Rear tail hatch motor burned out apparently. Lift mechanism can be heard working, attempting to open the rear hatch but the gate will not unlock to allow opening except for unlocking manually from the inside. I'm looking for the part number for the new motor online now..
Lift gate didn't close properly, then got stuck and after manually opening from inside it will not not latch. Will begin to reopen. Had to turn off automatic interior lights to avoid battery drain. Have it tethered closed until get in to repair--sounds like it is going to cost about $450. Also caused interior doors to get out of whack in terms of locking. Ugh!!!
Upon activation the motor runs but the gate latch does not release.
It just doesn't close and won't engage to lock.
Tailgate want open or close all the way don't know what to do
Gate will only open partially on my 2010 ml 350. So far it still closes automatically. Don't know what to do to fix it.
Rear Tailgate does not latch
Rear tail gate not opening, battery drained.
The trunk latch stopped workin and the trunk wouldn't shut. Got it towed to the nearest dealer and they kept the car for a few days until they get the approval from the warranty company. By the time they fixed the latch, the battery was drained completely and now the dealer is billing me nearly $500 for the new battery.
car battery keeps dying and can't open trunk after I get a jump.
Drains battery all the time!!! Quoted $800 to fix. Not sure why I need to pay this. Mercedes should be covering this issue.
battery light came on during the day and later that day the hatch would close but not latch. after the battery was changed still had same problem after 30 miles. Awaiting the shop to tell me the new diagnosis.
Hatch wouldn't open or close but was stuck in semi- open state as hatch appeared to be stuck. Brought it in and was told they manually released it by crawling into cargo area. Now a noise is back like it is struggling to latch.
Found the battery drained after parking the vehicle in garage for 2 weeks. A problematic rear tailgate latch is causing this! Now, the rear tailgate can be closed manually, but cannot be latched.
Latch replaced by dealer and now a second problem at 91000 miles had same problem with a 2007 model.
Severe battery drain. Not sure what is the cause.
