We were cleared for takeoff. Around 80 KTS we received a 'HYD 3 Low Press' caution message. It was the Captain's leg; and he aborted the takeoff. We notified ATC; exited the runway and ran the QRH for rejected takeoff. The message extinguished as we exited the runway. We talked to Maintenance and Dispatch; and since this was not a recurring problem in this specific airplane; we elected to try one more time. We also specifically briefed that if we got the same message again; we will abort again if speed permits. We received a second takeoff clearance and--this time around 60 KTS-- the same message appeared. This time we lost nose wheel steering on the runway as well. The Captain maintained centerline again. We came to a stop; re-engaged the nose wheel steering and went back to the ramp. Upon returning and speaking with Maintenance they determined that for some reason hydraulic system 3 lost pressure every time we moved the flight controls.The Captain aborted the first takeoff; because we hadn't yet reached the high speed phase of the takeoff roll. We talked about what happened; and decided that if we got the same message for our second attempt; if speed permits we would abort again; since hydraulic system three powers a good amount of flight controls and other important systems. We didn't put the aircraft in any undesired state. Only threat was that we lost the nose wheel steering during the second abort; but the Captain managed to keep the aircraft on the centerline.
A CRJ-200 flight crew rejected their takeoff at about 80 KTS when they received a 'HYD 3 Low Pressure' CAS warning. The warning went out after exiting the runway. They elected to takeoff again; received the same warning; lost nosewheel steering and rejected the takeoff again. They re-engaged nosewheel steering and taxied to the gate for maintenance.
