NHTSA Complaint #11702621 — 2016 FORD EDGE

Complaint Description: My 2016 Ford Edge 2.0L EcoBoost is experiencing a catastrophic engine failure due to "coolant intrusion" into the engine cylinders, a known manufacturing defect associated with the open-deck engine block design in this model year (referenced in Ford TSB 19-2346). The Failure: While driving at highway speeds (65+ MPH) on California freeways, the vehicle intermittently and suddenly enters "limp mode," drastically reducing power and acceleration without warning. This makes it impossible to merge safely or keep up with traffic, creating a life-threatening safety hazard for myself and other motorists. History & Diagnosis: The issue began in early 2025 with a Check Engine Light, which was initially misdiagnosed by a mechanic as a non-critical boost leak. The condition worsened significantly in Q4 2025, leading to dangerous stalls in power. A new independent inspection confirmed the root cause is not a boost leak, but internal coolant leakage into the engine block cylinders. This defect has caused permanent engine damage requiring a full engine replacement. The failure mode is identical to thousands of other complaints regarding the 2.0L EcoBoost engine, yet no safety recall exists to address the sudden loss of motive power.
