Bought a 13 cup food processor. After 3 to 4 months of using it, among other things, to shred Gouda cheese, the power transmission coupling in the main bowl failed. No more power could be transmitted to use any of the accessories. Household use. Only manufacturer recommended usage. Now I'm struggling with Cuisinart to make warranty valid, since I've had the appliance for 2.5 years before failure. 
It has great accessories. Just wish that quality could match them.
