The Vacuum pump continues to go out causes code P1101. I have replaced it 4 times and people just in my town are fighting this code for dear life like me! It causes our brakes to barely work and make it completely unsafe to drive as the check engine light goes in and out for MAF sensor. It’s not safe. It needs to be recalled. It doesn’t matter if i buy the most cheapest part or expensive part. It has happened on multiple occasions where i replace it and within 2 months, its back on and does reduced power in the middle of me driving on busy roads. i’ve been almost hit and almost caused multiple accidents because I have to pull over.

I am filing a complaint regarding a brake vacuum pump failure in my 2018 Chevrolet Malibu. The failure of the vacuum pump led to a complete loss of brake assist, making the brake pedal significantly harder to press. This issue directly resulted in a complete loss of braking ability, which posed a serious safety risk while driving. The vacuum pump in these models is camshaft driven, and its failure caused damage to the camshaft. This issue is documented under GM Technical Service Bulletin PIP5835 and is known to affect certain 2016-2022 Chevrolet Malibu models equipped with the 1.5L LFV engine. The brake failure due to this issue could have led to a life-threatening accident, and I am deeply concerned that other drivers may experience this same risk. Despite reaching out to GM and the dealership, goodwill assistance was denied for this known defect. I believe this is a major safety hazard that needs to be addressed immediately. Vehicle Mileage ~120,000 Repair Estimate: $2106 for camshaft, vacuum pump, and related components Incident: The brakes became unsafe leading to a dangerous life threatening driving situation

My car brakes kept locking up and it was hard to get my car to finally stop today. There was no brake sensor or warning light. Should there be a warning light or sensor on my desk board to tell me something is wrong with my brakes ?

Brake vacuum booster exploded into the engine.

Brake pedal became hard to press down and could not stop car without having to jam down on the pedal. Per dealership the vacuum pump malfunctioned causing metal to enter engine

Defective vacuum pump damaged camshaft, reduced engine power, and caused loss of brakes while driving.

Driving normal. Upon application of brakes, brake pedal became stiff and brakes did not function normal. Had to apply immense pressure to stop and it sounded like brakes kept locking up. Vacuum pump that supplies vacuum for engine with turbo to function, along with the brake booster to be able to apply normal braking power, was destroyed. The inside of the vacuum pump is in pieces and part of the bushing that connects into the engine was broken. Caused by faulty vacuum pump, or faulty cam shaft. If this had happened while in traffic, it is likely a crash would have happened. Damage caused to the vacuum pump resulted in metal pieces in the engine block as well.

The contact owns a 2018 Chevrolet Malibu. The contact stated while operating the vehicle, the message "Engine Power Reduced" was displayed and the vehicle would not properly accelerate above 30 MPH. Additionally, while depressing the brake pedal, the vehicle failed to immediately stop, and the pedal was firm when depressed. The vehicle was later towed to the local dealer. The cause of the failure was unknown. The manufacturer was not yet notified of the failure. The failure mileage was 50,000.

I was driving down the highway and took the exit and went to hit the brake pedal and it was hard to push down. Took it into a shop for diagnosis/repair. Mechanic found that vacuum pump for brakes came apart. There is currently metal in the engine that I cannot afford to fix after already paying $500 for the new vacuum pump.
