2019 Chevrolet Malibu Brakes Problems

Your brake booster vacuum pump failed while you were driving, making your brakes much harder to press. When the pump broke, a piece of it damaged your camshaft and timing chain. Fixing this will require replacing the brake booster vacuum pump and inspecting or replacing the damaged engine components.

The vacuum pump has a tendency of breaking and when it does it affects the exhaust camshaft making the car completely inoperable. When this happened my vehicle lost all brakes and power and would not start. This happened suddenly with no warning and left me stranded in the middle of lanes of travel. This is a well known issue with the Chevy 1.5 L and is documented in the TSB Bulletin #21-NA-268. The vehicle was inspected following the TSB number provided and diagnosing via the information provided.

Vehicle was being driven at 60 mph on the highway when the brakes weren't responding as I was entering a sharp curve. Had to stand on the brakes and manually lower the gears to keep from hitting a tree head-on. Check engine light was on. P0014, P0017, and P0556 codes were pulled before having it towed to the first mechanic. Car wouldn't start after it was parked after the initial incident. The first mechanic was unable to diagnose so the vehicle was towed to the Chevrolet Dealership. They say the brake vacuum pump malfunctioned and caused permanent damage to the engine rendering the car inoperable and I will have to have a new engine installed. The car drove fine prior to the vacuum pump failure.

On September 28th I was driving along the highway, went to take an exit, and the brake pedal was locked. I experienced a loss of braking, hard brake pedal and increased stopping distance. In order to get the car to stop, i had to put the car in neutral and coast into a ditch/grass. Before the brake failure there was no instrument cluster malfunction lights illuminated or any warning of imminent failure of the vehicles braking system. A mechanic has informed me that the vehicles brake vacuum pump is to blame and that it needs to be repaired immediately. This part suddenly failing with no warning caused a complete brake failure within the car and posed a risk of injury or death to me and others.

Before my car gave out I was having braking issues and my car wouldn’t accelerate when I pressed the gas. Then later that night I was driving home with my mother and fiancée when my car illuminated “engine power reduced” and my check engine light came on. When I tried pulling over I noticed that my brakes were very hard. So I had to roll from the speed of 45 mph until my car eventually stopped. I was not able to stop at the stop sign so I just had to blow my horn to alert other drivers. Whenever I took it to the dealership they told me my brake vacuum pump exploded and blew shards into my camshaft. The repair was 1700 for the replacement of the brake vacuum pump and the camshaft. I talked to the mechanic afterwards and he said that this problem has a good chance of happening again because the part itself is defective and there are no other aftermarket parts to replace it. Then I go to pick up my car three weeks later, and was told that my engine should be replaced because a cylinder had no compression. The price of that was around 5000.

I WAS STATIONARY AT A RED LIGHT ON HIGHWAY 49 WITH MY FOOT ON THE BREAKS, AND WHEN THE LIGHT TURNED GREEN I LET MY FOOT UP OFF THE BREAKS AND THE CAR JUST SHUT OFF. I TRIED TO TURN THE CAR BACK ON, BUT STILL NOTHING. I WAITED A FEW SECONDS AND THE CAR STARTED BACK UP, SO I PUT IT IN DRIVE AND STARTED DRIVING, BUT WHEN I TRIED TO SLOW DOWN THE BREAKS WERE VERY TIGHT. FOR AN HOUR AND A HALF, I SAT THERE AND TRIED TO FIGURE OUT WHAT WAS WRONG WITH THE CAR. I FOUND NOTHING, SO I GOT BACK INTO THE CAR AND CRANKED IT AND THE CHECK ENGINE LIGHT CAME ON. I GOT THE CAR TO STAR CHEVROLET AND THEY DIAGNOSED THE PROBLEM AS THE BRAKE VACUUM PUMP. *TR
