2023 Cadillac CT5 BW
Hi everyone, finally got my 5BW and the car has 1700 miles now and the car does not disappoint. Recently I notice there's a squeaking noise (or whining? I'm not quite sure but some kind of high pitch noise) when pulling away from a stop. It happens both when clutching out at first gear, or throttle at low RPM in other gears as well. Not at idle or cruising. I'm not super positive at higher gears due to wind noises muffling it. It happens both at start up or when the car is warm. Now that I think about it, it's not a new noise but I haven't registered it until recently, since I mostly drive it at night now when it's quiet outside.

The noise itself doesn't bother me too much but is noticeable even with window up. I'm just worried if there's any underlying issue I should address. Does this happen to anyone else?

I posted a thread on a similar sounding issue, but I have a 4BW. Does it sound like any of the videos I shared? The post can be found here:

It could be drive belt / pulley noise
Yeah it could be. Same with OP, I noticed it only happens when the car is warm. I’ll have the dealership take a peek when I get my first oil change done. My car is brand new, less than 1k miles.
 
Bumping this. Same thing happening to me. Anyone else?
