I was driving up the hill & slowed down for the speedbump. I started applying the brakes to turn right into the driveway but the car lunged forward, causing me to miss the driveway & turn into the yard. As I stepped on the brake the car continued to speed up so I screamed at my husband "james I can't stop the car!" he yanked the handbrake up but it didn't stop or slow down and the engine made a continuous high pitched racing sound. We crashed into the house, damaging it & breaking my left arm! The car was totaled. All this occurred in just a matter of seconds. Fortunately our family was in another part of the house and weren't injured.

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.

Accel Pedal Interference - Acc Floormat
Unsecured mats may interfere with accelerator pedal return to idle. A heel blocker in the floor pan provides a platform that may lift an unsecured mat into contact with the pedal. Ford introduced new pedals as a running change early in model year (MY) 2010 vehicles. Analysis of complaints received by ODI and Ford show elevated rates of pedal entrapment incidents in MY 2008 through early 2010 production vehicles. Incidents typically occur following hard pedal applications to pass slower traffic or when merging into faster traffic. Drivers allege continued high engine power after releasing the accelerator pedal and difficulty braking, including reports that the incident was controlled by shifting to neutral or turning the engine off. Drivers and service technicians reference observing evidence of mat interference or note unsecured Ford or aftermarket all weather floor mats in post-incident inspections.Based on information gathered during the Preliminary Evaluation the population being investigated has been narrowed to model years 2008 to 2010.This investigation has been upgraded to an engineering analysis on MY 2008 through early-2010 vehicles (produced through September 2009) to further assess the scope, frequency and safety consequences of the alleged defect.The VOQs associated with the opening of this Engineering Analysis are: 10479693, 10415911, 10379562, 10372674, 10345830, 10342572, 10339330, 10335336, 10334211, 10332233, 10331160, 10329659, 10327597, 10320011, 10232027, 10214131

What 2009 Mercury Milan owners say
Most recent owner complaints, unedited.
Tl* the contact owns a 2009 mercury milan. While driving 50 MPH, the vehicle began to decrease in speed when the accelerator pedal was depressed. The throttle control light illuminated during the failure. The failure recurred randomly. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure. The failure mileage was approximately 150,000.
My wife and I had returned to the car after shopping. I started the car and drove to the first stop sign. We were on city streets in the town of nashville indiana. The car was normal. I went to the next stop sign and the car also acted normal. As I approached the third stop sign and was applying the brake the car started accelerating. The loud engine noise was also noticed by my wife. I said something is wrong with the car, the engine is racing all by itself while I am trying to brake the vehicle. The vehicle was trying to move so I had to put extreme pressure on the brake pedal I looked at the engine RPM to see what was taking place and the reading was close to 3000 RPM. I held my foot very firmly on the brake pedal and took the transmission out of gear and shut the car off. I sat at the stop sign for a few moments because of the strange nature of the situation and I wasnt sure what to expect. I put the transmission into park and I restarted the car and everything acted normal. A similar sequence of events occurred periodically over the years of ownership up to the current date. The car throttle also has gone into a mode where it would not respond to the gas pedal, while driving it . It had to be shut down and restarted and it responded properly. No date or mileage to reference. This weekend I started the vehicle in the garage and the "wrench" problem light illuminated in the dash panel and the vehicle would not respond to the gas pedal. It was not drivable and had to be towed to dealership. My extended warranty expired may 2015 do to months, not milage. I am now required to pay for a new etb unit and installation.
