Problems with 2007 Nissan Xterra POWER TRAIN

Transmission over heats due to radiator hose corrosion.

2007 nissan xterra. consumer was told to pay a $2500 copay because his vehicle was over 80,000 miles. consumer doesn't comply because he inquired about vehicle problems before the 80,000 mile mark. *ta the consumer stated while his was driving, she noticed the vehicle began smoking and the check engine light illuminated. the vehicle was taken to the dealer, where a diagnostic test revealer the radiator and transmission needed to be replaced due to coolant and oil mixing. *jp

It has same problems as all the 02-08 xterras but you wont issue recalls on fuel sensor, radiator leaking into tranny, air bag sensors, control arm. thanks for letting loyal nissan owners down!!!! *tr

Tl* the contact owns a 2007 nissan xterra. the contact stated that while driving at 45 mph, the vehicle experienced transmission failure. the vehicle was taken to a dealer. the technician diagnosed that the transmission and the radiator needed to be repaired. the vehicle was not repaired. the manufacturer was made aware of the failure. the approximate failure mileage was 126,000. updated 7/14/15*cn

My xterra would not accelerate from stop to start, then one late evening it would not start at all. i had it towed to my mechanic who said it was the transmission that needed to be replaced and the transmission was shorting out the fuse to start the car. i took it to another mechanic for a second opinion, he stated the same and this was a known defect in xterra, he also said that it will cost thousand of dollars to fix and even with a new transmission it will likely happen again because the electricity will burn out because of the defect. i called nissan dealership, who stated that they knew about the problem, but was going to help fix it or reimburse me anything. i was stranded with a small toddler at 10pm in the rain and no means of getting home thanks to nissan's known defect. *tr

I bought my 07 xterra 6 months ago from transitowne amherst and the dealership told me nothing was wrong with the vehicle. now 6 months down the road the transmission has gone terminal due to the known problem where coolant leaks into the transmission and causes it to fail. i believe any dealership should have checked to make sure that a vehicle they were selling would not have this issue before they sell it. *tr

Was told by dealer that a known problem with radiator caused radiator fluid to seep into transmission causing transmission to fail. neither dealer nor nissan would accept responsibility for this known defect. *tr

Sitting at light in the left lane, waiting for it to turn green and all of a sudden the car started making a loud racing sound. not sure if it was transmission or engine making the noise. i looked at my gauges and saw the temperature gauge was on h. i had to wait for the light to turn green, because i was at an intersection, in the left lane, to get on the highway and there were cars on my right and cars going in the other direction. as soon as i could move, i pulled over to a safe spot, but before i could, the car started overheating and smoke started coming out of the hood. it was towed to my garage and after my mechanic looked at it, he said this is a known issue for nissan xterras 2007, because the radiator is defective. the coolant mixes with the transmission and the car stops running! apparently, nissan knows that the part is defective so they extended warranty to 80,000 mile and anything past that i have to pay. well, i have 90,400 miles and can't believe that nissan can get away with knowing a part is defective and not recalling all trucks affected. they certainly changed the radiator design for the newer vehicles, admitting that it is a problem. they should recall the cars and replace the defective part. it is all over the internet, because the problem is so widespread and nissan will not take ownership of it!!!!!!. please look into this and look on the internet to see how common this issue is for xterras and all the people that got screwed by nissan. thank you. *tr

While driving at a highway speed of 70 mph in the left lane of an interstate, the transmission completely failed. there was traffic in the right lane. i was unable to move to the outside shoulder until i was traveling at 30 mph. this was very dangerous, especially due to trying to merge between semis that were in the right lane. after towing the vehicle 75 miles to get close to home and at a trusted repair shop, i was told that the coolant leaked into the transmission system (like so many others). this caused the complete failure of the transmission and contamination of all of the lines and gaskets. the vehicle would not travel forward or backward. this appears to be a known issue, based on the large number of complaints on the web and the class action lawsuit. the repairs are estimated at 5,000 to 5,500 dollars, plus the towing. most of the problems, including mine, occur after the extended period. due to the rapid failure, this is an extremely unsafe condition. *tr

The radiator fluid leaked into the transmission and ruined the transmission and valve body assembly. the car will not run and stalled out in an intersection. *tr

This is one of the many transmission issues with 2007 xterras where the coolant leaks into the transmission and destroys it. the repair cost is 8500 dollars if the 100000 mile extended warranty has been passed. i contacted nissan and they told me that this is my responsibility despite the hundred of complaints regarding the exact same issue. when driving at any speed, when the xterra changes gears there is a rough vibration that keeps getting worse the longer it goes for. had i not learned about this on my own accord this could have resulted in a very bad accident. *tr

Car will not upshift sometimes seems electrical. *tr

My 2007 nissan xterra came on with a check engine light and over drive indicator light stayed on. obdii code for check engine light was p0700 transmission control system tcs malfunction. the transmission would no longer use 1st, 2nd, or 3rd gear. reverse, neutral, and drive could still be selected but when in drive it was in 4th gear only. took it to the nissan dealership and they told me that coolant from the radiator was leaking into the transmission and this was a common issue that the service department had seen before many times now. they informed me that i was 1500 miles over warranty and that i would have to contact nissan customer care. that is when i discovered that there was a class action lawsuit for this problem against nissan because this was a known defect for 2005-2010 xterras and they wouldn't do a recall. now nissan is telling me there is nothing they can do for me and they will charge me $7500 for parts and labor to replace the transmission, radiator, lines and fluid. that is outrageous as my 2007 xterra only values at $8000. i was never notified when i bought this suv in august of 2012 that it was part of a class action lawsuit and in the 2 years i have owned i have never been notified by nissan of a settlement that could have alerted me to have this checked sooner before transmission failure happened. i also wouldn't have bought the car if i had known there was a known issue with the radiator leaking into the transmission that nissan is not willing to recall for. now i am trapped with a loan on a lemon i cant drive and cant afford to fix. *tr

Engine coolant and transmission fluid mixing causing overheating and transmission failures. *tr

The radiator used in my 2007 nissan xterra is a faulty product which caused a leak of the radiator fluid into the transmission fluid system. when the transmission heats up during longer periods of driving, the radiator fluid also heats up and effectively ruins the internal transmission parts. this has caused several issues in the shifting of the vehicle, and often times in very dangerous situations where acceleration is key to avoiding accidents. *tr

I have an automatic and noticed that my 07 nissan xterra was struggling to change gears. when it did not go away after several months, i took it into local repair shop. they found that the radiator was full of a brown milk shake substance. they determined that transmission fluid had leaked in the radiator and mixed with the antifreeze. the shop replaced the radiator. flushed the antifreeze system and the transmission fluid. 6 months later, the transmission started stuttering when it was changing gears at 45 - 50 and 65-70. i took the car into a local aamco. once i advised the service rep what type of car i had, he laughed and said they that had already rebuilt over 30 xterra transmission. they checked the transmission and advised that it needed to be rebuilt and provided me with an repair estimate of $ 4200. they advised to call nissan consumer affairs to see what they would offer to do. they also advised of a class action lawsuit against nissan for this known defect. i have been unable to find any information on this lawsuit. *tr

A defect caused a crack in the transmission radiator which leaked fluid into the transmission causing unexpected catastrophic transmission failure. *tr

My transmission is ruined because both the radiator antifreeze and the transmission fluid have mixed. my wife could have had a serious accident. *tr

Radiator leaked into the transmission. *tr

I purchased a 2007 nissan xterra 200 miles away from my home and while driving it home the vehicle transmission stopped working properly. the vehicle drove ok at highway speeds but once i slowed, to in town speeds, the vehicle lost the gears ability to drive the vehicle. if this occurred to me while on the highway i could have been in a much greater danger. this more than likely has occurred to others that own these types of vehicles, putting them in a very unsafe environment. if there was fluid loss or overheating it could lead to a vehicle fire as well. i would like a recall to occur for the transmission/radiator crossover to the 2005-2010 nissans - xterra, pathfinder, and frontier. *js

Transmission failure while merging in rush hour traffic. vehicle suddenly dropped out of gear, then stuck in low gear without warning. vehicle had to be pulled off the freeway immediately to avoid causing accident. *js

I pulled on to the interstate on which the speed limit was 65 mph, and my xterra would not shift past second gear or go above 35 mph. cars were flying by me and those entering interstate behind me were unable to get around me due to the high volume of vehicles on the interstate passing us. i turned on my flashers and limped it to the next exit to get off the interstate. the transmission failed due to coolant being leaked into it. this issue has been investigated and a class action lawsuit settled. however, it was only up to $100,000 miles and i can no longer be part of that lawsuit. i never received notification of an issue with my make and model vehicle. this issue is continuing to happen to other xterra owners and putting others at risk. nissan knows about the problem but refuses to take any action to correct it. in fact, according to my mechanic, the valve needed to correct the problem is on back order with nissan due to the high volume needed for repairs. apparently, they cannot keep up with production of them. *tr

This week my sons 2007 nissan xterra would not start and we had it towed to a nissan dealership near his college in scranton pa. yesterday we were informed that the transmission and radiator need to be replaced, at a cost of around $5000! this is shocking because my son insists that he noticed nothing amiss with the operation of his truck until it he was unable to start it. after spending 10 minutes on the internet, i learned about the nissan transmission class action lawsuit. we have been religious in terms of scheduled maintenance, and overall care of the vehicle. we were not aware of the cooling/transmissions problems plaguing nissan trucks. in addition, i have had the vehicle serviced at two separate nissan dealerships, one in new york and another now in pa. it is disgraceful that neither nissan dealership mentioned anything! this morning i contacted nissan corporate and was told that since the vehicle is over 100,000, there is nothing they can do for us. i do not have $5000 and do not know what to do with my sons nissan. as others have mentioned in postings, there likely many others with vehicles over the 100,000 marker, now just experiencing the negative effects of the defective manufacturing by nissan. there should be a second class action suit filed against nissan!!! *tr

There is a known service problem and bulletin on defective timing chain guides that cause a chain to skip, break lose , or break causing the vehicle to go into a high speed stall. my is just grinding, will repair, but nissan is well aware of this problem and won't participate in a solution. *js

Radiator and transmission failed while driving on highway, part was settled in class action suite and owner was never made aware of defect and or how it can be fixed until failure on highway with family of four in it on 3/28/2014, the owner is the sole owner of vehicle since 2007, owner never received any information at all from nissan regarding this manufacturer issue until service department at nissan informed owner of issue and also informed owner of $3,000.00 repair charge for the faulty parts. *tr

I was driving on the highway in my 2007 nissan xterra with my family (myself, my wife, and 2 children). we experienced a complete breakdown while traveling 60 miles per hour. the truck started to make all kinds of noises, the steering wheel started shaking uncontrollably, and i completely lost all acceleration. fortunately for myself and my family, i was able to steer the car out of any immediate danger and bring the car to a stop on the shoulder because of my quick reactions. my family and i were stranded on the highway with no means of transportation. this was a very traumatic experience for all of us. i was able to call another family member to come and pick up my family, but i had to stay with the truck until i was able to have it towed to my house. after doing a little research, i learned of this faulty nissan design problem and was advised to contact the nhtsa because they have an open investigation into this type of occurrence. i am pleading with you to seriously look into this problem before anyone has to lose their life or face a permanent disability resulting from this type of occurrence. i hope that the nhtsa can complete this investigation soon. i would strongly recommend a recall for this safety hazard and potential life threatening occurrence that is a direct result of nissan's faulty design, which they are completely aware of, but deny taking any responsibility! *tr

The radiator leaked fluid into the transmission and cause a complete and total loss of both. a lawsuit was filed and settled by nissan without them taking any responsibility for their faulty design. i guess this won't get noticed until people start dying from nissan's defective design. when that does happen, nissan will just payoff the families so this whole issue just goes away! *tr

At 60mph and also 40mph the vehicle vibrates heavily and is slow to react to power inputs with no warning signs prior. this was determined to be caused by the known defect related to the radiator / heat exchanger, where the engine coolant mixes with the transmission fluid and gets into the transmission. this then turns into a "pink milkshake" consistency fluid and completely ruins the entire transmission and valve assembly. this requires a complete rebuild or replacement of the transmission and radiator to correct the issue. there is no warning sign and this affects these vehicles at different rates. this can cause cars to seize up unexpectedly in the middle of driving creating a dangerous situation. since this is a known issue for nissan trucks model year 2005 - 2010 this should be a safety recall. it is not a matter of if this will happen, it is a matter of when. in my personal situation i had no injury or immediate car shutdown, however i would have no warning if that did occur and has the potential to be dangerous, especially at highway speeds. this has to be investigated and is uncalled for to have a known defect and not disclose this to owners of these vehicles. additionally, there is a perfectly good way to mitigate this issue by adding a dedicated cooler for the transmission and bypass the radiator, which is a cheap and easy fix to never have this issue. *tr

Problem with radiator fluid leaking into the transmission, which has now damaged the transmission. since nissan won't do the right thing and we're beyond the 80,000 miles, we're stuck paying for a new radiator and transmission. instead of getting away with doing nothing except for extending the warranty, nissan should have been required to notify all affected people regarding the exact problem and issued a recall and pay for a new radiator. this obviously is still an issue for alot people and probably many, many more in the future, long after the so-called proposed settlement. too the nhtsa! please investigate and require nissan do the right thing! *tr

Radiator cracked causing coolant to mix with transmission fluid. *tr

Failed transmission cooler-engine jerks at speeds 40 mph and higher. *tr

My transmission stopped shifting, i took it to a transmission shop an was told my atf line that runs through an engine coolant chamber in the radiator failed and get radiator fluid in my transmission and that my transmission needs to be replaced/rebuilt. now i am stranded with out a vehicle when my vehicle only has 85000 miles on it and has had regular maintenance work on it. i am extremely disappointed and i would like to see nissan step up and be held responsible for an issue that is accruing because of faulty factory parts. *tr

First noticed a stuttering when driving and a clunking sound when moving the shifter from park to reverse to drive in february. also experienced no heat and over heating in march. upon repair of thermostat, draining the radiator showed an accumulation of thick grey gunk in the coolant. thermostat seal itself was melted. had dealer evaluate clunking sound and they diagnosed it as intermix (the problem identified by the coolant) a manufacturing defect in the radiator/transmission cooling components that allows the coolant to contaminate the transmission fluid causing transmission damage. as a result of class action lawsuit, dealership explained that mileage was over the nissan warranty limit of 100,000 even though the problem did not manifest until almost 120,000 miles. recommended fix was in stages - 1) replace radiator and transmission flush $1200++ 2) if problem is not solved, replace transmission $4000++ have talked with nissan corporate to no avail. case # is [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6) *js

Transmission failure in my 07 nissan xterra. a complete loss of motive power and needed to be towed. the dealer diagnosed the problem as a failed transmission fluid cooler located in the radiator assembly that allowed coolant to mix with and contaminate the automatic transmission fluid, resulting in damaged internal transmission components and a damaged internal transmission computer. was told that this is a huge problem with these vehicles and the nissan corporation is well aware of this problem. *tr

While driving, it would feel/sound like i ran over the speed bumps on the side of the interstate. the vehicle then started jerking into gear. we immediately started looking on the internet for possible problems, the only one that we came up with was the transmission/coolant issue. we took the vehicle to nissan and was told that it was not under warranty and would cost $6,000 to fix. since there was no recall we would be buying another faulty transmission/coolant and could happen again. this is not a normal wear and tear problem from what we have been reading, but a faulty design. we called nissan and made a complaint with them and was told that there was nothing they could do. my vehicle started overheating today 4/7/14 and when we checked the coolant, it is the consistency of a milkshake. if nissan stood behind their product they would do a recall and get this problem fixed. we are probably going to have to get a loan to get this fixed since we have not been able to save the money up and the problem is getting worse. it's just a shame that when we do get this fixed we are buying another faulty transmission. it's a lose/lose situation. we thought about trading in and getting a newer vehicle but would be upside down on our purchase. very dissatisfied customer! *tr

Internal leakage of engine coolant in to transmission. *tr

My cars coolant gage jumped straight to h out of nowhere. after pulling into a shell station for antifreeze, it was apparent what had happened. there was something mixed in with the antifreeze. it was the transmission fluid. after being told i would need a new transmission and radiator, i started researching and im not the only one dealing with an otherwise great body you can't do anything with and doubt i will be the last. after further research it appears that no recall has been approved and i believe there are many of us wondering why? this is a consistent problem with hundreds of cars and it's not even one make, it's many. 3 in my category. does a recall only happen when it has fatality attached? this is a faulty system and nissan approved these coolants in the transmissions and continued to even after complaints of the system. i was lucky to catch mine right away but still need $3000 to fix it! it won't be long until fatality is attached once someone's transmission goes out on a highway or in 5 o'clock traffic! nissan needs to issue a recall!!! *tr

I have a 2007 nissan xterra with a common issue...the faulty radiator leaks into the transmission causing transmission failure. this can cause the transmission to seize up leaving a moving car to lose speed rapidly which is an unsafe situation. this has not happened to me yet as i caught the issue and am fighting with nissan for them to fix defect..until then i am stuck with this as my car. great. nissan has asked me to pay a $3k "co-pay" to share in fixing the fault... *tr

Radiator cracked leaking coolant into the transmission. *tr

The first time i noticed something wrong with the transmission, the vehicle would make a large vibrating sound at random times. this would keep getting worse until i had to bring it to a shop, overall just about a week. i was told the transmission and radiator fluids were mixing and that i needed a fluid flush a long with a new radiator. about 6 months later, my car just wouldn't start one morning. i take it to the shop again, hoping it is just a minor fix this time. this time there is something wrong with the transmission and computer system. luckily i wasn't driving when this happened, otherwise who knows what damage it would have caused to the car or to me. *js

I have a 2007 nissan xterra which started to "stutter" and hesitate when pressing the gas. the car almost felt like it was shutting off while on i-4 highway. the shuts down and wont start. i had the car checking and found out that there was a crack in my radiator and that the fluid had leaked over into the transmission. i had the radiator replaced, a few months later, transmission is still not working. i took the car to nissan, they told me i would have to replace the whole transmission which would run about $5200. i called the nissan headquarters and was told that there was nothing they could do because my truck was at 109,000 miles. *tr

Our 2007 nissan xterra, purchased brand new, began to overheat. upon checking the fluids i noticed the coolant level was dangerously low. i was certainly puzzled where the fluid had gone because there has never been any visible leaks or any warning lights or any other symptom to draw my attention. i began to look into the situation because i was puzzled and quickly learned of the massive number of nissan owners experiencing the same problem. sadly, i was now one of those victims. yes, the coolant had contaminated the transmission fluid via the faulty transmission cooler. there is a class action lawsuit that i am sure you are aware of but i was unaware of. i do not recall any contact notifying me of a class action lawsuit and the potential damage. i had no reason for worry because my vehicle had not given me any trouble signs and the fluids have always checked normal during normal service checks. like many, i cannot afford to shell out the dollars that this negligence on nissan corporation behalf has caused. i encourage you to please force nissan corporation to issue a recall requiring them to make all the appropriate repairs for these damages. please, do not put a cap on the mileage or set the mileage relatively high if you must. my vehicle has only 89,000 miles and only gave signs of damage less than 500 miles ago. *tr

Sudden loud noises/banging while driving. pulled over, had vehicle towed to mechanic. radiator found to be cracked. radiator fluid leaked into and contaminated transmission causing sudden transmission failure. learned nissan was/is aware of this problem and has not notified anyone of preventative measures to prevent failure of transmission. "extended warranty" resulting from class action lawsuit requires $3000 copy for vehicles with 90,000-100,000 miles. my mechanic says this is a joke because radiators not cracking until at least this time. now i have to pay $3000 i don't have to repair the transmission which i could have saved had i been notified to replace the radiator. i will not ever purchase a nissan again. *tr

Radiator leaked into transmission just after 100,000 miles. so why didn't nissan tell us this was going to happen? *tr

My car was jarring and making a rumbling noise so i took it in to get fixed. there was water detected in my transmission so i had it flushed twice. the rumbling continued so they replaced the radiator. that cost a total of about $1,000. a few weeks later it got worse and they told me i needed a new transmission. that will be between $4500-$5000. nissan has been under investigation regarding coolant mixing in the transmission fluid and have not done anything to fix the problem. there to be a recall! *tr

The radiator leaked and the coolant went into the transmission and now has totally screwed up the transmission to the point of having to replace it and the radiator. nissan knows about this problem and will not make a recall on either parts which is completely wrong. *tr

Radiator leak to transmission. *tr

Tl* the contact owns 2007 nissan xterra. the contact stated the engine light illuminated. the vehicle was taken to the dealer to have a diagnostic test performed. the failure was located in the transmission where the radiator fluid was mixed with the transmission fluid. the transmission and the radiator needed to be replaced. the manufacturer advised the vehicle exceeded the 100,000 miles warranty repair. the vehicle was not repaired. the failure and current mileage was 102,000.

At varying speeds above 45mph the vehicle will shudder as if you were driving on a rumble strip. this can be startling as there is no indication of when or where it will occur. when the radiator failed our mechanic informed us that the transmission was destroyed because of design of the radiator and transmission cooling lines, which allowed coolant to seep into the transmission fluid thus destroying the transmission.. *tr

My radiator went out in the starbucks drive-thru. i had it towed to a shop & was told it is a known design flaw by nissan where the fluids are mixing & the only thing i can do now is replace the radiator & "hope" the fluids did not go into the transmission. got the new radiator & had a trans flush 3 times & paid about $1800. it is now a month later & my service engine light is on. today, i am told i need a new transmission which will cost $3800. this is our only car. we do not have the funds to pay for a new transmission. for safety reasons, we urge you to please issue a recall on this poor design by nissan where the fluids are mixing & causing safety concerns to the consumers. *tr
