Pathfinder SE 3.2L

  • Automatic transmission
  • 133,000 miles


On August 20 2014 the problem started happening, my daughter was merging on to the interstate and went to merge and the car did not accelerate at all. Another car swerved to miss her at 70 mph. the check engine light came on and she moved to the shoulder to avoid an accident. She was very upset and called me crying hysterically. I asked her if it would start and she said no . I felt helpless because she is 200 miles away at college. I told her to call her roommate to come get her and i would drive there the next day to see what i could do.After 20 minutes she called back and said it started. I told her to take it to the closest Auto Zone etc and tell them to run codes on the car Code came up P1774 which is bad solenoid in transmission. I went up the next day and tried to drive car home. Had a few problems but got it home. Took it to a reputable transmission shop and he told me the coolant and transmission fluid have mixed and have been contaminated. He told me he had 2 more pathfinders on lifts with the same problem. He also told me that he has had over a 100 pathfinders he has fixed over the past year. So i called nissan customer service and told me to go to a dealer and have it checked. I did and they told me the same problem and told me i need a new radiator and transmission. $ 5.000 my cost. Called back nissan and for 2 wks talked to at least a dozen people and they said sorry we are not paying to fix your problem. Even the service manager at the nissan dealer and the other shop said there should have been a recall for this problem.Please help all the people with this issue get some help.Thank You

There are many problems with this vehicle. When I checked the fluids for the transmission, it wasn't the color of the transmission fluid, it was a black color. I have also been having transmission problems. I found out that the catalytic converters need to replaced. When it was working, the vehicle would stall and then start back up. I cannot gear in (R) reverse and my vehicle cannot drive anymore, even geared up in the (D) drive. It revs up and does not go anywhere. Now I am stuck with a vehicle that does not work AT ALL. I cannot drive to interviews and take my child to school.

Something needs to be done with this. This is going to total up to thousand dollars for recalled parts. I am upset with the manufacturing of this vehicle.

  • Automatic transmission
  • 94,000 miles

The heater hasn't worked for two winters. I thought it was related to the radiator/transmission defect caused by Nissan. Each time I took it in to Nissan to check the heater, they just said they didn't know what was wrong with it. The heater would occasionally work, but mostly not. I took the Pathfinder in for a routine oil change and asked them one more time, to PLEASE look at the heater again as I cannot drive it another Colorado winter without heat. Finally they told me that the coolant and transmission fluid are mixing, due to a manufacture error (I have since read that it is caused by a crack in the radiator.. caused by Nissan) and that my transmission needs replacement and I will have to pay $3000!

This is unethical of Nissan. Nissan made a mistake, and should have to take full responsibility!!!

I have had no heater for a couple of years, in Colorado winters. Each time I took the Pathfinder to Nissan, they couldn't/wouldn't tell me why it wouldn't work. Now I know it was because of a defective radiator, that is now causing my transmission to go bad.

Pathfinder SE V6

  • Automatic transmission
  • 98,256 miles

Going through this process one Nissan representative admitted to me that they hear about this problem all the time and they are told to refuse all of them! After owning multiple Nissans over the years I can tell that this company is losing its way.

Story: This Pathfinder was Dealership serviced whole life and always ran flawlessly. Once the trans started shifting poorly at around 120K I was told it was outside of any warranty. I asked for assistance since this was a known issue and seemed to be increasing with other owners on the blogs, etc. And dealership refused and factory refused. Both very abruptly, I might add! It was obvious that they hear about this problem all the time and know just what to say. I took it all the way to "Nissan Executive Team"(highest level for factory goodwill decisions they told me) and they refused to help or participate in anyway and to complain to the BBB. I am just so very disappointed with this. I am having the trans and rad. repaired at a local Aamco trans. Hope it all works out as I still love my Pathfinder and would like to keep for several more years.

  • Automatic transmission

Noted the contamination in the cooling system overflow. Repair shop flushed the transmission, replaced the radiator ($600). Brought the vehicle home and now we are experiencing the dreaded shudder, transmission on its way to failure. Next step? User tranny with 1 year warranty is $2800 + labor to swap them out. $4K to fix this issue. I will likely NEVER purchase another Nissan.

This is Bull. Nissan appears aware of this transmission issue due to the extended warranty offered to all. However those of us with 80,000 or more miles get the shaft and have to pay out more than $2500.00. Nissan should have recalled the vehicles. Unfortunately I'm stuck with my Nissan for a few more years but when the time comes we won't be looking at Nissan again.

Pathfinder LE 4WD V6

  • Automatic transmission
  • 129,000 miles

My car joins the ranks of the victims of the radiator coolant leaking into the transmission. Started feeling rumbles at around 40 mph 2 months ago; brought it in for servicing and was told there was coolant in the transmission. Then researched the issue on internet and learned all about the now-closed class action lawsuit re the design defect that allows the hoses to transmit the coolant into the transmission. I'm afraid to drive because I know that any moment the transmission can fail completely. Was quoted "around $6500.00" to fix it. I will take it to the Nissan dealer to see if they can do better with used parts, but only if they have a long warranty. I think it's a bad idea to spend $6500 for it; why give so much money over to Nissan when they haven't taken responsibility for the defective radiator and transmission? I will request that them to cover my expenses and if they refuse I think I'll file my own personal little lawsuit in small claims court just to express my frustration if nothing else.

Pathfinder V6

  • Automatic transmission
  • 88,120 miles

At first sign of a problem it was too late...transmission fried. Extended Warranty set to 80K I'm at 88,128. This will cost me $2500 out of pocket...I'm reading on the site that average mileage of the problem is over 100K so they set an 80,000 mile mark to cost the owner $2500 which is probably less than it costs them to fix it being they are the dealer.

I almost got killed because it chose to slip and stop the vehicle in an intersection when the light changed and cars were baring down on me at 50 mph. People thought I was a nut stopping in the intersection as I tried to limp my way out of harms way.

Thanking God my family was not with me...

Can't afford this with awful economy but have no choice.

I'm pretty screwed!!!

Nissan has totally let me down...

Pathfinder SE V6

  • Automatic transmission
  • 134,000 miles

We took it to a mechanic. He said the radiator was cracked and replaced the thermostat because it all of a sudden started running hot. About 2 weeks, later, we took it to another mechanic and he said that we need to replace the radiator and he needed to drain the transmission due to the mixture or coolant and tranny fluid. My wife bought the radiator, and took it to him to fix.

After about 2 weeks, the check engine light came on. Now, I'm in Afghanistan this whole time as a Paratrooper, she'd doing this on her own with 3 children and little to no money. Once the light came on, she took it to Auto Zone to get the code read. They said it had something to do with the cat converter. When she found that out, she took it to Nissan of Sanford, NC. The service dept ran a diagnostic test and told my wife that it need about $8,000 worth of work. It needed a new CAT Converter, a new transmission and new cooling system. Keep in mind, we have already paid more than $1000 putting a "band aid" on a more intense problem.

The service man at Nissan told my wife it is a ticking time bomb and that needed to get rid of that vehicle while it was still drivable.

Little did we know about the class action lawsuit for this vehicle. The Nissan Radiator Defect Class Action Lawsuit Settlement case is In re: Nissan Radiator/Transmission Cooler Litigation, Case No. 10-cv-07493, U.S. District Court for the Southern District of New York.

Now after reading all the disgruntled owners talking about "What about the owners over 100K". This is blatant disregard for loyal customers who apparentlt, HAD THE MISFORTUNE of their vehicle"MAKING" it past the 100K mark.

This is a skid mark on the underpants of an owner. Shame on you. Now, I'm stuck between a rock and a hard place...either try to fix the issue and spend 8K, or have my wife trade out while Im in Afghanistan, deployed, sacrificing my time, my life for asses like Nissan to just crap on us. I can't believe this is happening.

  • Automatic transmission
  • 108,000 miles

I have heard that several people are having problems with their transmission fluid getting radiator fluid in it. The classic signs and symptoms that have started with my 2006 Nissan pathfinder are: 1. horrendous shuddering when pressing on the gas to increase my speed, 2. occasional banging when my automatic car shifts into gear, 3. delay in speed when I attempt to pass. since all of this had started right after 100,000 miles a new transmission is not covered. I am a single mom who is a hospice nurse, I drive all day, having a reliable car puts food on the table for my kids. I don't have $3,000 to fix this problem. I could cry, I don't know what I am going to do. right now I just keep driving it knowing it is going to break down any day. I was informed by so many people that Nissan was a great company and manufactured a great vehicle when I decided to by this pathfinder. I am soooo disappointed!!! I will never buy another Nissan vehicle, I'm sorry, for the amount that I originally paid for this vehicle, it should not start falling apart at 108,000 miles.

Pathfinder LE V6

  • Automatic transmission
  • 89,900 miles

On the Nissan website it stated that beginning in October 2012 they were going to start notifying owners of pathfinders from years 2005-2010 via mail about the changes in warranty and the extension of the warranty due to the defective radiator. I never received any sort of notification. Furthermore, the defect is not occurring until the vehicles are reaching 80,000 plus miles. extending the warranty to include up to 80,000 miles does NOT affect or help the MAJORITY of owners. Most vehicles made in the years affected are just now starting to reach this level of mileage. I would expect there to continue to be issues with the defective radiator as all of these models continue to "age" and the mileage increases. This isn't going away!

This is a Nissan manufacturing issue; we should not have to pay a dime for the repairs. I'm a teacher and I work very hard to pay for my 2006 pathfinder, which is ironically close to being paid off. It's not fair to have to incur these very, very expensive additional costs just to maintain a car I have taken very good care of over the years. Dear Nissan, take responsibility for your mistakes. Make it right!

I noticed a shudder when the car was shifting, My mechanic test drove it and sent me to the transmission shop. The gentleman there told me that it was a transmission problem. He also said that this was a common problem with this year Pathfinder. He thought that since this was a common problem that Nissan had extended the warranty. I later found that the warranty had been extended but not enough to include my truck. Very disappointed in Nissan, I have owned 4 Pathfinders and several other cars made by Nissan. I thought they would take better care of loyal customers.

My frustration is there is no manufacturer recall created after the issue was brought to their attention in 2012. The appropriate course of action by Nissan would have been to issue a recall. Instead, those of us that were never alerted to the issue are now covering the bill. Everyone is up in arms about GM. However, what about the companies, like Nissan, that fail to do anything? At least GM was able to swallow their pride and take care of their customers. I would assume that most people will feel the pinch when they have to spring thousands of dollars to fix a vehicle, with an issue that cannot be ignored.

  • Automatic transmission

Had my 2006 Nissan Pathfinder LE serviced at the dealership on March 2014 and had the transmission fluid changed because the service managed said that it looked bad. My Pathfinder was making a noise similar to running over the rumble strip on the side of the road. It stopped after have the fluid changed for a while. The noise returned and I started to read on line about the radiator problems and checked my radiator and found a milky reddish color in it. I now have to put out $2500 to have radiator and transmission replaced because of a know defect in the radiators which Nissan did not recall!!!! If it is a know defective part & Nissan knows about it they should be responsible for paying for the cost of the repairs. What a crock of sh*t. I owned Nissans for the last 20 years because they were very reliable. Not pissed of about the problem, I am pissed off about Nissans no owning up to the problem and making things right. PURCHASED MY LAST NISSAN !!!! A word to everyone out ther is Nissan does no give a SH*T about its customers!!

Everyone needs to get together and file a class action lawsuit against Nissan. Maybe if enough people get in on it they will have to do something. The National transportation and Safety department has been working on this for a couple of years but said they didn't have enough people to complain. SO people, let's get on it. There was a class action lawsuit against them last year but of course no one bothered to let me know. Apparently none of you knew about it either. I say blast them on CNN and every other news station that we can get it on.

Pathfinder LE 4.0L V6

Well, unfortunately we fell victim to the infamous coolant/transmission cross contamination. We purchased the 2006 Pathfinder in 2009 from Nissan dealership with approx 46,000 miles on it. This was a certified used vehicle and until this problem we haven't had any. What makes this so bad is we still like the Pathfinder, very comfortable nice vehicle. But like so many others we are UNHAPPY with the way Nissan has handled this problem.

We had the transmission and radiator replaced and so far so good, drives and runs like new. But it shouldn't have cost us a dime! Nissan knew about this problem and should have been proactive and recalled before a Class Action Suit was taken out against them! I'm very disappointed in them for that. My family have owned several Nissan's and they have always been dependable vehicles but I would have a hard time recommending anyone buy a Nissan now. And seeing the problems of the new design Pathfinder with the CVT I def. wouldn't have one. I hope and pray that there is enough complaints that they reimburse the "copay" $2500 to us for having to replace radiator and transmission with only 88,000 miles!
