WHEN DRIVING, ONE TIRE IS COMPLETELY BARELY HANGING ON AS THE FRAME IS FAILING ALL OVER. THE CAR WOBBLES AND SWERVES AND FEELS AS IF IT WILL COME APART AT ANY TIME. THIS FRAME WAS NEVER TREATED PROPERLY WHEN INSTALLED. IF YOU WENT OVER 50 THE CAR COULD FALL APART AND WOULD BE EXTREMELY DANGEROUS.

AFTER I PICKED UP FROM TIRE REPAIR I MADE AN APPOINTMENT FOR AN UNREPAIRED SAFETY RECALL FROM 2012 ON THE ABS AT A LOCAL DEALERSHIP. PRIOR TO SERVICE APPOINTMENT I WAS DRIVING OVER A SPEED BUMP AND THE VEHICLE WOULD NOT DRIVE OVER BUMP, ABS LIGHTS CAME ON AND VEHICLE ROLLED BACKWARDS. HAD TOWED TO TOYOTA DEALER FOR SERVICE(I HAVE RECEIPT FOR TOW) A COUPLE DAYS LATER DEALER SAID RECALL WAS COMPLETED BUT WOULD NOT PROVIDE ANY DOCUMENTATION FOR REPAIRS. THAT DEALERSHIP BROKE A LUG STUD ON THE FRONT TIRE IN BUT DID NOT REPAIR IT. THEY SAID ITS OK TO DRIVE ON 5 LUGS ITS A 6 LUG RIM. I THEN BROUGHT THE VEHICLE TO ANOTHER TOYOTA DEALER FOR REPAIRS BECAUSE THE VEHICLE STARTED ROLLING BACKWARDS ON INCLINES AND NOT ACCELERATING. VERY SCARY BECAUSE I ALMOST ROLLED BACK INTO CARS, ALSO TIRE PRESSURE LIGHT WAS ON BUT ALL TIRES WERE INFLATED. THEY HAD IT FROM 09/12/2016-09/26/2016. UNFORTUNATELY COULD NOT DUPLICATE CONCERN BUT DID REPAIR THE LUG STUD, TIRE PRESSURE SENSOR AND RECALIBRATED THE ABS AND AIRBAG LIGHT(I WAS NOT INFORMED UNTIL PICKED UP ABOUT THE AIRBAG). I ALSO HAD AN OIL CHANGE. VEHICLE HAVING ISSUES AS OF TODAY RIGHT TURNS I HEAR A LOUD CLUNKING SOUND AND WOBBLE WHEN HITTING BUMPS ON HIGHWAY SPEEDS.. THE BALL JOINTS MIGHT BE BAD. I CAN SEE THEM COVERED IN GREASE AND HAVE PLAY. I AM CONCERNED THAT THE VEHICLE IS UNSAFE AND WAS IN AN UNDISCLOSED MAJOR ACCIDENT PRIOR TO PURCHASE. NEXT APP IS NOT UNTIL 10/24. *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

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.

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.
