Why does the engine malfunction indicator light come on in a new car?

[VonEmiliano]

New car engine malfunction indicator light comes on because there is a fault in the engine. This situation in a new car is considered a factory quality issue, and it is recommended that the owner promptly visit a 4S dealership to request warranty repair. After the engine has been used for a period of time, carbon deposits will accumulate, which can lead to engine damage, difficulty starting, poor acceleration, excessive engine noise, and other phenomena. The accumulated heat can cause irregular engine ignition, leading to engine knocking. In such cases, the engine malfunction indicator light will illuminate. Carbon deposits in the engine should be cleaned regularly, typically every 40,000 to 50,000 kilometers. Some owners wait until the malfunction indicator light comes on before checking and cleaning the carbon deposits on the engine.
