2.0T Stuttering issue when coming to a stop in the cold 2020 kia stinger gt-line 2.0

[Duckworth1214]

I recently purchased my stinger in June, I have noticed that after it has been sitting for awhile in the cold (either in the morning or after working all day) if I don't let it warm up for 5ish minutes or so, whenever I drive and then have to slow down for a stop or such, the car stutters and almost feels like its trying to die. It only does it after sitting in the cold for extended periods of time and after a few minutes of driving the issue goes away. I've read about a variety of issues it could be, I recently had the spark plugs replaced with normal maintenance, as well as fuel induction service done. Is there a bigger issue going on that needs addressed or can the issue just be resolved by just letting the car warm up a little longer on cold days?

Also have no codes or lights popping up so hard to narrow down to exactly what could be causing said issue.

No CEL, you say, so, it could be early issue with one or more coil packs. Changing plugs won't help, and in fact will be wasted hassle and money as a bad coil pack will destroy any plug in a matter of days. If you try engaging the turbo boost you will likely start seeing the CEL come on.

Alrighty, I will give that a try and see if it pops a code!

Update could not get CEL to come on, but earlier today after my car was sitting for about 6 hours in the cold it had trouble turning over trying to start it. Scheduled an appointment with the local kia dealership on Monday. Read that it could be the coil packs as suggested, or possibly a sensor or issue with fuel system, which I believe is unlikely since I just had a fuel induction service done less than 2 weeks ago, also battery was tested then and stated to be in "good" condition.
