2017 Chevrolet Malibu brakes problems

Filed Oct 23, 2026 · Brakes · CA

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.

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.

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.

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.

I had to slam on my brakes but they were very hard to press and almost non existent and steering was also difficult. Managed to get car to side of road but due to very hard to non existent brakes I did graze a truck and damaged my rear drivers side fender. I am very lucky I didn’t get injured and was able to mostly miss the cars stopped in front of me. I also have the shift to park issue happen at least 4 times a week.

I was driving my car on the highway doing 65 mph when all of a sudden my car started rapidly jerking losing the power to accelerate and entering “limp mode“ there was multiple cars behind me when my car lost the power to accelerate. I was in the far left lane and couldn’t even go higher than 7 miles an hour and had to cross across three lanes at 7 mph on a 65mph highway to pull over. I had my children in the car and almost caused a huge accident dude to this issue. The issue in hand is the vacuum pump. It completely shattered in my engine, causing severe engine damage. And it caused my brake pedal to become hard as a rock. I couldn’t break without using my emergency break. I had no brake power at all. My car had to be towed.
