I was on my way home from work(approx 12 miles) and decided I'd try out the cruise control in my newly acquired 2000 Mountaineer 302 awd. The first part of the commute is what I would consider harmless and a very safe stretch to test out this feature so I press the cruise button to set my speed at the posted speed limit of 55mph. All was well until I approached a sharp hair pin curve about 4 miles into the trip. I gently started to apply the brake to cancel the cruise but the vehicle didn't respond to my attempt. In a state of panic, I firmly apply the brake to reduce speed and was only able to drop approximately 6-7 mph. Still well above the advised limit for that particular curve. After making it though the curve, the Mountaineer transmission down shifted and I was off to the races. I panicked and in doing so, failed to process and think clearly. My instinct was to keep pounding on the brakes in hope that the cruise cable with break or pop free. At 70mph my brakes were useless. It accelerated just past 80mph and finally right before my turn off onto the road that I live, my head cleared and I turned the ignition key to the off position and was able to coast into my neighborhood. As I exited the vehicle, every ounce of coolant was being shot out of the radiator and all four brake rotors were glowing cherry red. I was scared the thing was going to catch fire. Like incident report prior to mine, my cruise cable retainer had malfunctioned and was no longer anchored to its usual position. Ford has a major flaw in the way this system was designed and needs to take action so someone doesn't get killed. Hands down, the absolute scariest situation I've ever experienced.
