Defect investigations

Frame corrosionOpened August 17, 2018, closed March 18, 2022

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 the federal safety agency?s online complaint database. The petitioner submitted a complaint to the federal safety agency documenting his experience (the federal safety agency 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 the federal safety agency 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 the federal safety agency 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. the federal safety agency 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

Unintended and Uncontrolled AccelerationOpened February 16, 2010, closed March 1, 2011

On February 16, 2010, the federal safety agency'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.the federal safety agency 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, the federal safety agency 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 the federal safety agency 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 the federal safety agency opened RQ10-003, the federal safety agency launched a ten-month study of potential electronic causes of unintended acceleration in Toyota vehicles.the federal safety agency launched the study in the spring of 2010 in light of concerns aired in Congressional hearings.the federal safety agency 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 the federal safety agency's website.NASA's report is entitled Technical Support to the federal safety agency on the Reported Toyota Motor Corporation (TMC) Unintended Acceleration (UA) Investigation, NESC Assessment No. TI-10-00618 (Jan. 18, 2011).the federal safety agency'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. the federal safety agency 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.

What component or system failed or malfunctioned, and is it available for inspection upon request? Response: Frame, Suspension, Airbags / Yes it is available for inspection. How was your safety or the safety of others put at risk? Response: Safety was put at risk due to frame & suspension failure due to severe rust. Also due to failure of deployment of AirBags. Rusted Frame Failure subsequently caused safety of Injured Party and other motorists to be at risk due to the Injured Party’s 4Runner to dart across oncoming lane of traffic with no warning other than a swaying motion felt immediately before losing control. Once the Injured Party lost control of the 4Runner it crossed into oncoming traffic, progressing into the drainage ditch on the oncoming traffic side of highway. Once the 4Runner impacted the drainage ditch at a 90° angle, the 4Runners momentum dispersed by causing the 4Runner to overturn 3 times landing on its wheels in the adjoining field. Has the problem been reproduced or confirmed by a dealer or independent service center? Repaonse: Independent Service Center has confirmed the problem with the Rusted Frame, Rusted Suspension, and Air Bag failure. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Response : Yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Repaint: No warning lamps prior to failure. Symptoms indicative of failure were an unknown minor swaying sensation while driving. Injured party was under the impression that there may have been a tire low on air, which was discovered to be incorrect later.

2004 Toyota 4Runner SR5 - Frame rust: currently not drivable due to complete breakage from the rust. Driving 2 hours home on the highway I almost lost control, pressing/releasing the brake and/or gas pulls the steering side to side and sways the truck (fish tail) due to damage from the frame rust/breaking. There is no control of the rear end. Truck was in great condition prior to the frame snapping. Vehicle has been inspected by multiple mechanics (including Firestone, Welding/fabricating Auto Repair shops and small owned mechanic shops), possibly won’t be able to weld due to the amount of rust. Firestone won’t perform any service if the vehicle needs to go in the air (tires, oil..etc) due to frame rust. This has been a huge problem with Toyota, they addressed other models around the same year but excluded the 4Runner for unknown reasons. The dealership will not address the issue unless instructed by corporate. This problem jeopardized my safety and the safety of others around while I was driving at highway speeds, there was no warning when it occurred. Vehicle is available for inspection any time, as it currently is not going anywhere without a tow.
