Well, we took the plunge and bought a 21 with 15k on the clock after a couple weeks of getting used to this car it has become quite apparent that

most people trash these cars and then dump them when they stop running correctly. We did not go into this without this info blindly thanks to

youtube and other social media outlets. However, there is a silver lining thanks to the Lambda platform and it appears that we may have found a diamond

in the rough so to speak. So, after a couple of weeks of driving, we changed the air filters (noticeable difference) and holy crap, they are the same

ones that came from the factory. So, next step is to get the plugs changed since this whole engine platform is a intercooled turbo set up and when

the plugs become gapped out of spec the can turbo blows out the spark which in turn causes stumbling when the motor is under full acceleration.

I would like to know if anybody has the stumble issue.
 
"Holy crap", does that mean that you don't want to return the engine to stock? I know this. Modded cars frequently complain about "stumbling", aka stuttering, misfiring, etc. Bu.t even stock cars can get it. Plugs and coil packs are the first place to look. Don't put in new plug or plugs without thoroughly checking the condition of the coil packs. A bad one will just crack each plug that you put in, usually within days. My engine is stock but had this issue at one point.

Thanks for your response. I had all the plugs replaced and it runs fine now. This car will never be modded and will

always remain stock. These motors are good but the battle is carbon, and fuel into the oil if you don't take care of them.

I feel like I probably should do the maintenance on it when needed because if you ignore it then more problems will crop up.

It has a warranty, but I don't think the previous owners took care of the things that should have been addressed when the time

came. The car is basically new and it almost feels like the previous owner just flogged the crap out of it and then traded it in.

Time will tell, but I think this will be a fun cruiser and fun to look at with the orange paint.

Btw 7.29 quarts of OIL... wow
 
Fed Orange, my favorite color. I've seen one exactly twice in over six years. Curious, the GTS, only 800 of them in the US, came out in 2019. I thought that the next year a special edition GT2 was issued in Fed Orange, but nothing after that. You say "2021" in Orange. Can you explain that please?

You can check the maintenance history, and if there isn't one, your concerns are probably legit. However, 15K miles isn't a lot of time to actually ruin an engine, as long as it didn't run out of oil or other fluids, which, on a brand new car, isn't likely unless something went wrong. Your probably good. Now, just maintain it like you've said. By the way, KIA uses Mobil full synthetic, so, look to see if there were any oil changes at the dealer during that time.

It's a Canadian import brought here by some tech guy who traded it in at a dealership here locally. Apparently, the Federation Orange color in the USA is called Neon Orange up there and was
able to be had in Gt2 trim.
 
On the color and trim level. This is a Canadian car. But in Canada, its called Neon Orange and it's the same

as the Federation Orange sold down here. I suspect we will see more orange Stingers going forward as it

is common for cars to be imported where I live. This car was offered in this color in the GT2 trim level up

there as far as I know. Thanks for the oil tip. BTW, the person who imported this car worked in tech and

traded this in on a Hyundai Elantra N Line.

you are seriously telling me you can tell the difference from an air filter with 15k on it? I changed mine last at 30k I believe and they looked brand new almost and made less than no difference performance wise.

How does a car "feel flogged"?
that's a serious question btw. Like what indication are you getting from what aspect of the cars operation make one feel flogged vs not flogged?
 
Yes I can when you can't even see thru the filter media when holding it up to the light. Flogged= Front brakes are nearly
gone and a misfire code which lead to a out of spec spark plug therfore causing the engine to stumble upon acacceleration. All after 15k.

You shouldn't have any real carbon buildup at 15k, and you can prevent it going forward with a catch can.

I haven't heard any particular problem with fuel in the oil on the Stinger (mine show literally zero in Blackstone reports)...are you just talking about turbo cars and blowby in general?

7.29 quarts is full capacity but you won't drain everything during an oil change. I'd recommend putting in about 5.5 and checking the level before adding 1/4-1/2 at at a time (I think my last change with filter needed <6.25qt).

Hey, thanks for the info I really appreciate the input from the forum and community. The info on the carbon was

a warning from a tech who owns a bi turbo Mercedes that he has had for over 110k. He is very intense and at the

same time aware of just how turbo cars work. I just think he doesn't want me to miss oil changes and the maintenance

they require. I appreciate his candor and I do not plan on this car to be a daily so I think just fixing the things that were

"flogged" are the main goal on this ride. Look, its a used car, and with that you will have issues. However, this not my

my first foray into this type of car (Turbo Fords and Mitsubishi's) and a member of this forum rtv900 seems to think I do

not what I am talking about and that's okay as I am just sharing my journey with this car with you all. We have always had

a passion for this vehicle and we thought that this was a good deal, so we bought it. All that said, there is little wiggle

room when a spark plug goes out of spec and the air filters are plugged so much that you can't see light thru

the filter media. This will cause the engine control to freak out as the mixture is going to be wrong and the turbo blows

out the spark on the plug because it is GAPPED out of spec. Also, the front brakes are at .30 after 15k tells me that maybe

it was a car that was used to demonstrate what the car could do. That is a bunch of brake wear at 15k but not a deal breaker.

Just get the brakes done. Anyways, I thought it would be a good idea to share our experiences on a forum so that we can

learn from each other and so that we can make Stinger ownership better for all us who have decided to drive one.

Thanks!

I simply asked what indication you are getting that something was "flogged" based on the cars operation.
I think that's a pretty relevant question considering you continue to assert that.
and you haven't answered it

no a loaded up air filter will not make the engine control freak out in any way. If it was ultra, ultra clogged it would simply act as a slight throttle. The MAF is long after the air filters and will correctly read intake air mass no matter how dirty they are.
Absolute worst case scenario they will slightly restrict top end max intake and you will be down maybe 10-20% peak power at peak rpm, and that would be the most extreme of the extreme like if the car was used solely in a concrete plant or something and loaded up with ultra fine particulate.
Despite air filters appearing dirty, they basically never actually affect performance in any meaningful way.

Thanks Thomby,
It does have a Catch Can. Thank you for mentioning that. Not sure when it was installed. It has a Mishimoto catch can.

This is a mates car down here... the colour certainly scrubs up nicely :thumbup:
