Bought a new 2015 Rogue. 29,500 miles later I need tires. I had to replace one tire after 3,000 miles and it cost $277.00. Who ever heard of a car needing new tires with less then 30,000 miles. I was told they put cheap tires on their cars by a guy in the service department.
The service manager called me back after my second call. He very nicely explained I needed tires because the factory tires are "soft" and tend to wear faster. It was an answer but not a good one. I still need tires.
I am down the road buying tires. Will not go back to Nissan again. This is an unnecessary, unexpected expense.
Continental tires do not warranty their tires by mileage it seems.
Buyer beware.
