2017 liftgate issue

Let me know and I will direct you to the thread that deals with extended warranties and the competitive pricing dealers. It is about eight pages back in the General Discussion section. Also look at Ebay or Rockauto for the liftgate actuator. Ebay has GM Dealers selling parts on their site less than the local Dealer and no tax with some offering free shipping. Looking at the TSB it does not seem very hard to replace. Good luck.

Maybe cardude2000 can confirm the part number on his work order. If you look on Ebay the picture is of the lock actuator but it is the piston actuator that the TSB shows and pictures of how to replace it.

Checked my service records. Liftgate actuator. Cost my $400 all in.

Agreed. Liftgate actuator. Just replaced mine, and it works again.

Interesting updates here. As soon as the weather was warmer, I tried it open it again and heard the loud pop and now it works via the handle. I did take it in to the dealership but they said without the issue repeating there is nothing they can do.

However, now that it works I have two other small issues.
-I can't open the tailgate via the remote unless the vehicle is started?
-Hands free sensor appears to be damaged.

Does anyone know why the keyfob won't open the liftgate? It works to open the glass, but just flashes when I try to open the liftgate.

Where is the foot handsfree sensor? It looks like I can get the part for $20-25 but there may be two different types so I want to visually see what was damaged and which one I need.

Thanks!

My liftgate will not open on 2015 tahoe. This is a nightmare. Any way to open manually

Are you saying it won’t open at all, as in it seems to stay latched or is it just not opening automatically but can be opened manually?

Reviving this thread. Need help. So my liftgate is stuck closed. Doesn’t appear to be an actuator/struts, but correct me if I’m wrong. Will try to be as clear as possible in description.

Symptoms:

- liftgate intermittently (couple times a month) for couple of years wont open with remote or hand latch button on gate. I could deal with that because I’d hit the button again and it would work. The other day real probs started….

- liftgate is closed, hit the remote button to open from a distance, lights flashed, but it doesn’t open. It felt like it was half latched and would jiggle if I tug on it hard. Kind of like a car door closed too gently, except you can’t push it closed or open it. Tried every conceivable combination of interior switch position, remote, door latch, foot trigger, gentle then aggressive pulling in that half latched position, ignition cycles, until it finally just opened like nothing happened. This happened maybe 2 weeks ago.

- since then it operates normally except that sometimes it shuts but doesn’t latch at all. Just closes. I open it with the door latch button then stop it and close it by hitting the ‘close’ button twice and then I hear it latch and screw shut.

- today I’m at the furniture store (luckily not buying anything huge) and it wouldn’t open again and was in that half latched position where I could jiggle it but it wouldn’t open or fully close. I f@&#$% with it for about 30 minutes but couldn’t get it open. So fortunately I was able to finagle the small piece of furniture thru the passenger door… but I had to drive home with the liftgate half latched expecting it to pop open. It didn’t.

Also of note it registers on the dash as ‘liftgate open’ when it’s in that half latched position. And again no combination of switches/ignition cycles/manhandling will get it to fully latch or unlatch. And when it’s not doing this bs it did today it usually lifts and lowers fine.

This thing is really making me want to hulk smash it. Any ideas? Seems like a problem with the power getting to the latch? Or maybe it is actually the actuator?



Much appreciated

Actuator may be sticking and making the other issues occur. Others have had issues with the actuator and if I remember there was a service bulletin several years ago.

Thank you.

I saw the TSB but it expired with factory warranty which for me is many moons ago. I’ll maybe start with the actuator and see if that remedies it
