Transmission Fluid Leaking problems of the 2006 Nissan Xterra

Radiator failed, coolant mixed/leaked into the transmission fluid and caused the transmission to fail. Gas gauge quit working properly.

I have an Nissan Xterra with a bad radiator , it is leaking transmission fluid, according to the internet Nissan has known about this defect for over 13 years and has never issued a recall, I think it needs to recalled due to bad radiators that leak transmission fluid and antifreeze together, Nissan is aware of the defect but has done nothing to fix or adress the issues all Nissan Xterra owners had due to the defect, including replacement of transmissions and radiators and other parts related to the defect, it is a safety issue if the transmission locks up on the roadway at any speed limit. .

Tl the contact owns a 2006 Nissan Xterra. While driving approximately 50 mph, the radiator fractured and there was a transmission fluid leak. The contact, an independent mechanic, diagnosed that the oil cooler within the radiator was faulty. A dealer was not made aware of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 77,000.

Leaking coolant is mixing with transmission fluid through the cooler lines to create a toxic hell stew that irreversibly damages everything around it.

I am the very unfortunate owner of a 2006 Xterra, that is experiencing the infamous radiator leaking coolant fluid into the transmission. I have a 2006 Nissan Xterra automatic 4wd; purchased in 2009 certified pre-owned w/ 46k miles on it. Now it has 137k on it and I unfortunately experienced the infamous "strawberry milkshake of death" where due to a radiator default it leaks coolant fluid into the transmission causing irreversible damage 2 days ago on may 6th 2017. Right now the radiator is dead as well as the thermostat; a mechanic shop inspected the vehicule as I pulled over to their place when I experienced the issue and stopped driving immediately. I reached out to Nissan consumer affair and; to just be able to go forward I must have the car tow to the closest dealership as it is the procedure and they can't determinate anything before car got inspected by official Nissan service dpt. Changing the radiator and the transmission will be pay out of my pocket unfortunately at this stage. I am out the mileage settled after the class action suit Nissan got hit for this well documented issue. I am just another victim of what should have been a national recall from Nissan.

My 2006 Nissan Xterra began shuddering as if the car was riding on rumble strips, while I was trying to maintain speed. When the od is off it does not shudder/rumble. After an inspection and research we determined that coolant was leaking into the transmission fluid and causing the car to shudder. We have taken great care of our car and this is a manufacturer defect in the radiator and it should not be paid for by the consumers!.

The contact owns a 2006 Nissan Xterra. The contact stated that the vehicle was taken to the dealer where it was diagnosed that the radiator leaked fluid onto the transmission and both components needed to be replaced. There were no warning indicators. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was 112,000.

I am writing this in regard to the radiator cracking and leaking coolant into the transmission fluid. This problem completely ruins transmissions and there is no way to tell the problem is occuring. I have had the vehicle inspected regularly and maintained to all manufacturer specifications. I received zero notification from Nissan about this issue. This is my primary vehicle I use to transport my child. I was left stranded on the side of a back road in extreme heat due to this defect. The cost of repairing this issue is well over the worth of the vehicle itself.

I was on my way back from the the mall when I heard my fan/belt start to squeal. Not thinking anything of it I keeped on driving next thing I know I'm pressing harder on my gas peddle just to go faster. My rpms where going to high and I was only going 65. I was on the high when this happen so I didn't notice till I had to go up a bridge and that's when I really notice my engine struggling to get power, it sounded like it was doing a lot when it really wasn't. I knew I had to go to the machanic to get it looked at they told me it was a lose bolt. Next thing ik I'm driving home and my car was doing the same thing again but this time it wasn't going into gear in drive, so I tried 3 gear still nothing so I went to 2 and it stuck. I parked it on a side street in ocean city and called trip a and had it towed to Nissan of atlantic city to see what was wrong. Couple days later they called and told me my raidiator fluid leaked into my transmission and messed all the gears up. After hearing that I looked up that problem on Xterras apparently this is a pretty common accurance on them. I was not notified of such problems by the dealer and apparently Nissan want renberrse me so I'm out 7,500 because my Nissan is sitting in my back yard.

Radiator coolant leaked into transmission fluid and ruined the transmission. Known issue.

Defective radiator leaked engine coolant into automatic transmission fluid (atf), causing cross-contamination of fluids that will ruin the re5r05a transmission. The engine coolant water contamination can short-circuit the low current electronic computer located on the valve body. This transmission was used in Xterra; frontier; pathfinder and armada vehicles manufactured between 2005 and 2010. Fixing the radiator and replacing the contaminated fluid with fresh fluid does not alleviate the problem, as the transmission computer has been permanently damaged. The only way to fix a damaged transmission computer is to replace it with a new one, and they are only available from Nissan as part of a new valve body assembly. . Read more...

This problem has been happing to my vehicle for awhile but I was unaware until last week. My truck was overheating and the antifreeze had a white substance in it. My mechanic told me it was mixed with transmission fluid. The radiator cracked and the trans cooler which is inside leaked. The two fluids mixed and has caused transmission problems. My radiator has to be replaced and the trans will be flushed several times. The extent of damage to the trans is undetermined at this time as it is still in the shop. I researched this problem and found it to be a very common problem with Nissan Xterras. The symptom's of others vehicles are exactly the same as mine. Nissan has had a very poor settlement in a class action suit but it is very poor. This shows that they are aware of the poor engineering design and/or parts. This problem is leaving people with several thousand dollars in repairs ($3800 and up) for a problem that Nissan is aware of. Even though you have maintained your vehicle routinely this problem will still occur due to Nissans poor design and parts. This problem should be covered under a recall and if an owner has fixed the problem they should be reimbursed for their expense to repair the problem.

When my Xterra was idling in park or at a stop light, the car was overheating. Also while accelerating, the car was shuddering when changing gears. Upon taking the vehicle to a repair garage, I was informed that this particular model Nissan is notorious for faulty radiators being installed which caused coolant fluid to leak / mix in with transmission fluid, thus damaging the transmission, possibly to the point of having to be replaced as well as the radiator. My car is sitting at a garage now waiting for the radiator to be replaced and try to run the vehicle to see how bad the damage now is to the transmission.

Radiator fluid leaked into the transmission causing the tranmission to fail and ruined the radiator. My Xterra had 106,000 miles on it at the time of the failure. The cost to replace the transmission and radiator was nearly $5,000. 00. The cause of the failure is the same factory defect mentioned in previous complaints.

The contact owns a 2006 Nissan Xterra. The contact stated that the gear would not shift into reverse. An independent mechanic noticed that the transmission fluid was mixing with the coolant and the coolant was leaking into the transmission. The contact was informed that the transmission and radiator needed to be replaced. The vehicle was not repaired and the manufacturer was notified. The approximate failure mileage was 169,000.

Well I was driving along and the vehicle started chugging and then it stopped moving, when I had a transmission shop look at it they told me the radiator cracked and leaked fluid into the trans and destroyed the trans, now it is going to be replaced or rebuilt. I cannot afford this but need to get it fixed since I borrowed money to buy it. I was told by the trans shop that this was a common problem and it is not supposed to happen since the trans fluid lines and radiator fluid do not come into direct contact with each other, but is a defective radiator and design that caused this problem.

Transmission jerks and shudders at speeds around 40-60 mph when it shifts into overdrive. This occurs under light engine loading and while traveling up hill. Also, have noticed it at lower speeds lately. During the winter, the vehicle failed to heat properly; adding more coolant alleviated this problem, but only for a short period of time. After inspection, it is found that engine coolant is leaking into the transmission cooler and transmission fluid, causing both the engine to run low on coolant (and cause a no-heat situation) and is most likely causing the transmission to fail.

I have warranty extension notices sent out by Nissan. They are for a leak in the radiator they may go into the transmission. . My radiator was replaced because the dealer said it had a leak. There was no fluid in my garage or driveway. . Now my transmission had to be replaced 76993 miles. After dealing with customer service they told me it was not a related problem. . There has been a class action in against Nissan for this problem. The cost was $4500. 00. If you need any other question answered please call me at 716-866-5981. . I am looking for reimbursment for the cost of tranny repair. . All work was done by mike barney Nissan 3676 sheridan drive amherst,NY 14226.

Vehicle did not shift smoothly and was overheating. Mechanic determined that the transmission fluid and engine coolant were intermixed due to a leak in the transmission line in the radiator. Both radiator and transmission must be replaced due to the fluid mixing.

Transmission failure on highway. Car stopped working going 65 mph. Radiator fluid leaked into transmission.

We noticed a higher pitch noise from the vehicle in August 2013 during all running times (cold start, warm running, etc) in my pregnant wife's car with about 90,000 miles on vehicles (inspected fluids, belts, and engine area without notice to any issues- assumed it was the sub-freezing temperatures ~5-f). Regular maintenance has bee conducted on the vehicle since purchase (original owners), had the heater core repaired and vehicle inspected at Nissan dealer in texas in 2011 without knowledge of transmission problems (heater core is leaking again 2yrs later). There was no impact to driving at the time. Figured it would only need a tune-up back from colorado to georgia before finally getting it checked and was diagnosed with transmission and engine coolant cross contamination requiring $4,500+ in repairs (now at 103,000 miles -Dec 2013). Automatic transmission was completely flooded/contaminated with engine coolant ruining the internal components. Mechanics stated that is a known problem with Nissan Xterra's and other models, that they didn't know how our transmission didn't already fail with the amount of exposure, and it would be a short time before the transmission becomes completely in-operational. After some research, we have discovered that many people have had a similar issue across Nissan models, and we do not qualify for the class action law suit (which you had to claim by Jun 2013 and have document/diagnosed transmission contamination >100,000 miles). Nissan should be required to recall/fix their design flaw and safety hazards for protection of the consumer!.

On December 06, 2013, while merging onto the highway, my gray in color, 2006 Nissan Xterra, completely lost all motive power & failed to shift gears, simply revving out in 2nd gear. It should be noted, my 2006 Nissan Xterra is the 4x4, automatic transmission & had around 99,950 miles at the time. The incident put myself, my wife, and my eight month old baby girl in danger due to the fact we had no where to exit the highway & were quickly slowing down in traffic. This incident almost caused an accident because I was unable to accelerate to get out of the way of the faster highway traffic. It has since come to my attention that Nissan is aware of this issue and that it is caused by the radiator leaking coolant into the transmission causing the transmission fluid to mix with the radiator fluid, effectively destroying the transmission. I was able to slowly work the rpms up & get the transmission to shift up a few gears so we could make it off the highway. I then contacted my local Nissan dealer who advised that Nissan was aware of the issues and have extended the warranty to 100,000 mi. He informed me that to replace the transmission & the radiator it would cost approximately $7000, however, if I was under 100,000 mi, I would only have to pay a $3,000 deductible. Because I had passed the 100,000 mile mark by driving my vehicle back home, I was no longer eligible for this extended warranty. I've owned my Nissan Xterra for over 6 years & have made sure to stay current on all the routine maintenance. The fact that Nissan is not only aware of these issues (which have allegedly affected thousands of Nissan owners), but also that they have failed to take any corrective action, is simply unacceptable & also downright dangerous. It is one thing for Nissan to not stand behind their product, but it is wrong for them to knowingly allow their product to put people's lives in danger.

Transmission failed due to well known issue with 2005-2010 Nissan SUV/truck transmissions. Coolant leaked into transmission fluid through coolant line causing catastrophic failure. Dealer quoted $7000 to replace transmission.

Tramsmission was beginning to make noise and shifting roughly. I took it to the Nissan dealer and they said the radiator was leaking into the transmission fluid causing damage to the transmission. They said it was not covered under warranty and it cost me over $3500 to repair.

This 2006 Nissan Xterra problem has caused problems with stability of the vehicle, lurches in acceleration, near-stalls, and uncertainty about reliability of vehicle in taking trips. The problems continues to get worse and we have determined that it is caused by engine coolant leaking into the transmission and vice versa. There is very visible evidence of the coolant being in the transmission and transmission fluid in the radiator. I have checked both of these and there is no mistaking it. This problem has caused me to not be able to take two trips because of being afraid of the transmission completely failing and leaving me and my family stranded in a remote area during the trip, not to mention my everyday driving that is required.

Cpsc: i1340159a. Nissan Xterra. Consumer stated the problem with this vehicle, is radiator fluid leaking into the transmission.

I was driving 35 mph on a busy street when my vehicle would not accelerate. I towed my car to Nissan dealer and was told my trans was no good and it would cost 6,000 to 10,000 to fix. I contacted Nissans consumer affairs and they said I did not qualify for any warranties. Nissan told me there was no radiator fluid in my transmission which seems to be a common complaint. I towed my car for a second opinion and was told my trans does have radiator fluid in it and it also flooded my computer in the trans. Why did Nissan lie to me? I found that Nissan did extend the warranty on the radiators and that an e-mail did go out to Nissan owners stating they would also cover the trans if caused by radiator leakage to 80,000 miles but Nissan told me I don't qualify because I am a second owner? still waiting on a response from Nissan. This has caused a great hardship on me.

Radiator fluid leaked into my transmission. This caused an entire shutdown of my transmission. I was told by Nissan that it would take up to $5,000 to repair. The radiator fluid leaked due to a defect that Nissan could have easily recalled and avoided. I have conducted research and found that thousands of other Nissan owners have experienced the same problem and Nissan is not willing to do anything about it. I was told that I would be responsible for the cost even though this could have been easily avoided by Nissan manufacturers.

Tl- the contact owns a 2006 Nissan Xterra. The contact stated that while driving 35 mph, the vehicle stalled without warning and fluid was shooting out from under the hood. The vehicle was towed to a dealer who diagnosed that there was a coolant leakage which sipped into the transmission. The vehicle was not repaired. The manufacturer was made aware of the failure who did not offer any assistance since the vehicle was no longer under warranty. The failure mileage was 104,000. Pmb.

Transmission failure due to issue with radiator defect. Radiator fluid leaked into transmission eventually caused catastrophic damage to transmission parts. Power train failure occurred while on the freeway almost 30 miles from home. My personal safety was definitely in peril and only due to skill and luck was an accident averted.

I am the owner of a Nissan Xterra I purchased back in Feb 2006. I was happy to make my last finance payment in February. Last week while driving home from work my car's check engine light turned on then started to overheat. Later I found out my car was leaking a white substance which was difficult to get off my driveway. I was surprised since I regularly keep up with the maint and never had any problems in the past. I had my car towed to Nissan in to find out what was wrong. The dealer informed me that the car had a leak and the coolant and transmission fluid began to mix to create the white substance which ruined my transmission. After doing some research online, I was disappointed to find out this was a common issue with the Xterras and that Nissan made a design change to fix it in later Xterra models. Told me that I needed to replace my transmission, radiator, upper/lower radiator hose. Their initial estimate to fix my car was $8500. After I heard the number, I priced each of the parts out online for approx $1500. Provided a new estimate for $5,500. Because this was a known issue, I would have thought Nissan would have done the right thing to fix it as part of a recall. When a person buys a car there is an expectation the car will last more than 5 years. It is unacceptable the extended warranty once you exceed 85,000 miles is no longer valid. Because of the experience with the dealer and the quality of cars you provide, I will never purchase a Nissan again. In addition, I am planning to share my Nissan experience with online forums and friends about the quality of service Nissan does not provide or stand by their products. If you have any questions please feel free to contact me. Ex-Nissan owner - information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

We have an 2006 Nissan Xterra and the radiator leaked into the transmission and caused a cross contamination. We had to replace the radiator and have the transmission rebuilt. We participated in the Nissan class action lawsuit, but unfortunately we received a denial letter in the mail earlier this week because we were over 100,000 miles. I am highly disappointed with Nissan for being so greedy and not taking responsibility over this issue. This problem happened to occur the winter of 2011 when I would go out to start the car and it would blow cold air and never heat up unless the car was running. If I was to sit at red lights the car would blow cold air again. That spring I noticed the car jerking and driving a little rough but didn't think much about it because we had just replaced the universal c joint back that prior fall. The summer of 2011 and at first I noticed the rpm's revving up but the car wouldn't go anywhere. Then the air went out and would cool down the car. Meanwhile I am driving my kids around in a car with no ac in 100 summer heat and humidity. Eventually the car got so bad it wouldn't run. It would rev up but go no where. I finally took it into a shop when I noticed it leaking a reddish, brown/green fluid. Come to find out there was cross contamination between the radiator and the transmission. I had been driving months with this car like this it really messed up my Xterra. It cost me $4500 to fix this issue on top of many inconveniences. I't super disappointed in Nissan for not recalling this faulty part they knew about. Apparently a letter was sent out asking customers to bring the cars in to be checked. We never received this letter. All I want is Nissan to fess up and pay hard working people back the money they owe them. My Xterra was paid off and I had to sink $4500 into a 6 year old car. Nissan has lost a customer for life. Ill never buy another.

I have a 2006 Nissan Xterra and noticed it was driving rough off and on. I took it into the dealership as there was a recall on the ecm relay and asked them to check the rough driving. I was called and advised that my radiator broke which caused fluid to leak into my transmission and would need to replace both. I was quoted $9200. 00 which is unacceptable. I use my truck strictly for communting, dont even use 4wd. The truck isnt even paid off yet. There is no recall on this, yet as I do research I have found that this is a common problem, yet Nissan is doing nothing about it. I called aamco and was advised it would cost $2800-3200 for them to fix and that they see this with Nissans way too frequently. My personal mechanice advised he can fix it for around that same price as well. I depend on this vehicle for getting to work and safely getting my children to school. What a let down for such an expensive purchase.

The contact owns a 2006 Nissan Xterra. The contact stated when driving at various speeds, the vehicle would exhibit abnormally, violent vibrations. The vibrations were more intense when the vehicle would shift into third gear. The contact further examined the vehicle and found transmission fluid leaking into the coolant system and coolant leaking into the transmission system. The dealer advised that the failure was common in his model vehicle yet there were no recalls. The vehicle was not repaired. The failure and current mileages were 73,000.

July 2006 I purchased a new Nissan Xterra. October 2008 at approx. 58,000 miles the transmission failed. The transmission "slipped" as I made a left turn. The vehicle momentarily stopped in front of on coming traffic. Traffic stopped for me. At that time the vehicle moved forward. I initially thought that this was an isolated incident but over the next few days the problem worsened. On October 30th I took the vehicle to ricart Nissan. An initial check showed a foreign substance in the transmission fluid, the service person accused me of putting oil in the transmission and stated that Nissan would send the fluid to a laboratory for testing. Approx 6 days later I received a call from the dealership stating Nissan would replace the transmission free of charge. At 60,000 miles or a month or so later my vehicle warranty expired. The vehicle never really ran correctly after that; heavy shifting, vehicle would not warm up when stationary. I made several follow up calls to the dealership but each time I was advised that vehicle was out of warranty, or over 60,000 miles. At that point I just dealt with the rough running rough shifting vehicle. Move ahead to may 2014. Once again the vehicle's transmission slipped while turning almost causing me to have an accident. At this point I began researching my vehicle and found out that transmission problems, more specifically coolant leaking into the transmission causing failure was an on going problem, I had the vehicle inspected at pickerington ohio goodyear. Coolant was present in the transmission. At that time I notified my dealership and Nissan of my issue. Nissan stated that due to the vehicle age (175,000 miles) they could not assist me; Nissan reference number #14366908. I believe this is just as much a safety issue as a mechanical issue. If the transmission fails when turning in front of traffic an accident could take place.
