NHTSA Complaint #11589812 — 2017 FORD FUSION

Coolant intrusion into cylinder 2 cause misfires and lead to failure 2.0L fusion platinum with 90,0000 miles Noticed low coolant level, sloshing novices behind the dash). Machine said the did hear any, I was quite loud for 6 months. Always on excel and sometimes waterfall sounds at stops. Flushed and replaced coolant. Pressure tested 40 min. Sloshing noises started 3 days later. Level Dropped again and caused a missfire. All plugs replaced. Pressure test overnight, no leaks or coolant drop per dealer. Sent home with a nice bill and statement saying nothing is wrong. Rep gets frustrated why I keep asking why and were is the coolant going. Recommended I buy an extended warranty plan. 3rd time same misfire. Called and told me there is coolant in the cylinder and is $9,500 to replace. I wish the customer could she the photos from the scopes. It’s just hard to trust people The cars not worth that going to another dealer to trade in 🙏🏻
