Check engine light came on and truck wouldn't shift into overdrive. Pull code p0717 indicating the transmission sensor or computer was out. Took to shop and they said the transmission cooling line in the radiator cracked, the transmission fluid was then mixed with antifreeze, and it fouled the transmission parts and knock out the computer. Transmission had to be replace and the shop noted that Nissan wouldn't warranty the transmission without replacing the radiator, which they knew had to be done anyway. They said they've seen sooo many of these it's ridiculous. $4,225. 43 repair that could have been avoided if we'd just known to replace the $200 radiator.
Found out that my radiator had a failure and a transmission hose cracked inside the radiator and the transmission fluid all mixed up to invaded both the motor cooling system and the transmission. . Dont want to go in gear when turning and it make this rumbling nose when you driving it.
Transmission of my Nissan Pathfinder 2007 failed. The radiator spilled the cooling liquid into the transmission, which then proceeded to cause irrepairable damage to the transmission. Transmission replaced with a rebuilt transmission.
The transmission began to slip and the radiator fluid overflow cannister started to expel a purple liquid. Car was found to have a cracked transmission cooling tube in the base of the radiator and the antifreeze had mixed with the transmission fluid. Found out on line that this is a very common problem that Nissan refuses to acknowledge as a defect. Radiator replaced and cooling system flushed along with the required transmission flushing and fluid replacement. Repairs became very expensive. Only hope transmission doesn't fali next.
While driving the truck normally, in the morning, I came to a stop at a stoplight. Once the light turned green I pressed the pedal to accelerate and the truck was slow to respond (as if it was in a higher gear to start) once it was up to about 20mph it drove decent enough. I came to another stop and it happened again, same as before, and the check engine light came on. I was stopping at a school to drop kids off and turned into a spot and turned off the truck. It would not turn back on when attempted. I checked the diagnostic codes and came up with u1000, u1001, p0717. I had to tow it away from the parking lot a couple days later. Once I was able to check the truck out, I found a substantial amount of transmission fluid (frothed) in the coolant. I read that this is due to the internal radiator transmission cooler failing and mixing the coolant with the transmission fluid. I also found that the reason for the truck not starting was that the 10a fuse for the a/t ecu blew. I have replaced the radiator, flushed the cooling system, and am about to take a sample of the transmission fluid to see if there is coolant in the transmission before I talk to a repair facility about repairing the transmission.
I request that the dot NHTSA investigate manufacturer defects in 2007 Nissan Pathfinders cooling system and transmission as unexpected failure relates to driver safety. My 2007 Pathfinder with 90,000 miles caused a major collision with a deer as the transmission began to fail. Driving home, at around 40mph, up a hill (engine under load @ 2,200-2,500 rpm) the whole car began suddenly to "shudder"- similar to the feeling/ sound of riding over highway rumble strips. This resulted in a loss of control over the speed of the vehicle and a noticeable distraction leaving me unprepared as a large buck ran out from the tree line attempting to cross the road- the buck did not make it across. As I have found in my research afterwards, there is a widely known manufacturer defect in which engine coolant mixes with transmission fluid. The resulting "goop" shreds the internal parts of the transmission rendering it (along with the radiator and components) completely useless. These vehicles are unsafe for the roadways as this problem occurs suddenly and unexpectedly without warning. I consider myself lucky for being alive- now, but since Nissan nor any other organization is willing to recall or replace this vehicle/ affected parts, I am stuck, forced to drive on the road being a hazard to others and myself.
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 .
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.
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.
The contact owns a 2007 Nissan Pathfinder. The contact stated that the filter radiator caused the cooling to leak, which destroyed the transmission. The dealer was notified who stated that he was not familiar with the type of failure and offered no assistance. The manufacture was not notified. The failure and current mileage was 75,875.
Haven't finished paying off my car and already the transmission of my Nissan Pathfinder 2007 is failing. The radiator spilled the cooling liquid into the transmission, which then proceeded to cause serious problems to the transmission. The guaranty expired after 100 000 miles, even though prior to that the mileage the guaranty still applied. Now, in order to fix the transmission, or replace it for a new one, will cost me over $5000usd. I'd like to unite to the existing complaints/lawsuit against Nissan on the matter of the faults found in the 2007 Nissan Pathfinder, as I feel that is unfair that the company with the knowledge of fault in its product has not warned the public and has proceeded to sell the product to the public, leaving us with a faulty machine that in the end is more expensive, and not a satisfactory product. I am hopeful that the company will response to all of our complaints, stepping forward and taking responsibility for the inconvenience they have caused, and hopefully taking ownership of the expenses that due to their lack of responsibility, have been incurred on to us, the consumers.
Started noticing in March 2007 a noise like running over a rumble strip for brief periods that we thought were either our new tires or road surfaces. Later we noticed it started getting longer and it seemed liked it had a hard time shifting gears. We took it to our Nissan dealer who informed us that there was a leakage between the cooling system and the transmission which in time will cause the transmission to fail. We also found out they were aware of this problem,but we were never notified. Now they told us even with and extended warranty to 80k we were past that at 81k. I feel they should be forced back to up their known defects and issue a recall.
Car would not engage in reverse. The problem was diagnosed as my transmission failing due to design flaw that allowed radiator cooling fluid to leak into the transmission. I had to replace the transmission at a cost or $3,400. The car warranty had run out and I was not reimbursed by Nissan. Nissan has not recognized that they have a design flaw issue that is costing their car owners thousands of dollars in repairs as well as ruining their reputation.
