Hello, I'm Brandon - Nissan tech.There is a problem with the CVT transmission.Fortunately there is extended warranty from Nissan. Follow Nissan TSB # ***** for TCM update and CVT transmission replacement. Nissan has extended the CVT transmission warranty to 10 years/120,000 miles.They will help you replace the transmission under warranty.Please rate me positive, thank you!
