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.

Ineffective Reboots
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.

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.

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.

Out of trundle tiresd
Out of round is a condition that may have happened when the tire was made, so they should check for that as well. The old way to test it was jack the wheel up, put a coke bottle next to it touching the tread, rotate the tire and see if the bottle moves or falls over. I'm sure they have better ways now!
