Having traded my gas-hog GX for a new RX, I am pretty happy overall. The car is comfortable, sufficiently powerful, and endowed with some features that the GX didn't have (such as HID headlamps that swivel, a power liftgate, and fold-flat second row seats). But I am a bit disappointed at the rattling sunroof shade and another rattle emanating from the right front dashboard area. I try to remind myself that I'm getting better mileage to counteract the annoyance. But after driving only 300 miles so far, I hope this doesn't foretell a future of other things going wrong.
Navigation system--they finally removed the "lawyer screen" that required punching "I agree" every time one started the car. The power liftgate is a real convenience too.
Focus on the niggling problems of workmanship characterized by these rattles. After owning 11 Lexuses (or should that be Lexi?), I can state that the RX is the only model with this kind of problem.
