that's interesting! I have a 2017 model with 21k miles. I get the hesitation quite a lot driving in NYC. Bummer though because my car is not listed for the fuel pump recall .. do we know if the list of cars for the recall are finalized or if more cars will be selected in the near future?

All North American market RX 350 & 450h models are manufactured in Cambridge, Ontario. I toured the factory, it’s state of the art. Your friend’s model has something wrong.

both used around 40K+ mileage. lag starts to kick in when rpms go above 3k especially when going on a freeway ramp. could be that he has a slow foot in the gas, and my foot is heavy and how the ecu programs it.

There's a good chance your's has had the TSB done, there should be a label under the hood showing that the TSB has been done.

on another note, I found a new discovery which I didnt know in my RX. My gas was low, and then it gave me option of nearby gas stations in GPS. I thought it was kind of cool because I never saw that before.

I checked today and I did not see any tsb label under the hood. When I press the gas pedal, power is immediately transferred to wheels on my car. on my friends car, there was 1 second delay, followed by rpm increase noise, then power started to kick in. The rps jumped from 2K to 4K, and it wasn't smooth at all. I told him about it, and to ask the dealer to fix it cause he still had warranty left.

Yes, get your friend to have the car checked out. Tell him to go out with the tech and to show exactly what he means otherwise they'll come back and say, "We couldn't find anything wrong". You have to be forceful with some of the dealers. Maybe there's something else wrong with it but I'd suggest he tells the dealer to install the updated software for the transmission.
Yours could still have the TSB done, I wouldn't be surprised if they didn't put the sticker on. Sometimes they put them in the drivers side door jam too, at the front near the dash.

I've never paid much attention to octane levels because up until this point all my cars have always used premium. Since I posted on this thread I was about to give up on the hesitation problem and then realized that regular here is 87 octane and plus is 89. Filled up with plus and the hesitation is gone. Simple fix for me.

I had the dealer apply L-SB-0032-19 to my 2017 Rx350 but it made absolutely no difference....same with using premium gas. This car is by far the worst Lexus I have ever owned and am desperate at this point and will try anything,
Where can I find more info on Pedal Commander for the 2017 RX350?
ANY other guidance/tips would be appreciated. Thanks so much!

I actually do drive it in sport mode but I feel like it makes the gas pedal overly sensitive (it sometimes just takes off when I apply a just a little bit of pressure).
I was hoping the fixes above may help since premium gas and the TSB didn’t. Thanks.

However, the Pedal Commander has no effect on the transmission (the source of the "hesitation"). It interfaces with the throttle control and speeds up or slows down the throttle response as you depress the accelerator pedal.
