1990 Nissan Pathfinder Engine

INQUIRY WHETHER NISSAN IS OBLIGATED TO REPAIR OR COVER THE COST OF REPAIR FOR BROKE EXHAUST MANIFOLD STUDS WHICH COULD CAUSE CARBON MONOXIDE PROBLEMS. *PH *LA

MULTIPLE STUDS BROKEN ON EXHAUST MANIFOLD MULTIPLE TIMES. RIGHT (PASSENGER) SIDE TWICE. LEFT SIDE ONCE.

NISSAN RECOGNIZED EXHAUST MANIFOLD DESIGN DEFECTS LEADING TO MANIFOLD WARPAGE AND REPEATED EXHAUST MANIFOLD BOLT BREAKAGE. EVENTUALLY CAUSING EXHAUST GAS LEAKS AND NOISE PROBLEMS . NISSAN RECOGNIZES DESIGN FAILURE BUT REFUSES TO FIX THE PROBLEM. I'VE SPENT OVER $1500 REPAIRING EXHAUST MANIFOLDS AND BROKEN EXHAUST MANIFOLD BOLTS. PLEASE HAVE NISSAN RECALL THE FAULTY EXHAUST MANIFOLDS AND BOLTS!

NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK

EXHAUST MANIFOLD WARPED, CAUSING BOLTS , THAT HOLD THE ENGINE, TO BREAK. VEHICLE MADE A LOUD NOISE. ALSO, EXHAUST VAPOR GOT INSIDE OF VEHICLE. DEALER SAID IT WAS A COMMON PROBLEM, AND THAT THE BOLTS WERE TOO SMALL TO HOLD THE ENGINE. *AK

EXHAUST MANIFOLD LEAKS ARE A COMMON PROBLEM WITH THE PATHFINDER WITH MANY OF THE REPAIRS BEING PERFORMED MULTIPLE TIMES OVER THE LIFE OF THE VEHICLE. MY FIRST REPAIR WAS COMPLETED IN THE FALL OF 1996 WITH THE MANIFOLDS REMOVED, TRUED TO FACTORY SPECIFICATIONS, BROKEN MANIFOLD STUDS REPLACED WITH THE FACTORY RECOMMENDED PARTS AND REASSEMBLED BY A LOCAL REPAIR SHOP. THE REPAIR CAST $800.00 AND LASTED 6 MONTHS. NISSAN IS AWARE OF THE PROBLEMS WITH THESE MANIFOLDS AND IN 1997 ISSUED A "SILENT" RECALL ON THEIR 1996 AND 1997 PATHFINDERS BUT WILL NOT HELP THE FOLKS WITH THE OLDER TRUCKS. FACTORY REPLACEMENTS OF THE MANIFOLDS HAVE NOT ELIMINATED THE PROBLEM FOR OTHERS AND AT $800.00 FOR THE REPAIR DOING IT MORE THAN ONCE SEEMS EXCESSIVE. THERE ARE SEVERAL WEB SITES THAT HAVE ADDRESSED THIS PROBLEM AND IT SEEMS WELL DOCUMENTED, WE FEEL THAT NISSAN NEEDS TO BE PUSHED TO DO WHAT'S RIGHT. THANK YOU. *AK
