That was back in June this year, and I'd bought it as part of a D300 kit in March 2009.
The really annoying part was that it had hardly been used - I'd bought another couple of lenses quite quickly after the kit and the 18-200 got relegated for "when I can only take one lens" (which has turned out to be "never" so far). I only discovered it was broken when my girlfriend bought a second-hand D300 with no lenses, and I gave her the 18-200 as a starter. She uses it all the time now though, so it wasn't money wasted. Moral of the story: test everything a couple of weeks before its warranty runs out.
SkintBrit - Nikon told me the kit lens wasn't covered when I called to register for the 2 years, and again every time I called regarding that lens repair. It seems to me there's no way to get more than a year's warranty on a lens in the UK, except maybe paying for it. If you've got something that definitely, unambiguously says otherwise, I'd love to see it.
