New 2026 KIA Carnival V6 EX Crackling Noise: Normal or Lemon?

My new KIA Carnival EX with 500 miles makes soft crackling sounds after turning off the engine similar to the video linked: https://youtu.be/_xmEYNpfBkw?si=cmhBRnugEw1qRcDT

Do any other V6 owners experience these sounds? This happens regardless of whether it is a short drive or longer drive, in temperatures ranging from 30-60 degrees Fahrenheit. I do not push the engine hard.

It seems these sounds are normal when parts are cooling down in some vehicles. But I was surprised to hear these sounds in my brand new van, especially on shorter drives in mild temperatures.
