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?

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.

A radiator failure caused the cooling system fluid to mix with transmission fluid causing transmission failure.

- Colchester, VT, USA

I have experience what many other owners of a Nissan Xterra have experienced with a defective radiator. A leak in the radiator has allowed coolant to mix with and contaminate the automatic transmission fluid, resulting in damaged internal transmission components and a damaged internal transmission computer. In less than a week since noticing loss of power in my vehicle it became inoperable. Due to the high number of these incidents involving the Nissan Xterra transmission parts have become impossible to find to rebuild the transmission. As a result they only recourse to resolve this problem is a costly $6000 replacement of the transmission.

Radiator leaked onto transmission. Learned about their faulty radiators just today. Now I'm in a $6200 bind to get a new radiator and transmission. I take good care of my Xterra and I am so appalled with Nissan I don't know what to do with myself. A $600 fix turned into a $6200 fix.

The radiator has leaked many times which has caused the transmission to go out.

I was driving on the highway around 70 mph. Experienced a loss of power followed by my car running hot. I pulled over and had the vehicle towed to my repair shop. Diagnosis was the radiator was leaking coolant into the transmission. The radiator was replaced and the transmission was flushed. Total costs $900. Possible damage to the transmission unknown at the time. The car is now back in the shop with the same issues slipping/grinding at highway speeds. Looking online it seems that a number of people have the same problems with a leaky radiator hose. I spoke with a Nissan dealership and Consumer Affairs and they said that nothing can be done.

On September 8th, 2012, I got back from a 20 minute trip and was pulling into my driveway when my Xterra would not move. Transmission fluid was leaking all over my driveway. I had it towed to a service center where they estimated the cost to be between $2,500 and $2,800. When they realized the transmission and radiator had to be replaced the repair bill would have been much higher but they kept their promise and the final bill was $2,856. I am thankful that this did not occur on the highway. I should not have to pay for a defect that is not my fault and that is a possible safety hazard.

Just started moving after stopping at a light, and the engine stalled. Would not restart immediately, but when it finally restarted it was missing. Every time I have driven this car since then it has stalled, usually but not always after I have stopped or slowed to make a turn. I took it to the dealer this week (1/5/2013) and was told the problem is the transmission and radiator. The transmission is leaking fluid into the radiator and they both need to be replaced. I was told about the extended warranty and the $3000 co-pay. I have to fix the car but I don't know where I'm going to get $3000. I don't understand why Nissan didn't recall the part that fails which allows the fluid to leak into the radiator. That would have saved hundreds of people and Nissan a lot of trouble and expense. There shouldn't be any co-pay since Nissan could have prevented this.
