It's hard to issue a recall on the ECM for a problem that may affect a tiny % of cars - quite possibly a problem so small Lexus hasn't even defined it as a problem at this point. It's also a stretch to say the unintended acceleration problem in 2009 was caused by the same problem. You are clearly emotional about this and you should be - what you described sounds scary. I think you're options are to report it to Lexus and try and help them find/identify the problem (could be something as simple as a randomly malfunctioning computer that is easily replaced and not a systemic problem affecting many cars) or getting rid of it. No one will know until Lexus investigates and no I'm not convinced a single report is going to mobilize Lexus engineering to descend on your dealership for emergency diagnostics and testing but it starts with reporting it Lexus.

I did the TSB today in Canada. I will try to see is there any difference.
I also notice if I switch from drive to reverse and I hold the break, I can hear a noice. If I do not hold the break, I cannot. I am not sure if it relates to transmission or break.
Is there any one has this issue?
BTW, I also replace my drive side outside mirror because I can notice some vibration when speed reach 110km/h or the road is too bad. Still notice the vibration on bad road and I will check in highway later.

The first incident of this problem was reported to Lexus, by me in person, on August 8, 2019. They did not try to replicate, and proceeded to address the hesitation issue with a computer re-flash. No change. I’ll be talking to Lexus again soon. Thank you for your response.

Not sure where you are located, but I would also report it to https://www.nhtsa.gov/

Attached is the 9/26/19 revised/updated TSB. Don't know if it contains actual ECU remapping optimizations based on feedback or just updated coverage information. Print this out and give it to your service advisor. Mine claimed there were no "recalls" and the master technician had to inform him the TSB are different from recalls.
I had the TSB done and oh boy the normal mode now drives like sport mode. It's amazing. The gears are shifting so smoothly. I don't think it's placebo either because with the loaner NX300 I was given I thought to myself "this is how gears should shift."
And remember to take a ton of photos before sending your car away. I was too trusting thinking these guys deal with Lexuses everyday and that they must be super careful but nope. There's now a 2 inch scratch on my rear bumper, deep enough that I can see the dark plastic. The SA said he'll forward the issue to the customer relations and the service manager and I'll hear back by Monday or Tuesday since they don't work weekends. The funny thing is I have a $600 dual channel dashcam with $400 in backup batteries but I disconnected it to be nice and to give them privacy while they worked. I'm a goddamn moron.

Unbelievable!!!
What's this, the 3rd attempt to rewrite the software.
I try to be positive with Lexus but really, what the hell are they doing. And this TSB is a Revision so likely that anyone requesting it will end up with the original. Why not give it a new number?

Now car changes gear too soon and end up to jerk feeling %50 of time when changes the gear. my smooth Lexus turned into a rocking chair now. BE AWARE
it happens more in down shift if you decelerate fast and sometime in accelerate there is a surge. (do you have this issue after TSB done? (L-SB-0032-19)
I went back to dealer and asked to put original ECU software (revert the TSB) but they say they can not go back and downgrade the software. Do you know if this is true?
