Exhaust manifold studs broke on passenger's side of engine. Found it a common problem that nissan won't fix.
1995 Nissan Pathfinder engine complaints
Page 2 of 3: complaints 11 to 40 of 54, newest first, as owners wrote them.
Bolts on exhaust broke.
@ 50k left manifold failure - replace/covered by warranty. @ 65k right manifold failure, not covered by warranty, paid out of pocket to replace. Now, @ 90k another manifold failure.
Driver and passenger side exhaust manifolds have failed and have been replaced. Carbon monoxide was entering directly into the passenger compartment and forced me to pay the ~$900 to have them repaired. Attempting to receive reimbursement from manufacturer.
Passenger side front most cylinder had one exhaust manifold stud break off and after carefully inspecting other studs on passenger side at least one more is broken. Seems like a common problem, but very expensive to fix also very frustrating!!!
The left and right exhaust manifolds warped.*ak
At my 60k service the mechanic diagnosed a faulty exhaust manifold and replaced it. Fortunately, this was covered by my extended warranty. I've come to realize that is was a common problem with nissan pathfinders although no recalls have been instituted. I'm concerned that this will reoccur again as my vehicle approached 100k.
Exhaust manifold stud broken
Exhaust manifold bolts broken. Obviuosly nissan is aware that this is a constant problem for pathfinder owners. Their neglect at addressing this situation compounds my frustration. Wilson nissan in logan utah espects me to replace them at my cost every time they break, which could happen as soon as they are replaced. I suggest a class action lawsuit from all owners of these vehicles is in order to get nissan to address this problem. Had known of this I never would have bought a nissan product, and I never will again.
No summary. Dt
Exhaust manifold studs broke, causing exhaust leak on right & left sides of engine.
Exhaust leak at right exhaust manifold. Three studs failed allowing manifold to pull away from cylinder head causing head warpage. Fourth occurrence on same side of manifold.
Problem with exhaust manifold bolts that secure it to engine head. Nissan is aware of the design flaws. Manifold directs hot exhaust gas back into the exhaust system to be burned or expelled from the car. No recall, but nissan knows the angle of the manifold curve is misaligned. Gas hits the metal head on and overheats the manifold and studs. The heat warps the metal and shears the bolts which should keep the part secure.
Right side manifold failed, bolts broken in engine. This is a known nissan defect and subject of many complaints.
I was told by a mechanic that this an extremely common problem due to poor manufacturing and this problem is under investigation. Didi they ever do a recall? I was also told that if I fixed the manifold and head bolts that this problem would repeat itself. Is there any thing I can do ? Thank you.
Vehicle has stalled 5 times around 35-45 MPH, dealer has replaced battery and alternator. This has not remedied the problem.
While driving heard noise from the exhaust system, and exhaust fumes were coming into vehicle. Vehicle taken to dealer, and informed consumer that bolts on exhaust manifold had broken off. Warranty expired, and there was no recall. Feel free to provide any further information.
A connecting rod failed and destroyed the engine at normal operating speed. Was told that certain 6 cylinder nissan engines of 1995-96 were recalled,warrantied for just such a problem, failed rods, crankshafts.
Exhaust manifold bolt broken, also happened 5/00 with right manifold.
Three bolts from engine manifold broke while driving at highway speed of 55 MPH. Dealer/manufacturer were not notified at this time. *ak a mechanice at a garage stated the bolts are made of aluminum and that they break very easily.
Manifold warps breaking bolts & leaks exhaust. This time instead of the bolts breaking they are pulled out of the cylinder head requiring the head to be replaced.
Manifold gasket leaking (I also owned a '91 pathfinder that had to have each manifold gasket replaced twice) . Several transmission parts req'd replacement as well as the computer that drives the transmission.
Right oem manifold #4, installed by nissan is warped and leaking exhaust again. This is now the 6th one to be replaced counting both right and left. All replaced using oem equipment, purchased and installed by authorized nissan dealer
There exists a condition where the exhaust manifold warps, shearing the bolts. This is a $500+ repair job. This has been known to nissan since (at least) 1992. Yet they continued to manufacture a flawed design. Is this not fraud? The federal safety agency states on the website that safety-related failures must be repaired by the mfg- in this case, if the vehicle is at idle exhaust fumes enter the cabin, and can suffocate those inside.
Exhaust manifold bolts are failing, causing exhaust leaks. This is a well known and documented problem (tsb94041) that any mechanic will attest to. Total repair is 800.00 for both sides. Nissan refuses to offer any help in the matter. Carbon monoxide may enter the vehicle if it is not fixed.
Exhaust leak on right side due to cracked bolts and warped manifold. There is a posted recall for the 1996- 1998 pathfinder that have this same problem, why would this not cover earlier years if this is a known manufacturer defect.
Right exhaust manifold replaced, then 40000 or so miles later bolts broken on both the right and left manifold. Reverse in the transmission did not work, had to replace the complete transmission. Drivers sunvisor is bad design, you have problems seeing when it is down.
This problem involves the exhaust manifold and the bolts that secure it to the engine head. Thousands of mechanics around the world will testify that nissan is well aware of the design flaw inherent in the manifold. Heres what happenssuper heated exhaust fires out from the piston head and is captured by the manifold. But, due to the angle of the manifold curve (the bend in the metal piping) the gas hits the metal too head on and over-heats the manifold. The heat is so intense that it warp the metal. The toque of the bending metal is so strong it literally shears the bolts that are supposed to secure the manifold to the head. The metal should never get that hot, yet it does solely because of nissans design flaw. According to the nissan dealer I talked with.this problem then leaks carbon monoxide into the car. One mechanic said he sees maybe 4 of these every two weeks! (pathfinder and maximas) this problem is costing consumers a lot of money. Please help.
Exhaust manifolds have both been replaced due to them warping and the leaking exhaust. They were replaced at 75,000 and 90,191 miles. Now at 143500 the right one is warped and leaking exhaust again. From what I have learned, this had been an ongoing problem with nissan and this engine in the trucks and pathfinders. None of the work done to repair these problems has been covered by any warranty.
Engine knocking when started cold. Transmission will not go into reverse. **** dimsii ivoq entry posted after 12/12/02 cut-over to artemis****724554. *ak
