There was a fault in the PD board (orange light) so once we cleared it it seems to work as expected.

A sticky fault on the PD is there to catch your attention to something that happened some time ago. I do not believe it affects the current usage or roboRIO brownout prevention. I suspect that other things changed as well, such as changing out the battery, and perhaps even some wiring or mechanical changes.
So the problem wasn't fixed by clearing the sticky fault. You may have a weak battery in your midst that will reintroduce the problem another day. You may also have some binding or electrical connection issues that are inconsistent and may reintroduce the issue.
So, please experiment and look for the issue. Also, be sure to open the DS log file viewer. You can click on the gear on the DS and open the viewer. Look at those logs and compare to others. If you don't see the issue, please post the file or a picture of the viewer.
The other day, the robot was pulling a bit while the drivers were testing it out. The programmers opened up the log viewer and clicked to see the motor currents while others started feeling motors and tracing wires. Sure enough, one drive motor was disconnected. Guess which team found the issue first?
My point is that the log file has valuable info and can help identify many issues.
