Air Bag Light On problems of the 2004 Infiniti QX56

Passenger air bag light and dash light is on all the time.

We currently own a 2004 Infiniti Qx56. We have received error code b1177 which is for the pretensioner in seatbelts. Additionally, the airbag light is flashing. We understand from the dealership that the airbag light came on due to the battery being replaced and that it needed to be reset. The airbag light came bag on shortly thereafter and we took the vehicle to a private mechanic who scanned the code. He advised us of the error code and what it was associated with. Upon further investigation, it appears that an extensive amount of owners of the Infiniti Qx56 as well as the Nissan armada (sister vehicle) have this exact issue. We are unsure as to whether the airbags will fail if involved in an accident or if the safety belts will also not work. The vehicle has a 10 year seatbelt warranty but the dealers are stating that this item is not covered under warranty. This is obvious neglect and defect on the manufacturer's part and puts the owners of these vehicles at serious risk. We are a family of 5 with 3 small children. We cannot afford to purchase a new vehicle or to pay thousands of dollars to correct this safety related issue. Please advise.

Problems with passenger side air bag. Since the vehicle was new the passenger air bag deactivation indicator light has illuminated on the dash intermittently. The rear lift gate sensor would beep while driving. The dealer was able to duplicate the problem but could not offer an immediate solution. The driver's side washer sprayer did not function. The liquid being sprayed out of the sprayer was alcohol which discolored the paint on the hood cowling. The dvd entertainment unit broke. While driving over bumps the vehicle would lose cabin pressure and emitted a low frequency booming sound. The consumer was advised that a technical service bulletin was issued for that problem. The dealer did not have the parts available to fix the problem. The vehicles engine made a pinging noise while the consumer was driving . The vehicle was taken to the dealer who indicated that they were waiting for an answer from the tech line.
