When I'm driving about 35mph or higher...if all of a sudden I push the Accelerator Pedal to get a needed sudden increase in speed (Like in a lane merge on the freeway), the car hesitates and takes several attempts until it does.
  
Took the car to dealer (jersey city).
They Recaliberated ECU ENGINE AND TRANSMISSION (PER TSB#EG056-06).
  
Then was advised the car would be sluggish for about 10 to 15 miles then it would be ok.
Also, the mechanic said "your car should be much better now but there will always be hesitation....it's normal".
  
Drove the car 25 miles to confirm that hesitation when pushing the accelarotor while on 35 or highr speeds doesnt increase the car's speed.
  
Called dealer again and they were more than eager to help.....will see what happens when they check the car next week.
  
Also! I test drove a camry LE at another dealer and found out the car got the same problem.
  
So it looks like a defect in all 2007 CAMRY LE.
  
Needless to say, this condition in the wrong situation can result in severe injuries and even death!
  
I think at this point it may be too early to file a complaint re this defect to NHTSA (http://www-odi.nhtsa.dot.gov/ivoq/).
  
Must say service dept of Toyota at jersey city is very responsive.
  
Please share your experience.
  
Thank you

Thanks, and i beleive "That's the idea." We need to help each other, although i did not buy my camry yet; the only reason that is holding me is the "transmission issues that you see people speaking about on Yahoo, MSN, AOL, etc. just check their web sites. However, i am willing to wait a couple of months to see is that hanges. My point is the following: although i admit tha the new camry looks great/ and has all the new stuff (ebd, ba, 4 discs, mp3, more airbags, etc, etc) you can get a decent deal for a honda accord today for $1000 below invoice) and a better financing option. Now the only thing that has me i between them is the shape of the camry; but as far as i know, the honda accord continues to be the best car in Aerica. those are the only cars that you will see running with more than 300000 miles, with no major mechanical probles, has the best re-sale value, and any dealer will pay just as much for your car as anyone off the street. Like i said it is just about the body.

I just found this message board. I have a V-6 SE that had the transmission replaced 2800 miles, this was back in July 06', and got the car back and experienced a leaking noise like my window was open. I took it back again where they fixed that problem. Now with my new transmission I have 13,000 miles I was still experiencing shifting and hesitation problems so at my routine oil change at the dealership I told him about the transmission problems I was still experiencing and asked if these were new transmissions in the 07' where the assistant service manager said that they were having all sorts of problems with the 07' and that they were trying to fix the problem before they sold them. Well I get my car back after the routine fix to experience a noisy car at 70 MPH so I call my salesman that I bought the car from and told him that I have had it with this car and got a return call from the customer service manager telling me to test drive it with the head technician. I did this yesterday to find out that someone was installing I believe he said a clucth part upside down and this has caused damage to the transmission. He also told me that the transmission is computer operated and they have had to make adjustments and they came out with the 4 cylinder replacement chip but he wasn't sure if they have come out with the V-6 computer chip. Hopefully Toyota will get this corrected.

Since you have private email I am sending this public. If you would have taken the time to read througn the posts here you would find that everyone has already shared their thoughts and their is NO cure for this problem at present. Toyota has half heartedly at best tried to solve this problem but for the most part denies it. Only way I see of this problem being solved is through mass lemon law compainsts or a class action suit which will get the media's noise into things and we all know what the media will do. They will have no choice but to work on the problem big time until it's fixed.

Since this EXACT problem, 1-2 second downshift delay upon re-application of pressure to the gas pedal, first began to be reported with the 2002 Camry (and 04 RX series) I rather doubt it will be fixed anytime soon.
 
Ford has just announced that the new Ford Edge has a variable displacement ATF pump which I strongly suspect is being adopted to solve this very same problem as is being reported for many of their FWD vehicles.
 
Knowing how the "standard" fixed volume ATF pump is constructed within most automatic transmissions it is hard for me to imagine how it might be easily converted to a variable displacement pump.
 
Were it me I would look into adding a small accummulater pressure storage tank much like the one used in the ABS pumpmotor assembly.
 
Adopting a variable ATF pump would very likely mean a complete and total redesign of the transaxles and that might be an explanation for why Toyota has not yet come up with a satisfactory fix.

How about they do away with the electronic gas pedal and go back to a wired version. Do you think this may help?

i think the problem with doing that is that now the throttle valve position is under the control of the ECU with the accelerator pedal being one input; DBW is infrastructure for some safety stuff like VSC where you might want to intentionally de-rate engine power even though the accelerator is being pressed more.
 
with the linkage being mechanical, the throttle is going to open and close with the accelerator pedal. and if the gas doesn't increase when the pedal is pressed, and the throttle is opened, then you can go too lean and stall which is a no-no and safety problem in and of itself.
 
isn't DBW fun fun fun?

I wonder if the Hesitation problem puts the CAMRY LE in the LEMON category
 
Aside from class action suits...I thinke if all of us make it a point to RATE the CAMRY LE in as many places as possible...this might help.
 
By the way, any suggestions as sites where we can rate
the camry to reflect this serious problem?

Well, yes and no.
 
First, the only Toyota I own is a Prius.
 
But I do have a 2001 AWD RX300 which exhibits the earlier symptoms resulting from the revised shift pattern/schedule adopted late in the last century as a safety measure. Seemingly on all Toyota, Lexus, Ford and VW FWD vehicles with automatic transaxles. At least those are the marques wherein complaints of 1-2 second throttle lag or downshift downshift delay/hesitation problems can be most easily found.
 
My solid suspecion is that sometime late in the late century, say 1995, the automotive insurance industry approached the automotive manufacturing industry with the news that statistically FWD and front torque biased AWD vehicles were proving to be dramatically more hazardous(***) in foul weather conditions than their RWD and rear torque biased AWD counterparts.
 
The obvious message being: "either fix what's wrong or we will start charging a premium to insure FWD and..., vehicles."
 
Another obvious point along this line is like the over-confidence drivers of 4WD/4X4's get in foul weather so do many FWD owners due to the extra traction provided by the engine weight being over the driven wheels/tires.
 
But that wasn't the major issue.
 
Engine compression braking on a FWD vehicle can have a really adverse affect on vehicular control on a slippery roadbed surface. Even more to the point the anti-lock braking system can be made non-functional due to engine compression braking.
 
So nowadays almost all FWD and front biased AWD vehicles with automatic transaxles will UPSHIFT upon a FULL lift-throttle event. That leaves you in coastdown mode in to high of a gear ratio should you suddenly have need for quick acceleration.
 
Because the engine is now at idle and with the trnasaxle having just completed an upshift there is now insufficient ATF pressure/flow to complete the required downshift quickly.
 
So the manufacturers have chosen to use DBW, e-throttles, to delay the onset of engine torque developement until the downshift can be completed.
 
*** Ford Motor Company has just been awarded a patent for two techniques which appear to directly address this issue. The first of these involves substantially reducing the level of regenerative braking on a hybrid vehicle when the OAT declines close to or below freezing. The second involves disabling regenerative braking the instant the anti-lock braking system activates so as not to interfere with ABS activity.
 
The only vehicles in production to which Ford could currently apply this patent are both FWD or front torque biased AWD.
