This pathfinder is experiencing a failure with the transmission oil cooler / radiator assembly and is within the 10 year period specified by the extended warranty but is beyond the 100,000 mile limit. Due to the nature of this defect, the severity of this failure, the repetitive nature of the failures and the limited or missing failure warning signs, I believe that an investigation is warranted. Extending a warranty for a short period of time a limited mileage that most consumers breeze through in a few years in order to avoid a recall is not good for repeat business or safety. Nissan settled a class action lawsuit where it identified the defective radiator, but capped the warranty at 10 years/100,000 miles. Whether or not the incident happened at 10,000 miles, or 200,000 miles, it is still a manufacture defect, not caused by the consumer. Simply extending the warranty coverage for the radiator without warning consumers of the consequences to the transmission only makes sense to me if nissan is looking to cut their losses. Why didn't nissan warn consumers that the transmission could fail very quickly as a result of a cracked cooler tube? How many consumers must needlessly suffer transmission failures in busy intersections and on busy, congested highways before nissan does the ethical thing and issues a safety recall? This defect need not be left on the consumer's shoulders, and could very easily cause safety issues for the owner.
2007 Nissan Pathfinder engine complaints
Page 7 of 9: complaints 161 to 190 of 242, newest first, as owners wrote them.
Vehicle would not start. After examining what may be the problem it was found that the engine coolant and transmission fluid had mixed due to a defective oil cooler inside the radiator that caused the valve body in the transmission to fail that controls starting and transmission shifts. Vehicle was towed by transmission shop for a compete overhaul including a new valve body. Cost of repairs total was 3074.00 dollars. Transmission shop installed an external transmission cooler and stated they were having to make these repairs on a number of these nissans for this defect.
Dealership states that transmission needs to be replaced as well as radiator due to manufacture defect. Repair not allowed under warranty due to mileage. Told that repair would be $10,000.
Car loses power, shutters, has high RPM without acceleration, skips gears, stalls. Had radiator replaced ($1,200), but didn't solve the problem. Was told a new transmission is needed due to coolant mixing with transmission fluid and damaging transmission and components ($4,500).
About 2 weeks ago I was driving my 2007 nissan pathfinder (automatic), when I try to accelerate a bit the vehicle show signs that the speed-gear will not shift properly. When I am at a red light also for example once the light change to green the car take a few seconds to accelerate to the proper speed making it an inconvenience for other cars behind me since the speed will not pick up on time. Sometimes also it tend to " shot" making a weird not before resuming proper speed and this happen mostly on local roads.
Tl* the contact owns a 2007 nissan pathfinder. The contact stated that while driving approximately 50 MPH, there was an unexpected increase in acceleration for several seconds. In addition, the engine rpms increased. The contact also stated that the vehicle had sporadically decelerated independently with an abnormal reduction in engine rpms. The failure recurred numerous times. The vehicle was taken an authorized dealer, who stated that the radiator and transmission would need to be replaced. The vehicle was not repaired. The manufacturer was notified of the defect. The approximate failure mileage was 110,669.
2007 nissan pathfinder with 86k miles. Vehicle began hesitating when traveling 40 MPH on highway, then loss of power sometimes. The car began to overheat. Took it to a mechanic who told me that it was the transmission and radiator. Cooler line had failed and mixed with transmission. I called nissan and was told that they extended the warranty to 100k but I would have to pay $2500 out of pocket. Learned of a class action lawsuit in 2012. Nissan never notified me of the transmission problem. If they had notified me on time, I would still be under the 80k warranty. I have no money to fix my car and now I'm stuck paying for a car that I can't drive.
2007 nissan pathfinder le - 92,000 miles est. - I bought this vehicle new in 2007 and have been very pleased up until the past two weeks. My story is the same as others - transmission started getting rough, particularly around 45-50 MPH and on inclines. There is an audible and jolting clunk moving from neutral to drive. While driving in the above range, the vehicle sounds just like driving over a rumble strip on the highway. I haven't even taken the vehicle in to the dealership yet, and I already know what the problem is. This car has been babied for years being that it is the sole automobile that my wife and kids drive in. I'll be [xxx] if I'm going to pay a $3000 deductible for a defect that nissan has had full knowledge of for years now! To[xxx] with the settlement that left most of us out in the cold while padding the pockets of the attorneys! It is time for the federal safety agency to step up and make the only right and safe decision that nissan refuses to make! These cars are not safe to drive on the road in this condition! Mine will remained parked in the drive until nissan is forced to recall every vehicle with these faulty radiator/transmission issues. This is my complaint. I hope that nissan does the smart thing here. They have lost me as a customer for life, and I've owned or driven over a dozen nissans in my time. It's a shame that this company will sit back and let these complaints mount up until truly forced to do something about it. They should be disgraced knowing that right now there are mothers & children driving in vehicles that could suffer complete transmission failure at any point leading to injury and death. My advice to all is to bring this to their doorstep. Technology offers us the ability to bring the fight to the top of the food chain. I'll be bombarding email addresses and voicemail boxes until this is resolved. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
Radiator failed, leaking antifreeze into transmission. This mixing of antifreeze and transmission fluid caused transmission to fail. The violent vibrations and rough shifting is a safety hazard and nissan should recall all models with this radiator. I had to pay $2500.00 to have this defect repaired.
My vehicle was shifting weird when all of a sudden it violently lurched forward while in traffic. I took it to the transmission repair shop and was notified that my transmission had coolant in it and needed to be replaced. This will cost over $9,000 to repair and the safety issue is that the vehicle lurching forward so violently is unacceptable because of the faulty transmission cooler etc...
The automatic transmission in the vehicle began to shift roughly. It was determined through the nissan dealership that the radiator had a crack in , and radiator fluid was leaking into the transmission fluid. It is a design flaw.
My nissan pathfinder radiator coolant leaked into the transmission, I got an extend warranty and now the extended warranty is not covering it due to radiator coolant leaked to the transmission and it not a cover benefit now I'm screw.
Tl* the contact owns a 2007 nissan pathfinder. The contact stated that when driving over 45 MPH, the vehicle would hesitant upon acceleration. The vehicle was taken to the dealer for diagnosis. The technician stated that the radiator was leaking fluid into the transmission. The technician stated that the radiator and the transmission would have to be replaced. The manufacturer was not made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 150,000.
The radiator and transmission has appeared to fail in my nissan the radiator started to leak several months ago and I finally had to replace the radiator and now the transmission has started fail. The car has been well cared for and both the radiator and the transmission appear to be failing well before a normal radiator and transmission should.
Vehicle's transmission started slipping at certain speeds. Got a trans flush hoping it would improve. Problem returned. Service engine light came on. Took to garage and had a new wiring harness put on. Problem returned. Got stranded and had vehicle towed. Determined that coolant was in the transmission fluid. Huge repair bill. Part of the class action suit now but am still out $2500. Probably started occurring before 80,000 miles and had I been more investigative at that time, bill would have been covered because it was under 80,000. Now it's over that amount and I am out of luck. Huge disappointment in nissan!
Transmission starting slipping then started jerking while driving then it started overheating. Took it to a nissan dealership because I bought the extended warranty that was supposed to cover the powertrain. They told me that the cooler cracked which caused the radiator fluid to leak into the tranmission and messed up the radiator, which is not covered by the powertrain warranty because the radiator cooler was not part of it. The dealership wants to charge over $6000 to fix it.
Transmission failure while driving in traffic. Caused by ruptured coolant line, coolant mixed with atf. Replaced radiator and flushed transmission, but damage was already done.
We noticed the nissan starting to jerk on the frwy and service engine light came on. Took it immediately to the mechanic they gave me bad news appearantly the transmission had radiator fluid in it. He said he had seen this problem before many times his exact word were the way nissan designed this particular vehicle causes this. My mechanic had to replace radiator flush the whole system put new fluids in total cost $976.oo he advised me to take it to a transmission shop because he said it needed to be looked at by a specialist since he could not guarantee it would not happen again or if even the transmssion would work. Well it worked but the service engine light came on on the way to the transmission shop once they got done with it and replaced everythin that needed to be fixed on the inside of the transmission I paid $3227.49. According to everything I read this can hapen to the pathfinder without any prior problems. We took pretty good care of ours was a great vehicle till we had to dish out almost 5k after we had just paid it off. I will never buy nissan again!
After a 90k mile check-up and full service in spring 2012, I understood that my pathfinder was running well. Never was there a mention of issues with the radiator / transmission, nor was the connection between these elements replaced to prevent an issue (to my knowledge.) at 101k miles, the heat went out in the rear section of the car (I did not realize this until two months had gone by and I was arguing with my freezing child in the back seat that I had his heat as hot as it would go - he was clearly correct and the rear blowers were blasting him with icy air.) there was a "clunk" upon shifting the car into reverse, and between 40 and 60 MPH the transmission lagged and sounded like it was grinding and working hard. At 106k I brought the pathfinder to the nissan dealer where I had originally purchased the car. This was the same dealer who had done the 90k service, as well. They determined that the radiator fluid had mixed with the transmission fluid and that my car needed both a new radiator and transmission for $9,000.00. (my truck is maybe worth $15,000 at this point - really?) after deliberating with the service supervisor, he offered an alternate option of only changing the radiator and flushing the transmission several times to eliminate the contaminated fluid. I gave the ok for this service option at $600. Since the service, my transmission is still lagging between 40 and 60 MPH and the "clunk" still happens during a slow reverse. I am now investigating my options for a new transmission as the vehicle is still in beautiful shape, other than its engine issues. It is my belief that this issue is wide-spread enough that the transmissions and radiator should be recalled and replaced by nissan - or paid for by nissan since it's their faulty parts that cause the problem.
While driving on street around 2 pm, the car just lost its power and I end up stuck in the middle of the street with my 2 kids at the back seats, the car wont moved and I need to call for help so the other driver helped me push the car on the side of the street. Tow truck arrived and towed my car to the nearest shop and found out that it was the transmission mixed with water coming from the radiator. It cost 2800 for everything. The current miles when this incidents happened is 111200.
There is a known defect in the radiator/radiator coolers in the '05, '06 and '07 nissan pathfinders which causes the radiator and the transmission to fail. Please help with a recall on this problem, several of the folks still have a payment on the vehicles. You can see all of the problems that folks are having. Thanks, terry please try to do all you can for all of us, I can't see that nissan can get by with this. They are just to replace the defect parts.
The radiator fluid is leaking into the transmission fluid and causing significant "rumbling" noises. The vehicle does not shift correctly.
The fuel gauge stopped working over a year and a half ago. When we contacted the dealer they never told us about the extended warranty. They quoted a price that we, a military family could not afford,and that was it. Then last year, a shuddering began. We took it to the dealer and spent almost $800. They flushed the transmission, but the shuddering only got worse. When I took the car in they informed me that the radiator fluid leaked into the transmission and now both need to be replaced. I called nissan and they basically said that its my problem!! I have been in tears since. My husband is in afghanistan fighting for his country. He worked hard and paid the car off 2 months ago and now this. He is so worried about us being stranded when his focus should be on what's happening there. We don't have $8000 to spend on a car that we just paid off and that should be in top form.
When slowing down or speeding up between about 30-50 MPH, the vehicle transmission felt like it was slipping. After much research and several hundred dollars of work come to find out that the radiator is faulty causing cross-contamination between engine coolant and transmission fluid. I am aware there is an ongoing investigation into this matter as well as a class action law suit pending. I have spent significant money to troubleshoot and replace what was needed (radiator and multiple transmission flushes) and feel I should be reimbursed as well as have a more thorough inspection and additional repair/replacement if needed. I am concerned that the engine is now damaged due to transmission fluid being in there and possibly the transmission. Both of which may be future problems that materialize down the road. Something should be done to make this right for the many nissan customers.
I bought a 2007 pathfinder from a very reputable used car business, carmax almost 3 years ago. They are very well known in the area for thoroughly checking their vehicles before reselling. It had approx 59k miles on it and I've loved it until recently. I started experiencing heating problems awhile ago but my mechanic couldn't find anything wrong - he even checked the radiator. A few months ago, the transmission would shudder occasionally when I reached about 40 MPH. At first it was very minor, I actually thought it was maybe grooves in the road, etc but the issue got worse. I brought it to the dealer and was told I need a new radiator and transmission - this is a widespread problem. I was also told flushing the transmission probably wouldn't help. The radiator is going to cost me $913 and because this is such a widespread problem, a new transmission was the only thing they could find at $7400! I still owe on this vehicle and am wondering how will I ever trade this in or even afford to fix it. Nissan won't help in any way, even by discounting the labor and parts and the class action settlement won't help either because my pathfinder has 109k miles on it - 9k over the extended warranty nissan issued. What a disaster. I'm a single mom with a young daughter and a mother I care for. I recently took my family to visit my sister in west virginia, you know - mountains. Imagine if something would've happened then. I had no idea all of this was going on and am now terrified to drive it. I've never received notification from nissan that there was a potential issue - I would've brought it to the dealer immediately and been covered for repairs!!! This is a nightmare and nissan should be held responsible in some way. Why aren't they standing behind their product at all!! Do a couple of hundred people have to get hurt before something is done?
I took my 2007 nissan pathfinder to the dealer to have the brakes worked on and while there they performed a multi point vehicle inspection. From this inspection they informed me that there was cross contamination of the coolant and transmission fluid due to a failed transmission cooler. They indicated that damage had already started and it would only be a short time before the transmission failed completely so I needed to replace the radiator and transmission under the extended warranty and there would be a $3,000 deductible cost. In talking with the dealership service personnel and researching online it is clear that this is a common problem and obviously a design failure which could be a safety issue if the transmission fails while driving due to this known problem. My family and I are thankful that just by chance the brakes needed work otherwise my wife and kids could have been driving and been at risk of potential injury if the transmission failed unexpectedly as has been reported by other nissan pathfinder vehicle owners. Due to the number of failures that has occurred it is irresponsible for nissan to just extend the warranty instead of taking a proactive approach and actually notifying their customers of the problem and fixing the known problem under a voluntary recall. I urge the federal safety agency to initiate an investigation and hold nissan responsible for their design failure and protect the public from the potential safety risk by forcing a mandatory recall to fix the problem instead of just waiting for failure which puts the consumer at risk.
My wife was driving home from picking up our children from school. She was traveling approx 65 MPH when the vehicle lost power, became unstable, and would not accelerate. She said that it was like someone put on the emergency brake with five times more. Force than normal almost causing her to loose control of the vehicle. Upon taking the vehicle to a repair shop the problem was found to be that coolant had leaked into the transmission and had destroyed the transmission computer and the transmission.
At 35,500 miles the secondary timing chain tensioner shoes failed. The dealer told me that this is a very common problem with the 4.0l motor. This repair is $1000 and not covered by any remaining warranty. I believe that since thousands of people have had to pay thousands of dollars to repair this defective part it should be a recall. This would be dangerous if this failed while the vehicle was moving at highway speeds, luckily I was driving slow enough to avoid an accident.
The radiator leaked fluid into the transmission cause damage to the transmission rendering it useless. This is a known design defect with the 2007 nissan.
