Rear liftgate/tailgate/hatch sagging
My power opening tailgate lifts all the way up, then sags down a few inches.
Is this more likely the lift system or the struts?

i have a 2007 GL320 and just had to reset my lift gate height limiter not 30min ago since i replaced the control module. On a 2007 you have to make sure that "height limiter" is set to off on the instrument cluster. Then with the lift gate closed (my engine was on but not sure that mattered) set the lift gate height by pulling the lift gate button on the door. Each time i triggered it, it lifted a little more until it get where i wanted it. then i pushed the button to close all the way.
Not sure it will work for you, but it's worth a try.

It sure sounds like symptoms of weakening struts. I mean, the motor just opens it, right? The struts take some of the burden off the motor and then keep the hatch up, right?
"Usually" you start to notice this more in cold weather.

Agree - if it was low fluid, it wouldn't open all the way. The door is the heaviest when it is fully open - meaning that's where there is the most "weight" on the struts and where they would start to give out, first.
Speaking of rear hatches... does yours close with a hard/loud "slam"? I've always thought mine closes too hard, but maybe it's normal?

Ordered a set of struts.
Will report back after they are installed, so at least the next person does not need to go through this.
