CamryGeneral discussion forum for the Toyota Camry.
This is a discussion thread titled "2.4 acceleration delay", within the Camry forum, part of the Cars & Vans Forums category.
I'm dealing with the same issue on my wife's 07 4cyl Camry.. We've taken it to them 3 times so far with no luck in fixing it.. They applied the TSB to it back in January, but it's still hesitating like crazy.. I've got an appointment to bring it to them Monday, and the service mgr said that a couple of things came out recently that may fix the problem.. If they don't get it fixed this time, I think I'm going to push for them to buy it back under the lemon law.. It's just not safe trying to pull out and wondering if the car's going to respond or not..
This is a problem that needs attention, Here is my story. I must first say that I was a toyota salesman and sold these cars. with that said , I bought this camry mainly because of my discount. I noticed this delayed throttle response the first week I had this car ,"Yes the problem is a delay in the signal from the accelerator pedal to the throttle by way of the computer in their fly by wire system with memory not the transmision as others have said". I was told by the service dept. that it needed an update but they found out it had already had it and they reset the memory which did not help. Soooo they said toyota was aware of it and working on a fix. I got tired of the waiting so I called toyota and got a case manager to help get things done. After she called my the service dept they called me in to try to fix it again they could not and would not even try "NO ROAD TEST" and told me that they had a lot of camry owners listed to call when they got a fix. I told this to my case manager and then asked if she could tell me when and what there were working on to fix this, she talked with toyota's engineers and they told her that they were not working on a fix and did not plan on fixing it. Then she said that I should file for arbitration using the lemon law So what appears to going on is that they are telling the dealerships that a fix will be available and to tell camry owners that it is coming. I know this because when I worked at toyota, that is what the service writers ,service managers and mechanics really think. but in reality toyota is not planing on fixing this because they can not without spending a lot of money "MY OPINION." I have started the lemon law process by filling out the form located in the middle of your owners manual and I urge everybody to do the same soon, the whole process takes about 40 days, I will repost after my case is settled to let everybody know the outcome. I was told that in arbitration the arbitrator and toyota rep will be there and that you can take them on a test drive to show them what the problem is and I am very much looking forward to this because my car has this problem everyday and I consider it a dangerous situation in a variety of driving conditions and traffic as I found out last night in rainy conditions. One more thing, some of you think this is a transmission problem because of the down shifting, but it does this because when you are pushing the gas pedal down and the engine does not respond quick enough, the computer reacts to the pedal moving down enough to to trigger the downshift that is why you get that delay and sudden acceleration which can be really danderous on wet roads if you don't have traction control, as I found out last night trying to accelerate out of a turn while it was raining. Please be careful this is a safety issue not just an annoyance. There maybe some of you out there that may not agree with my opinion of the the downshifting and delayed acceleration explanation but in any case these camry's do not run like they should and need to be recalled.
well i just got my 07' camry {ce 4cyl.} delayed acceleration fixed at the dealer.. i was prewarned when i got there that it might not make a difference after the mechanics were done..but i had told her that i have 20 pages printed out from this website that says that there should be no escuse why it shouldnt get, taken care of this time. With that known and after driving it the 15 miles the mechanic had told me to do, so the computer can program itself on how i drive , i have to say that the delay is no longer there. It definetly worked on my car .. and any dealer shouldnt bul**** you and say it cant be fixed..its a known "TSB" ...and its a simple fix with a reprogram of the cars computer. ....As other posts had said ..the mechanic had explained this happens because the gas pedal is no longer hooked up to a cable now. and its all done with sensors on the pedal and then it sends it to another sensor to open the throttle.. they needed to just change the delay from seconds to miliseconds..and its definetly made a huge difference..and got rid of the safety issue of accelerating when getting onto on-ramps, etc. any questions just ask...i also upgraded my stereo system in car , so anyone needs info on that let me know.
I got rid of my 04 Lexus RX300 over that crap. I see Toyota still hasn't fixed that issue. The real problem is they can't figure out how to program their transmission and it's a dangerous problem. I have heard of Lexus owners being rear ended due to this problem. I finally got tired of installing TSB after TSB with the promise it would fix the issue.

I got a call from the service manager after he got a call from toyota after they got my lemon law notice. anyway he told me that they have done the tsb and that was all they could do, but then he told me he agrees that it is a problem that toyota does not have a fix for. He said he has a lot of owners with this problem that he cannot fix and he was on my side about getting toyota to do something about it. as of the other day he had 2 other people who had enough stalling and he was adding my case to them to send to s.e.toyota to let them know that they need to address this soon. He knows that the dealerships are taking the blame for toyota's mistake and he wants some action. as for the poster who said it is fixed,I would wait awhile before you declare all clear because I know the head mechanic at the dealership who owns one of these cars and he cannot even get his to work right after a year of trying. my arbritration meeting is in 2 weeks at the meeting will be a toyota rep, the arbritrator, the service manager and myself, this will be an attempt to work out a solution so I will post when we get that done and let people know the results.
Well, add me to the list. I rarely drive my wife's car because she hates driving the Sequoia. But when I drove the Camry last week, I thought I was going to get rear ended just changing lanes! Then I finally noticed that everytime I turned a corner, it always hesitated.
So, I get home and tell the wife. She says, and I quote "Oh yeah, I noticed, but I just compensate for it and am used to it now." What the (*&^(&*^?
Going to the dealer early next week. I now have an excuse to drive her car, and I will post results.
Since my wife's Camry is still having this issue and 5 trips for servicing haven't solved the problem, I called the dealership General Manager and talked to him about it.. He raised the issue to his Service Manager, who called me back later on to discuss the problem.. We're supposed to bring the car to them sometime soon (when it's convenient for us) and leave it with them for their head technician to look at.. So we'll see..
I think what is really causing the problem is the fact that the drive-by-wire system remembers your driving habits.. So if you're an easygoing driver, the system has problems when you try to accelerate more than it's used to you doing.. There needs to be a way to have the system not remember your driving habits and just have it respond to what you tell it to do.. I shouldn't have to drive like a bat outta #3|| for however long it takes for it to learn my habits for the car to respond normally when I just touch the gas..

If we run a search – we will find thousands of discussions involving major brands. Some examples are here:
this is to reply to some private messages but I think it will help everyone,well my first attempt was denied but I learned alot about the process so this might help others on how to do better. it was denied mainly because my car did not do it when the arbritrator was in the car and then we drove another rental car with the same milage and it was just as bad if not worse than mine, so he ruled that there was no signifacant difference. But this is what I learned for when it starts doing it again, I would take it to a certified mechanic when it is at it's worse and get a written report of the problem also there is a lawyer here in florida that will take a case after 3 try's to fix and no results maybe there's one in your state check the web, that would be the best chance to get refund. the arbritation outcome does not keep me from doing that. also about 2 weeks before my hearing I started doing alot of quick accelerations at different speeds to try and get ready to give examples of the situations where it would hesitate and guess what after 20-30 times doing it the car started working alot better so when I test drove at arbritation it did not hesitate hardly at all, but after reading the tsb that is one of the things they are suppose to do when they do the tsb. Today I decided to try premium gas and now it realy runs good so I don't know what to , I will see if it still runs this good in the winter time, because that is when it was hesitating the worse, if it does run worse I am going to do the mechanic and lawyer route. the funny thing about this is that the overall general service manager at the dealership agrees that there is a problem and he has made a complaint to toyota about it too because he has a bunch of people with this problem. this may be a case of the dealerships not doing the tsb properly or a engineering flaw and someday they will have to do a recall when someone has an accident and somebody gets killed becuse of this problem " my opinion ", that was one of my reasons for doing this just in case someone in my family pulls out in front of somebody and causes an accident I will have a record of this complaint. any way if you have brought your car in 3 times or more and they cannot fix it it is time to talk to lawyer I did and he told he would take the case if they tried 3 times here in fl, but the problem was my dealership would not even try and turned me away, the lawyer said to take it to other dealerships when this problem occures to get to 3, so I might have to wait till winter. bottom line is you should talk to a lawyer and a nada mechanic to get it documented. I hope this helps because I know there is something wrong with these cars and it 's just going to take more people using the lemon law to get results.
My 07 Camry SE was experiencing the same acceleration problem. I took the car in last Friday and gave the service associate the TSB. The mechanic applied the update and test drove the car as stated on the TSB. The TSB fixed the problem. I will say that I expected a more noticeable improvement but any improvement is better than no improvement .

Thanks Toyota!
It's strange.. My wife took her car in for another inspection a couple weeks ago, and one of the service technicians rode with her.. He didn't reset the computer that I know of, but he had her accelerate in the manner described by the TSB.. I had assumed the dealer performed the test drive properly when the computer was reset initially.. The car hasn't hesitated since then.. She still doesn't care for it and wants a 4Runner now I think, but at least the car seems to be working fine now..
Not sure if there is more than one fix for this TSB but it had nothing to do with resetting the computer i dont think.
I got my local Toyota to apply the TSB since i provided them the code for it.
On the Invoice sheet it says "Engine Re-calibration applied"
Hope this helps for those who haven't got their TSB's fixed.
I felt a big difference the very second i got my car back. I tried accelerating from rest and it actually changed gear properly while it was accelerating.. NOT the previous feeling (before the TSB fix) where it hesitated to accelerate or it felt like this car had no power at all.
