ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

AT ANY SPEED VEHICLE WAS VERY LOUD, AND THE EXHAUST SOUNDED AS IF T MARBLES WERE RATTLING AROUND. A RECALL WAS ISSUED FOR VEHICLES OF SAME MAKE/MODEL AND CERTAIN YEARS, BUT THE CONSUMER'S VEHICLE WAS NOT INCLUDED. THE BOLTS TO THE EXHAUST MANIFOLD OVERHEATED AND BROKE OFF INTO THE MANIFOLD COVER. MANUFACTURER AND THE DEALER WERE AWARE OF THE PROBLEM.

THIS IS THE 13TH MANIFOLD STUD THAT WOULD NEED TO BE REPLACED. WHEN TAKEN TO THE DEALER THEY WANT TO REPLACE ALL 6 AGAIN AT A COST OF $636.00. I HAVE ALREADY HAD THE VEHICLE IN THE SHOP OVER THE PAST 2 YEARS TWICE FOR THE SAME ISSUE. THIS IS ALSO AN EMISSIONS ISSUE AS THE EXHAUST MANIFOLD SEPAREATES FROM THE ENGINE. I HAVE ASLO LOGGED A COMPLAINT WITH THE EPA. THIS IS A CHRONIC PROBLEM ON THESE VEHICLES AS WELL AS SEVERAL OTHER MODEL YEARS.

NHTSA complaint #756089 — an unverified report by a vehicle owner.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

IN DEC OF 1999 AN EXHAUST LEAK STARTED. COSTS $650 TO REPAIR SINCE MANIFOLDS WARP AND BREAK BOLTS OFF IN ENGINE BLOCK. THE BOLTS THEN HAVE TO BE BORED OUT AND THE HOLES IN THE ENGINE HAVE TO BE RETAPPED FOR THREADS. HE SAID IT WAS SURPRIZING THAT BOTH SIDES WEREN'T BAD BECAUSE PATHFINDERS WHERE "KNOWN" FOR THIS FAILURE AND HE SAID THAT EVEN THOUGH IT LOOKED LOOK AT THAT TIME, I SHOULD EXPECT IT TO FAIL ANYWAY SOMEDAY BECAUSE THEY ALL DO. ABOUT 1-YEAR LATER, THAT OTHER MANIFOLD DID FAIL IN THE EXACT SAME WAY AND IT COST ME $600+ AT ANOTHER SHOP TO GET THAT ONE REPLACED AND RETAPPED AFTER DRILLING OUT BROKEN BOLTS. THE MECHANIC AT THAT SHOP SAID THAT HE WAS SURPRISED BOTH SIDES WEREN'T BAD SINCE ALL PATHFINDERS HAVE THIS SAME PROBLEM AND I EXPLAINED THAT IT HAD ALREADY BEEN REPLACED. WHY ISN'T NISSAN BEING HELD RESPONSIBLE FOR THIS???

NHTSA complaint #716091 — an unverified report by a vehicle owner.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

CRACKED EXHAUST MANIFOLD AND BROKEN MANIFOLD STUDS CAUSED NOISE AND OCCASIONAL EXHAUST SMELL IN PASSENGER COMPARTMENT (WHEN ON FRESH AIR VENT). BROKEN MANIFOLD STUDS ARE A KNOWN DEFECT WITH A TSB IN EFFECT (OVER 10% OF ALL COMPLAINTS REGISTERED IN THE CUSTOMER COMPLAINT DATABASE RELATE TO THIS ISSUE). ONLY BECAUSE I HAD PURCHASED A NISSAN EXTENDED WARRANTY FOUR YEARS AGO WAS MOST OF THE REPAIR COST COVERED, HOWEVER, I WAS STILL REQUIRED TO PAY THE DEDUCTABLE. I DON'T FEEL ANY OUT-OF-POCKET EXPENSE SHOULD BE INCURRED FOR AN OBVIOUSLY PREVALANT DEFECT OR ENGINEERING DESIGN FLAW.
