2017 Chevrolet Malibu engine 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.

I was driving back home and stopped at a red light. When the light turned green I started driving, but my car was jerking a little too much. I pulled over and turned my car off. When I cut my car back on my brake became very hard to the point I had to push down extra hard to stop my car. I started back driving home once I realized my car needs to be turned completely off and sit. While I'm driving I see a message on my dashboard saying "Engine power reduced." Luckily I made it home safely with no wrecks, but when I had to brake my car was still moving jerking while in place. Also when I made it home and turned my car off I heard a fan like noise that eventually stopped.

The Reduce Power to Engine keeps happening. It shuts my car down and lights up the traction control light, check engine light and its a serious hazard because I travel highway to and from work and its very dangerous when you loose power to your vehicle at high rates of speed. Also my emissions is bad due to a supposed fixed recall for the catalytic converter.

While driving at highway speeds, my vehicle suddenly experienced a loss of engine power and reduced acceleration. The traction control light and engine light illuminated, and a “Reduced Engine Power” message appeared. The vehicle would not respond to the accelerator, creating a serious safety hazard. This occurred shortly after authorized dealer service involving the PCV system and related components. The vehicle did not have this issue prior to dealer service. I returned the vehicle to the dealer, and they stated they could not replicate the issue. The sudden loss of power could have resulted in a serious accident. I believe this may be related to improper dealer service, disturbed electrical connectors, or throttle body/engine management components. I am reporting this as a safety concern. I also would like to mention this safety issue has occurred now multiple times with my car on multiple separate occasions with the last prior occurrence being 12/20/2025.
