NHTSA Complaint #11675143 — 2017 FORD ESCAPE

The engine block of this vehicle is suspected of having a coolant loss/coolant intrusion fault per my independent, certified mechanic. Issues began about a year ago, before 70,000 miles. Several trips to the Ford dealer did not yield any helpful information. This issue started with an occasional misfire or rough idle on startup. A MIL engine scanner revealed code P0302, cylinder 2 misfire. The code was reset and the issue went away for a short period of time. However, it has been returning more frequently, and I've been stranded more than once out of fear of the engine overheating. Coolant consumption is higher than usual, and it is being replaced with approved Ford coolant only. An independent mechanic performed a few tests, the most basic being inspection of the plugs and cylinder, and noted possibility of coolant in cylinder 2 and 3. A midstream sample of the oil during an oil change was bottled and sent to a specialty laboratory for testing. The oil test confirms presence of small amounts of coolant in the used engine oil. My own research into the issue reveals there was a Ford TSB 19-2346, "Coolant in cylinders, white exhaust smoke and/or illuminated MIL," of which I was never informed by Ford as the original owner since new purchase of the vehicle in 2017.
