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.

 After noticing ongoing problems with my fuel guage on a 2006 4runner with less than 60k miles, we brought the car into the toyota dealer. when the toyota mechanic pulled the fuel pump assembly out of the gas tank, he discovered a burned and melted wiring harness that sits directly inside the tank. this is a significant safety concern that should be addressed as it deals with an unregulated amount of heat and electricity in close proximity to the gas tank. the mechanic wrote down on my statement that he, found fuel pump wiring has heat damage from [electrical] arcing. i have taken pictures and will send them if requested. thank you.

 Tl*-the contact owns a 2006 toyota 4runner. while reversing out of her garage, the contact engaged the brakes but the vehicle did not slow or respond. the vehicle was towed to an authorized dealership as the vehicle would not move. the dealer stated that the electrical chip had burned out; the vehicle was repaired at that time. the current and failure mileages were approximately 128,000. updated 06/17/10.*lj

 Our 2006 toyota 4runner with a v8 engine has lost accelerator response on two occasions in the first year we have owned it. the check engine, vsc and trac lights all came on and the vehicle would not respond to accelerator inputs. the first occurrence was july 2006 when the vehicle had approximately 3800 miles on it. the throttle control module was changed and the problem seemed to be fixed until it happened again in february 2007 when the vehicle had approximately 9800 miles. the vehicle was in the shop from february until august 2007. toyota replaced the throttle control module again, then the accelerator pedal and the engine control computer, all of which did not fix the vehicle. they finally replaced the entire wire harness in august 2007 which has the vehicle working again. we have asked toyota to re-purchase the vehicle from us because we are concerned about the safety and reliability of this vehicle. if this loss of power were to happen again while on the highway it could cause a serious accident! toyota has refused to re-purchase or replace the vehicle. please look into this problem so that other toyota 4 runner owners and future owners are aware of this potential safety problem with these vehicles.
