PWMDMD, the bucking seems to be only when the car is first started in the morning and leaving the driveway with a light throttle. The dealership cannot make it happen because they are on a very busy 4 lane road, which is rt 9, so you cannot leave their place without hitting the gas to move with traffic. This is why maybe they can't produce the bucking, your going too fast in the first place. So, they should be telling me this instead of refusing to apply the TSB.
Common sense you think????

Talk about a different experience, I was in tor the 20k service this morning. My service advisor found the TSB and said no problem, we'll take of that. Why not do the drone TSB while you're at it and he said you need a part for that one, I'll order it and it will be done when you pick up your car. You loaner is parked out front.
Your dealer sucks, big time.

I had a small rattle in the door, wasn't a big deal but thought they may know of it and how to fix. The service guy suggested his senior tech and I go out for a run to show him the rattle, we drove around for 20 minutes, seemed to have all the time in the world to help. That's the type of experience I expect and have received so far with Lexus, shame some dealers aren't playing the Lexus game.

Having gone through two ineffective TSBs on this issue (first and most recent), and reading the most recent TSB, Im starting to wonder if the ECM/PCM needs to be replaced on my car. I've always thought it was software related as I've driven many other RXs without the issue. Reprogramming has not worked, but I am convinced that Lexus knows the exact issue as the description they use is spot on. There are some days and some roads where the issues are less pronounced, but I still deal with the hesitation, bucking, and surging on a daily basis. It's refreshing to drive my 20 year old Toyota truck that has great throttle response and a smooth predictable transmission.

Re TSB 0032-19, here's my theory. We know that the bucking, and I use this word because it is in the title of the TSB, is more pronounced in eco and drive mode than it is in sport mode therefore many only drive in sport mode. I think that the newest TSB moves eco and drive towards sport and I say that because I feel that eco and drive are now more sensitive. In other words now when I step on the pedal I don't have to push as far to get the car moving, before it was dull and now it is a bit more sensitive. Is it now the same as sport mode, not even close.
At least this is my completely "subjective" theory. Does anyone else feel the same??

Yes, I thought of that. I could not tell the difference in sport or sport+.
I recently experimented using 1 full tank in eco and 1 in sport, I did this twice in similar driving conditions. In one, eco was slightly better and in the other, sport was 1/2 mpg better. Not very scientific, but still I was surprised at the results. And even if eco was always slightly better, for me the mapping update would still be well worth it.
