Internal water pump failure: Design flaw where the pump is located inside the engine timing cover; failure can leak coolant into the oil pan, leading to catastrophic engine seizure without obvious external leaks. Described as an inevitable issue. Frequency: very frequent.
Poor fuel economy: Real-world combined mileage reported between 16-20 MPG, with a small fuel tank leading to frequent fill-ups. A primary reason owners seek to replace the vehicle. Frequency: very frequent.
Rust and corrosion: Significant rust issues reported, particularly on door tops under weather stripping, rear hatch seams, and exhaust components (e.g., "flex pipe"). Frequency: recurrent.
Turbocharger reliability concerns (EcoBoost only): Concerns about turbocharger lifespan, with replacements cited in the $2,500 range; described as a "when, not if" failure point, often with one turbo failing soon after the other. Frequency: recurrent.
Suspension and hub wear: Premature wear of wheel hubs and front struts, potentially accelerated by the vehicle's weight or aftermarket modifications. Frequency: recurrent.
