Typical fuel system symptoms owners report

  • Owners report the fuel tank, advertised at 17.1 gallons, only accepts about 12 to 13 gallons even when the tank shows empty or the low-fuel warning is on.
  • Several drivers say the distance-to-empty display disagrees with the fuel gauge, showing far fewer miles remaining than the gauge level suggests.
  • Owners describe reduced driving range, sometimes under 500 miles between fill-ups, well short of the range Toyota advertises for the model.
  • Some owners suspect a defective fuel level sending unit or a redesigned saddle tank that prevents a full fill, and say dealers had no fix at the time.
  • One owner filed multiple Toyota service reports over several months without resolution of the gauge and fill-level discrepancy.
