NHTSA Complaint #11694247 — 2018 FORD EDGE

The problem began in early August 2025 when the check engine light came on and the vehicle misfired. A Ford mobile technician inspected it before 8/23/25, confirmed Diagnostic Code P0303 (Cylinder 3 Misfire), but said it was likely just a bad ignition coil. Based on that, I went to Midas on 8/23/25 for a tune-up and coil check. On 9/29/25, the check engine light returned and for the first time the coolant over-temperature warning illuminated. Midas confirmed coolant intrusion into Cylinder 3: borescope and pressure test showed leakage, leak-down test failed with air entering the coolant reservoir, and visible coolant loss was present. At 80,445 miles, the engine was deemed unsafe and required full replacement. Hawk Ford confirmed no warranty extensions or programs applied. The repair cost was $10,500 out of pocket. This defect matches Ford TSB [XXX] , is widely reported in EcoBoost engines, and creates a serious safety risk since the vehicle misfires, overheats, and may stall while driving.
