We live in Corpus Christi and have taken our RX330 to Houston twice since purchasing the vehicle. Each time, with the cruise control set at 70 mph, we have been cited for going +10 over the limit. The first time, I thought it might have been that I put my foot on the pedal, or wasn't paying attention, or, yes, we were on a hill and it surged suddenly to get up to 70. The second time, however, we had just come over a hill and started down. The cruise was set, and the speedometer said 70. Ideas? or should we take it to the dealer? Needless to say, it's confined to city driving until it's diagnosed. Thanks for any help !!
