On the 2010-2020 Ford Fusion, ford Fusion Hybrid spans two generations with different high-voltage batteries — degradation patterns differ. 1st-gen 2010-2012 (NiMH, ~1.4 kWh): typical degradation appears at 100,000-150,000 miles with reduced EV-mode range and increased ICE intervention. Replacement runs $2,500-$4,000 at independent hybrid specialists. 2nd-gen 2013-2020 (Lithium-ion, ~1.4 kWh): better thermal management has led to longer life on average but cell imbalance issues appear at 150,000+ miles. 'Stop Safely Now' warnings often precede full failure. 2013-2020 Energi PHEV variants share the architecture but with larger 7.6 kWh batteries — separate degradation curve. Owners should check cell balance via OBD-II scanner with hybrid module support (Forscan recommended).

This issue also affects: Chevrolet Bolt EV, Ford C-Max, Ford Mustang Mach-E

Common Symptoms

Reduced electric-only driving range
Decreased fuel economy (gradual decline)
"Check Hybrid System" warning on dashboard
Slower-than-normal acceleration or power loss
Battery charge indicator drops faster than normal
Unusual noise from battery compartment area

How to Fix

Check warranty first - Ford covers 8yr/100k miles (10yr/150k in CA, CT, MA, ME, MD, NJ, NY, OR, PA, RI, VT, WA states). If out of warranty, aftermarket/remanufactured battery packs from GreenTecAuto ($1,550-2,950 installed) are significantly cheaper than dealer replacement ($4,000-7,000). Individual cell replacement at specialized hybrid shops ($800-2,000) is an option if only specific cells have failed. Battery reconditioning is a temporary fix that may restore 60-80% of capacity for $300-800.
