There is transmission issue with this vehicle when driven in excess of 2 hours. It appears to overheat and will not drive in excess of 60 MPH until it cools down. This is a known issue and I did open a case with nissan who refuses to cover the repair. Nissan case # 31337703. Nissan doubled the powertrain warranty on models 2003 - 2010 as a result of this issue but is refusing the stand behind this one which was presumably made in 2010. Problem first noticed a year ago and 2 mechanics could not duplicate the issue as it has to be driven a long time to heat up. It is only on long trips that this happens. Nissan requested we take it to a dealer for diagnosis and after 6 hours (and $150 charge) they said it had the incorrect transmission fluid. I am the original owner of the vehicle and never changed or authorized anyone to change it so that is a false statement. I was chastised for not visiting a dealer in 5 years... My response was if it is not broke why fix it? This vehicle is now used for primarily long road trips to school and it is frustrating that nissan knows there are thousands of reported issues with the CVT transmission but will not accept responsibility for this one. I have reached out to nissan and escalated my appeal as high as the executive specialist who would not consider standing behind their product. Sent a few e-mails to management (customer experience) which have gone ignored. Will be disputing the credit card charge for 'diagnosis' as that was a 6 hour wait for them to do nothing more then look at the fluid and accuse us of changing it to an unsupported fluid. Given the known design and reliability issues with this part I simply request nissan to cover the cost of replacement to which they refuse, causing a severe safety issue when this car is driven. In city driving it works without any issues.

Nissan claims that their CVT transmission issues were fixed for the model year 2011 sentra but that is a lie. The transmission overheats and then the car goes into limp mode which is extremely dangerous in the highway because it looses almost all power. Nissan extended the warranty for model years 2006-2010 to 120,000 miles because they knew there were issues with the transmissions but they refuse to acknowledge the issues that still exist with the 2011 model. I live in florida which has a warm climate and the issue normally manifests itself after about an hour of driving in the highway. After careful research, it seems that people that live in mountainous area have the same issue. To make matters worse, when the issues with the transmission started around september 2015 while going on a 500 mile trip, we took the car to nissan of pompano beach upon our return and they told us we needed a new transmission. We didn't believe them at the time because we had just driven the car about 350 miles after the problem started and the transmission was still working. The issue seem to only manifest when the weather was really warm and the car was been driven for several miles. Therefore, we instructed them to change the transmission oil and went on our way wondering if that would fix the issue. Since then, the car has gone another 15k miles with the same transmission. Since we have been taking shorter trips with the car the issue had not manifested itself again until now so we took the car to nissan in miami and again they told us that the car needs a new transmission. Given all the problems they have been having with the CVT transmission, I believe nissan should either extend the warranty on 2011 models or at least make sure that dealerships try to install a transmission fluid cooler to see if the customers issue goes away.
