Cruise Control problems of the 2006 Mercury Montego

Tl the contact owns a 2006 Mercury Montego. While driving with the cruise control activated, the contact depressed the brake pedal to slow down, but the vehicle failed to stop. The brake pedal traveled to the floorboard when it was depressed and the vehicle felt as if the vehicle were accelerating. The contact stated that the vehicle was out of control. The contact was able to pull the vehicle over at 60-65 mph and quickly powered off the engine. While the vehicle was in neutral, the contact restarted the vehicle and it operated normally. There were no warning indicators illuminated. The vehicle was not taken to a dealer or independent mechanic for diagnostic testing or repairs. The manufacturer was not notified of the failure. The approximate failure mileage was 82,300.

I turned on road heading south and increased speed to limit of 55 mph and set cruise control. The road sloped slightly downward and the car was not requiring gas. The sensor got confused and the engine cut out leaving me suddenly without power. I was able to pull over off the road put the car in park and restart it I di not have a recurrence but am very concerned about safety. I took car into a dealer and they reset the software but told me it happens to all car manufacturer on a rare occasion and could not guarantee that it would not happen again. If I was not in the right hand lane I could have difficulty.
