Symptom: The pump clicks off after about 9 or 10 gallons even with the low-fuel light on. The tank is rated at about 14.5 gallons, so your real range is much shorter than expected. This affects the hybrid RAV4, not the gas-only model.

Likely causes

  1. Tank fill behavior. The long RAV4World thread collected many owner reports. Toyota responded with a customer support program that replaces the fuel tank and fuel sender gauge when a dealer confirms the problem.
  2. Gauge reading. The sender is replaced along with the tank, so the gauge should read correctly afterward.
  3. The pump nozzle. Some nozzles click off early. Filling more slowly helps a little but won't fix a tank that doesn't fill.

Cost

No charge under Toyota's program once a dealer verifies the problem. Program terms have time and mileage limits, so check your VIN with a Toyota dealer.

DIY or shop?

Dealer. There's nothing to fix yourself, but keep a record of your fill-ups.

Useful steps

  1. Keep receipts showing how many gallons went in when the low-fuel light was on.
  2. Ask a Toyota dealer to check your VIN for the RAV4 Hybrid fuel tank program.
  3. Follow the dealer's fill-test instructions (fill until the nozzle stops).

Safety / mechanic note

This isn't a direct safety defect, but running out of fuel sooner than you expect can leave you stranded. Plan fill-ups by miles driven until it's fixed.
