Check engine light displayed despite the fact that the car seemed to be running fine. I took the car to a repair shop and then to Ford Service who documented the diagnostic code P0302 Misfire4 on Cylinder #2. They did a pressure test. and found coolantintrusion on cylinder #2. The recommended repair was to replace the engine at a cost of $8700. My Ford EDGE has only 61,000 miles on it. I have found the following information on this car’s engine indicating this was a known problem. I purchased this car < 2 yrs ago. Prior owner was not aware of any notification from Ford.
