My antifreeze AND oil keep going empty after driving the car after so many days..... there is no leak on the ground, and i do not smell anything inside the cab. No lights are on the dash I took it and has them plug it in just incase and the only thing that came back as a possible issue is the brake pad. Otherwise they said there was no issue However, there is an issue and no one can seem to figure out what it is!

Exhibited signs of a coolant leak followed by throwing a code about cylinder 4 misfiring. Took my car to the dealer who confirmed that there is coolant leaking into cylinder 4, and it is similar to other defects found in many 1.5 liter ecoboost engines from this model line. Was told that my VIN did not qualify for the recall that is only for the ecoboost 2.0 liter engines even though they have the same defect.

The engine experienced a sudden failure that caused the vehicle to become completely inoperable. Prior to the failure, the vehicle exhibited intermittent hesitation, rough idling, and loss of power during acceleration. These symptoms began several weeks before the complete failure. No warning lamps were illuminated at first, but shortly before the breakdown, the vehicle displayed a check engine light and a “Service Engine Soon” message. While driving, the vehicle abruptly lost power and became unsafe to operate. I was forced to pull over immediately, which created a safety risk to myself and other drivers due to the sudden deceleration and inability to maintain speed in traffic. The vehicle would not restart afterward. A repair facility has confirmed that the engine has suffered a major internal failure and requires replacement. The estimated cost of repair starts upwards of $5,000. The vehicle is currently non‑drivable and remains available for inspection. The issue has been reproduced and confirmed by an independent service center. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. However, I have found multiple similar complaints from other owners reporting the same type of powertrain failure, suggesting a potential pattern or defect affecting safety.
