Is anyone else having trouble with Spinergy X-Aeros?

I bought a Caliente in June that came with them. A few weeks later a couple of rear spokes loosened to the point of rattling. It apparently happened while it was just sitting in the house, as all was fine on the previous ride. The dealer re-tuned the wheel for me.

I found the same situation again last night, and the wheel wouldn't rotate without sticking on the brake pad. When I tried to tighten the spoke enough to use it on the trainer this morning, it just pulled out of the hub.

I'm waiting for a reply to my e-mail to the dealer, but for now i don't like the idea of taking those things out on the road.
