Transmission Fluid Leaking problems of the 2007 Nissan Pathfinder - part 2

Tl- the contact owns a 2007 Nissan Pathfinder. The contact stated that after attempting to accelerate, the vehicle hesitated to move. The vehicle was taken to the dealer. The technician diagnosed that the radiator fluid had leaked in the transmission. No repairs were made and the vehicle became inoperable after some time. The manufacturer was made aware of the failure. The failure mileage was 135,000. Pam.

This is all after the vehicle was serviced (by Nissan dealer) for the known radiator leaking coolant into the transmission fluid. Repair back in may 2013 with approx. Mileage 68000. Now vehicle has about 75000. Driving home from dinner with wife in moderate traffic. Herd a clunk and car would not accelerate. Barely made it home. I let vehicle cool down and removed the radiator cap and found thick cream like fluid which is a definite sign of oil based fluid contaminated with water / glycol. Seems to me that Nissan did not replace or fix the leaking radiator. Driving a vehicle that behaves in this manner can not be safe to drive. Back to the shop (dealer) tomorrow.

Vehicle began to vibrate at speeds of approx 45 mph. Over a short period of time, the condition worsened - the vibrations became more aggressive and began to occur at higher speeds. After investigation by Nissan, they advised that there was an issue with the radiator and possibly transmission that was no longer under warranty because I was outside of the 100,000 mile limit. The coolant is leaking into the transmission fluid cooler line and ultimately right into the transmission, thereby causing damage that may or may not be repaired with a new radiator and transmission. Apparently, this is a know issue with these vehicles and Nissan neglected to alert consumers. At this time, the vehicle is inoperable.

Note: affected parts are transmission and radiator (not sure what category those fall in) I purchased a 2007 Nissan Pathfinder from a Nissan dealership less than 3 months ago. Immediately after purchasing I noticed what seemed to be a minor lack of power or cutting out when coasting downhill. I mentioned it to my sales rep, and again when I had to take the vehicle back to the shop on two separate occassions for a tire pressure gauge and rear door handle problem. I had never owned a 4wd before and it was dismissed as no big deal since it still drove okay. Then last week, over labor day weekend, my car overheated and immediately discharged a grey milky substance from the radiator without warning. It had not overheated prior to this. I had my car towed to the dealership. They informed me that both the transmission and the radiator need replacing to the tune of $6,600. The cause being the radiator fluid leaking into the transmission. This repair is over half the value of the car. I never would have purchased the vehicle had I known about the defect. At a minimum I would have insisted it be covered by warranty. I paid full retail price for the car not knowing of this defect. While I'm grateful no one was injured by this defect this time, I have no means to pay the repair costs and owe $13,000 to the bank for a vehicle I cannot drive or resell.

Vehicle was hesitating when shifting gears. Daughter pulled car in driveway, there was a burning smell. Then all of this fluid leaked on to the driveway and the car would not go into gear. Pathfinder at dealership now to be repaired. Will cost me $3000 for a known defect. Doesn't seem right that the consumer has to pay for the mistakes of the manufacturer. There should be a recall with this issue - and Nissan should be the one responsible for paying the entire amount.

Radiator failed, leaking antifreeze into transmission. This mixing of antifreeze and tranmission fluid caused transmission to fail. The violent vibrations and rough shifting is a safety hazard and Nissan should recall all models with this radiator. I had to pay $2500. 00 to have this defect repaired.

Transmission starting slipping then started jerking while driving then it started overheating. Took it to a Nissan dealership because I bought the extended warranty that was supposed to cover the powertrain. They told me that the cooler cracked which caused the radiator fluid to leak into the tranmission and messed up the radiator, which is not covered by the powertrain warranty because the radiator cooler was not part of it. The dealership wants to charge over $6000 to fix it.

The radiator leaked fluid into the transmission cause damage to the transmission rendering it useless. This is a known design defect with the 2007 Nissan.

The contact owns a 2007 Nissan Pathfinder. The contact was driving 50 mph when the transmission began to jerk without any warning. The vehicle was driven to a safe location and inspected. The vehicle was taken to an independent mechanic who advised that the radiator coolant leaked into the transmission fluid, which contributed to the internal damage of the transmission. The vehicle was not repaired. The manufacturer was notified of the problem. The approximate failure was 110,000.

The radiator fluid is leaking into the transmission fluid and causing significant "rumbling" noises. The vehicle does not shift correctly.

The contact owns a 2007 Nissan Pathfinder. While driving approximately 55 mph, the vehicle began stalled while the contact was attempting to accelerate. The vehicle was taken to the dealer for diagnostic testing. The technician advised that the valve body and radiator needed to be replaced due to a leak in the radiator and the coolant was intermixing with the transmission fluid. The manufacturer was made aware of the failure and advised the contact that the vehicle was not included in any recall. The vehicle was not repaired. The failure mileage was 101,000 and the current mileage was 104,000.

I started having a sudden jerking in my 2007 Nissan Pathfinder when driving down the highway. When I took it into a Nissan dealer they diagnosed the problem as a failer with the radiator internally and externally which allowed leaking coolant into my transmission fluid causing both radiator and transmission failure. The dealer now states that I need to replace both items or trade it in. . . . . Come on Nissan you have a major problem. We need a recall. . . . . . .

The contact owns a 2007 Nissan Pathfinder. While driving 50 mph, the vehicle shook violently. The contact released the accelerator pedal and had to accelerate again very slowly. The failure occurred multiple times. In addition, the air bag warning indicator was constantly illuminated. An independent mechanic stated that there was cross contamination with transmission fluid leaking into the radiator and coolant entering the transmission. As a result, the transmission failed. The radiator was replaced and flushed; however, the failure persisted and the radiator had to be continuously flushed of transmission fluid. Additionally, the contact asked the dealer if the vehicle was included in NHTSA campaign number: 08v690000 (air bags), but the dealer stated that the recall was nonexistent. The manufacturer was not notified. The approximate failure mileage was 80,000.

While driving down the highway my husband and I experienced loss of power and had to pull onto the side of the road. We were towed from there to the mechanic who explained to us that the internal radiator had leaked fluid into the transmission causing failure to both. Since our warranty was outdated we are now out 6000$ and are struggling to fix this. I am very frustrated and disappointed in the vehicle. We had our children with and I am very glad that we were not at a busy intersection or interstate.

The contact owns a 2007 Nissan pahtfinder. The contact stated that while driving 40 mph. The radiator failed. The vehicle was taken to the dealer, who stated that the radiator, water pump, radiator thermostat, and transmission were damaged due to leaking radiator fluid. The dealer also stated that radiator needed to be repaired. The contact stated that this was the second occurrence of the same failure. The vehicle was taken to the dealer who diagnosed both failures. The manufacture was notified and offered no assistance. The failure mileage was 71,000 and the current mileage was 122,000.

I have manintained my car. In June, my Nissan dealership charged me $1500 after I reported a jolt in the transmission. I brought it back 08/10/2012 and they said the transmission needed replaced. I took it to another shop and they said the radiator fluid had leaked into the transmission and ruined the transmission presenting a financial burden and a huge safety issue.

I was pulling out of my garage when my check engine light came on, I took my care to a garage where they diagnosed it as a transmission problem. I took it to a transmission shop where they have found that my transmission fluid is leaking into my radiator and vice versa. They mechanic said he has seen quite a few of these, when I called Nissan to find out more I was told that there was no recall even though there are many of these Pathfinders with the same issue. It is the failure of a 400 dollar part that Nissan sent no notice to anyone for. I was told I was out of luck. I have owned 5 Nissans and because of this absolute disregard for customers will not buy another one.

As I was driving my 2007 Nissan Pathfinder (120,000 ,miles) through a busy intersection, I lost the ability to accelerate at all. After a very frightening couple of minutes I was able to steer the vehicle through and coast down a small incline to a nearby parking lot. After threedays our local mechanic determined that he was unable to fix the car, as he concluded that the ecm had failed. The vehicle was towed to the local Nissan dealership, who agreed that the problem was the ecm ($1014 repair). After three more days, they've now told us that the problem is not the ecm, but the fact that the radiator fluid has leaked into the transmission, destroying it. They are quoting a repair cost of $7500. I have been without a vehicle for over a week (renting a car became cost prohibitive), and now will spend the morning trying to find a more cost effective way to have the vehicle repaired. I've learned that this is a common issue of which Nissan is completely aware. The coolant leak/transmission failure is in fact a design defect in the vehicle. It is completely unacceptable that Nissan has not recalled these vehicles, or at the very least made the repair free for consumers regardless of vehicle mileage. I will never purchase another Nissan after this experience.

While driving on the highway, I felt my transmission seem to shift very roughly into overdrive, and usually occurred between 40 and 50 mph. Over the course of about a year, it continued the behavior off and on, until it began to do it daily and I took it to the shop. It was diagnosed as having had antifreeze leak into the transmission due to the oil cooler lines cracking, a common problem with Nissan Pathfinders, and other Nissan vehicles of my model year. There was metal in the transmission pan which signifies that a rebuild is inevitable, all due to the mixing of antifreeze in the transmission. The radiator must also be replaced due to the mixing of transmission fluid, as the mechanics found the "milky" substance, typically associated with the mixing of water and transmission fluid in the radiator. So far, I have been quoted approximately 6,300 dollars for a repair job on this vehicle.

2007 Nissan Pathfinder radiator defect causing leak of coolant into transmission fluid and resulting in transmission/radiator complete damage, undetected by dealer service for 30,000 miles. Problem detected with opening of investigation. Nissan requires CO-pay of $2,500 even though complaints occurred previous to 80k miles and when problem detected, was 414 miles over requiring a significant amount of money for a known defect.

The contact owns a 2007 Nissan Pathfinder. The contact stated that while driving approximately 45 mph, the transmission began to jerk with hesitation. The contact was able to continue driving. The vehicle was taken to a transmission shop for diagnosis, where the technician stated that radiator fluid leaked into the transmission which contributed to the failure. Also, the vehicle was taken to an authorized dealer, where they informed the contact that the transmission would need to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and was unable to provide assistance. The approximate failure mileage was 80,000.

Start having problems in mid July of 2010. Transmission was jerking in gear. Radiator broke down, allowing fluid to leak into the transmission. Vehicle is inoperable. Also been having problem with fuel gauge. Unable to get vehicle repaired, due to limited income. Vehicle became inoperable passed extended warranty.
