2002 Nissan Pathfinder Engine problems

Nissan power control valve loose fasteners: my concern resonates with consumer safety that involves gross engine failure during operations due to loosening internal fasteners/components. While driving on a city street, I noticed an abrupt and unusual mechanical grinding sound coming from my vehicle (v6 pathfinder). Eventually the car would not start. After having it towed to the dealer for diagnostics and service, the technician noticed that an internal power control valve was missing from the intake after he...

Tl* the contact owns a 2002 nissan pathfinder. The contact stated that the vehicle failed to start and the check engine warning illuminated. Prior to the failure, the vehicle stalled. The failure recurred several times. The vehicle was taken to a dealer for diagnostic testing. The technician diagnosed that the oil pan was faulty. The failure mileage was 108,000.

The first time while driving the pathfinder in regular driving conditions, the engine stalled at approximately 30 mph. To restart the engine I had to put the transmission in neutral and turn the key all the way off and then restart the vehicle.The second time this happened I was driving again the same day, cruising along at about 50 mph in traffic, and the engine died again with no warning. The instrument cluster showed all the typical "dummy lights" after the engine failed the first two times. When we parked the...

Part from butterfly valve came loose and fell inside engine. Destroyed engine. *Tr

I have had the pulley repaired on my 2002 pathfinder repair twice, in 2006 and again in 2008 I believe. And it is still giving me a problem. The driver seat motor will not move forward or backward, and in extreme hot weather, my motor drags, and it is hard to start the engine. The cd player never work right. *Kb

Recently, our 2002 nissan pathfinder had to have an engine replaced. The cause was a set of very small bolts in the butterfly valve assembly which is now a part of the intake manifold. My concern is that the engine shop tech now performing the engine replacement mentioned that he is seeing a lot of this type of problem with these specific engines. Also, this is the second 2002 pathfinder we have had this happen to. The other one was my daughter's. I am an operations research systems engineer and know that the...

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. *Tr

1: Events leading to failure: 2002 nissan pathfinder, 71,000 miles. Loud exhaust sounds. Dealership looked at car (charged $50 to look) and reported the exhaust system pipes going into the catalytic converter are cracked - again - already repaired once. Dealership will not repair/replace without charge. This is a recurring defect and possibly an emissions problem. The pipes carry exhaust from engine into catalytic converter and muffler and they are leaking and this is not the first time for this vehicle or...

1. Exhaust leak sounds, exhaust into cab of vehicle, loud rattling sounds while driving. 2. Noticed around 60,000 miles, progressively getting worse! 3. Taken to nissan, nissan refuses to pay for defect. Nissan claimed cracked pipes, no recall. *Tr

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. *Tr

I have a nissan altima with 88.000 Miles on it this car it should be just getting broken in just got done paying this car off it cost me around 18,000 dollars in 2004 paid it off in june 2009 thinking I could get back on my feet again but I see that wont happen not with a bad defective catalytic converter and a ruined engine that eats antifreeze and drinks oil that's just some of this cars issues poor heat or no heat in winter I cant believe with all of the complaints on all of the nissan sight nothing is being...

I have a 2002 nissan pathfinder. The vehicle developed an exhaust leak about 2 years and 30,000 miles ago. The vehicle now has 100,000 miles on it. You could smell the exhaust leak and hear the exhaust leak. The leak is coming from the resonators or catalytic converter, whatever you want to call it.Figuring that my warranty was up, I had the vehicle fixed at my own cost. Recent investigation into website complaint forums made me realize that this has been a recurring problem for 02-03 nissan pathfinder owners and...

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. This is a safety concern as it allows exhaust gases to come from underneath the vehicle and enter the cabin when sitting idle. Based on local dealers own admissions, this is a design flaw. *Tr

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...

I am complaining about the exhaust system on my 2002 nissan pathfinder. I had a leak at the bottom of the pipe at what looks like a catalytic converter. I paid nissan to fix the problem. A year later it is leaking again. I brought the car back to be repaired. They told me the part on the bottom of the pipe is not a catalytic converter. I was told by a mechanic it was. Either way this seems to be a large problem and should be fixed by nissan. *Tr

Nissan altima - check engine light came on november 2006. Nissan dealership stated that the catalytic converter sensor could be bad and not necessarily the part. They shut the light off and sent me on my way. The light continued to go off and on over the course of the next year yet passed a state emissions test. No other engine problems occurred. November, 2008 vehicle failed state emissions test - told it was the catalytic converter. Nissan dealership states the warranty ran out at 80k miles - the car has 83k miles. Have not had the car looked at by dealership mechanic yet for fear the estimated $1000 repair could turn into an engine replacement at a much higher cost. *Tr

I have a 2002 nissan pathfinder with 67,000 miles. According to my mechanic, my two rear catalytic converters are leaking co2 from their seams. According to my service manual, catalytic converters are covered under the federal warranty 8/80. I took the car to the white plains nissan dealer and was told that it's the exhaust tubes that are leaking. The service manager said it could be repaired but I would have to pay. I understand that this has been an ongoing and frequent problem with 2002-2003 pathfinders and that...

Tl*the contact owns a 2002 nissan pathfinder. The contact heard a loud noise coming from her vehicle. In addition, the engine warning indicator illuminated on the instrument control panel. She took her vehicle to a local repair shop and the technician stated that the catalytic converter was split in the middle. She took the vehicle to an authorized dealer and they stated that the resonator needed to be repaired instead of the catalytic converter. The repair would cost over $1,500. The vehicle has not been...

Cracked resonator/catalytic converter at 60k miles. Was told that the parts were no covered by nissan, that there hasn't been a recall, but to purchase a 'fix' kit. It appears that this is common with the pathfinder and nissan will not recall the items. *Tr

When we purchased the car used in sept 2007, it had 24,509 miles on it. The exhaust sounded somewhat loud but not too abnormal. Just under a year later, the exhaust was very loud and rattling. We took it in to the nissan dealership and they told us the front exhaust tubes were rusted and leak. They said nissan supplies a 'repair kit' to put a patch on these tubes. The dealership told us they have seen many other problems like this and I have found there are many entries for this exact problem on online...

Rumbling sound coming from exhaust. Local repair shop said it was a leaking catalytic converter. Took it to nissan dealership. They said it was a cracked tube in the exhaust and there was a service bulletin classification fe04-002. Reference ntb04-092. Issued 9-1-2004. They would not repair under warranty. My subsequent research found numerous complaints about this, mostly safety related, several people suffered dizziness while idling. I believe this is a safety issue and a defective product and should be recalled. Their fix is to clamp a patch on to the leaking area. Many of the reports I read said that this also fails. I would suggest that their solution is a failure also. *Tr

Tl*the contact owns a 2002 nissan pathfinder. While driving 55 mph, the check engine and oil lights illuminated and the vehicle stalled. The contact coasted the vehicle to the side of the road, and it began smoking. The dealer stated that the vehicle was just overheating and not to worry. A few minutes later, the contact was informed that the vehicle was on fire. The entire front end of the vehicle burned to the ground. The fire and police departments arrived and the fire marshall had the vehicle towed to a junk yard. A police report was filed. The contact took pictures of the damage. The vin was unknown. The failure and current mileages were 102,000.

My 2002 pathfinder has a overheating problem. It began approximately 2 months ago. While going down the interstate the engine temp. Rose and the cruise control malfunctioned. A local mechanic noticed the a/c compressor going bad, replaced this and problem still continued and became more frequent. Mechanic pressure tested radiator, it seemed fine, found two very tiny leaks, sealed them, put on a new radiator cap. Problem still continued. Took the vehicle to a nissan dealer. They replaced fan clutch. Still...
