I had this happen to my 2013. Warranty expired 05/2017, bubbles started 08/2017, so I chose to ignore it. Adhesive eventually began leaking out which was very annoying because it is so difficult to clean. This year in 05/2019 I was fed up with all the adhesive leaking out so decided to finally pay for a new screen.
Prior to my service appointment, I took out the cubby to clean the adhesive and found about 1/4 cup of adhesive, way worse than the photo upthread. It was a huge pain to clean it out.
I got the new screen and thought all was good. Now it's 90 degrees here, and more adhesive than ever is leaking out, worse than before. Adhesive from the old screen had collected somewhere else inside the dash where I can't see, and it is leaking out again with no end in sight. And I can't clean it because I don't know where it's coming from, and don't know how to disassemble the dashboard. It is very irritating.
I caution anyone with these bubbles against waiting too long for a replacement, as a lot of adhesive may leak out and collect where you can't see, which will be very irritating later on.
