On numerous occasions, I have experienced a momentary loss of control of my car when braking. The car accelerates momentarily after the brakes engage and I have taken my foot off of the accelerator. This problem occurs when decelerating around a curve, driving downhill, or when decelerating over a bump or other area of raised pavement like my driveway. These instances have occurred on city streets, at speeds under 40 mph. When it occurs it feels as if the car is accelerating. 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. The car currently has 26,000 miles and 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 and asked them to check the brakes for problems. The dealership has told me that they could not replicate the surge or skidding sensation. This is not a safe condition.

While braking using light to medium pressure (and, thus, while the car is using regenerative braking), if I hit a pothole or bump just right, the car will surge forward as if the accelerator was pushed. (and, of course it wasn't.) the problem is relatively intermittent, but that doesn't mean it is nonexistent. Quite the opposite; it can be recreated as long as the conditions are correct (as described above). Even when you recreate the exact conditions, it is still intermittent (but, again, that doesn't mean nonexistent). Ford has looked at the problem repeatedly and deemed it "unable to recreate." This is a falsehood; the problem was recreated once with a dealer driving the car. Also, Ford gave me a data recorder unit and, using that, I was able to recreate the problem while the recorder ran. When they retrieved the data, Ford claimed the car "performed as expected." Ford refused to explain whether that meant the car did not surge or whether it appeared to surge, but the surge appeared to be called for. Ford refused to release the raw "flight recorder" data to me. Ford refuses to further address this problem. Out-of-control surging is a dangerous and serious problem and this problem remains unresolved. I have document every step of the way as I have attempted to resolve this. I attach below a letter I wrote a year ago that both details what I had been through and the problem itself. I would be happy to provide much more. The date I put below is only an approximation. I'm not sure exactly when it started, but it has been going on for years.

Wife was driving the car to work approaching a stop sign to a very busy highway. She went to apply the brake when she discovered that the brakes had completely failed, steering control had been lost and the parking brake had been disabled as well. Basically all means of bringing the vehicle to a controlled stop had failed at the same time. Being unable to bring the car to a stop it carried her out in the highway were luckily the large truck coming down the road was paying attention and managed to swerve around her. She was able to get the car to come to an eventual stop at which time she call me and I came to look at it. I was able to confirm that the car had no brakes, power steering was lost and that the parking break was in failure as well. We had the car towed to billy howell Ford where they initially told us that they suspected that the wiring harness had gone to ground but found out later that the ABS module failed which has controls into the steering and parking brake system which is why those failed as well. I opened a case with Ford given the near catastrophic nature of the failure and asked them what are options were to trade the car in because I didn't want anyone in my family going back into the vehicle. I was told by Ford that the car doesn't qualify for buy back since it is a 2013 and that I did not qualify for any programs. Explained to Ford that I was not looking for a buy back but just for them to work with the dealer to allow me to trade it in for what I owe which is not far from the trade in value. The dealer told me that there is not an active recall on the failure we experienced so we would have to pay approximately $2,000 to have it repaired as well.

Initial failure of parking break switch warning light (and switch itself) follow by wire harness failure under dash due to wires rubbing against exposed steel dash frame causing unknown additional issues, including activation of dashboard check engine light. Failures happened over time as wiring became frayed and finally caused a series of short circuits. The wiring harness failure was reported to Ford customer service - case number cas-10375276-L2-W7-J7. No action was taken other than a follow-up email from the dealer's service manager suggesting I hold on to the paperwork in the event of a recall. Note that the mechanic informed the service department that "I've seen this before". the car has about 62,200 miles on it and is only 3 years old. Given the computerized nature of this car, a computer wire harness failure is clearly a safety hazard worth investigation. My guess is that there are several possible simple fixes, including re-routing the wire harness, lining the steel frame with a rubber coating and similar appropriate steps that could be taken.

The regenerative braking will cut out under specific circumstances and the car will feel like it is lurching forward instead of slowing down. The situation is: Braking using only regen brakes, no friction brakes; steady pedal pressure; going 15-20 mph; turning the steering wheel at least 90 degrees left or right; driving on smooth pavement. Data I have logged from the sobdmc indicates that the traction motor briefly reduces its negative torque which causes the car to surge forward. In one instance that I logged the negative torque shows around 48 ft-lbs and then suddenly drops to about 8 ft-lbs. The traction motor then gradually increases torque back to the appropriate level. In another instance the negative torque suddenly went from about 28 ft-lbs to 8 ft-lbs. The drop in torque occurs in 1/10 of one second per my logged data. It takes about 2.5-3.0 seconds for the traction motor to return to the appropriate level of negative torque to stop the vehicle. This behavior began occurring right after our vehicle was serviced by a local Ford dealership. The work done by the Ford dealership included replacing the 12V battery & 3 recalls: 14S21, 15E03 & 15S14. I believe that this service is responsible for these problems, as this issue was not present before our car went to the dealership.
