What causes the Santana sunroof to open by itself?

[Nigel]

The reasons why the Santana sunroof opens by itself include low battery voltage. Power interruption or low voltage of the battery can affect the initialization settings of the sunroof, causing the sunroof control unit to fail to recognize the specific position of the sunroof, which may lead to misjudgment and incorrect operation of the sunroof. The sunroof system itself has an automatic anti-pinch function. When the sunroof encounters excessive resistance during movement (such as pinching a hand or other obstacles), it will automatically move in the opposite direction to prevent personal injury. Therefore, the following situations may cause the sunroof to move in the opposite direction during closing: 1. The sunroof system has not been regularly cleaned and maintained, with dirty sunroof tracks increasing movement resistance, or hot summer weather softening the sunroof seals and increasing resistance. 2. Incorrect initialization settings of the sunroof (such as low battery voltage or failure to perform initialization settings) or excessively dirty sunroof tracks can lead to malfunction of the sunroof. 3. It is recommended that after the vehicle has been parked for a long time, leading to low power supply voltage, the battery should be charged and the sunroof reinitialized. Regular cleaning and maintenance of the sunroof tracks should be performed.
