Let me start off by saying that EPA estimate are just estimates. These estimates are generated in a lab with near perfect conditions and normally do not represent daily daily for most parts of the US. It's not a guarantee, but more of "There's a good chance you'll get this if your driving patterns and conditions closely match ours".
I haven't heard of anyone with the CVT reporting that they have gotten less gas mileage. I've heard that some are getting way better gas mileage than the 6M. The service manager telling you that there's no light so there's nothing wrong with it is incorrect. When things break or not functioning as they should, you don't always get a light on the console. For instance, if you have a heavily clogged air filter, you won't get a check engine light. But you will see a sharp drop in gas mileage. Take you car to a different dealership, speak with the service manager, and explain what's going on. They should at least do a once over on the vehicle to check for any obvious problems. Dealers have the responsibility to investigate your claims. If you still have problems, call the Nissan warranty line and tell them that dealers aren't investigating your claims.
