What is the reason for the ignition warning light turning red and the car not starting?

Poor engine combustion is the main reason for the ignition warning light turning red and the car not starting. In automotive design, to ensure the engine is in good working condition and to maintain its normal working lifespan, an oxygen sensor is installed on the engine to monitor the combustion state. Once the engine combustion state deteriorates, it not only pollutes the environment but also leads to fuel waste and excessive engine wear. Below is additional information: 1. During car operation or at the moment of ignition, the engine warning light on the dashboard (usually red or yellow) illuminates. In most cases, it does not disappear automatically, though in rare instances, it might. This is referred to as the engine warning light coming on. 2. The indicator lights on a car generally come in the following colors: red, yellow, green, blue, and white.
Last time my ignition warning light turned red and the car wouldn't start - it was so frustrating! I had to call a tow truck to take it to the repair shop. The technician diagnosed it as an aged, dead battery with charging system failure. This light usually indicates the alternator isn't charging the battery or the battery is dying, causing startup power loss. I initially tried jump-starting with a friend's car but it didn't work at all - the battery was completely dead. I'd suggest checking for loose or corroded battery terminals. Regular maintenance can prevent such embarrassing situations. Make it a habit to monitor vehicle warning lights and check the dashboard routinely - timely maintenance saves both hassle and money. If encountering similar issues, don't force DIY solutions. Seek professional help immediately to prevent problem escalation affecting your trip.
