It had a #2 cylinder misfire error in the history when I had a mechanic look it over. It had been cleared and never came back prior to the engine hatching.Do they said what would cause it? Did they found any bad rocker bearing? thanks for posting.
Dealing with the Chrysler dealer was an awful experience so bad I had to order my own engine.
I drove 90 miles to pickup other parts that I had to locate because they were a week out according to the service department.
My wife and I were stranded out of town for a month!
Anyway they said "my coolant level was low and an air pocket could have been trapped near the #2 cylinder and blocking coolant causing this area to overheat".
I checked the coolant levels and oil before the big trip across country.
We were running up the road the check engine light came on flashing buy the time I pulled over she was dead.
If you look a the pile of parts the piston head is mangled I think it dropped a valve or seat but no convincing them of that.
No help from FCA because I was 1500 miles past the warranty and I was a second owner.
