I have a '16 with ceramics....I just swapped out the rear pads at 10K miles. Not happy about it. I hope this isn't the normal, and I hope you get more than just 15K or so.

 

I have almost 50K on my 2012 and still have a little less than half of the pads.........if that helps.

 

Mileage is not much of a determining factor when it comes to brake wear. I'd say it's more about a person's driving habits (how heavily you accelerate and how hard you apply the brakes; some people get on their gas hard only to stomp on their brakes at the end of the block), where the driving is done (highway vs local st) and even traffic (more stop and go = more wear overall on your car).

 

That's not too bad.
