I just took my 2014 PiP in for my 150K service. To date, all I've done is oil changes and tires, then inverter coolant, engine coolant and plugs at 120K. The factory brakes are both at 5 mm, which blows me away, after 150K miles! They did a transaxle fluid change and oil change, checked the brake fluid and didn't recommend replacing it.
And that ladies and gentlemen this is exactly why we own a Toyota Prius plug-in. I felt the same way with my 2013‘s. Just recently sold both of them and bought a matching set of Prime’s.
Get the EGR circuit cleansed yet? That's a job that isn't listed but necessary. Glad to hear ownership so far has been uneventful.
It's a very do-able home project. But one that should be on your list soon. Just be thankful you don't have the Prime and attempt the egr circuit cleanse. Lots more things need to be moved for access. Good luck with the DIY.
