Common Causes
When your Hyundai’s check engine light blinks, it signals a serious issue. Understanding the common causes can help you address the problem promptly. Below, we explore some frequent reasons for a blinking check engine light in your Hyundai.
Engine Misfires
A blinking check engine light often indicates engine misfires. This happens when one or more cylinders fail to ignite properly. Misfires can result from various issues, including:

- Increased fuel consumption
Replacing worn or damaged spark plugs can restore engine performance and prevent further issues.
