Ford Expedition Reliability
Are Ford Expeditions reliable? Best years, EcoBoost concerns, and 2021 data.
The Ford Expedition is a capable full-size SUV with generally solid reliability - but the switch from the 5.4L V8 to the 3.5L EcoBoost V6 in 2018 introduced a new set of risks. The EcoBoost is a powerful engine, but its twin turbos, timing chain, and carbon buildup create expensive failure points at higher mileage.
