I own a 2001 Pathfinder 3.5 liter, and only problem I've had was my A/C is shot. Replaced the condenser because it had a hole, then recharged the A/C and my compressor purge valve was spraying Freon everywhere and not blowing cold air.. replaced my compressor and nothing; both high and low side are warm; one side should be ice cold. Anybody have this happen or know a fix? Don't know what to do next, it's cost me 1000 for a new compressor and 600 for a condenser. Not to mention the shop bill for recharging and vacuuming 10 different times..

Other than that, I bought the vehicle used with 198000 ks on it and I've drove it all this time, and only changed the oil every 2000 ks and had to change the front brake pads once. I've changed the fuel filter just for sh**s and giggles.

Oh and the winter tranny slips, but I read up on that; it's a sensor reading its fluid is too cold and it's to protect the tranny from over working, so after it's running a few minutes or longer, it works excellent, but it takes awhile like 20 ks of driving.

I have 240000 kms on it now. She still works awesome; not a single time my engine light came on. I drive it hard, not to mention, I think all you Nissan haters just only know how to baby them, LOL.

Wow, I thought maybe I just had a lemon, but after reading all of these posts, I know it's not just mine!

I bought an 01 Pathy with about 87k KMs about 4 years ago. It ran well the first 3 years, but now with only 187K KMs (116K miles) on it, I seem to have all of the known issues! Clock, CD Player, rough running, coils, slow windows etc... etc...

I've replaced 3 of the 6 coils, which did help the rough running/check engine light, but as usual it came back on!

Now after it sits for 8 or more hours when I go to drive away and I push the gas, nothing happens! It hesitates... tries to go... pauses, bogs down. I find if I put it in neutral (or in park before leaving) and pump the gas a couple of times, it seems to help this issue.

From everything I've read here, I'm going to check and make sure the computer is upgraded to its latest version, then the mass air flow sensor if that doesn't help.

I'm also going to attempt to fix the clock myself using the instructions I found here:

I've just written off the CD player.

It's been a good truck, but I think it might be time to get rid of it. The fact that there are so many people out there having the same problems; I know it's a Nissan issue! There really should have been recalls on some of these issues!!! Anybody reading this a lawyer?? I think there needs to be some action taken! As a result of seeing the number of other people having the exact same issues, I think this will have to be my first and last Nissan vehicle!

I have had my 2001 Pathfinder LE since Aug 2000, and find many of the listed issues of other owners, including:

Slow windows (my front passengers window will not auto up but return down about 3 -4 inches)

My clock has gone out about 4 yrs ago (quoted $250.00 to fix at dealership -- NOT).

Had all six ignition coils replaced ($600.00).

Had the mass flow changed out.

Had the O2 sensor changed out.

Replaced all muffler parts, had two batteries, and 2 sets of tires.

Overall a good truck, however, the check engine light ticks me off as it has just come on again, prompting me to place tape over the indicator, but now has mysteriously gone out (burnt out light?)

New issue is the auto open sunroof -- the roof now opens about 2 inches at a time. Nothing that worries me.

Here's to another 125,000 miles.

This car is a piece of garbage. The service engine light is always on, even after costly repairs. Now having problems with O2 sensors, the coils and the cd player.

I got a car three years ago, I don't understand why at that time a couple wanted to sell as soon as possible. I thought they really needed money. I got the Nissan Pathfinder with all the money I had. Now it disappoints me so much. I regret buying this car. I hope Nissan help repair the car for a good price. We don't want to dump a car after ten years, is that right? We hope keep it longer, especially the signigant car in your life. I hope teenagers know about this problem and don't make stupid decisions like me.

Thanks for the information with MAF sensor and how to get it from everythingnissan.com with the correct part #. My 2001 Pathfinder experienced the same problems, such as not reaching the speed 2250 RPM, and the engine started jerking. Idle speed higher, and the idle speed sometimes fluctuates at a stop light. Changed the MAF sensor yesterday, and it now runs fine. Thanks again.

I have a 2001 Nissan Pathfinder SE. The main computer keeps burning out. I replaced it with another computer from the junk yard out of a 2001 Nissan Pathfinder, it lasted a couple days and then I had the same problem.

I wonder if I need a new computer? Help.

Bought a 2001 QX4 (Pathfinder equivalent) with 119K on it in January, and did my usual once-over: changed belts (squealed), shocks, struts, oil, filters. The car accelerated stronger through mid-range than higher RPM, flat acceleration higher up. Thought that was the way that the car was - a bit disappointing. Until we bought a second QX4 in April for my wife, same year, but with just 60K miles.

I read a post on another forum that recommended cleaning the MAF, so decided to give it a shot. After taking it off and taking a look at it, I was doubtful, no obvious residue or visible dirt. Sprayed it off anyway with the MAF spray and let it dry completely before reinstalling. Wonder of wonders, it felt like it gained significant power above 4000 RPM. Not quite up to my wife's car, but within spitting distance.

Now my wife's car's SES is on and she said there were a couple of rough idle episodes (intermittent). The tester read P1320 and P0304. Changed out the #4 coil and erased the codes. SES came back on within a few miles of driving, although the car runs fine. Only showing the P1320 code so far. Figured I'd see if the rough idle returns or if the second code comes up again.

Open to suggestions of course, thanks!
