My '16 RX350 is in for its 40,000 mile service now. They said I needed a brake flush at 30,000 (129.99), fuel system saver package ($288) and and A/C refresh ($89.99). The tech said each dealership has different suggested maintenance and I had my 30,000 done at a different Lexus dealership and it wasn't part of their package. Leads me to believe I don't need it. It's not on the maintenance schedule for the car at either 30,000 or 40,000. Neither this dealership or the last one mentioned anything about the services you said they recommended.
Seems to me the dealerships are full of unnecessary suggestions.....
