FORD PRODUCTS CANNOT BE TRUSTED AND ARE A TOTAL SCAM

Ford has intentionally crippled the operation of the electronic vehicle (EV) mode based on battery age alone in their fusion hybrid. Battery tests fine, but they have incorporated instructions in the software which cripple the operation of the EV mode dropping mileage from 42 mpg to 22 mpg and significantly negatively impacting the vehicle operation (CA 172-22628-T2W1F5) by forcing the engine to run all the time..

When the Ford Dealer asked Ford Engineering for assistance with the problem the vehicle was experiencing, they initially had no idea what was causing the issues. After over 3 months, Ford determined that my 2010 Ford Fusion Hybrid with 74,000 miles is operating as designed/planned no longer operates as a viable EV vehicle! So like the Apple iPhone, they have intentionally embedded commands in the cars Program Control Module (PCM) that disables the vehicle EV mode and makes it unsafe to drive. By hacking the PCM software and entering a battery date that is 5 years old or less (with the assistance of Ford Engineering), the vehicle's performance is restored to its original condition. However, the Dealer refuses to make this change permanent due to potential liability concerns!

Dealer says it is Ford's problem and Ford says it is dealer problem! No one is willing to take any ownership of the issue even though the problem got worse after the new PCM was installed. Ford has said that there is nothing more they can do and have closed the cases opened by the Ford Dealer and myself. I have been told that my only option is to seek legal recourse. The Koon's Service Manager told me that he is not able to share or say anything negative about the Ford Motor Company of their products!

I am very angry. I spent about $7,000 more to purchase a car that had an unknown to the consumer a built-in planned obsolescence based solely on the age of the main battery (from date of manufacture) irrespective of fact that all other parts test fully functional!!!!!! A representative from Ford Customer relations told me that I should not be driving a car that old anyway!!!!!!!!

If you own a Ford Hybrid, you need to be aware of this time bomb Ford has in store for you. I will never buy another Ford Product and don't know why anyone would given the situation that exist.

Ford dealership is unable to diagnose, let alone repair the problem that prevents the electric motor from operating the car.

  • CVT transmission
  • 86,650 miles

Well, after 8 years of hybrid operation as designed, my car has stopped functioning correctly as a hybrid vehicle. I told Ford that a couple of times the car worked perfectly upon starting, then next time started would not work in hybrid mode. Given age of vehicle, Ford recommended that hybrid batteries be 'reconfigured". Only half the batteries were reconfigured the first time in the shop. This didn't actually fix the problem although the car would switch to EV upon coming to stop. Hybrid batteries have always indicated that they are full. Then car engine would not even stop at red light.

I brought the car back to the shop where it stayed for two weeks while mechanics communicated with Ford "Hotline".. Recommendation was to reconfigure all batteries at warm ambient temperature....this was done and all cells were within .07 volts of each other. Car was reprogrammed for new battery configuration as before...this didn't fix the problem either. Ford recommended checking the regular 12V car battery and found it have one bad cell (even though battery purchased from Ford and only two years old). Car battery was replaced and hybrid batteries again reconfigured as per ford protocols. According to mechanic the reprogramming of the car to the reconfigured hybrid batteries keeps "timing out".

Ford then recommended replacing the battery energy control module. This was done, battery reconfiguration, car reprogramming repeated. Still car does not work in full EV mode under 45 MPH as it was designed although engine does turn off at stop, but release brake and engine immediately starts. Ford hotline now says that battery control module should not have been replaced, that the car is working at "optimal performance" for its age (9 years; 87K miles) and cannot be fixed and return it to customer. Don't see myself buying another Ford vehicle.

Update from Feb 18, 2019: Well, Ford's "repair" lasted only two days; Now the car does not even turn off at a red light!!! Ford service says they don't want to see the car back in their shop as they still maintain that the car is working at "optimal performance" given its age and ambient temperature.....which hastn't been that cold here in New Jersey.
