Perforated leather seat in my 2003 350z popped open in hot weather. I was lucky enough to find the matching burnt orange leather on ebay and repaired locally. Additionally the regular leather on the seat is wearing extremely fast. It will have to be replaced as well. Burnt orange leather does not grow on trees around here. The mileage is low by many standards, but out of the 36k warranty window.
Problems with the front driver and passenger seats. The consumer observed abnormal seat wear on the front driver and passenger sides. A TSB was issued regarding this problem but the manufacturer has made to attempts at fixing the problem.
350z track model driver's seat moves side to side when turning. Makes a knocking noise and you feel the seat shift. Has been verified by hill Nissan, but they say that there is no fix available for it, and that replacing the seat with a similar one would leave me with the same problem. They said if a fix became available, they would inform me. I am worried that the seat is not structurally sound. Date given for occurrence is a guess at first notice of it. It occurs constantly.
