My car started to rattle and lose power at 45 MPH. I drove it home and tried to reverse it in with no luck. I immediately knew I had a transmission issue. I parked the car for two days and took it to the dealer who later informed me that my radiator coolant fluid had mixed with my transmission fluid and destroyed my entire car. They quoted me between 7000-9000 to fix the car. I contacted nissan who informed me that there is nothing they can do because they extended the warranty twice to up to 100,000 miles. I find this ironic since after extensive research the issue usually occurs after 100,000 miles. Nissan has know about this problem for 7 years and has chosen to ignore the issue and not issue a recall. Now the consumers have to foot the bill.
2007 Nissan Pathfinder engine complaints
Page 6 of 9: complaints 131 to 160 of 242, newest first, as owners wrote them.
Radiator cooler leaking water into transmission,and transmission oil into cooling system. Transmission stuck in 3 gear, engine overheating due to sludge inside radiator, a total disaster for a low income individual trying to make ends meet .
Driving car in rush hour traffic and car completing stopped. It took about 10 minutes to start. Once the car started it cranked for about 10 seconds before it actually started. At dealership, the car was diagnosed with needing two new cam sensors. After paying $621.00 for this, mechanic test drove car and found it to be "bucking" and diagnosed that the radiator fluid had leaked into the transmission and we needed a whole new transmission. Nissan is requiring $2,500 deductible even after they realize they made a faulty radiator/transmission.
At 99000 miles truck failed to take off then all of sudden took off then going down the highway the truck wouldn't accelerate. During a road trip which caused a 3 day delay and 3000 dollars in repair. Now fast forward to 111,975 miles and was going up hill at light and truck started rolling backwards and sputtering, took it to nissan dealership stated that coolant in transmission repair cost 7246 and still owe 9200 on truck.
We started to have a very loud and creeping noise when we put the car in reverse. Sounds like we were pulling something very heavy and the car could not resist it. Then, we also started to notice issues such as a delay in gear changes and more noises now when driving forward or in reverse. We took the car to the dealership today and they diagnosed it with a "broken trans cooler line in radiator which made the coolant leak and mixed with transmission fluid. They want us to replace the entire transmission, radiator, and flush engine block bringing the price close to 7k. I started to research this and I'm definitely adding my complaint and will surely call nissan to see what options they will give us. 2/20/15
Transmission fluid is milky colored. Loss of coolant. Transmission slipping. Somehow coolant in transmission fluid.
I was driving on the expressway and my car suddenly would not accelerate. I made my way to a street location and pulled my car on the side of the road. I shut the car off. It would not start. I had it towed to a mechanic and he said that it is the transmission.
For the past week when ever I drove my car the entire vehicle shudders, shakes and has a harsh upshift when it is changing gears. It happens the most on highways going at high speeds (55-65 miles). I took my car into a nissan dealership on 1-29-14 to get it checked out. The dealership diagnosed my car with a "broken trans cooler line in radiator which made the coolant leak and mixed with transmission fluid. Advise replace entire transmission, radiator, and flush engine block as well as replace thermostat, (price to fix: $5938.00 + 9% tax)". I researched this issue online and found this to be a common defect issue that nissan has been dancing around since 2007, as well as a class action lawsuit being filed against nissan. I bought the car on july 28, 2011, so I have only owned the car for a little over 2 years in which the dealership I purchased the car from did not inform us of this warranty being offered by nissan from the lawsuit or informed us of the possible transmission problem. I had the car completely checked out by a mechanic in november of 2013 and it passed with no issues. Now here we are 2 months later, and over 100,000 miles and my nissan experiences this issue. This can be a very detrimental and dramatic failure, causing massive safety issues if I continue to drive my car, especially on highways going high speeds. I contacted nissan this morning to see if they are going to stand behind their product and since I am only 11,000 miles over their "warranty" (which has high deductibles), they denied to help and I am left holding a $6500.00 price tag to fix my car.
The truck began shifting gears very roughly and slowly with a strong jerking motion to the truck. When taken for diagnosis was told that the transmission fluid and coolant were mixing due to a faulty radiator and thus got into transmission causing the need for replacement of radiator, flushing of fluid lines and transmission replacement approx. Cost $6000. After researching this problem, I see multitudes of other nissan customers have had the same problem. This issue is extremely unsafe on roads. My car falls outside the extended warranty given due to this problem. In addition, if my pathfinder did fall under the warranty, nissan only assists with payment to replace radiator not the damage done transmission because of the faulty radiator. This absolutely needs to be investigated further!
My vehicle just completely shut down without any warning signs or previous issues. I have taken very good care of this vehicle and the radiator has a manufacturer defect that allowed transmission fluid to leak into the radiator causing catastrophic damage to my radiator and transmission that nissan will not take any responsibility for and will cost me upwards of $5,200.00 at least.
Vehicle began to vibrate at speeds of approx 45 MPH. Over a short period of time, the condition worsened - the vibrations became more aggressive and began to occur at higher speeds. After investigation by nissan, they advised that there was an issue with the radiator and possibly transmission that was no longer under warranty because I was outside of the 100,000 mile limit. The coolant is leaking into the transmission fluid cooler line and ultimately right into the transmission, thereby causing damage that may or may not be repaired with a new radiator and transmission. Apparently, this is a know issue with these vehicles and nissan neglected to alert consumers. At this time, the vehicle is inoperable.
Nissan refuses to fully cover the repair/replacement of a faulty radiator and transmission. Nissan is currently under investigation for this neglect and is stalling on recalling the vehicles. Nissan extended a warranty leaving the burden of $3,000 deductible for the consumer. This is an appalling and sad excuse of customer service - the vehicles did not meet quality control and it is disgusting to have the customer put out that much money for a problem that existed before the vehicle left the dealership.
The trucks transmission slipped while I was merging onto the highway. The truck didn't want to move. It was very scary. I had the whole family with me.
Was hearing noise from the engine, dealer diagnosed as timing chain guides bad, said this was a "known" problem with this model. 3 weeks after fixing was going to work and the transmission went out, was advised by dealer that coolant had leaked into the fluid from a faulty radiator design on this model...estimated 6000+ for repairs. These are known issues with this model nissan and the company has offered zero help with correcting this.
Vehicle has not been warming up for about 2 weeks, never thought it was anything serious, thought it would be a heating coil or something, took it to the dealer on 1/3/14 to get an oil change and for them to look at the problem and the technician came back and said "oh you need a transmission and radiator bring the car back on tuesday" like it was something common. Just looked into the complaints did not know this was a common issue with the vehicles, needless to say this will be my last nissan. I purchased a extended warranty which they did ask me, however I did not know about the class action suit that would have covered the issue until today 1/8/14.
I was on expressway, driving approximately 60-65 miles per hour and without warning car lost all its ability to accelerate or maintain speed. Car engine would rev when you pressed on the accelerator but the car would not respond. Vehicles behind me had to hit on there brakes and go around me as I attempted to steer vehicle to the side of the expressway. Once vehicle came to a stop, my transmission would not engage in any gear leaving me stranded. I had to have vehicle towed to my home. I was informed by nissan that engine coolant had leaked into my transmission and ruined my transmission. I have since found out this is a common problem on nissan pathfinders and the cost to repair vehicle is between 4 and 5 thousand dollars.
The entire transmission melted without warning. The car could not move on reverse and only going 20mph.
The vehicle vibrated and shuttered and ceased to move. I was in traffic and luckily had a place to pull over. I had the vehicle towed to the local nissan dealership. After a discussion and diagnosis by the technician and shop foreman it was determined that the transmission and the radiator had crossed contamination of fluids resulting in the transmission becoming inoperable and requiring the transmission and radiator be replaced. The shop foreman stated that nissan knew about this defect in the radiator and the resulting problems. I am waiting to find out if nissan will help with repair cost. I was told by the shop foreman that the cost to replace the transmission and radiator would be approximately $8,000.00. .
Cracked radiator allowed coolant to leak into transmission so not knowing nissan was having this problem we had a new radiator installed and the cooling system and transmission flushed out mileage at this time was 79290 now 4 months later the transmission is shot and need a new one mileage now 83158 since the mileage is above 80000 nissan will not fix the car under there extended warranty and wants me to dole out 2500.00$. If I would have known nissan was having problems with there transmissions I would have taken my car to a nissan authorized service center the first time.
Radiator failed (product defect, no accident or external causes) and leaked into the transmission, effectively destroying it. Had to get both radiator and transmission replaced. Symptoms started with shuddering during shifting, which LED to rough shifting, gear slippage, check-engine light, and eventually the car not even starting.
I was driving my pathfinder down the highway and when I reached 40 MPH, it began to hesitate as if the overdrive was not working. As I gave it more gas, it stopped. It has gradually gotten worse to the point that anywhere from 40 to 50 MPH, the vehicle is hesitating unless you either slow to below 40 or speed up to above 50. I took it to the nissan dealer and he stated that the transmission fluid was mixing with the coolant, which means that I must pay to have my transmission replaced or purchase a new vehicle! I have since heard that there have been many reports of this same issue. My vehicle has gone out of warranty, but, if this is an issue that has been known for quite some time (years) as I have researched, then I believe nissan should have to cover the cost of replacement. Why was there not a recall on the issue, which could have been fixed easily instead of having to replace the whole thing at the owners expense! I also realize that at any moment my vehicle could stop in the middle of the road, which could cause injury or even death to me or my family.
Radiator failed, leaking antifreeze into transmission. This mixing of antifreeze and transmission fluid caused transmission to fail my pathfinder is now in a parking spot. I owe payments on a vehicle I can no longer drive, nor afford to repair.
This is all after the vehicle was serviced (by nissan dealer) for the known radiator leaking coolant into the transmission fluid. Repair back in may 2013 with approx. Mileage 68000. Now vehicle has about 75000. Driving home from dinner with wife in moderate traffic. Herd a clunk and car would not accelerate. Barely made it home. I let vehicle cool down and removed the radiator cap and found thick cream like fluid which is a definite sign of oil based fluid contaminated with water / glycol. Seems to me that nissan did not replace or fix the leaking radiator. Driving a vehicle that behaves in this manner can not be safe to drive. Back to the shop (dealer) tomorrow.
While driving the vehicle had a sudden loss of power and the service engine light came on. A local nissan dealer has informed me that due an apparent known issue for this vehicle a total failure of the transmission has occurred. The needed repairs estimate is $7,800 for a new transmission, radiator and electronic components.
Calsonic radiator issue - transmission fluid and coolant mixed causing issues with transmission. Bad transmission cooler area per aamco. Nissan is unwilling to help as my vehicle has 126k miles on it. These issues appear to be happening in a much greater % than nissan is acknowledging. They moved the warranty from 3 yrs/36000 miles to 8 years/80000 miles but it still doesn't help those whose radiator leaked after the 100k level prematurely. This is a safety issue and also a manufacturing defect issue. It seems that nissan corporate, dealers, transmission shops and other governmental organizations knew about this issue - sadly, most consumers don't. I would have gladly replaced my radiator for $500 but now I will be out $4000 because nissan didn't tell their owners about this problem.
Tl* the contact owns a 2007 nissan pathfinder. The contact stated that while at a stop light, the vehicle stalled without warning. The vehicle was taken to the dealer for diagnosis where it was stated that the timing chain system and valve body needed to be replaced. The vehicle was repaired and the manufacturer was notified. The VIN was not available. The approximate failure mileage was 102,000.
Note: affected parts are transmission and radiator (not sure what category those fall in) I purchased a 2007 nissan pathfinder from a nissan dealership less than 3 months ago. Immediately after purchasing I noticed what seemed to be a minor lack of power or cutting out when coasting downhill. I mentioned it to my sales rep, and again when I had to take the vehicle back to the shop on two separate occasions for a tire pressure gauge and rear door handle problem. I had never owned a 4wd before and it was dismissed as no big deal since it still drove okay. Then last week, over labor day weekend, my car overheated and immediately discharged a grey milky substance from the radiator without warning. It had not overheated prior to this. I had my car towed to the dealership. They informed me that both the transmission and the radiator need replacing to the tune of $6,600. The cause being the radiator fluid leaking into the transmission. This repair is over half the value of the car. I never would have purchased the vehicle had I known about the defect. At a minimum I would have insisted it be covered by warranty. I paid full retail price for the car not knowing of this defect. While I'm grateful no one was injured by this defect this time, I have no means to pay the repair costs and owe $13,000 to the bank for a vehicle I cannot drive or resell.
Major vibration during shifting gears (transmission). Concerned that coolant has leaked from radiator into transmission as has been reported on thousands of other pathfinders. Nissan should be forced to recall and replace radiators/transmissions.
Tl* the contact owns a 2007 nissan pathfinder. The contact stated that while driving 20 MPH, the vehicle stalled. The vehicle was towed to a dealer for diagnosis and the contact was informed that the vehicle would need a new valve body. The manufacturer was notified of the failure. The vehicle had not been repaired. The failure and current mileage was 102,000.
My vehicle began to drive sluggish as if it was going to cut off. When I got to my destination and tried to crank my truck to leave it would not say a word. I had my vehicle towed to the nissan dealer in morrow for a diagnostics testing. I received a call the next day stating that the radiator and transmission had failed and it needed to be replaced in order to get the truck up and running. I explained to the dealer that I had m vehicle serviced less than a month ago and there was never an indication that my transmission was failing. They quoted me 6,100 to repair my truck. I had my vehicle towed and sent to aamco transmissions, where they diagnosed my truck as needing a enginecontrol module. My issue with nissan is that there has been several complaints similiar to mine and they offered no help to resolve my problems. I would really like to speak to some one directly about my issues as there are too many to list here.
