RQ10003TOYOTA MOTOR CORPORATION02/16/201003/01/2011Unintended and Uncontrolled Acceleration11V112000
 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.

 I purchased my 2009 4runner new last year. from the minute i drove it off the lot i noticed a problem with the transmission. any time the vehicle slows below 15mph and then the accelerator is depressed, the engine revs to a high rpm as if searching for a gear and does not accelerate as commanded. this is very prevalent in slow traffic, slowing for a yield sign or turning corners. the biggest safety concern is in slippery road conditions. when the vehicle finally does find a gear to shift into, it lurches forward. the shifting into gear from a high rpm on slick surfaces could cause the wheels to spin out. i almost experienced a loss of control of the vehicle because of this. i've brought it in to get repaired at the dealership twice. all they do is flash the ecm and the problem persists. most importantly, toyota has acknowledged this exact same problem on the 2010 model by issuing a tsb. (tsb-0166-10) from reading several toyota 4runner forums, this tsb fixes the problem. please put pressure on toyota to issue a fix for the 2009 model before someone gets injured or killed.
