In the USA, the check engine light is a ubiquitous automotive feature introduced in the 1980s as part of emissions regulations. Drivers often delay addressing it, but it can indicate anything from a loose gas cap to serious engine damage. In Brazil, the awareness of this feature is also common among car owners, though some older vehicles may lack this diagnostic system.
