Engine Cooling System problems of the 2005 Nissan Pathfinder - part 1

Have problem with cooling system leaking into transmission.

The contact owns a 2005 Nissan Pathfinder. The contact stated that the vehicle failed to start. The vehicle was towed to a mechanic, who performed a diagnostic test and notice a defective ems relay. The mechanic replaced the defective ems relay. After the repair the contact noticed NHTSA campaign I. D. 10v517000 (engine and engine cooling). The contact called the manufacturer to see if the vehicle was included however, the manufacturer stated that the vehicle was included in the recall. The contact never received notification for the recall. The failure mileage was 122,648.

2005 Nissan Pathfinder radiator assembly & transmission defect my 2005 Pathfinder was diagnosed with the Nissan noted radiator assembly defect. Radiator coolant and transmission fluid are mixing.

My 2005 Nissan Pathfinder was losing speed especially when passing vehicles on the highway, the 2005 Nissan Pathfinder would not go into reverse. I noticed that the car was not running properly for over 3 weeks. I took the Pathfinder to a transmission expert and they did diagnostic tests and the expert said that the radiator had a hole in it and radiator fluid went into the transmission and the transmission was gone. He showed me the transmission stick that showed me that radiator fluid mixed in with the transmission fluid. The transmission expert said that they have seen a number of Nissan Pathfinders with the same problem. A week later, I took my 2005 Nissan Pathfinder to another transmission expert for a second opinion, this expert did the diagnostics and confirmed that the radiator had a hole in it that allowed for radiator fluid to go into the transmission. He also stated that they have seen a number of 2005 Nissan Pathfinders with the same problem and he recommended that I go to a Nissan dealership to see what they say. I went sheehy Nissan in glen burnie, MD in which they did a diagnostic test and found that coolant mixing with the trans fluid causing improper shifting. The recommendations were to replace the trans assembly, radiator, and trans cooler. The service manager told me that Nissan had an extended warranty on the radiator for 80, 000 miles or up to 2013. I had 85,000 miles on my 2005 Nissan Pathfinder. I called Nissan USA and told them the problem and faxed the diagnostic invoice to them. Two weeks later they told me that they would pay for the parts and I would have to pay for the labor. Luckily, my insurance company paid for the radiator, trans, and trans cooler. Nissan has known about this problem for and refuses to do a recall on the radiator and this is unacceptable! this affects 2005-2007 Nissan Pathfinders and this is a safety hazard if the vehicle trans stalls or shuts off while driving on highways and roads. A recall is needed!.

I am filing this complaint since Nissan does not do anything with the problem to be fixed, I have a 2005 Nissan Pathfinder, when were on the road our car is having trouble shifting starts jerking, and were so scared that will not make it home because the way its acting we finally made it home and the CA would not reverse we look online and search what' causing the problem and read a bunch of complaint with the consumer at automotive. Com stating that the reson for the problem is the radiator fluid leaked into the transmission that causing the transmission to burn, called around with a bunch of auto mechanic and when I mention that I need my transmission replace the mechanic immediately said you know you need your radiator replace because that is causing your transmission problem I filed a complaint with Nissan and denied the complaint this should be in the recall because this is dangerous if you werent aware of the problem if your on the road hope you can help us with this problem.

Radiator leaks into transmission causing transmission to mess up. Nissan is aware of the issue and told me it happens on higher mileage Pathfinder but they only extended the warranty to 80,000 miles. I researched the 2005 Nissan Pathfinder and found that this is an ongoing problem that occurs with this year and model. I feel there should be a recall on this problem and Nissan should be held accountable.

Radiator coolant and transmission fluid mixing, causing major problems with vehicle. Hesitatnt shifting, or worse, no shifting or movement at all. Expecially dangerous on highway (interstate).

I own a 2005 Nissan Pathfinder. Nissan extended thier warranties on the 2005 Pathfinders to 80,000. The reason they did this is because they know thier defective radiators have been causing transmissions to go out due to contamination from the radiator fluid. Since I was deployed, I was unaware of the extention or the problem until my transmission started giving me problems in may of 2011. The other day, I tried to pull out of a gas station and I lost all accelleration due to the transmission slipping almost causing a serious accident. I have a Nissan complaint ticket but unless it is forced into recall, I will have to pay for my new transmission on a car I just recently paid off. As a consumer, I should not have to pay for someone elses design defect that causes major mechanical cost and safety issues. After doing some research, most customers are being told to come and have the transmission flushed for approx. 500$ to be told the transmission needs replacement. This defect needs to be addressed immediately before someone dies as a result of Nissans negligence in standing behind thier product.

2005 Nissan Pathfinder internal radiator leak causing the transmission to fail started with strong vibration between 40-45 mph. Dealer inspection states internal rupture of the oil cooler contaminating the oil in the transmission.

The contact owns a 2005 Nissan Pathfinder. The contact stated that while driving, the vehicle started shaking violently. The vehicle was taken to the dealer who diagnosed that the radiator was leaking coolant in the transmission, which caused it to be defective and needed to be replaced. The manufacturer was not made aware of the failure. The VIN was not available and the vehicle was not repaired. The failure and current mileage was 61,000.

The contact owns a 2005 Nissan Pathfinder. The contact stated that she received a recall letter for NHTSA campaign id number: 10v517000 (engine and engine cooling) and the vehicle was taken to the dealer for the repairs. The dealer discovered that the catalytic converter was defective and would need to be replaced. The manufacturer was contacted who stated that the catalytic converter was probably affected by an ecm failure but they would not pay for the repairs, only the component listed under the recall. The contact believed that the manufacturer should be held responsible for the repairs since they were was directly related to the failure as described in the recall. The vehicle was not repaired. The failure and current mileage was 120,000.

Since April 2011 my 2005 Nissan Pathfinder started to wraddling and vibration under the vehicle. After having it check by a machanic in may 2011 he stated that the transmission and coolant is missing together. The fluid was changed on June 26, 2011, that came out looking like chocolate milk and it is still vibrating at 45 and 64 mils per hour. I under stand that this is a manufactor problem for the way it was design and should be fixed by the car dealers and not the consumer. . . . The slenoid in the transmission jumps offline and once the vehicle is turned off and back on it resets and the vibration continue as you drive. . . The changing of the transmission fluid did not help the problem. . ,.

The contact owns a 2005 Nissan Pathfinder. The contact stated the radiator and transmission fluids were mixing together abnormally and causing the vehicle to stall. In addition, the vehicle would not change gears as a result of the failure. The vehicle was taken to the dealer who advised the contact to replace the transmission and radiator. There were no recalls for the failure. The manufacturer was contacted who advised that they will give her a return call within a few days. The vehicle was not repaired. The failure mileage was 102,000.

Nissan manufactured the 2005 Nissan Pathfinder with a faulty radiator that leaks radiator fluid into the transmission causing the irrepairable damage to the transmission. The car experiences vibration (which has loosened bolts & other parts on the undercarriage) along with shifting problems & hesitation when accelerating. Nissan extended the warranty to 8 years, 80,000 miles but the problem usual occurs at high mileage. My car has 104,000 miles & they will not cover the cost of replacing the radiator (or transmission). I only received a letter from Nissan a few months ago stating there may be a radiator leakage problem but did not advise of the problem with leaking into the transmission nor did it state symptoms to watch for. I have been experiencing symptoms but did not know it was related to this issue until I went online and found several complaints by other Pathfinder owners. I bought my car to the dealer and they advised that it was a different issue and then an hour later they advised it was the radiator issue. Since I am over the 80,000 miles, they will not pay for replacement. I have contacted the corporate office and was told I would hear from them in approximately 24-36 hours but that was 5 days ago.

2005 Nissan Pathfinder se with 86,000 miles starting having operational issues when running at 2000 rpm's. Was taken to the dealer for numerous services and was mentioned to service department. Service department said they could not find anything and that it wasn't anything to worry about. After several thousand miles the rough engine running at 2000 rpm's was becoming more evident. Service manager test drove the vehicle and immediatly knew what the problem was as they had many other Pathfinders in for the same problem. We were told that the radiator seal was leaking fluid in the transmission and that the radiator needed to be replaced as well as a transmission flush to the tune of $850. 00. Nissan representative appeared at dealership and was notified of the problem however refused to cover the problem saying that it was our problem because it exceeded the 80000 mile extension on the radiator. Nissan never notified us about and extension on the radiator in the first place. The service manager aslo indicated that he could not puy a warranty on the transmission that received the radiator fluid in the transmission. Nissan has known about this problem but refuses to own it. They have lost a very good customer who was about to purchase another Nissan vehicle.

Radiator cracked and leaked into transmission which lead to transmision failure.

I have a 2005 Nissan Pathfinder 4x4 se off road with 115,000 miles . Beautiful vehicle but beginning to have problems the fuel guage will go to empty when full , also having hesitation about 40 miles an hour . I read about the horror story with radiator problem causing transmission problem . I have an appointment at a Nissan dealer this weekend for the recall on the ecm so I will have further info on the hesitation , Nissan recalled the fuel gauge problem but limited to 72,000 miles vehicle only ,I think they should up hold the Nissan rep and take care of these problems also the transmission problems due to faulty parts . These problems are not normal wear and tear .

The contact owns a 2005 Nissan Pathfinder. The vehicle was taken to the dealer for repairs when they informed the contact that the radiator was leaking and needed to be replaced. The dealer replaced the radiator. The manufacturer filed a complaint and the contact was awaiting a response. The current mileage was 91,692 and the failure mileage was 90,586.

2005 Nissan Pathfinder radiator coolant leaked into transmission, ruining it. They need to recall this. The way they designed the radiator ends up ruining the transmission, which is not the owners fault.

2005 Nissan Pathfinder has reportedly had multiple complaints regarding the cooling system leaking into the transmission, causing rust and subsequently, a failure in the transmission. It is reported that the radiator and transmission can be replaced to the tune of $5000-$8000 but does not fix the problem - will have to be done again in the future. Transmission slips between 40-60 miles per hour and loses acceleration. Dangerous behavior that can cause serious accidents and injury. Nissan is ignoring the problem and won't respond to complaints. Have extended warranty to 80,000 miles but of course the majority of owners experience this issue at 100,000 miles or 5-6 years.

The contact owns a 2005 Nissan Pathfinder. The contact stated that while driving 40 mph, the vehicle suddenly stalled; there was no power steering or power brakes. The contact was able to drive home and to avoid a crash. The vehicle was taken to an authorized dealer where the contact was informed that the ignition power distribution module needed to be replaced. The contact referenced recall 10v517000 (engine and engine cooling) and was told that the recall did not take effect until December 2010. The failure mileage was approximately 77,000.

I brought car to the dealer for service and asked for the tranny to flushed they said the radiator had a leak and there was coolant in the transmission. They offered to replace the radiator and flush the system for $1,000 but didn't think that would help. The dealer wanted to replace the transmission and radiator for 8-10k. I ended up taking a loss and trading in the car couldn't see putting that kind of money into a 5 year old car. After looking on the internet found hundreds of people having the same issue very disappointing Nissan doesn't stand behind their product.

We were driving in our 2005 Pathfinder when the car decided to decrease speed all by itself after we pulled out into an intersection with traffic headed our way. Took the car to Nissan dealership was told coolant leaking into transmission due to a defected seal in the radiator to fix the problem ecm,tcm, transmission and radiator need to be replaced about 7,000 to fix the problem Nissan need to correct there mistakes not recall one component that got fried because coolant leaked on it that's not going to correct the problem. I cant believe we have to wait for someone to loose a love one before action is done we were second away from that, seriously. Not a joke Nissan needs to stand up for there mistake this is America right don't we have rights to a safe auto for our children after paying alot for a car that suppose to be safe just google 2005 Pathfinder complaints and see how many are really out there 93% transmission problem on the 2005 same thing coolant leaking into the transmission make Nissan recall these cars and fix the problem we work hard for our country and deserve quality what if this was your family Nissan you have your family in one of these car think not!!!.

2005 Nissan radiator and transmission failure. Defective radiator causes engine coolant to leak into transmission which may fail at any time. Driving at highway speed, entering traffic, merging or entering intersections causing dangerous conditions as the vehicle fails to move, decelerates quickly or the transmission slips badly and fails to accelerate. Hundreds of incidents of failures are reported on the internet. An apparent design/manufacturing flaw in the radiator causes the condition. Nissan has taken no responsibility or corrective action. Thousands of unsuspecting consumers and their families are at risk each day driving or riding in these vehicles. Consumers are left paying thousands of dollars for replacements.

The initial problem was that the vehicle overheated. Further investigation revealed that the transmission cooler inside the radiator had broken. This flooded the coolant system with transmission fluid, which then circulated through the engine. The coolant/water mix also leaked into the transmission and caused the transmission to fail. Corrective action taken - replace radiator, all hoses, and transmission.

When our 2005 Nissan Pathfinder started to make a grinding noise during gear shift at 40 mph and 60 mph, we immediately took it to the Nissan dealership only to be told that a problem with the radiator was causing coolant to leak into the transmission, mixing with the transmission oil and destroying our transmission. This was on August 12, 2010. We were told we would have to replace the entire radiator and transmission at a cost of over $4500. 00. We could not understand how coolant could be leaking into the transmission, so we immediately contacted Nissan north America and filed a complaint. This kind of damage should not occur due to normal wear and tear. We were informed that not enough complaints had been filed but they would keep a record of our call and we would be contacted if they ever did a recall in the future. Still confused about what was causing this problem, we decided to get a second opinion at another Nissan dealership, less than 15 miles away from the first. This was done on August 30, 2010. We were told the same thing, the coolant was leaking into the transmission, but they wanted over five thousand for the same repair. Before making a final decision, we decided to research this issue further. We were amazed to find over a hundred complaints online, all from owners of 2005 Nissan Pathfinders, and all complaining about the thousands of dollars they had to pay to repair both radiator and transmission for the same problem we, too, were experiencing. With no help or acknowledge from Nissan, we went to an outside mechanic and had the work done at a much lower cost.

My 2005 Nissan Pathfinder began to shutter then jerk back into normal driving as it reached speeds of 60-70 mph. It was very sporadic in the beginning, but started to happen more frequently and at lower speeds for a longer period of time. I brought the truck into Nissan with 70,000 miles, at which time I was told that the radiator leaked into the transmission causing the need for both to be replaced at the cost of $6700. 00. I did alot of research and discovered that hundreds and hundreds of people with the 2005 Nissan Pathfinder with approximately the same mileage (just after warranty expires) are experiencing the same issues. It seems as though a faulty radiator system was installed into these vehicles. They kept my truck for 12 days while trying to decide if they would offer assistance with fixing my 5 year old vehicle. The end result being, that they would pay to replace the transmission and I would pay to replace the radiator as well as the labor costs. I was told that this did not occur as a result of anything I did wrong. I asked why a recall isn't being done, at which time I was told that the number of injuries or deaths was a major factor in that determination. Although I was not injured, this is a huge financial burden to take on for a vehicle that is only 5 years old. Nissan needs to take responsibility and stand behind the parts they put in their vehicles!!.

Vibration in transmission, coolant in transmission oil.

My transmission totally went on my 2005 Nissan Pathfinder. It would not start. The computer shut the car down b/c the transmission was not working. I was stranded with my children at a shopping center. I took it first to a transmission specialist. He could not repair it b/c he could not get the parts from Nissan to fix it proper. He said he had seen 18 of these 2005 Pathfinders with the same issue. It happens at 60,000-120,000 miles. I took it to a dealership. They knew right away. I was told it was a design flaw, the coolant from the radiator leaks into the transmission causing the transmission to go out. I was told I had to replace the radiator and hoses, so this would not happen again. Nissan made changes in the radiator to correct their mistake. I had to replace my transmission, temperature gauge, and radiator with new.

2005 Nissan Pathfinder s/n [xxx] . Engine coolant leaking into transmission due to failure of oil cooler causing transmission failure. I have read over 100 complaints on this same issue and Nissan will not assist in the repairs. I was informed it would cost $5,149. 00 before taxes to get this vehicle repaired. Nissan knows this is a problem. The dealership I took it to shook his head and said he currently has one in the shop for the same reason, but they won't stand behind their product. To make matters even worse, they are replacing the faulty part with the same defective part. Isn't there any way we can get this pushed through so Nissan would issue a recall on this and take responsibility for their mistakes? please call me @ [xxx] . I woulod like to know what I can do to help the many people in my same situation. Thank you for your time. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

Transmission problem I had noticed the transmission slipping on my 2005 Nissan Pathfinder. Took it to my local mechanic who did not think it was a serious problem. It gets worse the longer you drive it, but agreed it was not right and told me to take it to a transmission specialist. I took it immediately, he put the car on the on computer and got error codes back, car is fine. . . . I explained my problem again and he decided to take it for a test drive. He wasn't gone 10 min when he pulls in to his garage with tran fluid pouring out from under my car. He needs to use the fire extinguisher as the fluid is so hot it is catching on fire. Now after all has settled down he does get errors on the computer but nothing specific about the problem. He has yet to tell me what caused it except that it is internal. There are so many problems with the transmission on this model and make someone has to do something. What if I was driving my children on the highway when this happened. Would we have all gotten out!.

2005 Nissan Pathfinder. Transmission failure due to coolant contamination. Radiator had to be replaced as well as the transmission . Many other problems with car. The fuel sending unit, air conditioning/heater fan, drive shfts/universal joints, brakes. Just about everything has failed and cost me massive amounts of cash.

2005 Nissan Pathfinder defected radiators leaking into transmission, rusting components leading to transmission slipping and failure, I was on the mass pike highway going about 60 when my Pathfinder just pull back like you dropped it in low, 18 wheeler almost drove right threw my back of Pathfinder, this has happened more then one time, sometimes while stopped in traffic it feels like the transmission is pulling forward without putting your foot on the gas, I have done some research online to find the same problem many others are having in the radiator there is transmission fluid( look) for white milky substance also antifreeze going into transmission, please search the web for 2005 Nissan Pathfinders complaints and problems, this is vary dangerous to be driving it is unpredictable when it happens and I was told just a matter of days before I will have to replace both radiator and transmission, this is a total defect on Nissan, not fair at all, threshold be a recall on this a big safety issue could cause a serious accident.

My 2005 Nissan Pathfinder with 55,000 miles. I notice a vibration under the vehicle which would last for 2-3 seconds everytime I would drive it. I thought nothing about it, until it got worst. Now the vehicle stalls and vibrates more frequently while traveling on highways and major roads. I went on-line to research the problem and discovered the cause was from a leak from the radiator into the transmission and caused the slippage and the vibrations. Thousands of other people who own a Nissan Pathfinder had similar problems and have gone to the Nissan dealership and complained about the issue, as I had. The only thing Nissan will do is replace those parts, but we the consumer will have to pay for it, although it is clearly a manufacturer issue in relation to Nissan using inferior quality of parts. It will cost me $5,600 for parts and labor to fix a Nissan problem.
