incident, an independent repair facility performing routine oil change and brake maintenance informed the Petitioner of a concern with ?excessive frame corrosion? on his vehicle. The service history, severe general corrosion damage, failure age, and environment do not support the petitioner?s allegation of premature corrosion failure.ODI?s analysis of NHTSA complaint data identified fifteen incidents of front lower control arm failure in fourth-generation Toyota 4Runner sport utility vehicles. Two of the failures, including the petitioner?s vehicle, involve vehicles operated in ocean front communities with continuous exposure to aerosolized marine salts and potential exposure to seawater immersion. The remaining thirteen failures all involved vehicles owned or previously registered in states with the greatest use of deicing salts to treat road surfaces in winter months (?Salt states?). On average, the front lower control arm failures occurred after 13.1 years in service in highly corrosive environments. The failure ages and environments do not support the petitioner?s allegation of premature corrosion failure. NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Since the information before the Agency is not indicative of a vehicle-based defect, it is unlikely that any investigation opened because of granting this petition would result in an order concerning the notification and remedy of a safety-related defect. Therefore, upon full consideration of the information presented in the petition and the potential risks to safety, the petition is denied. The denial of this petition does not foreclose the Agency from taking further action if warranted or the p

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.
