2017 MS liftgate

[P@n+#er]

The rear power liftgate opens and closes randomly when I approach it. Sometimes only partially going up or down, but without the fob or remote engaged. Charge port usually opens whenever the liftgate acts up. Anybody familiar with this issue?

Does this happen with fobs, or phone paired as key?

Try switching fobs.

Never seen it, have you tried rebooting the car, press brake and both scroll wheels at the same time until the MCU reboots? You can also logoff from the mobile app at the same time, and take the battery off the fob (or put them far away). If these doesn't solve it, you may have to schedule service.

Usually happens when I approach the vehicle with the fob in pocket. But sometimes I return to the car and the liftgate is already open.
I have rebooted with no change in behavior. I’ll try the fob and mobile app suggestions.
