general problems of the 2003 Acura TL

As I was accellerating onto the highway, the car continued to accellerate. At 89mph I hit the brakes hard to see if I could slow down. Would not happen. Put the transmission into neutral and shut off the engine and braked to the side of the road. When the dealer examined the throttle body they found the plastic cam for the cruise control had broken and the cable for the cruise had jammed the throttle wide open. When asked if that part was replaceable I was informed the whole throttle body would have to be replaced at ~$500. The alternative was to remove the cruise cable and tie it up away from the throttle body. Since the dealer told me this was the second one they have had with this problem, it was rare. Oops if this would have happened in town I would have hit several cars before getting it shut down. The throttle cam is made of metal where the cruise cam is plastic and both are on the same butterfly shaft. Just to save a few cents makes for a very hair raising ride.
