Why is the Kia Niro's mileage decreasing?

I've noticed that my Kia Niro's mileage has been decreasing lately. I've only had the car for a few months, so I'm concerned about what could be causing this. The car is well-maintained and I follow the manufacturer's recommended maintenance schedule. Can someone give me some insight on this issue?

Hi Alex, it's normal for your car's mileage to decrease slightly over time. However, if you notice a significant decrease, it could be due to a few factors. One possibility is that your tires may need to be replaced or rotated, as worn tires can negatively impact fuel efficiency. Another possibility is that your air filter may be dirty and in need of a replacement. I would recommend checking these factors and if they are not the cause, bring your car in to a mechanic for a thorough inspection.

Hey Alex, another reason for your car's decreasing mileage could be due to your driving habits. Do you frequently drive in stop-and-go traffic or use heavy acceleration? This type of driving can lower your fuel efficiency. I would suggest trying to minimize these habits and see if your mileage improves.

Hi Alex, do you normally use a roof rack or carry heavy items in your car? This can also contribute to lower mileage. The added weight creates more resistance, which requires more fuel to be used. Consider removing any unnecessary weight for better fuel efficiency.
