Another 2010 owner here. I'm at 280,000km, and other than burning some oil everything still works fine. Usually by this age cars here are pretty rusty, but so far my Prius has held up well. There's a few spots of surface rust in places, but nothing serious.

We had to replace the inverter a few years ago (apparently there was a software update to prevent this failure, but we didn't have it), but even when that broke the car was still driveable, just the ICE engine was running all the time.

The biggest issue I've had is with brakes. Three times now the rear pads have got rusty and I've had to replace both the pads and rotors. My theory is that as they are hardly used, they don't get hot enough to dry out any moisture. Last year I rebuild the rear calipers, so let's see if that fairs any better.

Have you (or any other 2010 Prius owner) heard about or experienced problems with the brake booster / actuator assembly?

I think the issues might be described in this article: https://www.carcomplaints.com/news/2019/toyota-brake-booster...
