* The fuel gauge is inaccurate: Fuel gauges aren't always perfectly precise. The "empty" light might come on before the tank is truly empty, leaving a small reserve. You might still be able to add a small amount of fuel after the light illuminates.
* You're trying to fill it too quickly: Filling too fast can cause the pump to shut off prematurely due to pressure buildup. Try filling it slower.
* There's a problem with the fuel system: In rare cases, a malfunction in the fuel system (like a faulty vent) could prevent the tank from filling completely. This would require professional attention.
If you're having trouble filling your Malibu's tank, try slowing down the filling process. If the problem persists, it's best to have a mechanic inspect your vehicle.
