It didn't happen to me, but of the 4 people in direct team that had them, 2 had battery issues where the battery expanded making the laptop unusable. *Edit: This was covered under warranty, thankfully
This is from approximately 2 years of daily use for work. I no longer use my surface.
I typically care for my laptops very diligently. I still use my MBP from 2012 and it works like a champ. I don't have a windows laptop anymore, but my main desktop is windows. I'm not a Mac fanboy.
