The Mechanic should do it to make sure everything works and you don't have another visit to the dealer. I suppose if things are missing like sport + and customize, plus runs poorly, you have nothing to lose by pulling the negative lead on the battery.

Same issue with mine, no sports + or customization screen...plus it ran like #$%...If I knew I had to disconnect the battery I would have done that myself. I believe you disconnect the negative terminal..Check further up in this post to make sure...someone posted the correct terminal.

Brought my car to the dealership for it's first 5k miles and while there I requested they fix the hesitation issue. They must have applied the TSB and my car is working better but I don't know if they disconnected the battery. My car still hesitates a tiny bit but the pick up is much better and seems to drive better than ever. Never had a vehicle handle poorly like this one has these past few months.

Okay do you mean my preset stations when you ask "Do you still have sport + and customize options?" Not sure what you're referring to or what to look for? I've been paying so much attention to the hesitation I've not noticed if I feel it downshifting or not. It does have less hesitation but today when I drove it I felt more hesitation than the weekend. But the pick up is much better. I feel a bit safer pulling onto the highway now rather than waiting for all cars to pass then pulling out into the road.

The TSB is a reflash of the transmission shift points onto the ECM. I was told by the Service Mgr that it is specifically 3rd and 4th gear that causes the majority of the problems, but the whole shift map is redone from what he said.

I picked the new car over the weekend.. looks like it may have the hesitation issue too,should I wait till 5K service or should I get it reflashed ASAP? Any suggestions?

There is a VIN number interval in the TSB report that will let you know if your car is affected by the hesitation issue, you can double check your car. It affects 2016 and some 2017 models.
The 8 speed transmission for fuel economy reasons is the major reason why there will always be hesitation sometimes. I and other family members have had these types of issues with vehicles with more than 6 speed transmissions.

Well, after a week of driving with the TSB, I still stand by my 80% improvement rating. The throttle response is definitely better, but there is still some hesitation at certain speeds. I can't quite pinpoint it, but it just doesn't feel completely smooth or refined. An additional downside that has becoming more apparent is that since the transmission now spends more time in 1500-2000 rpm range, the exhaust droning is more noticeable.

I am now worried this may be an issue on my new 17 RX350 F-Sport. I downloaded the Canada TSB that another user posted a few pages back but is the US one different?
See attached, this one shows a VIN number but another user mentioned a range. How do I tell if my VIN is affected? Sorry this is semi-new to me for recalls and was not sure of the process. Thanks in advance!

Hey 17RX350F, if you look at the last six digits, if it is before that number for the F sport (I assume you have that version with your username), then it is affected by the TSB. My 2016 RX F was 05xxxx so it was before the 060921 VIN cut off.
