Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2005-2007 Pathfinder appears to have a widespread defect where coolant leaks into the transmission, causing transmission failure around 90,000 miles. Repair costs are typically upwards of $3,500.

According to the New York Times & a class action lawsuit, the defect actually extends through 2010 model year. More info here.

  • 78,000 miles


I purchased my Pathfinder used. With 78,000 miles and within 10 days of having it the transmission dropped completely. Well we took it to the dealer and demanded they make right..they paid our extended warranty never paid for our rental car and never bothered to tell us there was a defect on my vehicle! we were driving and noticed the transmission slipping and the truck vibrating very loud and vigorously when going into 3rd or 4th gear at around 50 mph. But they had told me it was my imagination. Well 10 days from the day I drove it home I guess it wasn't just my imagination because we lost all acceleration power. The truck was running but wouldn't not move. Here I am a year later googling why my truck keeps screwing up and boy what do I find"??" I'm very livid and can't believe that Nissan has decided to fatten their wallets instead of helping it's consumers and making things right. I had a new transmission and new radiator put in. And a year later I'm fighting the same problem all over again. If I'm idle or stay in one spot for a few minutes my truck is over heating and not only that but it's spewing coolant out the reservoir. I have had it in the shop numerous times and no one gives a crap! I was told it was an air pocket and I'm not stupid especially now that I'm reading all the other complaints. This makes me wonder how the government can allow this to continue going on..I can't believe that no help is available to us and we are being screwed royally and our lives in danger because we are forced to drive a dangerous non reliable vehicle!!!!!!! make things right Nissan fix our vehicles or do a recall and give us our money for putting us through [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Milky substance appeared in radiator and car smoked and smelled. Took to mechanic and reported failed cooler causing radiator fluid and oil to mix. Resulted in cracked heads as engine overheated. Now transmission has failed. Likely due to engine overheating.

We started to have a very loud and creeping noise when we put the car in reverse. Sounds like we were pulling something very heavy and the car could not resist it. Then, we also started to notice issues such as a delay in gear changes and more noises now when driving forward or in reverse. We took the car to the dealership today and they diagnosed it with a "broken trans cooler line in radiator which made the coolant leak and mixed with transmission fluid. They want us to replace the entire transmission, radiator, and flush engine block bringing the price close to 7K. I started to research this and I'm definitely adding my complaint and will surely call Nissan to see what options they will give us. 2/20/15

I was driving on the expressway and my car suddenly would not accelerate. I made my way to a street location and pulled my car on the side of the road. I shut the car off. It would not start. I had it towed to a mechanic and he said that it is the transmission.

Pathfinder 6-cyl

  • 111,349 miles


For the past week when ever I drove my car the entire vehicle shudders, shakes and has a harsh upshift when it is changing gears. It happens the most on highways going at high speeds (55-65 miles). I took my car into a Nissan dealership on 1-29-14 to get it checked out. The dealership diagnosed my car with a "broken trans cooler line in radiator which made the coolant leak and mixed with transmission fluid. Advise replace entire transmission, radiator, and flush engine block as well as replace thermostat, (price to fix: $5938 + 9% tax)". I researched this issue online and found this to be a common defect issue that Nissan has been dancing around since 2007, as well as a class action lawsuit being filed against Nissan. I bought the car on July 28, 2011, so I have only owned the car for a little over 2 years in which the dealership I purchased the car from did not inform us of this warranty being offered by Nissan from the lawsuit or informed us of the possible transmission problem. I had the car completely checked out by a mechanic in November of 2013 and it passed with no issues. Now here we are 2 months later, and over 100,000 miles and my Nissan experiences this issue. This can be a very detrimental and dramatic failure, causing massive safety issues if I continue to drive my car, especially on highways going high speeds. I contacted Nissan this morning to see if they are going to stand behind their product and since I am only 11,000 miles over their "warranty" (which has high deductibles), they denied to help and I am left holding a $6500 price tag to fix my car.

Was hearing noise from the engine, dealer diagnosed as timing chain guides bad, said this was a "known" problem with this model. 3 weeks after fixing was going to work and the transmission went out, was advised by dealer that coolant had leaked into the fluid from a faulty radiator design on this model...estimated 6000+ for repairs. These are known issues with this model Nissan and the company has offered zero help with correcting this.

Pathfinder 6-cyl

  • 126,000 miles


Calsonic radiator issue - transmission fluid and coolant mixed causing issues with transmission. Bad transmission cooler area per aamco. Nissan is unwilling to help as my vehicle has 126K miles on it. These issues appear to be happening in a much greater % than Nissan is acknowledging. They moved the warranty from 3 yrs/36000 miles to 8 years/80000 miles but it still doesn't help those whose radiator leaked after the 100K level prematurely. This is a safety issue and also a manufacturing defect issue. It seems that Nissan corporate, dealers, transmission shops and other governmental organizations knew about this issue - sadly, most consumers don't. I would have gladly replaced my radiator for $500 but now I will be out $4000 because Nissan didn't tell their owners about this problem.

Pathfinder 6-cyl

  • 107,000 miles
Note: Affected parts are transmission and radiator (not sure what category those fall in) I purchased a 2007 Nissan Pathfinder from a Nissan dealership less than 3 months ago. Immediately after purchasing I noticed what seemed to be a minor lack of power or cutting out when coasting downhill. I mentioned it to my sales rep, and again when I had to take the vehicle back to the shop on two separate occasions for a tire pressure gauge and rear door handle problem. I had never owned a 4WD before and it was dismissed as no big deal since it still drove okay. Then last week, over labor day weekend, my car overheated and immediately discharged a grey milky substance from the radiator without warning. It had not overheated prior to this. I had my car towed to the dealership. They informed me that both the transmission and the radiator need replacing to the tune of $6,600. The cause being the radiator fluid leaking into the transmission. This repair is over half the value of the car. I never would have purchased the vehicle had I known about the defect. At a minimum I would have insisted it be covered by warranty. I paid full retail price for the car not knowing of this defect. While I'm grateful no one was injured by this defect this time, I have no means to pay the repair costs and owe $13,000 to the bank for a vehicle I cannot drive or resell.

Major vibration during shifting gears (transmission). Concerned that coolant has leaked from radiator into transmission as has been reported on thousands of other Pathfinders. Nissan should be forced to recall and replace radiators/transmissions.

My vehicle began to drive sluggish as if it was going to cut off. When I got to my destination and tried to crank my truck to leave it would not say a word. I had my vehicle towed to the Nissan dealer in morrow for a diagnostics testing. I received a call the next day stating that the radiator and transmission had failed and it needed to be replaced in order to get the truck up and running. I explained to the dealer that I had M vehicle serviced less than a month ago and there was never an indication that my transmission was failing. They quoted me 6,100 to repair my truck. I had my vehicle towed and sent to aamco transmissions, where they diagnosed my truck as needing a enginecontrol module. My issue with Nissan is that there has been several complaints similiar to mine and they offered no help to resolve my problems. I would really like to speak to some one directly about my issues as there are too many to list here.

About 2 weeks ago I was driving my 2007 Nissan Pathfinder (automatic), when I try to accelerate a bit the vehicle show signs that the speed-gear will not shift properly. When I am at a red light also for example once the light change to green the car take a few seconds to accelerate to the proper speed making it an inconvenience for other cars behind me since the speed will not pick up on time. Sometimes also it tend to " shot" making a weird not before resuming proper speed and this happen mostly on local roads.

We noticed the Nissan starting to jerk on the frwy and service engine light came on. Took it immediately to the mechanic they gave me bad news appearantly the transmission had radiator fluid in it. He said he had seen this problem before many times his exact word were the way Nissan designed this particular vehicle causes this. My mechanic had to replace radiator flush the whole system put new fluids in total cost $976.oo he advised me to take it to a transmission shop because he said it needed to be looked at by a specialist since he could not guarantee it would not happen again or if even the transmssion would work. Well it worked but the service engine light came on on the way to the transmission shop once they got done with it and replaced everythin that needed to be fixed on the inside of the transmission I paid $3227.49. According to everything I read this can hapen to the Pathfinder without any prior problems. We took pretty good care of ours was a great vehicle till we had to dish out almost 5K after we had just paid it off. I will never buy Nissan again!
