2022 Toyota RAV4 — hybrid fuel economy dropped with no warning light — second opinion before I spend money

MarketHauler673Community StarterAug 20, 20262022 Toyota RAV4 Hybrid XSECentral Jersey
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? If I figure it out I will update the thread. Mileage is about 42,000.

Don't overfit one forum story to your car. If it still isn't clear on the 2022 Toyota RAV4, a specialist hour can be cheaper than another round of parts. That's where I'd start. This is from a 2022 Toyota RAV4 in Central Jersey. Keep sale price, fees, and rate as three different conversations. I'm keeping receipts and dates in one folder.

Write down what you already tried. A second data point from another 2022 Toyota RAV4 owner helps more than a generic diagnosis. I'd do that before spending real money. Verbal 'we'll take care of it' is not a plan. I'd rather be boring and correct. If this is nothing, great. I want that in data.

If it doesn't change the out-the-door or the repair estimate, it's noise. I'm keeping receipts and dates in one folder.

Not convinced that's the whole story. Verify the cheap/easy branch on the 2022 Toyota RAV4 before a big repair or a big spend. I'd do that before spending real money. No need to make it theatrical. This is me being the wet blanket on purpose.

I hear you, though I'd still want a second check. On the 2022 Toyota RAV4 in Central Jersey, I'd fix the thing you'll notice every day before chasing spec-sheet extras. Then you'll know the next fork. On “hybrid fuel economy dropped with no warning,” that was the fork that mattered for me. That's the sequence I'd use. I'd rather look cautious in this thread than stuck later.

I'd keep this practical. Verify the cheap/easy branch on the 2022 Toyota RAV4 before a big repair or a big spend. Then you'll know the next fork. This is from a 2022 Toyota RAV4 in Central Jersey. Learned this the expensive way on a previous car. I've seen both outcomes, which is why I'd test instead of assume. I'll update if anything new shows up.

Write down what you already tried. A second data point from another 2022 Toyota RAV4 owner helps more than a generic diagnosis. Then you'll know the next fork. If they can't show the line item, I assume it's hiding. Not trying to scare you — just skip the expensive first guess. This is the version I'd tell a friend.

Write down what you already tried. A second data point from another 2022 Toyota RAV4 owner helps more than a generic diagnosis. That's where I'd start. Had a similar mess a couple years ago and that's what finally sorted it. I'd sleep better after that step, even if it finds nothing. Might be overthinking it, but I'd rather overthink than overspend.

Thanks — that narrowed it. I'm going to try the simpler check on the 2022 Toyota RAV4 first. Might be overthinking it, but I'd rather overthink than overspend.

Owner notes beat generic advice here. On the 2022 Toyota RAV4 in Central Jersey, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “hybrid fuel economy dropped with no warning,” that was the fork that mattered for me. This is from a 2022 Toyota RAV4 in Central Jersey. Write the result down so the next test isn't a repeat of the last one. Wrote this up on my lunch break.

Agree — and I'd add this: On the 2022 Toyota RAV4 in Central Jersey, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “hybrid fuel economy dropped with no warning,” that was the fork that mattered for me. This is from a 2022 Toyota RAV4 in Central Jersey. A shop burned me once by skipping that step. That's my plan before I call anyone.
