    I am looking to buy this low mileage 2017 Prius(4500 miles) owned by an elderly couple. I had the dealership run a diagnostic test with battery results, just to be sure everything is ok as it has hardly been driven. These are the results.

    If you can provide any info on the results, especially the engine and hybrid battery health, please let me know. Thanks.

    Are the highlights your’s or the dealership’s? Did you ask them to explain the diagnosis that you had them perform? If so, what did they tell you? If not, why not?

    Looks about right for a half-used up Prius with oddly few miles (kms) on it.

    It isn't a bad report. If I found the right deal on a car like that, I'd get it new tires & 12v battery, a fresh set of wiper blades and then fairly expect a good six years or so before anything got expensive.

    Is that what you want out of it?

    The report is only good at telling you what the hybrid battery was showing at the time they hooked the car up to techstream 63% SOC that dropped to 57% SOC while testing.. Kinda like one screenshot from DfPrius or Hybrid Assistant app, it only shows a small part of the hybrid batteries range.

    Thanks for posting the printout, now more of us know what is shown in the basic version of the health check.
    Looks to me like they didn't even put the car in maintenance mode during the test run.

    They are the dealerships. I believe they just wanted to indicate what I had asked for. They didn’t tell me much, in the end I purchased the vehicle. I decided if I need to replace the battery at some point it will still be worth it.

    Ya thats kind of what I’m looking to get out of it. If it is 6 good years and 6 ok years after that I will have done very well. I figure if I have to do a hybrid battery replacement it would still be worth it due to such low kms.

    Hmm, thanks for that info. I sort of suspected it wouldn’t show much. Is there any low cost way of me doing a more detailed look at the state of the battery now that I own it? It would give me an idea where I’m at with it.

    DrPrius app priusapp.com and an odb2 bluetooth adapter is a good way to started monitoring the hybrid battery.
    And another thing that works is getting a kilawatt meter to monitor how many watts it takes to fully charge the battery from empty.

    Both of those suggestions don't always tell you exactly what condition your hybrid battery is in now, unless you post screenshots here to compare with what other previous and current Gen 4 Prime owners have and are seeing respectively with Primes.

    Hybrid Assistant is another app that is used quite often by other members here and includes some data about the engine too.
    Hybrid Assistant

    CarScanner app gives the most data about the engine of the three.
    Car Scanner ELM OBD2 – The best car OBD2 diagnostic solution for iOS and Android in your pocket!

    each web page I've linked includes which ODB2 adapters each app recommends
    and all three apps recommend different adapters.
    Prices at both Amazon and eBay range from around $20 to around $150 for an adapter.

    Panlong $20
    Vgate vLinker series range from $30 to $65 the high end ones FD, FS-bt and MC+ all work on Android, iOS and Windows ( if you want to connect your car to a windows laptop ).
    OBDLink MX+ $140

    Sorry for the overl.oad, it's a lot even for me after 6 years of actually using that stuff.
    My personal recommendation is the panlong adapter that @jacktheripper used while building the DrPrius app for the Gen2 Prius and of course the DrPrius app.
    Reason being, it was the easiest way for me to start learning about what was going on inside the hybrid battery case while the Primes in Ready mode. And probably more importantly, it was built with getting the hybrid battery data first and foremost, which is probably why there are a lot of priuschaters that use it, including me.
