prius 2015 @ 150k miles

At this point, you should just complete your travel as is. There are no belts on the car to change. You don't want to do any maintenance on a car without problems, you can potentially create a problem by changing things you don't really need. Especially with unknown shops and mechanics that may or may not be competent in servicing a Prius.

I think you have all the basics covered, maybe recheck your oil and coolant levels. But other than that, you should leave everything as is.

 

have you owned it since new? do you know the service history?

what did the brake service consist of?

 

if you've done all the regular service since 50k, just keep doing what you're doing.

when you get home, look into cleaning the egr circuit, and a few other things not contained in the maintenance schedule.

 

yes, as you know, there's not a lot to do until 100 or 120k

 

What's manual say

 

U got screwed

 

With 150k you definitely want to look into EGR cleaning, ASAP. At least 50k earlier would be better. 150k is when the head gaskets start letting go, quite regularly. It’s a third gen “feature”.

there’s precious few professional shops* doing EGR cleaning BTW; don’t even entertain asking a Toyota dealership to do it; they’re a cruel joke. DIY if at all possible is the way to go.

Have a look at my signature for more info on EGR cleaning. Transaxle fluid change, various other are of interest too. If on a phone turn it landscape to see signature.

* Tampa Hybrids and Hybrid Pit Stop (LA) are worthwhile

 

He's in connecticut, rust is very common

 

South Main Auto guy (in upstate New York) was dealing with a rusted out solid rear axle suspension. The fix was simple: got a salvage replacement shipped from a Florida wrecking yard.

 

Before 2500miles trip i would check that cruise control works

Before taking trip that long i would also pay special attention to tires, be it old or new tires. I had tiny leak in my other car and eventually the reason turned out to be screw in the tire.
