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
Vehicle fails to start (complete battery failure)
Hybrid system shuts down and runs on gasoline only

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.
