There was a recall on last year's to replace a cracked fuel bladder (not the main tank). I'm told the old ones didn't have afoam rubber mounting.
There was also a fix for the 3pt lift on some early BX's to change the attachment geometry a bit. Not a recall but a free upgrade is available. You'll find the affected S/Ns in a scanned image of the change order online here.
You'll find more details on these in the archives.
