I have, many riders have not. UCI added a rule to add tabs to front forks so wheels don't come out.
Try this. Turn bike upside down and remove rear skewer. Then from a stop, do a hard/fast acceleration in the big ring. Does the wheel tend to pull out - or into the dropout? I think you saw the clip I did. Our Venge, the wheel pops out. My hand, would put out a mall fraction of what a rider might.
So here is what I know:
-They have not contacted me back after I followed their system of both calling and contacting the dealer.
-The wheel comes out of the Venge when unclamped while is does not on other bike I tested - EVO, MASI, (Raleigh same as Venge turns out. But all solid Alloy dropouts).
-There are steel plates (I think hardened) on the dropouts that are harder than the hub axle material.
Here is what I assume:
-There was upper tier power and chain tension coaxing the wheel out of the dropouts.
-The clamping was not as tight as it could have been, but as tight as used on other bikes without issue and the hardened steel face did not provide enough bite/friction. So under shock on a sprint of a relatively powerful rider the wheel was pulled out.
If the dropout angle had been more vertical, and/or they had not had steel plates, that level of clamping force would have been fine.
