Air Bag Not Deploy problems of the 2009 Cadillac SRX

I am writing regarding the Cadillac Srx VIN # [xxx] I purchased in 07/09 from massey Cadillac. We have a serious problem with this vehicle and the number of times it has been in the Cadillac repair shop since it was purchased. The most egregious defect is the passenger airbag. The vehicle has been in the repair shop a total of nine times for the same issue. The passenger airbag does not activate when a passenger is seated in the passenger seat. There is a safety concern & and a potential negligence claim for Cadillac because if a fatal accident were to occur and the airbag failed to deploy and the passenger was either injured or there was a fatality, Cadillac has been on notice for months that there was an issue with this vehicle. The vehicle goes into the shop, stays for a few days, is returned to me and the same issue happens again -- a passenger is seated in the passenger seat and the airbag sensor does not register that a person is seated there. Note: as of 4/29/13 the vehicle is sitting in the service department of massey Cadillac orlando waiting to be repaired. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
