I have a '14 GT Premium, saddle leather, with 2,300 miles on it. When I picked up the car my wife noticed a small wrinkle, about 1" long, at the top of the passenger seatback. Rather than go through an ordeal at the dealership, I found a local auto/marine upholstery shop. The person with whom I spoke said he could take out the wrinkle with heat, which he subsequently did. He charged me $20 and I couldn't be happier with the repair. Maybe you can find such a shop near you.
