Air Bag Light On problems of the 2004 Nissan 350Z

I bought a 2004 z350 and I bought it on mother's day last month and I got the car in the abarat was already on the car the light was already on when I purchased a car from a dealership and I was told that it was against the law to sell a car with the airbag light on.

2004 Nissan 350z. Current mileage - 58,000+. Purchased new from a local dealer in November of 2004, after searching all of the dealers in central florida for the z that had the trim and safety package that we wanted. Beginning in 2007, the vehicle has had ongoing problems with the airbag light / airbags / diagnostic unit: 08/08/07 - airbag light is on - “false code� 08/14/08 - airbag light is on - “ordered left side airbag� 08/27/08 - “replaced failed left airbag unit� 11/11/08 - airbag light is on - “found pass codes clear all ok� 05/03/10 - airbag light is on - “needs diag unit and pass side curtain air bag� 06/22/10 - “replaced diag unit and rh side module� 11/08/10 - airbag light is on - “recommend lh front side air bag and diagnosis sensor� we were told by our dealer that the diagnosis sensor would be covered under warranty because it was less than five months since it had been replaced, but that we would need to pay over $700 for the airbag to be replaced. Logic tells us that the airbag may not need to be replaced if the diagnosis sensor is bad, but our local dealer is telling us that Nissan will not allow the diagnosis sensor to be replaced without also replacing the airbag. Logic also tells us that, unlike other parts, the airbags are not “wearing� items that require maintenance or replacement (unless they deploy, of course), so why do they need replacing? we contacted Nissanusa and asked that the faulty diagnosis sensor be replaced with one that will work for longer than five months, and will stop giving false codes. We also asked Nissan to replace the airbag at no cost to us because it is their 'requirement'. This morning, a regional representative from Nissanusa finally contacted us, and we were told that we would have to pay for the airbag if we wanted the faulty diagnosis sensor replaced! our concern is for our safety. What will happen if we have an accident? will any of the airbags deploy??.

Airbag light on 2004 350z touring roadster continues to flash. Diagnostic investigation gives no particular code that leads to prompt correction of airbag system malfunction.

On 06/08/09, I took my Nissan 350z in to for an oil change and because the air bag light was flashing. I received a call later that day indicating that the entire system would need to be replaced. The costs quoted for this service were: - diagnosis (already paid) $120. 00 - replacement of 2 parts $1,450. 00 - tax, repair not estimated the car has only 31,360 miles on it and has always been garaged and seldom driven in the winter. I have never had this type of problem with any other vehicle that I have owned. The car was purchased at this dealer on 04/28/04 and is 5 years and 2 weeks old. I spoke with the regional specialist on 6/15/09), and she informed me that Nissan was not willing to provide me any assistance in this matter. She said she had also covered this with the district manager.
