Why can't the Mazda3's brake be pressed down and the car won't start?

The reasons why the Mazda3's brake can't be pressed down and the car won't start are as follows: Dead battery: It may be caused by leaving the headlights on for a long time or the battery reaching the end of its lifespan. Generally, car batteries need to be replaced every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures. Low engine oil: If the oil gauge shows the level is below the red line, the car naturally won't start. Also, pay attention to the quality of the oil. Wrong gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start the car. If it's in R (Reverse) or D (Drive), the car won't start.
Having driven for so many years, I've encountered this issue with the Mazda3 (Axela) before. If the brake pedal can't be pressed down and the car won't start, it's likely a problem with the vacuum booster system. The car's brake assist relies on the engine to provide vacuum pressure. If the engine isn't running or there's a vacuum pump failure, the assist disappears, making the brake pedal hard and impossible to press. The ignition system is designed to require pressing the brake pedal first, creating a deadlock. Possible causes include a ruptured vacuum hose, vacuum pump failure, or brake fluid loss. I was in a hurry to get to work at the time, tried a few times without success, and immediately called for repairs. I recommend you first check the brake fluid reservoir and hoses for obvious issues. If nothing's apparent, seek professional help immediately—don't force it yourself. Safety first.
