I have had my 2001 Pathfinder since Dec 6 2000. Overall I must say it has performed very credible, but after 100,000 miles my problems started.

First I was charged almost 1300 bucks to do some tune up and replace coils, should it cost that much?

My check engine light has been on for almost a year. I have failed emission test in my state of CT, I was advised it needs new cats.. but this fella told me to get my software updated since I am running about 20 versions behind. I am going to have this done at the dealer for about $95.00 bucks. A lot of dealers don't want to touch this reprogramming stuff, I don't know why. Can anyone advise if this process works?

I can't believe we all have the same problems. My clock doesn't work, slow window, I can live with that.

My issue is I've had my check engine light on since it had 62k, and now has 145k, only issue now is won't go over 70 on wot and the light flashes!! Any ideas?

Wow, I'm so glad I decided to check on-line to see if my problem could be solved easily. I'm depressed after reading all of these posts. I will say, however, that this is my third Pathfinder. The first one was totaled when we were hit broadside by another SUV. The accident spun us around, flipped onto the roof and slid 150 ft. We, my 8 year old son and I, walked away with very minor injuries considering. He had a scratch, I had a minor fracture on my collar bone.

Anyway, to get back to the problems, my second one I traded in for a newer version. I didn't have any mechanical problems with the first two. My 2001 is doing the same thing all of yours is doing. My check engine light came on months ago. Running a little rough. Then the shudder started occasionally at a red light. Then the CEL started blinking when the shuddering happened. This weekend on the way from CT. to Maine, while trying to pass on the Mass Pike, the shuddering happened and I had no acceleration, light started blinking again. I pulled over, rested for a short time and drove it back to CT. Mechanic says I have to wait for it to act up again and bring it in during an episode so they can tell what cylinder it is? I think I am going to try the advice about the multi-meter. Has anyone talked to a lawyer yet?

I also have an 01 Path. Bought it in March of 07 with 67000, now has 131300.

I drive a lot. Anyway, the service engine soon light is on almost always. The acceleration was not there after a while, so I replaced the MAF sensor. Got it at a junk yard for $267 and installed it myself, not hard to do.

Replaced the tail pipe assembly because the tail pipe fell off the rear muffler from rust; $87 plus $83 for install. BTW, use WD-40 on the bolts and they should break free. I realized this later.

Brought it to Auto Zone for the free check engine light diagnostic and it said all 4 O2 sensors need replacing for a total of 600 bucks. Haven't done this yet. Car failed inspection due to this. 2 days later the SES light turned off so I ran to inspection and it passed. An hour later it was on.

When I bought it the CD player was bad, so I had the dealer replace it. Lucky I checked it then. Other than that I've only had to replace belts, oil, brakes and tires. I'm about to replace plugs and wires and give it a tune up overall.

I love my Path, and although there are these recurring problems with them in general, they do last a long time. The engines never die and transmission seems flawless. I'm hoping for 300k plus, but that might be a stretch. Change oil every 3000 miles.

Hello all.

Update to my original comment on March 28 2009 at 19:43. So after all the hustle and bustle, I found a dealership in Ct that was willing to reprogram the computer in my 2001 Path. I am glad to report that the truck pass emission test. Check engine light is off and it runs just as good as the first day I picked up from the dealership.

Folks, don't let anyone suck you into changing cat converters and oxygen sensors first. Make sure the computer program is first updated. Happy motoring with your Pathy.

Hi All,

My wife has a 2001 Pathfinder with a ton of miles on it, we absolutely love the car. But here is the problem trying to get it out of park. Started acting up a while ago now seems like getting worst. I did read a comment before about a switch in the steering column was the culprit of the problem. Has any one changed that, and if so whats the name of the part and how much does it cost? Also did any one do it themselves and have to buy any special tools.

Thanks for the help.

Have an 01 Pathfinder running rough when hot. Check engine light on, reading 1320, 0304 and 0160 codes. I want to change the #4 coil pack to begin with, which one is #4?? I'm guessing passenger side in the middle, but don't want to do this twice if I can help it... thanks.

I have a 2001 Nissan Pathfinder SE. I've encountered just about every issue on this thread. Last year in April I had the Mass Airflow Sensor replaced and the Check Engine Light came back on shortly after wards. Now my tailpipe is broken & it bangs around when I drive, very annoying! A while back it began to die a lot. I found that the fluid in the battery was low. My brother put some distilled water in it and fixed it.

I've noticed in the last week it has begun to stutter at acceleration and idles strangely. The tachometer (I think that's what it is) will jump even while driving. Need help!!

Any advice would be greatly appreciated!!

Have a 2001 Pathfinder with all the normal issues identified (clock, slow windows and CD Changer)...car has 123K miles and have yet to have spark plugs changed... mechanic said it would cost nearly $400 since I should get the rubber spark plug housing changed, it this necessary? Car is starting to have some trouble when starting, this is probably due to the plugs needing to get changed, do you guys agree?

I own a 2001 Pathfinder LE and have had many of the same problems listed. Mass air flow went out at around 105K, and now I am struggling with the ignition coil and the code does not tell me which one is bad, so I keep resetting the code hoping the next time it goes off it will provide more information.

I did have the Err2 problem with the CD player and was able to repair it myself. If you email me (squiggyh@yahoo.com) I may be able to help you resolve that issue. I also have the slow windows in the winter and use a silicon lubricate in the fall on the tracks, and that seems to make them at least usable in the winter.
