So why do bike manufacturers offer 1, 2 3+ warranties?
1. For weak welds which might take time to manifest themselves
2. Because its sounds good in their marketing literature
But if you tried to claim a bent chain stay under warrenty, I bet they too would tell you where to go.
You buy a supercar (SW seems to like Aston Martins), drive it for a year look after it but one day you notice a dent in a side panel. When you take it to the dealer do you expect that it will be repaired free of charge? Course not, so why should bike manufacturers be any different?
