Hyundai Accent check engine light issue after oil change and inspection, light temporarily off then returned on Hyundai Accent

Some Hyundai Accent owners report experiencing recurring check engine light issues after an oil change, where the light temporarily turns off before returning. These issues can stem from several factors, including incomplete oil changes that may not include a proper oil filter replacement, which can trigger the light. Additionally, low oil levels are a common cause, as insufficient oil can prompt the check engine light to illuminate. Owners may also encounter problems related to oil pressure, which should be checked to ensure it is within the recommended range. Furthermore, some owners find that a loose oil cap or improperly seated dipstick can lead to the light coming on. Air leaks in the intake system, potentially caused by dislodged or damaged hoses during the oil change, may also contribute to the issue. If the check engine light persists despite addressing these concerns, it could indicate a more complex problem requiring diagnostic evaluation. It is important to note that while a steady check engine light may not be immediately dangerous, a flashing light signals a serious issue that demands prompt attention.
