I was driving and suddenly the check engine light came on, I drove home and the next week I went to replace my brakes and ask the workshop to do a scan to let me know why the light is on, they did and 2 codes came up which the shop said they did not see before so they cleared the system and said if it comes on again to take it back so they can fully investigate. I went on 9/28 to another workshop they did a scan and the code p1772 came on after inspecting the mechanic showed me the radiator cap with some thick gooey stuff telling me the radiator is bad and the coolant is mixing with transmission fluid and vice versa. Before this the car would run and when I at a stop sign and try to move it would rev to 4-5 stalls and then move, they are also times of sudden jerk and acceleration. They have also been twice when I tried to reverse the vehicle would not move, I had to turn off the engine then restart before I could reverse. . Defective radiator cracks leading to coolant mixing with transmission fluid, now need to replace radiator and transmission.

While driving today the rpms went crazy and I almost wrecked . The car would spudder and then rev up. Also, at a stop light when trying to go the car seems to barely move and acts like it's going to die. Now we have transmission problems and have had to replace radiator,hoses, and all fluids in transmission and radiator.

I was driving down the highway with my kids when the vehicle started to overheat and when I pulled over the vehicle started to smoke and shut down. The vehicle was then towed to my house. I had a family mechanic look at the vehicle and was told the radiator cracked. I ordered a radiator and it was put it. Then found out that water had gotten into the transmission fluid. Went and bought the transmission fluid j specifically for Nissan and was going to flush the transmission fluid and add more it was then that the transmission started slipping and white smoke was coming out of the exhaust. Where I was told the head gasket is cracked. I am still making payments on this car and have no vehicle to drive to work or school.

Radiator cracked, leaked into transmission causing transmission failure.

Radiator has cracked and leaked into the transmission.

Tl-the contact owns a 2007 Nissan Pathfinder. The contact stated that while driving they pulled over the vehicle did not restart. The vehicle was towed to a Nissan dealer heritage Nissan 1500 veterans memorial hwy ne, rome, GA 30161. The dealer stated that a leakage in the coolant and radiator system leaked into the transmission causing the vehicle not to start. The contact had the vehicle towed to a an independent mechanic who made the repairs . The manufacturer was contacted and never called back. The failure mileage was 107,859. Tf.

The vehicle started vibrating very roughly and loudly during acceleration, then suddenly the transmission completely failed while my daughter was driving it on a very busy frontage road to the highway. She was able to steer it onto the shoulder before it stopped coasting; and several people stopped to help her push it into safety in a nearby parking lot. After having it towed to a repair shop, the mechanic informed us that the radiator fluid had leaked through cracks into the transmission fluid, causing irreversible damage to the transmission. Upon researching the problem, we discovered this was a known and acknowedged problem with 2005-2010 Nissan Pathfinders, but neither a recall nor a warning was ever issued. We are now beyond the warranty coverage in time and in mileage, so Nissan will not cover any of the expenses to repair.

In 2007, I purchased a new Nissan Pathfinder, unaware of any defects. In 2011, I began having problems with my truck not producing heat while it was idle. Nissan stated that the coolant looked dark and advised me that their was air in the line. Once again, I'm having trouble with the heat and now I'm being told the transmission and coolant fluids are intermixed, and that it would cost between $7 and 8 thousand dollars because I need to replace both the transmission and the radiator. When I took my truck to Nissan in 2011, and they knew the coolant was dark, I should have been made aware of the defect with the radiator assembly because my issues most likely had already started, and now, it's gotten worse. I was never advised of this problem until now.

I bought my 07 Pathfinder in July and the dealership had done repair on the radiator at their expense, and replaced the coolant and tranny fluids and stated there was no cross contamination. However, the vehicle stopped shifting properly and we couldn't tell if it was the tranny, abs, or 4wd getting caught. As of yesterday the tranny wouldn't change gears. Restarting the car helped. But since there was no recall there is no history of any other work. All maintenance was kept up with the same dealership for the majority of the vehicles life. After the vehicle has been at a stop, and moved to accelerate it wouldn't go into gear/drive then all of a sudden would ?catch? and would launch.

While driving the vehicle temperature gauge pegged out at the high side and there was a burning metal smell. I was told by two different mechanics that the radiator failed and leaked into the transmission. The vehicle is beyond the extended warranty that Nissan gave and they never contacted me to let me know that there even was an extended warranty.

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.

Enjoying our Pathfinder one afternoon and went to pass a car and it would not kick inot passing gear. When we stopped I could smell that it was hot, but could not find a leak. After letting it cool, I checked the coolant level and found that grey froth in the radiator. A quick check on the internet lead me to me worst fear. I am still in the process of flushing radiator and getting quotes. Local aamco guy said that transmission is doomed, and they see a lot of these. $4,000 - 4500 to rebuild.

"takata recall" out of the clear blue I was driving my 2007 Pathfinder and the airbag light came on, I took it to the dealership immediately that day and it passed per service manager louis castillo at baker jackson Nissan in houston texas, 2 days later the light came back on and once again I went to the dealer ship and was told that the sensors and other parts needed to be replaced the cost is $1500. I called Nissan corp and they are refusing to taking responsibility even though they stated all 2007 Pathfinders in other states would be given a 10 year warranty. My truck was also affected with the radiator flulid mixing with the transmission fluid, during the years of 2010-2012 I constantly took my truck to baker jackson Nissan and the service manager then larry just topped off my truck himself and never made a record of it. He kept assuring me that he was saving me money. My transmission failed but because of the mileage in 2012 Nissan was able to deny fixing my transmission via the class action lawsuit. I ended up spending $4800 for a new transmission. In 2010 Nissan convinced me to replace my train for $1600, I never knew it was a recall until today. Another caveat to this mess is that baker jackson changed their computer system and has no record of me replacing my train. I have a bank statement to prove it if necessary.
