Transmission fluid is leaking into coolant.
The contact owns a 2007 Nissan Pathfinder. While parked, the vehicle failed to start. The vehicle was towed to an independent mechanic who diagnosed that there was coolant leaking into the transmission, which caused transmission fluid and coolant to mix. The mechanic stated that the transmission needed to be replaced. The vehicle was not repaired. The vehicle was towed to a dealer, but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 117,687.
The transmission on my 2007 Nissan Pathfinder started slipping so I had it looked at and found out the coolant leaked into the transmission. I have 118,000 miles on it and unfortunately it looks like I am out of luck. I an very disappointed in Nissan since they know the failure does not occur until about 90,000 miles.
Car had begun shuttering and engine would rev real fast. On particular day car actually quit working for good, husband had pulled into parking space because check engine light came on and from that point forward the car will not crank. When car first started shuttering and revving, car was taken to transmission business and there were several cars of the same make and model (not certain that all were of same year) waiting to have transmissions replaced because coolant had leaked into the transmission and gradually killed them. Worker at transmission shop knew exactly what was going on when husband explained what the car was doing, and said there were many people who had had the same complaint.
The dealer I work for had checked my vehicle since it has been leaking pink fluid from my engine turns out they found on my 20007 Nissan Pathfinder a coolant in transmission meaning there is an internal transmission cross contamination cooler failure. Bottom line they told me I needed a new transmission and fixed me hoses for the power steering fluid costing me over $5300. 00 with a huge dealership. I just bought this vehicle in February 16, 2015 from a private dealer and now I am stuck with a huge bill to fix something that should have been made a aware of nationally. This vehicle's carfax is awesome and no engine issues which I made it my business to make sure everything is okay with this vehicle. Please take care of this. . . Why do I have suffer being without a car again as a single mother of three this is not right.
The transmission cooler leaked coolant into the transmission causing the transmission to fail unexpectedly while driving down the highway at a speed of 40-45 mph.
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.
My wife was driving home from picking up our children from school. She was traveling approx 65 mph when the vehicle lost power, became unstable, and would not accelerate. She said that it was like someone put on the emergancy brake with five times more force than normal almost causing her to loose control of the vehicle. Upon taking the vehicle to a repair shop the problem was found to be that coolant had leaked into the transmission and had distroyed the transmission computer and the transmission.
