“Coolant Intrusion. Started with thick white exhaust when starting up in morning. Turned into acceleration lags, car shutting engine off when parked, and exhaust smell coming inside of car. 2014-2019 models have a recall for cracked engine block allowing cooling to leak inside, but 2020 models do not although there is an increased problem with this year and model of car.”
“A failed transmission cooling line caused the transmission fluid to leak. At no point did the vehicle display a check engine light, transmission warning, or any other indication that there was a problem. According to the Ford dealership, the transmission fluid had been leaking for some time. Because the transmission pan is wrapped in a fabric-like insulating material, the leaking fluid was absorbed rather than dripping onto the ground, making the leak virtually impossible for an owner to detect during normal use. The dealership also advised that this condition could have created a potential fire hazard within the engine compartment. The vehicle has only approximately 40,000 miles, making this type of catastrophic transmission failure especially concerning for a relatively low-mileage vehicle. The first and only symptom occurred when I started the vehicle one day. It hesitated, struggled to shift out of first gear, and drove abnormally. I immediately drove it to the Ford dealership, where it was diagnosed with a complete transmission failure. The vehicle is currently at the dealership, and I have been presented with an estimated repair cost of approximately…”
“I’ve learned a while ago that the vehicle doesn’t have a working horn, I’ve replaced the fuse at least five times and it’s still not working. Yes the car was sold to me this way. Also I’ve been getting this warning to my ford app: “The Blind Spot Information System (BLIS)/Cross Traffic Alert (CTA) has detected a fault and may not function. What Should I Do? If either BLIND SPOT NOT AVAILABLE/SENSOR BLOCKED SEE MANUAL or CROSS TRAFFIC NOT AVAILABLE/SENSOR BLOCKED SEE MANUAL is in the information display, the system may not function. Check the exterior vehicle sensors for damage or debris covering them (see Owner's Manual for sensor locations). If the problem persists, please have the system checked by an authorized dealer.” For the last month my car has become hard to drive as if there’s a power steering issue.”
“I have had this car for 6 years and the transmission has gone out on top of the purge valve, I have seen many people have the same issues with this model and year of this car. THIS NEEDS TO BE ADRESSED. I also see that there is a lawsuit against this issue with the transmission model 6F35”
“2020 Ford Fusion 1.5L EcoBoost engine completely failed. Ford dealership diagnosed need for complete engine and turbo replacement at $13,475. Believed to be related to known EcoBoost coolant intrusion defect.”
“Coolant problems and cylinder damage on engine due to coolant intrusion. Ford has not issued a recall on this well known problem and issue on ALL Ford Fusion Models. Several complaints have been made by many Ford Fusion owners for putting drivers and vehicle owners at risk of driving unsafe vehicles and poor driving conditions.”
