This is the first video I could find after a lot of research, that shows the exact "problem" and sound that I have with my MBA M3 13". Every time I open it, its like this but if I open it once, then close it and immediately open it again, then the MacBook opens as it should, which means that there is no real defect.
My MBA also has a slight gap on the left side between lid/rubber and the bottom part of the MacBook case. When the lid is closed, the gap can be closed or reduced by applying light pressure with your finger. But the gap looks significantly thinner to me compared to what I've seen in pictures of other MacBooks, so its probably in tolerance and no real problem.
I got this MacBook from Apple Certified Refurbished one month ago and it's working perfectly fine. (It's probably a returned unit and the pre-owner didn't want to live with the gap and opening-sound. 🤣) But that's no deal-breaker for me, I just was unsure about how this problems will affect longevity of the MacBook.
It seems like this problems are very common and I even read that people had to request multiple replacements until they got a perfect unit and that's definitely not the way I want to go. I will get AC+ to be safe (even when the terms here in Germany say, that damages caused by design defects are not covered 🤨) and just use my MacBook without any worries from now on.
