WHILE PARALLEL PARKING AND SLOWLY BACKING INTO THE PARKING SPACE, MY VEHICLE SUDDENLY ACCELERATED BACKWARD CRASHING INTO THE VEHICLE PARKED BEHIND ME. MY VEHICLE CONTINUED ACCELERATING BACKWARD INTO THE OTHER VEHICLE AND PUSHED IT BACK EVEN THOUGH I WAS APPLYING THE BRAKES AS HARD AS I COULD. I THEN PUT MY VEHICLE INTO DRIVE WHILE APPLYING THE BRAKES, AND IT IMMEDIATELY LUNGED FORWARD CRASHING INTO THE VEHICLE IN FRONT OF ME. WHILE CONTINUING TO ACCELERATE FORWARD, WITH THE BRAKES APPLIED, MY VEHICLE PUSHED THAT VEHICLE INTO THE VEHICLE IN FRONT OF IT. I THEN TURNED OFF THE IGNITION AND MY VEHICLE STOPPED MOVING. ALL FOUR VEHICLES SUSTAINED DAMAGE. THERE WERE NO OCCUPANTS IN THE OTHER PARKED VEHICLES. REPAIRS TO MY VEHICLE TOTALED $4,076, PLUS $1,444 FOR A RENTAL CAR. I ALSO RECEIVED A SUMMONS FOR CARELESS DRIVING. I BELIEVE THE ACCIDENT WAS THE RESULT OF SUDDEN UNINTENDED ACCELERATION DUE TO A DEFECT IN THE ELECTRONIC THROTTLE CONTROL SYSTEM. *TR

I TOOK MY 2004 TOYOTA HIGHLANDER V6 TO LONGO TOYOTA FOR BRAKE BOOSTER RECALL IN NOVEMBER 2010. THEY KEPT MY CAR NEARLY 7 WEEKS BEFORE REPAIR WAS COMPLETED. A FEW DAYS AFTER PICKING UP MY VEHICLE, WHILE I WAS PARKED DROPPING OFF MY PASSENGER, MOST OF THE CONTROL PANEL LIGHTS ILLUMINATED (BRAKES, ABS, TRAC OFF, VSC, CHECK ENGINE). I REPORTED THIS TO THE DEALER. THEY SAID TO BRING THE CAR BACK. I TOOK THE CAR BACK AND DIAGNOSTIC TESTS WERE RUN AND CONCLUDED THAT A CODE WAS STORED BUT IT WAS NOTHING SPECIFIC THAT HAD FAILED. BRAKE SYSTEM WAS BLED. IN JUNE 2011, THE LIGHT CLUSTER ("CHRISTMAS TREE" IS HOW THE DEALER REFERS TO IT) ILLUMINATED AGAIN WHILE I WAS ATTEMPTING TO PICK UP MY CAR FROM MY LOCAL TOYOTA DEALER (BOB SMITH TOYOTA). AGAIN, THE CAR WAS LEFT. AGAIN IT WAS REPORTED TO ME THAT THE SYSTEM HAD STORED A CODE BUT NO SPECIFIC COMPONENT WAS IN FAILURE AND THE BRAKES WERE BLED. APPROXIMATELY, JULY 20, 2011 AND JULY 23, 2011, THE LIGHTS ILLUMINATED AGAIN, ONLY FOUR OF THEM (TRAC OFF, VSC, ABS, BRAKES). I CONTACTED THE TOYOTA DEALER ON TUESDAY, JULY 26 AND WAS FORCING THE ISSUE ON JULY 29, 2011 AND MADE AN APPOINTMENT FOR AUGUST 1, 2011. ON JULY 31, 2011, THE SAME FOUR LIGHTS ILLUMINATED WHILE DRIVING AND STAYED ON. I STOPPED, TURNED OFF THE ENGINE, RESTARTED THE VEHICLE, AND EXPERIENCED A VERY SPONGY, SQUISHY BRAKE PEDAL. I CONTACTED TOYOTA MOTOR CORPORATION TO FURTHER ADDRESS THE CONCERN OF MY VEHICLE NOW BEING UNSAFE AS A RESULT OF THEIR RECALL. TOYOTA MOTOR CORPORATION WAS VAGUE AND SAID THAT THE MATTER COULD ONLY BE ADDRESSED BY LONGO TOYOTA, THE DEALER THAT PERFORMED THE RECALL, SINCE THE PARTS WARRANTY WOULD ONLY BE WITH THEM. IN CONTACTING BOB SMITH TOYOTA, THE SERVICE ADVISORS SWEARS THAT THE PROBLEM CAN BE RESOLVED BY THEM. IT APPEARS THAT PERFORMING THE RECALL WEAKENED THE INTEGRITY OF MY BRAKE SYSTEM. AS ONE REPRESENTATIVE SAID, "YOU WILL NOT HAVE A CATASTROPHIC FAILURE AND YOU WILL STILL BE ABLE TO STOP. IT WILL JUST TAKE LONGER." *KB

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.

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.

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.
