If the car is still in the 3yr 36k warr hell yes make them replace it. One of the reasons that it it cracking is because it is a plastic vinyl material that it is made of. It is designed to look good for a long time and be weather proof but it can not with stand the constant entering and exiting the car because of the high bolster design of the race inspired seats.My driver seat has some cracking/tearing at the stitching. Has anyone else had this problem? I understand it's covered under factory warranty but should I push to replace? Any advice appreciated.
