I have had two warranty repairs completed at Kuni Beaverton, as well as had the water pump on my GX460 replaced. Car repairs are never fun and, yet, the service team has always made the experience as easy as can be and have always been incredibly accomodating (bonus that they clean my car after every service). Listen, even my kids love them (maybe that's because of the chocolate). And, in case you're thinking I'm just a sucker for amazing customer service (and I am), I'll tell you that I also price shopped for the water pump replacement and found that a) Lexus was the cheapest, b) they provide a loaner vehicle, and c) it ended up being even cheaper than they quoted me because they were running some kind of special. My husband says I "drank the Lexus koolaid" and at this point I can't argue.
PS. I did not purchase my vehicle from this dealership, so I have no idea if the sales team provides the same excellent experience. It seems that most of the poor reviews are about them and, frankly, I think the process of buying any car, anywhere, is pretty painful. I will, however, give them a chance when it's time for a new Lexus just because of how lovely the service team is.
