Bizarre sensory experience

Little background story. Bough my first ever MacBook in September of 2021. Was using it just fine, despite some issues like YouTube videos suddenly turning black and playback apps like QuickTime doing the same. Less than a month (2 weeks in I'd say) it just turned off completely no warnings like a battery running out or nothing and I was not able to turn it back on again. Went to an Apple authorised reseller and it turns out they had to change the whole motherboard or something. It worked fine after that. Not even a month has passed and another issue occurred - a red line across the screen appeared out of nowhere. Went to fix it again, they replaced the whole screen and other graphics cards or something. Just to be absolutely clear there was no physical damage that happened at all, the device was brand new not even a scratch on it.

What's happening now. I have happened to notice it makes an electrical buzzing sound if I slide my wrist on the MacBook side (wish I could explain it better). There is no such sound if it is not charging.

I have recorded this incident and have video proof of it, and could upload it if it would help anything. So my questions are - should I be concerned about being electrocuted when using it while it's plugged in? Is it possible to get a device replacement if it was bought in September 2021 due to the fact that it had to be fixed twice now? I live in Lithuania and it's practically impossible to get clear answers if I try to contact support.
