No repair of any kind ever needed since I bought this car new in 2011. Just regular maintenance. Had the same story on my previous RX350. Unbeatable reliability. It's no BMW (I have owned a couple of those) but you feel firmly in control in any highway or city situation. Wife and I are older, and we appreciate the ease of getting in and out plus the advantage of sitting higher than much of the traffic. Very comfortable ride and satisfactory all around vehicle for normal driving. Son-in-law has one just like mine, someone pulled onto the highway right in front of him with traffic at 60mph. He swerved to avoid the idiot, got bounced back and forth between an oncoming pickup and another one behind him, rolled 4 times, all 11 airbags deployed and he crawled out of the sunroof with just a sore neck. His car was squashed front and back. Automatic fuel cutoff and doorlocks. That's pretty good safety.
Purchased in 2013/this app won't let me enter the year. This is my first Lexus, and I've been really pleased with the vehicle and dealer. My only complaint is the stone chip problem -- the paint has only to look at a stone, and it chips. Touch ups -- even those done by my body shop -- don't seem to stick.
This SUV is everything you expect in a Lexus: comfortable, quiet and reliable. A couple of the features I really like are the steering headlights and the ventilated seats. The only real disappointment is the navigation system which only allows voice access when driving, which really limits what you can do with it. For example, you can't get it to look up a POI in a given city, it will only tell you POI's near you.
