I own a 2004 Nissan Armada. About 2 weeks ago while driving the red airbag warning light turned on and would not turn off. I just had it serviced today and was told that the front crash zone airbag sensor being that it is located outside of the front radiator grill ends up rusting out from the elements of our weather. Therefore it needed to be replaced. The car is out of warranty so therefore it was billable. After doing some research I came across a Nissan recall from January 2009. The NHTSA campaign id # is 08v690000. This recall was for the exact same problem with the crash zone sensor rusting out from snow/salt in the northern us states but was only limited to 2005-2009 pathfinders, frontiers and xterra vehicles. I feel that my vehicle should be included in this recall due to the fact that it is the exact same problem listed in the recall and I live in NY state which obviously has winters with snow and salt. The recall issued a redesigned sensor to correct the problem at no cost to the vehicle owner.
