Car has intermittent electrical issue that causes ECUs to reboot often times disabling safety systems such as ABS, Airbags, Collision Avoidance, Adaptive Cruise Control, power steering and power brakes. Ford dealer believes that it's a short in a wiring harness. They claim this issue has been seen in several vehicles like mine. Ford was able to reproduce the problem and recommends replacement of a wiring harness ($4k). To date, I have not had an accident, but do not feel safe driving the vehicle if the airbags and other safety systems become inoperable. Yes, all of the dashboard lights come on when this issue occurs - technician states that the whole computer system gets taken down. That's very uncomfortable when you are traveling at highway speed and no longer have safety system. Steering and braking do get impacted but are not inoperable. …
This car is the second Fusion Hybrid I have. The 2015 and 2016 Hybrid titanium had the same issues. I changed one for the other in hope the problem would be gone. Almost everytime I drive in low speeds, circa 15mph up to 30mph on unleveled pavement with setts the following lights turn on: advance trac, ABS, hill assistant control. Whilst those lights are on, none of those functions works. As it happened in 2015 and still happens in my 2016. Ive complaint to Ford, but they never gave me a solution. I believe it is software problems in ABS module. But no up to date calibration files have resolved this issue. It happens frequently, so I will input the first time it happened with the older car (2015). I know that NHTSA have been investigating a similar issue with 2009 to 2011 fusions. …
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 NHTSA like to see them. …
While driving on the freeway feb 2 2016, the Ford Fusion Hybrid 2013 model, suddenly lost its ability to deliver power and propulsion. Loss of power to the vehicle resulted in loss of light to the console and to the car's propulsion system slowing it from freeway speeds of 65 MPH to what seems like 5 MPH or less, in the the evening rush hour traffic.all attempts at applying the gas pedal had failed to accelerate the vehicle, as there was no response from the power propulsion system. I was able to cruise on momentum to a soft shoulder. The car was towed off the bridge and later towed to a Ford dealership. No cause was found by the Ford technicians and Ford regional customer relations said my cause could not be helped if they could not reproduce the problem, thus I am stuck with a potential catastrophic failure that can happen at anytime during freeway commute. …
We had to have the throttle body replaced on our Ford Fusion Hybrid 2011 because the orange wrench light came up on the dash and the car shuddered and was not safe to drive. We also had to pay to have it towed. Ford's "customer satisfaction program 13n03" covers the Fusion 2011 model but explicitly does not cover the Hybrid. Apparently they do not want their Hybrid customers to be satisfied. It is very unsafe that the throttle body can fail at highway speeds, and allowing Ford to wait until it has failed to replace it, and refusing to cover the cost for Hybrid models, is unacceptable. The vehicle was in motion at low speed when it failed.
Acceleration went out. Just quit working while on interstate. Fortunately was able to coast over three lanes to shoulder. Ford dealer mechanic told me "have to reset computer. That it happens". It was second time it happened. First time was three years ago while pulling out of parking lot.
My 2010 Ford Fusion Hybrid experienced identical symptoms (twice) to those of customer satisfaction program 13n03 however the Hybrid version of the Ford Fusion is not included in the program (Ford claims it does not have the issue). I first had the issue in August 2015. I was driving on I-40 in raleigh, going up a slight hill when I noticed the car wasn't going, it was just decelerating no matter how much I pressed the gas. Very scary on a high speed interstate in the middle lane. The two wrench lights came on. I was able to 'limp home'. When we got to the Ford dealer, the wrench lights were no longer on. The dealer claimed Ford Fusion hybrids did not have the etb problem. We asked them to drive the car around, which they did, and couldn't reproduce the problem. They said there was nothing they could do unless I came in with the problem happening. …
My 2010 Fusion Hybrid began a no-start/stalling condition. It has happened six times now. First occurrence was after fueling at low speed after entering street. Second occurrence was while traveling on the highway at 55 MPH. Third occurrence was while exiting the interstate. Fourth occurrence was at low speed. Fifth occurrence was immediately after refueling while still in parking lot. And sixth occurence was also immediately after refueling just after leaving gas station at low speed. Four of the six occurrences was a failure for the internal combustion engine to start after the electric motor had already began moving the vehicle. The other two occurrences was while coasting. …
