It's blown or contains a manufacturer's defect. If you've never overpowered it (and they'll be able to tell...) call MTX or your local dealer, and have them RMA or replace it.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
