I was driving my vehicle at a low rate of speed on a city street on 10/16/15 and as I turned a corner, about to pull into a driveway, there was a complete loss of power steering ! the vehicle was very difficult to control and it took all my strength in both arms to complete the turn and pull into the driveway safely. The vehicle was towed to crest Ford dealership in flat rock, mi and the diagnostic code they detected indicates they need to replace the entire steering column and is supposed to be covered under Ford's recall 14S05. Dave in their service department took what he described as "the first step" by sending an email to request that this repair service be performed under the recall. It was denied by Ford because a different code, also covered by this recall, was addressed by Liberty Ford in brunswick oh on 5/11/15 (at which point they updated the power steering control module). I contact Ford customer service myself on 10/19/15 and was told that the "program had been closed" on my vehicle because service under the recall has already been performed. It's ridiculous that they aren't now going to service the additional problem that has occurred and is supposed to be covered by this recall!

I was driving 65 mph on the freeway when my engine stalled. I costed to the side, turned off my car, and restarted the engine. My SUV ran normal for the next 5 miles before the same problem occurred. This time I was at a light and was able to stop and restart the engine. The engine started, but was running slow and the gas pedal was non responsive. I coasted to a side street where I turned off the engine. Once I tried to restart the engine, it took about four times longer to start than normal. I put the SUV in drive and it jumped slowly at a costing past with every fluctuation of the engine RPM pace. I would have had an accident if this would have occurred on my way home from work in traffic. Thankfully it was during the day with little traffic. The dealership seems to think it is a problem with an electronic throttle body. I will be trading my Mariner in for a different car because I do not feel safe driving the SUV. I am fortunate that my SUV stalling did not cause an accident. However, I'm sure there are others who are less fortunate. Please help by forcing Ford to recall these vehicles and replace this part before this issue causes a fatal accident. Thank you.

On June 6th, is as going approximately 35 miles per hour when the car went into idle mode. I pulled to the side of the road and the car restarted after cranking it several times. The problem continued but only when traveling at lower speeds. I made point of traveling the back roads when possible. On the 13th of August, I was on the freeway when it happened. I was only able to travel a few 100 feet and it continued this way till I got home going the back roads again. The car has sat there ever since. My husband has been out of town for three months and returned that night. He had the codes checked and they read P2111 and P2112. He did research the problem and came up with many complaints of defective throttle body.

Needs a new electric throttle due to the same issues reported in previous complaints. Exact issue referenced below. "in two recent complaints to nccc, drivers reported intermittent vehicle stalls and surges as they enter traffic from a stopped position or while driving at highway speeds. As the problem was initially intermittent, the drivers continued to operate their vehicles in this condition, eventually progressing to the point of keeping one foot on the brake while stopped and the other on the gas pedal to keep the vehicle running."

Vehicle traveling at 70 mph on interstate engine quit and loss of steering and control. Pulled over re started happened again. And engine light went on. Re started drove to dealer later and discovered after $100 diagnostic that the throttle body was not working properly. Happened when mileage was between 38-39000. They wanted me to pay over $590 to replace their defective part at Ford dealership they refused to put it under any warranty or recall. I did not have it fixed. It is a danger to allow this matter not to be recalled as it has happened thousands of times in many Ford vehicles.

If this is the wrong forum for this issue, please let me know. We purchased a 2008 Mercury Mariner new, so the car is less than 3 years old and while garage kept the vehicle mileage exceeds the new car warranty. We took the car back to the dealership and were changed $118 to diagnose a problem with the backup system/sensors and were informed that the sensors were fine but the electronic device which calculates distance was bad, to replace an additional $500. Why have backup system/sensors on a vehicle if the life of the electronics is so short if this safety device is intended to provide benefit, ours is now permanently disabled. I don't understand why "safety" equipment is not covered for longer periods of time. Regards,
