Is it normal for the engine warning light to come on in a new car?

Sensor issues: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine warning light to come on. Maintenance issues: Poor engine maintenance is the most common reason for the engine warning light to illuminate. Vehicles have specific maintenance cycles, and if the owner does not perform maintenance on schedule, coupled with poor driving habits, it will increase the burden on the engine's operation. Eventually, the warning light will come on as a reminder to take care of the vehicle. Fuel quality issues: The fuel quality here includes both fuel and engine oil. The fuel added to a car usually has a specific grade, and engine oil can be semi-synthetic or fully synthetic. Manufacturers generally recommend which grade of fuel and type of engine oil to use. If the owner does not follow these recommendations, it will lead to engine wear over time.
