general problems of the 2003 Nissan Maxima

This is reference to two situation concerning Nissan recalls. In 2014 I took my car to sansone Nissan dealer on rt 1, NJ to take care of the airbag recall issue NHTSA ref#15v287000. My airbag light was not on when I took it to the dealer, after I came home a week later the airbag light came on. I don't think the dealer took care of the recall issue, if they did my airbag light would not be on. I would like Nissan to give authorization to the dealer to correct this problem. My second issue was on Jan 2016, I was driving to work, all of a sudden the car shut off on me, the brake lock up and all I could do was stair to the side of the road. . I was lucky that there wasn't any oncoming traffic. I had to call the tow truck to have my car towed but before the tow truck came I tried starting the car again and it started. I was a few minutes from home, so I drove back home and I had my local mechanic picked it up and did a diagnosis on it. He said it was the crank position sensor, I purchased it and he installed it. The car started working a little better but my service engine soon warning light is still on. I did a little investigation and found out that there was a recall for engine and engine cooling recall #03v455000. I read it and found that the consequence on the recall is the exact same thing that happen to me. Again sansone dealer on rt. 1 in NJ is claiming that they took care of this issue but I was never told that this was a recall by Nissan. I wanted Nissan to correct this problem based on the fix under NHTSA ref# 03v455000. I've been taking car of all the maintenance on my car since I purchased it from Nissan but I feel that Nissan is responsible for these two issue, since it was defect in design on their end.

When was driving on 11/30/2015 and parking the car to go in a building and came back out and turn my light on and the trail light don't come on and the dash light don't come back on,and the power steering pump keep leaking.
