VEHICLE IS RUSTING AWAY. FROM THE INSIDE. VERY EVIDENT WHEN THE TOYOTA SPECIALIST WHO WORKS ON THE 4RUNNER HAS TO SERVICE IT AND WORK ON IT. THEY HAVE TAKEN PICTURES AND ARE SUPPLYING US WITH THEM. THEY ARE A NORTH CAROLINA SAFETY INSPECTOR AND CONCERNED ABOUT THE VEHICLE IN A CRASH. THE VEHICLE'S STEERING IS AFFECTED AND OVERALL ABILITY TO CONTROL THE VEHICLE ALONG WITH THE FRAME HOLDING THE VEHICLE PARTS IN PLACE. WE HAVE A 2003 TOYOTA 4RUNNER THAT DOESN'T HAVE ISSUES LIKE THIS ONE. IT HAS SOME RUST BUT NOTHING LIKE THIS. STARTED NOTICING IT IN 2016 AFTER IT HAD REPAIRS DONE WHERE YOU COULD SEE THE INSIDE OF THE BOTTOM AND FRAME PARTS. *THIS 4RUNNER WAS BUILT ON THE TACOMA CHASSIS THAT WAS RECALLED. THIS 4 RUNNER NEEDS TO BE FIXED FOR IT TO BE SAFE. MY SON DRIVES THIS VEHICLE. WELL, HE DID. I CAN'T LET HIM NOW. HE HAS NO VEHICLE. THE PICTURES ARE DISTURBING! ALL OF OUR CARS ARE OLDER AND NEVER HAVE WE HAD AN ISSUE LIKE THIS. THE 2003 4RUNNERS ARE AFFECTED.

EXCESSIVE FRAME AND UNDERCARRIAGE RUST. I HAVE OWNED SEVERAL OTHER CARS OVER 30-40+ YEARS AND THIS 03 4RUNNER HAS THE WORST RUST. INSTEAD OF SIMPLE SURFACE RUST, THIS RUST HAS AFFECTED FRAME WELDS, SUSPENSION MOUNTING POINTS, TOW AND LIFT POINTS. RUSTING PACE IS EXTREMELY FAST MOVING. THERE APPEARS TO BE ONLY A SIMPLE LAYER OF THIN PAINT, WITH NO UNDERCOATING ANYWHERE. THIS 4RUNNER WAS SERVICED REGULARLY, MOTOR IS RUNNING GREAT, BODY AND INTERIOR ARE IN GREAT CONDITION. THIS WAS A GIFT FROM GRANDPA TO GRANDSON, BUT I AM CONCERNED OF SAFETY AND AT THIS POINT RECOMMENDING ONLY LOCAL, UNDER 35MPH TRAVEL ONLY. PROBABLY SCRAP THE CAR SOON AS NOT MUCH TO DO BUT REPLACE FRAME. VERY DISAPPOINTED WITH MISLED CONDITION, OUTSIDE/INSIDE/MOTOR PERFECT, BUT FRAME ROTTING AWAY. MY FAMILY AND FRIENDS HAVE PURCHASED TOYOTAS WITH LITTLE INCIDENT, BUT I WON'T BUY OR RECOMMENDED KNOWING THEY HAVE A LIFE OF ~10YRS.

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.
