Interesting thought on overheating. I can be riding without issue, switch to turbo and get the cut-out issue, and then switch back and have no problem anymore. I wouldn't think it the temperature would fluctuate enough in that span of time but maybe.
It hasn't been enough of an issue yet...
I have about 200 miles on my Carbon Comp. It does the same thing but only in turbo mode. I don't use turbo very often so I haven't bother taking it back to the dealer yet. I'll be curious to hear if your dealer determines what the cause is.
