My 2019 Ford Edge with the 2.0L EcoBoost engine began experiencing a misfire, loss of power, and white smoke from the exhaust. No engine light was on when it started and the car has less tan 46K miles. I had the car towed to a certified mechanic and he confirmed that coolant is leaking into my cylinders, which matches the issue described in Ford TSB 19-2346. This appears to be a widespread manufacturing defect affecting many vehicles with this engine. The presence of coolant in the combustion chamber caused catastrophic engine failure and poses a safety risk due to sudden loss of power while driving. I have been told that to fix the issue I need to replace the whole engine. Repair costs are estimated at $10,600 for an engine replacement at a local repair shop. I would expect it to be even higher from a Ford dealer. Ford has acknowledged this defect in a TSB 19-2346, but no recall has been issued. I am submitting this complaint so NHTSA is aware of the defect and its safety implications. I urge NHTSA to investigate this issue and require Ford to take responsibility.
