My Cherokee is 14 days old and the remote button for the fuel door got stuck when I went to fuel up this morning. Since I've only put two tanks of gas in it (I took a trip!
). I wouldn't consider it wear. The dealer put the part on order and says that they can fix it Tuesday when the part comes in (it's Friday).
They secured my door shut and recommened not trying to open it myself or it could be damaged.
I'm glad I have a full tank of gas and wasn't planning on going anywhere other then the store.
