Was driving down country road and all of a sudden felt then engine what I thought was kick out of gear. Had no acceleration at all. Pulled off road and the vehicle was running in a rough idle, but still could not give it gas. Once placed in park the idle leveled out and still no acceleration. The wrench symbol was on. I stopped the engine and waited 10 minutes then restarted engine and everything was ok. For about 3 months. I took into the Ford dealer only to be told there was no code and they could do nothing without it. Problem has gotten steadily worst. And now it is at point where wife can not drive her car! I am driving it and finally yesterday the engine light came on. I ran it to autozone where they confirmed the dreaded P2112 code. I took it to the Ford dealer today figuring alright less than 5 years old and 42,000 miles I would finally get it fixed. No go! although for $106 they did confirm what autozone already told me that the throttle-body was shot and would cost another $430 to fix.I promptly called Ford customer care line and was told that they would contact the service manager at my Ford dealership to work out a payment plan for me to get it fixed still at my cost. This is crazy that I payed over 26,000 for a vehicle that I still owe 11,000 on and under 5 years old with 42,000 miles and this is my 3rd major problem with it.. have already had the engine pulled apart once to be fixed and one of the drive shafts had to be fully replaced. This is unfortunate but will be the last Ford I ever own!!!

Car stalls and/or otherwise looses motive power at all speeds (start-up, low speeds, as well as, mid and high speeds) causing dangerous situations on the highways. The part (electronic throttle body) needed for this repair was originally back-ordered 7-8-2013 with expected delivery date of 8-7-2013. Now the expected fulfillment date is 9-23-2013. This is an incredibly longtime to wait to have a car fixed. Can anything be done to expedite this unrealistic time line. How many of these failures do they have" is a recall warranted"

2009 Mercury Mariner engine stalls, surges then no acceleration. Coast to side of road, while trying to not get rear-ended. Engine still runs, is extremely rough. After turning the ignition off, then wait and restart, runs okay. This has happened on many occasions in past month and half. I contacted Ford dealer and service guy says it is most likely the throttle body starting @ $500 repair not covered under the warranty. Happens at any speed. From start or just while driving. First incident 5-31-2013.

Car stalls continuously.

Driving along at 40 mph and the vehicle started slowing down. Giving it more gas had no impact. I noticed a wrench light illuminated on dash. After sitting for a few minutes the vehicle was restarted and ran fine. This happened again a few weeks later so we brought it to our repair shop. After some research it appeared that others had the same issue and that replacing the throttle body may be the issue. The part was replaced and we didn't have the issue for months until it happened again. It's been a total of 5 times it has happened. Really worried that this will happen on the highway where there is higher risk of an accident. Not sure what to do next. Sure seems like many others have this issue. Does Ford have a solution for this?? if they do they should issue a recall before someone is hurt badly.

While driving, my SUV completely stalled and stopped running. I turned the vehicle off and restarted it and it then it went. This happened continuously. I called the dealer where I purchased the car, benson Lincoln Mercury, in pittsburgh, and the service advisor told me that he didn't know what it could be making it stop running. My husband works in the automotive industry and it happened when he was driving the car and the "check engine" light came on. He put it on the computer and received the code, P-2111 "throttle actuator system stuck open." It seems that many other people are having this issue too. In April, the dealership put a computer "update" in my car. Could this have an impact. I should not have to pay for a part for my car, when this is obviously a defect of which the manufacturer is aware.

When being aggressive with the accelerator the engine stalls and the accelerator stops working forcing the driver to pull off of the road. When bring the car to a stop it jerks forward until it is put into park, still the accelerator does not work no matter how pushed. After turning it off start up takes longer than usual and either the little wrench or the engine symbol appears. After taking it to a mechanic it is diagnosed that is has a bad electronic throttle and it will have to be replace. Prior to this there has not had an accident, instance or work done that would cause this.

I was leaving work and driving down a road at about 50mph when all of a sudden my car jumped and I then was coming up to a red light so I was braking and behind a car. At the red light I was a few inches from hitting the car because my car kept jumping forward. I then got scared and turned my car off and back on and it was driving fine. Then all of a sudden it did the same thing and I couldn't accelerate I would press on the gas and my car was just shaking and losing speed and wouldn't move. Thankfully I didn't drive the highway home that day.

This is the fourth time since purchasing the car at carmax in October 2012 that the car has "shut off" without warning at low speed when close to parking or driving slow--without rhyme nor reason--I had it diagnosed at carmax to no avail, then Cherokee Ford to no avail (where I purchased a new battery), then at christian brothers auto where they replaced the spark plugs and coil.( I have an extended warranty so my cost was 200dollars) the problem continues. I have done research and see the throttle body is most likely the culprit and a safety alert is on the web from consumer report and Ford forum and North Carolina safety board---I am having the trottle body replaced at my expense--my daughter drives this vehicle and I want it safe! apparently this involves this model 2009-2012.

Update to 01/30/13 complaint. I purchased car on 10/22/12 with 58,398 miles from a dealer. I started having issues late December 2012. I was having problem with car jerking into gear or being sluggish when accelerating. I took car to dealer on 01/29/13. Researched carfax information and found out that on 01/05/10 - transmission flushed and stated as replaced. 18,588 miles. 08/09/10 - transmission was removed to replace cooler. 28,372 miles. On 01/29/13 mechanic advised that transmission was leaking badly and that "press regulator valve sticking". 01/30/13 - transmission valve body replaced. 63,356 miles. 6 weeks after valve body replaced car started jerking again. Took car to dealer on 03/18/13...dealer suggested replacement of transmission, but extended warranty company said no...would only pay for transmission rebuild. 65,951 miles. This entailed day and half of dealer/warranty company haggling over repairs. Mechanic began work on 03/21/13 and found lots of melted plastic that he had to remove. Transmission work completed on 03/23/13 but repair revealed starter problem. Dealer currently waiting on approval from warranty company to repair starter. Mechanic advised if starter not repaired will cause fly wheel problem. Mechanic is annoyed that transmission is having problems so soon after 2010 "repairs" and that warranty company refused to replace transmission.

While entering interstate highway, engine balked like bad gas. After two or three tankfuls and the vehicle dying in traffic, I left it with my dealer to find the problem. After a week, the vehicle had not died for them so I brought it home, only to continue with the same dying and hesitating when accelerated. A month or so later the dealer kept it again for about 5 days and it still did okay for them. They have no idea what the "problem" is. We have parked the car in our garage because several times we have narrowly escaped being rear-ended, when turning corners, crossing railroad tracks, etc. I contacted Ford Motor Co. In Michigan and they do not "have this problem with other vehicles" and don't seem to know what I'm talking about. Mechanics in two other garages have driven the vehicle and have not located the problem. Help!!

After coming to a stop at a light or stop sign, as I accelerate my car jumps/jerks as if it's straining to switch to next gear. Generally happens when accelerating between 10-40 miles. When it initially started it would happen 1-2 times a week. Now it happens every day. I have an appointment schedule to have dealer look at vehicle.
