    Hello all. I'm starting to shop for a gen2 for my work commute.

    I'm trying to keep it in the $6-7000 range. Because of this, most vehicles have 100k+ miles. I've seen a few ads for vehicles with the HV battery just replaced.

    Assuming a new dealer replaced battery versus original HV battery with 100k+ miles, which would you choose?

    Thanks!

    Assuming a new dealer replaced battery then I'd consider that a plus. I'd caution however that this would be a fairly big assumption to make, unless you have actual proof, by way of receipts from Toyota, that it really was a NEW battery.

    If not a new battery then I don't think I'd consider it a positive. To be honest I think I'd prefer to have one that had never been touched.

    First of all, I would look to see why the battery was replaced so soon. I have 205k on original, have seen up to 250k before needing replacement.

    You're unlikely to get to the bottom of any systematic reason for this. While it's only a minority of cases, it's clear from looking at the reported failures from users here that some batteries do fail young (100 to 150 kmiles and < 10 years) for no discernible reason.

    But yeah, it would be a good idea to check out the health of the battery cooling system for any secondhand Prius with the sort of mileage that the OP is considering.

    Thanks for the input! Yes I'll definitely ask for paperwork.
