You would be better off taking care of this problem yourself. With my experience with this annoying problem it may be a hard sell to get them to fix it for you for free. You can use this discussion as a reference...I've also discovered the wet seat belt problem, but haven't mentioned that to them yet but I'm hoping they'll cover that too.
Run channel fix use Shin Etsu...
Personally I wouldn't buy the Honda Extended Warranty. Once you get the headlights, run chanel, and seatbelt problem fixed you probably won't ever use the warranty again. If you are willing to plunk down $1100 for the warranty figure out if it will be cheaper to fix those small problems yourself and save that money for a rainy day.
