Even if you do have the dealership perform the "fix" all their doing is bandaging it up. Every single 2006 gs300 is going to have this problem and when it's fixed you'd be lucky to get another 70k out of the car, Those are words straight out of the service managers mouth. My car was 3 weeks out of the 9 years and corporate lexus told me they wouldn't do a single thing for me on my gs with 80k on it. There isn't an actual fix for the problem, the service manager told me he wouldn't perform the "fix" if I were paying out of pocket because it's only a temporary bandage. Bottom line, lexus sells garbage and doesn't back their product.

I will post more details in a little bit with pics too, but I was experiencing a similar situation with hesitation from a dead stop as well.
turned out it was exactly what u said... my air intake resonator had cracks.

OP have you checked your "Air intake resonator?"
I had similar situation:
Symptom's:
-low/rough idle
-intermediate hesitation from a dead stop
-hesitation between 1-2nd gear
-idle so low that it even shut off a couple times.
Fixes or repairs I tried:
-spark plugs
-MAF sensor clean and even put in a new MAF sensor
-02 sensor ( bank 2 sensor 1 ) = based on OBDII reader ( but didn't get a CEL )
-cleaned throttle body
-new air filter
***After the above fixes, my car seemed a lot better, but wasn't 100%.... what ultimately fixed the hesitation was fixing the Air Intake Resonator.
Below are pics from the fix itself... this is only temporary until the new one comes in:
As you can see in this pic, the part is cracking:
First I used some Foil tape:
Lastly used non residue duck tape to seal everything:
After doing all of this, problem is solved..... drove it around today for about an hour and feels brand new!!!

Thanks deadpool, No I'm not basing everything on one service manager, and no they aren't doing any black magic.... Clearly you don't know anything about engines or how they work, but thank you for your two cents and pushing other owners to spend money on a car trying to fix their problem but all they are doing is wasting time and money. The Problem with the engine isn't a simple misfire, the problem is that the engines were built with direct injection, so instead of the injectors before the intake valves they direct inject straight to the cylinder thus leaving nothing to wash the valves like a normal engine. Yes other car manufacturers have had the same problem but all of them are wrong in putting this product out to sell when it's not even good for 100,000 miles

You are correct genius, the injectors are electrically controlled to spray fuel directly into the each cylinder. Weather it's electric or mechanical it's still direct injection. And I am aware that gen2 and gen3 are two different generations, but thanks for checking. I'm not sure if I had a typo but I was stating that it will happen to every 2006 gs300 gen 3's, Not the gen two. And the only solution for a permanent fix would be replace the engine with an entirely differently designed engine. Replacing rings, pistons, valves and such doesn't change where the fuel comes into the cylinder.

Umm these engines do not have direct injection, they are sequential electronic injection. Clearly you can't read or do any sort of research, or you're on a rant campaign and you want other's *** to bleed for you. The 2006 GS300 has a completely different engine and is a completely different generation than the 2nd gen. Maybe you should of researched before you bought the car? I've read the rough idle GS300 thread in the 3rd gen section, plenty of people are getting it fixed AND plenty of them are lasting well over 100k before seeing any real issues.

And it's clear to everyone here that you don't know how to research. You bought the car thinking it was an issue that effected a small percentage of the production run prior to X amount of miles, well guess what IT DOES ONLY EFFECT A SMALL AMOUNT OF THE RUN before they rack up a ton of miles. And it looks of people are getting it fixed (or at least the ones who didn't wait 9 years like you did). So you just proved to us all that you didn't know how direct injection works, and that eventually it will effect all of those engines because you went ahead and bought the car anyway. No one has created the infinite mile engine yet, why do you expect them to re-engineer an engine for your 9 year old car?
