I really don't think this kind of nonsense is unique or even concentrated with any particular brand. Personally, I've had very good experience with Honda dealers (sales and service). I'm sure there are ones that are lousy too. Subaru - one great dealer, one terrible. Same with Toyota.
Sadly, I'm not surprised at the lack of response from Honda. Unfortunately, that's the way of the corporate world. They typically give the "dealers are independent businesses" line. BUT - when it would ever come down to a dealer actually denying a warranty claim without justification and backing from corporate, I think (hope?) they'd be more help. More than likely - the dealer wouldn't even try it. They're slimy but they're not stupid and they know its a losing hand.
