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 was driving at 55mph when lexus 2007 lexus gs350 suddenly accelerated. the g-forces pinned me to the seat. i was able to shift to neutral and hit brake in less than a second. i then disconnected negative pole on battery for 5 minutes and this resets the computer and surge temporarily ends. the process was described to me by a lexus dealer service manager for a previous lexus i owned.
ELECTRICAL SYSTEM - IGNITION
07/03/20071
 Yesterday my test drive of the 2007 lexus gs 350 awd confirms that like its siblings and cousins (the lexus es 350 and the toyota camry), the gs gives no error warning when the stop button is pressed with the vehicle stopped with the brake applied and the vehicle in drive. there is no chime, no message to put car in park, just total silence. if the driver releases the brake at this point and the car in on an incline, naturally it will roll. other manufacturer's (cadillac, bmw, infiniti) give a chime warning and/or a message to put the car in park. the bmw 535 actually corrects the problem by putting the car in park by itself in this situation. hopefully, no one will be seriously injured or killed before lexus/toyota corrects this problem. why exactly are manufacturers quick to jump on the gimmick bandwagon to sell new products with an unnecessary start/stop button which is capable of defeating the keyed ignition-transmission interlock system which prevents vehicles from being
