Front Air Bag Sensor Control problems of the 2002 Infiniti I35

I was traveling approx. 70 mph on the interstate and the vehicle "jerked", lost power and re-accelerated without losing power. The tcs off/slip and service engine soon lights all came on simultaneously. I stopped by the store and had difficulty starting the car. I immediately drove to advance auto parts to have it "diagnosed" because it was right across the street. It was diagnosed as a "cam shaft position sensor". Our mechanic recommended we contact Infiniti because there was a recall for this same issue (03v455000). I contacted taylor Infiniti in augusta, GA and was told by the service manager, chandra, that the recall campaign had ended. She also knew nothing about the airbag recall campaign (13v136000), and there was nothing more she could do to help me. Within a couple of days, the car began shutting off while in operation (while slowing down, stopped at red lights, in the middle of intersections, etc. ). I have not driven the vehicle in 3 weeks, as it is obviously not safe to drive. I have checked several online Infiniti owner forums, and there are literally thousands of people who are having this same problem. I wasn't aware that safety recalls had an "end" date. I called taylor Infiniti back and was told my VIN wasn't included in any of the campaigns. I feel strongly that the recall for this issue should be re-opened and include a wider range of VIN numbers, if not to include all '02 I35s. I am terribly frustrated because I don't feel as if I should have to pay hundreds of dollars for repairs that are obviously related to this issue. Coincidentally, we also replaced the lower control arm on my car in December of 2012 at an out-of-pocket cost of over $800, when this issue was also the subject of a recall campaign (02v146000), which they also said my VIN was not included in. I was told the car "is an '02, and these issues are sure to arise".
