HELP.....I have a '03 LS430. Went on a little drive yesterday, set the cruise control (with radar) to a legal 70 and 127 miles later (on flat pavement) the speedometer begain creeping higher. Because this has happened before, I wanted to see how much faster it would go. I shut it down at 92. I was on the way to my dealership for service anyway, so I asked the Service Manager and other Tech's and no one had heard of this.

Has anyone? As quiet as the Lexus is, you don't realize you speed until you look down a the speedometer or see the dreaded red lights on behind you.

Any help would be approciated. Thanks, Phil

P.S. My wife won't use it for this reason, which is too bad. One would think Lexus could figure something like this out!!!
