Why does the sunroof open automatically?

[LeMatteo]

If the car sunroof closes and then automatically opens slightly, it may be because foreign objects were previously stuck in the sunroof track, causing the sunroof to memorize this position to prevent forced closure from damaging the sunroof system. Below is relevant information: Recommendations: After prolonged vehicle inactivity leading to low power supply voltage, recharge the battery and reinitialize the sunroof settings. Regularly clean and maintain the sunroof track. Cause Analysis: Factors such as prolonged vehicle inactivity can result in low battery voltage. Battery disconnection or low voltage can affect the sunroof's initialization settings, causing the sunroof control unit to fail to recognize the sunroof's exact position, potentially leading to misjudgment and incorrect sunroof operation.
