Why does my Kia Niro's gas mileage seem lower than advertised?

I've been driving my Kia Niro for a few weeks now and I've noticed that my gas mileage isn't as high as what was advertised. I've been driving efficiently and following all the recommended maintenance, so I'm not sure what could be causing this discrepancy. Can someone explain why this might be happening and offer some advice?

It's possible that your driving habits or the routes you take could be affecting your gas mileage. I suggest keeping track of your trips and making note of any habits that could be decreasing your fuel efficiency. You can also try driving in eco-mode or utilizing cruise control to see if that makes a difference.

It could also be an issue with the car's fuel system. I recommend taking your Kia Niro to a trusted mechanic for a thorough inspection. They will be able to identify and fix any potential issues that could be causing the lower gas mileage.

Have you checked your tire pressure recently? Low tire pressure can greatly affect gas mileage. Make sure your tires are properly inflated and see if that makes a difference in your fuel efficiency.
