My 2008 Infiniti G35 airbag and passenger airbag lights illuminated. I reset the lights and checked the wiring under the passenger seat but the lights came on again. I took the car to the dealer and they came up with code b1018, occupant sensor (unit fail) past code. They reset the lights and recommend changing the passenger seat bottom if the lights returned. The cost?....$6137 but they will give me a discount, charging me $4176. This model was recalled for this problem but not my car...according to the VIN. My car was manufactured sep 2007, right in the middle of the recalled vehicles manufactured interval. I believe Infiniti should be required to assume the cost of this expensive repair by including it in the recall.
