I WAS COMING INTO DEWITT ARKANSAS ON HIGHWAY165 ON 12/13/09 AT ABOUT 12:30PM WITH MY CRUISE CONTROL ON AT ABOUT 60 MPH. I TAPPED THE BRAKE TO DISENGAGE THE CRUISE CONTROL AND SLOWED DOWN TO MAKE A RIGHT HAND TURN INTO AN EXXON MINI MART. MY 2006 TOYOTA 4RUNNER SUDDENLY ACCELERATED AS I ATTEMPTED TO STOP NEAR THE FRONT DOOR. AS I APPLIED PRESSURE TO THE BRAKES I HEARD THE ANTI LOCK BRAKES CLICKING AND SUDDENLY THE 4RUNNER LUNGED FORWARD STRIKING A LARGE POLE THAT WAS IN FRONT OF ME. THE REAR WHEELS WERE SPINNING WILDLY AND THE BACK END WAS BOUNCING UP AND DOWN. THE 4RUNNER WAS BOUNCING TO THE SIDE AND I SLAMMED THE SHIFT LEVER INTO PARK. THE POWER TO THE BACK WHEELS STOPPED. I SAT BACK AND TOOK MY FOOT OFF THE BRAKE PEDAL, THEN I NOTICED THAT THE ENGINE WAS STILL RUNNING WIDE OPEN THROTTLE. I REACHED UP AND TURNED THE KEY OFF. I LOOKED AT THE FLOOR MAT AND IT WAS IN ITS NORMAL LOCATION WITH NO CONTACT WITH THE GAS PEDAL. THE TWO HOOKS WERE ATTACHED HOLDING THE FLOOR MAT IN PLACE. THERE WAS NO WAY IT COULD HAVE BEEN INVOLVED. TWO EMPLOYEES CAME OUT AND ASKED IF I WAS OKAY. I TOLD THEM I WAS OKAY, BUT SCARED TO DEATH. I TOLD THEM I HAD HEARD ABOUT TOYOTAS HAVING A SUDDEN ACCELERATION PROBLEM, BUT I NEVER THOUGHT I WOULD BE INVOLVED IN ONE. I HAD TO WALK AROUND A WHILE TO CALM DOWN. I GOT THE EMPLOYEES NAMES AND PHONE NUMBERS IN CASE I NEEDED THEM. I WENT BACK OUTSIDE AND STARTED THE 4RUNNER UP AGAIN AND IT RAN NORMAL. I DROVE IT TO MY DAD'S AND LEFT IT THERE. I CALLED THE TOYOTA DEALER THE NEXT DAY AND HAD THEM COME PICK IT UP. THE DEALER HAD A LOCAL TECHNICIAN CHECK IT OUT. THEY SAID THEY COULD FIND NOTHING WRONG AND SAID I SHOULD COME AND GET IT. I TOLD THEM THAT WAS UNACCEPTABLE. THEY HAD A REGIONAL SPECIALIZED FIELD TECHNICIAN EVALUATE IT. HE SAID THAT THERE WAS NO SAFETY HAZARD WITH MY 4RUNNER. THE DEALER WANTS ME TO COME AND GET THE VEHICLE. NOTHING HAS BEEN FIXED OR REPAIRED.*TR

SOON AFTER PURCHASING MY 2006 4RUNNER V8 4WD I WAS PULLING MY BOAT AND NOTICED WHEN I WAS COMING TO A TRAFFIC LIGHT AND BRAKING THAT THE ENGINE WAS INCREASING IN RPM AND IT BECAME VERY DIFFICULT TO STOP. HAD THE TRAFFIC IN FRONT OF ME NOT BEEN CLEAR THERE WOULD HAVE BEEN AN ACCIDENT. THIS HAPPENED SEVERAL MORE TIMES OVER THE NEXT FEW MONTHS, OFTEN WHEN PULLING THE BOAT BUT NOT ALWAYS. I LATER REALIZED THAT THE ROOT CAUSE OF THE PROBLEM WAS THE PROXIMITY OF THE GAS AND BREAK PETALS. WHEN I PULL THE BOAT, AND SOMETIME OTHER TIMES, I WEAR FLIP-FLOPS WHICH ARE FAIRLY WIDE AND FLAT. THE FLIP-FLOPS ARE WIDE ENOUGH TO ACCIDENTALLY BRIDGE THE TWO PETALS WHILE DRIVING. MY 2001 4RUNNER NEVER HAD THIS PROBLEM. I HAVE NOT HAD THIS ISSUE RECUR SINCE I STOPPED WEARING FLIP-FLOPS WHEN DRIVING THE 4RUNNER. THE ONLY REASON I AM REPORTING THIS IS THAT I HAVE READ OF SUDDEN ACCELERATION ISSUES WITH TOYOTA'S AND THOUGHT THIS INFORMATION MIGHT HELP THE INVESTIGATION. THIS PROBLEM APPEARED TO BE A SUDDEN ACCELERATION ISSUE SINCE THE RPM'S WENT UP AND THE BRAKES COULD NOT STOP THE VEHICLE. I DON'T KNOW IF OTHER TOYOTA'S HAVE THE SAME PROXIMITY ISSUE BETWEEN THE BRAKE PETAL AND GAS PETAL. WE HAVE NOT SEEN THIS SAME ISSUE ON OUR 2004 SIENNA. *TR

I OWN A 2006 TOYOTA 4-RUNNER AFTER ABOUT 40,000 MILES WE STARTED EXPERIENCING A CLUNKING SOUND AND THE VEHICLE WOULD LURCH FORWARD WHILE TAKING YOUR FOOT OFF THE BRAKE WHILE AT A COMPLETE STOP. I ADDRESSED THIS WITH MY LOCAL TOYOTA DEALER AND AT THE TIME THEY DIDN?T KNOW WHAT IT WAS. THIS PROBLEM PERSISTED FROM A ONCE AND AWHILE ISSUE TO DOING IT EVERY TIME. I SPOKE WITH ANOTHER PERSON WHO HAD A V8 AND THE SAME PROBLEM, TOYOTA FIXED HIS VEHICLE BY INSTALLING A NEW LEXUS DRIVELINE. ONCE I TOLD THE SERVICE CENTER ABOUT THEM FIXING A VEHICLE WITH THE SAME PROBLEM THEY EXPLAINED THEY HAVE BEEN HAVING ISSUES WITH THE DRIVELINE AND THE YOKE ON THESE VEHICLES. THEIR FIX WAS TO LUBE THE DRIVELINE ZERK FITTING. THIS WORKED FOR A FEW WEEKS, BUT THE PROBLEM PERSISTED. WE ARE WORRIED THAT THE CAR WILL EVENTUALLY LURCH FORWARD AND EITHER HIT ANOTHER VEHICLE OR PEDESTRIAN. SINCE MY VEHICLE IS A V6 THEY CAN?T SWAP THE DRIVELINE LIKE THEY DID WITH THE V8. I DON?T WANT TO BE LIABLE FOR A HITTING SOMEONE WITH A VEHICLE THAT IS NOT PERFORMING CORRECTLY. MY VEHICLE DRIVE TRAIN IS STILL UNDER WARRANTY, BUT I CAN?T GET ANYONE TO SAY THEY WILL HONOR THIS ISSUE AFTER I PASS MY WARRANTY PERIOD. I BELIEVE THIS IS A SERIOUS SAFETY DEFECT AND SHOULD BE LOOKED INTO AS SOON AS POSSIBLE. *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).

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.

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.
