On my second M5 and haven't had that happen on either.

The reason leather cracks is if you don't moisturize it frequently enough. You need to moisturize monthly in winter. If you don't it dries and then cracks. Cracks are caused by dryness.

At this point, you can still moisturize it to prevent it getting worse. I have heard that Swissvax elephant leather wax can help cracked leather but I have never had reason to try this myself.
