NHTSA Complaint #11658164 — 2018 FORD FUSION

What component or system failed or malfunctioned, and is it available for inspection upon request? The engine experienced coolant intrusion, which is a known defect in certain Ford EcoBoost engines. My independent mechanic diagnosed the issue after I noticed significant engine performance problems. The affected components, including the engine block and cooling system, are available for inspection upon request. How was your safety or the safety of others put at risk? Coolant intrusion can lead to engine overheating, misfires, and in severe cases, engine fires. This significantly increased the risk to my safety and that of others on the road. Had I not addressed the issue promptly, a fire could have occurred while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem was confirmed by an independent, certified mechanic—not by a Ford dealership. The dealer failed to properly diagnose or even acknowledge the problem, which appears to be common based on other consumer complaints. Ford did not identify what was truly going on with the vehicle, despite clear symptoms. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Ford has not inspected the vehicle. The manufacturer was notified, but they declined to take responsibility or offer a solution. There was no inspection by police or insurance representatives, as the issue was caught before a fire or accident occurred. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The engine began running rough and hesitating under acceleration. I also noticed excessive white smoke from the exhaust, and the check engine light came on intermittently. These symptoms began appearing several weeks before the full diagnosis, and Ford service failed to address them accurately during prior visits
