NHTSA Complaint #11673651 — 2018 FORD ESCAPE

Date of Incident or Diagnosis: 7/15/2025 I am writing to formally report a serious issue with my 2018 Ford Focus, which has required a full engine replacement due to a known and widespread defect — coolant intrusion into the engine cylinders, specifically cylinders 1 and 3. This is a manufacturing defect and not the result of normal wear and tear or improper vehicle maintenance. Coolant intrusion leads to engine misfiring, overheating, stalling, and ultimately complete engine failure — posing both safety risks and a significant financial burden to owners. This issue is especially concerning as there is no check engine light or prior warning before the damage becomes irreparable. In my case, the damage was discovered only after experiencing performance issues and having the vehicle professionally diagnosed. This problem has been widely reported by other owners of 2018 Ford Focus and Escape vehicles with similar 1.5L EcoBoost engines. Ford has previously issued technical service bulletins (TSBs) and recalls for similar issues in other model years and engine variants, but this specific year and model have not yet been included — despite exhibiting the exact same symptoms and root cause. I strongly believe that this failure is a design and manufacturing defect, not an isolated incident. It is unfair to hold consumers responsible for the cost of an engine replacement due to a flaw that Ford is already aware of in similar vehicles. Requested Action: I urge the NHTSA to investigate this issue further and push for an official safety recall of 2018 Ford Focus vehicles affected by coolant intrusion. Engine failure while driving could pose a serious hazard to the driver and other motorists. Ford should be held accountable and required to cover the cost of repairs for all affected vehicles, not just those included in previous recall campaigns.
