What 2018 Ford Fusion Energi owners say
Electrical system
The contact owns a 2018 Ford Fusion Energi. The contact stated that the hold voltage battery had decreased to 13-15 miles on a full charge when previously averaging 22-23 miles. There were no warning lights illuminated. The contact stated that the failure was related to Customer Satisfaction Program: 24N19. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and transferred the contact to the NHTSA Hotline. The failure mileage was approximately 80,000.
Ford Fusion energi battery failure. Dealership wouldn't inspect the battery and kept replacing the battery control module. The replacement part kept failing under warranty and then the dealership quoted me $20,000 for the hybrid battery. They have replaced the BCM twice and error code P0dc9 keeps appearing. The EV range drops to zero randomly or gains range while parked and not plugged in. Dealership doesn't know what's happening even after paying money for diagnostics.
Transmission & drivetrain
The car suddenly stopped accelerating while turning left into an intersection from a stoplight, heading towards to a freeway on-ramp; there was a grinding sound. I was able to move to the curb lane before anyone hit me or others behind me. The car would not go into any gears and kept rolling even when in Park. I had to put the Parking Brake on to keep it from moving back into traffic. Thanks to the kindness of strangers, I was able to get the car pushed to a safe location for a tow truck to pick up the car. At the repair facility, the assessment was an internal failure of the transmission at 114,000 miles. There was no warning or any indicator lights prior to the failure. Given Ford's history of transmission recalls and this exact issue, we strongly recommend that the 2018 Ford Fusion Energi is investigated further for a transmission recall. This was an incredibly dangerous event.
I routinely have plugged in my PHEV, enjoying the quiet electric ride. I could complete a day's commute with the electric charge. However, the battery capacity was significantly reduced at about 50K miles. At about 73K miles, within a couple miles of starting to drive, the car would decelerate and go into 'limp mode', with a top speed of 35MPH. A warning signal of a wrench would appear, indicating a power train fault. While diagnostics at the dealer didn't detect a cause, an emissions test required by the State of Colorado found an 'unstable Hybrid Battery A voltage'. I replaced the spark plugs as recommended by the dealer, but that didn't address the problem. The diagnostics and repair cost about $1000.00
