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.

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.

Vehicle was hesitating when shifting gears. Daughter pulled car in driveway, there was a burning smell. Then all of this fluid leaked on to the driveway and the car would not go into gear. Pathfinder at dealership now to be repaired. Will cost me $3000 for a known defect. Doesn't seem right that the consumer has to pay for the mistakes of the manufacturer. There should be a recall with this issue - and nissan should be the one responsible for paying the entire amount.

While driving my 2007 nissan pathfinder se, I encountered a hesitation of transmission functionality while making a left hand turn across two lanes of oncoming traffic. As I proceeded to accelerate through the left turn, the transmission seemed to slip and would not get out of first gear. Subsequently, my service engine soon light came on. The next day, I took the vehicle to the local autoexpress to have the odb-ii code retrieved, I was informed that they could not read it as it was a dealer specific code. I left and went right to my local nissan dealer who informed me that a part of the radiator had broken and the car was now mixing antifreeze with transmission fluid. They informed me that both the radiator and transmission had to be replaced at a cost of $9200.00, the dealer suggested that I call nissan as I was just 2000 miles over the warranty. After countless calls to the call center in the phillipines and the regional office in ohio, I was basically told that there was nothing they could do for me, they stated that because there were no records of maintenance being done at the selling dealership, I was out of luck. We purchased this vehicle brand new and it is a fully loaded model. The plan was to drive this to the 200k miles that nissan has been pitched to commonly achieve. Instead, I have a car in the driveway that I cant drive, I still owe $4700 on it, and it will cost me $9l just to make it useful again. Nissan should be ashamed of themselves. It will not be until someone dies that any recall action will happen. Nissan has chased away a life-long loyal customer.

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.
