My vehicle hesitates or pulsates between gears especially at 40 mph/2000 rpm when accelerating from a stop. Tachometer also pulsates. At steady speed (not accelerating) the vehicle runs great. The Lexus Engineers can not fix the problem common in 2017 & 2018 Lexus RX350. Lexus dealership diagnostic specialist and I went for a ride for several miles while he recorded data from my vehicle,via laptop computer, to be forwarded to Lexus Engineers that are currently working for a fix for this problem. My 2013 Lexus RX350 (6 speed transmission) had no problems. I probably should have kept my 2013 instead of trading it for my 2017. My 2017 Lexus RX350 (8 speed transmission) definitely has a problem that Lexus is aware of but can not solve. Hope you could light a fire under the Lexus Engineers to solve this problem.
This is a forum of people , non of which have any influence with Lexus . Not sure who you meant to send this post to.

Agree with @VOLVO_V70. If you want to light a fire under them, take it back to the dealership, concisely explain what your problem(s) are, then let them go to work. You have a factory warranty, use it!
