2006 Nissan Pathfinder. Consumer states fluid is leaking through to the transmission the consumer stated radiator fluid leaked into the transmission fluid.

I purchased a 2006 certified Nissan Pathfinder in 2008. I was guarrenteed 100k engine and power train warrenty. I currently have 96,426kmiles and the transmission gave out about 1 month ago in saline KS. I took the car to the Nissan dealer in kansas and was told that it would be covered. However after waiting over a month for the part Nissan stated that the transmission gave out because of the transmission cooling system leaking therefore the transmission is not covered. I have contacted Nissan corp directly and have received the same answer. This is hazardus because the transmission gave out without warning during a snow storm. Lickly the car mannaged to coast to the side of the road. I had my car shipped back to my home in clarksville TN. And was informed by the delivery driver that the parts were in the back of my car. So now I have a car that was taken apart but not fixed with a bunch of parts in the cargo area and about $2000 in debt for a rental car and shipping the car back too clarksville. Since I have had this problem I have found out that the transmission and cooling systems have been malfunctioning since 2004.

The contact owns a 2006 Nissan Pathfinder. While the vehicle was parked, the contact attempted to start the vehicle but it was making a noise. The contact had to fill the fuel tank to get the vehicle started. The vehicle was towed to an authorized dealer where the cotnact was informed that the intelligent power distribution module needed to be replaced. The vehicle was being repaired. The contact referenced recall 10v517000 (engine and engine cooling) but was informed by the manufacturer that the vehicle was not included. The current and failure mileages were 84,880.

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 40 mph, the contact attempted to accelerate further and noticed that the vehicle did not have as much power as it usually did. The contact heard a whining noise from the engine. The vehicle was taken to an authorized dealer where the contact was informed that the timing chain needed to be replaced. The vehicle was repaired. The contact stated that the fuel gauge stopped operating. The contact called the manufacturer who stated that the vehicle was not included in recall 10v075000 (fuel system, gasoline: storage: auxillary tank). The vehicle was repaired by an authorized dealer. A few months later, while driving approximately 45 mph, the vehicle stalled. The vehicle did not restart so it was towed to an authorized dealer where it was repaired. The contact called the manufacturer who stated that the vehicle was not included in recall 10v517000 (engine and engine cooling). The failure mileage was approximately 72,000 and the current mileage was approximately 84,000.

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.

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.

Truck began to shudder as if driving on rumble strips, then overheated on major highway. The transmission fluid and cooling fluid mixed due to defect. Radiator had to be replaced and truck completely flushed several times. Good chance that transmission was damaged and will have to be replaced, also. Total cost of repair was $1500.

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.

2006 Nissan Pathfinder - in August the fuel gauge stops working I have to replace the fuel pump. In December the radiator coolant and transmission fluid mix and I have to replace radiator and flush transmission fluid. In January the ipmd module goes out, car goes completely dead on freeway and almost causes an accident. In February ses light goes on again this time catalytic converter goes bad. February 24 coolant and transmission fluid mixing again taking to shop tomorrow. Please look into the issues, if you search the internet you will discover this is not an isolated incident. Please help. I'm sure I will be posting again next month.

The transmission cooler is located in the radiator and cracked. This results in the mixture of anti-freeze and transmission fluid. So the ending result is anti-freeze in the transmission and transmission fluid in the radiator. The transmission starts slipping then fails. . . . . . .

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.

2006 Nissan Pathfinder was taken today for a routine yearly inspection. Only issue I have had with it is the heater periodically doesn't work correctly. At the Nissan dealer, I have been told the vehicle is in need of an entire transmission and radiator replacement due to the fact that a "cooling line is broken and all antifreeze mixed in with the transmission fluid". Estimated cost is $7000. In addition, the catalytic converter needs replaced. The repairman indicated "many" Pathfinders have this problem. After searching on-line, there are multiple people angry that their Pathfinders are having the exact same issue, yet Nissan is still not assuming any responsibility for any of this. I also filed a complaint with Nissan customer service. This is quite disconcerting, as the vehicle is only 4 years old, and I am now being told I shouldn't even be driving it. They are offering to help only by giving us a great deal on a trade. However, I no longer trust Nissan, and would not trade for another Nissan. I am asking Nissan for some explanation, and some financial assistance on this issue, but I have not had a reply. The dealer only offers a "great" trade-in value - the manufacturer hasn't replied yet (assuming they will reply at all". Thank you for your time on this matter and anything you can do to assist.
