The contact owns a 2018 Ford Fusion. The contact stated while driving 45 mph, the engine started to overheat, and there was smoke coming from underneath the hood. The message "vehicle temperature overheating" was displayed. The contact pulled over to the side of the road and allowed the vehicle to cool down. The contact was able to continue driving; however, the failure recurred several times while driving. The contact pulled to the side of the road several times until arriving to the residence. The vehicle was taken to the dealer, where it was diagnosed that the pcm had failed. Additionally, the dealer diagnosed there was coolant intrusion in the engine cylinders. The dealer determined that the engine needed to be replaced. The vehicle was not repaired. The contact related the failure to Ford campaign number: 21n12. The manufacturer was notified of the failure and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 181,000.

I was driving and all of the sudden engine overheated and car could not drive over 10mph during an extremely bad storm at night on the highway putting me in extreme danger if someone were to have been behind me. There were no engine lights on or warning signs of this happening and just happened out of nowhere car was driving fine before it happened. Issue happened on September 26th, 2023. This is the second engine problem I have had since getting the car in 2021. Last issue was with the top half of the engine cac/intake manifold and luckily was under warranty or would have been over $6,000. Had vehicle towed to Ford dealership and there verified a check engine light fault. P0303 active in pcm. Upon diagnosing the concern found that the head gasket is leaking into cylinder 2 and 3 due to a failed cylinder block assembly. Need to replace the short block assembly with an updated design. Was quoted $8,700 to fix the issue. I can't afford to pull that kind of money out to fix a car that isn't even 5 years old. Car is no longer under warranty.

On 3/6/2020 we took vehicle in to dealership. They performed oil change and reprogrammed pcm due to recall that was issued on my vehicle. 2 days later we started having issues with gas mileage sensor. Dealership to us to reset. Vehicle continue to have ussues warning lights are on, now we have parasitic drain. Car wont start. We have gotten jump start next day vehucle wont start. We were told battery is good. Issue is with module. I went through on last Ford vehicle and after 4 repairs, spending out of pocket thousands of dollars they never fixed Ford focus so I purchased Ford Fusion and now the exact same issue. It also may loud sound during jump start. Vehicle has been disabled since 3/27/2020.
