Is It Normal for the Warning Light to Illuminate in a New Car?

It is abnormal for the warning light to illuminate in a new car. Here are the relevant explanations: 1. When the ignition switch is turned on: The dashboard indicator lights will illuminate, which is the car's system self-check diagnosis, and they will automatically turn off after a period of time. 2. Battery fault light: The battery is depleted or faulty, indicating a power system issue. 3. Engine fault light: Poor combustion state, engine knocking, poor fuel quality, or excessive engine carbon buildup. 4. Oil warning light: Insufficient oil level, excessively high engine temperature, improper oil selection, or blockage in the oil pipeline. 5. Tire pressure warning light: Tire damage or air leakage, or a faulty tire pressure sensor.
I've driven several types of cars, and warning lights coming on in a new car are usually not normal, as this indicates the system has detected an issue. New cars undergo strict inspections before leaving the factory, so there generally aren't major problems, but warning lights might illuminate due to sensitive sensors, like oxygen sensors falsely reporting emission issues. Last time, my neighbor's new car had a light come on; they went to the dealership, scanned the code, and it turned out to be a minor software glitch—fixed for free in ten minutes. New cars come with warranties, so don't hesitate to schedule a check-up to prevent minor issues from becoming major ones. Also, pay attention to the light color: yellow for warnings, red for emergencies—address them promptly to ensure safety. When parking, check if the fuel cap is tightly closed, as improper tightening can also trigger the light. Paying attention to these small details can save you a lot of hassle.
