Dubious Frame Cracks

Here's a crack on the down tube of a carbon fiber composite Cannondale System Six, noted by the user after 3 months of regular riding. The clear coat is surprisingly intact. Cannondale agrees with the user's dealer, concluding that it resulted from a crash. A crack without damage to the clear coat is dubious. It seems to me to be a fault during manufacturing or packaging.

One can see the crack in good lighting.

Here's another 'crack' in the top tube of a Scott Addict Limited 2007. Again, the clear coat is in near to perfect condition. It almost looks like a cosmetic flaw to me, but with carbon fiber, you can't take any chances.

Both sound like warranty issues and should be communicated with the dealer, or the bicycle company itself.
