All US tanks are prone to warping and bubbling, possibly due to ethanol in our gasoline. Ducati is working on a new tank, rumors that these are now being shipped. No reported problem on bikes outside US.

This may be a separate issue, but my dealer seems to think the reason this happens on U.S. bikes specifically is because of the EVAP canister.

Your dealer is misinformed. None of us has been running with the evaporative can since we bought the bikes new. I just ordered my fifth GT tank, not even 3,000 miles, all w/o a can.
