I can't really tell what I'm looking at but if it's the pleather insert on your door starting to separate from the door panel, I found a guy that sells piping and you just mash it in and so far it's kept mine from getting worse.

The local upholstery shop I was referred to BUTCHERED the passenger side. I refused to pay, she got stuffy and said "well it's mine now then", I laughed and walked off. At least I didn't have to figure out how to fit it in the trashcan. It was beyond ruined.Caused by humidity and lack luster adhesion from the factory.
Looking at finding an upholstery shop local to replace mine soon with suede.
