NHTSA Complaint #11655561 — 2018 FORD ESCAPE

2018 ford escape , purchased brand new. . check engine light went on .was on. brought to mechanic; coolant level was low . Engine was misfiring. Reason for check engine light. Discovered one spark plug stuck and corroded. Discovered the reason that coolant was empty. It leaked into the engine. Mechanic says it is a closed system so it cannot be readily discovered. said coolant leaked into the engine . now need new engine. mechanic said this is a design flaw of ford and that many other ford escape owners have the same issue. I paid off my car. I was quoted over 7k to replace the engine. Miles are low on this vehicle. This is unconscionable that Ford has not issued a recall regarding this issue when it appears so many ford owners are having the exact same issue and all are told to pay for a new engine
