The warranty for my 2013 states this:
So is it only covered for a Focus? That makes no sense.
Your vehicle’s unique hybrid / electric components are covered during
the Hybrid / Electric Unique Component Coverage, which lasts for eight
years or 100,000 miles, whichever occurs first.
The following hybrid parts are covered during this extended coverage
period: high-voltage battery, hybrid continuously variable transmission,
Inverter System Controller (ISC), DC/DC converter, high-voltage
battery connector, battery pack fan assembly, thermistor probe, Hybrid
Battery Pack Sensor Module (HBPSM), Battery Energy Control Module
(BECM), and the PHEV onboard charger.
The following Focus Electric unique parts are covered during this
extended coverage period: high-voltage battery packs, high voltage
charger, DC/DC convertor, Electric Drive Module Assembly (includes
electric motor and gearbox), trans range and charge cord'
