Picked up car yesterdeay.
Yesterday, dealer called me and said that they hooked up the scan tool but could not find anything wrong. So they needed their rental back. The foreman agreed that the transmission on these are not very smooth and there is nothing he can do. Everything is computer controlled so there is nothing to adjust. Going up a slight grade or going down a slight grade, and sometimes on flat surface, when the transmission wants to upshift or downshift, sometimes you will feel a jolt. Again, there's nothing they can do. They do realize it's an issue, but it's not a problem, huh? The only thing they did, was to reset the transmission computer so that it can relearn my driving pattern. They said if I wanted to escalate this to contact corporate. Regarding the power, to make this car go a little faster, you really have to step on the gas.

ECM Transmission update
Thanks DocT. Last week when I met up with them, they did mentioned that they updated the ECM transmission but I don't know if I feel any differences with the transmission shift. It's still rough shifting sometimes.

What kind of mileage are you getting. If there is something that wrong with the motor, your gas consumption would be terrible.

As a point of reference, a Car and Driver road test of a 2016 Land Cruiser showed 0 to 60 at 6.7 seconds. LX I'd expect to be slower by less than a second.

Here it is a trick I have used in my BMW after my wife was driving it for a while and became sluggish. 1. find a big empty parking lot 2. Disconnect battery for 5 min or so to let things reset and connect back in 3. Turn on the car and punch gas all the way down, stop the car and turn it off. 4. repeat step 3 couple more times.
Above should help computer to learn your behavior. Of course over time things will come back to sluggish if you don't drive aggressively enough.

Might be long shot shot but After driving for a while maybe 30-50 miles get out and touch each rim, for not more then a micro sec or get a temperature laser . My rear wheel used to get hot and I also felt not enough power, turns out my one brake pad was stuck. I never heard any sort of noise or anything.
Back in December, I bought a brand new 2017 LX570 off the show room floor. I did not have a chance to test drive it before signing the paperwork because the whole buying process was long and they were rushing us because it was getting late. Well, 4,600 miles later, I brought the car back because of rough shifting, abnormal clunk in drive line when letting off the gas and accelerating again, and loud clunk when gently accelerating while on a medium incline, not steep. Another major problem I had was the lack of power. I own two Honda Odyssey, an 05 and 06 Touring, and they were both more powerful and has more consistent shifting than the Lexus 8 speed.
So, last week, they dealer let me test drive a brand new 17 LX570, and I couldn't believe it. As soon as I started the engine and revved the engine, it sounded much livelier. As I accelerated, I could feel the power against my back. This feels more like 0-60 in 7.3 sec.
The one I bought, felt heavy, and sluggish. 0-60 feels like 9 sec. This is a heavy car so I just thought it was normal. It feels as though, I am missing 80 hp.
The dealer is keeping my car to diagnose and they lend me a brand new 2017 LX570. This one also feels a lot more powerful than mine. We'll wait and see what happens.

Just picked up a 15 CPO with 27K miles and when I hit the gas it's very fast for a 6K car. 400HP doesn't feel slow or sluggish unless I feather the gas like I do in normal commute mode.
If you're using slow or sluggish, something must be wrong.....escalate.

Call and escalate, bring it back again and again. It took 5 trips to the dealer with a complaint of a knocking noise from my engine at idle before they tore the motor down and found more than 1/2 of my valve springs were failing in my ISF. You have to be persistent and noisy to get help from Lexus. You are the original owner, they should do a lot more for you. If the other two ‘17s you drove are different there is definitely a problem.

A. Your truck, operating properly like the new 2017 you test drove recently
B. Your money back
At this point you'll just have to keep escalating. I suggest calling corporate and taking it from there, let corporate work with the dealer. CSI (customer satisfaction) is KING with Lexus, so they will see to it that the dealer delivers. Again, all this is assuming that there is something wrong with your truck, which it certainly sounds like there is.
