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.

Xterra 6-cyl

  • 106,000 miles


The car began to vibrate at 40 mph. I took it to two mechanics who could not figure out the problem. I tried regular maintenance and tire rotation and balance but the vibration continued. Finally, while I was out of town, a mechanic dropped the transmission pan and discovered the engine coolant had entered the transmission system. He discovered that this is a problem with the Nissan Xterra 2005 - 2010. Nissan even has a bypass part to be installed. This piece was installed and the transmission flushed and new transmission fluid put in. The radiator appears to be fine, no cracks as often reported with this problem. Now, three months later, I have serious transmission problems. The car jerks violently at 40mph on acceleration and deceleration. The mixing of engine coolant with the transmission has obviously caused serious damage to my transmission. I am devastated. I love this car but have no financial means to fix this problem.

Was driving while my transmission went out. Dealer said the transmission and radiator fluid were mixed. My vehicle had 99,000 on it. Had it fixed then at 140,000 it happened again. Nissan wants me to pay $5500 but I refuse. This vehicle needs to be recalled.

My transmission just stuttered and stopped working while in traffic.turns out the radiator leaked coolant into the transmission causing it to fail. This is a known issue from Nissan, however the cost of the repair fell to me. Luckily, I did not incur any injury when the vehicle just stopped working during 5pm rush hour on a Friday.

Xterra 6-cyl

  • 124,356 miles


While turning back into traffic my 2005 Nissan Xterra jerked as I began to accelerate over 20 mph. Once I got the vehicle to the speed of traffic it began to have troubles shifting gears and accelerating. While the vehicle was at a steady speed I didn't notice any other issues. As I slowed to an exit the vehicle started to jerk and not shift properly. It also had trouble accelerating. After having these issues I checked my fluids and found a milky like substance was in my transmission and my coolant. I researched the problems I was having with my Xterra and found that it was very common and realized that their is a crack in my radiator which is causing the contamination of my transmission and coolant. I have had this vehicle for just about two months and it is very upsetting to know that I may have to pay for a new transmission and radiator which is more then what I paid for the vehicle.

Xterra 6-cyl

  • 117,000 miles
Car was not running as it should. We thought it was tires and had the tires looked at. Then the service engine soon light came on but then went off. Cruise control stopped working. Then service engine soon light came back. Monday made appt for Nissan dealer (scheduled for Wednesday). By Tuesday morning, could only use 3rd gear so dropped off to dealer on that Tuesday. Nissan diagnosed: Radiator and transmission mixed and contaminated which damaged the tmc. Recommendation: Replacing transmission and radiator assembly (est $6600). We took to a transmission place who was well aware of the defect of this model and indicated that Nissan would be fixing the problem but they are just repeating the issue and the problem could occur again. A flaw in Nissan's design is what we have heard and read about. We didn't want to risk it with Nissan so we had repaired elsewhere. We only had 117,000 miles.

Xterra 6-cyl

  • 158,000 miles
Suddenly the car (automatic) was revving high and not shifting into next gear and starting making ahigher pitched noise and the service engine light then came on. I drove to a gas station and before fully pulling in, my car would not go into drive, revved high and started smoking. I had to get towed and my car is now going to need a complete transmission and radiator. Nissan is saying since I am passed the extended 10 year warranty or 100,000 miles, there is nothing more they will do about it. Currently am being transferred to see if someone else cares enough about Nissan image as well as their drivers to do something about this. I have been quoted it will cost $5100 to repair this Nissan known issue.

Xterra 6-cyl

  • 118,830 miles


I was informed by the dealership service department that radiator fluid had contaminated transmission fluid in my 2005 Nissan Xterra. This defect in the radiator was known to occur in high mileage vehicles such as mine and was known to Nissan as they extended a service warranty to 100,000 miles. Unfortunately, my vehicle's mileage is over the extended warranty and I am now responsible for the cost of the repairs. This is a huge safety issue as the transmission plays a vital role in the ability for the vehicle to accelerate into and across traffic on busy highways and roads. The inability to do so properly with a defective transmission may lead to accidents. Not to mention that the contaminated radiator coolant may not accomplish the intended goal of cooling engine components leading to over heating and engine dysfunction. I feel strongly that Nissan new about the defect and did not take appropriate action to notify consumers to have the radiators replaced prior to having complications from the defective parts.

Xterra 6-cyl

  • 105,689 miles
Driving Xterra on highway when SUV started to hesitate when moving forward in traffic....SUV would hesitate, rev...and not shift out of gear easily upon acceleration. Took SUV to mechanic and found out the radiators engine coolant was leaking into the transmission fluid causing the problem. I lucked out and did not damage the transmission, however; I am having to replace the radiator due to the Nissan known defect. I was never given any letters or notified about this mechanical problem and now will be paying under a $900 for fluid flush, new radiator and new fluids. This is not ok for Nissan to not notify the vehicle owners!!!! I expect repayment from Nissan on their faulty mechanical equipment.

When I drove it to work, there were a few delays while shifting gears. After half hour driving it, I heard water splashing sounds. I turned off the radio and I heard the splashing sounds even more clear. In the same time, I smelled electronic burnt like smells. Since I was on the express way, I couldn't stop right away. Then, 15 minutes later or a total of 45 minutes driving it, there were smokes from the front. I was so shock and worry if the car was going to blow up. I felt panic because I couldn't just stop in the middle of the driving lanes. Thankfully, other cars slowed down for me and let me passed. I pulled up in the nearby dairy depot's parking lot, but I was 20 minutes away from my workplace's city. It was so cold and windy, but since I was worry if the car would blow up, I got out and stood in the cold. Also, the tow truck was delayed for 2 hours and I had to missed work. The car shop told me that the radiator causes the transmission issues and all fluids are mixed together. When I researched this issue, I came across many others who had the same issue. I am shocked that it's very common. I feel so discourage to ever trust Nissan again. This car was my investment as I have $7000 loan remaining on it and I just fixed all four shafts for $1000. I have always done comprehensive maintenance to it. So, where did I go wrong" how can Nissan does this? why there was no recall that would have regained customers' trust that it is safe to drive Nissan??? why Nissan has to wait for a mountain of complaints before agreed to extend the warranty and even that was only for those under 100K mileage? does it mean that Nissan can't make a car that last more than 100K??" not only Nissan jeopardizes my safety and others, now my investment in Nissan has turned into a chunk of debt for me. This is so wrong!!!

Xterra 6-cyl

  • 146,000 miles
Due to a faulty design by the manufacturer, transmission fluid leaked into the radiator and caused complete failure of the radiator and transmission. Because my vehicle had over 100,000 miles it is not covered in any way by warranty and there was no recall issued. I am now facing a car that is worth $7000 or so and needs more than that in repairs. My vehicle is totaled thanks to a faulty design that has been well documented by the manufacturer, but they will do absolutely nothing to help. If they had simply issued a recall on the radiator when the problem first became known, this would have been and easy $500 fix, instead I am left with a worthless vehicle and insufficient funds to repair it or get a new one. I could not be more angry and disappointed with Nissan and their handling of this situation. Needless to say I will never be buying from them again and I will suggest the same to anyone who will listen.

Our radiator and transmission broke, causing our car to stall, on vacation, in the middle of Utah. Apparently Nissan is aware of this problem but the warranty is too limited to cover Nissan Xterras suffering from the exact same problem! it's not just us!!! we use our Xterra for off roading (as its intended for!) and a busted transmission put all of us at risk! we did not do anything crazy but you need a safe transmission on hills. After over $1000 in towing expenses we got to a Nissan dealership where we were informed that there is nothing we could have done to prevent this. Later we researched and found out it is a common defect in cars like ours.

Xterra 6-cyl

  • 94,000 miles
I took my 2005 Nissan Xterra to dealer to get serviced. The service department person told me my transmission fluid was leaking into radiator. They told me do to my miles on car at that time I had 94000 miles it would be a 3000 dollars co pay due to the extended warranty Nissan had authorized. I ask why wasn't I told when Nissan was aware of problem to do prevented maintenance. The service rep. Said since it was no recall he was not obligated to tell me. I don't know about most people but I don't have 3000 dollars laying around to use I live paycheck to paycheck. I take my car to dealer only for service thinking its getting the right service but I found out I was wrong. If I was advised early I may of found this problem earlier and got it replace free. Now what do I do?

Xterra 6-cyl

  • 85,255 miles
Check engine light came up in my 2005 Nissan Xterra at 85,000 miles. Took it to the repair shop where I make oil changes, I was told transmission broke and radiator fluid contamination. Took it to the dealer, they confirm that the transmission failure, but they flat out refused the contamination, instead offer to replace both transmission and radiator for $5,500 to avoid future problems. I was not convinced. Immediately, another guy in the dealership offers to trade in for a new car. I took the car out and went to another transmission shop. Sure enough, they noticed radiation fluid contaminating the transmission fluid. Cost was around $3,750. Because, the deadline was early June'2013 and now is early July, they are telling me I cannot submit the claim. I hope the court does not approve the final settlement. Nissan should recall and pay for the repairs of defective transmission/ radiator.

While driving my 2005 Xterra SE noticed loud noise coming from front end - found out transmission fluid had become mixed with coolant from radiator. (I have a sample of the cloudy looking fluid). The problem rendered the SUV undrivable so was towed to dealer where spent $5,400 to have both transmission and radiator replaced, but do not know for sure if this a permanent fix or not.

Xterra 6-cyl

  • 133,242 miles
The vehicle was being driven, as normally, to work on the highway. The engine started to accelerate but the vehicle kept slowing down. There was very little power. The vehicle was brought to a Nissan dealer. The mechanic at the shop told me the transmission had been damaged due to a failure of the radiator. The radiator, transmission and trans computer would have to be replaced at a cost of $4500. He also mentioned that this is a problem Nissan knows about but will not cover the repair under a recall or warranty. I took the SUV for a second opinion to a reputable repair shop. He confirmed the findings of the Nissan mechanic and offered to repair the vehicle for $4,140.47. I agreed to have the vehicle repaired. The mechanic said I should look up a class action suit that has been generated. That is why I am posting this incident.
