Typical fuel system symptoms owners report

  • Owners report the fuel gauge reading incorrectly, sometimes showing about two-thirds full when the tank is actually full.
  • Some drivers describe sudden unintended acceleration while parking or shifting into drive, requiring hard braking to stop the vehicle.
  • Several report the engine stalling, shuddering, or quitting when coming to a stop, with dealers pointing to a possible detached baffle inside the gas tank causing fuel to slosh away from the pickup area.
  • Others describe the fuel gauge suddenly dropping from nearly full to zero while driving, followed by the engine failing to restart even after adding more fuel.
  • One owner reported the vehicle accelerating and going out of control, ending in a crash, though the cause was not confirmed.
