I have always loved Costco - but I will not be buying appliances there any longer and advise you buy a warranty if you do. They don't stand behind there appliances like they have other things in the past. When I wrote Costco I got an oh well to bad response. When you buy something for just under $3000 you expect it to last. 2 years and 1 month and the unit died and I found out it is a known problem but Costco didn't worn buyers and wouldn't honor warranty that was just 1 month past. Why no recall , why no notice of known issues. Do they have to honor it? of course not - I just have come to expect more out of Costco
