2024 Mitsubishi Outlander — hybrid fuel economy dropped with no warning light — second opinion before I spend money

Same commute and driver, but average MPG is down noticeably. Tires are properly inflated. What hybrid-specific data would you inspect before blaming the high-voltage battery? Mostly looking for the right next step.

I went back under the 2024 Mitsubishi Outlander and it only happens after a heat soak, not on a cold start. Doing the boring step first on purpose.

Log the conditions before you spend. Capture voltage while the 2024 Mitsubishi Outlander is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. On “hybrid fuel economy dropped with no warning,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. I'm keeping receipts and dates in one folder.
