What Causes All Warning Lights to Illuminate and Brakes to Become Unresponsive?

[LeOlivia]

All warning lights illuminating and brakes becoming unresponsive can be caused by the following reasons: Battery Power Status: This may be due to a drained battery from leaving headlights on for extended periods or an expired battery lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing aftermarket xenon headlights, high-power audio systems, or DVD players can also lead to vehicle electrical circuit malfunctions. Checking for a dead battery is simple—just press the horn to test. Fuel Level Check: If the fuel gauge shows levels below the red line, the car naturally won't start. Also, pay attention to fuel quality. Using poor-quality fuel will inevitably damage the vehicle. Always refuel at reputable gas stations, and when traveling, consider using a gauze filter over the fuel nozzle to trap impurities. Lack of Antifreeze: Some owners use water or substandard antifreeze, which in extremely cold winter conditions can freeze the entire cooling system, crack the engine block, and render the water pump inoperable. This prevents the car from starting and damages other engine components. Incorrect Gear Position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start. If left in R (Reverse) or D (Drive), the engine won't start. Similarly, some manual transmission cars require the clutch to be depressed for ignition.
