The vehicle lost all power from the motor and I had to cross lanes to get to the shoulder while free wheeling. This has now happened on 3 occasions. The motor was still running but with no pulling power. Once I had switched the motor off and waited a few moments I was able to restart and the vehicle operated perfectly.

On the morning of September 10, 2013, after about a 30 minute commute to my place of work, I pulled into my work driveway, and my 2011 Mercury Mariner stalled. The engine seemed to cut off, the wrench light came on, and my vehicle rolled into the parking spot. Unsure of what had happened with my vehicle (as it had never happened before), I immediately called my local Ford dealership service department. The service manager was extremely helpful and told me it sounded like a throttle body problem, as his service department has replaced a number of these on both the Ford escapes and Mercury Mariners. On my lunch break, I drove over to the dealership and made it with no stalling out problems. The manager then told me he would drive me back to work in the vehicle to see if it would "act up." It did not "act up" while he drove me back to my place of work, but on his way back to the dealership, it stalled out on him while he was attempting a left turn. He had to turn the vehicle off for approximately 30 seconds to let it reset. He said at this point the check engine light also came on. He got it into the service department and hooked it up to the computer. The computer generated code P2111, electronic throttle body assembly. He luckily had one in stock and it was promptly replaced. I have not had any more stalling out issues with my Mariner and the issue appears to be resolved. This problem could have had deadly consequences had it stalled out at the wrong place and wrong time, particularly in an oncoming traffic situation. As the service manager mentioned to me, this has been an ongoing problem that is facing a potential recall.

My son and I were on the way home from football practice around 8:30pm and as I was turning right from a stop light the vehicle started slowing down and shaking. I pulled right over turned the car off and on. Once I got back on the road it did it a second time and so I proceeded to pull over and turn car off and on again. I was close to home and finally made it home.

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.

As I was driving my 2011 Mercury Mariner it suddenly lost the power to accelerate (engine still running). The wrench light illuminates at this time. I could not do anything to increase speed (pressing on the accelerator did nothing). The only fix is to shut down the engine and re-start. The mileage is 69, xxx. This first occurrence happened on 7/25/2013, however, the same symptoms have occurred randomly several times since that time. I explained the symptoms to my local Ford dealer service department and indications are a defective throttle body.

The vehicle has quit running suddenly without warning at highway speed two times and has quit running at low speed or at stop lights or has went to rough idle in limp home mode with no power available to avoid heavy traffic. Turning off ignition and waiting 3 minutes and restarting yields normal engine operation until it stalls again. Ford service has diagnosed defective throttle body but will not warranty the defective part even though it is covered under emissions controls.

Driving around 50 mph, all of a sudden the engine throttles down and the powertrain light comes on. The engine is still running, but no response when you press the accelerator. Had to pull over, shut off the engine, restarted the engine and it functioned normally. It happened two more times in the same trip. It has been happening intermittently. Bringing it in now because of potential road hazard.

Started vehicle in the morning for work & yellow wrench light came on, combined with "limp mode" symptoms of no throttle response. Googled & found multiple complaints for similar issues with this motor. Called local Ford dealer who said the throttle body has had 3 different part numbers which leads me to believe that this has been a know issue for a while now. Ordered the latest version of the throttle body & will have it replaced by my mechanic who said its a 1/2 hr install. I will be keeping the receipts & hopefully Ford will be kind enough to reimburse those who have had this fixed, if the issue does end up becoming a recall. What a headache.

Car seems to stall all power stays on but the car shakes and then stalls and the wrench light comes on which is a powertrain light. Took car to dealer they say there is nothing wrong with it. They reset the light. One week after bring the car to the dealer the wrench light comes back on and the car stalls this time I was going 55 miles an hour on a parkway thankfully I was able to pull over before the car stopped. Brought to dealer, nothing is wrong with the car they recommended me to leave the heat off because there could be a problem with the heat. (don't understand that) last week the car stalled again and the wrench light came on. I am currently waiting to bring it in for service. This is not good nor safe.
