NHTSA Complaint #11525225 — 2018 FORD EDGE

Please Note: I filed a previous complaint (#11511950) on 03/15/2023. Please refer to Ford Technical Service Bulletin TSB 22-2229 issued in June 2022 regarding coolant intrusion into cylinder head on 2017 - 2020 Ford Ecoboost 2.0L engines. Due to a faulty design all of these engines are all destined for total failure. In their own technical service bulletin Ford describes the appropriate fix as total engine replacement. Because of what should surely be considered Ford's manufacturing defect, coolant inevitably intrudes into the cylinder head(s) mixing coolant with the fuel. Once this has begun it is only a matter of time before the engine fails. If such a total engine failure (hydrolock) occurrs at speed the results could be catastrophic, leading to deaths and injuries. Under these circumstances it is difficult to understand why there has not been a recal on these faulty engines. Further, Ford has already offered owners of Ford vehicles with the Ecoboost 1.5L engines, subject to the same problem for the same reason, total engine replacement regardless of mileage.
