“Coolant leaking into cylinder 2, misfire (P0302), overheating, and white smoke from exhaust. Mechanic diagnosed potential head gasket or coolant intrusion issue. Vehicle is out of warranty. This seems related to known issues on EcoBoost engines, including TSB 19-2208 for later models, but no recall exists for the 2015 model. Major safety concern and potential engine failure”

“We purchased a used car for my son to use in college. While driving on the hwy, the car started loosing power and just died on the side of the road. He was towed towed to a Ford dealer and was told he was leaking coolant into cylinder #4, which is a KNOWN PROBLEM AT FORD and an active recall for model years 2016-2018. Our 2015 has the identical failure mode and is not covered in the recall!! We were told $9000 to replace the engine block ... It only has 84,000 miles on it!!!!”

“The contact owns a 2015 Ford Fusion. The contact stated while driving 40 MPH, the temperature gauge indicated that the engine was overheating, and the vehicle started losing motive power. The contact turned off the vehicle for three minutes and then immediately drove the vehicle to the local mechanic. The vehicle was taken to two independent mechanics. The first independent mechanic diagnosed the vehicle and determined that the head gasket had failed and needed to be replaced; however, the mechanic was unable to perform the repair. The vehicle was then towed to the second independent mechanic where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that there were no recalls on the VIN associated with the failure. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was 144,000.”

“The vehicle started to over heat because the vehicle is loosing antifreeze through the head/engine block wall. This is a 1.5L Ecoboost motor. I had the water pump and radiator lines replaced 2022 by Gorilla Techs, but that did not fix the issue. It has progressively gotten worse over the course of two years. Other Ford owners, they have had engine repairs covered. However, the recommend solution is to replace the engine with a long block engine. This repair is a result of poor engineering. A new engine from Ford is priced at $6,000 and does not include labor or other one time use parts and fluids.”
