The problem Im having is that now and then while moving down hill or slowing down, my car's rpm needle (the right odometer) will stay at 2.5-3 (around 60-70mph). I complained to my dealer who said they found nothing wrong with my car. A few months later I brought it up again and they said oh it's a common problem experiencing by IS owners!! And Lexus currently has no solution for this b/c it's a safety measure to keep the car speed in check! Anyone has the same problem and a solution for this? tyvm in advance.
