This light is typically triggered by a fault code stored in the vehicle's computer system.

The common misconceptions:

Many drivers mistake the "Service Engine Soon" light for an indication of an oil change.

Some common issues include a faulty oxygen sensor, a loose gas cap, a malfunctioning catalytic converter, or even a failed sensor in the engine.

Adhering to the manufacturer's guidelines and seeking prompt attention for any warning lights can extend the lifespan of the vehicle and save on repair costs in the long run.

In conclusion:
