I have read quite a bit on this forum, but never posted. I am not knowledgeable about car mechanics outside of the basics. I thought it may be good to document my experience here, as I have used the postings of others. I have never had a car remotely like this one in any aspect.....power, technology, you name it. To say that I have enjoyed it is an understatement. I drive it pretty hard, but it has always had premium and all the servicing and oil changes down at the dealership. I run 4 gals of E85 with the 93 oct as often as I can, which typically means about a tank out of every third. The majority of my driving is long distance as I use my car for work trips. I got both the extended warranty with premier plus wrap roadside, and the rim and tire protection. I did not want to have to worry about having a reliable ride for work and for taking my daughter to her weekly chemo treatments ALL B Cell.

Last Sunday, I was stopping the gas down on my 2020 RWD GT 2 with about 13K miles on it, and I hear this odd noise, feel a big loss of power, and white smoke comes billowing out of the exhaust. I seriously nearly threw up. I limped back to the house looking like a fog machine. It smelled strongly of burnt oil. At the time, I was running Map 4 with 93 octane and E85. I was not running a log. Previously, I collected several logs but never got around to posting them or learning to read them.

At home, when I was taking my mods off, I noticed that there was a splash of oil below the intake on the left as you face the front of the car. When I took that intake off, there was quite a bit of oil inside the intake hose. The oil was about a quart low. After returning the car to stock, I could kill the car, and it would crank again fine. It idled kind of rough and smoked its ass off. After a while of running the smoke eased off a bit. The CEL was on and there was a message about the ECU having a problem.

Very shortly after all this happening, I had to leave for a long drive to a work site for which I had to get a rental. I was very busy at the work site, but I managed to get my roadside coverage to tow the car to the local dealership. After several days when the service department could look at it, one of my friends got in touch with them. "They said that there was an engine failure and oil had gotten into the turbo's. The engine and the turbo's would need to be replaced." When my friend asked what caused it, they said, "It was nothing that was done. It just had a failure. It would be fully covered."

The problem is that he said that there were also other Kia cars there that were waiting on an engine replacement that had been waiting since November. They were backed up and having a lot of trouble getting the engines from Kia. Maybe because I live in the southern US and the Winter Storm Uri was like a mini apocalypse and shipping is very screwed up. They had no loaners. They did mention that rental cars were covered as a part of the warranty. I'm currently trying to figure that out.

On a personal note, it could not have come at a worse time. It was my only car. Besides using it for work, my daughter's leukemia relapsed and she went back into St. Jude's which is 4 hours away. Due to covid restrictions, I have not been able to see them since she was admitted three weeks ago. I have been waiting for my chance to get up there as soon as she is able to be outpatient. Needless to say, I am busy trying to obtain a ride until whatever time I can get my car back.

I will post updates.
 
I think the stinger is not designed to run e85 or even e30 as it does not have a flex senor built in. I have heard people run e30 using a jb4, but not in an untuned engine.

What did the dealer say that caused the engine failure?
 
Holy, crap. What a saga, and for a first post as well. I hope that as things have been rapidly improving you will get a spanking new engine soon. Everything should be fine after that. (I send a prayer your way, sir, daddy, worried and grieving: leukemia; could news be any worse?)

Sorry to hear about your vehicle but most important, your daughter. Hope things turn out well for her sake. I too had to have engine replaced and it took over a month. COVID held things up quite a bit. The dealer did eventually get things fixed and new motor runs better than the new one.

Unfortunately, you are at their mercy and there is probably not much they can do about the "logistics" so I would say do what you can to stay on top of the situation but stay vigilant for your daughter.

Billowing white smoke, loss of power & CEL as described are the symptoms of a blown turbo. Must have thereafter done further damage since they've decided to replace the whole motor. Should not have anything to do with E30 mix.

I doubt it’s the turbo‘s. Likely, piston failure from a detonation event.

What mods did you have and what spark plugs.

Also, if your car is down for a while, such as months, get them to re-imburse you for car payments if it is financed.

Technically 30+ days can be a lemon law... get a refund... or have them swap to a new Stinger... :ninja:
 
It wouldn't be fair to push for a refund, buy back or lemon law if you have ever put any mods on the car as it's the risk you took by doing mods. If your dealer is going to replace your engine under warranty without the hassle of determining if mods were at fault then basically you will be made whole again and that seems very fair. The dealer will usually have a rental car company they work with that will provide you with a rental for the duration, so again you will basically be made whole. No dealer will pay for your car payment while it's down because it's not fair to owners who paid cash and it's not fair to dealers if you are upside down with a ridiculously high car payment - and that is what the rental car is for. I would usually pay the rental car company for full insurance so I don't have to bother with my own insurance, but if your car is going to be out of service long enough that the cost of extra insurance will likely be more than your own insurance deductible then don't pay for it and rely on your own insurance. An engine replacement will likely take longer than a month - took two months for mine. As monusa has experienced either they reserve better tested engines for replacements or the dealers take the time to install and tune them better, but my engine is running 1000% better than the original engine I had so I think you will be very happy with the car when you get it back.

Yep...to all the above. I have to agree, the replacement is putting out boost levels akin to running jb4 on map1. Response not as immediate but logs were showing nearly 4psi above what the original engine was doing. It was a pain in the butt when they replaced mine so I know it is the same for you.

The dealer hasn't said anything at all about reimbursing for a rental. They just told me that their two loaners are out to the two people waiting before me since November to get an engine swap.

They mentioned that Kia should cover it under the warranty, but I believe that would be entire up to them. I have yet to be able to get in touch with them since they are closed during the weekend. I did manage to get a case number online.

How exactly would a dealer (or anyone else) determine the mods being at fault? The mods and how they were run was not exactly pushing it.

I just had my motor replaced too. Took 4 months over the holidays. But glad to have it back and there is something to be said about the new motor compared to original. Just got the breakin period over so did a dragy run and fully stock awd gt2 did 4.52 0-60 on first and only run. I was already very inclined to keep it stock due to hell of engine replacement so the better than expected performance has made it a sure thing.

Just....wow
 
If the dealer is going to cover it under warranty, I would do what I needed to do to get transportation until the work was completed. I still had to cover my payment even though I didn't have the car but since it was covered under warranty, I was NOT about to "cut off my nose to spite my face" and mess up my credit by not making the payment.

I TOTALLY get not having the ride but if Kia is going to foot the bill, be somewhat thankful.

Ditto.
 
1. Mods his only DD
2. Runs an E85 mix at a more than mild map
3. Doesnt log or learn to read logs
4. Needs car reliable to take daughter to freaking chemo treatments


WTFFFFFFF is going on no way this is real

Oh yes, definitely. This is my plan, and I agree in everyway.

I wish it were not real. There are lots of things and people that I wish were not real, but if wishes were horses then I'd be able to just ride that.

I read as much as I possibly could, much of it on this forum, before I did anything. I formed the conclusion that what I was doing had some risk as most things do, but my perception was that it was minimal. Obviously, I am not immune to confirmation biases, but I believed that I was forming my opinion from countless instances of postings from others. Many times, I found myself reading about the engine being "bullet proof" and more than capable to handle much more than just what I was doing.

I have no idea if the after market intake, E85 mixture, or JB4 settings may have caused this or not. Do you think that was likely? From a technical point of view, could you give some theories?

1. Mods his only DD
We have another car in our household. My wife's. It is a 2015 Ford Taurus that is in great shape. Unfortunately, it is in Memphis with my wife and daughter at St. Jude's. Normally, it would be here as a back up.

Risk assessment is historically an extremely hard thing to communicate properly. So that I understand, you are saying that a person should not mod their DD with mechanically related mods at all?

2. Runs an E85 mix at a more than mild map
Other than some longer term damage when used often, how could the mix have contributed? Is Map 4 considered aggressive?

3. Doesnt log or learn to read logs
I definitely should have, but I never had it run funny nor have a CEL come on. In terms learning myself, I just don't have the time with my personal life, working long hours, and going to school online.

4. Needs car reliable to take daughter to freaking chemo treatments
Yes. I suppose here again you are insinuating that I took excessive risk while I genuinely did not gather that was the case. I am acutely aware of the difference between foresight and hindsight, whether it be with me or someone else. Are you?

In hindsight, I feel bad at the possibility that I may have caused this. Hopefully, more information will come out that could help shed light on it. If anything, I am happy to come forward and tell the story if only for the benefit of possibly helping others. This is regardless if I look like the biggest dumb ass in the world or not. I'm not interested in judgements.

Thanks for your response. I would love to hear your thoughts and opinions laid out. The best thing about a bad situation is the ability to learn from it.

Only map 1 or 2 can be considered mild because they only require pump gas. Map 4 on the JB4 site literally says: Map 4: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%. Yes thats more than a mild type of tune especially if you are not monitoring the amount of E85 in the tank, just estimating it during fill ups is not exact enough. Having the wrong fuel on an aggressive map can certainly cause engine damage and fast

You dont need a CEL to come on to do damage to your engine. JB4 logging exists to catch issues before they happen

Im not saying not to mod your DD. Im saying there is a difference between knowing what you are doing, and closing your eyes and hoping for the best. At least if youre going to close your eyes, walk slowly instead of running. You can do a map 1 or 2 tune on the JB4 and be almost guaranteed never to run into an issue as long as you regap and replace plugs (along with logging). Learning how to take logs is part of tuning, you cant be too busy to do it. All you have to do is post them here, tons of people do that and other people will read them for you

Look I dont want to shit on you when you already feel shitty. Ive made some stupid decisions too in my life, just havent posted them in a public forum. It take guts what youve done, I commend you for committing to learning from this.

I will not judge anymore. I and other people in this forum can point you toward links, posts, etc that might help you out for this car when you get it back or future cars. Just ask away
 
Side note: this is a hell of an endorsement for the JB4 being undetectable by the dealer...
 
The dealer is going to need to know about the E85 in the tank, at the very least they'll probably need/want to drain all the gas out of it(?).

**edit -- actually, it might not matter. 93 octane with E85 is a potentially higher octane blend, depends on the percentage of Ethanol mixed. Certainly won't have any pre-detonation issues. Wonder how high octane the default Kia mapping adjusts?
