1 Radiator problem

Failure Date: 06/05/2019

I was driving on an interstate at normal highway speed when the car shuddered as if going over rough pavement. The engine started racing, but the car gradually lost forward propulsion. I steered to the emergency lane and stopped. After a minute, the car regained just enough forward motion to get me to the next exit, across an intersection (where the light just happened to be green, thank goodness), and into the parking lot of a large grocery store before the vehicle lost all propulsion. We pushed the car the last few feet into a parking spot. It was towed to a Nissan dealership. I was told the next day that the transmission warmer had failed, allowing radiator coolant to leak into the transmission, which ruined the transmission. The repair would cost $6000. I cannot put another $6000 into a 13-year-old vehicle, even though I've only had it for five months, so now I've lost the money I put into it and will have to start over with another vehicle.

2 Radiator problem

Failure Date: 03/23/2019

Transmission is failing quickly. I had to replace my radiator a few months ago because it cracked. That event left my wife and children stranded on the interstate.

3 Radiator problem

Failure Date: 03/18/2019

Radiator failed causing leak of radiator fluid into transmission causing vehicle to be towed to auto shop. Vehicle was in motion on highway and then would all of the sudden no longer accelerate. Mechanics, (got 3 estimates) all said same thing; that this was a problem with these Pathfinders. My cost is about 6,500. I had just bought this vehicle for 8,500 about 3 weeks prior.

4 Radiator problem

Failure Date: 05/21/2018

My problem is with the radiator and transmission fluid contamination. . Some hoses inside the radiator that carries transmission fluid and coolant cracked and contaminated both the radiator and transmission. This problem has caused my vehicle to lock into 4 wheel drive and contaminated both my radiator and transmission this problem will need to be repaired before the vehicle can be driven. It will be a costly repair that should be covered by Nissan on a recall according to all the complaints I have read about.

5 Radiator problem

Failure Date: 02/15/2018

All 4 of my catalytic converters have had to be replaced (or need to be replaced - I've already replaced bank 1. Now bank 2 is bad) in the past 12 months or so and now my radiator is leaking into my transmission. I discovered there was a class-action lawsuit on the radiator/transmission issue, but I'm outside of the warranty period. With respect to the catalytic converters, I occasionally smell exhaust, but the check engine lights stay on. With the transmission, it started out as gear slipping, causing rough driving (which the dealership told me was the catalytic converter). Then, it started running slow out of first gear and hard shifting. I took it to a transmission place that pulled transmission codes and when they dropped the pan, the fluid looked like a milkshake. The rough driving/gears slipping didn't matter - it could be on the highway or in the city. I don't know the exact date in 2018 that I had the issue, but I've been dealing with this issue for a year.

The radiator was cracked where the transmission fluid is and it mixed with the antifreeze which caused both the radiator and the transmission to have to be replaced. The engine was on and vehicle was stationary when we noticed the temperature increased greatly and rapidly until it maxed out. The vehicle was leaking a mix of antifreeze and transmission fluid. We replaced the radiator but the damage was done already to the transmission. The vehicle was in motion when the transmission failed.

17 Radiator problem

Failure Date: 06/25/2016

My vehicle had problems in 2011 when a "warranty notice" was sent regarding a radiator problem. I took the car in and they found that it was a timing belt and did not change my radiator while it was under the extended warranty and had approximatey 70,000 miles. I now have 160,000 miles and my car is acting up again and the dealership advised me the radiator is cracked and leaking coolant into the transmission so I need both repaired or my car will get worse and can cause an accident. To me it appears that this defect with the car was from the inception and it should have been recalled because it was bound to fail and it should be fixed at Nissan's cost. My vehicle is still pretty good looking but I feel it is only a shell that I am driving because of the interior radiator flaw. They indicate that since no recalls were made I have to pay the total out of pocket. I missed the lawsuit in 2013 but am willing to file another class action lawsuit if a lawyer is willing to accept it. The vehicle was shaking when I was driving it on the freeway mainly and it felt like it was not in gear and pulling. These were also my concerns in 2011 when I took it in to be repaired and fixed, but they said I had no problems. Well I do now and I wouldn't have if they had fixed the defective radiator.

20 Radiator problem

Failure Date: 05/06/2016

We have a 2006 Nissan Pathfinder that has transmission failure due to a defective radiator. This is a known defect that Nissan should be held accountable for. We followed all recommended maintenance, most of which was at a Nissan dealership. The dealership was negligent in its inspection and repair of our vehicle. When we began to experience transmission failure and had both transmission and coolant contamination, they failed to diagnose the problem. Two Nissan dealership inspections in may 2016 outlined that all was well with our vehicle, even after we found that there was no transmission fluid on our dipstick, and it did not appear that the bolt to check the fluid had not been recently removed. Our family¿s safety was put at risk driving this vehicle for over a month, while it was experiencing transmission failure and risked engine failure due to heavily contaminated coolant. After a few weeks of symptoms, we looked online and were shocked to see the widespread manufacturing defect that has been reported. We took our truck to an independent shop who diagnosed the problem. The Nissan warranty was extended to 10 years or 160,000 kilometers for possible radiator assembly failure. Although our vehicle fell within the 10 year time frame, we were outside the kilometer range by 40,000 kilometers. Nissan canada and crown Nissan refused to extend the warranty to us. We feel the 160,000 km is far too low for a 10 year warranty. A recent Dodge warranty extension was 10 yrs, 240,000 km. Nissan put us in an unsafe situation, where they failed to diagnose the problem and we were out driving for several weeks, some of which involved towing our family camper on the highways. Nissan has been negligent on many levels and a recall should be extended to these faulty radiators.

While driving on interstate 25 in south denver, my Pathfinder began to sputter and stall. The engine started to overheat as I pulled into a service station about two miles away. I had it towed to christian brothers auto in parker colorado. A radiator part blew, the engine overheated and was destroyed. The steam from the plastic radiator part also damaged the main computer.

Approximately 8,000 miles later, my daughter and I were driving on I-70 near the vail, colorado exit, and the Pathfinder started to jerk violently on the highway going 65mph. I was able to pull over to the side of the road. Scary experience for us both. This happened today, 03/24/2016. Smoke was coming from under the car. I had it towed to avon auto in avon colorado.

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.

Failure Date: 04/12/2015

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 occured 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.
