Here is another common problem with the G35 Coupe. The damn seat rails. Tons of owners realized that after a couple miles on the car, the seat will start rocking. A few idiots out there thinks that this is a "new" Luxury feature from Nissan. Claiming that their car is very Luxiury because they can rock back an forth with the seats.
However, the pictures below says otherwise. The reason why the seats are rocking is beacuse the rails are cracking and starting to fail. The cost of the repair is between $800 - $1200. A few owners decides to weld the rails themselves instead of replacing them. Cheap ass mother fuckers if you ask me. Intakes and body kits over safety I guess.
The cause seems to be a bolt coming loose making the seats rock back and forth. And if not caught early, the rails will start to warp and crack.
