Approx. 10k on the vehicle when the brake pedal would get hard upon braking regardless of rain, snow or shine, it eventually got worse. After taking the car into the dealership 3x's the tech realized that the brake fluid was low. The tech found that the master cylinder was leaking break fluid into the brake booster. The brake booster was more than half full with fluid by the time the problem was noticed. The master cylinder was replaced on the vehicle due to mechanical failure. The brake system is still having various issues that cannot seem to be resolved with the vehicle having only 36,555 miles. The rotors have been turned so much that they already need replacement. The Malibu's brake system is faulty and needs to be investigated. I've talked to other Malibu owners that have had similar issues.
