Nissan Pathfinder Problem Report

Nissan Pathfinder Radiator fails and dumps coolant into transmission fluid destroying the transmission

(34 reports)
This is happening to thousands of mostly 05 and 06 pathfinders. Nissan denies the problem as it usually occurs after the 80,000 mile warranty period. If your transmission still has bright red transmission fluid get it to a garage quick and request that they add a transmission cooler and eliminate the cooling loop thru the radiator. If your transmission fluid is pink then just go ahead and have the transmission rebuilt and a cooler installed. Nissan will charge you up to 6,000 for this job so go to your local transmission shop instead. Google pathfinder problems and join the list of people ripped off by Nissan, never buy another nissan product and join the class action suit against Nissan. They installed a defective radiator in these cars and refuse to take responsibility for it. -
In 2/2007 after driving my 2007 Pathfinder SE Off Road for only 3 miles, it started to slip while shifting and making loud clunking sounds. I pulled off to the side of the road and saw an odd colored liquid leaking from the coolant overflow tank. I left the car and called for a ride home. A few hours later, I went back to the car with some coolant and water, expecting that there was some sort of coolant leak. Upon opening the radiator cap and the overflow tank, I found a sludge like pudding consistency liquid. The car was towed to the local repair shop and I was told that there was a leak and the coolant system and the transmission fluid had combined. They said they see this with many Nissan trucks. I had the radiator replaced and the the transmission flushed several times until there were no remains of the sludge in the transmission. ----Cost $1,300.00 I drove the car for about a month without a problem at all, until while driving up my street the car lost all acceleration and had no forward or reverse gears. This time it went to a transmission shop. A complete rebuild was required. And, it was also suggested that we add an external transmission cooler. However, I was told the transmission computer was still ok. ----Cost $3,350.00 After receiving the car back, I drove it approx 75 miles and experienced the same loss of acceleration and no forward or reverse. Back the the transmission shop it goes. The transmission shop takes the entire transmission apart to learn the the transmission computer is bad now, which is located in the transmission. ----Cost $1,200.00 Nissan is aware of the problem - It's a design flaw. The same design is used in other trucks they make. I'm aware of the "Class action law suit" however, it doesn't help anyone who has a truck with over 100,000 miles, and considering that is when the problem develops, I find Nissan's fix ridiculous. I have now spent $5,850 to fix a problem that Nissan should have issued a full recall for. I will never ever buy another Nissan again. I've made it a point to let everyone I know to never buy a Nissan product. It's truly amazing how my local Nissan dealer wanted no part of helping me. -
Coolant mixing into transmission. Dealer asking 6,000 to repair. What a rip OFF!!! I want buy another nissan. -
Had to put 3400 dollars in for a rebuilt transmission last year at 88,000 and just learned my radiator is spilling crap into this new one. Just passed my 100,00 mile mark. Single mother that has just recently been laid off. -
Break in the radiator dumped coolant into the transmission and ruined it. Required replacement of both radiator and transmission. Also had timing belt on its way out when I got the car to the shop and that also required replacement. Also had a fuel gauge that wasn't working and required replacement for that. Total cost >$4800.00. Radiator/Transmission problem was a few months out of the time for full replacement and it cost me a healthy "deductible" to have it fixed - plus all the other repairs. At the time, there was less than 64000 miles on the car. -
I am still paying for a car that has been sitting in the driveway for over a year. -
Had to replace transmission -
Car overheated. That's how I found cross contamination. Waiting to here from nissan for assistance -
Had Radiator rupture and mix coolant into transmission, destroying both of course. Noticed the issue when I drove at around 50-80 mph. Experienced hard grinding like vibrations and hesitation when this happened. Drove this way for a weeks then took into a Nissan dealer. Was told they couldn't find the issue. A mechanic rode with me to see if he could experience what I did, but would check again when I rescheduled. Meanwhile during that ride along I mentioned what I suspected it to be because I did search on the internet about the symptoms. This exact same thing is what I read people were having. Rescheduled the appointment Tuesday of this week and within an hour and half they called to inform me what I told them it could be. Radiator ruptured and leaked into transmission destroying both. $7,600 repair but luckily it was covered 100% because I purchased the 5-yr warranty 2 years ago. -
I have had to have mine rebuilt. -
Radiator dumps coolants into transmission without any warning .. Transmission malfunctions... Now I'm in three thousand d but to replace transmission and radiotor -
I just had this experience with my 2007 Nissan Pathfinder -
Was just told that my radiator and transmission need to be replaced on my 2005 Nissan Pathfinder. Did not know so many owners had the same issue. I feel so betrayed by Nissan. Over $6000 to fix now what??? -
Driving along and felt what some would describe as riding over milled rumble strips on highway or raised rumble strips near school zone. Took it to my mechanic and he eventually narrowed it down to a vibration in the transmission. Only to find a milky, yellow/brownish liquid in my transmission. NOT GOOD! Already flushed 20 quarts through, color still the same! dtd 24 March 2015 -
Bad radiator, mixed coolant and transmission fluid apparently. Sudden stuttering while going down the interstate, felt like I was running over bumps. Began to notice temp gauge going up, realized I hadn't had heat in about a week. I'd previously thought it was just so cold and my distance was so short of a drive that it hadn't had time to heat up before I arrived at work. Currently replacing radiator, they've flushed transmission fluid several times and think I may need a new jug as well. Also have been told I need another catalytic converter replaced. 2nd one in 2 years. -
Same problem, different day. Nissan dealership quoted me $7K to replace the transmission, radiator and intercooler. Took it to a local transmission shop and had the entire job done for $4500 at 87K miles. Fuel level sensor does not work and after transmission/radiator fiasco, temperature guage is pegged at H. Received a recall notice from Nissan for EMC (really) and took it to local Nissan dealership. I was told the EMC replacement would probably fix my fuel level sensor problem - not. But they were happy to call me and tell me that two of my 4 catalytic converters were non-functioning and they could ewasily replace them that day for about $3K. Fortunately, I have never been able to get that error code duplicated and I have taken the car to a dealership in Atlanta, two local exhaust specialists and my regular mechanic. It seems that Nissan USA not only built a crappy car, but they teach thier dealerships how to crap on you also. Will never buy another NIssan - EVER! -
Radiator fails and dumps coolant into transmission fluid destroying the transmission -
Transmission problem due to water in fluid damages computer and belt. -
My truck started making this funny noises when ever I drove over 60 mph.then I saw stuff on the internet about the creamy substance in the radiator and when I checked my radiator,I saw the same milky like substance. -
Just had my transmission rebuilt due to deadly code P0537. Had coolant fluid mix in transmission. Transmission shop added separate cooler for transmission. Mount in front of radiator and rebuilt ( vale assembly had to be replace) transmission. Cost little over $3500 dollars to fix This is a shame on Nissan they should had did a recall to change out transmission fluid that cause this problem. Nissan should be fully responsible for this matter. My transmission tech stated they have Nissan trucks that customers frustrated that they just abandon their trucks at their shop. Lots of Nissan owners have this problem not knowing that this is a dealer problem. I see Nissan was sue in 2010 for this issue and Nissan loss this case. I call several dealers on that law suit and that stated they know nothing of that and they wanted to charge me 150 to check and to fix estimate 5 to 7 thousand. That's why I took it to transmission shop. I will never buy another Nissan again. Never no kind. -
