How long is the delay when the problem occurs and how often does it occur? Does it occur mostly or more in any particular circumstance, such as a turn? Did you trade or sell the 2012? If you traded it, did they take into account the problem in determining the price you got?

When this forum started two years ago, I was sure that this transmission problem affects small number of RX350 and I was one of those unlucky individuals. The number of forum participants proves otherwise. It is very strange that LEXUS still does not admit the issue and did not come up with solution. Does anybody know how to handle situation with such a widespread defect?

"Motorweek" review 2013 Volvo S60 T5 AWD
"There's a little hesitation at launch and you wait for power to build fully."
(At the track)
"With that throttle that's a little slow to respond at times, the T5 feels much more powerful in passing situations than off the line."
I wish these friggin' engineers could remedy this DBW lag design flaw.
Look at all the different manufacturers mentioned in this simple search:

Update. Just got my 2012 RX350 back from the dealer. Lexus technical advised the dealer to top up the transmission fluid and OVERFILL it by 200 mls and clear the computer memory. I am to report back to the dealer and let them know how it's going. Doesn't sound like a solution to me, but I'm keeping my fingers crossed.

Has the hesitation on acceleration been resolved
First, I'm new to this Forum, and I bought a 2012 RX350 from the local Lexus dealer in April with only 600 miles on the odometer. Unfortunately, I have observed the problem of hesitation on acceleration several times -- a couple of times it was quite scary.
I noticed the last post in this category was 11/25/2012. Has the problem been resolved?

Um, people, have you heard of Traction Control? It has exact side effects described in this thread. Nothing to do with the transmission. Welcome to the 21st century.

Not convinced this is a traction control matter, vlad_a. I believe it more to be a nuance of the drive-by-wire system for the throttle and programming for the transmission. Not something new as 2nd Generation RX owners have been making the same complaints for nearly a decade now.

A simple test is to turn off the trac. No, it won't kill you in an RX. Provided you can turn it off, of course. My '13 450h re-engages it pretty fast.

That's an interesting assertion. Never ocurred to me that it might be tied to the traction control system. I wonder if people experiencing this throttle lag have tried turning it off and seeing if it still happens. Since it's an intermittent issue that can't be readily recreated, this would be worth trying.
BTW, can you even turn traction control off in a RX350? I don't think you can in an '08 400h. Too lazy to get up and check to be sure.

I know the 2012 and later are rated for regular, but has anybody tried premium in these cars and see if it makes a difference with the hesitation? I remember from the RAV4 forum that the RAV4 V6 has a similar issue, and people there recommend the use of premium to mitigate the problem.

after reading this thread, I have tried to check today if have this hesitation/acceleration problem with my new to me 2010 RX350 and did not observe any at all, I thought my pedal acceleration feels a lot more responsive compared to my GX470.

There probably is a sequence to turn T/C off in all Toyotas but it's a convoluted procedure to say the least. I was wondering if there's a "hard switch" in the RX350 that does it.
