Query: Keeps breaking

I bought one of these just over a year ago. The gear housing broke after a year and since then it has been in for repairs twice. Both times, it broke again the first time I used it. It cost over [...] to get fixed and takes a month since the part has to be ordered in. I would never buy a Kitchenaid again. Kitchenaid has not been helpful on the phone as the warranty is expired and they say I should just take it in again. They also told me that mixing bread dough is hard on the machine ... then perhaps they shouldn't promote its bread kneading capability so enthusiastically.
