You should be able to get a replacement pretty quickly by contacting NI on Monday. In the meantime I'd like some more details on this issue. You mentioned the cRIO died while driving... some questions:

1) Was this actually while driving (no human contact with the robot at all), or were you downloading code or otherwise working on the robot?
2) Did anything else happen at the time of the failure (massive collision, another component failed, etc.)?
3) Have you always used the PD module to power the cRIO?
4) Have you ever "hot connected" the cRIO by plugging in a live power cable?

Thanks!
