Check engine light came on. Fault indicated cylinder #2 misfire. Took vehicle into Ford dealer to diagnose failure. Informed that cylinder #2 has coolant leaking into the cylinder and repair would require that the engine block be replaced. Estimate for repair approximately $10,000. I understand that Ford had a design problem with the 1.5 L Eco Boost engine that was installed in some 2018 Escape models but any opportunity to get this vehicle repaired by Ford has elapsed. Vehicle currently has approximately 109000 miles on the odometer.
