That's really too bad - my own experience was with a dyson DC21 canister that I bought in 2008 - after 6 years the power head started intermittently turning off while cleaning. They sent an entirely new power head no questions asked. It kept working for another 6 years without any other issues, then it just refused to turn on one day. I called and asked if they could service it and they said sadly the unit was discontinued several years ago but that they could send me the factory service manual and that the issue was likely with the connection between the reeling cord assembly and the main board. Sure enough, I guess reefing on that cord for 12 years caused it to come loose - 30 minutes later it was back up and running and I still use it to this day. Worth noting that this thing still cleans as strong today as it did back then. Perhaps Dyson Canada is different than US - I've seen a LOT of refurbished dysons on various marketplaces so I'm guessing they are not flawless - the fact there are so many refurbs however leads me to believe they are exchanging them without asking questions and that they are quite serviceable.
