NHTSA Complaint #11698053 — 2017 FORD ESCAPE

Had a coolant leak at 67,000 miles, and the only indication I had was the heat in my car stopped working. I assumed it was a thermostat issue, dismissed it, and continued driving for months like that since it was the summer. Where I live, it's pretty mild in the summer so I wasn't driving with AC or heat on, just with the windows down. I happened to notice the coolant reservoir was completely empty while routinely refilling the windshield washer fluid. This was my first indication anything was seriously wrong with my car, and I only noticed accidentally. I took it into the repair shop, and they pressure tested the system. They discovered coolant was leaking into the cylinders and called to tell me Ford has had a technical service bulletin they issued years ago (22-2229) about the engine in my car. This is known defect with the engine, and that the only way to remedy it is to replace the engine long block. They quoted me over $17,000 for the repair (parts and labor), and told me that there was internal engine damage that could lead to the engine seizing while operating, which is an obvious safety issue. Had I not happened to refill the windshield wiper fluid, I would have had no idea. In hindsight, this wasn't just a thermostat issue...it was a massive coolant leak into the cylinders. I didn't even get a check engine light until I had already discovered the issue and was waiting for a repair appointment. The problem is known by Ford, and is widespread enough in the ecoboost engines that they issued a TSB (but not a recall). They're letting people drive around with these engines, which have subtle failure signs in milder climates, and then leaving them to foot the massive repair bill for a known issue caused by their bad engineering.
