What problems does the 2015 Nissan Sentra have?

the 2015 Nissan Sentra's CVT is its most obvious flaw. Nissan's CVTs have long been a source of controversy, 

and the 2015 Sentra sadly saw the worst of the problems. According to Car Complaints,

 the 2015 Sentra CVT typically fails around 61,400 miles and costs about $3,540 to repair. Many customers who purchased Nissan Sentras drove 

them without any issues up to the 60,000-mile warranty mark before having to pay for a brand-new gearbox, which left many customers quite dissatisfied with the carmaker.

Although some drivers have gotten replacement gearboxes that are still under warranty, 

many of these transmissions have turned out to be just as flawed

as the original equipment.
