Hello everyone. My voyager is only 63300 miles old and I bought it last summer.

one week ago a check light came up. Cylinder 3 misfire. All 6 spark plugs and coils were replaced. The next day, the car starts roughly and the light came up again, same thing, cylinder 3 misfire. This time I noticed that the coolant level was lower than the day before. Long story short, it’s leaking coolant inside the cylinder 3. Chrysler dealership didn’t give a damn about it and said I overheated my car and needed a new engine.

Does anybody know if is it possible to get the factory warrant ? It’s only 3k miles over it and the five years have not yet passed.
