2017 Chevrolet MalibuRecalls, problems, MPG & safety

“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…”

“When the vehicle is shifted into Park and the ignition button is pressed, the vehicle fails to shut down. The dashboard displays a "Shift to Park" warning message, indicating the vehicle does not recognize that the gear selector is physically in the Park position.To shut the engine off, the driver must repeatedly wiggle, slam, or cycle the gear shifter back and forth into Park until the electrical sensor finally registers the connection. This creates a severe safety hazard, as the vehicle can roll away if left unsecured, drains the car battery, and prevents the doors from locking properly.Crucially, this defect traps drivers inside an operational vehicle for extended periods while they repeatedly struggle to force it to shut down. This poses an immediate risk of heat-related illness or death (hyperthermia), especially in high-temperature environments, during heatwaves, or for vulnerable occupants like children and the elderly who cannot exit the vehicle safely until it is off.”

“Turbo cooler and turbocharger failure, diagnosis and replacement on February 4 and February 17, 2026 by a certified GM dealership. Replacement of these parts was not included in service bulletin N222372590 (issued 12/22/22), which covered 100% replacement for the exact parts for the exact engine for a number of other GM vehicles manufactured from 2016-2022. The total repair cost for these two part replacements was $4,951.11 for a car that was purchase just two months prior for $17,000. A great disappointment! Code for issue in both cases was P0299. The failed parts resulted in significant engine power loss, which made it unsafe to drive as acceleration away from intersections and on entering the highway was poor!”
