If a replacement is offered and it is close to the expiration period, there needs to be a minimal amount such as 6 months, a year, etc. in case the replacement is a bad unit. Same deal on a repair, or at least the repaired component needs to have warranty coverage if IT is the issue a second time.
Manufacturers that offer a premium product should naturally have longer warranties. While technically they are not responsible for 1 day outside of warranty, a company that wants to maintain a good relationship with their customers, especially those companies where you pay a premium, they should do all they can do maintain that good relationship. Always that is covering a design fault even out of warranty IMHO if they care about their reputation. Sometimes that is a repair outside of warranty depending on the situation. They should also always try to do repairs at a reasonable price. I think that is probably my biggest issue with the way they have handled this case. Yes, it is out of warranty, but (a) they would have been wise given the situation to keep their customer happy, and (b) their repair estimate was insanely high.
I once had a Canon camera, and not a pricy one, that was probably 5 times out of warranty because it was so old. It developed an issue and I called them and they said that even though it was out of warranty, they still had parts available for it, and they chose to repair it at no charge. I was very impressed, and I spend my "camera" dollars accordingly...
