#1029 of 1407 2005 ES 330

Yes, I have the same problems with my 2005 ES 330. I took the car back to Lexus the 2nd week and complained about the hesitation, lurching and lack of acceleration. I have even had the experience, on the freeway no less, where I came to a sudden stop and the transmission made a sound like I was being rear ended. I was told by the Tustin Lexus lead mechanic that it is a software problem and there is nothing I can do about it and to start using 91 Octane gas to minimize the problem. I have been doing that, but the owners manual and Consumer Reports says you should use 87 Octane. I was also told they changed the spark plugs to hotter burning kind and they need the higher grade of gas. So, who is going to pay for all this more expensive gas? Why isn't Lexus doing a recall on these cars and taking them off the show room floor before someone gets killed. I need immediate response when I step on the gas on So Cal Freeways, no delays.
I have now taken the car back 4 times and I am currently driving one of their loaner SUV's. It does not have the problem.

Nothing is working for me. I have had my 2005 ES 330 since August and have taken it back to the dealer on 4 occasions. The car hesitates, lurches and even makes a sound like I am being rear ended if I stop to suddenly. I was told to put 91 Octane in to minimize the problem, but it does not help. I just have more power. The car is now at the dealer again and I am in a loaner. It did the above on the test drive and the salesman at Tustin Lexus said it was just cold. If I new the truth, I would not have purchased it - dumb me!

If it were me I would leverage the salesman if he/she is still there. Politely ask that you, the salesman and the service manager have an opportunity to drive yours and another on their lot back-to-back. Assuming the other vehicle doesn't exhibit the hesitation, demand firmly for them to make your vehicle drive like the other...
It's good news you are in a loaner. When you pick up the vehicle, tell them you want to go for a spin and see that they've fixed it. If it isn't fixed, then politely/firmly recommend the test drive. Get your salesman engaged and bring up the issue of being told "the unit is cold". If there is a software problem, tell them you want your vehicle loaded with software the same as the unit that doesn't experience the hesitation.
Have the situation documented.
#1032 of 1407 ShudderGuard Flush Kit
Jan 23, 2006 (8:07 am)
This "ShudderGuard Flush Kit" is an aftermarket product, really not a Toyota product. What it does is a tranmission flush kit (added before flushing, and an additive to the new transimission after flush). It changes the fluid's frictional behavior. I guess it helps. Actually, any add-on product that will change the viscosity of the transimmion fluid will change the driving behavior - but not recommended by the manufacturer for sure.

RE: Lexus 2003 ES300-I don't know if it after market or not, but Toyota is the one who added the shudder guard flush kit and I didn't even acknowledge to them that I had a shudder problem.Whether recommended by the manufacturer or not ,I'm sure they wouldn't have put it in if it was not recommended by the manufacturer or would have any effect on the warranty ,I'm sure they know what Lexus recommends as they are basically the same vehicle and take the same parts.

Well, I tried to manually shift the transmission for a few days, and it actually made mine respond even worse. The jerkiness and hesitation was amplified. It even started to have shifting issues when accelerating, rather just when decelerating.
At this point, I have just parked the car in my driveway and am driving our Suburban instead - I can't stand the car THAT much, that I'm willing to drive a clunky oversized gas guzzler!
It will just sit there while I wait for the notice period to be up so that I can file my DTPA suit and lemon law claim.....

I was curious, have you tried arbitration? It would sound to me like an independant arbitrator would validate your claims and force resolution.

I posted this FYI with your comments about the issue in another forum. Hope you find it informative.
Here's some really interesting info. Like it or not,it's worth reading.
My Internet research reveals there are at least Four (count 'em---4!!)Aftermarket Suppliers of "Transmission Performance Programmers", also called "Power Control Modules", sometimes called "Automotive Performance Computers" which are able to modify shift performance, shift points, shift firmness, and a host of other parameters for 4,5,and 6 speed automatic transmissions on every make or model of vehicle on the planet.
That tells me (1)There's no mystery or black magic to this issue, (2)The so called "unknown fix" isn't unknown--likely Toyota included, (3)A lucrative market exists for people to change the way their trannys work--not just Toyota/Lexus, (4)Cost is modest--prices range from $125 to $400 depending how sophistcated one wants to go.
All the confusing technobabble aside, in layman's terms, I no longer believe it's the mysterious and elusive quest we've all been obsessing about.
That said, here's what I think this issue boils down to.
All manufacturer's DBW throttle/transmission systems have unusual or unfamiliar characteristics. I believe those Service Tech's comments about it being a "normal" characteristic are probably correct. I believe it's likely a consistent phenomenon across the board--typical to a greater or lesser degree to all manufacturers. Auto manufacturing consistency today is higher than it's ever been, so anomalies like some suggest this may be aren't too prevailent any more.
So I believe that complaints we are seeing have more to do with a few owners having adverse sensitivity to the issue, and most owners not noticing it nor being bothered by it.
More research results. A small sampling to be sure, but revealing nonetheless.
Since coming into this issue last October, I've driven 12 Toyota/Lexus products with 5 speed BBW in addition to our own two cars. Lexus 330 and RX series, Highlander, Avalons, and Camry. None has exhibited any of the delay, lurching, seeking, or prolonged hesitation. All have been seamless, smooth and quiet. I have yet to experience any of this phenomenon, and I have yet to speak directly to anyone who has.

Of the 50 or so people I polled over the weekend here for the 24 vhours of Daytona the only ones with the type of hesitation complaints described in the TSB seemed to be exclusively FWD Toyota or Lexus owners. And just as we see here not all owners were experiencing the problem, some seem to not even grasp my question without an explanation.
I had the opportunity to drive a number of rental cars back to the rental lot, almost all FWD, and not a one of them exhibited the symptom, including my own Chrysler sebring, insofar as I could tell.

Wwest, would you say that the 50 owners represented a fair and equal crossection of manufacturers? Did you ask an equal number of Honda/Acura, and other owners before reaching your conclusion?
A search of NHTSA records and interviews with Consumer Reports magazine also show owners of other car makes are suffering from the same hesitation problem, including BMW's 3 Series, Ford Explorers and Escapes, and Dodge Durango 4x4.
David Champion, senior director of Consumer Reports' Auto Test Center in Connecticut, said the magazine's testers have encountered the same problems in the Audi A6 2.7T, the Audi Allroad, the Mazda6 equipped with the V-6 engine, and the Volkswagen Jetta 1.8T.
