My wife loves the car(SUV?), but my first interstate drive of any
distance revealed significant wind noise that seems to come from the
junction of the windshield with body. Also, when flooring the RX330 to
smoothly merge into fast moving traffic, the tranny balked like
nothing I have ever experienced before downshifting into far too low a
range?!? Guess I should have manually shifted it down a notch?!?

Compared to my Honda Accord EX V6 tranny, the Lexus is a barking dog!!

The RX300 was noisier than the Accord. One's an SUV, the other a sedan.
Go figure!

Lexus' seem to have a trait of responding gradually to any flooring.
Euphemistically called a refined response.

The RX330 is a crude beast in terms of engine and transmission. And that's
coming from someone who traded a Yukon XL in for one (me). The Yukon power
train was much more refined.

Maybe the RX350 will be better.

Hard to imagine it being worse.

Lexus let one out of the kennel in this regard.

I have absolutely no problem getting my LS430 to get up and go.

The ES series, starting in 2002, is the same way. They sacrificed response
in an attempt to reduce emmissions and increase mpg. Turned out to be a
very poor decision, at least from the driver's perspective.

And it works.

I assume you mean a fix for the wind noise, because every "fix" they've
provided for the tranny behavior has not worked on my 2002 ES300. I would
expect that the behavior is the same across all models, Lexus just doesn't
have the calibre of engineers to produce an electronic ECU that works in all
situations. At delivery, my ES had a major lag at highway speed but worked
fine in all other ranges. The next version improved the highway speed issue
but screwed the thing up at slow speeds, such as a rolling stop followed by
acceleration. The third "fix" seemed to help but it went back to its old
ways once the computer "learned" my driving habits. In my opinion, the only
true fix would be to disable the adaptive learning logic and let it respond
to the driver's direct input, not some blended response based on what the
driver did in the past. Adaptive learning in the ECU seems like a real
screwed up concept to me.

Hahaaa (bitter laugh of an bitter Lexus owner), serves you right. By now,
everyone should know about the Lexus tranny issue in the ES series and
engines (and yes, the RX has the ES engine). For the helpful chap who said
he had no problems with the LS, that's because the LS has a different
trannsmission. Spread it far and wide. Lexus RX and ES series are deeply
flawed.
