Why, in the case of Renault, only one failed, twice?
Well those are two different failures. In the case of Torro Rosso the upright structurally collapsed, as in the hubs were separated from the uprights to create the problem.
In this example, it looks to me (just based on studying the in car replays frame by frame and it's subsequent damage) like something loosened up and machined into the inner part of the wheels. Petrov's incident started with sudden loss of pressure in the tire and the inner part of the wheel being detached from most of the rim. Quick Nick was fortunate really that his ass'y just locked up. So based on what I've seen it looks like a bolt, etc backed out or stripped out of the upright an interfered with the wheel. So in effect an upright failure but not a collapse.
