Same issue, different items ( see previous complaints about the Xterra manual clutch). Car wouldn't shift into ANY gear. Towed to dealer. After a couple days, he said it was the clutch master cylinder and slave, not under warranty ( of course). Coincidental that the components failed two weeks after the dealer replaced the clutch and flywheel ?? I towed it home, and am now working on replacing it. What a hassle. Again, Nissan refuses to acknowledge their design deficiencies and do the right thing. Don't buy a Xterra with a manual transmission.
