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 $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’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.

In early October 2025, the vehicle was taken to an independent dealership service department for a routine oil change. Several weeks later, the vehicle appeared to be leaking fluid and began experiencing loud knocking/clacking noises, significant vibration, and drivability concerns, especially during acceleration. On October 10, 2025, while parked at a family member’s residence, the vehicle would not start. Due to safety concerns, the servicing dealership arranged for the vehicle to be towed for inspection. Technicians found a split transmission hose causing transmission fluid loss, which was repaired; however, the abnormal noises, vibration, and drivability issues persisted. Further inspection identified loud popping/clacking noises from the bell housing area. The technician physically inspected the flex plate and documented that the flex plate was cracked. The dealership advised that a cracked flex plate can worsen, cause severe vibration, damage related components, and lead to drivability issues or potential loss of propulsion. Because of the nature of the failure and symptoms, the vehicle was removed from regular use due to safety concerns. The vehicle was later taken to a manufacturer-authorized Ford dealership, which confirmed flex plate failure but stated the vehicle did not qualify for a customer satisfaction program due to engine variant. A goodwill/financial assistance request was submitted and denied. Technician diagnostic documentation from the manufacturer-authorized dealership was requested but not provided prior to filing this complaint. No crash or injury occurred; however, the failure created a risk of sudden inability to propel the vehicle while driving, including at highway speeds. The vehicle remains unrepaired and parked due to cost and safety concerns.
