| RQ10003 | TOYOTA MOTOR CORPORATION | 02/16/2010 | 03/01/2011 | Unintended and Uncontrolled Acceleration | 11V112000 | |
| 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. | ||||||

| The evening of 8/10/11 as i was leaving work, i turned the vehicle on and a high pitched alarm-type sound started; vsc light, brake lights came on. at this point, i asked a near by supervisor to take a look at the vehicle; upon inspection he did not find anything out of place. he test drove the vehicle around a couple of parking spaces as i watched. he stopped the vehicle and asked if i had been having brake issues. he then asked me to test it to see if my brakes normally responded as they did with him. when i got into the vehicle to test drive, i also went across a few parking spaces but when i got ready to brake, the brakes totally failed. the curb of the end parking space stopped the vehicle, it came to rest and the truck was later towed to toyota dealership. on 8/11/11, toyota dealership called me and stated that the skid control actuator/ecu assembly needed to be replaced which would cost $3,000. | |||

| Warning lights began coming on around 60,000 miles or so. started with the low tire pressure light & now has progressed to the vsc on, vsc off, abs warning lights being on all the time and the low tire pressure light is still on. i have taken this vehicle into 2 different dealers to be fixed for 40,000 miles or around 3 years which amounts to multiple trips to the dealer, waiting while they work on it or going without a vehicle for days at a time while they try to figure out what is wrong. they have replaced abs sensors, engine computers, brakes, speed sensor wires, reset computers, ordered new valve stems for the tires. i can get online & find thousands of complaints regarding the same issue in toyotas & lexus vehicles since at least 2001. the dealerships look at me like i am the very first & only person to ever mention these problems. the solutions online have ranged from defective master cylinder/brake booster assembly, faulty ignition coil, o2 sensors, vsc computers, catalytic converters & brake pedal switches. also problems with the exhaust system & acceleration module under the console was listed as fixing these issues. why has this issue not been addressed and/or fixed in 8 years ? there have been times when my brakes did not work, times when they barely worked, times when i put the brakes on & it abruptly pulls to the left or right & a couple of times when my vehicle would not accelerate as i was pulling across traffic. as i read of these freak accidents lately with toyotas, i have to wonder if they really are freak accidents. i do not want my family or myself to be one of the toyota fatalities this year or anytime. when is something going to be done ? how many more innocent people have to die ? *tr | |||

| There is a delay and then a sudden and abrupt acceleration in the vehicle a 2004 toyota suv, virtually every time during slow downs in traffic and when making turns. this causes the vehicle to jerk and has caused a hot beverage to spill on the driver, nearly contributed to an accident when the vehicle failed to accelerate while changing lanes, and with passengers in the vehicle at the time caused the vehicle to spin out while making a turn on a wet road surface - had there been another vehicle at the intersection at the time a certain collision would have occurred. the result is that i must constantly negotiate the degree of pressure on the accelerator in stop and go traffic and when making turns. despite altering my driving habits i am not always able to prevent the vehicle from jerking and the sudden acceleration. this problem is extremely frustrating and has been a deterrent from letting others drive the vehicle and because of safety concerns will be a prohibitive factor in permitting my daughter to drive this vehicle when she reaches driving age. ultimately the vehicle was checked by the dealer where it was purchased and there documented response is as follows: condition is not abnormal for this model vehicle. believe delay and harshness upon acceleration attributable to drive line lash and engine lag due to electronic throttle control. comments as a result of further phone conversations with customer service at the dealer were about design flaw, warranty not applicable in this situation, no repair .currently available, could not correct the problem - even if i were to pay, aware of the problem and concerns by other drivers, would not provide any further documentation or assistance. *ak | |||
