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 $12,000. My primary concern is that there was absolutely no warning before this major failure. No warning lights, no diagnostic alerts, and no indication that a significant transmission fluid leak or internal transmission damage was occurring. A safety-critical failure of this magnitude should provide drivers with some form of warning before resulting in complete transmission failure.

I have a check engine light on due to an issue in the emissions system. The issue is that the purge valve is stuck open. I know that this is an issue that you had a recall on for older models of the ford focus for this same reason. All the systems of a stuck purge valve are the issues I am having with the vehicle.

Last month, while transporting my brother to his arm surgery in Chapel Hill, NC, I observed unusual and audible shifting behavior when engaging the vehicle's sport mode. This mode is typically utilized for extended journeys on highways and interstates. Although the anomaly was brief, I did not initially consider it significant. Several weeks later, upon departing from my community college campus, I encountered a red light near Santa Fe Drive. The vehicle exhibited a hesitant and labored acceleration, eventually moving forward. This incident was particularly concerning given the high volume of traffic during that time of day. I subsequently stopped at a nearby 7-Eleven for fuel, suspecting a low fuel level might be the cause. No engine warning lights or mechanical indicators were illuminated, and the oil life was at 70% with appropriate oil levels. Fast forward to the last week of January. On Wednesday the 28th, I began to notice recurring shifting issues with the vehicle during a class break. Additionally, engaging reverse consistently resulted in a harsh shift. As I was leaving my neighborhood to return to class, the vehicle completely failed to engage gears or accelerate. At this point, both the wrench and check engine warning lights illuminated. Upon returning home, I utilized the code reader provided by my mother last Christmas, which displayed the code "P0772." This confirmed my prior research regarding potential issues with the EcoBoost engine. I am relieved that this mechanical failure did not occur amidst the heavy traffic typically found on 210 Murchison South , I-295, Bragg Blvd Fayetteville/Spring Lake and other routes heavily trafficked due to the military base. The high speeds on these roads could have led to a dangerous situation, potentially causing a rear-end accident or other involving other drivers who may be speeding or inattentive. I am grateful that I did not experience a stall in the middle of traffic, which could have compromised my safety.

The check engine light came on. The car was regularly losing coolant but none was leaking out. I topped it off but the coolant level lowered again. My mechanic suspects it is a problem with the Ecoboost engine where the coolant leaks into the cylinders. I know there is currently a class action lawsuit against for for Fusions from 2013-2019 addressing this problem.

I purchased a used 2020 Ford Fusion from Carmax n 2023 with about 56,800 miles. A week later was involved in a nor side impact accident on the back end driver side, insurance paid for a dinted door and there was no other issues with the vehicle according to SONS ford. In 2024 I was on the highway (going about 80 mph) when my engine light came on, no more than 3 minutes later all the lights in my car flickered and i lost power to my entire car almost causing me my life, roadside assistance and a mechanic who had thankfully pulled over explained that my alternator completely shredded my belt. I paid for both my alternator and belt to be replaced But most recently (2025) I continued to whirring and knocking noises for 3 days (no warning lights) , I took it to firestone who stated I needed a motor repair so I got it towed to the dealership. A Ford certified mechanic stated my Flex Plate was cracked and it begin breaking off and how I needed a new starter as well leaving the car inoperable. They confirmed this was very uncommon due to the car age and the miles on it (80,000 mi) I’ve also reviewed the complaints on the federal safety agency and it looks like a lot of 2020 ford fusions are having these issues but yet no recall.
