Hi! I've noticed this problem on my low mileage 2021 SS 1LE. When I start from a stop, particular in 2nd, I hear a short squeaking/squealing sound. I can also identify this when going at low speed in 1st and accelerating slightly. I do not hear any sound when the engine ISN'T under load, so I'm not sure if it's a transmission/clutch issue or a sound that might just be exaggerated when the car is under load. It's not a horribly concerning sound, but it is weird enough that I figured I would ask.
You can hear it fairly clearly at about 4 seconds in this video. I sat in the passenger seat with my phone out the window and my copilot started slowly in second, which is where the noise seems to be most prevalent.

For whatever it's worth I swear I hear the same sound when I start it up in a garage after sitting for a day or two. Not sure if it's some sort of timing thing related to a cold engine/lugging or what.
Any help would be appreciated!
