Since 5.8 update (may have nothing to do with that), powered rear liftgate will not allow height reset and gives 3 beeps when button on lid is held down. Opens and closes fine. I tried a software reboot, but no help. Wondering if anyone else ran into this "3 beeps" scenerio, either before or after firmware update? And...is there a fix other than taking in to service? Thanks for your time.
Don't hold it down, the three beeps means something's wrong. Open the hatch all the way, then manually position it where you want it. Then, press and hold the button on the hatch until it long beeps. That will set the memory for it.
