Defective radiator from Nissan, dropped fluid into the transmission. As a result, both the transmission and radiator had to be replaced. If the radiator was defected the transmission would still be in tact. This happened just reaching the 100,000 mile mark.

The transmission would not shift into overdrive, so I took the vehicle to aamco. The transmission was contaminated with coolant from the radiator, requiring a complete overhaul including the transmission computer. Estimated cost of damages is $4600! my vehicle is in excess of the extended warranty, however this is a design flaw that should be corrected by Nissan.

The radiator was cracked where the transmission fluid is and it mixed with the antifreeze which caused both the radiator and the transmission to have to be replaced. The engine was on and vehicle was stationary when we noticed the temperature increased greatly and rapidly until it maxed out. The vehicle was leaking a mix of antifreeze and transmission fluid. We replaced the radiator but the damage was done already to the transmission. The vehicle was in motion when the transmission failed.

I was driving my newly purchased used 2006 Pathfinder and noticed that I could not get up to speed until I got up to 45 or 50 mph noticed I had several error codes ended up that one was the transmission valve assy. Took it to transmission shop which tested the fluid and found that there was radiator coolant mixed with the transmission fluid. The car was great except for this issue. Now it barely drives only in 4th gear and I am told if I keep driving it that way it will burn it up. I need to replace both the valve assy and the transmission and radiator to solve the problem at a cost of 5K. I do not have the money. This is really unacceptable.

The technician performed an oil change on the transmission and the transmission failed eight days later. The vehicle was towed to the alhambra Nissan dealer where it was diagnosed that the transmission and the radiator failed and needed to be replaced. The vehicle was not serviced due to the repair fees. The manufacturer was made aware of the failure and informed the contact that the vehicle was old in age and out of warranty. The manufacturer did not offer further assistance. The VIN was unknown. The approximate failure mileage was 123,000.

While driving on the highway, penultimate week. I observed loud engine noise, vigorous shaking and jerking and a reluctance in acceleration when I applied gas pedal​. I was a little bewildered as I have been very punctilious with the regular maintenance of my car. I gently pulled into a parking lot to avert any danger on the freeway. Upon exiting the car, I perceived a pungent burning smell. At this point, I knew it would be unsafe and pernicious to drive the car home. I immediately called for roadside assistance through my insurance company and had the car taken to my mechanic. He called back the following day with the most disheartening news. For some uncanny reason, fluid from the radiator was leaking into and contaminating the transmission. He vehemently pointed out that he had seen quite a few of the same ominous problems brought to his shop, involving mostly 2006 Nissan Pathfinders. I was given a quote of about $4500-$7000 to fix this problem. I purchased the vehicle from a used car dealer with approximately 117,000 miles. I'm currently financing the car and because of my student loan and exorbitant fees, I still owe a lot on it. Honestly, I cannot​ afford the repairs at this juncture. It is very rapacious and immoral of Nissan to abdicate their responsibility and pass on the financial burden to innocent consumers​. these cars had factory defects and design flaws that Nissan was aware of but chose to ignore. I enjoin anyone having similar problems and indeed conscientious members of the public to vociferously condemn Nissan's action and force a recall. This is corporate greed at its worst !!

Total transmission failure on I95 in Connecticut,10pm at night, at 55mph, with family in car. Coolant leaked into the transmission causing a total transmission failure. Nissan knows about this problem and did not contact vehicle owners to warn of the problem or offer suggested repair. Replacing the radiator would have been a $300 fix. Instead Nissan offered no warning and the extremely dangerous transmission failure on an interstate at night happened. Total cost to repair was $4381, plus a week car rental.

I paid off my Pathfinder last year. Just about 2 months ago after leaving a friends house the truck started turning on all the dash board lights, I didn't know what to expect. I drove it very slowly home not even a mile away, I turned it off and next day..my surprise it didn't turn on to take to the mechanic. I called the tow truck to take it in to Nissan dealer and they found that the radiator fluid mixed with transmission oil and messed up the module too. They where originally charging me 7200 dollars to fix. I brought it back home and after when I was able to pay with credit I took it in to fix. They urged me to fix all at once because of a manufacturer defect on any of the above..most likely they said it could happen again.

The transmission and radiator fluid mixing and causing transmission to fail. I see that you have had many complaints about this issue and you choose not to help the consumers. This is a very dangerous issue and a very expensive repair. This is obviously a continuing problem and an extended warranty isn't fair to the consumer because this is a faulty issue with this model transmission/radiator.

- Pensacola, FL, USA
