My wife just purchased a 2007 Pathfinder LE from Carlock Nissan in Jackson Tennessee. Needing to find out why the doors did not lock when putting vehicle into drive, the first question from the service rep was: Did you purchase the vehicle here? That was not the correct answer I was looking for. Answer to initial question is that no Nissan products offer auto lock and unlock. That is an unsafe condition for my wife and it needs to be corrected. It only takes a computer change in the vehicle. So far no resolution from Nissan Hot line.
