8-speed automatic: launch-year shifting, and out-of-warranty failures
several thousandTwo distinct problems. The famous one — low-speed hesitation, harsh downshifts, lurching at stop-and-go speeds — was a software/adaptation issue Toyota addressed by TSB, and mechanics say the gen-5 RAV4 got the updated version of Toyota's troubled 8-speed, so refreshed cars behave. The quieter, costlier one: the federal complaint file now contains a steady stream of outright transmission failures on 2019s at 92k–110k miles, past the 5yr/60k powertrain warranty, with owners paying for full replacements out of pocket. Toyota doesn't call for a fluid service until 120k, which owners in the complaint file find bitter. On a test drive, sustained low-speed lurching that a dealer software update can't cure is a walk-away sign on a high-mileage example.

Coolant flow shut-off valve — the 'Engine Maintenance Required' light
CoveredThe gen-5 engine uses an electric water pump and a coolant flow-control valve; the valve sticks or seeps, typically around 50–70k miles. Because a stuck coolant valve isn't an emissions fault, it triggers the amber 'Engine Maintenance Required' message rather than a check-engine light — which confuses owners and shops alike. Toyota runs Customer Support Program 24TE04 covering flow shut-off valve coolant leaks on 2019–2021 RAV4 and RAV4 Hybrid. If that message is on, or the A/C is oddly weak, this valve is the first suspect — and the repair may be free under the CSP.

Hybrid fuel tank that won't fill — fixed under 20TE04/20TE05
CoveredThe 2019 RAV4 Hybrid's defining complaint: a 14.5-gallon tank that stops accepting fuel at 9–10 gallons, cutting real-world range by a third. Dealers initially shrugged ('operating as designed'), but Toyota later ran Customer Support Programs 20TE04/20TE05 — 'refueling performance' — with remedies ranging from a fuel-gauge recalibration to a new sending unit or complete tank. Mechanics describe the problem as solved history on repaired cars. On any 2019 hybrid, fill it from low during the test-drive window if you can, and check whether the CSP work was performed.
