I am very satisfied with the fact that in 1.5 years I did not have to take RX back to the dealer except for maintenance. After I traded my LR2 for RX, I look into my records and counted visits to LR dealer - 18 in 4 years not counting maintenance...

Comparing Lexus to Kia is not fair unless you comparing $50K Lexus to $50K Kia.
I would compare Rx350 to X3, Q5, GLK, MDX - they all are in the same price range.
Our Q5 is still very "quiet" after almost 4 years of ownership, and its engine is very quiet too even under acceleration. Audis do have a thick felt-like fabric under the plastic door panels.

Q5 did have two or 3 problems so far, but the ride quality and handling/cornering is superior to RX's.. (IMO)
