New Baitrunner problems!

[Rockport24]

So I've had a BR6000D for a couple of years, last year at Cuttyhunk it got buried with sand (when I flipped the yak on a surf landing because I was so shocked at seeing skinny dipping babes) but Martha at surfland cleaned it out great and it worked flawlessley for the rest of the season.
Well this year, I hook a schoolie and the drag just lets go completely, no drag whatsoever.
Martha fixed it, but said she has seen a lot of issues with the new design, something about the way the bait runner drag disengages... Took it out last weekend and the same thing happened! Sending back to Shimano now.

this is a real dissapointment as it was really a great reel and worked awesome for live lining macks off the kayak. Anybody else have any issues or did I just get a lemon (or maybe the sand really did have a lasting effect). It's just the old version seemed to be very durable, so I'm kinda pissed about this..
