I have a 2013. Based on my experience, I'd check the bolts.
With all that I added to my bike in the first month or so, the only two bolts I didn't touch were the two rear subframe bolts. I lost the right side bolt sometime in the first 500 miles. Fortunately I had already put on my rear rack system, so the bike held together well enough without the bolt to get home. When I replaced the bolt, I also checked the left side bolt and it was a lot looser than I expected it would be. I put loctite on both bolts and torqued to spec and haven't had an issue over the last 17,000 miles.
I check all the bolts regularly now and haven't noticed any loosening since I applied loctite.
Just my experience.
