Referring to a 1998 lexus gs300, rear wheel drive car with 84,000 miles. on saturday, june 19, 2010, i was coming to a stop at an intersection with a 2 way stop sign, with my foot on the brake. my car after slowing down a bit, suddenly accelerated, almost resulting in an accident as i 'cruised' across the intersection instead of stopping. i called lexus and they advised that i bring the car in. i drove there about 15 miles, and on the way there i stopped about 100 feet behind another car which was stopped at a red light. i was at a total stop, my foot on the brake, and the car suddenly lunged forward. there was no accident because i was so far behind the car in front of me. i drove to lexus. they examined the car and told me they found nothing wrong, including with the computer. they then took me for a drive, perhaps 20 or 30 minutes, stopping and starting, and the problem could not be duplicated. i was too afraid to drive the car away as this sudden acceleration happened twice that morning, so i bought a new car on the spot. i was of the understanding that the problem of sudden acceleration did not involve the gs series. lexus did allow my gs300 as a trade-in. both times when the car accelerated, i had no distractions and am certain that this description is absolutely accurate. also, i had only the original mats in the car and they were set properly with the hooks through them as they should be. *tr

This letter is to report a very unsafe condition that exists with my 1998 lexus gs 300. on 2/02/03 i was waiting at a car wash in a line of traffic with my foot on the brake, when all of the sudden my engine advanced to what seem like full throttle. the rear tires began to spin on the wet pavement but my full pressure on the brake kept the car from lunging forward. my wife leaned over to see what was going on and saw my foot on the brake and not on the gas! at that time i started to shift the car into neutral but decided it would be best to turn of the ignition. before i got my hand on the key the engine went back to idle! this whole event lasted 5 to 10 seconds. my foot was definitely not on the gas! at that time my wife told me what happened to her the week before this scary event. she was driving down the road at about 55 mph when the car began to accelerate rapidly with out pressing on the gas peddle. she said she had to apply a lot of brake pressure to keep the car from accelerating over the speed limit. this also lasted about 5 to 10 seconds! service from the lexus dealer is great but they told me my car couldn't do that, and that all computers checked out ok! also a factory service rep said this same thing! i explained to them that it did happen and that i was afraid to drive a car that had a mind of its own. their answer was, no error codes in the cars computer so nothing is wrong! this could have been a deadly situation both times! something must get done before someone gets seriously hurt or killed.

For about the fifth time in the past two years, i have experienced an unintended acceleration. as i was pulling into a 7-11 parking lot, the engine revved without my foot on the accelarator and surged forward at which time i applied the brake hard. the car continued to surge forward, restrained, slower by the braking but still moving toward pedestrians and the store. i moved the shifter into park and the revving ceased in about a second or two. the prior four times i was in traffic moving ahead slowly-- stop and go. while stopped, the engine began to rev and the car tried to surge forward with my foot already on the brake. i depressed the pedal harder and the revving stopped in about 5-10 seconds. reported to the dealer first on 01/03/2002. npf.*ak

Since i purchased the car in march 1998, i have had several serious safety problems. one problem that occurs periodically is that the car will accellerate from 2mph to 8/10mph with the slightest touch onthe accellerator (unintended accelleration). the second problem involves absolutely no accelleration from a stopped condition for up to three seconds. the car stands still and does not move at all. *ak

While driving throttle was stuck, causing vehicle to accelerate unexpectedly in which the occupant had to press hard on the brakes in order to slow down the vehicle. consumer turned off vehicle in order to stop,the vehicle was restarted and it was idling at high rpm. turned off the vehicle again and restarted and the vehicle was at normal rpm. vehicle has been to dealer, however dealer unable to determine problem. *ak *sb

At about 3:45 pm, i left my office in rosslyn to get to a dentist appointment. i was heading west on route 50 in the right lane, then moved to the center lane and floored the accelerator to pass a slow moving vehicle that was in the right lane. as i pulled back into the right lane, the car continued accelerating. i hooked my toe under the accelerator pedal to see if it was stuck in a down position. it was not. *ak

While driving at speed of60- 65mph there is vibration in the front end. also, steering wheel vibrates. contacted dealer. and he replaced tires, and did an alignment. in addition, engine will surge and hesitate at times. *ak

At 45 mph vehicle accelerates without control, have to shift to neutral, and turn ignition off. from a stop the car will suddenly accelerates without drivers control. front end shakes at 45 mph and above, has cruise control.

Cruise control failed. yh
