Pathfinder 6-cyl

  • 60,000 miles


Transmission is failing especially in reverse, it shakes and slips. I took my truck to a transmission expert who informed me that these trucks have this manufacture issue and my truck should be under warrantee by the dealer, I did my research and I am now aware of the radiator issue and the extended warrantee will cover vehicles under 80K miles my truck just reach 60K miles which is when these issues start according to the internet. I took my truck to the dealer for repairs. They told me that my radiator was fine and I do have a transmission problem but not related to the radiator and wanted to bill me for a service fee. I called the expert I had been talking to and he advised me that this was bs and to ask if they did a glyco test which they did not and ask how they knew it was not mixing. The service manager stated to me that it will look slushy and mine was simply black or dark. Now I am no expert but antifreeze is green and trans fluid is red. Even a child knows that if you mix red and green you will get blue or a dark color, which to me explain why it is dark. The dealer just does not want to fix my truck for the price that the manufacturer will pay them which is approximately 2K so they rather tell me that it is not covered and try to bill me for 5K+ taxes so they can make a profit of 3K of which the service manager probably will get a 1K commission. I don't know what check they did but whatever it was my truck now leak antifreeze which was not an issue before I took it to them.

Pathfinder 6-cyl

  • 95,319 miles
While driving approximately 60-65 mph on the highway during a family trip, the car began to shudder. The shudder returned several times over the next few hours, but we made it safely to our destination. Had to bring into the shop where I learned the defective radiator on 06' Pathfinder causes it to mix transmission fluid with coolant. This caused damage throughout the transmission resulting in a hefty bill ($4774). I learned there was a class action suite against Nissan for this problem, but it closed last year. Hoping to find information on perhaps another settlement.

My radiator is evidently cracked, leaking coolant into my transmission, causing failure to shift. My vehicle began losing power. At one point, I attempted to accelerate through an intersection from a stand-still as the traffic light turned green. I was nearly rear-ended by the vehicle behind me as my vehicle was not moving, like being stuck in neutral.

Transmission failure. I have service records from reputable mechanic shop that the transmission problem started at $77K miles. Nissan does not care. The court ordered settlement (class action suit) lets them off the hook after $80K miles. $2,500 copay to fix a problem caused by radiator leaking into transmission. Terrible customer service at dealership (why I never went to them for repairs). They try to charge for stuff under warranty (my fuel gauge issue a few years back). I thought Nissan na would help but I was wrong.

Pathfinder 6-cyl

  • 87,000 miles


Have a 2006 Nissan Pathfinder le and noticed the transmission was starting to make a rumble strip noise around 45 mph. Did some research and discovered that Nissan had a defective radiator which caused anti-freeze to leak into the transmission through coolant line. Knowing that the radiators were defective why wasn't Nissan ordered to recall them. It is a safety hazard if you are traveling on the highway and your transmission fails!!! I now have to pay $2500 to pay for a known defect to have radiator and transmission replace.

  • 87,000 miles
Pathfinder experienced complete transmission failure. Car stalled in the middle of an intersection and the engine started smoking and fluids spilled out from underneath. People behind us had to swerve around us to avoid hitting us. Some good samaritans helped my husband push the car to the side of the road. He could no longer drive the car. Earlier in the day the car was having trouble accelerating and would jerk. We managed to get off the freeway before it stalled completely. We had the car towed to mossy Nissan and we were told by the service advisor that the manufacturer radiator that came with the car was badly designed. The radiators crack causing cross contamination of the radiator and transmission fluid which then results in complete transmission failure, which is what happened to our car. He told us there was a class action lawsuit, actually, and the settlement terms were that if your car was under 80,000 miles Nissan would cover the cost of repairs. Our car had 87,000 miles and so we had to pay $2500. Over 90,000 miles and you have to pay $3000. Over 100,000 miles and you're out of luck. We were told the repair runs about $7,000 outside the warranty period. This should have been a recall issue, not an extended warranty issue, because it is unsafe to be driving on the road when your car stalls and the transmission fails. The car has since been repaired but I no longer feel safe in a Nissan. Nissan North America refuses to take responsibility for a design flaw and the extended warranty from the lawsuit benefited no one but Nissan. You couldn't have your radiator replaced under the warranty if it wasn't malfunctioning yet. Your car needed to break down before the warranty could kick in, and at that point you were already outside the 100% coverage window.

  • 125,000 miles


Same issue as all others, drive a 2006 Nissan Pathfinder and was happy until 125tsd miles never a big repair. Now I have the same issue faulty radiator kills silent the transmission. Did visit the dealer for every service even as the problem starts little by little. First a unpleasant shifting, dealer recommends a transmission flush before the official service interval, done. After we are still not happy as we can tell the transmission shifts different as we did know it from before. See the Nissan dealer again, they write the order with the customer complaint, "customer complains about transmission problems". written statement of the dealer, transmission checked no issues found. Some miles later, total fall out of the transmission special the tcu. Good customer will not see now dealer again but a lawyer.

Pathfinder 6-cyl

  • 100,000 miles
Nissan Pathfinder just got to 100,000 miles when started experiencing transmission issues, turns out there was a factory warranty that I was never informed of that would have covered the radiator/transmission issue. However because I was not having an issue until the extended warranty ended Nissan is refusing to cover the cost of repairs despite knowing about this engineering fault. It is extremely frustrating that a large company such as Nissan is able to send a vehicle out into the public with known engineering flaws and put a mileage limit on repairing the issue. It is something that will inevitably fail but it is only a matter of time so it might have occurred within the limit for some and outside the limit for others. It is my hope that you will expose this shady and unsafe practice that Nissan has going and help get people the repairs they deserve.

I noticed a shudder when the car was shifting, my mechanic test drove it and sent me to the transmission shop. The gentleman there told me that it was a transmission problem. He also said that this was a common problem with this year Pathfinder. He thought that since this was a common problem that Nissan had extended the warranty. I later found that the warranty had been extended but not enough to include my truck. Very disappointed in Nissan, I have owned 4 Pathfinders and several other cars made by Nissan. I thought they would take better care of loyal customers.

Vehicle transmission stopped shifting while driving in traffic. Sounded like vehicle couldn't switch gears any longer. This is serious problem and lucky it did not result in an accident. We have kept the vehicle on the proper maintenance schedule. With so many complaints this needs to be a recall.

Pathfinder 6-cyl

  • 140,000 miles
Noticed vehicle pulling off sluggish and wasn't shifting gears. When I made it home, I had it checked out and found transmission fluid mixing with the engine coolant. I started searching online for recall and found this is a common problem, but there isn't a recall to fix the issue. I also didn't know they extended the warranty to 80,000 miles to only have the radiator replaced. They to do something to fix the problem and make it right for their customers.

Pathfinder 6-cyl

  • 80,900 miles
Radiator developed a crack which leaked into transmission - both had to be replaced. We were told, due to a class action settlement in 2013, we were responsible for a deductible of $2,500 since our vehicle started problem after 80,000 and past March 1, 2014. Did not realize this problem until we took vehicle in, by that time mid April 2014 and at 81,990. This should be a recall.

Driving down the road, vehicle becomes sluggish. Notice that the temperature begins to rise rapidly. In afternoon work traffic and have difficulty negotiating traffic trying not to break down in the middle of a busy road/intersection at 5:20pm. Vehicle was take to a repair shop where I was informed that the radiator had ruptured, thus sending coolant into the transmission and transmission fluid into the engine. Current estimate is approx $3000.
