Transmission Fluid Leaking problems of the 2007 Nissan Xterra

The contact owns a 2007 Nissan Xterra. The contact stated that while driving 35 mph, there was an unknown pink fluid leaking from the radiator, without warning. The vehicle was towed to residence. The contact was informed by an independent mechanic that the failure was caused by fluid leaking from the radiator to the transmission. The contact called Nissan of st. Augustine (2755 us-1, st. Augustine, FL 32086, (904) 447-2960). The vehicle was not diagnosed nor repaired. The manufacturer was contacted but no further assistance was provided. The failure mileage was approximately 149,000.

Transmission has been making a loud noise, a loud "clunk" periodically when in motion and more prevalent going uphill. The mechanic stated the transmission needs replaced due to radiator fluid leaking into transmission and has ruined transmission. He stand transmission fluid is contaminated.

I was driving in an intersection when my gears slipped almost causing a multi-car collision because my car was shifting correctly. I wasn't sure what happened until it happened a couple of more times the same day. I knew immediately that something was wrong with the transmission on my automatic 2007 Nissan Xterra. I've had no issues with the transmission or car at all until then. The engine is strong and sound. Everything works except now the transmission has failed. I use this vehicle simply to drive to work and state to state highway traveling. I took it to my mechanic after the incidents and noticing a milky brown substance leaking from the radiator. Opened it up and the radiator was completely mixed with transmission fluid. Apparently, the hoses from radiator and transmission are intertwined from the factory manufacture build. This mistake is now going to cost me thousands of dollars and could have potentially costs human lives in a horrific accident! after researching online this seems to have happened to thousands of Xterra and frontier owners. These cars need to be recalled or else several highway/safety issues will occur. Imagine driving and suddenly you have no powertrain to redirect your vehicle from oncoming cars on a street or highway. Or in my case when yielding and turning in an intersection where vehicles are traveling towards you and you cannot move. Luckily some cars swerved out of the way. Also, the financial cost of the vehicle is absurd for something that could have been avoided from the manufacturing build altogether.

(jl no dealer info, failure mileage was not included) tl the contact owns a 2007 Nissan Xterra. While driving various speeds, the contact experienced a bumpy ride. In addition, the vehicle would decelerate, the odometer would decrease, and the vehicle stalled. There were no warning indicators illuminated. The failure occurred three separate times. An independent mechanic diagnosed that transmission fluid was leaking into the radiator. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 126,000.

My vehicle lost power while I was driving. The transmission was damaged as a result of a faulty radiator issue allowing fluid to leak into and destroy the transmission. Nissan will not do anything to help repair.

Another frustrated 2007 Nissan Xterra owner who¿s radiator and transmission had to be replaced. Three weeks ago noticed some tranny slippage while driving (normally 80 miles a day, 5 days a week and all on highways), checked fluid, no problem, no leaks or nothing, though maybe just drain and change fluids. Then 1 week ago today, I was at a stop light when my temperature gauge spiked to hot and radiator started to smoke, started to move on the green light to pull over to side of road from a four lane highway and I was in the second lane over, car started to chug and barely made it to the side of road before it quit, then a gray colored fluid started draining out of my radiator overflow all over the ground. Had to make the call to a shop and they knew exactly what the problem was before they came and got it. The car got towed to shop where they quoted me $5590 for towing, new radiator and rebuilt tranny. Wtf¿.

Nissan transmission fluid/radiator coolant leak issue: rough automatic transmission behavior noticed during stop and go city driving. Check engine light came on. Repair shop diagnosed check engine light code as transmission torque issue, pointing to transmission fluid. Repair shop found leak in coolant radiator servicing the transmission fluid, resulting in water/glycol intrusion into the transmission fluid. Radiator, and coolant fluid replaced, as well as transmission fluid flushed/replaced. A few days later, transmission slippage was felt and the check engine light appeared again. Expecting transmission has been compromised due to prior, defective radiator.

The contact owns a 2007 Nissan Xterra. The contact stated that the transmission fluid leaked onto the radiator and ruined the transmission. There was no warning indicator. The vehicle was not diagnosed. The manufacturer was not made aware of the failure. The failure mileage was 123,000.

When I am drivinging at a slow speed , my transmission makes a noise and then feels like it's going to die, now I have noticed that there is fluid leaking from my radiator. When I researched the issue I was having and realizised this is a recurring problem that is being reported by many Nissan Xterra owners and that nission has been aware of this issue since 2007 , when I originally purchased my Xterra . Now that I understand what the issue is , the radiator is leaking fluid in to my transmission and is destroying the transmission and radiator . In doing research on the problem I was having , and what happens when this occurs , I'm frightened to even drive my Xterra at this point . Considering that Nissan takes no responsibility in what should clearly be a recall , I'm stuck with a car that I've just recently paid off , that I am afraid to drive and do not have $4,700 to have the radios and transmission replaced . There was no warning when this happened at all . I have always maintained my Nissan and thought I had made a well informed decision in my purchase . I will never do business with this company again . I'm so disappointed in the situation Nissan has put myself and apparently many , many others in . No way to do business .

Eight hours from home, the truck would not start and had to be towed. Initial local garage could not diagnose the problem. Chris myers Nissan in daphne, al, was the closest dealer. They were called and diagnosed the problem over the phone. It is a known defect in these vehicles that allows the radiator to fail and leak radiator fluid into the transmission, destroying it and the module. This cost $5,225 to repair in addition to the tow and driving back another 8 hours to retrieve the vehicle. Nissan na was completely unhelpful. Despite this known defect, they refused to assist with any cost. They previously agreed to a court order to repair these issues but only under 80,000 miles. This is a known issue with these vehicles that is certain to occur in all of them. This definitely should be a recall and they are shirking their duty with this defective system. Their should be no mileage limit as they know this will eventually occur with these vehicles.

This complaint is in reference to a 2007 Nissan Xterra off road 4x4 with180,900 miles. The transmission began to spontaneously downshift to low gears while moving at speeds above 25 mile per hour. At one point, the transmission seized and locked up while traveling at 45 miles per hour, which resulted in a sudden stop in the midst of the traffic flow on a two lane road. I took the vehicle to the Nissan dealer for service immediately. Inspection revealed coolant had leaked into the transmission via a leaking transmission cooler assembly integrated into the main engine radiator. The transmission sustained substantial internal damage from the coolant mixing with transmission fluid and circulating through the transmission. The transmission and engine radiator had to be replaced in order to make the vehicle roadworthy again. Total cost of the repair with taxes was $4800. 00. Nissan service manager and techs at dealership indicated this is a common problem for the Xterra and frontier model vehicles, yet no proactive action was taken during previous service appointments at 30,000 mile service intervals, routine maintenance appointments, and during yearly state vehicle inspections conducted at the same Nissan dealership.

5 months ago the transmission fluid leaked into the radiator causing antifreeze and transmission fluid to mix now the transmission has gone out because of this caused be to be stuck on the road I now need a new transmission.

A hesitation in the vehicle's acceleration began occurring frequently upon depressing the accelerator after a full stop at a stop sign or red light, but not at any other time in driving the vehicle. The problem was first noted when departing the dealership after which a new timing chain had been replaced. When reviewed by the dealership upon return to the service area (another appointment had been made at later time), a loss of over one quart of transmission fluid was detected (over what time period was unclear), but no known source of external leakage was found. This led to the conclusion that internal leakage was very likely occurring. Due to the many instances of radiator cracks and toxic mixing of fluids among similar year models (mid-2000 model years of Nissan Xterra), the dealership recommended that the radiator be replaced and the transmission thoroughly flushed, which might prevent the transmission from requiring a complete overhaul in the future - although there are no guarantees. This work was completed for a total of $1500 including discount; the incident occurred well after the extended warranty provided by the manufacturer for resolving issues that had been experienced by others, hence the dealership's charges. A request was nonetheless made to get reimbursed by the manufacturer (Nissan), currently under review. It is possible that this issue was dealt with at a very early stage and might therefore result in a lower probability of transmission problems in the future, which could cost several thousand dollars ($6-7,000 or more). Other drivers/owners have typically experienced more severe issues, such as shaking/stalling vehicles and/or illuminated dashboard lights indicating engine problems.

Tl- the contact owns a 2007 Nissan Xterra. The contact stated that there was a transmission failure and that there was a component that fractured with no warning associated with fluid leaking from the radiator into the transmission. The vehicle was taken to an authorized dealer who diagnosed that the transmission and the radiator needed to be replaced due to a crack in the atf line that flows through the engine coolant chamber into the radiator. The vehicle was not repaired. The contact was not included in NHTSA action number: dp12004 (power train) the manufacturer was notified of the failure. The approximate failure mileage was not available. Dyd.

Vehicle abruptly stalled without warning when making a left hand turn. Oncoming traffic was forced to stop. A serious, possibly deadly, accident could have occurred if the oncoming traffic had not stopped. The vehicle had shuddering during acceleration prior to this incident but had never given any indication it would stall unexpectedly. The vehicle had been maintained by Nissan and no issues were brought to my attention during this service. When Nissan diagnosed the vehicle they found that the transmission cooler had leaked and allowed transmission fluid and engine coolant to mix. This lead to transmission damage and unsafe, unexpected failure of the transmission. Nissan also said they had known about this common failure for many years. I was never informed of this dangerous design flaw.

On 3/28/15, parking my 2007 Nissan Xterra (126,0000 miles) in tampa, FL. Before I had the car in "park", there was a loud noise, the engine started smoking and a lot of purple/green/gray fluid leaked out from the bottom of my car. Afraid to move the car, aaa towed it to the Nissan dealership in tampa. When the tow truck driver arrived and saw the color of the fluids, he quickly determined that my car had leaked both transmission and radiator fluid. He said he heard that this was a problem with Nissan Xterras. I was shocked! since purchasing new in December 2006, I have always taken my car to Nissan for all service. Other than a few oil changes, all service has been performed by Nissan dealerships and their certified technicians. Just prior to this incident, my car had been shaking. I had been to Nissan with this complaint in the past, but after repairs were made it seemed to go away. At no time was a transmission problem mentioned as a possibility. I have lived in different areas in florida and used only Nissan dealerships for service and repair, willing to pay more for repairs than an independent repair shops, that Nissan dealerships and service would know my vehicle best & be proactive, alerting to any potential future problems, I felt protected. The last major repair was in July 2014, at 113,000 miles at autonation Nissan, delray, FL. Complaint was severe shaking, and stumbling when accelerating. Repairs were over $1,000; a transmission issue was never mentioned, even after further repairs were needed. I was never informed of transmission problems with Xterras until Saturday at the dealer in tampa, who said he alerts all Xterra owners to be proactive with radiator replacement. After the comment I did research online. I was unaware of the class action suit settled with Nissan; I was never notified of a problem history with Nissan Xterra transmissions and radiators.

The radiator fluid leaked into the transmission and ruined the transmission and valve body assembly. The car will not run and stalled out in an intersection.

My 2007 Nissan Xterra came on with a check engine light and over drive indicator light stayed on. Obdii code for check engine light was p0700 transmission control system tcs malfunction. The transmission would no longer use 1st, 2nd, or 3rd gear. Reverse, neutral, and drive could still be selected but when in drive it was in 4th gear only. Took it to the Nissan dealership and they told me that coolant from the radiator was leaking into the transmission and this was a common issue that the service department had seen before many times now. They informed me that I was 1500 miles over warranty and that I would have to contact Nissan customer care. That is when I discovered that there was a class action lawsuit for this problem against Nissan because this was a known defect for 2005-2010 Xterras and they wouldn't do a recall. Now Nissan is telling me there is nothing they can do for me and they will charge me $7500 for parts and labor to replace the transmission, radiator, lines and fluid. That is outrageous as my 2007 Xterra only values at $8000. I was never notified when I bought this SUV in August of 2012 that it was part of a class action lawsuit and in the 2 years I have owned I have never been notified by Nissan of a settlement that could have alerted me to have this checked sooner before transmission failure happened. I also wouldn't have bought the car if I had known there was a known issue with the radiator leaking into the transmission that Nissan is not willing to recall for. Now I am trapped with a loan on a lemon I cant drive and cant afford to fix.

The radiator used in my 2007 nisan Xterra is a faulty product which caused a leak of the radiator fluid into the transmission fluid system. When the transmission heats up during longer periods of driving, the radiator fluid also heats up and effectively ruins the internal transmission parts. This has caused several issues in the shifting of the vehicle, and often times in very dangerous situations where acceleration is key to avoiding accidents.

A defect caused a crack in the transmission radiator which leaked fluid into the transmission causing unexpected catastrophic transmission failure.

The radiator leaked fluid into the transmission and cause a complete and total loss of both. A lawsuit was filed and settled by Nissan without them taking any responsibility for their faulty design. I guess this won't get noticed until people start dying from Nissan's defective design. When that does happen, Nissan will just payoff the families so this whole issue just goes away!.

Problem with radiator fluid leaking into the transmission, which has now damaged the transmission. Since Nissan won't do the right thing and we're beyond the 80,000 miles, we're stuck paying for a new radiator and transmission. Instead of getting away with doing nothing except for extending the warrenty, Nissan should have been required to notify all affected people regarding the exact problem and issued a recall and pay for a new radiator. This obviously is still an issue for alot people and probably many, many more in the future, long after the so-called proposed settlement. Too the NHTSA! please investigate and require Nissan do the right thing!.

I have a 2007 Nissan Xterra which started to "stutter" and hesitate when pressing the gas. The car almost felt like it was shutting off while on I-4 highway. The shuts down and wont start. I had the car checking and found out that there was a crack in my radiator and that the fluid had leaked over into the transmission. I had the radiator replaced, a few months later, transmission is still not working. I took the car to Nissan, they told me I would have to replace the whole transmission which would run about $5200. I called the Nissan headquarters and was told that there was nothing they could do because my truck was at 109,000 miles.

Our 2007 Nissan Xterra, purchased brand new, began to overheat. Upon checking the fluids I noticed the coolant level was dangerously low. I was certainly puzzled where the fluid had gone because there has never been any visible leaks or any warning lights or any other symptom to draw my attention. I began to look into the situation because I was puzzled and quickly learned of the massive number of Nissan owners experiencing the same problem. Sadly, I was now one of those victims. Yes, the coolant had contaminated the transmission fluid via the faulty transmission cooler. There is a class action lawsuit that I am sure you are aware of but I was unaware of. I do not recall any contact notifying me of a class action lawsuit and the potential damage. I had no reason for worry because my vehicle had not given me any trouble signs and the fluids have always checked normal during normal service checks. Like many, I cannot afford to shell out the dollars that this negligence on Nissan corporation behalf has caused. I encourage you to please force Nissan corporation to issue a recall requiring them to make all the appropriate repairs for these damages. Please, do not put a cap on the mileage or set the mileage relatively high if you must. My vehicle has only 89,000 miles and only gave signs of damage less than 500 miles ago.

Sudden loud noises/banging while driving. Pulled over, had vehicle towed to mechanic. Radiator found to be cracked. Radiator fluid leaked into and contaminated transmission causing sudden transmission failure. Learned Nissan was/is aware of this problem and has not notified anyone of preventative measures to prevent failure of transmission. "extended warranty" resulting from class action lawsuit requires $3000 copy for vehicles with 90,000-100,000 miles. My mechanic says this is a joke because radiators not cracking until at least this time. Now I have to pay $3000 I don't have to repair the transmission which I could have saved had I been notified to replace the radiator. I will not ever purchase a Nissan again.

I was driving my car and it shifted into 4 wheel drive at a red light with no prompting. The car then was immediately pulled over and turned off. The car would not start following it being turned off. It was then towed to a mechanic shop where they discovered that the radiator had leaked fluid into the transmission, causing the coolant to mix with the transmission fluid and completely disabling the car.

The contact owns a 2007 Nissan Xterra. The contact stated that while driving 68 mph the vehicle stalled. The vehicle was towed to an independent mechanic for diagnosis. The contact was informed that radiator fluid had leaked into the transmission and both the transmission and the radiator would need to be replaced. The manufacturer was notified but stated that due to the mileage of the vehicle, they would not assist in the repair. The vehicle was not repaired. The failure and current mileage was 113,000. . . Updated 04/18/13.

Last month the car seemed to start slipping gears when I got up to around 40 miles per hour. It was sporadic and once I let me foot off the gas for a second it seemed to clear and be ok. I started to see a slow leak of what I thought was oil in the garage where I parked the yesterday. When I mentioned the leak to a buddy and also told him that my heater was not working, he said we should check the coolant in the radiator. When we opened the radiator cap, there was a slimy brownish sludge all over the bottom of the cap. That afternoon, I brought the car to the mechanic across the street and he said that I had a radiator failure of some that has caused radiator fluid to get into the transmission. This is where the brown sludge has come from. He said the car needed a new radiator and the transmission had to be flushed, dropped, and serviced and it would not guarantee that the transmission needed to be replaced sometime soon after. The entire thing he quoted me as costing $3k. I called my Nissan dealer where I had purchased the car from new in April 2007 and the gentleman in the service department seemed quite aware of the issue and informed me that the radiator replacement is under and extended warranty from Nissan, but I would still be out of pocket for at least a $2500 CO-pay for the replacement of the transmission.

Started smelling a burning smell. Noticed a fluid leaking under the car. Dealership said transmission needed to be replaced but didn't give any further details. Topped off transmission fluid since it was low. 30 miles later, while doing 65 mph on the freeway in traffic, the car suddenly slipped out of gear and slowed drastically almost causing the car behind me to rear end me. I slowed and it popped back into gear. I got it off the freeway and was then able to barely get it into a parking lot. I had it towed to a repair shop and was informed that fluid from the radiator was leaking into the transmission which damaged the transmission. I went back to the Nissan dealer and they apologized for not providing me all of the details and stated that Nissan is aware of the "design flaw in the radiator" but is not covering any of the repairs.
