Intermittently, the vehicle will not respond to the throttle. The problem happens frequently, particularly when I brake and decelerate from above 30mph, then make a turn, such as exiting an off ramp, at about 5-20 mph, I press the accelerator to accelerate out of the turn, and the throttle does not respond for about 3 to 15 seconds. I consider this a serious safety issue where I cannot depend on the vehicle responding to the throttle allowing me to control the vehicle. This problem happens under other circumstances, and is completely unpredictable, but the above scenario is the most consistent. I took the vehicle to Toyota for this issue for the second time and was told: '..that is the way it is..' and "..this is how the fly-by-wire system works in the Camry.." by the service tech of power Toyota irvine on Tuesday Apr 29. He acknowledged that it is a safety issue and encouraged me to speak with the tech robert who knows how to work around the issue by manipulating the throttle and recommended that I complain directly to Toyota. He also mentioned that if I bug Toyota, they will be motivated to '.. fix the software, put a new computer in it, or take care of you some other way..'

After slowing to make a right or left turn, the accelerator "sticks" preventing/slowing acceleration in order to complete the turn out of the intersection and clear of oncoming traffic. Judging from internet sites through google, this is a problem that Toyota dealerships (mine included) are aware of, but do not want to do anything about.

My 2007 Toyota Camry hesitates when you first press on the gas. It has happened as long as 3 seconds. From a stopped position, pulling out on to a hwy. And going left, my car got me out on to the hwy. But then hesitated. I was still pressing on the gas heavily, but my car was not going! I would estimate about 3 seconds. I had an oncoming car traveling toward me and I was stopped in his lane unable to do anything. This hesitation happens frequently. I would say this happens several times everytime I drive my car. Toyota service dept. Says he has had several complaints regarding this issue and this year and make. He knew what I was talking about as soon as I made the call to him regarding the problem. He said that it is a problem with the main computer in the car. I took it in and they had to preform an "ECU update' which he said basically is resetting the computer. Sounds easy, but it took them 2hrs to complete. I am afraid someone is going to be killed due to this "ECU" problem! I could have been!!!

The contact stated that within ten key turns, the vehicle reprogrammed itself and he must disconnect the battery to reprogram it to its original setting. The failure remains uncorrected. The VIN was unknown. The failure mileage was 200 and current mileage was 10,000. Updated 02-12-08 the dealer stated replaced instrument panel assembly, A/C vent closest to steering wheel is loose, and hesitation between first and 2nd gear. Updated 02/12/08

Camry 2007 stalls when trying to accelerate.

- Charlotte, NC, USA

On several occasions, while attempting to accelerate from a stop, the engine hesitated severely. On more than one occasion attempts to cross at a crossroads or enter a freeway with plenty of time before traffic arrived resulted in several near misses with other cars. The failure of the vehicle to accelerate properly could cause an accident to occur. We have taken the vehicle to greenville Toyota in greenville nc, and they said it was a chip in the computer and that they were aware of the problem but were unable to do anything about it. Greenville Toyota representatives advised it was a manufacturer's issue.

I purchased a new 2007 Toyota Camry in June 2006. After returning the car to the dealership several times because of the sluggish acceleration from a stop was consistent and the passing gear downshift felt delayed as if there was a communication lag between the tcm and actual switching of the shift solenoids at speeds less than 50 mph. The cruise control will not set speed. On steeper grades and on the interstate the down shifts are very frequent and at times very dramatic. When cresting a steep hill the transmission down shifts at the crest and takes 2 or 3 seconds to release the throttle, picking up anywhere from 10 to 15 mph and I have to break suddenly in order to slow the car down. I was told by Toyota representative that a technical service bulletin came out in September of 2006 for an ECM calibration enhancement to shifting performance and smoothness and this new computer software had to be downloaded in the car and this would recalibrate ECM (PCM) engine & transmission. The catcher to this is that the customer has to request this download before the dealership will follow through. If you don't know about the bulletin how can an average customer request this? the download was performed on this car but didn't help any. The dealership took the car back and I was given a new one in Dec. 2006. Same thing with this one. I have been through national center for dispute settlement with an appointed arbitrator who had the car inspected by an ase independent inspector. He agreed with the above but in conclusion stated that Toyota should "diagnose and repair as necessary". I feel that this is a no win situation for the consumer and Toyota knows all about the problems but just doesn't know how to correct them. Because of the lack of safety the "lemon law" should be put into effect and these cars recalled. Toyota is not going to take responsibility unless forced. This is my first and last Toyota vehicle.

Throttle response delay in 2007 Toyota Camry (4 cyl. Auto) Camry - bought new 4/06 from Toyota of nashua (nh). Defect is a delay of 1 1/2 seconds in throttle response. Delay was most noticeable at normal urban traffic speeds of 35 to 45 mph. A light increase in throttle at constant highway speeds in the 35 to 45 mph range resulted in the engine 1) usually not remaining in high gear 2) having no response for 1 1/2 seconds, and 3) then roughly down-shifting, as if the driver had called for strong acceleration. The car's speed "sagged", and then the car's engine oversped. The driver then had to decrease throttle to prevent overspeed in traffic. Pulling out into traffic becomes unpredictable and dangerous. Delay and/or over-response in the throttle control's action may create skids on wet and icy roads. Less experienced drivers may become un-nerved by this kind of throttle response. Toyota's response to complaints consisted of these replies: (listed in the order in which they were given over multiple service visits) 1. "we know what it is. It is the fly-by-wire control. They all do it and the owner has to live with it" (spoken over the phone prior to the first service visit) 2. "operating as designed".. "this isn't a safety issue". 3. "the Camry have a driver habit imprint feature which adapts to the driver's style". 4. "the car is pretty much normal". 5. "he has seen a few of these". (garage tech rep.) during service appointments, the dealership supplied three 4 cylinder, automatic 2007 Camry as "loaners". none of these cars demonstrated the same drive-train behavior. The writer has been told of two other Camry which exhibit the problem: Hey are serial #S: 4T1be46K27uxxxxxx and 4T1be46K87uxxxxxx a similar complaint is documented on-line in the "car and driver" magazine's user review.
