Hello my fellow G37 owners!
I've been a long time lurker of this site ever since I bought my 2010 coupe in November. I bought it used so of course it has wear and tear on the interior, but starting friday I noticed parts of the drivers seat are beginning to turn yellow. I have the wheat interior. I keep a VERY close eye on my car so the yellow staining is new. I've tried wiping it down, but it doesn't appear to be coming off. I only leave my car in the sun at the most 4 hours a day(while I'm in class). Any ideas on what it could be or if it's possible to get rid of it? Has anyone else experienced this? I've tried looking it up in the search bar, but haven't found anyone else complaining about it yet. I've attached some pictures. It's hard to see in the pictures, but it's more yellow in person.
I'm taking in the car tomorrow morning to my local Infiniti to get some warranty stuff done to it. I know it's probably a long shot, but is this something you think they would fix? Or am I stuck with it until I buy a new drivers seat?
Thank you so much in advance!

Sorry for the giant pics!
