The mechanic repaired brake line and replaced the battery however, the failure recurred with the battery. The vehicle was towed to the same independent mechanic who was unable to diagnose the second failure. The vehicle was then towed to anderson Nissan (3842 az-95, lake havasu city, az 86404) who diagnosed the vehicle with a loose electrical connection with the battery relay. The vehicle was repaired and returned to the contact however, the failure recurred the next day. The contact had the battery replaced once again however, the battery failed for the third time. The contact had the vehicle towed back to the same dealer where they discovered a defective radiator which caused fluid to leak into the transmission. The vehicle was then diagnosed with engine failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 90,000.

Tl-the contact owns a 2006 Nissan Pathfinder. The contact stated that the "over heated" warning indicator illuminated while driving approximately 25 mph. The following day the vehicle did not start. The vehicle was towed to an unknown independent mechanic, they determined that the radiator failed causing coolant and transmission fluid to mix, transmission control module failed also causing vehicle not to start. The engine had to be rebuilt. And a new radiator installed. The dealer was not notified of the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 87,270. Bp.

In the last 4 years I've replaced emissions system brakes rotors air conditioning system exhaust system radiator and transmission. Car was vibrating shaking cutting out leaking exhaust fumes and emissions system failed.

Tl the contact owns a 2005 Nissan Pathfinder. The contact took the vehicle to the dealer (melloy Nissan, 7707 lomas blvd ne, albuquerque, nm 87110, (505) 545-6420) for a routine oil change and inquired about failures with the transmission; however, the dealer found no failures. The contact stated that the vehicle's transmission malfunctioned and would not shift gears. The contact took the vehicle back to the dealer and was informed that the radiator was cracked and the fluid seeped into the transmission fluid. The repair cost would exceed $5,000. The manufacturer was not contacted. The VIN was not available. The failure mileage was 81,957.

The issues with the vehicle began at 133834 miles. When driving, at times it would vibrate out of nowhere. After a stop, it would shift up hard or fail to downshift and then hit hard when it finally would go in to gear. Once I took it in to a mechanic, the following codes came p1731 - 1st gear logic error, p0430- cat efficiency bank 2, p0455- evap system leak large. The recommendation was "tear down". In the end, I had to replace transmission, radiator, torque converter, valve body, valve body solenoids, catalytic converter bank 2, exhaust gaskets, oil pressure sensor, and oxygen sensor. With a total cost of $4,824. 65. I will upload the services my Nissan Pathfinder had to have.

Takata recall im writting this complaint in regards to my 2005 Nissan Pathfinder se. On 10/2/2017 my vehicle gave me some issues of not wanting to turn on. After talking to several mechanics and all giving me the same diagnosis and advising me to take it to town north Nissan in austin texas. The service agent (luis cruz) also gave me the same diagnosis (the module ipdm) needed to get changed. They gave me a price on the cost and told me the date my truck would be ready for pick up. My truck was in their shop since 10/25/2017 and they told my my car would be ready 10/31/2017 after 12:30 pm. So I called to get an update so I could pick up my truck. After all this time (luis cruz) told me that my truck actually needed a new transmission. That the transmission fluid and the radiator mixed totally ruining my engine. And that I would have to pay ($5,900) to fix it. I did some research and came across and article that says that the nccc has received several complaints in regards to the same issue with the same vehicle I have. I need some help on how to approach Nissan in regards to this problem. Because if this is something that Nissan really knew about they have to be liable for the repairs of my car. Please help. . . .

The contact owns a 2005 Nissan Pathfinder. While driving 55 mph with the cruise control activated, the rpms accelerated and the vehicle stalled without warning. The vehicle was able to restart on the first attempt, but the gears failed to shift. The vehicle was towed home. It was diagnosed that the transmission was flooded with water and the radiator needed to be replaced. The radiator was replaced, but the failure recurred. The manufacturer was made aware of the failure. The failure mileage was 179,000.

Radiator coolant leaked into the transmission rendering useless. Corroded and destroyed whole interior of transmission .

I was stranded in a parking lot because my car would not start. After having it towed to the dealership, I find out it is the "intermix" between the radiator and the transmission. I never received any information about this from Nissan, but now understand it was a known and frequent failure - by design. Essentially, after 90,000 mile, the car is worthless because of this issue. After paying $5,000 for the repair, I drove off the lot only to have my fuel pump fail. Literally, I drove off the lot and the engine began misfiring. Unbelievable.

Started loosing speed while drivingnon the interstate with my daughter in the SUV with me, so scary. But I managed to coast to the nearest exit roilight in time fokir it to get to 0 on odometer. Then had it towed to my home. Few days later took to two different auto repair shops(towed to 2nd shop because SUV would not go pass 20 and it would just stop once down to 0)who inforned me there were transmission issues, final shop said the radiator ruptured causing water, transmission fluids, and etc to all mix which has caused transmission to go bad my options are to rebuild, but another transmission or let the SUV go. . Upongoogling to seeb iif others have or had this problems I'm totally not alone and yes I'm pass the 50,000 n 100,000 range however I still think som etching shouldbe done, being I took n ttrace very gd care if my SUV only allowing Nissan to repair and maintenance my SUV. I was told to repair this will cost me 3900 plus. I shouldn't have to pay any to be honest but done type iif help would be greatly appreciated for not only me but everyone experiencing this issue.

I took my 2005 Nissan Pathfinder into the shop because it was having trouble shifting gears at highway speeds. I later learned the bad news that the hoses in the radiator have failed causing coolant to cross contaminate and mix with transmission fluid producing a toxic sludge that ruins the radiator as well as the transmission. I was told that $4,000 later I would need a new radiator, new transmission and new hoses. The service technician also told me that this problem is very common in 05-06 Pathfinders. After going home a quick google search revealed that tens of thousands of cars have actually dealth with this problem and there was a lawsuit brought against Nissan for these problems. Unfortunately I never knew of such a lawsuit and now that I have the very problem it's too late to do anything about it. That type of service by companies for selling faulty products to their consumers is really too sad.

Car died on me this morning! mechanic said transmission as well as radiator. Plus coolant and tranny fluid leaked into each other. Something that looks like lawsuits and many others have complained on. Dealership wont fix it!.

Contamination of transmission fluid on 2005 Nissan Pathfinder. Color of coolant is purple and cloudy in overflow and radiator. Transmission has started shuttering between 35 - 45 mph. Symptoms began at 130k miles.

I purchased a used 2005 with apprx 134,000 miles. I returned the vehicle the following Monday for a cracked radiator. The radiator was replaced. The vehicle continued to have shifting issues. 3 weeks later it was given a diagnosis from a certified Nissan service shop as "needing transmission replaces as a result of coolant leaking into the transmission from crack radiator" I was estimated over $7000 worth of repairs because of the radiator cracking and leaking coolant.

Ecm replaced under recall. Radiator/transmission replaced @ 96k miles under "extended warranty. " transmission replaced 2nd time 1 year later. Transmission hoses replaced twice (during same time period). Now - 103k miles - check engine light came vias solenoid valve, bank 2 catalytic converter, & oil pressure sensor switch all need replaced (possibly related to ecm relay issue).

The contact owns a 2005 Nissan Pathfinder. While driving 40 mph, there was an abnormal vibration to the vehicle. The contact stated that the accelerator pedal was depressed and the vehicle stalled. The vehicle was taken to the dealer where it was diagnosed that the radiator fluid leaked into the transmission. The contact was informed that the radiator, transmission, and transmission cooling lines needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 92,000. The VIN was not available.

The radiator cooling system leaked into my transmission and caused it to stop working so I need to replace it at a cost of $5400 for transmission and radiator is $1000. I was in motion when I first felt a trimmer every now and then for about 3 weeks then it got worst at any speed or surface and places. Nissan will not help me on this because it has 120497 miles on it. I explained to Nissan if they had sent out notice about this I would have gotten my car fixed before now. I can not get anyone to help me on this. I have read on the internet that I am not alone on this situation. Can anyone help. I have bought several new Nissans but I will buy no more and I really loved my Pathfinder.

There is a leak in my radiator which as gone into my transmission rendering it inoperable. Mechanics recommend to replace the entire transmission due to this massive design flaw Nissan has been well aware of for years. I¿ve spoken with my Nissan dealer as well as the dealer that looked over the car when I purchased it and both said it¿s a massive problem and customers have no way of knowing if or when it could occur, and therefore no way of preventing it. I understand the north carolina consumer council filed a petition back in 2012 and that the complaint volume has been tremendous on this issue. I hope the NHTSA comes to the conclusion that this part should have been recalled. I have no family vehicle now and cannot afford to pay $7500 for a new transmission, that had no issues at all until the defective radiator got a hole. Thank you.

After receiving a complimentary multi-point inspection from the local Nissan dealership, my wife told me that on the way home that the transmission seemed to not want to shift properly. Went to check transmission fluid and found that the dipstick is locked into place. Did some quick research to find out how to check fluid level and then found out about issue with Nissan Pathfinders radiators having a problem with leaking coolant into the transmission cooling system. Checked radiator and found frothing foam on the inside of the pressure cap indicating that the radiator had failed. Contacted dealership and asked them why the section of the inspection for the cooling system and transmission system were checked as "ok". Did not receive an answer. Also, we were never notified by Nissan about the issue with radiator in our Nissan. The vehicle is currently parked since the dealership said it would cost up to $3000 dollars in repairs under the agreement reached. I do not understand why this was not a recall. This situation could of caused a catastrophic failure of the transmission at speed while driving or catastrophic failure of the engine because of lack of cooling causing the engine to seize up at speed while driving.

Tl- the contact owns a 2005 Nissan Pathfinder. The contact stated while driving at approximately 15 mph, the accelerator pedal was depressed but the vehicle failed to accelerate. The contact mentioned that the vehicle jerked before resuming acceleration. The failure recurred intermittently. The vehicle was taken to a dealer where it was diagnosed that the transmission fluid had leaked into the radiator, causing the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 160,000. Jo.

Transmission cooler attached to radiator cracked causing coolant to leak into the transmission leading to failure to accelerate the vehicle when needed and complete failure of the transmission.

Radiator cracked and contaminated the transmission fluid. I had to replace the defective radiator and flush/refill the transmission fluid.

Vehicle contained a defective radiator cooler tank that ruptures and forces coolant into the transmission through the cooler lines. When the coolant mixes with transmission fluid it creates a frothy liquid that eats valves, erodes seals and causes corrosion. It’s toxic, irreversible and killed the 5-speed automatic transmission. This problem was listed as the 2nd worst problem on carcomplaints. Com's "top vehicle problem trends of 2012". Why is this not a recall?!.

The radiator on my Pathfinder has cracked and allowed coolant to get into the transmission fluid. This has ruined not only my radiator but also my transmission.

One morning on the way to daycare my 2005 Nissan Pathfinder could not shift above first gear. I drove 8-10mph with hazard lights on to the dealership, Nissan of portland (122nd Ave). They told me it had cross contamination due to a "known faulty part" but that my warranty had expired in December. I bought the car from that dealership 18 months ago. They did not tell me at the time of purchase about this defect nor about the warranty, rather waited until they could charge me $5100. 00 to replace the transmission and radiator. This is so wrong! Nissan corporate should be ashamed of themselves for not fixing this for free whenever it manifests itself (or before) and dealers can not be allowed to sell cars without disclosing known material defects. Oregon law ors 646. 608 agrees.

Nissan needs to formally recall several vehicles with radiator/ transmission problems. In my case while I was driving my vehicle suddenly came to a stop while I was on the road driving at a speed of 55 mph. My vehicle shut down and I tried to turn on luckily it turned on and began to run again. I pressed on the accelerator it did not run more than 20 mph. I decided to tow my vehicle to a local mechanic to have it diagnosed since I was terrified of it shutting down once again in the middle of the road. My mechanic diagnosed my vehicle and concluded that fluid from the radiator had leaked into the transmission. Nonetheless, he expressed to me that this was nothing new he had seen with these vehicles. He told me that he had fixed a couple in just this last year. According to his past clients Nissan failed to do anything to correct the problem regardless of the potential hazard. I visited the dealer in which I have purchased the vehicle and explain the service man my concern. He clearly told me that my warranty was over and that the lawsuit against Nissan to be reimbursed had ended in 2013. I told him that my vehicle frequently comes to their service center for maintenance and if they were aware of the failure in theses vehicles once they reach their 100,000 miles why did they fail to correct the problem before it occurred. It surprises me that Nissan failed to inform any of its consumers of the problem when it was going through a lawsuit. He then proceeded to tell me that he could not help me and referred me to corporate office. I was told I would be called within two days. I received the call back from Nissan simply telling me my case was reviewed and they could not do anything due to the fact that my warranty is over. Nissan is putting the lives of their consumers in danger and is hiding behind their warranty guidelines to avoid correcting their engineering errors.

Me and my 6 month old daughter were going down the road when my car lost all power and was like it had been shifted into neutral. My brakes weren't working properly but I got us off the road and had the car towed. After our repair guy checked all the wiring and ran test and pulled the transmission pan off the radiator coolant had leaked into the transmission full resulting in the gears messing up and the entire car undriveable. We knew about this problem and had contacted Nissan 6 months prior to check the recall and was told this vehicle had been fixed. . . . Obviously not. If it had been fixed it wasn't fixed properly or it would not have failed again many trips have been taken since then and now we are over 100,000 miles and it's a $3800 fix because Nissan either lied and it was never fixed to start with or didn't correctly fix it the first time.

I began to hear a noise and hesitation in gear change. Told tires but continue to hear. Had a oil change at twin city Nissan. Rep advice coolant in transmission would charge $3000 to repair and warranty on radiator expires soon. Radiator and transmission and fluids flushed for $3000 cost to me. Contact 1800 Nissan 1 and told over 368 complaints its manufacturing defect he advice can't. Help.

The contact owns a 2005 Nissan Pathfinder. While driving approximately 45 mph, the transmission seized and the check engine warning light illuminated continuously. The vehicle was taken to a dealer where it was diagnosed that the radiator fluid leaked into the transmission, which caused the failure. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was 158,000.

The vehicle began a slight shudder when shifting and within a few days while passing a truck on the freeway at 70 mph it shifted very hard and responded as if it was in neutral. Any application of the accelerator caused high rpm but gave no additional power. I was forced to put on my emergency flashers and maneuver through three lanes of traffic as I had lost all power and could not was just coasting along the freeway. It was a very dangerous situation that fortunately ended safely no thanks to the car. It was later determined by my mechanic that the radiator fluid had mixed with the transmission fluid and caused the transmission components to fail. After spending $1000. 00 on the first repairs to replace the radiator and flush the transmission 3 times it ran for a week and began shifting very hard again. It is now in the shop being considered for a transmission replacement. Hearing about the investigation and similar experiences by others it is a wonder why this issue has not been officially deemed a safety recall seeing as how my safety was definitely in jeopardy at the time of the failure.

Nissan dealership just diagnosed that my radiator was leaking into my transmission. This was problematic because the radiator coolant has damaged the transmission. In April of 2014, I had had my 2005 Nissan Pathfinder to the same dealership for the same issue and they had flushed and replaced my transmission fluid.

Got recall in mail for radiator and transmission recall which we had to pay for?!?! over $2000. To replace the radiator and not even 3 months had gone by and have had the truck to the garage 3 times due to damage from transmission. Got in truck to go to work today yup you guessed it transmission is now shot put in drive and doesn't go. Totally unfair Nissan should have replaced it when the recall came out. Why should the consumer pay for there screw up? new transmission $5000. Will never buy Nissan again and will make sure I tell everyone. So far to date $5000. To try to fix up Nissan's mess and then I'm to spend another $5000. On there mistake. Ha total bull!!!!! they should have stood by there product and replaced everything at no cost to the owner!!! very unhappy!!.

Radiator failure allowing transmission fluid to mix with antifreeze causing transmission failure. Radiator failure due to crack in transmission cooler. Is manufacturing defect, should be Nissan 's responsibility to fix not the consumer.

I had the vehicle's tires replaced and within a few days there was a shudder like rumble strips. I took the Pathfinder back to have the tires looked at. Repair shop replaced the wheel bearings. The shudder still persisted. I talked to a friend who owns a transmission repair shop and he told me about the radiator leak/transmission problem. He said to check the engine coolant for milkiness and search online. The coolant is milky and after reading all the other complaints, my family is scared to use the Pathfinder. I think a recall should be issued because the transmission is failing because of failure of the cooling system not wear and tear. A failing transmission is more likely to cause an accident than a failing cooling system. Also, Nissan's extended warranty seems to end to early to be effective.

I was driving along a local road and all of a sudden, my engine starting revving and the car started slowing down. I stopped at a red light, but when it turned green, my car wouldn't move for about a second or two when I pressed the gas peddle. When it did move, it crawled along at 20 miles an hour. I managed to get it home and took it to the mechanic on Monday. I was told that coolant from my radiator leaked into my transmission and destroyed it. On researching this, I discovered that this is a known issue in 2005 - 2010 Nissan trucks but Nissan will not cover the cost of repair even though they are aware of it and did not issue a recall.
