I received one of the Cuisinart Prep 11 Plus food processor over the holidays. Within the first month the plastic motor drive cover cracked, this seems to be a semi-common problem. I have spent the last month emailing back and forth with Cuisinart/Conair trying to just determine what the deal is with it being under warranty (or how to repair it) or not. After a month of them sending replies asking me for just one more bit of information rather than asking me what they needed all up front they finally tell me what the deal is. I have to pack up the entire unit (including the parts) and ship to them along with $10. Then they will tell me if it is under warranty or not. They gave no indication how things might happen from there including if they decide it is not under warranty.
I started Googling a bit after finally getting their actual reply and apparently the plastic shaft is easily replaceable and about $15-$20 off Amazon.
Cuisinart's customer service seems to be in the same circle of hell as Frigidaire.
