I've had my leather seat (driver's side) separate at the seam on the seat back, close to the lumbar, next to the door. It has left a small 1/2" hole on the seam. My car is an 04 but out of warranty because I drive a lot of highway miles (currently 58,000.) But it seems early for that to happen in the life of the car. Anyone else experience this? How is it fixed?
