Ever since I got my car new, I had complained about a seat issue. I have a problem where I have to rock the seat to lock it in position. Lately I also noticed the seat had been moving during stop and go traffic. The $%^&* at Nissan kept denying there is a problem. Matter of fact, I just went to a BBB arbitiration with them last week ( dont know the result yet). Before I couldnt really show them the problem just because you have to own the car to know the problem, but I got pissed off at hte car earlier. I grabbed the front of the seat, I noticed the whole thing rocks up and down when i jerk it by the paddings. The rocking stops when I put the seat either all the way up or all the way down through the adjustment.
