NHTSA Complaint #11664677 — 2017 FORD F-150

My apologies, I sent prematurely, case number 11664674 is already open, but I wanted to add to it. My 2017 Ford F-150 with the 2.7L EcoBoost engine has experienced recurring coolant loss and is now showing signs of internal engine damage. I initially reported the issue to the Ford dealership in November 2024, but no issue was found. On May 23, 2025, the dealership told me I need a new engine. My independent mechanic suspects cracked intake valves or internal coolant intrusion — a known defect in the 2.7L EcoBoost engine. This appears to be the same issue identified in class action lawsuits and previous NHTSA complaints. I feel the vehicle is now undrivable due to my fear of imminent engine failure. My extended warranty expired in December 2023, but the problem started well before that with white smoke coming out of the tail pipe upon cold starting. I am requesting NHTSA investigate these recurring issues, as this appears to be a widespread and unsafe defect affecting multiple years of the Ford 2.7L EcoBoost engine.
