It was November 2011, I was driving my Nissan 2007 at that time I was 9 months pregnant. My daughter who was 5 years old was with me. I was entering the freeway when my car started to shake, make noises and it started to slowdown on its own. I presses the speeding pedal but it kept loosing power. My daughter was crying because she was scare. I was crying too I did not know what to do I was in a dangerous situation because it happen when traffic was at its pick. I could not stop because cars where behind me and I could not speed because my car was loosing power and it smell like something was burning. I manage to get off the freeway with the emergency lights and stop the car at the moment the car die(no power). A tow truck had to take as home. Nissan would not fix the problem because of the miles/warranty whichever comes first rule that they have. They would fixed for a lot of money anyway I took it to a shop an I was told it was the radiator which damage the transmission. I had it repair and a few days latter all the emergency lights on the car turn on and went crazy and the car stop at ones this time it was the gas tank. It scare me so much that I call my husband and told him, "this car is going to kill me and my children" Nissan Pathfinder is dangerous and something must be done or someone is going to get kill. It is a safety issue please help us. Do something we need help Pathfinders are dangerous Nissan won't fix this factory problem with out getting pay. Please a recall needs to get done. I beg you do something this is the usa or not" I know at list 3 more people that had the same problems with this cars and all the mechanics agree that it is a factory problem. I will never buy a Nissan it is a lemon! first radiator linkage then liquid in transmission then replace transmission than it will be the gas tank what is next"

While driving on the highway, I felt my transmission seem to shift very roughly into overdrive, and usually occurred between 40 and 50 mph. Over the course of about a year, it continued the behavior off and on, until it began to do it daily and I took it to the shop. It was diagnosed as having had antifreeze leak into the transmission due to the oil cooler lines cracking, a common problem with Nissan Pathfinders, and other Nissan vehicles of my model year. There was metal in the transmission pan which signifies that a rebuild is inevitable, all due to the mixing of antifreeze in the transmission. The radiator must also be replaced due to the mixing of transmission fluid, as the mechanics found the "milky" substance, typically associated with the mixing of water and transmission fluid in the radiator. So far, I have been quoted approximately 6,300 dollars for a repair job on this vehicle.

2007 Nissan Pathfinder radiator defect causing leak of coolant into transmission fluid and resulting in transmission/radiator complete damage, undetected by dealer service for 30,000 miles. Problem detected with opening of investigation. Nissan requires co-pay of $2,500 even though complaints occurred previous to 80K miles and when problem detected, was 414 miles over requiring a significant amount of money for a known defect.

My wife was driving my 8th grade son and his basketball team to middle school game. She was on the freeway going 65 mph, when she felt the car jerk and then start to lose speed, the engine was still running but the car had slipped out of gear. She had no power and luckily she had room to coast to the shoulder. We took the car to the dealer the next day they diagnosed the problem as transmission failure due to radiator fluid in the transmission. We replaced the radiator and coolant lines and flushed the transmission, and it ran fine for a few months. But the check engine light came back on last month, we took it in and now they tell us that we have to replace the transmission. Please investigate this issue with the Nissan Pathfinder, frontier and xterra. It seems to be more and more of a common issue with Nissan owners and Nissan is not doing anything to repair this very serious and costly problem. I just got an estimate on Tuesday (9/4/12) for $9459 worth of repairs to the transmission and the radiator. I bought the car new from Nissan, and it now has 110,502 miles.

Wife first noticed a vibration on her way home from school with our daughters. Became progressively worse over time. I had tires, bearings, etc checked. No problems found with any of those. Looked online and discovered that a lot of Pathfinder owners were having transmission problems. Checked coolant and found that it had in fact mixed with transmission fluid. I switched the lines from the transmission to trans cooler and radiator to prevent further contamination, and flushed radiator/replaced coolant. Also had transmission flushed/fluid changed. The vibration is still present, as I don't have $5000 + for a new transmission/radiator.

I have maintained my car. In June, my Nissan dealership charged me $1500 after I reported a jolt in the transmission. I brought it back 08/10/2012 and they said the transmission needed replaced. I took it to another shop and they said the radiator fluid had leaked into the transmission and ruined the transmission presenting a financial burden and a huge safety issue. Updated 09/13/12

I drove 2hrs away to pick up my niece from college. The vehicle was fine on the freeway, but as soon as we exited, it started to sputter. We were very close to campus so we pulled in and made it through a couple more stop signs before we pulled into a stall and parked. It would not start after that. I had to tow it back home and to the dealer ship where I was told that a problem in the radiator caused fluids to mix which shot my engine. Now Nissan wants to charge me $7650 for a radiator and transmission. That's ridicules considering Nissan knew these vehicle had faulty radiators in them. This could have been very dangerous if this occurred on the freeway!

Car would not engage in reverse. The problem was diagnosed as my transmission failing due to design flaw that allowed radiator cooling fluid to leak into the transmission. I had to replace the transmission at a cost or $3,400. The car warranty had run out and I was not reimbursed by Nissan. Nissan has not recognized that they have a design flaw issue that is costing their car owners thousands of dollars in repairs as well as ruining their reputation.

If you are not already aware, there have been many problems concerning this vehicle, which are almost all similar to each other. Personally I have been experiencing transmission problems which range from: Rough engine vibration at 40mph, and 60mph, thermometer spikes when accelerator is engaged at 2500+ RPM, violent jerking of car, loud engine fan, and most importantly loss of forward acceleration when actively pressing on gas pedal. I brought this to a Nissan dealer to have this diagnosed and they have confirmed that my initial worries were correct. A defect during manufacturing of this vehicle has caused radiator coolant to leak into the transmission or vice-versa causing the deterioration of both systems. This in turn correlates to engine overheating and many other problems while driving this vehicle also the housing of the timing chain is non-existent. The vehicle diagnosis and price quote for repairs nears the $10,000 mark.a price which is almost half of what I purchased the vehicle for. As of yesterday 3/17/12 my vehicle has lost acceleration power.

This experience has been absolutely terrible. I am a mother and drive to all of the activities everyday which adds immense stress on me everyday knowing that any second my car will break down leaving us stranded. I bought my Pathfinder used from the Nissan dealership and have barely owned it for 2 years. I took it into the dealership after it was running at 40mph and would not let me accelerate and making crazy grinding noises as though I were riding on the road shoulder. The dealership informed me that it wasn't a problem with my transmission but my radiator leaking coolant into the transmission which as a result ruined the transmission. Having done research on the issue I have read that it is a common issue with these models and that Nissan corporate is well aware of and refuse to do anything about it. This is a great big safety issue imposed on my family and I am terrified to even drive. I am upside down on my vehicle and cannot trade it in on a new vehicle and am left with my hands tied. I am joining the other millions out there filing a class action suit against Nissan in the hopes of resolving this issue.

The check engine light stays on the car. Also, the fuel delivery system has become a significant hazard in the car. The Pathfinder's gasoline gauge indicates that it is half full, but suddenly the yellow light comes on to indicate the car is empty. This is a significant hazard while on the highway and there are times where a gas station may not be easily accessible.

I haven't finished paying off my car and already the transmission of my Nissan Pathfinder 2007 XL is failing. The radiator spilled the cooling liquid into the transmission, which then proceeded to cause serious problems to the transmission. The guaranty expired after 100 000 miles, even though prior to that the mileage the guaranty still applied. Now, in order to fix the transmission, or replace it for a new one, will cost me over $5000usd. I'd like to unite to the existing complaints/lawsuit against Nissan on the matter of the faults found in the 2007 Nissan Pathfinder, as I feel that is unfair that the company with the knowledge of fault in its product has not warned the public and has proceeded to sell the product to the public, leaving us with a faulty machine that in the end is more expensive, and not a satisfactory product. I am hopeful that the company will response to all of our complaints, stepping forward and taking responsibility for the inconvenience they have caused, and hopefully taking ownership of the expenses that due to their lack of responsibility, have been incurred on to us, the consumers.
