I had a binding separation on my guitar 2-3 years ago repaired under warranty.

First, the repair was totally invisible and the luthier polished the whole guitar it seemed so it looked brand new. He is an authorized Martin repairman and only commented that cocobolo is comparatively hard to glue, nothing about a binding problem.

Second, and most importantly, Martin is making A LOT of guitars, so it stands to reason there may be more repairs to do. There are also literally thousands of their guitars with no problems. I think a luthier mentioning that he has had several (more than before) problems with bindings is as likely to mean there are more Martin guitars being made today as that there is a problem.

I don't hold it against Martin that my binding came loose. They repaired it. It's a great guitar.
