The 2.5L NA is simplest; EcoBoost engines add power but need cooling attention.
Yes — including steering-related recalls; verify completion before buying.
It depends on the engine fitted. The 2.5L naturally aspirated and 2.0L EcoBoost petrol engines use a robust timing chain that rarely requires replacement. However, the 1.5L and 1.6L EcoBoost variants utilise a timing belt. This belt requires strict adherence to service intervals to prevent degradation and catastrophic engine failure.
The lithium-ion battery pack in Fusion Hybrid and Energi models is highly durable, typically lasting between 100,000 and 150,000 miles before showing significant degradation. Dealers should check the dashboard energy monitor during a test drive to ensure the battery holds charge and transitions smoothly between electric and petrol power.
The Power Transfer Unit on AWD models is technically sealed for life, but technicians strongly advise changing the fluid every 30,000 to 40,000 miles. The unit sits close to the exhaust, causing the factory gear oil to overheat, degrade into sludge, and eventually destroy the internal bearings if left unchanged.
