2002 Nissan Pathfinder Engine cooling Problems

“Exhaust system problem on 2002 Nissan Pathfinder. Just paid $645.00 to have two co2 oxygen sensors replace on vehicle and then was told that I needed to have my resonators replace in order to pass the emission control test. I have been smelling emission from the car for a year and was informed that it was co2 sensors that need to be replaced.”

“I own a 2002 Nissan Pathfinder with 97,000. Miles on it. There is a crack in the exhaust manifold that has been getting louder over the last 24 months and recently I have begun to smell exhaust inside the car. This apparently is a manufacturing defect and should be corrected by Nissan.”

“Both catalytic converters seams blew out which made the oxygen sensor go bad. I called Nissan dealer in jamestown n.y. To see for recalls, he said there was a service bulletin. They had me bring vehicle in and they cemented the seals. They said they had many complaints on them, and had a kit to fix them, they charged me $150.00 to fix it. Which lasted about 5 months ,and they blew out again.”

“The exhaust resonators on my 2002 Pathfinder began to leak at a welded seam at about 28,000 miles. The Nissan dealer refused to replace the exhaust pipes and insisted on installing a patch kit. This kit only lasts approximately 20,000 miles and they begin to leak again. This repair has been performed 4 times thus far and it is leaking again. Truck now has 103,000 miles. Nissan now refuses to pay for the patch. My service engine light is now on so I suspect this is tied to the exhaust leak. …”

“Details: we have been loyal Nissan customers since 1987 and my 2002 Pathfinder started making a loud rattling noise. We had it towed to the dealership and the technician checked it out and told us that 2 screws had fallen out of the power valve and were bouncing around in the cylinder, and there was nothing we had done wrong. It is a design flaw that Nissan refuse to correct. I am told it could have been corrected for $150.00. The cost of repair the Pathfinder is $7,899.99 which Nissan north american has refuse to pay. …”
