Cruise Control Problems of Mercury Montego

Multiple instances of my car accelerating while in a lower rpm such as at a stop light, drive thru window and parking lots. Especially increased instances when the air conditioning is running. This also causes the car to die completely in some cases. I have to try to pull over somewhere in order to put the car in park and restart it. This issue with the acceleration is increasing in frequency lately. I can count on it to happen every single time I have the air conditioner running and sometimes when it is not. Problem has occurred hundreds of times. It is very dangerous! if I were slow to react to the acceleration, the car would definitely run over a pedestrian or hit another vehicle! local Ford dealership vehicle was purchased from said they were not aware of any issue like this occurring in other like models. Please help! last night my husband and I went through a local restaurant drive thru window and while going through the line, the engine surged 5 different times! these are not slight little rpm bumps, these are full fledged "the car thinks I am mashing down on the gas pedal to obtain speeds of like 45 mph" accelerations! today I was driving at around 35 mph with the air conditioner on and turned the cruise control on. The car died when it reached a downhill turn at the point I would have expected the cruise control to hold back the speed. Of course the power steering went out when the engine died, so I had to try and find a place to "float" into in order to turn my car off and restart it. I need this fixed very badly before my family and I are in an accident. I cannot afford to spend thousands of dollars at the dealership hoping they get the correct diagnosis nor can I afford a new car.

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.

2004 Mercury mountaineer I've experienced multiple transmission problems; a hard jerking when you place it in reverse,and rough shifting while on the highway. Dealership made multiple attempts to repair, and often said they can't duplicate the problem. Also, cruise control quits working intermittently, replaced but still a problem.
