    Hello everyone,

    I've been reading posts on here for the past week and have found them very helpful, but wanted to get very specific with my questions.

    I am wanting to purchase a used Prius v (we want a hybrid but have two kids so need the extra space). These cars seem to be going for insane prices right now (like many used cars). I am looking at a 2014 Prius v Five with 130k miles listed for $12,300. It has had two owners and both of them serviced it at the toyota dealerships from which they purchased the car (26 service records on carfax). It is $2k below car fax suggested price and significantly below many other similar cars listed. Seems like a great deal (for reference, there is a 2012 Prius v two with only 10k fewer miles listed for $18k).

    But when I test drove the engine has a misfire (which I have now heavily researched on this forum). The owner popped the hood and said he hadn't had a chance to have his mechanic take a look, but it must be the spark plugs or coils. They run the codes and it is showing multiple cylinder misfire codes. He says he can tell the spark plug / coil on the first cylinder has already been replaced, and says he will have his mechanic replace the others that day. I didn't think much of it at the time, but he also refilled the coolant (now realizing this is a sign of head gasket issue?).

    I almost walk off and continue my search, but I had made the trip to see it so I ask to take the car to a mechanic shop to take a look. I make the mistake of taking it to the Toyota dealership. They say they want $300 to do a 2-hour diagnostic and I say no thank you. But I talk to the guy about the situation. I say I am worried about a larger problem and he says that if no engine light, the problem is probably not going to cost me in the 1000s of dollars. This gives me some comfort, as I am okay with repair work as long as it is not complete engine failure or something.

    I decide to do more research over lunch (while they are replacing coils and spark plugs). Reading on this forum, it confirms that spark plugs and coils are often the problem, which gives comfort. When I go back, however, the problem is not fixed despite all new coils and plugs. I talk to the owner. he agrees to have his mechanic work on the car until the problem is fixed, but will need a deposit to hold it for me. Says it will be refundable if not fixed by a certain time and if it needs more expensive work I'll have the choice to do it or walk away.

    I was okay with this at the time because (a) the sales guy had already agreed to come down $500 off the price due to the issue and (b) I figured even if I spend $2000-4000+ post purchase to repair the car, I'll still be no worse off vs. what else is on the market (c) I am happy to invest the money if this car could take me to 200-250k+ mileage

    Dealership is now saying injectors were replaced and no more issue, but I'm now reading more about the issue and worried that at this many miles if it has had a carbon buildup issue for a while, the head gasket will need to be replaced. I think that might still be within my budget, but (a) I am not sure it is worth the hassle and (b) I am worried there could be other problems.

    From reading other posts, I know you all will likely recommend I pass and buy a new car (rightly so). But more helpful feedback would be (a) how likely do you think that I need to replace the head gasket, (b) how much will this cost, and (c) what other serious potential issues should I be factoring in and (d) if I buy this for $12k and put $2-5k into it, what is the likelihood that it lasts another 100k miles?

    At this point, I am considering walking away and losing my deposit and getting a newer car, although to get an adequate alternative I am likely going to need to spend $20-25k which is a significant jump in price so just trying to weigh my options.

    Thanks!

    welcome!

    is it a toyota dealership, or corner criminally owned used car shyster?

    because these cars are prone to the head gasket issue, it could be a real risk, and you might even need a replacement engine.but there's just no way to know without a full diagnosis.

    and don't forget the $2,500. not in stock brake actuator.

    another 2014 question is if you have the old or new pistons and rings, which were upgraded mid course.

    why would they be selling it so cheap, if they thought the head gasket was not the problem?

    It is a corner criminally owned used car shyster for sure. I agree with you on the price. I think part of how i rationalized it is that it is only a bit under the KBB or carfax "fair value" but the issue is that there are a bunch of others that are significantly over "fair value" on the market, so it is cheap relative to alternatives. The sales guy definitely didn't know what these were going for elsewhere, I know that.

    Thank you. I think I am probably going to pass, and likely need to get something other than a prius, unfortunately.

    it is strange to me that it had such a strong maintenance record at toyota dealerships and this was never caught / addressed...

    No engine light is common with hg issues. So he was either misinformed or lying.

    Changing plugs, coils and injectors does not hide or excuse the smoking gun... loss of coolant. I have run for many years without ever adding coolant and this car should too unless its causing the misfires.

    There is a $20 temporary fix for coolant leaking into the cylinder. Flippers all know it. Stop leak. Lasts for several weeks or months but the root cause returns with a vengeance. Sometimes with a hole in the block.

    Run.

    Thank you. This is all very helpful. There were just so many little things that had me convinced it wasn't a terrible idea but reading through more on this forum today and realizing the coolant was a big red flag for HG issue was what scared me. They also tried to sell me on the warranty and i asked it it would cover the HG and he said probably not because they don't cover carbon build up issues. so putting all the pieces together now and grateful for this forum for saving me on this one.

    Back to the drawing board.

    If I were to consider a regular prius, what year(s) should I avoid?

    Well, it wasn’t on the v Five, but a can of Barr’s Leaks stopped a Dodge Grand Caravan V6 rear bank cylinder head leak (external) for more than 100,000 miles and a dozen years, until the car was stolen.

    3rd gen Prius (and the Prius v is similar under the hood) are prone to head gasket failure. A newly minted EGR system is prone to carbon clogging, and leads to head gasket failures, anywhere between 100~200K, typically starting and cylinder one, and involving coolant leaking into the cylinders.

    Connecting the dots?

    Yes, grateful for this forum for helping me connect the dots.

    I am just about to talk to the owner of the dealership to try to get my deposit back (fairly low likelihood, but worth a try). They have their own mechanic and do some repairs themselves. They've already replaced all the coils and plugs, fuel injectors and are now replacing the EGR system (what the sales guy said, need to confirm). I don't think they would have the ability to replace the HG themselves, but he may offer to split the cost of that at another shop. Is there any other potential repair that this would need due to this issue which I could use as a negotiating chip?

    Thanks,
    Justin

    there is a total egr circuit including the intake manifold which needs cleaning. it can't be done lazily, but it is not difficult for someone who cares and pays special attention.

    you can find directions @NutzAboutBolts youtube channel

    idk if there is any possibility of other engine damage, if it has ever overheated due to lack of coolant.

    as far as what prius to buy, high gas prices are the only time they are valuable, which has been rare over the last decade.
    some 2014's and all 2015's got new pistons and rings. whether that solves the head gasket problem remains to be seen.
    2016 is a new generation, and the major problem has been coolant leak in the exhaust system.

    i don't think we have a handle on the quantity of cars yet. i would read through those threads if you consider one.

    You know they were aware of the misfires and coolant loss before they sold it to you. They know their markup is huge as they have been willing to do a thousand dollars worth of minor maintenance so far. Plus 90% certainty they have used sealant. My guess for the second time. The first time did not last long enough for a thirty day warranty.

    Now they are hoping you will be satisfied with an egr valve. Guarantee you won't get an egr cooler or intake removal and cleaning or replacement. I also guarantee they knew about the coolant loss from the beginning and now know a head gasket/engine is a real possibility very soon. After the tail light warranty expires.

    I suspect NY consumer protections are the only reason you are still hearing from them. Run.

    Yes. For anything they miss (say the intake, see first link in my signature.

    Linked in my sig.

    To OP: I still would suspect head gasket is already failing, as evidenced by mileage, coolant loss and the fiact they previously replaced cyl one coil/plug. The latter was likely knee-jerk response to cyl one misfire code P0301 (classic 3rd gen head gasket failure symptom).

    If the HG is failing, all the EGR cleaning they're offering (while always as good idea) is currently "closing the barn door after the horses have bolted".

    I would concentrate on refund.
