Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2005-2007 Xterra appears to have a widespread defect where coolant leaks into the transmission, causing transmission failure around 90,000 miles. Repair costs are typically upwards of $3,500.

The same defect exists in the Pathfinder & Frontier as well. And according to the New York Times & a class action lawsuit, the defect actually extends through 2010 model year. More info here.

Transmission locked up on highway. Evidently engine coolant had gotten into the transmission by way of failure of the radiator. Could have been killed...

Nissan's 2005 Xterra has a major flaw in its cooling system and transmission. Apparently the coolant in the radiator leaks into the transmission causing the transmission to fail. This is very expensive as the radiator and the transmission have to be replaced. Flushing the system is not enough. This should have been recalled and repaired by Nissan before the problem became costly. Apparently Nissan has known about this for some time. This is disgraceful.

I've noticed recently that my Xterra started shuddering while cruising at highway speeds, and has been shaking while shifting between gears. Additionally, there was a specific occasion where my vehicle stopped accelerating while merging onto the highway. When I took it to a local Nissan dealership for to fix a separate recall notice, I was told that my transmission fluid had mixed with my coolant, which meant that I would need to replace both my transmission and radiator.

Total transmission failure after engine coolant floods transmission, causing vehicle to lurch and stop. Incurred repair costs at dealership of $5,968.89. Nissan is aware of this problem on 2005 Xterras, but failed to inform owners to replace faulty radiators which causes the transmission failure. Nissan secretly extended the power train warranty to 80,000 miles because of this problem (owners not informed), but the transmission failure associated with this issue does not occur until after 80,000 miles. One website,, as 23 pages of complaints from 2005 Xterra owners documenting this issue. Ref: refuses to reimburse owners for the repairs. The Nissan Consumer Affairs file no. For my complaint is [xxx]. please help. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

There was a loud rumble and jerking while driving at 35mph. Fluid was leaking badly also. I took the car to Nissan on on April 21, 2008. They said they could not duplicate the problem. Again, the car started jerking and making loud rumbles. I took it back to Nissan and they said the U joints were bad and replaced them. As soon as I pulled out of their parking area, the car did the same thing. So, I took it back again. This time, they told me that the radiator was coming apart and leaking antifreeze into transmission. They charged me $1285.89 to replace the radiator and flush the transmission. It is now 2012 and the car is doing the same thing again. The problem was never fixed properly to begin with. I need a new transmission at a high price. Anyone reading this should phone me at so that we can start a class action law suit against Nissan. Lets inform everyone who has had this problem. From what I have been reading, thousands of people have had the same problem. This is a safety issue as well as a costly problem.

We have a 2005 Nissan Xterra that we had to have a transmission replaced on in 2007 because radiator coolant leaked into the transmission. Again, the same thing has happened. Recall these cars, please. They are dangerous and this repair is very expensive. I had read the complaint history and I am not the only one with this problem.

While driving, the engine cuts off without warning causing all systems to shut down, including brake assist and power steering causing a near collision twice, once while navigating a curve at low speed with a ditch on the right side and once while navigating a curve at higher speed and nearly coasting into oncoming traffic. The issue is due to a known defect in the radiator causing coolant to spill into the transmission. This is a major safety concern that appears in vehicles without warning in any circumstance at any speed. Please initiate a recall asap for our safety!

The contact owns a 2005 Nissan Xterra. The contact stated that he heard knocking coming from under the hood while driving approximately 30 mph. The contact also stated that the temperature gauge would display that the vehicle was overheating. The vehicle was taken to an authorized dealer, but they were unable to diagnose a failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 80,000.

Vehicle failed during operation without warning secondary to faulty original radiator which leaked coolant into the transmission. Transmission and radiator destroyed and require replacing. Despite extensive documentation of this problem on consumer websites and a class action lawsuit, Nissan America and dealership denied any knowledge of this problem and did not accept any financial responsibility. Total repairs estimated at $5,000. Notifying consumer of and/or replacing faulty radiator could prevent a costly destroyed transmission.

  • 80,000 miles
My husband and I purchased our 2005 Nissan Xterra, 17 miles young. Exactly one month after we purchased, the rear differential went out and was covered under warranty. No problems for a few years, until we noticed that the gas gauge was not giving accurate readings, we had to watch our odometer count to make sure we didn't run out of gas, which is a very scary thought when you have two young children. This happened when we had approximately 80000 miles on the truck and $600 to repair. Shortly after, the transmission was acting up and the heater wasn't working. No why wasn't that working? apparently, Nissan thought it would be a cool trick to have the radiator leak into the transmission.... brilliant business plan they have. Took the truck in and had to pay $5800 to have the transmission, radiator and computer all replaced. This financial hardship was in fact a hardship. One that shouldn't have had to happen had Nissan provided quality parts and provided stellar service. I will sue Nissan for this major safety issue, blog/facebook my little heart away about how insincere of a company Nissan is and never ever-ever-ever give them a positive recommendation.

My Nissan Xterra started making a vibration sound around August of 2011. It sounded like your vehicle was running over a "rumble strip". it was infrequent at first so I ignored it. I did notice some other warning signs of potential trouble (at hindsight). The vehicles heater would never heat the interior of the vehicle at idle, but would do it at speed. Nissan knows the issue is a defect but refuses to take responsibility. Several times while I have been driving the vehicle it would shudder and almost result in a accident. I have only narrowly avoided a collision on 3 separate occasions. Nissan extended the powertrain warranty to 80,000 miles because they know of the issue, but refuse to admit its a defect. Had I been informed about the warranty extension I may have been able to have it services while within the warranty period. My vehicle is currently at 83,000 miles, but within the 96 month portion of the warranty. I'm currently afraid to drive the vehicle on the highway because I'm worried the transmission will fail at high speed and result in a serious accident.

Xterra 6-cyl

  • miles
It has come to my attention during a recent horrific event that my transmission has seized due to a failure of the radiator cracking and mixing coolant into the transmission. I had bought an extended warranty plan through my dealer when I purchased this vehicle in 2009. They had an adjustor from carefree car protection come out to look at the vehicle on Friday November 11, 2011. With that being said; they stated they do not cover the radiator issue; and since it was the faulty radiator that caused the entire transmission to fail and ultimately seized, they will also not cover that or any other of the repairs. Upon a bit of research on my own this is a known failure with this particular year/make/model of Nissan. There are hundreds if not thousands of documented cases of consumers with the very same issue. There has been no recall made on this at all. Yes, Nissan extended the radiator warranty up to 80,000 miles but not the transmission. Guess what; this happened in my vehicle at 89,000, so not only can I not fix the radiator issue but the transmission is also the same. The worst part of all this is; on Wednesday November 9th my four year old daughter and I were almost killed due to this known malfunction. We were traveling on a very busy highway in mid-day traffic when the entire transmission seized in the middle of the highway. I have to say, if it were not for my extensive training in emergency vehicle operations by the state of Massachusetts, I honestly do not believe my daughter or I would be alive today. The vehicle seized right on that stretch of highway and I had to veer into a ditch avoiding other vehicles, trees, guardrails and jersey barriers. I am thankful that we did survive that horrific even. Now I am looking to Nissan to do the right thing and make this right. Updated IVOQ 12/01/11

Xterra 6-cyl

  • 89,000 miles
Recently I experienced a sudden loss of acceleration as I attempted to merge onto a highway. I was also very lucky that I didn't cause a serious accident. The problem was intermittent at first and then increased. Nissan acknowledged a radiator design flaw and extended the basic warranty to lessor of 96 months or 80K miles. I contacted Nissan Consumer Affairs to inform them my Xterra was affected by the same problem. While under 96 mos, my vehicle has 89K miles. I requested an exception which was denied. Nissan's failure to stand behind their products, particularly when the problem represents a serious safety concern and attributable to a design flaw, is inexcusable. Nissan denies any safety concern. This problem (referenced by Nissan in the radiator assembly customer satisfaction program description) pertains to 2005-2010 Xterra, pathfinder and frontier vehicles equipped with auto transmissions. Corrosion within the radiator leads to a crack and contamination of engine coolant with trans fluid, damaging radiator & transmission corrosion develops over time and most vehicle owners will likely exceed the 80K limit before problem presents itself. An internet search revealed 15 dedicated web threads to this problem and they are mostly 2005 vehicles. If Nissan didn"T correct the design flaw before 2010, the # of failures will significantly increase over the coming years as model yr 2005-2010 cars age. How many accidents or fatalities need to occur during this period before Nissan is held accountable for their negligence? the dealer estimate to repair my Xterra is $6,760. This is a significant financial burden and hardship on any vehicle with just over 80,000 miles. How many Nissan owners have to experience financial hardship before Nissan is held accountable?"

  • 89,000 miles
I was driving my 2005 Nissan Xterra at 55 mph on a two lane highway when it began to shake violently as if I had ran over spilled lumber or rumble strips. I braked hard as I thought I had ran over something. I hadn't, so after pulling over and checking for loose tires or driveline I continue on perplexed as to what happened. A few miles later it did it again. Come to find out there is a known defect on 2005 thru 2010 Nissan Xterra's, pathfinders, and frontier's in which the radiators internally leak water into the automatic transmissions and causes the violent shaking at high speeds. Nissan is aware of the issue and has only chosen to extend the warranty on the radiators and not recall the vehicles. In fact the letter sent to the consumers doesn't even reference the transmission (in which it destroys). While my family and I were not hurt, it was a close call and could have easily been worse at the speed I was going and the effect the failure has on the vehicle.

  • 105,000 miles
I was picking up my children from school and my car just stopped driving in the middle of the intersection while I was making a left turn at a stoplight. I brought it to a trans shop and they said I have coolant in my transmission which caused it to fail. Repairs are estimated at $4326 and I am just angry and sick over this situation. Not only was it a scary situation to break down in the middle of the intersection with my kids in the car but I am very disappointed in all the reports I have been reading about in the 2005 Xterra. I can not afford to fix this problem and this is simply not fair that Nissan isn't taking responsibility for their negligence. Please help!!
