Last year while driving my car I begin to notice a "jerking" motion. I took it back to the Nissan dealer and they said that I would need a flush and that this would take care of the problem. Fast forward roughly a month later and my car completely gave out while driving to work. No warning just stopped driving in the middle of the road. I had the car towed back to the dealer where they did a diagnostic and said that the transmission was "gone" because the coolant was leaking into the transmission. I simply can not afford to get the repairs done being a single mother. I have called Nissan and filed a complaint and was told that because my car was slightly over 100,00 miles they couldn't do anything for me. I feel as though this is s defect in the equipment that Nissan is seeking and the mileage should not matter. There should be some sort of resolution on the matter. As it stands my car has been immobile for the past couple months and I am still making payments. It's a sad situation and Nissan should be ashamed, something has to be done.
I noticed a vibration, like you were driving on the rumble strip on the side of the road between 40 and 50 mph, at around 2000 rpm and the transmission would not switch into overdrive. I took it into the dealership and the service tech diagnosed the problem, cooler system failure, in about 5 minutes after taking one look at the transmission fluid and coolant. The cooler had failed leaking coolant into the transmission fluid and vice versa. They replaced the transmission and cooler assembly. I had just under 97,000 miles on the vehicle and had to pay $3300 for the repairs. I am very disappointed in Nissan and how they have handled what is clearly a prevalent and known issue with cooler failures in certain models. A $3000 deductible (plus tax) that expires at 100,000 miles for an issue that's known to occur at close to 100,000 miles is not much of a consolation.
Our 2007 Nissan Xterra, purchased brand new, began to overheat. Upon checking the fluids I noticed the coolant level was dangerously low. I was certainly puzzled where the fluid had gone because there has never been any visible leaks or any warning lights or any other symptom to draw my attention. I began to look into the situation because I was puzzled and quickly learned of the massive number of Nissan owners experiencing the same problem. Sadly, I was now one of those victims. Yes, the coolant had contaminated the transmission fluid via the faulty transmission cooler. There is a class action lawsuit that I am sure you are aware of but I was unaware of. I do not recall any contact notifying me of a class action lawsuit and the potential damage. I had no reason for worry because my vehicle had not given me any trouble signs and the fluids have always checked normal during normal service checks. Like many, I cannot afford to shell out the dollars that this negligence on Nissan corporation behalf has caused. I encourage you to please force Nissan corporation to issue a recall requiring them to make all the appropriate repairs for these damages. Please, do not put a cap on the mileage or set the mileage relatively high if you must. My vehicle has only 89,000 miles and only gave signs of damage less than 500 miles ago.
Coolant leak into transmission. Common problem to design flaw. Costly $5,000+ repair.
