Was told that radiator coolant was mixing with my transmission fluid. I noticed first that the heater wasn't getting very hot a few months ago, but since I live in texas, this wasn't a huge deal for me since it's not that cold and so I was going to have it serviced at my next regular oil change. However, then just a couple of days ago, I noticed that the car would shudder around 45 - 50 MPH so I took it in immediately and was told that I was experiencing a known defect of nissan's built between 2005 - 2010. If I had known about 3 months ago (about the time I started noticing the heater issue) I would've been fully covered under their extended warranty of 80,000 miles for this particular defect. But I'm at 84,000 and therefore have to pay $2500 out of pocket for a new transmission and radiator. I feel that I should still be covered since I started experiencing issues before 80,000 miles but I had no idea that it would be such a huge problem that would require a new transmission and radiator on a car that is only 7 years old...
2007 Nissan Pathfinder engine complaints
Page 8 of 9: complaints 191 to 220 of 242, newest first, as owners wrote them.
Transmission began shuttering, not up shifting and limited acceleration and speed on freeway at 55mph. Turns out that the transmission oil cooler lines had been leaking anti-freeze into transmission and destroyed it. Manufacturer has replaced with same cooler and rebuilt (not new) transmission. Issue still exists intermittently. Needs recall enforced. Manufacturer is pricing same cooler and rebuilt transmission at over $7000. Then agreeing to only charge $2500 - $3000 per class action settlement. Outside independent repairs quoted at $350 for cooler and less than $2000 for rebuilt transmission. Gov.'t recall should cover all new and re-designed parts. Failures will and are occurring again. Can result in accident at high speeds.
Tl* the contact owns a 2007 nissan pathfinder. The contact was driving 50 MPH when the transmission began to jerk without any warning. The vehicle was driven to a safe location and inspected. The vehicle was taken to an independent mechanic who advised that the radiator coolant leaked into the transmission fluid, which contributed to the internal damage of the transmission. The vehicle was not repaired. The manufacturer was notified of the problem. The approximate failure was 110,000.
Left motel at 7am, vehicle seemed to have trouble shifting, high RPM..pulled over to check..would not start..towed to dealership. *tr the consumer stated the radiator failed. Updated ivoq 01/14/13
Transmission failure from radiator fluid leakage into the transmission fluid. The cooling system for the transmission runs through the radiator. When the radiator fails radiator fluid leaks into the tranny fluid and destroys the internal transmission clutch plates and torque converter. Nissan extended the warranty from 36k to 80k miles or 8 years on the radiator, knowing there was a problem, but no notice from them to owners of this problem. When the problem starts, it is too late, resulting in $6800 - $7500 in personal expenses to replace the transmission and radiator. Nissan will not consider fixing after 80k miles. I have 127000 and only 5 years old vehicle. This problem was acknowledged to affect 2005 - 2010 pathfinders. There are hundreds of complaints on this issue on forums, which I find after I have the problem. Nissan should recall the radiators and fix the problems. It is a defective $300 radiator that damages a $7000 transmission!... This is unfortunate and irresponsible for nissan and is basically a band-aid on a serious hazard. Now my $30,000 vehicle is worth $3,000 to the dealer for trade in.
Pathfinder started hesitating at 40 MPH regardless of city or highway driving, had transmission fluid changed and was advised by my mechanic there is a leak from radiator into transmission line, have since then seen transmission fluid a milky color and I cannot drive vehicle with overdrive on, when it drove with od on at about 40 MPH there is no shifting of gears.
While driving I noticed a grinding sound when I reached speeds of 40-45 MPH. When I pulled in to park the vehicle there was a loud grind and then the vehicle would not start. After checking the fluid levels I found that the engine coolant and the transmission fluid were mixing.
Tl* the contact owns a 2007 nissan pathfinder. While driving approximately 55 MPH, the vehicle began stalled while the contact was attempting to accelerate. The vehicle was taken to the dealer for diagnostic testing. The technician advised that the valve body and radiator needed to be replaced due to a leak in the radiator and the coolant was intermixing with the transmission fluid. The manufacturer was made aware of the failure and advised the contact that the vehicle was not included in any recall. The vehicle was not repaired. The failure mileage was 101,000 and the current mileage was 104,000.
First issue started while trying to accelerate onto the interstate. The car/engine started shaking between 40 and 50 MPH and would not accelerate. I was nearly rear-ended when I had to merge into traffic. Other issues were similar, car shaking at 40 to 50mph, like driving over a washed out road. Unable to accelerate initially, this would last for several seconds, before finally responding, shaking would go away when speed would exceed 50mph. Final safety issue occurred when accelerating after a stop light onto a highway ramp. At 40mph the transmission completely went out, the car would not shift into gear and would not accelerate. I had just started to merge, I had to swerve back onto the ramp lane and stop in the middle of the road. I was nearly hit by the highway traffic and almost rear-ended by a car going back into the ramp lane. Cars were forced to slam there brakes to avoid hitting my dead car, it also made it very difficult for other cars to merge onto the highway, several cars narrowly avoided an accident. Car was taken to shop, transmission and radiator had to be replaced. Radiator defect had caused the transmission to fail.
It was november 2011, I was driving my nissan 2007 at that time I was 9 months pregnant. My daughter who was 5 years old was with me. I was entering the freeway when my car started to shake,make noises and it started to slowdown on its own. I presses the speeding pedal but it kept loosing power. My daughter was crying because she was scare. I was crying too I did not know what to do I was in a dangerous situation because it happen when traffic was at its pick. I could not stop because cars where behind me and I could not speed because my car was loosing power and it smell like something was burning. I manage to get off the freeway with the emergency lights and stop the car at the moment the car die(no power). A tow truck had to take as home. Nissan would not fix the problem because of the miles/warranty whichever comes first rule that they have. They would fixed for a lot of money anyway I took it to a shop an I was told it was the radiator which damage the transmission. I had it repair and a few days latter all the emergency lights on the car turn on and went crazy and the car stop at ones this time it was the gas tank. It scare me so much that I call my husband and told him, "this car is going to kill me and my children" nissan pathfinder is dangerous and something must be done or someone is going to get kill. It is a safety issue please help us. Do something we need help pathfinders are dangerous nissan won't fix this factory problem with out getting pay. Please a recall needs to get done. I beg you do something this is the USA or not? I know at list 3 more people that had the same problems with this cars and all the mechanics agree that it is a factory problem. I will never buy a nissan it is a lemon! First radiator linkage then liquid in transmission then replace transmission than it will be the gas tank what is next?
While driving on the highway, I felt my transmission seem to shift very roughly into overdrive, and usually occurred between 40 and 50 MPH. Over the course of about a year, it continued the behavior off and on, until it began to do it daily and I took it to the shop. It was diagnosed as having had antifreeze leak into the transmission due to the oil cooler lines cracking, a common problem with nissan pathfinders, and other nissan vehicles of my model year. There was metal in the transmission pan which signifies that a rebuild is inevitable, all due to the mixing of antifreeze in the transmission. The radiator must also be replaced due to the mixing of transmission fluid, as the mechanics found the "milky" substance, typically associated with the mixing of water and transmission fluid in the radiator. So far, I have been quoted approximately 6,300 dollars for a repair job on this vehicle.
Tl* the contact owns a 2007 nissan pathfinder. The contact stated that while driving 45 MPH, the vehicle began to jerk and shimmy abnormally. The vehicle was taken to an independent mechanic for diagnosis and the contact was informed that the radiator malfunctioned and leaked anti-freeze into the transmission. The vehicle was taken to a dealer for diagnosis where they also advised that the radiator failed and was leaking anti-freeze into the transmission. The manufacturer was notified but offered no assistance. The vehicle had not been repaired. The failure and current mileages was 122,123.
2007 nissan pathfinder radiator defect causing leak of coolant into transmission fluid and resulting in transmission/radiator complete damage, undetected by dealer service for 30,000 miles. Problem detected with opening of investigation. Nissan requires co-pay of $2,500 even though complaints occurred previous to 80k miles and when problem detected, was 414 miles over requiring a significant amount of money for a known defect.
I was driving at 30 MPH and the nissan pathfinder 2007 start making a noise in the motor like when you have the car in 1 but it was on drive, then the service engine soon alarm appear. I parked the car but when turning on again it didn't. The dealer said that the radiator coolant damage transmission and the computer because was damaged. The estimated cost of the repair was $9,400.
I started having a sudden jerking in my 2007 nissan pathfinder when driving down the highway. When I took it into a nissan dealer they diagnosed the problem as a failure with the radiator internally and externally which allowed leaking coolant into my transmission fluid causing both radiator and transmission failure. The dealer now states that I need to replace both items or trade it in. .... Come on nissan you have a major problem. We need a recall.......
Radiator defect leaked coolant into the transmission caused transmission to fail; will need a new radiator and transmission because of this known defect in the radiator. Also, engine timing chain defects in 2005-2010 pathfinders. Repairs are set to be $12,000 - which is more than the value of the vehicle.
I was driving on the freeway when all of a sudden I heard a thud and lost power, had to go over 2 lanes without being hit.... I took it to the shop and the mechanic new excactly what the problems was. Radiotor fluid getting into the transmission causing it to fail... Hundreds of nissan pathfinder owners are having this problem. Tell nissan to recall this now before someone gets killed.. Shouldnt have to pay $8000 for nissans crappy work..
My pathfinder was should have been slowing from the speed of as I was braking and letting off the gas, but it kept moving forward and shaking. If there was a car in front of me I would have hit them hard. My transmission would not shift down to slow down, due to radiator leaking into transmission. The cost of my repair of both radiator and transmission is over $5000.
2007 nissan pathfinder. Consumer writes in regards to transmission and radiator problems *tgw the consumer stated the repairs totaled $ 3,399.10. *jb updated 11/05/12
My wife was driving my 8th grade son and his basketball team to middle school game. She was on the freeway going 65 MPH, when she felt the car jerk and then start to lose speed, the engine was still running but the car had slipped out of gear. She had no power and luckily she had room to coast to the shoulder. We took the car to the dealer the next day they diagnosed the problem as transmission failure due to radiator fluid in the transmission. We replaced the radiator and coolant lines and flushed the transmission, and it ran fine for a few months. But the check engine light came back on last month, we took it in and now they tell us that we have to replace the transmission. Please investigate this issue with the nissan pathfinder, frontier and xterra. It seems to be more and more of a common issue with nissan owners and nissan is not doing anything to repair this very serious and costly problem. I just got an estimate on tuesday (9/4/12) for $9459.00 worth of repairs to the transmission and the radiator. I bought the car new from nissan, and it now has 110,502 miles.
While driving down the highway my husband and I experienced loss of power and had to pull onto the side of the road. We were towed from there to the mechanic who explained to us that the internal radiator had leaked fluid into the transmission causing failure to both. Since our warranty was outdated we are now out 6000$ and are struggling to fix this. I am very frustrated and disappointed in the vehicle. We had our children with and I am very glad that we were not at a busy intersection or interstate.
Wife first noticed a vibration on her way home from school with our daughters. Became progressively worse over time. I had tires, bearings, etc checked. No problems found with any of those. Looked online and discovered that a lot of pathfinder owners were having transmission problems. Checked coolant and found that it had in fact mixed with transmission fluid. I switched the lines from the transmission to trans cooler and radiator to prevent further contamination, and flushed radiator/replaced coolant. Also had transmission flushed/fluid changed. The vibration is still present, as I don't have $5000 + for a new transmission/radiator.
Start having problems in mid july of 2010. Transmission was jerking in gear. Radiator broke down, allowing fluid to leak into the transmission. Vehicle is inoperable. Also been having problem with fuel gauge. Unable to get vehicle repaired, due to limited income. Vehicle became inoperable passed extended warranty.
I have maintained my car. In june, my nissan dealership charged me $1500 after I reported a jolt in the transmission. I brought it back 08/10/2012 and they said the transmission needed replaced. I took it to another shop and they said the radiator fluid had leaked into the transmission and ruined the transmission presenting a financial burden and a huge safety issue. *tr updated 09/13/12
I understand now that nissan pathfinder owner (05-07) have experienced issues with the transmission failing due to defective parts. I now have to have my transmission and radiator replaced to the tune of $7000+. Why has there been no recall for this problem?
At first started noticing hesitation in transmission at 40 MPH, confirmed by 2 mechanics trans fluid is milky color and changed fluid at a local service station that had to go to nissan and get their transmission fluid to finish job. Now back to milky transmission fluid, have to take overdrive off because gears will not shift, I also carry gallon of water because at any time radiator fluid levels can be low; have to turn air off at long stop lights so temp gauge doesn't go up.
While driving with the AC on, my vehicle started to blast out hot air through the vents and overheat. My car has never ran hot before, I haven't had any problems since I've had it. I was able to pull over safely and let the car cool down. My husband removed the radiator cap and noticed a milky liquid in the radiator. We had to have the vehicle towed to a mechanic shop and they notified us of the recall on the nissan (2005-2010 models) radiators. They said that it was a common problem that they have been seeing where the coolant mixes with the transmission fluids and cause a major repair problem. We have been told that the radiator, transmission, transmission kit, throttle, vial body, and torque converter will have to be replaced. I feel petrified to know that nissan knew about this existing problem but refused to have these issues repaired rather than taking the easy way out and extending the warranty. We bought our truck brand new from the nissan dealership and we also paid for the 5yr/100,000 mile warranty. I have had my truck for 5 yrs and 2 mths, something should have been done about this. We the consumers have trusted this brand for many years and we depend on our vehicles on a daily bases. My family and I were all in the vehicle when the incident happened we could have been seriously harmed in a high risk situation. We had the 90,000 mileage maintenance completed where they flushed the radiator, changed the transmission, & etc. And everything was fine. My husband have always taken my car in for timely maintenance and no one has ever mentioned the radiator issues.
Tl* the contact owns a 2007 nissan pahtfinder. The contact stated that while driving 40 MPH. The radiator failed. The vehicle was taken to the dealer, who stated that the radiator, water pump, radiator thermostat, and transmission were damaged due to leaking radiator fluid. The dealer also stated that radiator needed to be repaired. The contact stated that this was the second occurrence of the same failure. The vehicle was taken to the dealer who diagnosed both failures. The manufacture was notified and offered no assistance. The failure mileage was 71,000 and the current mileage was 122,000.
My pathfinder recently started grinding into 4th gear around 40 MPH and is now lurching forward (as if having a difficult time engaging in 1st gear) after bein stopped. After researching the problem, my issue exactly fits the description of scores of online complaints from pathfinder owners of 2005-07 models who have come to find out that it is a manufacturers' defect of a coolant leaking into the transmission. When I called the nissan north america customer service to inquire about these complaints and register my own, I was told that I would have to have a diagnostics test I order to register the complaint further. I was transferred to a local dealer who confirmed the research: if my transmission fluid was milky reddish in color (which it is), then radiator fluid had leaked into to transmission and it was likely ( from this service rep's experience) that it would need to be replaced at a cost of $3500-$8000. When I inquired about the prevalence of this problem at his dealership, he was well aware of the problem and issue but because of the percentage of cars affected that is known is small in comparison to the number sold in those years, a recall was unlikely. He also indicated that the mileage on my vehicle (107000) made it even more unlikely that nissan would cover the repairs.
I drove 2hrs away to pick up my niece from college. The vehicle was fine on the freeway, but as soon as we exited, it started to sputter. We were very close to campus so we pulled in and made it through a couple more stop signs before we pulled into a stall and parked. It would not start after that. I had to tow it back home and to the dealer ship where I was told that a problem in the radiator caused fluids to mix which shot my engine. Now nissan wants to charge me $7650 for a radiator and transmission. That's ridicules considering nissan knew these vehicle had faulty radiators in them. This could have been very dangerous if this occurred on the freeway!
