1997 Nissan Pathfinder Problems: 6 Known Issues

On the 1996-1999 Nissan Pathfinder 3.3L VG33E V6, nissan recall 11V-244 and campaign bulletin NTB11-064d cover certain 1996-2004 Pathfinder R50 vehicles registered in specified salt states. Salt-related corrosion can develop at the left front strut housing panel and may allow contact with the steering column and damage to steering or brake components. The recall covers 1996-2004 vehicles; this page lists the 1996-1999 model years within it, and the VIN and state of registration decide eligibility.

On the 1990-1999 Nissan Pathfinder, both the 3.0L VG30E (1990-1995) and 3.3L VG33E (1996-1999) are timing-belt engines. The belt, tensioner, and idler are service items that harden and wear with age; a failed tensioner bearing produces a ticking or scraping noise from the front of the engine, and a snapped belt leaves the engine cranking but not starting. These VG-series engines are widely documented as interference designs, so a broken belt commonly bends valves and can total the engine. A mid-1993 production change moved the VG30E from square-tooth to round-tooth belt/sprockets, so the correct part must be verified by inspection on 1993-1994 trucks.

On the 1990-1999 Nissan Pathfinder, the V6 Pathfinders of this era use a camshaft-driven Hitachi distributor that houses the optical crank/cam position sensor and rotor inside a single unit. It is one of the most frequently reported failure points on the WD21 (1990-1995 VG30E) and early R50 (1996-1999 VG33E) trucks. Internal wear, a degrading optical disc, a failing internal coil, or the rotor-retaining screw working loose leads to intermittent or complete loss of spark and timing signal. Failures are often heat-related, showing up once the engine is warm and worsening under load.

On the 1996-1999 Nissan Pathfinder 3.3L VG33E V6, the R50 Pathfinder's front lower ball joints are a common high-mileage wear item. As they wear, play develops that produces a clunk or rattle over bumps, steering wander/vibration, and uneven (inner/outer edge) front tire wear. A complete failure can allow the control arm to separate from the knuckle, so a badly worn joint should not be driven. Diagnosis is a standard rock-the-wheel top/bottom check on a hoist.

On the 1996-1999 Nissan Pathfinder 3.3L VG33E V6, on the VG33E (1996+), the fuel-rail pressure damper and the fuel pressure regulator use internal diaphragms that fail with age. A ruptured diaphragm lets raw fuel weep from the damper or get drawn through the regulator vacuum line into the intake, producing a strong fuel smell, hard/long cranking hot restarts, and misfire or rich running. A simple test: run the engine a few minutes, shut off, and pull the vacuum line off the regulator/damper; fuel in the line confirms a failed diaphragm.

On the 1990-1999 Nissan Pathfinder, the VG30E and VG33E exhaust manifolds warp slightly over years of heat cycling, which snaps the manifold-to-head studs (the rear stud on the passenger/right bank is the most common casualty). This creates an exhaust leak with a characteristic ticking/tapping that is loudest on a cold start and quiets as the engine warms and the manifold expands to close the gap. Nissan acknowledged the problem in a Technical Service Bulletin and released higher-strength replacement studs.
