Nissan is pulling a quick one on everybody by saying the problem you're having is your transmission. Think about it people, with the car shutting off you have to remember transmission will not affect your car starting the problem is the alternator. CVT transmissions are extremely sensitive to the electrical current it gets and the alternators are faulty causing the car to rumble and shudder now Nissan would rather tell you it's the transmission because it only has a 36,000 mile warranty and the alternator has 100,000 or whatever it has don't know the exact mileage but much more than the transmission tell them to replace your alternator and it will fix the problem I had the same problem with mine. Put in new alternator and its driven like a dream ever since. Because mine started acting up right after the 36,000 mile transmission warranty and they said I had to replace the transmission luckily I bought my car through Carmax who has an excellent warranty and they took the car I told him what I thought about the alternator they looked into and presto so I drop my car at Carmax the mechanic there drove it to a Nissan dealership told him to put a new alternator in doing great ever since don't let Nissan tell you it's not the alternator they just simply want to say it's the transmission because chances are most of you are outside the 36,000 mile warranty and what they'll do is put a new transmission in and it will run better for a little bit but that alternator will chew the transmission apart again this is my third post about this I posted every few days to keep her on the top of the review list hoping to help people good luck guys. And I have a friend who works for Nissan so I was able to confirm this that it is the alternator and some of the technicians purposely keep their mouth closed because they want to get paid for doing the work on the transmission a lot of the dealerships don't pay by the hour they paid by the job so the technicians are the ones [non-permissible content removed] us along with Nissan.
I have owned my 2013 Altima 2.5 SV for just 1 month and already I have had to take the car back to the dealer 3 times for the same issue.
The issue being engine Lugging noise and vibration on light throttle acceleration from a stop at around 1500 RPM. The lugging is caused by the extremely low RPMs of engine. I have filed a complaint with Nissan Customer Care (1 800 647 7261 and was aqssigned a Regional Specialist to handle my case. According to the specialist, Nissan is trying a serpentine belt and tensioner swap. Last week, the belt swap did not alleviate my problem.
The issue could be corrected with a CVT reprogram offered to those owners that are sensitive to the noise and vibration.
After my retirement, I drove for a local Nissan dealership, as a dealer trade driver.
I was very impressed with the 2012 Altima, so I purchased a new 2013 Altima.
This was a big mistake!
Mistakely, I assumed that the engine and transmission would perform the same or even better than the 2012.
How wrong I was!
I love the car and everything it offers, but this rumbling noise from about 20mph onward is driving me nuts.
I must trun up the radio to drown out the noise.
I drove the 2012 Altimas for thousand of miles while doing my job, with complete satisfaction in the vehicle.
Please don't make the mistake as I, and purchase this vehicle.
I hope someone comes out with a class action suit
I bought a new 2013 with all the packages and really like this car. They really engineered the 2013 to meet and beat the Camry, which was the other car I looked at buying. I would recommend this to anyone looking for a great driving and has 38 MPG so fill ups are a lot less than my F150. The only thing I found was a little pain is the steering it is very tight and you have get used to it I guess.
My wife and I have owned and driven a 2009 Rogue, 2009 Altima, and a 2012 Rogue with no issues or problems with CVT or road noise until I traded my 2009 for the 2013 Altima.
When accelerating slowly from a dead stop, a deep rumbling, vibration noise starts at about 20 mph, briefly stops as you reach 40 mph, then starts again.
After 40, the rumbling continues and then the road/tire noise kicks in, which is much louder with this model. I have had the vehicle checked by my Nissan dealer several times, but the problem has not been resolved.
