You mean could it be that it's caused by mechanical wear like the scoring I described above? For sure, certainly.
What bothers me about that isn't that it's a design flaw - all mechanical parts wear, and the part I mention specifically is replaceable. I don't even think it's likely to be the root cause. I'm sure it's a red herring - keep in mind, I'm reading from a source that tries to consider every possible cause of failure and provide a diagnostic path to determine if that's the issue.
What worries me about it is that if the diagnostic process gets to that point, it's going to be hellishly expensive
