2017 Chevrolet Malibu Complaints

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...

I have a 2017 Chevy Malibu that in 2022 had a shift malfunction causing it to become stuck in reverse and roll backwards. It ended up having to be towed and was repaired in May 2022. On August 25 and 26, 2026 the car is now experiencing another SHIFT TO PARK malfunction whereby the vehicle DOES NOT detect that the shifter is in the park position. It shows a "shift to park" error on the car's dashboard and will not let me turn the car off until it detects it is in park which takes multiple times of shifting and cycling the car through the gears or repeatedly jiggling the gear selector. This is a temporary workaround and NOT a safe or satisfactory solution as this can cause a serious or even fatal accident! This Malibu seems to have a continuing problem with the shift malfunctioning and GM needs to recognize this is a continual problem and resolve it by recalling this issue AGAIN before someone is hurt or killed. I am requesting GM repair this at their expense or replace my vehicle...

While driving my 2017 Chevrolet Malibu LT equipped with the 1.5L turbocharged engine, the brake vacuum pump failed due to the pump’s mechanical drive/tang shearing. The failure resulted in loss of vacuum assistance to the power brakes, creating a significantly harder brake pedal and a serious safety concern because braking assistance can be reduced and stopping may require substantially more effort. After removing the failed pump, I found that part of the pump’s drive mechanism had sheared off and had to be retrieved from the camshaft area. I am retaining the failed pump and broken component. I am requesting that this failure be investigated as a potential safety defect because a failure of a component responsible for brake-assist vacuum can affect the vehicle’s ability to stop safely.

Transmission has been slipping since the day I bought the car in 2023 approximately at 90,000 miles, I have been keeping up with the manufactured recommendations on the transmission and march of 2026 I went to move the passenger seat and it no longer moves

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.
