Re: '07 Mazda3 driver side door lock issue...
Not to speak for the OP, but I don't think that's the point. I never use the manual lock button, but putting myself in the OP's shoes for a minute, if this were me it would be a minor annoyance--one that I may be inclined to get fixed if I can still get it fixed for free. What if it gets worse, breaks, or just stops working altogether after the warranty is up? Then I'd be kicking myself for at least not getting it looked at while it was under warranty.
Again, seems like a very minor annoyance, but it sucks when stuff doesn't work right on something you spend (a lot of) your hard-earned money on.
