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!!!

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.

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?

Driving my 2005 Nissan Xterra I purchased 8 months ago in January 2013, my air conditioner worked intermittently. Eventually in July of 2013, my car was not drive able. Had it towed to dealership I purchased it at, and they verified that my radiator was leaking coolant, which mixed with my transmission fluid. The resulted in the need to repair the radiator and transmission.

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.

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.

I have had my Xterra for 7 months when one day I was approaching a very busy and long intersection when my Xterra went into a safe mode and lost most power which had me hoping on coming traffic would not tbone me as I could not accelerate through. The local dealer told me that this was all electrical and I would need two wire harnesses and a ECM. This cost 3,800 dllrs. After replacing those parts they told me I needed more work due to my radiator and transmission having cross contamination due to a defect, bad weld on the radiator from the factory, but yet im still responsible. My new total bill is roughly 9,000 dlrs which is more then the vehicle is worth. They have mis diagnosed this from the get go and will not take any responsibilty or ownership. Nissan has been the worst to work with. They have had my vehicle for over a month and I have been told it was first my ECM computer then a fuel injector, ignition coil, then wire harnesses and now a new transmission and radiator. Basically if you go to a dealer and the tech has no idea what hes doing they will call a support line and make you pay for the parts until they can narrow down the problem. Now they are linking everything together with some bogus theory and im financialy responsible. Why is it up to me and my wallet to pay for parts when it should be on them to properly diagnose the issue for the get go. They told me ignition coil and injector were the problem. I have not since heard about those parts only because they didnt replace them in his blind search to pinpoint the real problem. I could have been seriousaly injured if other drivers were not paying attention. Im thankful that was not the outcome or Nissan would have been paying me a large sum all due to they will not recall this 600 fix. Its bound to injure or kill someon in the future. I will never buy another nnissan again. Horrible service and product.

I have about 113,226 miles on my 2005 Xterra. The other day I had driven my car to work with no issue and left for lunch again with no issues. However, when I got in my car to return to work from lunch, I had started the car with no issues, put in drive and when I pressed on the gas it felt as if though my car was stuck in neutral. I even checked to make sure it was not. I released the gas and pressed on it again and the went however every time I had to stop and go again I had to floor the gas in order to get it going. Once it got over 25mph it seemed to kick back into gear. I took my car to the Nissan dealership right away to find out what was wrong with my car, since it had been working fine up until lunch. Today I got a call from Nissan telling me it was an issue with a radiator fluid leak into my transmission and that the fluids had mixed and that I would now need to replace the transmission and radiator. The thing that gets me in that my car has been to Nissan twice in the last year for issues with my transmission, and with the first time it was in for repairs they told me there was a small leak with the coolant and yet said nothing to me about this issue nor about the extend warranty (10 years/100,000 miles) which if I had know about I would have had them check at that time to make sure the leak was not related, and if it was would have had them fix it. But instead they let me take my car and now I am faced with a estimated $6K repair job.

Fortunately I was simply attempting to back out of my driveway when the vehicle would not move. I read numerous horror stories of others who had this issue in the middle of the highway so I am very thankful that this did pose any further risk of injury especially since I am 9 months pregnant and was on my way to an ultrasound. After taking my SUV in, we learned that anti-freeze was leaking into the transmission causing complete transmission failure and ultimately requiring a full transmission replacement. The cost is closing in on $4,000. Never did I receive any notification from Nissan that this was possible and my Xterra did not show any signs of concern. I started researching this problem online only to learn that I am one of many who have experienced this issue and at a hefty price with no help from Nissan. I read online that Nissan's answer to the problem was to extend the warranty to 80,000 miles but I have just recently passed that threshold. Furthermore, I have learned that this problem more often begins to present itself after 80,000 miles. I am appalled that this issue has not been investigated and more importantly been recalled since it could cause serious injury if not death. One thing is for sure, my husband and I will never purchase another Nissan vehicle. I strongly feel that the NHTSA should analyze the way Nissan is doing their business not to mention find a way to compensate every single customer who has suffered from this problem. Nissan should be ashamed of themselves and hopeful that no one gets seriously hurt should it occur in the wrong circumstances.
