2025 Honda Civic — hybrid fuel economy dropped with no warning light — buyer question from Phoenix

Write down what you already tried. A second data point from another 2025 Honda Civic owner helps more than a generic diagnosis. I'd do that before spending real money.

Don't overfit one forum story to your car. If it still isn't clear on the 2025 Honda Civic, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. Post the numbers (or the code) and people can get more specific. I'm keeping receipts and dates in one folder.
