Let me put it more clearly....I would never buy another Lexus/Toyota again!
When I bought the RX400H I specifically asked whether it could tow an RV/trailer weighing less than 3500pounds. I was told by Lexus that it could (its also in their literature) and they installed a trailer hitch for me. When I tried to get a brake controller installed (as required by California law for all trailers over 1500 pounds( Lexus told me that it would void my warrantee! It seems that they would have to cut into the computer system wiring to install it. Thus, my $52,000 Lexus cannot tow! Lexus I had to cancel my order for my trailer.
