Periodically when apply brake, no engagement, as if I hit a patch of ice, then the break engages.

- River Forest, IL, USA

The contact owns a 2013 Ford Fusion hybrid. While operating the vehicle, the advancetrak, power train, up hill assistance, and stop driving warning indicators illuminated. After turning the vehicle off and back on, it accelerated to 35 mph on its own and would not exceed that speed. During the failure, the brakes did not operate properly and failed to immediately stop the vehicle. The vehicle was towed to Ford autonation torrance(3111 pacific coast hwy, torrance, ca) where it was diagnosed that the aftermarket security system caused the failures. After removing the security system from the vehicle, the failures continued. The manufacturer was not notified of the failures. The failure mileage was 35,000.

While driving 65mph on a back road leaving harris co. My car started to speed up without me pressing the paddle and when I pushed the brakes I had to push it several times before it would work and slow down the car. It pretty much made us jerk forward when the brakes started to work. I have never had this happen until Wednesday Oct. 24, 2018 and don't know who to contact. I had my daughter and niece in the car coming from my son football game. That was scary and I hope it don't happen again.

During breaking at approx. 15-20mph the break pedal became very soft and lost most (90%) of the breaking power. The dash breaking and stability control warning lights flashed. The electronic emergency break engaged and would not disengage. Car had to be towed to local dealership.

Car lurches forward when braking as if the regenerative braking shuts off momentarily and turns back on. Happens when going over some bumps and during turns. It is most noticeable when making left turns in a turn around in a separated highway with a median, where you need to slow down quickly, making a left turn and braking at the same time, so less than maybe 30 mph. It is frightening when it happens, and I'm afraid I will run into someone in front of me. I've taken it to the dealer Feb 4, 2016. The dealer could not reproduce. I don't believe they put much time into finding it as the mileage in and out are the same. The dealership did a PCM update but that did not fix the problem. I read a complaint from another owner and it describes this problem which prompted me to file my own complaint. This is a daily occurrence. It has been going on for at least a year. Does not seem to be getting worse.

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.

We own a 2013 Fusion hybrid and have experienced a very scary feeling as the vehicle accelerates for few seconds before it comes to a stop, after applying the break. For that period of time from putting on the breaks to the vehicle stopping, it feels like we have lost control over the car. We have been observing this at least twice a week on an average. Left the vehicle with the dealer for a week last year, and they claim they could not observe the same thing after driving for miles. It is hard to know in what scenario this thing occurs, but is definitely a scary experience.my husband got into an accident a month ago where two cars in front of him got involved. He was at a good distance and he hit breaks, but next thing he knows is the air bags are blown and his Fusion had a good amount of damage in the front. He does not know what happened in that moment, but it makes me think and hope that it was not the same scenario where the vehicle accelerated and he lost control over it. It is unfortunate for me to say this, but I work for Ford through one of the vendor companies and still can't help with this situation. We did what we could by talking to the customer service and the dealer, but could not get any answers. I am hoping that more people who are facing this issue will write here and they would investigate this issue. It is a sad experience, and have to live with this scary thought and hoping no one gets hurt.

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.

Car surges while turning as if it hit a patch of ice, regardless of speed, but only when regenerative brakes are applied. Happens in both directions and is consistently reproduced, more noticeable with higher speeds. Regenerative braking is also inconsistent, at times it will not properly slow the car down. As more pressure is applied, the car is not slowing as expected, and has gone into intersections as the transition from regen braking to hydraulics does not occur quick enough, and feels like brakes are fading. Dealer and Ford has looked at the car and said no trouble codes, nothing wrong with the car. This could lead to an accident as it is never known if the car will slow down using the regenerative brakes or not until they are applied. I do not feel Ford is taking this serious enough, and refuses to spend time to diagnose.

While driving, my "check engine" warning light, "low oil pressure" warning light, and the "stop safely now" warning came up on my dash. I lost all power steering and breaks, and the engine cut out. I struggled to stop the car, but eventually it stopped moving. I turned off the car and turned it back on, receiving no further errors. I called the dealership to find out that there's nothing they can do since the car is no longer in an "error state".

I was traveling 55 miles per hour in the hybrid mode, when I needed to slow down very suddenly for much slower traffic. Applying my brakes firmly, they locked up, causing my car to swerve between three lanes while the backend fish tailed back and forth. I could hear the tires skidding on the pavement and my steering was very difficult to control.
