Hey thanks! Maybe I should have 
My GX pulled to the right and the checked the alignment. It was the passenger caster that was off so they corrected it. The truck drives straight now. Maybe very slightly pulls to the left, but I need to drive more to see. At least right now, I don't need to constantly adjust the steering wheel.
What was the problem with your alignment? Could you please share your story with us? Thanks again.

On a side note, it's not directly Michelin but BFG who is owned by Michelin. I had 4 KO2s replaced under warranty as they were ALL out of round. Similar to your experience now, it was a major PITA to get fixed. Road force, multiple shops, tons of time wasted.

Thanks! What kind of Michelins are you running? Right now I am pretty happy with the ride on the Defender LTX. The only issue I have now is some minor seat vibration and movement on certain road surface going 65-70mph. And just to confirm, you don't experience any of that?
So the issue was pretty much the OEM Bridgetones or them being out of balance to start with. It would have been a long shot to push the dealership to replace the Bridgetones with Michelins. I had the wheels checked at Discount Tire by 2 different guys and their machine, they are all good. By the way, most DT stores around my area now have the latest Hunter Road force Elite balance machine with some fancy laser tech that can detect out of round issue pretty quickly and accurately.
Thank you for your response. What kind of vibrations on the GX did you experience if you don't mind me asking? Did you have the dealership re-balance them or a tire shop? Did they actually do road force balance? If they did, do you happen to have the road force # report of the tires?
As for the weight, I haven't seen them do the "banged on" weights on modern vehicles any more. Probably due to aesthetics. All I see are stick on weights.

I realize it's a new car but I would check your driveshaft is properly lubed... and the bolts are tightened to spec on the entire driveshaft. Sounds dumb I know buuuut, it may be as simple as they didn't properly do the pdi on the vehicle... wouldn't be the first time.

I have owned a 2010 GX460 for the past 2 years and just hit 80k miles. I have been plagued by excessive steering wheel vibration for the past 5k miles when driving between 65-75mph, usually on roads with a slight curve. The steering wheel would be turned about 10degrees to the left or right before feeling the annoying vibration. I would feel the fluttering when driving straight. I had one of the local Lexus dealerships perform road force balancing which did not produce positive results. They gave up stating I needed to replace the Bridgestone Duelers that only had 16k miles on them. Took it to another shop for a 2nd opinion and they re-did the road force and moved the wheels with higher road force values to the rear. This did reduce some of the vibration but I was still disappointed.
So, I purchased the latest Continental CrossContact LX25 tires and went back to my shop for road force and alignment. It was considerably smoother for the first 2 weeks and then all of a sudden the vibrations were back. Unsure if some of the tape-on weights fell off. Went back to the shop and they slightly tweaked the weights on the front tires and then positioned the heaviest part of the wheel/tire to the lightest part of the rotor. Apparently there are markings or divets on the rotors and wheels. It seems that this latest effort has done the trick. I have driven over 50miles and the truck feels so smooth! No vibrations or flutter. Hope this helps those experiencing the same issue.

Thank you for sharing the info. This is actually the 1st time I've heard about putting the heaviest part of the wheels to the lightest part of the rotors.
Is there anyway that you can get more information on this? Like how to identify the lightest part of the rotors? This might explain why some people get vibrations with just a tire rotation when their cars ride smooth before the rotation.

Just thought I'd chime in with my experience, as I have a 2014 with 96K miles and no vibration problems to speak of at any speed. In fact, it is the smoothest truck-based ride I've ever driven. Tires are Cooper Discoverer SRX and they're super smooth.
Just wanted to add my 2 cents because I call BS on the dealer saying the vibration you've described as "normal for the GX."

Update: I made an appointment today at the Lexus dealer to test drive with a master tech. He seemed like a really nice and knowledgeable guy who's been with Lexus for 20+ years. We drove the GX on the very smooth road and then uneven concrete surface.
He agreed that there was some minor vibration on the floor board and the seat bottoms. But that's normal for the GX. He explains again that it is in fact a truck with stiff spring rates so the vibrations are easily transferred into the interior as it is. During the drive, I also thought that it is very smooth on smooth road and the vibrations I feel is more pronouced on uneven concreate surface.
So I went back to the dealership and requested another test drive with 2 other brand new 2019 GXs. They had Michellin Latittude HP tires on them. Guess what, they drove about the same as mine. Meaning, I felt that same slight vibration on the seats and floorboard.
So at this point, I think I'll take their words and just enjoy it as it is LOL. BUT there were definitely issues with the Bridgestones to begin with.
So to rate the smoothness again at this point:
9.9/10 on super smooth road surface
9.5/10 on uneven/broken concrete surface
If anyone who's from Houston, TX and thinks that their GX is super smooth on all surfaces and would like to help me out and doesn't mind me test driving it, I'll gladly buy you lunch or beer or something

I have Bridgstone tires on GX460 2018. I did talk to the dealer about sending an inquiry to Lexus Motors technical adviser to suggest any solution but I haven't heard any thing back from them! I did drive there new 2019 but it had the worse shaking and vibrations at 40 and then between 60 to 70 mph. I plan to continue to pursue this issue with Lexus till they come up with some solution!

GX460 Vibration
I've had my 2015 GX460 for 16 months. The vibration started ~8 months ago. I've spent almost $4K trying to get rid of it - new tires, brakes, alignment, balancing, road force balancing (as recommended by Firestone) + new bushings, shocks and struts (as recommended by Lexus). None of that has helped AT ALL, and the vibration is getting worse! I don't allow clients to ride with me anymore, and am PISSED off to the highest degree of pisstivity about all the $$$ I've WASTED. Lexus needs to come up with a solution, and make this right!!!

Are you still on OEM rims? I thought I remember somewhere... maybe other forum(s) someone saying they had a similar issue and it came down to a rim that for whatever reason was bent in a way but it didn't show up on the balance gear. I could be having a false memory though.
