Hybrid 2.5L engine 200,000 miles eith good maintenance & likely more depending how its driven, hybrid variant will have significantly less cold start stress from cold oil lower flow than in its former conventional drivetrain like Ford Fusion.
Hybrid-electric powertrain the HF55 motor-generator could easily reach 500,000 miles given earlier HF35 with smaller less robust versions with lower flow oil pumps & smaller bearings reached this, ditto on the inverter & possibly the traction battery with 1 major caveat: the cooling system! 3 phase electrical drives can run constant speed a good 30 years, but unlike an engine they are very sensitive to sustained heat, the inverter-battery coolant pump reduces flow during a heavy load condition, even for seconds, instant failure or massively reduce the remaining life of electrical components.
Hopefully the inverter-cooling system is robust & over capacity, because the engine "overtemp" light equivalent for inverter cooling while towing uphill is not "pull over & cool down before continuing", its "your inverter might make it to the destination, get a new one pre-ordered".
Thats the only thing that worries me about plastic HV hybrid powertrain coolant line tubing
Of the hybrid electric components, the HV battery will probably be the 1st to start losing capacity & needing replacement. Fortunately alot less time & work than replacing a transmission, anyone can do it with $50 of tools & a strong appreciation for electrical safety working on Class 3 voltage sources.
Not difficult to replace a HV traction battery in your garage with electrically insulated tools, but if you dont have common sense and electrical safety training, a mistake will kill you quickly.
