    I am sure you paid or owe a lot of money after buying a 2014 Prius this month. At least be sure the car is solid before Carvana goes belly up. Which could be soon.

    Vin verification for good pistons and rings on a 2014. Last six digits would be higher than 358779 from Plant 0 or higher than 791355 from Plant 1.

    Sorry, I forget to check stuff like this a lot. It's a think I'm working on. I did look at the vin number though, and it's from plant 0 and the number is definitely higher.

    In other news, I finally found good time to try that thing suggested about jumping straight to the 12v battery and it did nothing. Still haven't been able to try a slow charge yet, but I'm off work tomorrow and will be heading down to see if maintenance can help me figure something out with some of the stuff they have access to that I don't. Fingers crossed we get it running, so I don't have to have it towed 2 hours to the facility carvana wants me to take it to for their warranty stuff. But after tomorrow, I will try to give you guys another update on if we figure something out to get it started up.

    perhaps a bad fuse. did you jump directly to the car battery leads with the 12v completely out of the circuit?
    another thing to look at is the 12v negative lead to body connection, sometimes loose or corroded

    No, I didn't have any tools to disconnect with, so I just jumped straight to the 12v battery. It probably wasn't the best way to do it, in hindsight, but I'm going to talk to maintenance tomorrow, and they should have the right tools to try all the things I can't do on my own.

    sometimes a defective battery will prevent 12 volts from getting past it

    Hopefully, it's not so bad that it won't hold a charge long enough for me to get it to the shop in a couple of weeks. I got someone in maintenance to take the battery out and put it on a slow charge for a couple of hours and we're gonna test it after to make sure it starts up okay and then maybe keep the battery unattached and charged up somewhere with maintenance until I need it to get to the appointment with the auto shop. That way, at least, it doesn't die again just sitting there. Fingers crossed it works well enough that I don't need a tow. I know for sure it's the 12v, though, because he tested the battery before putting it on charge and it was completely dead.

    A charged 12v battery should last three or four weeks in a Prius and still start the car.

    1. A bad battery can sometimes hold a charge for a few days and still work. This can be verified as the cause with the easy and free load check process at any auto supply and most shops. Once diagnosed, a new battery "may" solve the problem. At minimum you know you have a bad battery.

    2. However an excessive parasitic draw can drain a good or a bad battery. Both are drained but a good battery can be recharged and pass the load test above. A parasitic draw is from the vehicle and not the battery. You buy a new battery and still have a parasitic draw and the new battery will also discharge in days. A shop can verify parasitic draw and possibly save the cost of replacing an existing good battery.

    3. A bad connection can act like a bad battery and cause an unnecessary replacement. Usually the direct battery terminals are loose or the battery ground cable connection at the chassis are connection problems.

    If the above is not checked, $250 for a new battery may or may not fix it. Finally, you just bought this car from Carvana. If true, you have a short time to get a remedy. The problem could be bigger than a battery.

    Yeah, at this point, it's probably better to just let the shop figure out which of these things is the real issue. I'm sure maintenance at my job can help with some little things, but at the least, with the shop, I have a decent chance that Carvana's warranty will cover the cost of repairs. Hopefully, whatever the issue is, it's not going to be super expensive to fix, just in case they don't cover it.

    Typically they won't cover a wear item like a battery past their 7 day money back warranty. I believe they will cover a tow up to $75 within the standard 100 day 4k mile limited warranty. Some car insurance policies cover towing as well.

    Try the recharged battery and then go from there. Ask your maintenance guy if he knows how to do a parasitic load test. Assuming it starts, drive to an auto supply for a load check. Call nearby dealers first for their best price on a Toyota 12v battery before buying an auto supply battery.

    If it started after the recharge, that is a good sign but it also means the battery was severely discharged when the earlier jump start failed. Lights that go away are fine. Any that stay on are important to know about.

    Ace Hardware is not an Auto Supply or a shop. However they should be able to tell you where an Auto Supply can be found. As can google "auto supply near me."

    You REALLY need to drive this car, there are plenty of potential expensive problems with this model. You have a short time to exercise the Carvana warranty, don't blow it by not driving it at least every other day for a few weeks. You need to know what the issues are.

    Believe me, the gas cost is peanuts compared to a $2,500 brake booster, a $3,500 dealer head gasket job or a $2,000 high voltage battery. Those are just the common gen3 issues that the owner pays for when they fail. If someone used head gasket sealer it will only wear off through driving. That problem can cost more than all the above combined if the engine fails.

    Well, there is definitely a parasitic drain on the battery somewhere because it was completely dead again after barely 2 days, and they tested the battery when they charged it, so I don't think the battery is bad yet (might be headed that direction after all this). Hopefully, the lights are all tied to whatever the issue is with all of that. I've got an appointment with a shop in just over a week, so I'll just have a professional take a look at all of it and find out what the problems are. It's better than struggling to figure all this out on my own, at least, even as helpful as everyone here has been.

    A parasitic drain test is pretty simple. Normal off state draw is around 25 ma. Finding the problem, if it exists, can sometimes be tricky. Common issues are the hatch light staying on (no auto off timer), map lights manually turned on and left on (bypasses the timer), aftermarket electronics, obd2 readers or anything left in the obd2 port. We have seen expensive parasitic draws as well such as the power steering drawing continuous power.

    I could offer a drawing on how to do a parasitic draw but it may be beyond your experience level at the moment.

    On the other hand, it is possible for a marginal 12v battery to charge and start the system but discharge quickly because the battery capacity is gone. With a simple charge you really don't know. A load test at the auto supply or shop is more definitive.

    Bottom line it could still be the12v battery.

    As it turns out, there's nothing wrong with the car or the battery. Apparently, the driver who dropped it off left an internal light on that I didn't see the 2 times I'd driven it (hard to see lights like that in broad daylight when that's not what you're looking for), and that's what was killing the battery. It's at the shop now because I'm not able to go get it at the moment, but they did all the basic tests for the battery and the parasitic draw thing and everything came back good. So, nothing is actually wrong with the car; I'm just too blind to see the light someone else left on just above my head.

    i would consider that a parasitic drain :cool:

    i'm glad it turned out to be something simple!(y)

    Honestly, I talked to the people at the shop today, and the hybrid battery is going out. I'm not sure of all the details because I don't understand shop talk well enough to remember and repeat it, but he's going to try to get Carvana to cover it while the car is still under warranty.

    I just find it amazing how this worked out, though, because without this specific visit to the shop, there's no guarantee the issue would have been noticed in time to be fixed under warranty, and hybrid batteries are expensive. I just wonder how differently everything would have gone in any other situation.

    Funny, I got the car back on Wednesday, and he said the battery is good, just that it might have gotten low from sitting for a little while before it made it's way to me. Didn't actually need to replace it, or anything. And even though upon dropping off the car, I mentioned the warning lights that were appearing on the dash only when I started it up, nothing more was said on that matter, nothing was checked specifically in regards to the lights, and they're still going off when I start the car, even now. Hell, last night, the overhead push light came on all by itself (I know this for sure because it was off a few minutes earlier and it had been putting stuff into the back when I came back with another handful of stuff and saw the light on), and I sent him an email earlier (calling wasn't working today) explaining everything I'd noticed (I'm one of those people who is oddly good with details, and it feels connected somehow; I checked the oil yesterday and it's clearly been serviced somewhat recently) and all he says in response is that he can do another scan for me if I want some "peace of mind", and it just rubbed me the wrong way. Like he doesn't believe me, or something. I know for sure that the brake and abs light were part of the circuit coming on, but the others disappeared too quickly for me to recognize them. The warning lights appearing upon startup and an overhead light coming on all by itself? That seems like something to me.

    Edit: I'm even starting to wonder if that's what caused the whole issue in the first place, if the light came on all by itself and killed my battery. Could be why I never noticed the light, in the first place.

    Edit02: I feel kinda stupid. My coworkers told me that the warning lights coming on when you start the car is normal, so now I know that particular issue is actually nothing. Granted, the overhead light coming on all by itself is definitely something. It's probably what's been killing my battery, either a bad fuse or a short somewhere in the wiring, according to another coworker of mine who actually does know cars.

    All of the lights on the dash are supposed to come on briefly when you first turn the car on and then go off. If none stay on after a few seconds then there likely isn't any codes stored for a scan to find. The dome light coming on by itself does sound kind of weird.

    The dome light could just be a weak switch. Mine is easy to move and easily gets stuck
    between notches.
    And as JSB_99 said, all those lights are supposed to come on when you first start the car.
    If they all go out within5 seconds, everything is good to go! (y)
