. It has 179k on the clock, so the known CVT issues would have surfaced by now.

Don't they use the Toyota planetary CVT? Or an equivalent transmission made under license from Toyota? What are the known issues?

The Fusion hybrid/energi uses an electric CVT. None of the horror of belt CVTs. Service interval is 150k; it's literally just two electric motors that vary in speed to control the input-output ratio.

Yup, that's the Toyota design. It's ingenious actually. Toyota licensed it to Ford with the first Escape hybrid.

The HF35 is a Ford-built unit that debuted with the Mk5 Mondeo/Fusion/C-Max hybrids in both HEV and Energi models. It is still used in Ford hybrids today and is built under license from Aisin. Pre-2013 Ford hybrids used an Aisin unit.

About 10% of the 2013-15 models were known for transfer gear assembly bearing failure due to a bad batch of bearings. Failure usually occurs between 50k and 80k miles. Failures are random and not tied to a specific batch of VINs. There's a few TSBs on it. Ford covered the units under the HEV powertrain warranty up to 100k miles.

If yours has made it to 100k without a catastrophic failure, it does not have the defective bearings.

Anyways. Misfire city here. A set of four new OE Denso coils are $125 from CrockAuto and will ship from the same warehouse as four new Motorcraft SP530X plugs.

I have owned this car since new. It took 12 years and 179k miles for it to experience its first failure of any kind. It's still running on the original 12V battery even. So I ain't mad.
