A friend just had this happen to their M1 Air under warranty and Apple quoted him $400 for the repair claiming it was "accidental" damage, even though he didn't do anything to it, like the 50 pages of people who replied in the thread.
Wanted to make a quick PSA against purchasing one of these to save a few hundred bucks vs the M2 Air which hopefully won't have this problem, and possibly put some pressure on Apple to take care of their customers for what is clearly a widespread hardware defect.
