Air Bag Light On problems of the 2008 Honda Odyssey

When passengers are in the passenger seat, the airbag indicator light states airbag is off. I have informed the dealership where I purchased the auto about this several times. Nothing has been checked. I'm very concerned about this, my husband and I travel a lot now and a crash and a non working airbag could be the difference between life and or serious injury.

New 2008 Honda Odyssey with less than 200 miles, when the problem first occurred 1. Vibration in the steering wheel while braking. Happened every time when stopping at stop light or when slowing down. The Honda service dept. Identified it to be a warped motor and they had to resurface it. They mentioned that this problem has been noticed in some other vehicles too, but they didn't know what caused the problem. 2. Passenger air bag light comes up while driving even when there is no passenger in the seat. The Honda service dept. Has looked at it twice now, as recent as 2/13/2009 and have mentioned that they don't know why it happens. . . That it also happens in one of the service tech's Odyssey van. Their solution to address this problem was to place a heavy object on the passenger seat! on both issues, I had opened a case with Honda customer service case #: n012009-01-0701207. The first time, the cust service representative tried to shrug off the vibration issue as not an issue. On the second incident, the representative sounded concerned and mentioned that he would also be upset about these multiple issues on a new van. He assured that within 2 days, a Honda representative will contact me to follow-up on this issue. But, never did I receive any call back. Due to poor response from Honda customer service, I haven't called them back as I don't get any proper response from them. I feel that I have been sold a "lemon" and that the Honda company should take this vehicle back and provide a new/different Odyssey van.
