Dealer just told me my brake parts are available for order . Hope this also fixes the vibration issue as others have claimed

Sorry to hear your experience. I will say if you had expectation that your GX should “feel” like a BMW X5, then it will not. A more proper comparison would be to a pickup truck or other BOF suv.

If feeling nothing is what you’re looking for, go to a unibody bmw, audi, porsche, infiniti, acura, cuz no 550 will “feel” as smooth as those

On the other side of the coin, none of the other luxury brands i listed above have the offroad or towing capabilities of your 550, as you bought a luxury capable off-roader, not a pavement princess

Have you driven a LX570, LX600 or GX460? I have and the they all have BOF chassis and are smooth with non of the roughness of the GX550. This has nothing to do with unibody as the engine is rough at idling.

Edit: I agree that the unibodies with be smoother, I wasn't trying to compare the overall vehicle smoothness, just the engine. Maybe I should not have brought up the B58 as that is probably the industry benchmark for inline 6 and the GX has a V6.
