Liftgate malfunction

Hi All,

 

Recently, i have been experiencing some issues with the powerlift trunk. 

 

  • About a few weeks ago, it slowed down on open and close.
  • When closing, it would sometimes not latch and then open slightly. It would open again when the exterior trunk open button is pressed.
  • But, it would not close by pressing the button on the inside of the trunk door. I would have to manually close it.

 

I am suspecting the powerlift struts and possibly motor. 

Any suggestions?

 

As always, its very difficult to get clear answers from the UAE dealership. Its easier with this forums understanding.

 

Thanks,

Arbee

Because your Edge is exhibiting several Power Liftgate symptoms -- change in open/close velocity; a sporadic failure to pulldown and/or latch; cargo area pushbutton opens but does not close while exterior pushbutton performs normally -- the best-first step may be to perform the Power Liftgate Initialization procedure, which involves de-powering the Rear Gate Trunk Module (RGTM)...

 

Document download link> Power Liftgate Initialization - 2016 Edge Workshop Manual.pdf

 

You will notice this RGTM de-powering can be done either by pulling the RGTM fuses or by disconnecting the Edge's battery.

 

If you choose pulling fuses, there are two -- F76 in the Battery Junction Box (BJB) and F10 in the Body Control Module (BCM)...

  • Release the tabs.
  • Lift and position the top part of the junction box aside.

Be aware that the alternative RGTM de-powering method -- Battery Disconnect procedure -- offers these cautions...

 

NOTICE: Removing the negative battery ground cable at the LH strut tower will not disable the vehicle's electrical system. Failure to disconnect the battery cable from the battery post may cause component damage.

 

NOTE: When the battery is disconnected and connected, some abnormal drive symptoms may occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven to allow the PCM to relearn the adaptive strategy values.

The following Workshop Manual section provides a wonderful explanation of Power Liftgate operation in conjunction with the RGTM and other components...

Please report back on the outcome of the Power Liftgate Initialization procedure. 

 

Good luck!

That is an excellent write-up.  I may be having some issues, but I haven't had the car long enough yet to really test it.  It did do something funky yesterday, and my wife saw it on the screen, but I did not, and it was all good when I looked.  Anyway, I'll keep watch on this to see how it went.

I have a 2019 Edge ST with a power liftgate.  The other day, I was opening it when it was next to the garage door. Thought I had enough room, but didn't. I stopped the door with my hand, and it reversed, and I stopped it again and then it didn't move anymore.  I closed the door by hand, and it latched.  After that, It won't power open or close.  The remote or button on the dash will unlatch the door, but the actuators won't work.  I checked the 30A fuse in the engine compartment which was good.  There seems to be another fuse in the passenger compartment, but there is no way I can get my hands in there to check the fuse, let alone pull it and replace it.  I tried disconnecting the battery, and that didn't work either. Is there anything else I can check before taking it into the dealer$hip?

See if this helps. One thing that can cause this is to manually close the liftgate, but not latch it.

 

To reset the power liftgate:
1. Disconnect the battery for 20 seconds then, reconnect the battery.
2. Manually close and fully latch the liftgate.
3. Power open the liftgate by using the integrated keyhead transmitter, or the instrument panel control button.
Note: If the power liftgate system is turned off in the message center, the system cannot be activated with the outside release handle or rear cargo area control button. The system will need to be turned on to resume operation with the outside release handle or rear cargo area control button. The power liftgate is still operational through the use of the remote entry transmitter and instrument panel button when the power liftgate is turned off in the message center.”

You might also need to set your opening height of the liftgate. Manually move the liftgate to the max opening height or wherever you want it.

Then press and hold the open/close button until it beeps for confirmation. Hopefully this may be all it needs. I'm thinking it might've gotten confused?

I am also having the same issue. Exactly the same. Liftgate was hitting the garage door so I stopped it with my hand. Now it doesn’t work anymore. I tried the reset on the liftgate. It beeped but still doesn’t work. Seems like this should be easy to resolve….but how?

i was wondering what would happen if the liftgate collides with something .. like a concrete block wall? i kinda wish it was still manual like my 2011 edge. did you guys ever get this resolved?? is there a way to make it manual again??

Depend on how fast you were moving. I accidentally had the liftgate up and pulled into the garage. Top hit the bottom of the garage door. I was moving really slow and it didnt hurt the liftgate at all. (Made a hell of a thunk however.) 

 

If you hit a concrete wall, if it were still opening, I'd imagine the hatch would simply reverse when the hatch realized there was an object present. May scratch the paint however.

 

To make it manual, you can just turn off the automatic function. On mine (Lincoln MKX), there's an on/off setting in the information center. When turned off, it must be  opened and closed manually.

My 2015 Ford Edge SEL liftgate works well but the issue is if while unloading you accidently get your foot under the sensor, it starts closing while you are bending into the back to get items. Even if the liftgate hits your back it will not stop closing and continues pressing down. My husband had to pull himself out as the pressure kept increasing. He scraped his back getting out and the door continued to close and then locked.  This was very scary and dangerous. I would think it would operate like a garage door opener that if something was in the way it would stop and go back up.  I called a Ford dealership to see if there were any recalls or reports of this happening and their only reply was no, but I could bring it in for a $200 diagnostic and then would get an estimate to fix it. Also, they would have to have my car for at least 5 days before they could do the diagnostic.

I have a 2019 Edge Titanium. the lift gate opened/closed a couple ties, then stopped, I have tried the battery disconnect trick, but still nothing. when we hit the button on the liftgate, the dash button, or the button on the remote, it does unlatch, but does not open/close automatically anymore. 

Any thoughts?

This has been seen many times here in the forum. Any possibility you can run the codes?

 

When you open the liftgate, it unlatches and then what happens? Does it make any kind of feeble attempt to raise or is it dead?

 

If dead, my first suspect is your vehicle battery is getting weak and needs replacing. (#1 cause #1).

 

If it tries to open and fails, try lifting the liftgate full open and see if it holds its position. If it doesn't, the pneumatic lift arms are getting weak and need replacing. (The motor lift needs the lift of the pneumatic lift arms to raise it the first 50% of the lift.) 

 

Any binding when opening manually?

 

If the Hatch stays full open (or nearly full) the pneumatic lift arms are good and the liftgate module "could" be at fault. You'll need to have the dealer replace it as it needs programming. If the module is failing, it should set a BCM code.

EDIT: my apologies for not searching for other threads about this issue.  I’ve found a couple…feel free to ignore or redirect me!
 

 

I’mhaving trouble with the liftgate on our Edge, been going on since 11/3.

 

When pressing the button on the lift gate, the driver side will begin to lift, barely crack the seal, and then reclose itself. The passenger side doesn’t even look like it is even moving.  The button on the dashboard doesn’t seem to work either. It has opened maybe a couple of times since then, but it is VERY intermittent/random. It did work once/twice using the kick sensor, then still did what I mentioned previously.

 

I’ve tried all the tips/tricks mentioned here and elsewhere: checking/pulling fuses (all good fuses), disconnecting the battery cables for a few minutes, press and hold the tailgate buttons to try and reset it.  I even tried resetting the opening height.

 

Does anyone have any idea what it could possibly be?  I’m not afraid of trying to fix it myself, if it’s possible.  I was wondering if anyone could give me an idea on what else it could be or something else to try.

 

thanks in advance
