On [XXX], I entered onto [XXX] from Sparks, Nevada eastbound when a check engine light and oil overheat warning came on. I limped the car to the nearest exit [(XXX)]. I had my grandson with me and he was scared. I checked my coolant level and realized that it was dry. I put coolant to the max line of the reserve tank and drove 25 miles to Carson City. When I took it into the dealership at Capital Ford on December 26, 2023, their service manager said this year had a poor design of the engine (2.0L) which led to coolant intrusion into the cylinders. Two days later, they confirmed. My complaint is the FORD manufacturer knew of this issue and had posted several TSBs, but has only issued a recall the 1.5 L engine. I'm now told that since my car is 1600 miles out of warranty, too bad. I believe the FORD manufacturer should replace my engine for free, knowing it failed as a direct result of their poor engineering design. I purchased the car in July 2020 with 26,350 miles and bought the extended warranty. I was never made aware of the existing issues with the coolant leaking into the valves.
