Hybrid MPG suddenly down with no warning lights

GarageGarage53Community StarterFeb 13, 20262025 Honda Civic Sport Touring HybridSeattle
2025 Honda Civic Sport Touring Hybrid, about 118,000 miles. Same commute, same driver, but average MPG dropped pretty sharply over the last month. Tire pressure is good. What hybrid-specific things are worth checking before assuming the battery is getting weak?

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. I'd want that in writing, not as a promise. If this is nothing, great. I want that in data.
