NEAR THE END OF AUGUST FOUR WARNING LIGHTS CAME ON AT THE SAME TIME IN MY 2003 4RUNNER. THEY WERE THE VSC TRAC, VSC OFF, ABS AND BRAKE. I SCHEDULED AN APPOINTMENT WITH THE LOCAL TOYOTA AUTHORIZED REPAIR SHOP TO DETERMINE AND FIX THE PROBLEM. THEY LOOKED AT THE VEHICLE AND DISCOVERED SIGNIFICANT RUST AND CORROSION ON THE FRAME, REAR AXLE AND ATTACHED PARTS. I HAVE ASKED FOR AN ESTIMATE TO REPAIR, AND THEY ARE UNABLE TO DO SO AS THERE IS SO MUCH RUST, CORROSION, AND LACK OF MATERIAL TO WORK WITH. I AM THE SECOND OWNER OF THIS VEHICLE. THE FIRST OWNER, A FRIEND OF MINE, HAD THE VEHICLE UNDERCOATED THE DAY AFTER PURCHASE, KEPT THE CAR IN A GARAGE, AND WASHED THE VEHICLE FREQUENTLY INCLUDING THE UNDERSIDE. I PURCHASED THE VEHICLE IN FEBRUARY 2007 WITH 13,750 MILES. IT HAS ALSO LIVED IN A GARAGE HERE. AS OF AUGUST 29, 2013, THE DATE OF THE INSPECTION, THE VEHICLE HAD 24,005 MILES. THE EXTERIOR OF THE VEHICLE IS IN PERFECT CONDITION, AND THE INTERIOR IS THE SAME. HOWEVER, THE UNDERSIDE IS A DIFFERENT STORY. I HAVE CONTACTED TOYOTA AND RECEIVED THIS RESPONSE. "THERE ARE NO KNOWN ISSUES OR CURRENT RECALLS RELATING TO BODY AND FRAME RUST ISSUED FOR YOUR VEHICLE...YOUR VEHICLE IS OUT OF WARRANTY, AND WE WOULD BE UNWILLING TO OFFER YOU ANY COMPENSATION FOR ANY REPAIRS TO THE VEHICLE. WHILE WE UNDERSTAND YOUR DISSATISFACTION WITH THIS DECISION, IT DOES REPRESENT TOYOTA'S FINAL POSITION IN THIS MATTER." *TR

I PURCHASED A BRAND NEW 2003 TOYOTA 4RUNNER IN MAY 2003. IN ONE COLD MORNING OF JAN. 2005, I WAS DRIVING IT IN HIGHWAY THAT WAS STILL COVERED WITH SOME SNOW. ALL OF SUDDEN, AN ENGINE CHECK LIGHT ON THE DASHBOARD WAS AUTOMATICALLY TURNED ON, FOLLOWED BY VSC LIGHTS, INDICATING THAT A VEHICLE SKID CONTROL FUNCTION WAS AUTOMATICALLY TURNED OFF. AT THAT POINT, I COULD NOT DRIVE THE CAR BEYOND 50 MPH, NO MATTER HOW HARD OR FREQUENTLY I PUSHED THE ACCELERATOR PEDAL. I PULLED OVER, RESTARTED, AND RE-ENTERED THE HIGHWAY BUT HAD THE SAME RESULTS. I MANAGED TO DRIVE THE CAR TO A DEALER FOR INSPECTION THE SAME DAY. THE DEALER COULD NOT FIND A CAUSE AND SIMPLY RESET THE COMPUTER CONTROLLER. THIS SEEMED TO HAVE RESOLVED THE PROBLEM AT THAT TIME. HOWEVER, THE ENGINE CHECK AND VSC LIGHT ISSUES RESURFACED ABOUT TWO YEARS LATER. THE DIFFERENCE THIS TIME WAS THAT THERE WAS NO ACCELERATION ISSUE. NO INSPECTION WAS MADE. THE DASHBOARD LIGHTS WERE AUTOMATICALLY TURNED OFF AFTER DRIVING FOR ABOUT A MONTH. IN JAN. 2010, THOSE LIGHTS REAPPEARED AND HAVE REMAINED TURNED ON. NO IMPACT ON ACCELERATION HAS BEEN OBSERVED. *TR

MY 2003 TOYOTA 4RUNNER HAS THE VSC TRAC/TRAC OFF LIGHT ON. EVER SINCE THESE 2 LIGHTS HAVE BEEN ON MY VEHICLE PERFORMANCE HAS BEEN AFFECTED. I HAVE HAD 2 INCIDENTS WHERE MY 4RUNNER FISHTAILS ON MILD WET ROAD, THE 2 TIMES WHEN THIS HAPPENED I WAS ENTERING A RAMP, AND WHILE SLIGHTLY TURNING ONTO THE STREET MY VEHICLE FISHTAILED VIOLENTLY AND TURNING THE VEHICLE FACING THE OPPOSITE DIRECTION AGAINST APPROACHING TRAFFIC. IT WAS A VERY SCARY SCENARIO. I WAS GOING VERY SLOW SINCE IT WAS AN EXITING RAMP WITH A STOP LIGHT SO I HIT ON THE BRAKES TO SLOW DOWN AND MAKE THE TURN AT THE LIGHT ONTO THE STREET AND THIS IS WHAT THE VEHICLE DID...THIS HAS HAPPENED TWICE ALREADY. I'VE SEEN MANY REPORTS ON THE INTERNET FROM MANY PEOPLE HAVING THIS PROBLEM. IS THERE A RECALL IN PLACE FOR THIS TYPE OF PROBLEMS (VSC TRAC/TRAC OFF) ON THE 4RUNNERS?? PLEASE ADVICE. *TR

AFTER REPLACING AN OXYGEN SENSOR SEVERAL TIMES, THE DEALERSHIP FINALLY DISCOVERED THE ROOT OF THE PROBLEM THAT IS MAKING THE OXYGEN SENSOR AND TRACTION CONTROL CIRCUIT SHORT OUT. THE AIR DIVERTOR FLAP INSIDE THE HVAC BOX UNDER THE DASH HAD GREASE APPLIED TO THE FLAP HINGES IN THE FACTORY. DIRECTLY BELOW THE FLAP IS A WIRING HARNESS WHICH DROPS DOWN FROM THE HVAC BOX AND PLUG INTO THE ECU. OVER TIME THE GREASE HAS TRAVELED DOWN THROUGH THE WIRING HARNESS TO THE ELECTRICAL CONNECTION PLUG INTO THE ECU CAUSING VARIOUS CIRCUITS TO SHORT. NO DAMAGE AT PRESENT, HOWEVER VARIOUS SAFETY CIRCUITS SUCH AS TRACTION CONTROL ARE BEING AFFECTED. FURTHERMORE, AS OIL IS COMBUSTIBLE, AN INTERIOR FIRE COULD RESULT FROM THE OIL PENETRATING THE 12 VOLT ELECTRICAL CONNECTION POINT ON THE ECU. THIS ISSUE/ PROBLEM SHOULD BE CONSIDERED HAZARDOUS AND SHOULD BE A RECALL TO REPLACE THE WIRING HARNESS AND ECU AS WELL AS CLEAN THE GREASE OUT OF THE HVAC BOX. *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.
