1995 Nissan Pathfinder

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.

A CATASTOPHIC FAILURE WAS EXPERIENCED IN THE RIGHT REAR TIRE - THE TIRE HAD SEPERATED AND GONE FLAT AT NORMAL HIGHWAY SPEED, THE VEHICLE WAS TAKEN TO A GARAGE AND THE TIRE WAS REPLACED WITH A NEW MATCHING TIRE (FIRESTONE WILDERNESS) CONSIDERING THAT ONE TIRE HAS ALREADY FAILED I WISH TO GET THE TIRES REPLACED IMMEDIATELY - WHAT SHOULD I DO?( DOT NUMBER: TIRE SIZE: P23575R15 )

I HAD TWO OF THESE TIRED COME APART ON ME. ONE FORTUNATELY WAS FLAT IN THE DRIVEWAY LEAKING AIR THROUGH THE MISSING TREAD AREA. THE SECOND WE WERE NOT SO FORTUNATE ON. WE WERE ON THE HIGHWAY WHEN TREAD TARTED CHUNKING OFF. I WAS ABLE TO PULL OVER AND STOP THE CAR WITHOUT INJURY TO THE KIDS I WAS TRANSPORTING TO SCHOOL. THE LOCAL FIRESTONE DEALER SAID IT WAS SOMETHING I HAD DONE, EITHER BY MY DRIVING HABITS. 4 WHEELING WHICH THIS VEHICLE IS NOT USED FOR, OR HITTING POT HOLES. AGAINST MY JUDGEMENT BOTH OF THE PROBLEM TIRES WERE REPLACED WITH NEW ATX'S. IN LIGHT OF YOUR INVETIGATION I FELT I AHOULD FORWARD THIS INFORMATION TO YOU. I LIVE IN COLORADO, OBVIOUSLY NOT IN THE AREA WHERE FIRESTONE CLAIMS THE PROBLEMS ARE AND THE INCIDENT OCCURED ON C470 BEFORE UNIVERSITY. IN DOUGLAS COUNTY. I DON'T KNOW IF THIS WILL ADI IN YOUR INVESTIGATOIN OR NOT. I AM VERY THATNKFUL NONE OF THE 4 CHILDREN AND MY SELF WERE INJRED AND THAT THE VEHICLE DAMAGE WAS LIMITED TO THE TIRES.( DOT NUMBER: VDHL1PM205 TIRE SIZE: P235/75R15 )

BOUGHT VEHICLE IN NOV. '98. HAD TO REPLACE TRANSMISSION IN OR AROUND APRIL '99. WAS TOLD BY SEVERAL PEOPLE THAT NISSAN WAS HAVING A PROBLEM WITH THEIR TRANSMISSIONS THAT YEAR. DEALERSHIP REPLACED WITH A NEW TRANSMISSION ONLY BECAUSE WE HAD PURCHASED AN EXTENDED WARRANTY. ON AUGUST 7, THE TRANSMISSION ONCE AGAIN FAILED ONLY AFTER A LITTLE OVER A YEAR. WE THOUGHT IT WAS STILL UNDER WARRANTY SO WE HAD IT TOWED TO THE SAME DEALERSHIP. WAS TOLD THAT THE WARRANTY HAD EXPIRED. THEY SAID THEY WOULD PULL TRANSMISSION TO SEE IF THEY COULD TELL WHAT IT WAS. IN THE MEANTIME, I STARTED CALLING OTHER PLACES TO CHECK ON PRICING. WAS TOLD THAT THE TRANSMISSION HAD SOME KIND OF BOLT (?) OR SOMETHING THAT WAS A DEFECT IN THEIR TRANSMISSIONS BUT WERE STILL KNOWLINGLY REPLACING THESE TRANSMISSIONS WITHOUT CORRECTING THAT PROBLEM. WE BOUGHT A NISSAN BECAUSE WE TRUSTED THE RELIABILTY OF THE MAKE. NOW WE ARE GOING TO BE AROUND $2,000.00 OUT, PLUS SITTING ON THE SIDE OF THE ROAD FOR A COUPLE OF HOURS AND THE INCONVIENIENCE (WE WERE TO TAKE OUR VACATION THIS WEEK, NOW WE CAN'T). IF THIS SITE IS NOT THE CORRECT PLACE TO MAKE THIS KIND OF COMPLAINT I APOLOGIZE FOR TAKING UP YOUR TIME. I THINK THERE SHOULD BE SOME RECOURSE FOR US. WE DO NOT HAVE A LOT OF MONEY AND THIS WILL GREATLY SET US BACK WHICH WAS THE PURPOSE OF GOING WITH A NISSAN.
