| S10 appropriate handling re toyota vehicle sudden acceleration problem, owner of a 2006 toyota avalon experienced acceleration problem. *tgw immediately after purchasing the vehicle, the consumer noticed a problem in accelerating, decelerating and shifting gears in the transmission. since the vehicle was still under warranty, he took the vehicle back to the dealer a few weeks later. the dealer informed the consumer there was no major problem and that a minor adjustment was made to the shifting points in the transmission. the vehicle functioned fine for a while, but then the same problems quickly resurfaced. a toyota representative stated the problem was not a defect; rather it was the way the vehicle was intended to handle due to its drive-by-wire system. the representative went on to say the drive-by-wire system did not have a traditional rod that connected the pedal to the engine; rather, the pedal went to an electronic system that sensed the intended acceleration and causes the engine to accelerate as directed by the driver. the consumer was told the hesitation he complained of was normal as the system was determining how much to accelerate. the consumer did not believe the sudden acceleration was due to a sticking pedal; rather a problem within the electronic transmission control module, throttle or onboard computer.*jb | |||

| 2006 toyota avalon gas pedal does not provide power until depressed over 50 percent travel then it suddenly provides power representative of half throttle. the check engine light flashes on and off when it does deliver power under this condition. on rare occasions when moving from stopped position the car accelerator is overly sensitive and acts like i just stomped onthe gas pedal and not the slow movement i gave te gas pedal to make a slow movement of the car. i have gotten used to the way it drives and it has been this way for the past 10 months. today the gas pedal has very little response to throttle response. i cannot drive it this way and having car towed to dealer for service. some days after driving over 30 minutes the car acts normally with exception of check engine light illuminated. *cn | |||

| I was traveling on the ny i-87 in my 2006 toyota avalon for approximately 30 minutes when the check engine light illuminated. within a minute or so, the check oil light started blinking slowly at first, then after about 30 seconds it was on continuously. by this time i had pulled off into a gas station. as i was pulling into the station the engine was making a loud clicking noise. after it was parked, i checked the dipstick and there was no oil remaining in the engine. the underside of the car, including inside of wheels and brakes was completely coated with oil as well as the back of the trunk. presumably from the spray underneath while traveling @ 65-70mph. i then purchased 3 quarts of oil, put it in the engine and it drained onto the ground. the mechanic stated there is a pin hole in the rubber section of the oil line. the use of a rubber hose for a pressurized flammable liquid system in this location is absolutely reckless. at a minimum, it should be some sort of armored or shielded hose. i'm amazed the car didn't start on fire from being doused with five quarts of oil leaking from the ruptured hose. the service person at the dealership indicated this is a common problem with 2006 avalons and he couldn't understand why there hasn't been a recall issued. the engine repairs caused by this defect will cost me up to $5000. today i found at least a 1000 complaints regarding this same issue on carcomplaints.com and aboutautomobile.com. i would hate to see a death result in this issue caused by fire due to hot oil. *tr | |||

| I think i experienced a surge in my 2006 toyota avalon. i was not sure but people observing that did not stay and wait for police said my car raced forward after stoped at a light. i ended up steerring to the right and hit a tree rather than the car ahead or pedestrians. when the police and tow truck arrived they indicated that my airbag should have gone off, but it did not. | |||

| I have a 2006 toyota avalon. i took it in a few weeks ago to have the accelerator recall problem fixed. today (3/14), i was traveling thru a shopping center parking lot at 10 to 12 mph. as i touched the brake, the car started to accelerate, grinding thru the brakes. i pushed it into neutral and jammed the brake. there was a very loud thunk and the car stopped and ceased trying to accelerate. *tr | |||

| I'm an owner of a 2006 toyota avalon and i'm curious if the electronic transmission has been investigated as a cause of the accelerator issue? i purchased this car as a new car and within 2 weeks i returned o the dealer to have the transmission checked. at this point it lagged when downshifting or seemed to be continuously searching for the appropriate gear. i was told that he computer had to learn our driving style and the issue would go away. it has never gone away, and it seems to have gotten worse over time. i have 60,000 miles on this car. *tr | |||

| The first week i owned the car i noticed a hesitation in the accelerator followed by a lurching forward. took it to dealer who said it was caused by the drive by wire system and would adjust to my driving in time. no adjustment occurred. i continued to make complaints to no avail until i threatened write to nhtsa. they then said wait, don't do that. we'll talk to the service manager to see if he has a fix. within 30 minutes they had recalibrated the engine control module/ecm (sae term: powertrain control module/pcm). warranty information was: op code eg7023; description recalibrate emc (pcm); time 0.9; ofp 89661-#####; t1 26; t2 99. the results were good although i sometimes still feel almost undetectable small surges when i am driving as if i am not really controlling the speed with the accelerator. by the way, i had reported this twice before and when i read through all of the 2006 avalon reports mine was not there. are the reports deleted after a period of time? *tr | |||

| When slowing my 2006 avalon for turn, speed bump, etc. and then accelerating there is often a lag in the transmission engaging and when it does the car lurches. i have complained many times to 2 different dealers about this since the car was new. after a year or so 1 dealer said that toyota had issued an adjustment procedure which they performed. the problem went away for a while but has returned. in light of the recent recalls and stories about possible electronic problems with these cars i wanted to add my story to the list. i consider this a serious safety issue since the lag in transmission engagement could cause an accident when making a left turn, especially if it worsens. further, the only way i know about this latest recall is through the news - toyota has not notified me directly. this makes the third recall on this car - floor mats, vvt-i oil hose and now accelerator! needles to say - i am not happy with my purchase and will seriously try to convince my wife to take our business elsewhere in the future! *cn *tr | |||

| This is just to pass along to you that i too have experienced that odd sensation of momentary acceleration while driving, but while letting off the accel pedal. on the handful of occassions when it has taken place, i believe i was always driving in heavy stop-and-go freeway traffic. almost from the first day i leased the car, i have complained to friends that i thought my electonically-controlled transmission was too smart--that it thought it knew better how to drive the car than i did. i have a feather touch in my driving style, and i have not liked how the transmission is constantly trying to figure out if it wants to be shifting up or down in heavy traffic. now, with the recent media coverage, i am wondering if the issue is broader and could be part of the unintended acceleration issue? *cn | |||

| I have a 2006 toyota avalon xls and i had problems with sudden acceleration when stopped at a red light with my foot lightly on the break pedal, the engine is running, and the car is in gear (drive). all at once, the car would accelerate forward really fast but stop when i push hard on the break pedal. i was thinking that maybe my foot was slipping from the break and onto the accelerator pedal without me noticing it, however, in light of the recent publicity about the gas pedal problems with toyotas, i am thinking that maybe my foot was not slipping and this piece of information may help in the fault isolation process. it doesn't happen all the time, i would say about once every few months. my reaction on the break pedal is fast and it does stop the car. *tw | |||

| I took my 2006 avalon in to nalley toyota for an oil line recall. i asked them if they could also look into the floor mat recall for me. they told me no decision had yet been made on the floor mat issue but went ahead with the oil line recall. i picked my car up that afternoon, drove 15 minutes to my mother's apartment. while slowly guiding my way into a parking place, my car accelerated violently propelling itself up over a curb and through a wooden fence, landing with my back tires on the front curb of the parking place. my braking had no effect and upon landing on the downside of the slope, my engine died. i called toyota immediately asking what they could have done to cause this to happen since my car had never had this happen before in the 4 years i had it, and yet happened 15 minutes after they had worked on it. they said nothing was done that could have caused this. we complained to the area toyota rep and an inspector came and look at the car at the nalley repair shop we had it towed to. toyota says my car checks out fine and any problem was caused by the floor mats /driver. the serviceman did not advise me to remove the floor mats that were in place when they were working on the car. they released it to me with the floor mats in place. furthermore, i contend that the first thing i check after the sudden acceleration was the location of the floor mat,which was flat against the floor. *tr | |||

| The transmission hesitates, jumps, and bucks and acceleration is very uneven. when accelerating from 0 mph (i.e. at a red light), the car hesitates, and then at approx. 20 mph, while keeping the gas pedal steady, the rpm's rev up, and the car accelerates wildly. when the transmission shifts at around 20 mph, it feels like it shifts into a gear above what it should be. the car always feels like it is in the wrong gear. this causes problems when accelerating and braking and has caused numerous close calls. *tr the consumer took the vehicle to the dealer, and they made a minor adjustment to the shifting points in the transmission. updated 02/17/10. | |||

| Avalon limited 3.2l v6 * automatic transmission * 72,900 miles well, this is my 3rd toyota, the car was running fine up until thursday night when i started the car i heard a cranky fan like noise, i did not know what it was after i drove shopping and came back after 2-3 miles and parked the car on my driveway in the dark. next morning when i pulled my car out of the driveway the noise continued and i saw a pool of engine oil all over, i called the dealer immediately and surprisingly they offered to repair the car the same day (same day appointments-never happened before even for just oil changes) after taking a look they said the oil line needs to be fixed and cost would be $450 for a half days work. i called back the evening and was told now they called toyota as they don't know what was wrong but have not heard from toyota so i wont get my car up until after labor day weekend- (had to get a rental for a week) next week, they told be the gear shaft cracked and gaskets need replacement and a 16 hrs job and would cost approx $6000 to repair but toyota will cover 50% even though i am out of 60,000 miles warranty. i did some research and found this is a manufacturer defect. i walked in to dealer to see my car and the mechanic showed me the broken part and told me toyota has since redesigned this part so it does not break and cause sudden oil leaks- once the new part is replaced i should not expect more similar problems- i am keeping my fingers crossed. i called toyota and they made a note of my problem but said i have to get the number of the toyota regional manager from the dealer who said he cannot let me talk directly due to business relationship with him. i told them its not fair for the customers to pay for the manufacturing faults of toyota. finally the hidden toyota regional manager offered to settle for paying 2/3 rd for my car's repair. i am concerned about others driving the avalon and a big cover-up by toyota. *tr | |||

| The transmission acts erratically at low speeds. if i am rolling through a stop sign or just in traffics at 5-10 mph the transmission will hunt for a gear. sometimes it is a hesitation and sometimes it jerks into gear, depends on how much trottle you apply. if i am stop turn right on red, have plenty of time to make a turn before an approaching car arrives, if the transmission is hunting for a gear, i have no control of the car. it might be only for 1 or 2 seconds, but it is dangerous. repeated service trips, service manangers and even district manager has failed to get anyones' attention. check out this web site, here are 44 people with similar problems:http://fourwheeldrift.wordpress.com/2007/01/16/toyota-avalon-transmission-problems-expose-toyotas-problem-reporting-problems/ *tr | |||

| I bought a 2006 toyota avalon in sept. '06. there is a serious problem with the transmission. at slow speeds the transmission slips. if i am slowing almost to a stop and then starting up again the transmission does not engage, the engine revs up, and then the car lurches forward as the transmission finally engages. we have almost been rear ended when another car is following close and thinks that i am going to move forward but can't because the transmission does not engage. i have almost had an accident because the car lurches forward after the trans slips. i also have to wait for a very large gap in traffic if i'm crossing a lane to make a left turn as i never know if the transmission will slip leaving me in the on-coming lane of traffic. we have had this lurching and slipping incident approximately 60% of the time. on two occasions when reaching speeds that would be shifting from 2nd to 3rd a very loud banging noise and lurching occurred. unfortunately, on two visits to the dealer i was not able to recreate the problem. *jb | |||

| When entering traffic from the on ramp and with plenty of time under normal conditions my toyota avalon, upon acceleration the engine actually cut out i mean with a serious hesitation that i could not respond to in time. the auto quickly approaching my rear veered into the next lane causing the third car to run off on the shoulder of the road. this is indeed a highly safety problem. i escaped without a scratch to myself or car. this has happened many times before but not to this extent. i took my car back to thompsons toyota in placerville ca 3 times for the same problem and each time they tell me they can't find anything wrong with the acceleration. i have about 10,000 miles on the car now but the problem surfaced less than a week after i bought it. what are my options i need the car and i must drive this safety affected product. the car is ok after you get to 60 mph. on acceleration from a stop position a 4 cyl. corolla and honda can perform better, in fact i have a tacoma toyota 4 cyl 1999 with 100,000 mile that also accelerates better than my avalon. *jb | |||

| I was driving slowly around a rotary, and took my foot off accelerator to drift a bit to allow a preceding car to enter. when i pressed the gas pedal gently, there was a sudden violent kick which frightened both me and my wife. (i believe the transmission had shifted in low, but it was as if we had been hit in the rear with a large slapping hand!) i had to react quickly to avoid being driven into the car ahead by this sudden small burst of speed. an accident could easily have otherwise taken place. the transmission has always been erratic at times since we purchased the car, but this was the worst thing that has happened. i have had the latest computer upgrade on this problem installed, and it was within 1 day after that this took place. i had read all of the nhtsa safety reports on this car, and there have been many similar. in my mind there is a serious safety problem which needs addressing. (a similar but much less violent series of incidents have occurred when in cruise control going somewhat uphill, when it downshifts and the car speeds up noticeably and in some cases so much so that i have to take it out of cruise for a bit) such unpredictability makes both my wife and i feel unsafe in this car at those times. *jb | |||

| 2006 toyota avalon. at low speeds, especially after slowing, the transmission acts as if it were in neutral, and severely hesitates, when an attempt is made to accelerate. dealer says it's normal. there are years of complaints all over the web. i can't believe that some have not been rear-ended or struck when attempting to accelerate into traffic from a highway entrance ramp. toyota should be forced to redo the programming of the responsible computer chip or replace the chip with one that has a faster clock speed. they should also be held legally responsible for all incidents. the date below is for the latest of near daily, usually minor failures like slowing to turn a corner. | |||

| I own a 2006 avalon ltd. upon entering the on-ramp to route 23 in wayne, nj, i depressed the brake to slow the car. after confirming there was room to merge, i applied the gas and attempted to merge. i noticed and heard the tachometer surge but the transmission did not engage. i lost my opportunity to merge and had to quickly apply the brakes. by then, the ramp lane had ended and i had to turn onto the shoulder to avoid hitting an oncoming car. i brought the vehicle to to the dealer who examined the car and stated that this was/is normal operation when compared to other cars of this type. i opened a complaint file with toyota ((#20060719xxx...last 3 numbers left out intentionally). the transmission on this car continues to exhibit erratic behavior (transmission hesitation) under these same conditions (braking followed by acceleration). this situation significantly hinders my ability to safely operate my vehicle while merging into traffic. *jb | |||

| I was on my way to the dealer for an oil change and to have our new (picked-up 26 jan 06) toyota avalon looked over as it had 3,500 miles. we live in the ozarks and of course it is very hilly. i normally use the manual mode on the automatic transmission to slow the car down as to descend the hills leading into and out of our sub-division. however, on 23 jun i just left it in the regular automatic mode and used the brakes. when i saw there was no on-coming traffic, i stepped on the accelerator to go---the rpm's jumped to over 3,000 and then the car lurched forward. thank goodness there was no on-coming traffic--i can only imagine what might have happened. i asked the dealer to check this occurrence out--they couldn't duplicate. since the first incident i've had the same thing happen on 4 separate occasions--always when left in the automatic mode and after you've slowed down and then press the accelerator to go. i've read on the www.edmunds.com website about others who've experienced the same thing. there is definitely something wrong and before a serious accident occurs toyota needs to fix the auto transmission problem. *jb | |||

| Re: toyota 2006 avalon i recently bought a toyota avalon. it now has 3800 miles on it. in the second week after the purchase, i was driving on a ramp to enter a limited access high way. speed was about 50 mph as i blended in with the flow of traffic. the lane i was in started to slow down and the lane to my left had an open space. i pressed on the accelerator to gain speed and turned the steering wheel toward the left lane. the car, instead of accelerating, appeared to go into neutral, the tachometer reached almost 7000 rpm, then the transmission shifted into the passing gear and leaped forward. i almost hit the rear end of the car in front of me, but since my car had slowed down a little i was able to steer around and get into the left lane. i have gone into this detailed explanation to demonstrate the danger, and potential terrible accident at 50mph that the | |||

| Dt*: the contact stated while depressing the accelerator pedal, the transmission momentarily hesitates before properly selecting the correct gear to engage. this occurred at speeds of 5 mph and above. the vehicle was taken to the dealer several times for inspection. the dealer determined the electronic transmission software needed replaced. however, the manufacturer did not have aftermarket software available and no repairs were made. updated 03/17/06. *jb | |||

| 2006 toyota avalon. at low speeds, especially after slowing, the transmission acts as if it were in neutral, and severely hesitates, when an attempt is made to accelerate. dealer says it's normal. there are years of complaints all over the web. i can't believe that some have not been rear-ended or struck when attempting to accelerate into traffic from a highway entrance ramp. toyota should be forced to redo the programming of the responsible computer chip or replace the chip with one that has a faster clock speed. they should also be held legally responsible for all incidents. the date below is for the latest of near daily, usually minor failures like slowing to turn a corner. | |||

| Purchased a certified, used 2006 toyota avalon touring model on july 15, 2006. within the first week of ownership, i noticed a serious hesitation in the transmission, especially at speeds below 10 mph. i took the vehicle to koons toyota dealership on july 8, 2006 and had the service department shop foreman, drive the vehicle. he confirmed that the transmission was indeed hesitating and that this was a problem for 2004-2006 toyota siennas, avalons and camrys that share the same 5-speed automatic transmission. chris told me that the computer that selects the appropriate gear based on various criteria analyzed by the system is too slow in processing this information, which in turn causes the hesitation and rpm surge before a gear is engaged. i lodged a complaint with toyota today (case number 200608090063), and was told that the corporate line is that the transmission is behaving as was intended. the dealer told me this issue can be fixed by a reprogramming of the computer or replacing the chip with a faster version. obviously, this is a terribly dangerous situation that toyota needs to address. *nm | |||

| The problem seems related to the powertrain control module problem never occurs when the vehicle is cold or from a stopped position. problem is not consistent on average occurring once a day description of problem: in parking lot or after lot of low speed driving form traffic problem occurs?.. accelerate the rpms race on the tach and the speedometer is out of sink there is a delayed response a shudder, shift timing feels off kilter, erratic hunting, then a harsh forward this may be a one time event or several in succession and then returns to normal shifting pattern 2- cruising 30 mph problem occurred gave it some gas... tach shot to 4k delayed forward engaging then the car drove itself for 1/4 mile without me touching the accelerator 2006 toyota avalon. *tr | |||
