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.
2006 Nissan Pathfinder transmission complaints
Page 2 of 16: complaints 11 to 40 of 450, newest first, as owners wrote them.
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.
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.
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.
There is a system design flaw with the 05-10 nissan trucks; pathfinder, frontier, xterra. The radiator houses both coolant and transmission fluid. When the radiator fails, it leads to coolant and transmission fluid mixing; resulting in catastrophic failure and premature destruction of the transmission. Our transmission was replaced with a brand new transmission after the original transmission failed at 89k miles. After the new transmission was put in, the transmission was destroyed at 90k miles and the issue was traced back to a cracked/ruptured radiator; leading to mixing of coolant and radiator fluid which in turn ruined the transmission. The cost of the initial transmission replacement was $6000; the estimated cost of replacing the transmission again along with the radiator and flushing the system and replacing the fluids is $8000. In both instances of transmission failure, it happened during driving conditions on a highway without symptoms of transmission issues. The worst part of this is not the cost. The worst part is that this known issue on nissan trucks should have been classified as a recall issue because the failure can happen anytime, especially during driving conditions and has the potential to cause a crash, serious injury, or death.
Transmission fluid leaked into transmission causing transmission and radiator failure. Was on mainroad at time and had to be towed to mechanics where upon learning this is a typical issue for these vehicles. Cannot drive vehicle and repairs are very costly.
My vehicle suddenly started to have a delay in acceleration when the gas pedal was pushed, and then would catch and lurch forward. I have been told that the transmission inner cooler ruptured and has ruined both the radiator and transmission. Further research indicates this is a known issue that nissan has failed to accurately advise owners about, or issue a recall. This is negligent and wholly unethical. Negligent in that the symptoms could lead to serious harm out injury, as there is no warning prior to the damage being done. Unethical in that now nissan gets to profit from their negligence, as it will cost $5,000 to remedy what could and should have been much less costly.
Tl* the contact owns a 2006 nissan pathfinder. The contact stated that the "overheated" warning indicator illuminated while driving approximately 25 MPH. The following day, the vehicle failed start. The vehicle was towed to an independent mechanic who determined that the radiator failed and caused coolant and transmission fluid to mix. In addition, the transmission control module failed. The mechanic stated that the engine had to be rebuilt and a new radiator needed to be installed. The dealer and manufacturer were not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 87,270.
Car overheated/no start, had SUV tolled to auto repair shop was told by techician was told the following. Radiator failed causing coolant and trans fluid to mix. Transmission control module failed causing vehicle not to start.
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.
Defective radiator from nissan, dropped fluid into the transmission. As a result, both the transmission and radiator had to be replaced. If the radiator was defected the transmission would still be in tact. This happened just reaching the 100,000 mile mark.
Transmission has went out due to factory default there's a recall on the exact issue that I'm having with my car I need to know if there's an extended warranty or something to remedy this because it seems to be a known issue
Radiator malfunction cracked transmission lines, mixing antifreeze into the transmission lines, contaminated the transmission, the transmission is ruined! Never informed about this defect in the radiator! Never no recall!
Catastrophic transmission and radiator failure due to co-mingling atf and coolant at 136,000 miles. Contacted nissan north america, they refused to help in any way, but acknowledged this as a "known" issue.
The radiator has broken and leaked into the transmission causing a complete failure in the system. Both must now be replaced.
The transmission would not shift into overdrive, so I took the vehicle to aamco. The transmission was contaminated with coolant from the radiator, requiring a complete overhaul including the transmission computer. Estimated cost of damages is $4600! My vehicle is in excess of the extended warranty, however this is a design flaw that should be corrected by nissan.
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.
I was driving my newly purchased used 2006 pathfinder and noticed that I could not get up to speed until I got up to 45 or 50 MPH noticed I had several error codes ended up that one was the transmission valve assy. Took it to transmission shop which tested the fluid and found that there was radiator coolant mixed with the transmission fluid. The car was great except for this issue. Now it barely drives only in 4th gear and I am told if I keep driving it that way it will burn it up. I need to replace both the valve assy and the transmission and radiator to solve the problem at a cost of 5k. I do not have the money. This is really unacceptable.
When I was driven my nissan I make a stop and then I try to accelerate but my car didn't respond so I took the nissan to the mechanic and he talk me the transmission was bad do I need a new transmission .I was very lucky because I was very close from home in city street other wise I would has to tow the car to the garage and put my family in danger
Radiator coolant leaked into the transmission $4000 car 10 years old however I had high mileage due to many road trips
Tl* the contact owns a 2006 nissan pathfinder. When the vehicle was taken to the alhambra nissan dealer in alhambra, ca for a routine oil change, the contact was also advised to have a transmission oil change. The technician performed an oil change on the transmission and the transmission failed eight days later. The vehicle was towed to the alhambra nissan dealer where it was diagnosed that the transmission and the radiator failed and needed to be replaced. The vehicle was not serviced due to the repair fees. The manufacturer was made aware of the failure and informed the contact that the vehicle was old in age and out of warranty. The manufacturer did not offer further assistance. The VIN was unknown. The approximate failure mileage was 123,000.
Radiator transmission cooler failure, causing transmission to fail
A known problem with radiator braking with coolant in transmission resulting in new transmission and radiator 4439.65. Nissan should be barred from selling cars in USA with such substandard products/
While driving on the highway, penultimate week. I observed loud engine noise, vigorous shaking and jerking and a reluctance in acceleration when I applied gas pedal​. I was a little bewildered as I have been very punctilious with the regular maintenance of my car. I gently pulled into a parking lot to avert any danger on the freeway. Upon exiting the car, I perceived a pungent burning smell. At this point, I knew it would be unsafe and pernicious to drive the car home. I immediately called for roadside assistance through my insurance company and had the car taken to my mechanic. He called back the following day with the most disheartening news. For some uncanny reason, fluid from the radiator was leaking into and contaminating the transmission. He vehemently pointed out that he had seen quite a few of the same ominous problems brought to his shop, involving mostly 2006 nissan pathfinders. I was given a quote of about $4500-$7000 to fix this problem. I purchased the vehicle from a used car dealer with approximately 117,000 miles. I'm currently financing the car and because of my student loan and exorbitant fees, I still owe a lot on it. Honestly, I cannot​ afford the repairs at this juncture. It is very rapacious and immoral of nissan to abdicate their responsibility and pass on the financial burden to innocent consumers​. These cars had factory defects and design flaws that nissan was aware of but chose to ignore. I enjoin anyone having similar problems and indeed conscientious members of the public to vociferously condemn nissan's action and force a recall. This is corporate greed at it's worst !!
Transmission failure due to faulty radiator. Vehicle is not drivable. Happened while in motion.
Tl* the contact owns a 2006 nissan pathfinder. On several occasions, while driving between 10-50 MPH, the transmission failed to operate as intended. The dealer diagnosed that the transmission failed due to contamination of the transmission from the radiator fluid acid. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 170,000.
Total transmission failure on i95 in connecticut ,10pm at night, at 55mph , with family in car. Coolant leaked into the transmission causing a total transmission failure. Nissan knows about this problem and did not contact vehicle owners to warn of the problem or offer suggested repair. Replacing the radiator would have been a $300.00 fix. Instead nissan offered no warning and the extremely dangerous transmission failure on an interstate at night happened. Total cost to repair was $4381, plus a week car rental.
I paid off my pathfinder last year. Just about 2 months ago after leaving a friends house the truck started turning on all the dash board lights, I didn't know what to expect. I drove it very slowly home not even a mile away, I turned it off and next day..my surprise it didn't turn on to take to the mechanic. I called the tow truck to take it in to nissan dealer and they found that the radiator fluid mixed with transmission oil and messed up the module too. They where originally charging me 7200 dollars to fix. I brought it back home and after when I was able to pay with credit I took it in to fix. They urged me to fix all at once because of a manufacturer defect on any of the above..most likely they said it could happen again.
The transmission and radiator fluid mixing and causing transmission to fail. I see that you have had many complaints about this issue and you choose not to help the consumers. This is a very dangerous issue and a very expensive repair. This is obviously a continuing problem and an extended warranty isn't fair to the consumer because this is a faulty issue with this model transmission/radiator.
The transmission and radiator fluids are intermingling and has caused my transmission to fail. It has ruined the transmission. It is my understanding that this has happened to thousands of the same make and model.
