OWNER ANSWER
Why does my SEALION 7 boot open when I move the charging cable?
If your SEALION 7 has the hands-free boot sensor, move the smart key away before handling the cable behind the car. BYD’s handbook says the sensor can open or close the boot when it detects a foot movement under the rear bumper with a valid smart key nearby.
For the SEALION 7 with automatic kick sensing, as described in the right-hand-drive handbook 07.2024 EN_V0.
- Park with room for the tailgate to move. Check the matching handbook or equipment list to confirm that the car has the hands-free sensor.
- Before handling the cable behind the car, place the smart key somewhere secure away from the rear detection area. Keep your feet clear of the area beneath the bumper and use the normal boot button deliberately when you need it.
- During the next normal charging setup, note whether the lid stays still as you route the cable. One owner reported unwanted opening while dragging a charging cable past the rear. The report does not identify which movement triggered the sensor.
What success looks like
The lid stays still when you move the cable and responds normally when you deliberately operate a boot control.
If that did not work
If the lid still moves unexpectedly, stop using the area beneath it and ask BYD to check the kick sensor and tailgate switch inputs. Tell them whether the key was nearby, whether the lid was open or closed, and whether anyone pressed a boot control. If the lid is uneven, resists or will not latch, use the linked tailgate fault guide.
Safety note: Keep people and cables clear of a moving lid. Stop and step clear if it starts to move unexpectedly.
