Consumer Description

Brake pedal is hard when starting the vehicle. Brake pedal turns soft when engine is started. The brake pedal is so hard that it requires significant force to depress sufficiently to start the engine. This indicates loss of vacuum in brake booster when engine is off. The vehicle is equipped with a start/stop system and it seems likely that the brakes would not sufficiently hold the vehicle when the start/stop system turns off the engine.
