In November I was driving on the highway for 30 minutes, next thing I know is that I have no power in the engine. The car would not go higher than 20 miles and the revolutions on the motor were as high as 5,000rpm. I lost control of the car because I could not accelerate and I could not stop the car because the brakes were very hard and unresponsive. I could not move the car, it felt like the car had the brake pedal push all the way with emergency brake, I tried to accelerate but it did not move. Had to tow the car to the Nissan dealer service department. After 1 week, the service guys told me the problem was the outpeed speed sensor. After 3 days of using the repaired car, the car did the same thing only this time I almost crashed with another car because I lost control of the car again and the car almost got on fire. From the engine compartment you could see smoke coming out. Had to tow the car again to the Nissan dealer service department with no result because they could not replicate problem. The car did the same to me 2 more times and this time the dealer decided to replace the cvt transmission which I have read they have a lot of problems and because of that Nissan extended the warranty to 10 year 120K miles. After the transmission was replaced I used the car for about 1 month and the car in February did the same again. No engine power, unresponsive brakes, high RPM and smoke coming out from the engine compartment. Until when will I have to deal with this problem"?? when will Nissan correct or recall these transmissions, when a life is lost? I took the car more than 4 times before they decided to replace and fix the problem. I'm going back again to Nissan, how many times will this time will be" I have lost more than 3 months with this issue and still the car is not working. Nissan does not have a safety recall and don't seem to take seriously the problem.
