NHTSA complaint #11762811

Owner complaint summary

My 2020 Ford F-150 (5.0L V8) experienced a sudden loss of engine power and stalled completely while I was driving. In the days leading up to this, the check engine light had illuminated, and I later discovered the vehicle had consumed a severe amount of engine oil — the dipstick read below the "add" line. Critically, no low oil pressure warning light or audible chime alerted me to the oil loss before the stall occurred. After the initial stall, the engine continued to struggle to maintain idle and stalled repeatedly whenever RPM dropped to approximately 1,000, making the vehicle unsafe to drive. I had the vehicle towed to a Ford dealership for diagnosis. The dealership's estimate confirmed the need for a full engine (long block) replacement, at a cost of approximately $19,824.56 (total estimate $21,491.04). I am aware that Ford issued Technical Service Bulletin 19-2365, which acknowledges that 2018-2020 F-150 trucks with the 5.0L engine may experience excessive oil consumption exceeding one quart per 3,000 miles with no visible external leaks, attributed to oil being drawn into the engine during deceleration fuel shut-off events. I believe this defect directly caused my vehicle's stalling and oil starvation, and that the lack of any dashboard warning prior to the failure is a separate and significant safety concern, since a driver has no way to know the engine is being damaged or that a stall is imminent.
