2003 Nissan Xterra SUV XE 4WD 4dr SUV (3.3L 6cyl 5M)
Xterra
 Our Xterra new in '03 had major mech issues right away.  Dealer would not admit the engine knock until 20K when it got really severe.  Horrible experience dealing with dealer and Nissan USA to get new engine approved, they held the vehicle for weeks before starting work even though parts were at the local distro hub.   This turned me off from Nissan forever.   Also had bearing in rear diff fail at 8k miles, replaced under warranty no prob, but weird to have this many issues.  Since, the Xterra has been quite reliable to current 90k miles.  Several leaks (oil pan, valve cover) which are due to the eng replacement at 20ku, but nothing severe.  Looks and runs great now
