There is a recurring problem with the exhaust manifold and the manifold studs breaking, resulting in an exhaust leak inside the engine compartment which causes exhaust fumes to enter the passenger compartment.

Exhuast manifold studs keep breaking causing leakage, fumes, and noise. Has happened 3 times in 45k miles at $500 to $1200 per incident. Have filed complaint with nissan consumer affairs (incident 4259794). Nissan declined to assist because they said vechicle was beyond useful service life. Even if that were true, the repairs I'm paying them for over and over should have a useful service life. I've been told by several dealers that this will continue to happen. Common nissan, fix this problem once and for all. I just want to have it fixed once and for all without having to keep on paying for this. Check out this forum http://forums.vmag.com/suvpathfinder0200 where there are literally 100's of complaints.

Exhaust manifold studs are broken on both sides. Dealership wants $1400.00 to repair. This is a common problem that nissan has been aware of and does nothing to compensate their customers for. Causes exhast leaks into the car.

Ref. Service bulletin #: fc0009202 / the federal safety agency item #: sb035797 -- exhaust noise and exhaust smell inside vehicle due to broken manifold studs. As the original owner of this vehicle, the right manifold studs broke at 36,705 miles and was repaired under warranty by nissan. At 48,654 miles, the left manifold studs broke and was repaired at my cost (approx $350). Now, at 113,500 miles, the left manifold studs appear to be broken and require repair. Nissan refuses to take responsibility, even though they acknowledge that this is a design flaw in their 1993 engines. For 1995 & 1996 models, they've extended their warranty to 100,000 miles. Then, in 1997, they introduced a new design which changed the bolt size from 8mm to 10mm bolts (rectifying the known problem). Even with such an acknowledgement, nissan refuses to warrantee the repairs! I strongly recommend that a recall be issued requiring nissan to upgrade the engine/exhaust systems in the pre-1997 nissan pathfinders (in that, this broken manifold studs problem will continue to reoccur every 50,000 miles or so). Thank you. Sincerely, michael j. *akgall.
