What are the risks of buying a 2017 Prius with only 15,000 miles?

100% I'd buy this car. I'd be prepared to swap out the 12V battery and tires possibly, if you can't determine if/when they were ever changed. That's all I've ever done, except for routine 10K oil changes, engine and cabin air filters, in our 2016 with 78K miles.

 

Me, too. Great find!

My 2012 Prius v has not reached 32k miles and everything is working just fine. I've only done regular oil changes, replaced the coolant, and 12 volt battery in 12 years.

The HV battery still charges to its full capacity. I monitor the 12volt, the ICE coolant temperature, the inverter coolant temp, and the HV battery temp with a Scangauge 2. The temps have never been above normal.

 

Probably not much of a risk - just remember what Miles don't do to a car Time does - so go down the maintenance list and ensure its done - Luck and enjoy

 

I'd buy.

Risks? Where it "sat" or was stored and area weather conditions.

FWIW
Typically older low mile vehicles have motor and suspension rubber seal deterioration from no use.
In this case, the car was driven about 200 miles a month... so okay to me.
If in a snow zone with road salt usage, sitting with that salt could bring rust damage... so inspect the undercarriage.

As mentioned above, aged out 12v battery and tires should be replaced.
I would also change all (all) fluids (protentional moisture accumulation and age) and lube all the hinges, caliper pins, seat tracks, weatherstrips, etc. too.

Hybrid battery, brakes, transmission, stereo, suspension.... all unknowns but I'd think all are ok with the 200 mile a month use.
So in addition to purchase price, perhaps another $2000 (including new tires/ alignment/ balance, 12v battery/ key fob batteries, brake/coolant/trans/motor fluid changes at a shop) to recondition.

Good luck with your decision.

 

I don’t see any risks, as long as you follow the advice already given. I’m sure there will be some who will claim the hybrid battery is not up to snuff, but that goes contrary to the Priuses around where I live. I think you have a shot at a gem. Go for it!

 

Keep an eye on the exhaust gas heat exchanger. I believe the 2016 and early 2017 didn't get the redesigned one.
