anything to check as I approach 100,000 miles?

Just monitor your oil consumption and if you have the means check and clean the EGR components there are good instructions on this forum. As long as other items are done on schedule you should be fine.

 

egr system cleaning

 

100k maintenance calls for coolant, both engine and inverter to be changed. I'd do the transaxle fluid while you are under there too since you probably do not have any records of it being done before

 

Per the 2010 Maintenance Guide, Engine Coolant replacement is at 100K/120 months, Inverter Coolant at 150K/180 months. See Note 3 below. Toyota does not mention replacing transaxle fluid in the Maintenance Guide, but is still a good practice...

 

Danger Danger Will Robinson. It is not a flush. its a drain and refill, very similar to changing radiator coolant. Not to dog your mechanic, he may have a good understanding of a conventional engine but it appears on the surface he doesn't have in-depth knowledge of a prius, you may want to take it to Toyota. In fact he probably won't even use the Toyota WS fluid required. I've read accounts of people on here having Toyota do it for about the same price. And to be honest I trust Toyota over almost any independent mechanic when it comes to actually preforming a task. FYI if you take it to Toyota they'll look at you like you have 3 heads and say its "lifetime fluid", well all fluid has a life. Lifetime for Toyota may only be 125k or 150k miles, you are left to decide what lifetime means to them for your investment. They'll do it with some minor prodding and likely charge you about $150, keep in mind that the fluid itself is about $9 a quart and you'll need just over 4.

I'd also make sure your mechanic uses Toyota Coolant if he changes that.

 

watch for oil burning at this high mileage.

transaxle fluid is just drain and refill.

engine and inverter coolant is just drain and refill as well.

watch our YouTube video, its pretty simple and shouldn't cost you more than 100$ to do all of this service.

 

The service advisor at my Toyota dealership recommended the transaxle fluid change on my 2013 prius. Kind of surprised me because it isn't called for in the maintenance schedule. Not sure if I want to have it done or not.

 

how long are you going to keep it? if more than 150k, i would do it.

 

If you plan on having this car long term I'd do it. Its well worth it. If you are quasi handy you can do it yourself

 

I did my transmission fluid change (130K) on my own. the refill plug was a pain in the nice person to get off, tight space. But the oil came out black. Definitely recommend to do this.

 

No one's mentioned brake fluid change. I believe it's still not in the US schedule? It is in the Canadian schedule, commencing 2014 model year IIRC, and this is really just a policy shift: Honda's been saying tri-yearly, regardless of mileage, for decades. Anyway, Canadian schedule, from 2014 onward, has been saying tri-yearly or 48K km's (30K miles).

@NutzAboutBolts has a video on this too. He uses mechanized suction, but it's readily doable with just some sort of syringe (for basting fluid out of the reservoir at the outset) and brake pedal plus the car's own pump, for the rest. You need some clear tubing, a catch container (Costco mayo jar is my SST, lol), and the kosher bleed bolt attachment is handy, the kind that'll stay on when you push them over the bleed bolt.

One thing, for basting fluid out of the reservoir, you need a VERY skinny tube, think humming bird beak. There's a plastic sort-of basket inside the reservoir, with a narrow slit for access to the rest. The slit is maybe 1/8" wide?

Also, have you been doing the more involved brake inspection, the one that comes up tri-yearly or 30K miles in the US schedule...

Here's the regular interval:



And here's the more involved one, first instance:
