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

I've had my RX350 fSport for 11 months and brought it in twice for the hesitation issues. They did a reflash in March of this year. They said they noticed the vehicle had a shift hesitation on acceleration when trying to pass another vehicle. I brought it back the next month b/c the fix didn't last long. This time the same technician said the hesitation is now caused by me, said, I'm not accelerating very quickly and the vehicle is trying to accommodate my style of shifting. I now, always drive in sport mode b/c of the hesitation issues. I will be bringing my vehicle back next month for my 15k miles check and I want to get tough with them and not pick my car up until they do what is necessary to have a safe driving vehicle. My question to this group is...what do I tell them to make them understand this is NOT b/c of the way I'm driving. I love to drive fast and I love to be able to move into Interstate travel going at least 60mph to accommodate the already 70+ mph drivers so I can merge safely. Short story...the other day my vehicle was in sport mode and a Nissan was on side of me at a red light. So I though let me see just how good my car is doing. So when the light turned from red to green we both took off like crazy right, NOT! Nissan left me standing almost still. No pick up on take off, but the Nissan was flying low let me tell you. So this car has nothing to brag about in my opinion. Please help! Tell me what I need to do to enjoy my beautiful vehicle.

Bad news, gang. I've got a '17 non-F Sport and took my RX in for service today. Confirmed the correct TSB and update and was told by the tech that I have the updated software already installed, however, Lexus tech confirmed that the most recent update is a patch for the final update which is in testing. I can tell you that over time, your Lexus will exhibit similar hesitation and jerking.

Dropped the car off at Sterling McCall Lexus in Houston to apply this patch and the service advisor called back this afternoon saying "there is no code display. Tech test drive all three modes --eco/normal/sport-- car drive as normal". No fix is necessary. ????

Ask them to reset the transmission ECU so it starts the "learning" again. Worked for mine.

The RX 350 F sport or not, is NOT a sports car. I have an F sport and it`s slow. If you were trying it against almost any Nissan, yes you would be left standing still. Maybe you tried it against a Nissan GTR ? Hesitation is maybe 1 second, but feels like forever...Best bet is to drive in Sport + all the time, you will probably enjoy the vehicle more....but she's still no rocket!
