The brake pedal required excessive force, brake assist was reduced, and the stopping distance increased, creating a serious safety hazard. The check engine light had been illuminated for approximately two years before the brake failure occurred. In January 2024, I reported brake-related concerns to a Chevrolet dealership while the vehicle was under warranty, but the root cause was not diagnosed. In November 2025, after the brake pedal became hard, an independent repair facility inspected the vehicle and determined the brake problem was caused by a failing engine vacuum pump. They advised that the vehicle be repaired by a Chevrolet dealership. By January 2026, the brake condition had worsened to the point that the vehicle was no longer safe to drive and had to be towed. A Chevrolet dealership later confirmed that the engine vacuum pump had seized and damaged the camshaft, requiring replacement of both components. The vehicle remains inoperable. The failed vacuum pump caused loss of brake assist, resulting in a hard brake pedal, reduced braking ability, and an increased risk of a crash. I believe this represents a serious safety defect because failure of the vacuum pump significantly impairs the driver\u2019s ability to stop the vehicle safely. I understand GM has issued service information regarding vacuum pump failures on this engine, and I am submitting this complaint because I believe other drivers may experience the same dangerous brake failure.","products":[{"type":"Vehicle","productYear":"2020","productMake":"CHEVROLET","productModel":"MALIBU","manufacturer":"General Motors, LLC"}]}]}
