JUST EIGHT MONTHS AFTER PURCHASING FOUR NEW TIRES FROM JUST TIRES, I FELT THE CAR SLIDING IN THE RAIN AND DECIDED TO TAKE MY CAR TO THE TOYOTA DEALERSHIP TO BE CHECKED. I WAS INFORMED THAT THE TIRES WERE COMPLETELY BALD AND TOO DANGEROUS TO DRIVE ON. I LIVE IN LOS ANGELES, I DO NOT DRIVE ON ROAD-WEARING TERRAIN BUT RESIDENTIAL STREETS AND FREEWAYS, SO THERE IS NO OBVIOUS REASON AS TO WHY THE TIRES WERE WORN OUT JUST EIGHT MONTHS LATER. I THEN CONTACTED JUST TIRES DIRECTLY WITH MY COMPLAINT AND BROUGHT THEM THE WORN TIRES. THEIR RESPONSE WAS THAT THE CAUSE WAS DUE TO THE WHEELS NOT BEING ALIGNED. HOWEVER, ON EXAMINING THE ORIGINAL WORK ORDER FROM JUST TIRES, IT SHOWS THAT THE CAR WAS 'CHECKED FOR ALIGNMENT'. IF THE WORK WASN'T CARRIED OUT, I SHOULD NOT BE HELD RESPONSIBLE FOR JUST TIRES SHODDY WORKMANSHIP AND IF THE WORK WAS CARRIED OUT THEN THE FAULT WAS WITH THE ORIGINAL TIRES AND, AGAIN, I SHOULD NOT BE HELD RESPONSIBLE. TO SOLVE THE ISSUE, I WOULD LIKE A FULL REFUND FOR THE TIRES INCLUDING ALL 'EXTRAS' NAMELY $986 (THE COST OF REPLACING THE TIRES AND LABOR). I ORIGINALLY PAID JUST TIRES $612.12 AND THEY HAVE NOW OFFERED ME PALTRY SUM OF $292. *TR

MY 2006 TOYOTA HIGHLANDER OCCASIONALLY FAILS TO ACCELERATE WHILE TURNING. THE MOST PREDICTABLE TIME THIS OCCURS IS WHEN SLOWING TO ALMOST A STOP INTO A LEFT TURN AND THEN ATTEMPTING TO ACCELERATE INTO THE TURN. DEPRESSING THE ACCELERATOR ONLY CAUSES THE VEHICLE TO ACCELERATE SLIGHTLY. I NORMALLY HAVE TO ACCELERATE HARD OR REACCELERATE TO GET THE CAR MOVING. THERE IS ABOUT A 2-3 SECOND DELAY BETWEEN THE TIME YOU DEPRESS THE ACCELERATOR AND WHEN THE CAR RESPONDS IN THE MANNER YOU EXPECT. *TR

EVER SINCE WE PURCHASED OUR 2006 TOYOTA HIGHLANDER WE HAVE RANDOMLY EXPERIENCED ACCELERATION PROBLEMS. AFTER SLOWING DOWN, WE SLOWLY ACCELERATED AND WOULD EXPERIENCE A SUDDEN THRUST BUT COULD SLOW IT DOWN BY LESSENING THE PRESSURE ON THE GAS PEDAL OR BY BRAKING. THIS WOULD HAPPEN AT RANDOM 2 OR 3 TIMES PER YEAR. WE BOTH THOUGHT IT WAS OUR FAULT UNTIL WE READ ABOUT THE TOYOTA ACCELERATION PROBLEMS. NOW, WE DON'T BELIEVE IT IS OUR FAULT AND IS A BUILT-IN PROBLEM. WE RECENTLY HAVE TALKED TO THE TOYOTA SERVICE DEPARTMENT AND THEY REFERRED US TO THE TOYOTA HEADQUARTERS FOR FILING A COMPLAINT WITH THEM. WE WERE TOLD THIS CAR IS NOT ON THE RECALL LIST. SINCE OUR PROBLEM DOES NOT SEEM AS BAD AS OTHER YEAR'S CAR, IT MAY BE THAT THIS IS THE YEAR THE PROBLEM DEVELOPED IN TOYOTA AND GOT PROGRESSIVELY WORST AS ADJUSTMENTS WERE MADE TO THE CAR'S PROGRAMMING OR ENGINE. THE LAST INCIDENT INVOLVING THIS ACCELERATION WAS IN LATE FEBRUARY OR EARLY MARCH, 2010. WE HOPE THIS INFORMATION MAY BE OF SOME HELP TO YOU AND US IN SOLVING OUR PROBLEM. *TR

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.

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.

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).
