Hesitation problem at various speeds (TSB info post #159)

If you want more response just put it in Sport + mode. Running the 350 in normal mode sure is unresponsive, and does lag along.

Hard to make horsepower or torque at 1000 RPM.

I do have to say however that it has Michelins on it vs my 450h F-Sport and it has a much better ride than mine (Bridgestones) on the softest mode. Don't know if that's the vehicle or the tires.

Or it could have been filled with sub-standard gasoline, or it needed a new fuel filter, or lots of other reasons. An entire car line isn't necessarily terrible because of one negative experience.

the dealers on have regular fuel in their tanks. They will run just fine on it.

I agree with you OP. I was going to make new tread in regards to my new 16 RX350. I thought something might have been wrong with the car because in "normal" mode there is a big lag when accelerating from a dead stop. I guess it normal.

This is why I will kick it into sport mode when on those streets.
And this does not happen when setting a while like at a stoplight. Is this really only in FWD models?

Try again with the sport mode on. You should notice the difference immediately, but the MPG will be cut nearly in half!

I agree at times especially on HWY you really need to get on it for it to move, I blame the 8 speed but I am no mechanic or engineer.
What else is odd is if I leave on sport mode I get slightly better MPG which is really strange, but it is mostly HWY driving.

Yes, putting the car in sport mode does relieve that issue. But having to enable sport mode everything i start the car is a big inconvenience to me. I wish there was a way to program the car so that in would start in sport mode everything time. The "Normal Mode" driving dynamics for the RX is really ECO mode for other cars. Doesn't make sense too why lexus programmed the tranny this way. I haven't even touch ECO mode yet. I can only imagine how horrible that is. The RX is my wife's car, and i use a 15 Toyota Sienna SE as a daily driver. Driving the Lexus is much smoother and quieter, but i can honestly say i prefer the driving the Sienna due to frustrating lagging/jerking acceleration of the RX.

I mentioned in a thread a while back, that another option available to us in the 4RX that most don't even think about is to slap it in manual mode and hold the shifter forward 'till it indicates 8th gear. In this mode the upshifting is notably less "harsh" than in D-normal. Even bettr do this AND put sport mode on. Very nice combination. We do have several methods and modes to choose which is nice.
005-ECO mode is not too bad. But it'll want that top gear ASAP as in normal.
Several people have reported in here that they have gotten better mileage in sport mode. This makes sense because you are holding out each upshift longer which moves your 4300lbs to speed more efficiently sooner. This means less push on the gas to get to speed like in normal as you fight the premature upshift demon in this thing.

Transmission Clunk
Has anyone noticed during slowdowns into traffic from high speeds I experience transmission clunk going into low gear when drastically slowing down, I also get it if I am going slow and then almost floor it to say merge into another lane it like slams into gear. I remember getting this same low speed clunk in my 2000 GS it would always due.
It doesn't always happen but enough for it to be noticeable and annoying from 60K truck.
Hoping maybe they will come up with some kind of software upgrade.
