I have a 2010 GT that I bought about a few months ago from a nissan dealer. Right away, I noticed something strange with the driver's seat. Seems the portion of the seat back that faces the door has some framing components that are basically "exposed" behind the leather (i.e., no padding). Recently, I also noticed the stitching is starting to come apart at the top of the seat back. I'm thinking the air bag unit may have been removed, which would be a big red flag. Is this how the seat in this area feels or is something missing under the leather?
