Leading up to the failure the smell of coolant was noticeable after driving the van. Coolant reservoir never showed a drastic decrease in coolant but I would top minimally every 6-8 months. I took the van to 3 different shops stating that I smelled coolant with zero evidence of a leak. System was tested and found not be leaking coolant at each shop and recommend continue to drive the vehicle. At 61,000 miles CEL came on with code P0305. Code was for a misfire in cylinder 5. CEL ended up going away only to come back a few days later. Engine never displayed any signs of overheating and consistently runs at a normal operating temp according to the onboard display. Inspection showed coolant pooling in cylinder 5 and wear on the camshaft. Oil changes completed every 3k miles and the recommendation from shop was to put in a new engine in a car 1K beyond the warranty. Reading numerous posts suggests that this is a continued issue that Chrysler dsn’t want to take ownership for on their products.
