2005 Nissan Pathfinder SUV SE 4WD 4dr SUV (4.0L 6cyl 5A)
Problems solved, hopefully
 Purchased in July, 2010 with 82k miles on it from dealership without knowing what issues the vehicle had. After reading all the reviews I took preemptive measures and replaced the radiator myself, $200. Evap code tripped on the way home from dealership same day of purchase. Took evap canister out, found out a tab holding the evap valve in place was insufficient and zip tied the crud out of it and haven't had a problems with it. According to carfax report the fuel sender had already been replaced. Haven't had an issue with it since, but transmission has always made a small clacking noise when it makes its first shift after start-up, hope this is normal.
