Has anybody had any issues with the quality or workmanship of the leather seats. My driver side zipper on the back portion of the seat split open. I took it to the dealer for their inspection, service manager took pic, got approval for replacement and waiting for replacement and a call to set up appointment. According to the service manager the back portion retail cost was around $1,300. Thinking that I am not the only one with this manufacturing defect. It's been over two weeks.
