Driving up an on ramp to an interstate highway, the car would not react to increased depression of the throttle pedal. Tool indicator warning light illuminated on the dash. I barely was able to pull off to the berm, almost rear-ended. This has happened numerous times since first occurrence on 6/11/15-6/12/15 and appears to occur only when I have the air conditioning on. Very dangerous situation!

Floor mat interference with accelerator
On May 27, 2014, Ford Motor Company submitted recall 14E-028 (Ford recall #14S07) to correct a safety-related problem with certain driver's side Ford optional all-weather floor mats sold for use in model year 2006 through 2011 model year Ford Fusion, Mercury Milan, Lincoln Zephyr, and Lincoln MKZ vehicles built at Hermosillo Assembly Plant (HAP) from November 9, 2007, to October 31 ,2010.the federal safety agency testing determined that the original accessory all-weather mat with a single retention clip (Figure 1), may interfere with accelerator pedal return to idle with the mat retained by the clip and rotated clockwise.Both the single- and double-clip (Figure 2) all-weather floor mats may interfere with the accelerator pedal return to idle when the mats are not secured by the retention clip(s).Testing showed that this can occur if the mats are moved forward from the clipped position approximately two inches into a position in which the rear edge of the mats will abut the retention clip(s) when installed singly and align with the clip(s) when stacked on another floor mat.The pedal interference incidents reviewed by the Office of Defects Investigation (ODI) include 1 crash and 9 incidents with allegations of brake friction materials smoking and/or requiring repair for heat related damage.The crash incident occurred after the parking brake was applied at speed, resulting in loss-of-control vehicle yaw event caused by lock-up of the rear tires.The spin-out resulted in a side impact collision with an oncoming vehicle in an opposing lane of traffic. For the 29 incidents with sufficient information available to make an assessment; 23 (79%) were controlled by the driver either shifting to neutral, turning the engine off, or both; 4 (14%) were ended by the driver either kicking the pedal free (2) or pulling the mat away from the pedal (2); and 2 (7%) were ended by the pedal freeing itself from the mat with no apparent driver action.None of the drivers who reacted to the incident by shifting to neutral or turning the engine off reported any difficulties with either action.The subject mats were sold by Ford and Lincoln dealers directly to customers as an optional accessory equipment item or, beginning in November 2007, the mats were also available as a factory installed accessory if ordered with a new vehicle.Ford estimates that approximately 82,579 affected driver's side all weather floor mats were sold worldwide; either over the counter through Ford dealerships or as original equipment.Owners that purchased the subject all-weather floor mats as a factory installed accessory with their new vehicle will be notified to return their all weather floor mats to their Ford or Lincoln Dealership in exchange for replacement mats.Owners of all other potentially affected vehicles will be notified that, if they have an affected Ford driver's side all weather floor mat, they should return their mats to the dealership in exchange for replacement mats.The VOQs associated with the closing of this investigation are: 10327597, 10332233, 10334211, 10335336, 10339330, 10348772 (and duplicate 10342572), 10372674, 10379562, 10415911, 10426255, 10434107, 10521053, 10554966.This investigation is hereby closed.

Most recent owner complaints, unedited.
On several occasions I will be driving my car and it begins to shake and cut off. The battery light comes on and a wrench will appear next to the parking light. I was stopped at a stop light, once the light changed I took my feet off the break and pushed on the gas. My car stalled then shook as I drove forward through the intersection my car cut off again. I had to urgently put on my flashers. I have a child and that us very dangerous. I tried starting my car again and it made the sound as if it were going to start but it didn't. The battery light came on again. I tried another time and it worked. I began driving for no more than 3 minutes and my car shut off again. I turned into a parking lot and tried to start my car. We sat there for 5 minutes. The I drove to walmart which is usually only a few minutes away. My car shut off at 4 lights on the way to walmart, and pulling into the walmart parking lot, 4 lights on the way home. This was all in one day. I am so afraid to get on the highway because my car could go out while I'm driving and someone may run into the back of my car.
Wrench and engine light came on. Vehicle would not go beyond 5 MPH. Waited and turned the car back on.,engine light stayed lit and was able to get home. I took the vehicle to autozone and received a diagnostic code p2111: throttle actuator control system, tachometer open or shorted. Called ford and they are aware but stated that they will not repair with a recall being issued.
Driving near 55 MPH on local highway and applying pressure to gas pedal to accelerate. Felt and heard a 'clunk'. Vehicle immediately lost ability to accelerate with pressure applied to gas pedal. Exited to shoulder. Noticed yellow service (wrench) indicator light was on. Put the car into park and turned off ignition. Re-started vehicle; service indicator light did not come back on. Put the car into drive and re-entered traffic flow. Did not have an incident in another 30 miles of driving. Took the vehicle to dealer for diagnosis. Dealer diagnosed problem as requiring new throttle body. Very dangerous situation.
Driving on a straight away the vehicle suddenly makes a noise as if it were shifting very hard although it was not. Immediately lost acceleration and dashboard light illuminates. Pulled vehicle to the side of the road and RPM needle bounced as car lunged but would not accelerate. Called for roadside assistance and my dealer's service department who knew based on my description a possible cause. Vehicle towed to dealer, diagnostics proved throttle body needed to be replaced. Repair made. Research proved that this is a known problem but no recall has been made. It was a very foggy morning and several multi car accidents had been reported. Had I been on busier stretch of road at the time of the break down I could have easily been killed with slowing down suddenly and without any evident cause. A recall should be issued and refunds made to those who have already experienced this failure.
I was driving down a local road at about 35 MPH. All of a sudden, without warning, I could not get my gas pedal to do anything, like it was out of gear, and the engine seemed to be sputtering. I pulled off the road, shut the car off and after a few seconds, restarted the car, it restarted and drove fine. It did the same thing again the next day. It has happened a number of times since the first time... Happening about once per day. It seems to start up ok after I shut it down, but very unsafe to be driving down the road and then have no power and have to pull off.
Tl* the contact owns a 2011 mercury milan. The contact stated that while driving approximately 55 MPH, the wrench warning symbol illuminated as the vehicle began to decelerate rapidly. The vehicle was maneuvered to the side of the road where the engine was turned off. After restarting, the vehicle was able to resume normally. The failure recurred twice. The vehicle was taken to an authorized dealer for diagnosis however, the technician was unable to detect a trouble code or duplicate the problem. The failure persisted. The manufacturer was not notified of the defect. The approximate failure mileage was 67,000.
Driving at highway speed, I lost the ability to use the throttle. The engine ran, but did not respond to the pedal. I was forced to pull the car over, in traffic, and restart the car. Once the car was restarted, I was able to accelerate.
This happened once several weeks ago with my wife operating the car and newborn in the back. I wasn't in the car so I did not witness the problem. Over the past two days I have experienced the problem first hand several times. Car stops accelerating during normal operation. The check engine light comes on, the accelerator stops working and car begins to idle erratically. The engine does not shut off. Once you coast in heavy traffic to the side of the road, you may turn the car off then restart and drive without issue for an indeterminate amount of time (once it was several weeks, once it was ten minutes). The check engine light will be off and no code will be logged into the computer. I took the car to a mechanic ten minute after an incident and the computer picked up nothing wrong with the car. With all these complaints and anecdotal evidence, by this time ford and the federal safety agency must be aware of the problem. Where is the recall?
Driving down a busy road and car went into limp mode, gas pedal not responding. Almost got rearended because the car slowed down and I had my 8 month old granddaughter in the vehicle. Took it to autozone and they ran a diagnostic said it was the electronic throttle sensor problem. Read online where this is a recurrent thing going on but no recall yet. What is it going to take someone or alot of people dying for this to be recalled? I am on disability and it better be covered under extended warranty or warranty since ford knows this is an ongoing problem.
