Rear Liftgate not closing completely

I have a 2007 GL450. Every five or so closings, the power liftgate will not close completely so the car won't lock. Has anyone else had this problem?

I've not heard this PARTICULAR problem description, but the latch adjustments are known to be very sensitive to getting it exactly right.

Yes, I had the same problem got fixed yesterday. Dealer did some adjustments on the rear door the first time. I drove my car for a few days and had the same problem. Second time, dealer ended up changing the compressor for the tailgate. Its workin so far.

When you had it fixed at the dealer, was it covered under the warranty?

We had this problem with our 09' Gl550 at delivery and had it repaired a total of 3 times. It initially was a bad wire contact, then hinge/latch adjustment and lastly, the computer software had to be updated. The last fix was the one that did it. Its been 9 months now and all solved.

Liftgate is/was a common problem point on the GL. My latch was replaced last week also due to an opening problem. All covered under warranty as long as your 4 years are not up and you have not exceeded 50K.

Very fast
My wife's GL450 is now having this problem, and it's out of warranty. The motor that controls the latching doesn't seem to be running. The fuse is fine, and there is power to every on the liftgate (power close, lock, wiper, lights, etc all work) so I don't think this is a contact issue.

Anyone replace this themselves?

There are knobs either on the tail gate or the frame that allows adjustments. Just turn them and it will lock. I don't have to move them much to make the tail gate close and lock again on my truck.

The motor that engages the lock isn't turning (totally silent), so in my case, it's not an adjustment issue.

I can now tell you that it costs about $600 to replace the lock motor. It wasn't an alignment or software issue. *sigh*

Received the same ridiculous quote on my 2008 gl CDI-hatch "soft closes" but only latches about 50% of the time and it has gotten worse. Anyone know if you can just disable the motor function (remove fuse?) and slam it manually, i.e. old school?

I know this is odd, but when you close the gate are any of the doors open? There is an issue with the negative pressure. Had my mechanisim replaced on my 2011 and it works great.

I just had my liftgate fixed. My problem is the hatch wouldn't close when the weather got cold. It was a switch and motor that needed replacing. $1400, but covered on my extended warranty.

My wife's GL320 CDI had a liftgate tgat would not close. I replaced the lock mechanism in about 45 mins and it seems to work perfectly. It's not too bad of a job to do.

Lift Gate Draining Battery

Has anyone else had issues with their battery dying due to Lift Gate Issues? The other night the car began making a beeping sound at 3am, beeped for 8 hours in my garage before I could contact MBrace. No power, would not start, etc.. Tech arrived and jumped, car started, no issues in the past few days. However, this happened two years ago (no beeping, but car wouldn't start) and we replaced battery @ $300+. The Lift Gate motor doesn't seem to be engaging properly and therefore not completely locking the gate. Normally, I have to slam it shut in order for it to lock. Now, the handle on the outside seems to be sticking. Service at Dealership doesn't feel battery needs replacing, I am concerned due to the fact battery is out of warranty in Nov. 2014. As a side note, car is also out of warranty. Any suggestions?

Yes, absolutely!
If the latch handle above the license plate sticks in the squeezed position, I believe that it keeps power to the hatch hydraulic lift pump running and will kill the battery within a day. Seemed to stick more if it's dirty back there. Just make sure the handle is not in the squeezed position until the handle is replaced.
(I wrote about it here .)

And yes, mine doesn't close completely all the time. When it doesn't fully engage, I notice that the hatch button on the driver's door is lit, and I just tap the button, and the door motor completes the closure and turns the red light out.
