I purchased my 2015 Nissan Altima brand new from the dealer. In Sept 2015 at 25,000 miles, while driving in the middle of the freeway, the car slow down as if I was driving in a low gear. The RPM went up, but the car is moving very slow. I stop the car and called the service department. They told me to stop and park the car then restarted the car after giving it serval mins of cooling down. I took the car the service the next day, they couldn't find anything wrong with the car. I continue to drive the car for another six or so months then the same happened again. I took the car back to the service department, no problem was found again. Couple months later, the car stop in the middle of the road. I took the car in, still no problem ws found. They said they can't mimic the problem and asked that I contiue to drive and stop and park if the problem arise. I told the supervisor/manager at the service department that I don't feel safe driving my family around in a car that stop in the middle of the road but can't find anything wrong. I don't know much about the car, but it has to do with transimition because of the check engine light. I felt that the service department is prolonging the real problem because the car is still under the warranity, and I felt that the problem will be discover once it's out of the warrnity coverage. I have two major concerns: 1. I am worry for the safety of my family when I am driving them around the car that can stop anytime in the middle of the road and cause the accident. 2.I am worry, I'll be making a payment for a car that I can't drive once it is no longer be cover under the warranity and it will costs thousand of dollars to get it fix.

The cvt transmission in the 2015 frontier is probably going to fail after 50,000 miles. Most of the time it works, but on occasion it stutters on acceleration from a standstill, or vibrates excessively in general. When, not if, the transmission fails it could cause serious injury or death because the car did not accelerate when it was expected to.

Cvt transmission vibrates excessively in interior (floorboards, steering wheel, gas pedal, and and me) noise level extremely high inside car. Dealer and Nissan America say they will not fix or buy back car. Purchased new in Sept 2014. Had same car 2014 model that had no vibration or noise. Dealer had seven test drives and all agree with me, but no one would commit to saying the car needs to be fixed - they say it could be defective or could be a design problem. Either way I am stuck!!! would not recommend this car to anyone.

I was driving my 2015 Nissan Altima on the road and there was heavy traffic so it was sort of stop and go and lots of idling. Each time I pressed on the gas, it seems the car hesitated to go. After I got to my destination, I then drove onto interstate 85 in gastonia, North Carolina and the car started making a loud whistling noise and would not accelerate. The drive shaft also started shaking really bad. The car stalled as I was driving on the interstate and I was able to pull off and the car coasted off the highway. The car stopped on me. I attempted to contact the dealership that I purchased the car to get direction on what to do and they wouldn't speak to me or return my calls. I ended up calling Nissan roadside assistance in re the car. The guy asked for my VIN # and I gave it to him and he immediately asked if my car's engine stalled on me. I advised that it did in the midst of my driving with my children on an interstate. He advised they would send a tow truck to get my car but there wasn't anything he could do for me to have transportation and I'd have to speak with the nearest dealership to see if they could provide a loaner. The dealership ended up diagnosing this as a bad transmission in this brand new car. I wanted to know how the roadside assistance guy knew that this car had stalled on me prior to me explaining the problem. The dealership that repaired it also asked me if I had had this problem 3 times prior. I had not. When I purchased the car it had 101 miles on it and I believe this car had problems that they were aware of and they sold it to me anyway. I requested a replacement vehicle from Nissan Consumer Affairs B/C I have no confidence in this car as it was a new car with a bad transmission and I do not trust it's safety for myself and my children. I believe that this is not a one time thing and this has happened previously.
