 We have experienced on several occassions that vehicle hesitates when trying to accelerate at stop sign or when initialy in start to drive at about 20-30 miles per hour at times for few seconds & at times it rattles 3-4 times. this car was purchased as certified pre-owned from lexus dealer in excellent condition in 2006 that came with extended warranty upto 75000 miles but this problem started with slight & smooth jerk about 3 years back, took it to dealer after noticed for few times to diagnosis. at first instance they could not feel it since it was not consistent but when again complained for second time was told that it could be fuel injectors cloged followed by other list of potential service items we were talking about $1000+ expense which we denied it since we have always maintained our car good & always use 93 or 89 octaine gas with maintenance service as recommended. this one is my wife's vehicle & used to commute to work mostly on express way. we do have couple other issues with this car but not as important. now, lately this hesitation frequency have increased & from what i hear is that we are not alone and this seems to be an ongoing issue with some other es300 owners as well.

 I was driving slowly, less than 10 mph, approaching a red light behind another vehicle. suddenly, my car accelerated forward and could not be stopped by braking. i collided with the rear end of the car in front of me. there were no injuries, but both cars had significant damage. *cn

 The transmission in this car is unpredictable. it jerks, jumps and on occasion lurches ahead. it will hesitate when starting from stand still or when moving ahead at very low speeds. i have repeatedly taken it to the dealer. they have done 2 computer down loads of a supposed fix. the first lasted a day. i've been told to use only premium fuel, as this would help. i've used premium since that time with little change in the cars perfomance. my wife does not want to drive the car because of a near t-bone in a cross pattern traffic. i've had 4 similar experinces. this probem became apparent at about 1000 to 1200 miles and exits tody at about 4000 miles. all of these querky problems exist below 40 miles per hour. if you drive very aggressively (stomp on the accelerator)they aren't evident...to some exte the same is true if you barely depress the accelerator when starting to move.

 There is a pronounced hesitation when the accelerator is floored. this has been there since i leased the car and i do not know if it is due to a transmission lapse or throttle problem. i have had a number of near accidents when i pulled out to pass and there was no acceleration. lexus has acknowledged this problem and offered a fix, but it did not solve the problem. they now say that the car is performing as designed.

 2003 lexus es300 with accelerator pedal, automatic transmission, and vehicle speed control issues. consumer states that the when trying to accelerate from a low speed there is a delay before the engine responds. *kb the consumer stated he experienced a significant abrupt downshift when slowing down from higher speeds and an abrupt upshift when accelerating from a slow speed. it felt as though the transmission could not decide what gear it should be in. the consumer was advised a computer patch was available for the problem, but it usually did not work and it could make the problem worse. *jb

 The lexus es300 has had a serious hesitation problem since delivery in march 2003. i have had it in for service several times before the accident complaining about this problem. on may 8th,2006, my wife was trying to make a left turn at an intersection and upon accelerating through the turn the car hesitated/lagged and was struck by an oncoming auto. after contacting lexus direct, they came out to test drive the auto. i was contacted several days later and was told that my lexus has no problem. since this problem still exists, i took the car back in for service on may 26th, 2006 and again was told that my car had already received a transmission computer update and their final words were vehicle is operating as designed at this time. this car still has the problem. *nm

 From the day i got the car the automatic transmission has been in trouble. the problem is the shift from 1st to 2nd. under light throttle there is free wheeling and engine run-up and it bumps into second. i know it will eventually fail. lexus has played with the computer control but can't correct this. they tell me this normal, but i know it is not normal for any non- lexus transmission.*ak

 There is a delay after sitting at a stop light and then at take off. the dealer could duplicate the problem and the manufacturer and dealer states that it is the new design. *ak the problem would also occur when making a left turn, merging into traffic, entrance ramps, intersections and parking spots. *sc *jb

 I have now sent my car in for service twice to lexus of orlando about unexpected surging of the vehicle and vehicle hesitation when the accelerator is pressed. this is an intermittent and dangerous problem, as i do not know when it will occur. when it does occur the upshift is harsh, the downshift delayed as if the transmission is confused about the driver's intention, and there is pronounced hesitation when the accelerator is pressed. this lack of responsiveness leaves both the vehicle and passengers exposed to accident and injury. on my first visit, i was told the vehicle computer would be reset, as the vehicle learns your driving style in the first 30 or so miles, and i must have driven the vehicle harshly. this so called reset did nothing to fix the problem; less than a week later, i narrowly escaped a crash after my car hesitated while crossing an intersection. i promptly returned the vehicle to the dealer for service. upon completion of the second service, which included a drive with the technician, lexus service now says these problems are inherent to the model and they can't fix them. in addition, i am aware that numerous owners frequently complain of hesitation and surging in 2002, 2003, and 2004 models and many complaints (over 100) of the same nature have been filed with the nhtsa. this statement is to issue notice that i am not satisfied, and the problem has not been fixed.*ak

 On two separate occasions, i have taken my 2003 lexus es300 in for service to repair a defective transmission. i have 23,511 miles on my vehicle and the transmission is shifting erratically and hesitating. it is causing unsafe driving conditions. lexus denies any responsibility to fix the problem.*ak

 Ongoing and worsening lack of accelleration predictability. car will hesitate especially when power is required (such as merging traffic, left turns, etc.) automatic ransmission sounds like it delays engaging when necessary.*ak

 Lexus es300 2003 - extremely dangerous situation when accelerating from 5-10 mph to full acceleration (passing/merging onto highway for example). transmission hesitates a very long time (1-2 seconds) before kicking in. dealer claims this is a known problem but nothing is being done about it. researching lexus forums indicates this is a wide spread problem for 2002, 2003 years at least. the hesitation is extremely unnerving in a high stress merging environment at least and potentially dangerous accident potential at worse.

 Car will not accelerate from stop at times. engines revs but transmission will not catch. several near accidents at stop signs and traffic lights. transmission shifts very rough and makes car steer erratically. car will be parked until repaired. lexus dealer states this is normal. *jb

 Ltr fm brett woody (tx) re dangerous defective transmission software problems in the 2002-2003 lexus es300, reply attn jan crow/ houston ofc. *ph consumer would apply more and more pressure to the brake pedal but vehicle wouldn't accelerated. *ph the transmission failed twice. lexus had given the consumer a new vehicle and it had similar problems. the vehicle almost had gotten the consumer into several accidents. on numerous occasions after the brake pedal was tapped, the vehicle would accelerate but the rpm's would fly up and the vehicle would barely move. in stop in go traffic the vehicle would surge forward. (this felt as if the transmission slipped then the surging occurred) there was an annoying rattle in the ceiling console. *sc

 There is a dangerous and unpredictable tendency for the vehicle engine/transmission combination to accelerate suddenly and unexpectedly. this is an intermittent problem which makes it especially unnerving. it is most noticeable at speeds below 40 mph, when first slowing, followed by acceleration. it appears to be exacerbate by uncertain transmission hunting for proper gear/engine speed combinations. the sudden acceleration causes a rapid and jerky throttle response to mild accelerator pedal input. i have taken the car to the dealer on at least two occasions for this issue. the first time, the dealer reprogrammed the transmission. the second time, the technician tested the vehicle and note no problem found. at current mileage of 32,000, the problem seems to be worsening. this is a dangerous condition that, if left undressed, is likely to be the cause of an accident, serious injury or much worse. *jb

 While driving and without warning, the transmission jerked, which caused the driver to pull off the highway. the driver had the vehicle towed to the dealer. *ak the vehicle jerked at acceleration, especially when going at slower speeds. the problem occurred with no warning and was intermittent which also displayed a sluggish delay. *sc *jb

 Transmission is unpredictable. sometimes it hesitates, sometimes it lurches. it shudders at times when shifting. i've had the car in to the dealer for 2 computer download fixes. the first lasted a day making the car seem like the demo i test drove. the car was returned and another fix by computer was done with no change to the querky, unsafe condition of this transmission. my wife was nearly broadsided in cross traffic pattern as the car hesitated as she attemped to turn onto a side street. i have had 4 similar situations. these problems are at speeds up to 40 mph. these problems do not seem to occur if you stomp on the accelerator from a stoped position. the genearal manager at the agency has driven the car around the block and experianced none of these problems. yet the servive dept. admits its not the way this car should operate and no further manufacturer update/correction is available. they say they are working on it. the manager says per toyota this is the normal way this car drives and they won't do anything to satisfy my complaint. these two statements are a contradiction. i've been advised by one of the technicians to use premium fuel because it would help the engine/transmission work better. i've done this since that conversation and the performance is still sub standard and in stop and go traffic still unpredictable and dangerous. *la

 Hesitation upon acceleration. i notice the vehicle lacks the ability to pick up speed from a slow down or dead stop. i feel this in 1st-3rd gears when accelerating from a deceleration speed or stop. this is very serious and is cause for safety concerns. i just bought this vehicle and i have another problem with a clicking, whining noise when turning into a parking spot or making slow turns.

 The transmission of the lexus 2003 es300 is subject to major hesitation, particularly in crowded intersections and with lack of acceleration. very noticeable when traveling about 27 mph, and then needing to move, there is major delay in the signal telling the engine, and transmission to work together, and move the car. this vehicle is new with about 1000 miles. it cannot make up its mind to upshift or downshift and this delay will mean a major crash someday. around 40 mph it wants to upshift to the 5th gear, and just below that hunts to go back to 4th. the mfg. says, as he did for the 2002 models, that a software fix is being prepared. they stated the problem from the 2002 was fixed. evidently that is not the case. they now tell me that a fix is coming year end. how many accidents will occur by then? dealer says that the car will learn from the driver, but that is not working, and hesitation from 0-5, from 27-45, etc. is very pronounced. if you floorboard it from slow speeds, its hesitation is great, and car almost dies. lexus says don't do that, but from car creation to now, car movement meant add more gas, not the reverse. my safety depends on it. *nlm

 The new 5 speed transmission on my '03 lexus seems a little strange. if i drive about 35 mph and then slow down to about 5 mph and than try to accelerate there is a hesitation. it's as if the transmission can not decide on what gear to go into. when it finally does there's a slight lurch forward. this situation is very dangerous when trying to pass another vehicle. *nlm

 When accelerating out of a slow turn(usually a u-turn) the car will delay approx 1 second before transmission engages. when slowing to stop but not completely stopping the transmission feels like it is slipping when accelerating. *jb

 Since my acquisiton of a 2003 lexus es-300, the vehicle has displayed very uneven shifting and hestitation as the transmission upshifts and downshifts, particularly at low speeds. in response to my complaint after 2,000 miles of driving, the dealer examined the problem and i was told that lexus had provided a solution in the forms of a re-flash for the on-board computer. this was performed, however, failed to improve the situation at all. when i complained a second time after 5,600 miles of operation, the dealer told me that nothing further could be done and referred me to the lexus national customer satisfaction line. after several calls i was told by a national representative that the vehicle was operating as designed and nothing could/would be done. in its present condition, the vehicle is both unpleasant to drive and unsafe since it hesitates before accelerating.
