Filed May 11, 2015 · Transmission · 125,000 miles · SC

Did not have a car accident, or experience any injuries or car damage, but this car, like numerous other cars of the same make, model, and year has some serious transmission/computer software issues at times. It hesitates and lurches often. I drove on the highway yesterday and the car acted up in the worst way ever.but it seems to me that with information on these same transmission issues plastered all over the internet, your organization would make toyota engineer a permanent fix for this problem, and recall and fix these cars.

I did not have a car accident, or experience any injuries or car damage, but this car, like numerous other cars of the same make, model, and year has some serious transmission/computer software issues at times. It hesitates and lurches often, especially in d4. I drove on the highway yesterday in d4, and the car acted up in the worst way ever. I later tried driving in d, and the car did better in town and on the highway, but it seems to me that with information on these same transmission issues plastered all over the internet, your organization would make toyota engineer a permanent fix for this problem, and recall and fix these cars. By the way, this car had the lexus software update for its transmission issues last summer, and I only use the highest octane gasoline. The car actually belongs to my elderly mother, which makes me very concerned about the possibility of her having an accident, or complete transmission failure leaving her stranded somewhere.

When I press the accelorator there is a hesitation in the car speeding up and while driving there is sometimes that same hesitation.

Lexus es 330, when accelerating, there is a hesitation. Dealer said it was related to octane of gasoline, that I should increase the octane to 92. This did not help. They lie at every angle...

2005 lexus es330. Hesitation & stumbling on acceleration. Also transmission will not downshift. This is a well documented problem with the 2005 model year es330. There was one revision of transmission software/firmware provided but it did not fix this problem. After several complaints the lexus dealer stated "there's nothing more we can do." several internet postings suggest that this "delay" or hesitation is designed in. Also, if while entering a highway, for example, the gas pedal is depressed, released and depressed again there is a much longer 2-3 second delay until power is delivered and to get proper upshifts and downshifts I have to shift the automatic transmission manually. The lexus dealer was/is very familiar with this problem but has no fix beyond what was provided for back in 2005 by lexus. This should be further investigated along with the current crop of toyota/lexus throttle problems. Thanks!

I have the infamous es330 hesitation problem which is part of the sub-standard operating parameters of the car. When purchased from the dealer new in 2005, I was advised after taking the car back several times, that updating ecc module probably would not fix the problem and it didn't. The dealership was very aware and blamed the lag on toyota's "drive by wire? Design used on this car. Further, they said lexus new about and probably wouldn't correct the problem until the next model year. The hesitation is especially apparent when pulling away from a full stop or when power is required to merge into traffic. To compensate, the driver has to keep pushing down on the gas until the car decides to accelerate -- then the driver has to quickly ease up on the gas to keep the car from over accelerating.

Transmission hesitates from a stopped position on my 2005 lexus es330 causing a feeling that the car may stall or lunge forward unexpectedly. I purchased the car a few months ago with 22,500 miles. I brought this problem to the dealer's attention and read about it online. Apparently, lexus provides a "flash" fix to the software. But, my local lexus service manager suggested not using the fix because, according to his personal experience, the fix can cause damage somehow to the car's computer that is irreparable. Apparently, the fix is not always a good fix. I was told the fix cannot be set back once it is been addressed. It is my understanding thousands of lexus dealers have been effected. Also, occasionally I feel like my car lunges forward suddenly and briefly for no apparent reason. Any guidance you can provide about these matters would be appreciated.

Acceleration problem with lexus es 330 (year 2005). Having been experiencing this problem for some time (have taken my car to dealer ship numerous times and filed law suit through the lemon law) and lexus continually advising that car is working properly. I was almost in a very serious accident last night as a result of the acceleration hesitation problem.
