Nissan is recalling more than two-million of it vehicles because of a faulty ignition relay that could lead to engine problems.  The Japanese automaker says the problems with the ignition relay may cause the engine to stall while running.  The recalled vehicles include the Nissan Cube, March, and about a dozen other models made between August 2003 and July 2006.  A spokesman for Nissan says no accidents have been reported because of the problem.  The automotive giant estimates it will only take 25 minutes for the fix at no cost to consumers.
