Mazda 6 rattling noise from dashboard while idling in drive with no check engine light on Mazda 6

Some Mazda 6 owners report experiencing a rattling noise from the dashboard while idling in drive, even when the check engine light is not illuminated. This issue may stem from loose parts within the dashboard that vibrate against each other during vehicle motion. Additionally, owners are advised to inspect for loose items inside the car, such as the battery, air filter housing, and engine cover, which could contribute to the noise. Securing loose dashboard components and other interior fixtures may help eliminate the rattling. Some owners have found that using high-quality rubber supports for the engine or adding padding around loose parts can reduce vibrations and rattling sounds. Regular maintenance is crucial to prevent these common causes of rattling noises, especially when the vehicle is idle. If the rattling persists, seeking a professional inspection is recommended to accurately diagnose and address any underlying issues.
