I have two separate incidents regarding the vacuum pump on my 2017 Chevy Malibu. About two years ago, I was driving on the freeway, my brakes locked up, Car was dying, turns out my vacuum pump had exploded internally, causing metal pieces to go into my engine, it was in my oil as well. I had to replace the vacuum pump, and because it broke, it threw off the timing on my camshaft. I had a mechanic look at it and he had to tap the camshaft back into timing. Today, October 2026, I was on my way home from work, and my brakes were locking up and grinding. I had to use a lot of pressure for the brakes to even work. The break is very hard. Again, another vacuum pump failure. I’m hoping this time it does not lead to another camshaft issue as that is an expensive repair.

I was driving on the tollway at 75 mph when I saw stopped traffic ahead of me, and when I tried to apply the brakes, they went from soft to hard and completely stopped working; I had to swerve across lanes into the grass to avoid a massive accident and to save my life, as well as the lives of my passengers and the people who would have been involved. The vacuum pump had completely blown up, causing the brakes to fail, and it also destroyed my camshaft, so I lost engine power as well. I looked it up online and it is a very common issue that GM needs to address because of how severely dangerous it is.

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!

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 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 as it seems to be a LEMON!

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.

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.

I have a 2017 Chevy Malibu 2.0 T. The incident involved the braking system. I was driving and as traffic came to a stop, I pressed the brake to stop and my brakes gave out. I immediately lifted my foot and press extremely hard on my brake pedal and was able to stop though the stopping distance was much further and nearly caused an accident. I have now taken the vehicle to a Chevy certified dealer and it has been identified as a brake vacuum pump failure. GM has had many issues with the brake vacuum pump across many of its models.
