TL*THE CONTACT OWNS A 2003 TOYOTA 4RUNNER. WHILE DRIVING 30 MPH, THE STEERING WHEEL SHOOK VERY BADLY. THE CONTACT PULLED THE VEHICLE OVER BECAUSE HE THOUGHT HE HAD A FLAT TIRE, BUT THAT WAS NOT THE CASE. THE VEHICLE WAS TAKEN TO HAVE THE TIRE PRESSURE CHECKED AND THEN TO THE DEALER FOR INSPECTION. THE SHAKING ONLY OCCURS WHILE DRIVING OVER 30 MPH. THE CONTACT STATED THAT THERE WAS A RECALL FOR THIS VEHICLE. THE DEALER CHECKED THE RECALL DATABASE, BUT FOUND NO RECALLS. THE VEHICLE IS CURRENTLY AT THE DEALER FOR INSPECTION. THERE IS A RECALL FOR THE 2001-2002 TOYOTA 4RUNNER REGARDING THE SUSPENSION AND THE CONTACT BELIEVES THAT THE SAME FAILURE IS OCCURRING ON HIS VEHICLE. THE FAILURE MILEAGE WAS 71,100 AND THE CURRENT MILEAGE WAS UNKNOWN.

DRIVERS SEAT IS DEFECTIVE. IT ONCE RATTLED AND MOVED ON IT'S OWN (JUST LITTLE BIT). HOWEVER, THE SEAT FRAME HAS NOW COLLAPSED OVER THE TIME PERIOD. (PLEASE NOTE IT HAS BEEN SINKING SLOWLY OVER A LONG TIME PERIOD.. I JUST NOTICED IT IN 2008) THE FRAME MUST HAVE BEEN DEFECTIVE AND/OR IS POORLY DESIGNED. I AM PRESENTLY SITTING ON THE ELECTRONICS BOX WHICH I BELIEVE TO BE THE ELECTRONICS FOR THE SIDE IMPACT AIR BAGS. I HOPE SITTING ON THAT DOES NOT PREMATURELY SET OFF THE AIR BAGS WHICH COULD CAUSE AN ACCIDENT. OR SHORT OUT THE AIR BAGS SO THEY WON'T GO OFF WHEN NEEDED. I WENT TO THE DEALERSHIP A FEW TIMES. I GET THE RUN-AROUND AND NEVER GET A STRAIGHT ANSWER . NOW THEY WON'T RETURN MY CALLS. *TR

I OWN A 2003 TOYOTA 4RUNNER AND HAVE BEEN EXPERIENCING A SULFUR/ROTTEN EGG SMELL SINCE I GOT IT. IT IS INTERMITTENT AND SEEMS TO OCCUR MOST FREQUENTLY UPON ACCELERATION. THERE HAVE BEEN TIMES WHILE DRIVING THAT I GET VERY DIZZY. AFTER RESEARCHING I FOUND THERE A QUITE A FEW COMPLAINTS ABOUT THIS VERY PROBLEM. IT SEEMS ALONG WITH THE SULFUR DIOXIDE THERE IS CARBON MONOXIDE INSIDE THE CABIN, REGARDLESS IF THE WINDOWS ARE UP OR DOWN. TOYOTA'S RESPONSE IS THAT THIS IS DUE TO BAD GAS. I LIKE MY 4RUNNER BUT THERE IS NO WAY I CAN DRIVE IT KNOWING THAT NOT ONLY ME, BUT MY SON ALSO ARE BEING POISONED. TOYOTA MUST BE HELD ACCOUNTABLE AND FIX THIS IMMEDIATELY BEFORE SOMEONE GETS SERIOUSLY HURT!!!! *TR

FROM A COMPLETELY STOPPED POSITION, LETTING OFF THE GAS AND ALLOWING THE TRUCK TO IDLE FORWARD RESULTS IN A KLUNK NOISE WHETHER YOU ACCELERATE OR NOT. AS I HAVE READ, IT IS A PROBLEM WITHIN THE DRIVETRAIN. I TOOK THE TRUCK TO TOYOTA TO HAVE IT LOOKED AT. THEY SAY IT IS BECAUSE THE REAR NEEDS TO BE LUBED WITH EVERY OIL CHANGE AND WAS COMPLETELY DRY. THEY LUBED IT UP AND SAID THE PROBLEM SHOULD IMPROVE WITH TIME. THE TRUCK IS STILL MAKING THE KLUNK NOISE. THE TRUCK HAS ONLY 85K. THIS SEEMS VERY SIMILAR TO THE PROBLEM WITH TOYOTA TUNDRA AND SOME LEXUSES. *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.
