problem #316

  • 92,800 miles


I took my Pathfinder in to the local Nissan dealer for a check up--chugging at 35mph, check engine light sporadically goes on and off, gas gauge stopped functioning. Nissan ran the diagnostics and told me the check engine light is because I need to pay $500 to replace the fuel sensor. I believe this is a part that was previously recalled. I don't know if Nissan considers the fix once and done but vehicles driven in salt and sand winter conditions will need extra attention. The transmission trouble is something Nissan knows about but refuses to recall. I was told I needed to replace the radiator and transmission--over $5000. If Nissan knows about these problems, why must I, a now unhappy owner, pay for these repairs?

My cars radiator cracked and leaked into the transmission. The mix of coolant and transmission fluid damaged the transmission and quite possibly damaged my engine. Nissan knows about the radiator because they extended the warranty on it. The repairs for this incident are high the Nissan dealer I took it to quoted me $4,591.43 to replace the transmission and the radiator and that is with the warranty they claim they have on it. The dealer also told me any other damage caused by this faulty radiator would not be covered and I would have to pay for the repairs to any other components as well they told they me might be an additional $2,000 so nearly $7,000. I had know choice but sell the car off as scrap as the repairs would cost more than the car itself. A failure of all these parts at once is a safety hazard to everyone.

I am in the middle of a road trip with my children and suddenly my Pathfinder would not accelerate going uphill. I thankfully made it up the hill and onto a highway on ramp. The grace of god is all that kept me from being struck by a tractor trailer taking the same exit. The Pathfinder shuddered and I pulled into the shoulder (a blessing that there was just enough space for one) and it turned off right there. Not even 85,000 miles on an '06 Pathfinder and I had to have the steering column replaced after something broke it in it 2 yrs ago, now this. I had it towed to the closest Nissan dealer, 35 miles from where it stopped and hundreds of miles from home. The dealer told me it was the known issue with the cheap plastic radiators and transmission. I am now in a rental car, looking online for a hotel (I was planning on driving up to Canada and an now stuck in Ohio), and have to pay $3,000 to get this fixed because of the age of the car. Nevermind that it is a known issue!!

The transmission of my Pathfinder went bad because of defective radiator. It mixed transmission oil and antifreeze in the transmission. It will cost me 6K+ to repair. I read a lot of people had this problem and I want Nissan to fix it.

I backed out of my driveway onto the main road and went to put the vehicle into drive and it would not go into drive. When I got it to the repair shop they said that the radiator had leaked into the transmission and caused it to ruin the transmission.

Just after exiting freeway, vehicle's automatic transmission failed to engage in any forward gears. This caused forward movement to reduce to extremely slow motion. If this occurred while on the freeway, and if a driver panicked, not immediately moving off to the side, it could have caused an accident with potentially serious consequences. This problem is widely known and has been dealt with to a limited extent. Don't see a place on this complaint form to indicate what the problem is. Transmission was contaminated with coolant due to lower trans line in radiator's lower tank being ruptured. Radiator was also cross contaminated with transmission fluid. This common problem in certain model 2005 - 2007 Nissan's is not currently a recall (it should be), and the limited extended warranty in the Nissan settlement offers no reimbursement for vehicles having this problem with over 100,000 miles, as is the case with most of us. I hope you are aware of the several thousand people who have had this potentially dangerous problem over the years, and the thousands more who will continue to have this same problem in the years to come.

The contact owns a 2006 Nissan Pathfinder. While driving at 55 mph, the contact noticed vibrations underneath the vehicle. The vehicle was taken to an independent mechanic who diagnosed that the transmission and the radiator needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 114,000. The VIN was unavailable.

The transmission fluid and the radiator fluid are mixed up due to vehicle design issues. Nissan is conveniently getting out of the complaint by putting in stuff that there is no warranty on the vehicle.

I purchased my 2006 Nissan Pathfinder in 2013 with 109K miles on it. I loved it for 1yr and a half. 2 months ago it started shifting rough, I took it to a local place to be looked at. I was told that Nissan Pathfinders have a faulty radiator that leaks internally into the transmission causing complete transmission failure! would cost $3600 to fix. I called suntrup and was told by the service department that they had never heard of this before and to bring it in, which I did and $100 later they told me the same thing I already knew from the other place for free. They again said they had never heard of this happening before but they could fix it for $6800! I began searching (not too difficult since it is all over the internet!) I called around trying to find a more affordable transmission place and every single place I called knew about the Nissan faulty radiators!! this is a prevalent problem for the years 2005, 2006 and 2007 Pathfinder, xterra and and frontier! Nissan refuses to do a recall stating it isn't a safety issue but there was a class action suit closing in 2013 (year I bought my car) and would fix the transmissions up to 100K (I bought mine at 109K. The national transportation safety board is looking into this issue. I did contact suntrup and talked to the sales manager who said to come in and they would "try and help me". their solution is to roll the $4,000 I am upside down into a brand new car causing my payments to go up exponentially! (also as a single mom of 3 kids in car seats a car isn't helpful, neither is super high payments). You can not tell me that they didn't know about this Nissan transmission issue being a Nissan dealer! they didn't know about the class action suit, the year I bought the car"!"! perhaps there isn't anything that can be done in my case but I do not think it is ethical to continue selling these models and years!!

Purchased vehicle from car lot Feb. 28, 2015. Drove this vehicle 5 times and the coolant leaked. Flushed system notice there was stop leak in radiator. Now my transmission slips and truck shakes during acceleration. This was a previous issue before I bought the vehicle because the shaking occurred when driving home. I thought this was just the tires needing to be balanced, but after research I know that it was from the coolant previously leaking into the transmission, and now I am left to deal with it.

My transmission went out on a busy intersection due to this coolant leaking into my transmission. My children were in the back seat when my transmission failed. Glad we didn't end up in a reckless and that my children are safe. There is numerous reports of this happening to these Pathfinders how is this not a recall.

  • 121,600 miles
Leak in radiator causing cross contamination between radiator and transmission fluids. This is causing hesitation in power during operation of vehicle. Per the Nissan service provider we took it to, the cars needs a new transmission and radiator at the cost of $6000 or it will soon die. We believe this is a manufacturer 's defect and a known flaw- many other complaints are posted by other owners.

Fluid cross contamination from radiator to transmission causing hesitation during operation of vehicle. Per Nissan service department, unless transmission and radiator are replaced this is unfixble and car will soon die. Repairs estimate is 6,000 dollars.

Pathfinder 6-cyl

  • 117,000 miles
The transmission started to slip, which needed to be taken out of overdrive from time to time. After a few months the transmission gave out completely on the highway. It will rev up, but will not drive. Apparently they are famous for the gasket leaking engine coolant with the oil. They should have all been recalled.
