I just took delivery on a 2013 GS350 F Sport over the weekend with 36xxx miles.
Right after half day of driving I realize squeak on brakes, dealership claims is new pads and
resurface rotor (funny thing is that it never squeak during test drive).
I had an appointment tomorrow back at the dealership to take a look, but even lexus mechanic say
this is common to all F Sport model quote "you gain some performances on F Sport package,
but will sacrifice on certain area." If that's the case this should be a factor recall.

Any chance you all think I can return the vehicle back to dealership and purchase a different model?
