Hi, Shannon and the usual suspects are:
1. Spark plugs in bad condition or partially fouled.
2. Spark plug cables in bad condition and leaking check for spark leakage in the dark.
3. Spark plug gap too close or too wide.
4. Faulty ignition coil, module, and or sensor.
5. Battery nearly discharged.
6. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
7. Intermittent short circuit due to damaged wire insulation.
8. Dirty air filter
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, fuel pump and/or filter.
11. Old dead or bad fuel.
12. A faulty fuel pressure regulator.
13. Pinholes in the in-tank plastic convoluted tubing from the pressure regulator to the quick disconnect check valve.
14. Fuel tank vent system plugged.
15. The throttle body controls misadjusted.
16. Damaged throttle body or intake seals.
17. Clogged or faulty fuel injectors.
18. Loose, dirty, or corroded ignition module connector at crankcase.
19. Faulty TPS, MAP, CKP, O2, and/or CMP sensors.
20. Incorrect valve timing.
21. Weak or broken valve springs.
22. Damaged intake or exhaust valve.
23. The control module may be in limp mode.
24. Check for engine trouble codes.

It is still under warranty, if you are concerned have it inspected at a dealer. You can attempt to locate the source of the noise to see if you can locate the area. One of places to check is the fuel tank.
Click on the link for diagram. I couldn't get the whole diagram in one picture and make it readable. Is it just one window or all of them? There should be wiring harness on hinge side of driver door. Black wire with red tracer is voltage to master switch for power windows, goes hot with key on. the bottom black wire in diagram is chassis ground. You can use test light to check both voltage and ground.
The engine, the cooling system does not cope most likely. You need to check everything. Does the car temperature rise to how many degrees? Does this happen in summer or winter? I also have a Kia, I have not encountered this. I have wanted this car for a long time and I didn't have a small amount, I accidentally tried to bet on a football team https://mobilebetting-bd.com/ and won several times. This made it possible to purchase a car in the future.
When you say "won't turn over" do you mean that it will not crank or not start? If it does not crank then it is an electrical problem. Check the battery and connections to be sure they are clean and tight. If it cranks but will not start, then it could be a fuel problem. Hook up a fuel gauge to see how much pressure you have. Could be a filter or a fuel pump going out.
