On the 2005-2010 Nissan Pathfinder, nissan's radiator warranty extension applies to all 2005-2010 Pathfinder vehicles equipped with automatic transmissions. It states that an internal crack in the radiator oil-cooler tube may occur on a small percentage of vehicles, allowing internal engine-coolant leakage and potentially damaging the transmission. The document does not support a 60,000-100,000-mile failure band or universal occurrence.

Common Symptoms

  • coolant and automatic-transmission fluid inspected for cross-contamination
  • radiator oil-cooler integrity pressure-tested
  • transmission operation and VIN warranty history documented

How to Fix

If contamination or unexplained coolant loss is suspected, stop driving and have the coolant and automatic-transmission fluid inspected, pressure-test the radiator circuit and verify VIN-specific warranty history. Follow the service procedure for the proven damage; do not apply a universal cooler bypass. Do not buy a radiator, external cooler, transmission fluid or transmission from this page; contamination extent, cooling configuration and VIN fitment must be established first.

On the 2005-2012 Nissan Pathfinder, the R51 Pathfinder is prone to rust developing around the rear liftgate, particularly along the bottom edge and around the license plate area. Water gets trapped behind trim pieces and the spare tire well can also rust through. This is especially common in northern/salt belt states but occurs nationwide. The issue is caused by inadequate drainage and corrosion protection in the rear body panels.

Common Symptoms

  • Bubbling paint on rear hatch
  • Visible rust around license plate area
  • Rust holes in liftgate bottom edge
  • Water intrusion in cargo area
  • Spare tire well corrosion

How to Fix

Early stage: Sand affected areas, apply rust converter, prime and repaint ($200-500 DIY or $500-1,200 at body shop). Advanced rust: Panel replacement may be required ($1,500-3,000). Preventive measures include keeping drain holes clear, applying rust inhibitor spray annually, and checking behind rear trim panels for trapped moisture.

On the 2001-2012 Nissan Pathfinder, the cast iron exhaust manifolds on VQ35DE and VQ40DE equipped Pathfinders are prone to cracking due to thermal cycling. The passenger side manifold is most commonly affected. Cracks cause an exhaust leak that produces a ticking noise on cold starts that may diminish as the engine warms up. Over time the crack worsens and the leak becomes constant.

This issue also affects: Infiniti FX35, Infiniti G35, Nissan 350Z

Common Symptoms

  • Ticking or tapping noise on cold start
  • Exhaust smell in cabin
  • Rough idle
  • Decreased fuel economy
  • Check engine light (O2 sensor codes)

How to Fix

Replace the cracked exhaust manifold. OEM manifolds tend to crack again; many owners opt for aftermarket headers or upgraded manifolds. Replacing exhaust manifold gaskets at the same time is recommended. Cost: $400-900 at an independent shop.
