RQ10003TOYOTA MOTOR CORPORATION02/16/2010UNINTENDED ACCELERATION
 On september 26, 2007, toyota filed a defect information report and notified nhtsa that some of its model year (my) 2007 and 2008 lexus e350 and toyota camry vehicles could experience unintended and uncontrolled acceleration due to interference between the optional all weather floor mat offered on those vehicles and the vehicles' accelerator pedal.this decision was influenced by an office of defects investigation (odi) engineering analysis.this recall was designated 07e082.two years later, on october 5, 2009, toyota filed a defect information report and notified nhtsa that a number of its my 2004-2009 lexus and toyota vehicles may also experience unintended and uncontrolled acceleration due to interference between the accelerator pedal and the driver's floor mat.this recall was designated 09v388.several months later, on january 27, 2010, toyota filed an amended, or supplemental, defect information report and expanded the population of vehicles to include additional my 2008-2010 toyota and lexus vehicles.since this expansiontook place in a different calendar year, this recall was designated 10v023.separately on january 21, 2010, toyota filed a defect information report and notified nhtsa that certain toyota vehicles and certain pontiac vibe vehicles contained a safety defect in the accelerator pedal assembly that may cause the accelerator pedal to become harder to depress, slower to return, or in the worse case, mechanically stuck in a partially depressed position.nhtsa designated this recall 10v017.in total, the four recalls cover over 7.6 million toyota and lexus vehicles as well as the pontiac vibe product made by new united motor manufacturing, inc., a venture of toyota and general motors corporation.nhtsa requires additional information from toyota to more fully understand and evaluate, among other things, whether the scope of the recalls identified above (makes, models and model years) is sufficiently broad.the agency is seeking to determine whether toyota viewed the underlying defects too narrowly as interference between the accelerator pedal and the driver

 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.
