When we bought our house last year we gutted the kitchen and got a KA fridge, KA dishwasher, and KA double oven with a Dacor range. In the past year we've had a few issues with the oven (related to the control board) and one of the guides on the top rack of the dishwasher broke. No problems with the fridge or range.
I did a lot of research on the appliances, and apparently every manufacturer within our price range (~$10K for the appliances) has some quality problems so my advice would be to buy an extended warranty, and shop based on price and features.
