Anti-freeze in radiator leaked into trans, flushed it 2x, flushed engine seeing how strawberry milkshake could not be good for engine either. I r&r radiator hoses, thermostat, and belt, went thru many gallons of anti-freeze trying to bleed cooling system. Checked anti-freeze with dye tester, it had co2 from engine in it. BLOWN DAM HEAD GASKET.

NOW I'M LETTING IT GO BACK TO BANK, FOCK. NISSAN DRIVER'S WINDOW FAILED, FRONT WHEEL BEARINGS FAILED, SPEED SENSOR WIRE BROKE NOT ALLOWING 4WD LAST WINTER...I'M LETTING IT GO BACK TO THE BANK. NISSAN'S ARE A POS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The repair shop is telling me that it will cost approximately $5,500 to replace the transmission w/radiator using re-certified parts, and that's after a 10% discount on labor that's normally $110/hour. I didn't know about this issue when I bought the car used with 90K miles on it. Guess I should have checked first.

Question - is the dealership responsible for checking for these types of issues? (yeah, I'm sure I know the answer to that one).

This vehicle also has an airbag recall on it. They informed me there was a recall but said it wasn't anything to worry about. I thought it was a wheel bearing issue, they didn't tell me it was an airbag issue.

Update from Apr 25, 2015: Had I known this was a possible issue I would have known what to look for when I was told the radiator had to be flushed - prior to the car turning 100K miles. I spoke with NISSAN and they told me that since the problem was diagnosed after the car reached 100K miles, they were "under no obligation to provide assistance". It didn't matter to them that the issue occurred prior to 100K miles and that the mileage at diagnosis was only 100,425.

My car started stalling at around 98,000. I took it to a mechanic who confirmed this car was having problems associated with a recall. He seemed to know exactly what I've been reading here.. that the coolant leaks into the transmission and then transmission fluid back to the radiator and eventually the motor.

He quoted me an approximate $3,800 to rebuild the transmission and replace the radiator. And that "might" just do it. After that, I kept using the car "as is" to work and back because I HAVE to get to work & I am still making payments on this piece of sh*t car. After about a month after the stalling began I parked my car when I got home and it never turned back on again. I cannot afford to pay 4 grand to get this fixed. Am I seriously going to just have this car repo-ed? I need to get a car to get to work, therefore I will no longer pay for this one and my credit will be ruined.. Thanks NISSAN for not backing up your product... you know who really backs up their cars? Toyota... Should've stayed with Toyota!!!

My car began shuttering bad enough that I was afraid that it was going to stall or that I would get into an accident. Thankfully, I didn't. I found out that a faulty radiator had leaked into the transmission. Apparently, this is a well known problem. I am being told by Nissan that it will cost $7,000 to repair/replace the radiator, hoses, transmission etc. My mileage is just over 106,000 miles so, like everyone else, I will get no help from Nissan in making these repairs. I can't afford to fix it at this time so it will have to sit and wait while I will pray that there is a recall soon.

My car stalled on the highway and almost caused me to get rear-ended. I was shocked to find out that this is a known defect and known safety issue! My Xterra is in mint condition with the huge exception of this radiator defect which has now caused the need for replacing the radiator and the transmission (to the tune of at least $6000)! Had Nissan replaced defective radiators when the problem became known it would have saved the owners of their product potential accidents, not to mention thousands of dollars. There are companies today who take responsibility for their product defects, but it seems, sadly, that Nissan is not one of them. I'm thankful I didn't get rear-ended when my car stalled. I am frustrated that Nissan has not yet taken responsibility for the proven defect in their product & they, as of now, are telling me the responsibility for over $6000 in repairs, for their known defect, is mine!

Started having transmission and cooling problems at about 98,0000 miles on my 2007 Xterra. Took to mechanic and they couldn't find much wrong until recently. We just discovered the vehicle is one of the MANY Nissans to have the radiator crack and leak coolant into the transmission and transmission fluid into the cooling system. Now of course vehicle has 106K miles and Nissan won't help us! There was a class action lawsuit against Nissan and as part of that they agreed to offer incentives, albeit skimpy ones, for any vehicles under 100K miles.

Ridiculous! This is a known defect effecting thousands of vehicles and Nissan has done nothing and now we are looking at a $4K-$5K repair bill. This is criminal and as an owner of multiple Nissan vehicles makes me feel like Nissan could care less about its customers, especially loyal ones!

Update from Apr 28, 2015: Despite numerous complaints to all regulatory agencies and direct conversations with Fred Diaz's office (VP Us Sales and Marketing), Nissan has done nothing to even help with this issue. The dealer quoted me 7500.00 for a replacement so having it done by a private mechanic and will still cost me almost 5000.00! Unbelievable arrogance from Nissan and since this complaint was filed there have been numerous stories, including one on the Today show, about Nissan's refusal to assist customers or even recognize their problems. Unreal and this should be criminal. Here is the corporate contact information for Nissan and I was dealing with a woman named Elizabeth in their corporate offices in Tennessee. The refused to even acknowledge the existence of the THOUSANDS of cases just like mine.

Bought this vehicle in fall of 2012 and was never contacted in regards to a class action suit ....my vehicle has now

Had the same transmission failure as all the others and I was basically left out to dry and find a solution for my

Vehicles failure. It is unfair to have these vehicles not covered !! This is Nissans costly mistake and it's very sad the customers are stuck with the repairs!! They should have recalled these vehicles or taken them off the market because they all eventually have failed transmissions due to the radiator fluid flowing into the transmission!!!

I believe they made these vehicles knowing they would fail at 100,000 miles and shaft customers like me!!

My 2007 Nissan Xterra is at the Nissan car dealership with work order of a new transmission and radiator due to the manufacturing defect of the radiator assembly. I have spoken with Nissan's customer relations and they will not stand behind their product and help with the expense of these major repairs, even though they know this is a major design and safety defect.

I did receive a Warranty Notification that down played the severity of this design defect stating "the majority of vehicles will not experience this issue". I have found this statement not to be true. Most (if not all) will experience this malfunction. In addition, their notification only covers up to 10 yrs/100,000 miles, whichever comes first. They are well aware that these repairs will be needed at higher mileage. My vehicle is only a 2007 and if Nissan was building a quality product it should not be in need of a new radiator and transmission. Since their cap is the 10yr/100.000 mile and my Xterra has 134,000 miles, they just apologized for my inconvenience and let me know they will not be assisting with any repairs.

My question is do I have any recourse? How do I get another lawsuit to extend the mileage to cover a higher mileage? I know Nissan is a big corporation so they have tried to appease their customers with a warranty, that to me, is insufficient and irresponsible. They know about the defect and they also know it occurs at higher mileage so that is why they put the cap at a lower mileage so they can't be held responsible.

I park the car and when I came back couldn't start. Thought it was a battery problem. Tried jump start with my other car, no luck. left in the parking lot for a few days. Came back and hook my code reader and it shows U1000. U1000 is ground harness problem. I tried to clean the battery terminals both sides but no luck.

So towed the car to DARCARS Nissan and they told me need to replace radiator and transmission. They said will cost $4700…So I started researching and found out that NISSAN Xterra 2005-2007 and even new models had radiation fluid leak into transmission. So how am I supposed to know if I have harness grounding problems or “radiation fluid leak into transmission” dang. DARCARS Nissan Service Center never mentioned anything about code U1000 when we took the car. So now, what the hell am I supposed to do?

This is round 2 for me. 2007 Nissan Xterra. Last March it started with the thermostat going out. Found out about the intermix problem in May and had the radiator replaced to the tune of about $600. That lasted for 9 months until the valve body/transmission module just failed ~~ new transmission required for almost $5000.

Nissan dealership says basically too bad, they settled.

HOWEVER!!! there is good news! I spoke with the attorneys that handled the 1st class action lawsuit. The one that bumped the warranty to 90 or 100K miles. He said that since my vehicle was over the 100,000 mile mark before the problems manifested themselves, that I was EXEMPT from the first lawsuit and eligible to file a separate class action law suit.

SO, here's the question...

HOW MANY OF YOU HAVE BEEN IN THIS SITUATION? YOUR VEHICLE WAS OVER 100,000 MILES BEFORE IT EVER SHOWED ANY PROBLEMS?

WILL YOU JOIN ME IN FILING ANOTHER CLASS ACTION LAW SUIT AGAINST NISSAN? SHALL WE AT LEAST TRY?

I noticed a vibration, like you were driving on the rumble strip on the side of the road between 40 and 50 mph, at around 2000 rpm. I took it into the dealership and the service tech diagnosed the problem, cooler system failure, in about 5 minutes after taking one look at the transmission fluid and coolant it's such a common problem. They replaced the transmission and cooler assembly. I had just under 97,000 miles on the vehicle and had to pay $3300 for the repairs.

This is my third Nissan and if anyone had asked me before what my next vehicle was going to be I would have said, another Xterra. However, I am very disappointed in Nissan and how they have handled what is clearly a prevalent and known issue with cooler failures in certain models. A $3000 deductible (plus tax) that expires at 100,000 miles for an issue that's known to occur at close to 100,000 miles is not much of a consolation. A quick Google search of "2007 Xterra transmission" brought to light how common this failure is.

Purchased 2007 Nissan Xterra with 15,000 miles on it. Took really good care of it and had no issues until recently the truck started to Shutter on acceleration. Put brand new high end tires on, alignment, tires balanced. Tire shop said they saw nothing wrong underneath. Took it into local shop and they told me my transfer case was bad. Had transfer case replaced, still shuttering, even more now. Looked online and read tons of other complaints and youtube videos describing the exact same symptoms and the radiator issue. Went into my garage, checked the coolant and sure enough it's got ATF in there. Drained my transmission to find a nasty milky sludge. Truck has 90,581 miles on it and looking at paying the dealership the $3,000 they want with their extended warranty on this known issue. WTF? Wish I knew about this issue sooner so I could of done something earlier. I actually bought this truck with Nissan Reliability in mind. Feel sorry for all the people who don't have the money to fix this nightmare of a problem. Thanks Nissan.

My vehicle failed the other day and I had it towed to the Nissan dealer and they told me it was the transmission because the coolant leaked into it. I was told by the dealer it would cost me $6200 to fix it. I am looking at another option for repairs as that seems really excessive. My local mechanic is pricing it up for me, it won't be cheap, but it may be more like $3500

My Xterra is not new (2007) and has a lot of miles on it (165,000), but this vehicle failed because of the manufacturer's defect. Looking at the number of complaints and people who had this issue, Nissan should be stepping up and doing the right thing, but they won't. The dealers are raking in the bucks on the repairs. The only people screwed here are the car owners.

It's a real shame, because I loved the vehicle.

Update from Apr 28, 2015: Had this fixed at my local repair shop for $3500. I wish I had known about the issue prior so I could have switched out the radiator before it leaked. Not happy about having to spend that kind of cash on something that could have been prevented.

Update from May 19, 2016: I had the vehicle fixed at a cost of about $4000, including a new radiator.

I just bought my Xterra in the beginning of July after getting a $10,000 loan to pay for it. The dealership (Transitowne Amherst) told me all it needed was brakes and tires that they will replace before I take possession of the vehicle and that nothing else was wrong with the vehicle. September comes around and I needed both brakes and tires so I replaced them. Then the Saturday before Thanksgiving I go to leave my fire hall from a call and it wont start. I had it brought to Mike Barney Nissan and they call me to tell me it's going to cost me almost $7,000 to fix because the radiator, and transmission are both shot and that the rear leaf springs are both cracked. NEVER BUY FROM ANY TRANSITOWNE!

In 2012 I bought a newer, but used, 2007 Xterra from a Nissan dealer in Canada (the car was from US but had been registered in Canada). The vehicle had 60 000 miles on it. At 102 000 miles I took it in because of a small problem I had noticed with the transmission that started to get worse. I was told at Nissan that this was a common problem and it is going to cost 8500.00 dollars to fix. Had I brought the vehicle in 4 weeks ago when it was less than 100 000 miles it would only cost 2500 dollars.

When I talked to a Nissan warranty adviser she said tuff luck. When I explained why I was upset and asked her if she felt that Nissan was handling this problem fairly, she told me that I shouldn't have bought a vehicle that wasn't meant for the country and environment that I live in.

Thanks for that Nissan--This is probably the rudest person I have ever dealt with when dealing with an issue this large and expensive. When I asked her why Nissan never let me know of these potential issue she replies that US and Canadian Xterras are very different and made in completely different places-- While this may be true, I am not sure it is still well known that both US and Canadian Xterras are plagued with the same issue.
