All 1 Known Issues
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.
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.
