I took my certified Pathfinder in for a faulty window switch and while it was there had them check the power train for a noise I was hearing every initial 1st to 2nd gear shift after start up. Dealer notified me that the transmission fluid was contaminated or incorrect fluid. I was then told I would have to cover the cost of replacing the fluid. I contacted Nissan Consumer Affairs, as not only is the vehicle covered by the Nissan certified pre-owned program, but I also bought their security plus warranty. The transmission service is not due for another 6,000 miles, and the fluid should not be contaminated or be the wrong color and have the viscosity of water, per the dealership service dept. They are not even advising a standard transmission service, they want to replace all the fluid, as what is currently in the system is unusable. Nissan cpo is denying my claim to have the transmission fixed, taking the stance that they do not warranty fluids. I am not asking them to warranty the fluid, standard maintenance is my responsibility. However there is an issues as to how/why the fluid got contaminated and is no longer usable, and needs to be flushed. Nissan does not want any part in addressing that issue, even though their cpo and security plus warranties are supposed to cover the engine and drive train. As it turns out there are several other having similar issues, apparently there is an issues in the radiator, which also has the transmissions cooler build into it, allowing coolant to seep into the transmission fluid. Knowing this Nissan is still taking the stance that they do not warranty fluids and is refusing to service the transmission. They are basically asking me to replace the fluid and hope it does not get contaminated again and hope no other issues arise from a transmission operating for who know how long with bad fluid that was the incorrect viscosity.
