NHTSA Complaint #11641017 — 2017 FORD EDGE

**Incident Summary:** I am reporting an issue with my 2017 Ford Edge with an EcoBoost engine. The vehicle has 39,844 miles on it. The component that failed is the head gasket, which has warped due to coolant intrusion. This issue led to the necessity of a full engine replacement. The vehicle is available for inspection upon request. **Safety Concerns:** The malfunction compromised my safety and the safety of others as it led to the car overheating and the check engine light coming on. These symptoms started during the summer. Overheating poses a significant risk, potentially causing engine failure while driving, which could lead to dangerous situations on the road. Moreover, the presence of coolant in the oil and exhaust fumes indicated severe engine damage, which could have resulted in a fire hazard if not addressed promptly. **Problem Reproduction and Confirmation:** The problem has been reproduced and confirmed by an authorized Ford dealership. They performed a detailed inspection and diagnosed that the engine needs to be replaced due to the warped head gasket and coolant intrusion. **Inspections:** The vehicle and the failed component have been inspected by the Ford dealership. No inspections have been conducted by police, insurance representatives, or other authorities. **Warning Signs:** There were warning signs prior to the complete failure. The check engine light started coming on intermittently over the summer, and the car began to overheat. These symptoms indicated an underlying issue, which eventually led to the discovery of the warped head gasket and coolant intrusion. **Assessment:** Based on the inspections and symptoms, it is clear that the coolant intrusion into the engine led to the head gasket's failure. This is a known issue with EcoBoost engines, and it caused significant damage, warranting a complete engine replacement.
