What about a slight vibration felt through the gas pedal when you go above 80 mph for a few minutes?

This is a safety control issue. As other posters stated, the TSB's apply to vehicles listed on the bulletin. These are well documented problems which Lexus has acknowledged and addressed in technical bulletins applicable to vehicles described there. If your car vin is listed and the franchise manager doesn't instruct the service manager to install the remedies listed in the TSB's, let him know you will escalate to corporate--and if the vehicle is involved in an accident, every person in the dealership who failed to comply with the Lexus TSB instructions will be named as defendants in the lawsuit.

The dealer should be able to read the ECU to determine if the reboots were dated. The code on the ECU should be compared with the TSB code--wouldn't be the first time a service tech input a wrong number and didn't check his work. The battery must be disconnected for minimum 30 minutes, according to one tsb. If procedure isn't followed, problems will occur. If it is verified that the updates were done correctly, it's possible that a defective computer chip/components are causing the problem. Get the service manager to ride shotgun while you drive and demonstrate the issue.

Wrong thread. This one is about tire vibrations.

I am surprised there isn't a class action yet!

Has the dealer used “chassis ears” yet?

I have 2016 RX350 AWD. at 50000 miles I switched from Michelin to Bridgestone and it starts vibration over 80MPH. I read some reviews online for the Bridgestone tire, a lot of bad reviews about vibration.

New tires - make sure they are properly balanced and not out of round.

Dealer did the 4 wheel alignment for my vehicle when switched the new tire. Is that the problem? Dealer didn’t do the wheel balance.

JSracer

the definitely balanced them when installed, now rechecking or road force might be worth looking into
alignments won't cause a vibration

chassis ears, like for chasing noises, with the clip on leads ?? for a vibration ?? or the hi tech that reads frequency, that could work also. First-order tire/wheel vibrations usually produce a vibration frequency of 10-20 Hz

My 2018 F-Sport came new with Bridgestones. I have been pleased -- I never used Bridgestones before, but at 21,000 miles they are holding up well with zero problems.

Mine came with the Bridgestone tires, and there has not been vibration issue at high speed. Super quite tires too. Your issue could be with balancing...
Good luck

Will surely check in this.

reference post 160 for the TSB

An out of round tire is not as uncommon as might be thought. Have had this issue and was told by a Firestone service person to buyi Michelin' "They're the round ones"!
