Air Bag Not Deploy problems of the 2011 Nissan Juke

The passenger airbag disabled light comes on occasionally even when my daughter is seated in the passenger seat. She is approximately 100 pounds. It seems that the light is on more than it is off, which is concerning because in event of an accident, it would mean that the passenger airbag does not deploy.

Slowed down to turn and was rear ended by another vehicle, causing damage to back of my car, however the air bags did not deploy at anytime during or after the accident. Multiple complaints during the time I've owned the car: hesitation when going from lower speed to higher speed not accelerating to higher speed, my complaint of engine noise documented in the dealer service invoice on Dec. 1, 2011; 3 rough, jerky , uneven ride, oil leaks. Fuel pressure sensor re- torqued and gaskets replaced in may 2012 and notation made in comment section: ' performed system check as stated in bulletin', but I never received any notification from Nissan about an official re-call on parts. Check engine light complaint to dealer service dept. On sept. 27, 2012 and notation made in notes ' p0303 stored in ecu' and check engine light complaint oct. 31,2012 and stated cause by service dept. Is 'cylinder lost compression' and charged me $ 8080. 12 for engine work : gaskets replaced on the adapter, exhaust, manifold and water pump. Nov. 2, 2012 the dealer service dept. Found 60% oil inside tubes and same failure code appeared p0303. Spark plugs replaced Dec. 21 2013, and on Jan. 10, 2014 the coils were replaced , the spark plugs were replaced again ,and the service dept. Noted a loss of power in test drive and again noted water in the fuel. I've had multiple numerous complaints , the above noted is documented in the service dept. Paperwork. I was not aware of the re-calls by Nissan until 1 month ago. To date , Nissan has not contacted me.
