2014 Ford Fusion engine problems

“Following the execution of mandatory Emissions Recall 25E01 (PCM Reprogramming) by a Ford dealership, my vehicle suffered a severe network software corruption causing unintended engine acceleration and a sticking throttle. The engine holds its RPMs and continues holding until I release my foot off the gas pedal and when the car is placed in reverse the car puts/jerks. Additionally, the electronic trunk latch fires spontaneously , causing the trunk lid to fly open while in motion and/or while the car is off and locked along with other electrical issues. When the trunk opens after I’ve locked and secured my car, it has caused my car battery to drain overnight and required multiple jumps before operating again, I have since received a new battery as a resort of this electrical disturbance.The dealership has confirmed drivetrain issues but refuses an immediate remedy. This is forcing me to operate a criminally non-compliant and unsafe vehicle that I notified the dealership immediately and same day in June 2026. More problems continuously presents itself.”

“The car is suffering random shutdown and intermittent times. The battery is no longer holding a charge and when it shuts down this places me at extreme risk. Ford is unable to fix it so this is no longer happening without replacing the High Voltage battery - battery from ford alone is 11k. I cannot be the only one who is dealing with this car doing this.”

“coolant leaking into engine * sudden engine failure risk * overheating * loss of power * expensive engine replacement from known defect 2014 Ford Fusion EcoBoost is losing coolant internally into the engine. Ford dealership diagnosed coolant intrusion requiring full engine replacement costing approximately $14,000. This appears to be a known defect affecting many Ford EcoBoost vehicles. Vehicle experiences coolant loss and risk of engine failure.”

“Transmission randomly stopped driving at highway speeds rpm spiked and no movement was in fast lane at 75 mph. Transmission is toast now in for 4-6 thousand dollars to replace also ford did the recall on the emissions reprogram a few months before this issue then tells me it needs a catalytic converter another costly repair car is unsafe. I’m thankful I was driving and not a family with kids.”

“My 2014 Ford Fusion caught fire on January 19, 2026, while parked and stationary inside my residential garage. The vehicle could not be shifted out of park during the incident. Emergency services responded, and an official fire department report was generated. I had owned the vehicle for less than one year and performed no mechanical, electrical, or aftermarket modifications. The vehicle had undergone parking brake service at a licensed dealer prior to delivery, with no work performed after I took possession.”

“The transmission failed completely. The vehicle will not engage or shift properly and cannot be driven. The failed transmission is still installed in the vehicle and available for inspection upon request.”
