I had noticed fluid leaking from under the front /right portion of my vehicle after I parked. I opened the hood and the reserve cap to the radiator had come loose. After letting my vehicle cool, I inspected both the reserve tank and radiator and noticed the fluid was now a milky/frothy substance. After some detective work, I learned that this is a common issue with Pathfinders from 2005- through 2010 that Nissan has ignored to fix. The transmission fluid cooler in the radiator assembly "fails" causing contamination to the internal transmission components ,and damage to the internal transmission computer. There are no warning signs up to or just prior to the failures. After contacting Nissan and receiving a denial to fix our truck under a warranty, I am stuck with a vehicle with several "thousands of dollars" in repairs all due to Nissan ignoring a known defect and not issuing a recall on all vehicles in the "known" year bracket with these issues. I'm sure nothing will be done regarding this issue due to there not being a major loss of lives involved, I. E. Takata airbags,but I find it is my duty to add my name to an already hefty list of other Nissan Pathfinder owners that have experienced this same problem.

Radiator coolant leaking into transmission, causing transmission failure. Dealership has informed me because I am over 100,000 miles there is no coverage and will cost me upto 8,000. My current mileage at diagnostic was 104,000 miles. My Pathfinder is in great shape and has a lot of driving left in it. I feel let down by Nissan that they have known about this defect and will not stand by the fault to keep customer loyalty and satisfaction. I do not trust Nissan and never will again, they have proven to me they do not care about their customers and do not stand behind their product. I am in a position as a single mother with 3 kids that I cannot afford 8,000 dollars to fix this known problem. I could not believe that they were prepared to do nothing. . . . . . .

The contact owns a 2006 Nissan Pathfinder. When the vehicle was taken to the alhambra Nissan dealer in alhambra, CA for a routine oil change, the contact was also advised to have a transmission oil change. 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.

We bought a 2008 Nissan Pathfinder, with 97,000 miles. Zero issues at the time of purchase. At about 123,000 miles we noticed the transmission began to stuffer. Upon further investigation we discovered that the transmission fluid and coolant fluid have mixed together. The transmission will need to be replaced. We are currently financing this vehicle, making monthly payments, and now among millions of other Nissan consumers are in a horrible spot. Nissan should have issued a recall for cracked radiators. I work 12 hour swing shifts, live in a small town, and have 4 children. Nissan needs to make this issue right with consumers due to the shear volume of defective vehicles and the immense cost and unfortunate position it's putting hard working american in.

Failure Date: 02/11/2017

Vehicle shutters when trying to change gears. This occurs when driving at high and low speeds (it has an automatic transmission). If the vehicle is cold and I put it in drive, the transmission will not engage. When idling, the car blows cold air in the front, even if its set on the warmest temperature. The car consistently blows cold air in the back, whether its idling or being driven. After having my car looked at, the problem was found to be caused by a cracked radiator that leaked coolant into the transmission. Not only causing damage to the transmission, but also to the heater hose which is beyond repair and needs replacement. After doing research, I have found that this has been a major issue for Nissans with a year of 2005 to 2010, and although they did not do a recall, they offered an extended warranty up to $80,000 and 100,000 with a customer CO-pay. But for most people that problem did not start occurring until after 100,000 miles. . . Like myself. There was a class action lawsuit on this which settled in October of 2012. I bought my car from a Nissan dealership in April of 2011. Why was I not made aware of this at the time of purchase?!.

At 80000 miles timing chain had to be replaced $2100. 00 repair that Nissan was aware of being a common defect . My extended warrantee company did not cover because they said it was a pre - existing problem. At 82000 miles radiator transmission cooler leaked antifreeze into transmission causing failure to both. Another problem that Nissan was aware of and would not pay for a repair for over $6000 because they had no recall.

Takata recall ?? the 2008 Nissan Pathfinder radiator and transmission failure and breakdown due to coolant leak into the transmission. Purchased pre-owned with nothing listed on car facts (carfax), or with any advisement to the issues with radiator coolant leaking into transmission. After a $1,017 bill from aamco for a diagnostic to find the issue, (in which they had to pull the tranny and inspect it was damaged due to fluid from radiator getting inside compromising transmission seals) I discovered, online, this ongoing well know problem. . Called Nissan north America and discovered my vehicle was covered under the 100k mileage (94955 actual) and good through 8-2017, from a previous filed complaint or class action, not sure which. However, apparently I only qualify for a CO/pay of $3,000 on a vehicle valued at tops, $7,500. Needless to say I would have never purchased this vehicle, had I known this was an issue. I have been in touch with my bank, the dealership I purchased it from, and Nissan north America and no one is willing to assist. I suppose I will contact my attorney at this point (lemon law, tort laws, something) because I cant' seem to find anyone understanding to me, the consumer, whom is not at fault on this deal for help. I am extremely unhappy that Nissan has allowed this to happen. They should at least put a carfax warning or something to notify potential buyers or owners of this problem. I understand that parts get worn and go bad, however, this in not something that I have neglected to fix, maintain, check, or anything. This is a bad part/design flaw in the coolant system and should in all rights be fixed at 100% by Nissan. Beware.

I was stranded in a parking lot because my car would not start. After having it towed to the dealership, I find out it is the "intermix" between the radiator and the transmission. I never received any information about this from Nissan, but now understand it was a known and frequent failure - by design. Essentially, after 90,000 mile, the car is worthless because of this issue. After paying $5,000 for the repair, I drove off the lot only to have my fuel pump fail. Literally, I drove off the lot and the engine began misfiring. Unbelievable.

I took my 2005 Nissan Pathfinder into the shop because it was having trouble shifting gears at highway speeds. I later learned the bad news that the hoses in the radiator have failed causing coolant to cross contaminate and mix with transmission fluid producing a toxic sludge that ruins the radiator as well as the transmission. I was told that $4,000 later I would need a new radiator, new transmission and new hoses. The service technician also told me that this problem is very common in 05-06 Pathfinders. After going home a quick google search revealed that tens of thousands of cars have actually dealth with this problem and there was a lawsuit brought against Nissan for these problems. Unfortunately I never knew of such a lawsuit and now that I have the very problem it's too late to do anything about it. That type of service by companies for selling faulty products to their consumers is really too sad.
