Automatic Transmission Cooler problems of the 2008 Nissan Pathfinder

Transmission failure due to antifreeze coolant cross connection into transmission fluid cooling system. Cost to repair $4,700. 00. 2008 Nissan Pathfinder se 4. 0 4wd. Transmission failed while traveling a 4 lane divided state and federal highway moving straight. 03/08/2020.

I am having issues with the car slipping gears. I took it to a reputable transmission repair shop where I was informed there is a "crack" in the cooling part of my radiator and my radiator and transmission and both need replaced. Also that the radiator fluid and the transmission fluid are mixed together.

I bought the car from a used car dealership with 109,000 miles on it. Not even a month after buying it, the intercooler line cracked causing the transmission fluid and coolant to mix. This completely destroyed my radiator, which I had to replace, along with flushing the entire cooling system. It also caused my transmission to fail. To repair my car will cost me about $5,000. I went to Nissan about this and was told they could not help me because the car has over 100,000 miles on it. I was able to temporarily fix it, but now my transmission is completely junk and I can't afford to fix it or give it back to the bank. All of these issues occurred while I was driving the vehicle.

2008 Nissan Pathfinder. Transmission failed due to radiator failure which caused contamination of the cooling and transmission fluids. Engine overheated due to contamination. Entire cooling system had to be flushed several times after repairs. Repairs were over $4000. Nissan refused to address issue because of pending class action suit. I wish to be added to class action process to recoup expenses.

Engine coolant leaked into transmission destroying transmission and radiator requiring replacement of transmission and cooling system. Vehicle odometer is at 115,000. Estimated repair is $3000-4800+.

On my 2008 Nissan Pathfinder, which is only 8 years old, I have repaired my transmission due to an atf contamination via the cooling system around 95,000 miles. I purchased the vehicle at 90,000 miles used. This affected my speed control and all related systems. The radiator was replaced also due to the contamination. This has affected my cooling and heating system and all related systems. This cost my extended warranty company around $2,900+ (glad I was Smart enough to purchase this warranty), however it cost me my deductible of $200. 00. On February 12, 2016 I dropped my Nissan off for a follow-up repair to replace the entire timing chain assembly after going in for a simple alignment earlier (which was a waste of money because you have to purchase a camper kit in order for your alignment to be 100%, $249. 00 out-of-pocket). This caused me to have to buy a brand new set of tires out-of-pocket which came with a free alignment as a special, otherwise I would've re-payed for another alignment. Headquarters Nissan of columbus,GA never informed me of the timing chain issues with these suvs! this resulted in performance issues. Again my extended warranty will pay around $1,800 to Nissan for the repairs and me a $200. 00 deductible. I have run out of gas in the middle of traffic on the highway in atlanta,GA during rush hour before because my gas gauge or indicator or something doesn't read or is inaccurate. I also hear noise from the tires or something when I roll over speed bumps, accelerate or bank left or right with bad, hard steering. The cooling and heating system has not blown air at times and sometimes I have to depress the gas petal while idling to heat up air that has gone cold. When the a/c does this I turn off the a/c and let the windows down, pressing the gas petal does not work. Nissan says they can't find a problem with this system when diagnosing vehicle?!.

Transmission cooling system runs through the radiator. Faulty design/construction lead to failure, resulting in cooling fluids in the transmission, and transmission fluid in the radiator. Occurred at 110k miles but Nissan will not acknowledge & repairs are $5770. Began with vehicle not shifting properly and then not getting out of first gear. Turned around & drove the 1/2 mile back home to discover viscus emulsion in radiator reservoir. Investigated & discovered this is a common problem on Nissan Pathfinders.

Catastrophic cooling/transmission failure. Traveling east on a heavily traveled single lane highway with no breakdown lane. Sudden noise from the engine compartment, sounding like liquids being expelled. Check engine light comes on. Engine temperature gauge pegs to high. Limped along the highway until I could reach a safe point to pull the overheating vehicle off road. Arranged for a tow and had the vehicle inspected. The inspection revealed failure of the radiator. After further inspection and with some research, it was discovered that Nissan has a known design flaw that contributes to the eventual failure, in a catastrophic event, of the cooling and transmission components. My vehicle was mixing engine coolant and transmission fluid together. The sudden failure of the radiator, expelled engine cooling and transmission fluid in a sudden and rapid event. This is a known and documented event that Nissan is fully aware of. A sudden failure of these components poses a safety risk for the owner, occupant, public and environment.

Radiator fluid leaked into transmission due to poor design of the cooling system for the transmission. This issue cost $4200 to repair the transmission.
