WHILE DRIVING, THE CEL (CHECK ENGINE LIGHT) CAME ON AND THE VSC TRAC AND VSC OFF LIGHTS CAME ON AS WELL. APPARENTLY TOYOTA DISABLES VSC WHEN THE CEL IS TRIGGERED. IN MY CASE, THE 2 TIMES IT HAS OCCURRED HAS BEEN DUE TO EMISSIONS RELATED FAILURES (1ST TIME THE CAT FAILED, 2ND TIME ONE OF THE O2 SENSORS FAILED). IN THE 1ST CASE, I IMMEDIATELY TOOK THE VEHICLE TO THE DEALERSHIP AS I WAS APPROACHING THE END OF THE EMISSIONS WARRANTY. THEY MADE THE REPAIRS AND CLEARED ALL THE CODES SO WASN'T AWARE THAT THE VSC SYSTEM WAS ACTUALLY DISABLED. THE 2ND TIME (O2 FAILURE) I REPLACED THE FAILED O2 SENSOR, THE CEL HAS CLEARED, HOWEVER THE VSC LIGHTS ARE STILL ON AND VSC IS DISABLED. I HAVE SERIOUS CONCERNS THAT TOYOTA DISABLES KEY SAFETY SYSTEMS DUE TO EMISSIONS RELATED FAILURES ESPECIALLY GIVEN THE INHERENT STABILITY PROBLEMS WITH SUV'S. IF I'M ON A TRIP WITH MY FAMILY AND AN O2 SENSOR FAILS, OR A CATALYTIC CONVERTER FAILS, OR THE GAS CAP FAILS, KEY SAFETY SYSTEMS THAT HELP KEEP MY FAMILY AND I SAFE SHOULD NOT BE DISABLED! I THINK THIS DESERVES AN INVESTIGATION. *TR

THE EVENING OF 8/10/11 AS I WAS LEAVING WORK, I TURNED THE VEHICLE ON AND A HIGH PITCHED ALARM-TYPE SOUND STARTED; VSC LIGHT, BRAKE LIGHTS CAME ON. AT THIS POINT, I ASKED A NEAR BY SUPERVISOR TO TAKE A LOOK AT THE VEHICLE; UPON INSPECTION HE DID NOT FIND ANYTHING OUT OF PLACE. HE TEST DROVE THE VEHICLE AROUND A COUPLE OF PARKING SPACES AS I WATCHED. HE STOPPED THE VEHICLE AND ASKED IF I HAD BEEN HAVING BRAKE ISSUES. HE THEN ASKED ME TO TEST IT TO SEE IF MY BRAKES NORMALLY RESPONDED AS THEY DID WITH HIM. WHEN I GOT INTO THE VEHICLE TO TEST DRIVE, I ALSO WENT ACROSS A FEW PARKING SPACES BUT WHEN I GOT READY TO BRAKE, THE BRAKES TOTALLY FAILED. THE CURB OF THE END PARKING SPACE STOPPED THE VEHICLE, IT CAME TO REST AND THE TRUCK WAS LATER TOWED TO TOYOTA DEALERSHIP. ON 8/11/11, TOYOTA DEALERSHIP CALLED ME AND STATED THAT THE SKID CONTROL ACTUATOR/ECU ASSEMBLY NEEDED TO BE REPLACED WHICH WOULD COST $3,000.

WARNING LIGHTS BEGAN COMING ON AROUND 60,000 MILES OR SO. STARTED WITH THE LOW TIRE PRESSURE LIGHT & NOW HAS PROGRESSED TO THE VSC ON, VSC OFF, ABS WARNING LIGHTS BEING ON ALL THE TIME AND THE LOW TIRE PRESSURE LIGHT IS STILL ON. I HAVE TAKEN THIS VEHICLE INTO 2 DIFFERENT DEALERS TO BE FIXED FOR 40,000 MILES OR AROUND 3 YEARS WHICH AMOUNTS TO MULTIPLE TRIPS TO THE DEALER, WAITING WHILE THEY WORK ON IT OR GOING WITHOUT A VEHICLE FOR DAYS AT A TIME WHILE THEY TRY TO FIGURE OUT WHAT IS WRONG. THEY HAVE REPLACED ABS SENSORS, ENGINE COMPUTERS, BRAKES, SPEED SENSOR WIRES, RESET COMPUTERS, ORDERED NEW VALVE STEMS FOR THE TIRES. I CAN GET ONLINE & FIND THOUSANDS OF COMPLAINTS REGARDING THE SAME ISSUE IN TOYOTAS & LEXUS VEHICLES SINCE AT LEAST 2001. THE DEALERSHIPS LOOK AT ME LIKE I AM THE VERY FIRST & ONLY PERSON TO EVER MENTION THESE PROBLEMS. THE SOLUTIONS ONLINE HAVE RANGED FROM DEFECTIVE MASTER CYLINDER/BRAKE BOOSTER ASSEMBLY, FAULTY IGNITION COIL, O2 SENSORS, VSC COMPUTERS, CATALYTIC CONVERTERS & BRAKE PEDAL SWITCHES. ALSO PROBLEMS WITH THE EXHAUST SYSTEM & ACCELERATION MODULE UNDER THE CONSOLE WAS LISTED AS FIXING THESE ISSUES. WHY HAS THIS ISSUE NOT BEEN ADDRESSED AND/OR FIXED IN 8 YEARS ? THERE HAVE BEEN TIMES WHEN MY BRAKES DID NOT WORK, TIMES WHEN THEY BARELY WORKED, TIMES WHEN I PUT THE BRAKES ON & IT ABRUPTLY PULLS TO THE LEFT OR RIGHT & A COUPLE OF TIMES WHEN MY VEHICLE WOULD NOT ACCELERATE AS I WAS PULLING ACROSS TRAFFIC. AS I READ OF THESE "FREAK" ACCIDENTS LATELY WITH TOYOTAS, I HAVE TO WONDER IF THEY REALLY ARE "FREAK ACCIDENTS". I DO NOT WANT MY FAMILY OR MYSELF TO BE ONE OF THE TOYOTA FATALITIES THIS YEAR OR ANYTIME. WHEN IS SOMETHING GOING TO BE DONE ? HOW MANY MORE INNOCENT PEOPLE HAVE TO DIE ? *TR

THERE IS A DELAY AND THEN A SUDDEN AND ABRUPT ACCELERATION IN THE VEHICLE A 2004 TOYOTA SUV, VIRTUALLY EVERY TIME DURING SLOW DOWNS IN TRAFFIC AND WHEN MAKING TURNS. THIS CAUSES THE VEHICLE TO JERK AND HAS CAUSED A HOT BEVERAGE TO SPILL ON THE DRIVER, NEARLY CONTRIBUTED TO AN ACCIDENT WHEN THE VEHICLE FAILED TO ACCELERATE WHILE CHANGING LANES, AND WITH PASSENGERS IN THE VEHICLE AT THE TIME CAUSED THE VEHICLE TO SPIN OUT WHILE MAKING A TURN ON A WET ROAD SURFACE - HAD THERE BEEN ANOTHER VEHICLE AT THE INTERSECTION AT THE TIME A CERTAIN COLLISION WOULD HAVE OCCURRED. THE RESULT IS THAT I MUST CONSTANTLY NEGOTIATE THE DEGREE OF PRESSURE ON THE ACCELERATOR IN STOP AND GO TRAFFIC AND WHEN MAKING TURNS. DESPITE ALTERING MY DRIVING HABITS I AM NOT ALWAYS ABLE TO PREVENT THE VEHICLE FROM JERKING AND THE SUDDEN ACCELERATION. THIS PROBLEM IS EXTREMELY FRUSTRATING AND HAS BEEN A DETERRENT FROM LETTING OTHERS DRIVE THE VEHICLE AND BECAUSE OF SAFETY CONCERNS WILL BE A PROHIBITIVE FACTOR IN PERMITTING MY DAUGHTER TO DRIVE THIS VEHICLE WHEN SHE REACHES DRIVING AGE. ULTIMATELY THE VEHICLE WAS CHECKED BY THE DEALER WHERE IT WAS PURCHASED AND THERE DOCUMENTED RESPONSE IS AS FOLLOWS: CONDITION IS NOT ABNORMAL FOR THIS MODEL VEHICLE. BELIEVE DELAY AND HARSHNESS UPON ACCELERATION ATTRIBUTABLE TO DRIVE LINE LASH AND ENGINE LAG DUE TO ELECTRONIC THROTTLE CONTROL. COMMENTS AS A RESULT OF FURTHER PHONE CONVERSATIONS WITH CUSTOMER SERVICE AT THE DEALER WERE ABOUT DESIGN FLAW, WARRANTY NOT APPLICABLE IN THIS SITUATION, NO REPAIR .CURRENTLY AVAILABLE, COULD NOT CORRECT THE PROBLEM - EVEN IF I WERE TO PAY, AWARE OF THE PROBLEM AND CONCERNS BY OTHER DRIVERS, WOULD NOT PROVIDE ANY FURTHER DOCUMENTATION OR ASSISTANCE. *AK

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.
