NHTSA Complaint #11525142 — 2018 FORD EDGE

My 2.0L EcoBoost engine is having the coolant intrusion into the cylinder issue that Ford has acknowledge in a technical service bulletin, but is not doing anything about it. There is a design flaw with this engine and Ford has redesigned in in later years, but has not issued a recall. The coolant reservoir is getting low and there are no signs of leak under the vehicle as it is leaking into the cylinder. I was getting DTCs for cylinder 2 misfire and my car would shake on startup some times. I changed the spark plugs and ignition packs at 100k and noticed that the cylinder 2 spark plugged looked more brown/burnt (it was burning coolant in the cylinder) than he other 3. The coolant has been low (below the min mark) and I have topped it off 3 times already as the issue keeps reoccurring. Coolant in the cylinder is an issue and low coolant could cause the engine to overheat and blow at any point and could be a catastrophic accident waiting to happen. I spoke about the symptoms over the phone to the service guy at my local Ford dealer and he was already familiar with this issue and confident that I have it based on our conversation. I have plans to take it to my mechanic to have them inspect it as well as the dealer.
