Like Hillstones is saying, you should treat it as more of a safety issue than a warranty issue. First things first, you're going to have to take your car to Honda and get your airbag codes scanned. When the scan results come back, if they are related to a warranty, you won't be charged for the labor for the scan, otherwise be prepared to fork out no more than $100 for getting your codes checked. If the codes are related to the seatbelt buckle, the dealership might try to argue that the airbag system is electrical and not covered in the seat belt warranty. They might try to convince you that the warranty only covers mechanical failure of the buckle and belt itself. If they do that, call BS and call American Honda at (800) 999-1009 to make a claim. You should get that buckle fixed for free. As far as the passenger OPDS sensor goes, there's an extended warranty for that. It's 10 years or 150,000 miles--whichever comes first. Either way, as long as your SRS light on your dashboard is lit, you're pretty much screwed when it comes to an accident because all 6 airbags and (I think) the explosives in your seat belt retractor are disabled. I wouldn't put this issue off til next week. Get it fixed asap.
I took my car to Honda and they scanned the codes. The codes came back as seat belt buckle and passenger OPDS. I filled out some paperwork and they got the replacement parts ordered and in by the next day. I took my car back to Honda the next day and waited about 2 hours in the waiting room for the mechanics to replace the defective parts. I haven't had any SRS problems since then.
