I've been experiencing the same vibration problems. I feel it in my seat, the steering wheel and can see it in the visor. I'am hoping that Lexus will come up with a true solution to this problem, so that I can get back to loving my car.

 

Solution is already there. Get it road force balanced.

 

I think I flt this this morning in my car as well (and on occasion previously).

I checked the tire PSI and they were all different. What exactly needs to be said to the dealer to fix this? Just a simple re-blanching?

What were your tire pressures in the front and rear? For F-Sports tire pressure should be 36 psi cold front and rear and for regular and luxury version tire pressure should be 34 psi all around.

 

I recall 2 tires were 36, one was 34 and the other 33.

Pump them up to 36 front, 37 rear cold and see if that improves.

 

1400 miles on my Dunlops and the ride is still smooth as glass with no vibrations. It can be fixed.

 

I test drove a premium version with dunlops and the steering wheel vibrated between 45-50 mph for first few miles after sitting for 5 or more hours. I drove another one with absolute no vibration at all. So its a matter of tires. On my GS 350 F-Sport I am having this irritating flat spotting vibration that last for a long time before smoothing out and road force balance were showing the tires are very good. I am fed up with the Michelins on my car that I am getting them off for different tires as these Michelins were bought from tirerack and are defective and will get Bridgestone Turanza Serenity Plus (new version) or Michelin Pilot Sport A/S. ITs the damn tires as always. Not bent rims.

PS even with warm temps some of the GS from the dealer vibrate in the steering wheel and in the seats when driving off the parking lot after sitting overnight and the car feels shaky for a while which is very unusual for a car of this caliber and I guess its the sensitivity of these cars to the tires on them and how round they are.

 

I finally discovered I have this problem, too. I don't feel the shaking until I am going about 65-70mph though, which is why I never felt it before. I don't usually break 55mph on my commute to work in the morning.

 

What dealer in FL are you at?

I have the same problem with my GS in West Palm. I'm trying to have the tires replaced with Mich. I feel they ride better and last longer.
