AC on my Lexus LX450 has not been running cold since last year. I received a coupon for free AC check from a local Toyota dealer so I called them to see if they would check my Lexus. They said they would check it but when I got there after driving about 20 minutes, they would not perform the AC check saying that it is Lexus and they do not have the equipment to check it. I went to Lexus next door and I was told that it is just to check whether it blows cold or not. Well...I could do that myself just by pushing the button. I thought that AC equipment is more of a universal tool. Anyways, Lexus service department seemed cleaner and not as crowded as Toyota service department. Also, to copy a non-transponder key at the lexus dealer, it would cost about $75 dollars.
