Yeah, I would watch out for the AC problem. Maybe it's only mine and I should get the whole system looked at to find the true root cause. It's just frustrating, when you spend all that money and you keep having problems. In Grad school, I had a 1989 Nissan Maxima(spent $2500 for it) that had over 350,000 miles on it and I never had any problems, best car ever. Then I spent over $39,000 on a LEXUS and have had all kinds of problems.....doesn't make sense. The one thing that I look at is that a car has 1 major problem area and I'm glad its only the AC and not the engine..........with this said my Lexus should run over 500,000 miles.
