2017 Chevrolet Malibu: start-stop system problems

Filed Aug 29, 2026 · Electrical, Engine · FL

The vehicle is experiencing an apparent fuel-system malfunction. The vehicle has a very strong raw gasoline odor, significant difficulty starting, and appears to be consuming fuel at an abnormally high rate. After filling the fuel tank completely, I drove approximately 20 miles at most and the fuel gauge decreased by approximately one-quarter of a tank. The engine oil also has a strong gasoline odor, indicating that fuel may be entering the engine oil. The exact failed component has not yet been diagnosed. The vehicle is available for inspection upon request. The strong raw gasoline odor and apparent rapid loss of fuel create a concern for a fuel leak and potential fire hazard. The vehicle also has difficulty starting and shuts the engine off when the automatic stop/start system activates while stopped at a traffic light. This creates a safety concern because the vehicle may not restart normally when traffic begins moving. I am concerned that the vehicle may have a fuel-system defect similar to the high-pressure fuel pump/fuel-line issue previously recalled on certain 2016-2018 Chevrolet Malibus. No. The problem has not yet been diagnosed or confirmed by a dealer or independent service center. The symptoms have been personally observed while operating the vehicle. This was my first step as this happened at 10:30pm. No. The vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or another official representative. I am reporting the problem because of the severity of the symptoms and the potential safety risk. There were no warning lamps or messages that I noticed before the problem occurred. The first symptoms were a very strong gasoline odor, unusually rapid fuel loss, and significant difficulty starting the vehicle. The vehicle also shuts off completely when the automatic stop/start system activates while stopped at a traffic light. These symptoms began recently.

On or about may 17 and on may 22 2018, the engine stalled when I attempted to enter an intersection after stopping at a stop sign. The green "engine on" light remained illuminated. I had to push the engine start/stop button to turn the engine off, then push it again to restart the engine. After the may 22 incident, the car media system malfunctioned after the car was restarted. The screen displays were normal, but there was no sound from any source including the turn signals and 4 way flashers.
