Automatic Transmission problems of the 2006 Nissan Pathfinder

Transmission and radiator fluids mixed and caused a major lock up and overheating in the car. The transmission was destroyed and the radiator needed to be replaced. Nissan is aware of the malfunction but failed to notify or do anything about the issue. This is not only a safety risk, but a mechanical risk to the owner and Nissan should at least notify the owners of this potential risk.

Nissan 2006 Pathfinder needed a new battery. Changed the battery and took for a test drive. Very sluggish from zero to 30 miles per hour. Not able to accelerate at all. Was told I needed a new transmission but I was 6,000 miles over the warrenty, so Nissan said too bad. I do not understand why a car with 86,000 miles needs a new transmission. Why is Nissan not standing by their product? if this is a common problem why is Nissan not standing up for their customers?.

We need to look into the transmissions on 2005 and 2006 Nissan Pathfinders and frontiers. Finding several other people who have experienced the same issues. It seems to be a bigg problem to the tune of over $7000.

Radiator was leaking but did not cause any over heating issues with the car but it did cause the transmission to break and now needs to be replaced they say its a defect in the radiator.

While operating the vehicle, moderate to heavy vibration occurred followed by an extreme loss of power. Thankfully I was not on an expressway. Took to dealer and was told transmission was contaminated with coolant, requiring a replacement of the radiator and transmission, approximately $5,000. While there, it was inferred that this has been a recurrent problem with this model. There were 2 other vehicles there that day with similar complaints. The dealer (first team Nissan) has submitted to Nissan north America a request for some relief. The vehicle currently has 100,000 miles on it, but I believe strongly, based on various web searches and some complaints on this site, that there is a manufacturing defect that needs to be addressed. I have not heard back from the dealer or the manufacturer about this. The dealership said they handle these on a 1st come 1st served basis and he believes they have a very large back-log of complaints. The problem was diagnosed by the dealer may 3, 2011.

The contact owns a 2006 Nissan Pathfinder. The contact stated that while attempting to place the vehicle in gear the vehicle did not accelerated over 20 mph. The contact mechanic inspected the vehicle, the failure was located at the radiator water penetrated the transmission. The vehicle will be taken to the dealer. The vehicle had not been repaired. The failure and the current mileages were 71,000.

This is in reference to the 2005 and 2006 Nissan Pathfinders and the failing in-radiator transmission coolers allowing coolant into the transmission causing them to fail. My 2006 has not failed but I am replacing the radiator today to stay ahead of the potential failure. (I am a mechanic and after reviewing approx 200 internet posts see the issue very clearly) you are welcome to the radiator I will be removing for a forensic evaluation of the internal transmission cooler, I have maintained my vehicle religiously and this would be a good indicator if there are corrosion issues with proper maintenance and low mileage. Just let me know where you would like it sent.

The contact owns a 2006 Nissan Pathfinder. While driving approximately 15 mph, the vehicle stalled without warning. The vehicle was towed to an authorized dealer where the contact was informed that the inside of the transmission had become milky with metal parts. The vehicle was not repaired. The failure and current mileage was 86,000.

I purchased a 2006 Nissan Pathfinder off the showroom floor at my local Nissan dealership in July 2006. In August of 2006, the fuel pump assembly had to be replaced. In 2007, the fuel level unit had to be replaced. In 2009, the fuel module had to be replaced. Now, the transmission problems have begun. The dealer refuses to repair even though they are aware of numerous complaints from Pathfinder owners. I am out of money and patience with this vehicle. Nissan should issue a recall.

05 & 06 Nissan Pathfinders got a bad batch of radiators that were installed into there cars. The radiators are cracking and allowing the coolant to mix with the transmission fluid destroying both and leaving consumers with repair bills between $5500. 00 and $7500. 00. The danger in this matter is that cars are over heating on the roads, and transmissions are failing during driving. How safe can it be when a car is traveling down the road and complete loss of power happens at 70mph in the fast lane or in a steep incline. If your lucky enough to get to the shoulder safely then a family with kids could be trapped on the hwy or back roads of America forced to walk to the nearest town putting them in extreme danger of being run over and killed. Also if a car overheats and someone tries to force it down the road to a town that car could catch fire. All due to Nissan putting these radiators into there suvs knowing its a family car. Nissan north America refuses to acknowledge the problem putting 10s of thousands of lives at risk.

Nissan 2006 Pathfinder models come with defects that Nissan will not take responsibility for. The fuel sending unit on this vehicles are defected and can cause people to run out of gas and put themselves in danger. Also the radiator can cause a leek and send fluid into the transmission causing possible accident. Nissan refuses to admit this is a recall problem.

In November 2008 I purchased my 2006 Nissan Pathfinder se from a private owner. There were approximately 42,000 miles on the vehicle. After having it inspected, I was told it was in great shape and for 1 year I drove it with no significant problems. In November 2009, the gas gague began registering empty when it was on a quarter tank. The dealer replaced the fuel sensor ($400) which resolved the problem. I later found out that there was a recall on the same make/model and for that exact problem just 3 monthes after I had mine repaired, but because my VIN# was not on the recall list, I was told my money would not be refunded . Not long after this incident with 58,000 miles on my vehicle, I started having transmission problems, I was told by the dealership that even though my transmission is covered up to 60,000 miles, because the problem originated from a faulty seal on my radiator (only covered until 36,000 miles) that leaked antifreeze into my transmission, my transmission repairs were my responsibility. I call Nissan corp. To report the problem and the representative informed me that Nissan has received multiple complaint calls form owners having the same problem with the same vehicle. She advised me to voice my concerns to you in hopes that you could reslove the matter.

The 2005/06 Nissan Pathfinder has an issue with the radiator (coolant) leaking into the transmission. The defect causes the car to smoke once the transmission has completely gone out. This also at some points causes the car to switch gears violently on when going above 60 mph.

Transmission stalling vehicle making vehicle jump. Called Nissan motors about transmission problems. Have read on boards this problem with transmission and radiator is very common in these vehicles. Vehicle just all of the sudden starts jumping which could cause an accident. Paid too much money for this Nissan to be having these kind of problems and do not want to cause an accident. Nissan is not cooperating with all the consumers that own these vehicles. I am afraid it is going to completely stall in the middle of the road.

Nissan Pathfinder, 2006 dealer states radiator coolant leaking into & mixing with transmission oil. Car would have a severe vibration above 40mph approx. When changing final gear. There is no heat from heater. Car temp would rise at speeds over 40mph. Dealer asked for $8000 for replacement of radiator and transmission. Car under power train warranty but they still won't cover defect radiator. Common problem found online with 2005 & 2006 models, they can catch on fire and the service engine light is not turning on. Nissan hq declined any help.

We have been having problems with our vehicle "shaking" at 40 mph and again at 60 mph. We have had it into the shop to be looked at but after replacing u-joints, some other items and putting new tires on our vehicle it didn't get better. My wife was driving our Pathfinder home one night with our daughters in the vehicle and noticed that the vehicle was sputtering. She thought that possibly she was running out of gas although it was showing a 1/4 tank but we had been noticing that the gas gauge would fluctuate when we would fill the vehicle up (something that we noticed other Nissan owners have mentioned as well). She stopped at the gas station and noticed that the vehicle was overheating. We had it towed to a Nissan dealership where they told us that the radiator leaked into the transmission and we were going to need a new radiator and new transmission. We are over our miles and our warranty has run out. We have contacted Nissan but were told that they are not obligated to fix anything or pay for anything since we drove our vehicle outside of our warranty and have put too many miles on our vehicle. We have been reading that this is a problem with the 2005 and we are thinking that this is going to be the same case for the 2006 and 2007 once the miles get to about 60,000. We have heard that Nissan has put out a bulletin on this problem and are aware of it but as the regional manager told us, they are not obligated to fix or pay for anything outside of the warranty. They know this is an issue and still they are not doing anything to make good on a product that has a manufacturer's defect. I'm sure that they are not interested in hearing this and have probably heard it before, but we will not buy another Nissan product and will make sure that we let as many people as we can know that Nissan does not stand behind their product.

: the contact stated while the vehicle was parked in the driveway, a popping noise was heard. While the vehicle was rolling backward, a ticking noise was heard. It rolled out of the driveway and clipped another vehicle causing minor damage. The vehicle came to rest across the street from the contact's driveway. A passenger had a minor injury to the arm. The vehicle was towed to the dealer who could not identify the problem. Updated 10/30/06.

I own a 2006 Nissan Pathfinder. After hearing about many transmission issues due to a faulty radiator/seal, I decided to be proactive since I only have 41,000 miles and one year remaining on my power train warranty. I called Nissan USA informing them of my concern, and to see if there was a fix in place before my warranty was up in one year. The woman informed me that unless there was a specific problem at this time, nothing could be done. I was calling to try to save them from an upcoming issues/repairs under warranty. I also called my local dealership, and he heard about the issue and stated that no fix or recall is in place. After owning multiple Nissans over the past 15 years, this new was disheartening. Nissan documented my call (I have a conf. Number). I already had u-joint replaced. Alternator tensioner, and timing chain replaced under warranty.
