Is a New Car with the Engine Malfunction Light On a Defective Vehicle?

[MariaFitz]

Not necessarily a defective vehicle, it depends on the reason for the malfunction light being on. If it's due to fuel quality issues, then it's not a defective vehicle, but if it's caused by the fuel supply system, ignition system, or other reasons, it might be a defective vehicle. Below is relevant information: Identifying the Cause: The reason for the malfunction light being on is easy to identify. Service stations can simply connect a portable diagnostic tool to easily read the fault code, obtaining fault information for targeted repairs. If the engine is running normally, the owner can also try gently plugging in various wiring harness connectors, as it might be caused by a loose connection somewhere, or repeatedly turning the key to the ON position to see if the light can be turned off. Precautions: After the engine malfunction light comes on in a new car, first pay attention to whether the engine is running normally, if there is any shaking, black smoke, or difficulty starting, etc. If such issues exist, try not to start the car again. If the engine is running normally and the car can be driven, please go to a service station as soon as possible to find out the cause.
