I was able to replicate the first issue once, second issue happens more frequently: Braking system not grabbing on as hard as they should and abs did not activate. car also seems to lunge forward sometimes when slowing down, most noticeable when preparing to turn. Took the car to get inspected at a Ford Dealership, they claim to no be able to replicate the issue. I've also opened up a case with Ford Motor Co.

My vehicle - from a stopped position - accelerated on its own to 40 MPH (rather quickly). However, the gas pedal was not engaging (ie. Depressing). This occurred at lunchtime on 17-jun-2016. All trouble lights on the dash lit-up. The behavior continued until I shut the vehicle off at the dealer (elder ford in troy, mi). I was unable to engage the throttle at all; it was essentially 'dead', even though my vehicle was accelerating to 40 MPH and maintaining that speed. Braking response was diluted because the car was self-propelling (imagine trying to brake while also applying gas). I took it to the dealer immediately and showed them the videos that I took. I also sent the videos to them. I have been told today that they will be giving the vehicle back without any repairs because they could not replicate the problem. I have the videos in my possession, should the federal safety agency like to see them. I have had several issues over the last 1.5 years that I have owned the vehicle. I can send repair records. ....updated 12/05/16 *bf updated 6/18/18

On numerous occasions, I have experienced a momentary loss of control of my car when braking. This problem occurs when decelerating around a curve (left or right), driving downhill, or when decelerating over a bump or other area of raised pavement. These instances have occurred on city streets, at speeds under 40 MPH. When it occurs it feels as if the car is skidding, even on dry pavement. I would also describe the feeling as a surge, even though the car is braking, and should be slowing. I have also described this as a feeling that the brakes slip or stop working momentarily and then re-engage. The experience is frightening, and I am concerned that the car could surge forward while I am braking and result in a collision or injuries. I purchased the car new in 2013, and have driven the car fewer than 20,000 miles. I have taken the car in for service regularly. These surges recently have seemed longer in duration more recently. I have noted this concern to my ford dealer twice in the last 12-15 months, and asked them to check the brakes for problems. Each time, the dealership has told me that they could not replicate the surge or skidding sensation. Most recently, the service representative explained that I was probably noticing the gasoline engine kick back in after the car was in battery/electric drive. This explanation does not square with my experience. I can determine when the car shifts from battery to engine operation, and that is not the cause of these braking events. I read the complaints of a few other fusion 2013 hybrid owners with the braking system, and I wanted to add that this problem is occurring in other vehicles. This is not a safe condition. I will again be taking my car in for service, and asking for ford to investigate this problem.

Twice I have turned right into my driveway and my car has surged forwarded as if hit from behind or the brakes failed. I am obviously at a low speed and the road slopes down slightly. My drive is gravel. It probably surged a good car length before the brakes engaged, yet my foot was on the brakes the entire time. It was scary as hell. The first time I thought I had been hit from behind by another car. The dealer looked at it today and found no issues. I'm not happy with this waiting to happen again as I have no idea what sequence of events caused it before. The first time was about a month and a half ago and the other time was one week ago.

Beginning about january 2015, and occurring a total of about six times so far, my wife's 2013 fusion hybrid (currently with 25,500 miles) experienced what feels like a power surge. (I experienced this once in this vehicle; the remainder when my wife was driving.) it is possible that this is related to the regenerative braking system at least in part, as I have seen others describe it as a feeling of hitting an ice patch. The general conditions would include: a) foot on brake; b) decelerating; c) presumably in EV mode [though not necessarily]; d) beginning a left turn [but we believe this is incidental]; e) warm engine; f) less than 30 MPH. On october 1, 2015, a new condition caused the feeling of unintended acceleration, as my wife was on a side street near our home when she was approaching a stop sign and felt the power surge, which she states was many times worse than any other instance of this event that she ever experienced. Conditions this time were the same as above but moving straight and less than 25 MPH. We took the vehicle to the local ford dealership the evening of the last incident. Of course they found no codes and no evidence of anything wrong. I also contacted the ford customer relationship center while it was in the shop to document that we had this problem. They seemed helpful however, unless ford motor company and their engineering community acknowledge a problem and do something to address it, it will forever be a ghost in the machine, with the blame and doubt falling on the vehicle owners, not unlike toyota's well documented, fatal and shameful unintended acceleration cases. I am concerned about our safety while driving the vehicle. I hope that no one gets hurt or killed while this problem exists and urge ford motor company to get to the root of the issue that myself and other owners are fearfully experiencing.

My wife and I were entering a parking lot with the ford fusion hybrid and slowed down, then started to slowly accelerate, the ffh wouldn't go forward normally and sort of stalled. My high voltage battery state was low (1/8 charged) and the car had about 3/4 tank of gas. It began with a series of surges that were caused by the car not knowing which propulsion source to use. It tried the gas engine, surged forward a few feet then tried to switch back to the electric motor, etc, - this happened about 6 times before I could get it to surge out of the driveway and park safely. I put the car in park and pushed the gas pedal trying to force the gas engine to take over and that caused an engine stutter and again the car tried each source of power - I turned the key off. Upon a restart it was as if nothing was wrong, it ran normally so I ran a ford vehicle health report (vhr) while sitting in the car idling, that report is sent to my ford owner's account, I did this to try and catch any errant dtc's (trouble codes). After that I restarted the car into the engineering test mode to show my digital dash display's internal readings, no dtc's were present there either. We finished our business and drove the 20 miles home without any problems, all normal. That was the first time this has happened and is a very unsafe situation.

Car was being driven down steep driveway by my 88-year-old father. He says car accelerated without him giving it gas. He is backed up by black box, which says no pressure on accelerator. He also says brakes didn't work, which is not backed up by black box, which says no pressure on brake either. Car left driveway, hit tree, and ended up approx 200 yards down steep hill. Black box says rolling occurred. Only passenger side curtain airbags deployed. No front airbags deployed and no driver side curtain airbags deployed. Injuries to both him and his companion resulted in hospitalization to both.

On may 9, 2013 at approximately 8 am, shortly after entering a two lane state highway driving my 2010 ford fusion hybrid, I removed my foot from the accelerator and brake my car to stop at a traffic light 6 feet behind a stopped 2007 mercury mariner. While stopped for a few seconds, I removed my foot from the brake pedal and the car suddenly accelerated traveling approximately 6 feet, colliding into the rear bumper of the mariner. My fusion bumper slid under the mariner bumper crashing the grill and causing substantial damage (approximately $5000) to the front end and hood of my fusion. I am uncertain as to why the car accelerated. I had not had a similar experience during more than 50,000 miles of driving. It may be that the combination of the gas engine idle and/or the start of the electric motor may have caused the car to accelerate to a speed which was sufficient to cause the bumper to slide under the mariner's bumper. I have questions relative other similar events for fusion hybrids and as to why the bumper did not function as required by regulations to protect the car from damage when traveling at speeds of up to 5 MPH. I have made inquiry of ford relative to the safety issues , however they were not responsive in a phone interview, which was quickly terminated informing me that the legal department would contact me. I received a letter from ford's legal department declining to compensate me, even though the compensation issue was never mentioned in my inquiry, and warning of the problems of litigation. I do not contemplate litigation. Have there been similar reports filed with your agency?
