Check the anti-theft switch
Some models are equipped with rear rear door anti-theft switch. If the lock switch is mistakenly touched, the rear door cannot be opened normally outside the car. Check and make sure the anti-theft switch is not operated by mistake.
Check connecting rod and spring
The spring of the rear tailgate connecting rod may fail due to jamming or deformation. Check the condition of links and springs and repair or replace them if necessary.

A motor failure of the rear and rear lock block may cause the rear door to fail to open. If the motor is faulty, replace the lock assembly.
Use the emergency switch or pull the cable
Most models have an emergency switch or cable inside the trunk or under the seat. The taildoor can be opened manually by flipping the switch or pulling the cable.
Check the buttons and sensors
The rear taildoor button may fail due to short circuit or moisture, and the sensor fault may also cause the taildoor to fail to open. Check and replace the corresponding button or sensor.
