Sudden, no symptongs before- clutch stuck engaged?

Agreed, now would be the ideal time to have the hydraulic system checked out and/or serviced. Your clutch needs to be 100% reliable, and the fact that it failed on you once is one time too many.

I'll never forget the time I had to replace a broken clutch cable on the side of a highway onramp in the middle of November. That experience could have been avoided had I performed proper maintenance and service while the car was safely sitting in my driveway.
