What is the reason why the electric tailgate cannot automatically rise?

[Guzman]

Electric tailgate cannot automatically rise reasons and solutions are as follows: Electric tailgate troubleshooting: Push the tailgate to its maximum height and hold it in that position. Press and hold the switch button on the trunk lid for about 4-5 seconds to try resetting the tailgate. If the tailgate still cannot rise after resetting, the car must be sent to a 4S shop for inspection and repair. Precautions for electric tailgate: When using the electric tailgate, occasionally closing it manually is not a problem. However, never force the trunk down by pressing it, as this can damage the motor and support rods.

A couple of days ago, my car's tailgate also had this issue, which turned out to be caused by insufficient battery voltage. The power tailgate requires stable electrical support. If the battery is aging or too much power is consumed by leaving electrical devices on while parked, the system will enter protection mode. Also, check if the kick sensor area near the rear bumper is covered in mud, as the sensor won't receive the unlock signal if obstructed. Finally, inspect the tailgate tracks for any foreign objects. Last winter, my car's tailgate malfunctioned due to ice blocks jamming the tracks.
