Welcome to the forum damon. Not surprised the dice wouldn't work for you. Your car's 7 model years old, and I think they're designed for newer cars ... say, no older than 4 or 5 years. Since this is the hybrid forum that you've drilled down into, the oldest model you'd likely find being talked about here, would be no older than 3 model years ('06 - 07' - 08' ... btw, anyone here even own an '08 yet?). Kinda curious though, what the web site info was, that you feel was misinformation. Maybe a link would be helpful?
Please see my post here http://us.lexusownersclub.com/forums/index...showtopic=41153 I just received the vehicle, transitioned from a 2007 ES350 Ultra lux.
