Rear hatch problems
I own a 2008 ML350 and I have been experiencing a rear latch problem. The latch doesn't always thoroughly shut, which causes my battery to die. I have taken my car to the dealership on two separate occasions, with no luck.
Any suggestions?

I checked this website and couldn't find any known problems with the rear hatch.

Search the GL forum for this. You will find a lot of complaints. Even a few lemon law issues. Posts by "MomsBenz" should be your start point.
Good thing is there is a fix. It is well known to all Mercedes dealers. Talk to your dealership manager, or go to another dealer.

Its not the motors; its an adjustment problem coupled with a software bug: The hatch closing force is adjusted within the hatch close controller and when the force is too low the hatch doesnt close. The controller then attempts to close the hatch over and over, never shutting down until the battery goes completely dead. The normal shutoff alerts were not applied to the hatch controller software so it doesnt stop when the battery goes low and the end result is a *really* dead battery.
The normal procedure is to readjust the latch so that hatch doesnt have to compress the seals arond the gate as much and then reprogram the controller to apply more force then usual. The trick is tu use more force because the problem often does not manifest itself until it gets cold. When its cold the motors have less power and the seals are stiffer which causes the failure to close.
