Power Tailgate Won’t Open

[BruceP]

New 2020 Silverado 2500 with power tailgate. On vacation and went to open and it’s not working. Yes there is a tonneau cover but it’s been on for months and never had a problem before. Got the cover open and tailgate still not working. Doesn’t work with remote, button on the tailgate or button inside truck. When I push button inside cab it says “tailgate release unavailable.”

 

Anyone have a similar issue and hopefully a solution?

Is it in park?  Gate won't open in drive or reverse with the truck off.

What about the manual release?

Make sure it’s fully closed, I have a GMC multipro and if it’s not fully latched it won’t open, won’t even try to open. I have to push it in and make sure it’s latched fully, then it works fine.

There is bulletin out for this issue.  It replaces the endgate actuator.    Part number is 84873070

There is no manual release...not without opening the tonneau (if you've got one) and then opening the tailgate access panel that is at the top inner side of the gate.

Too many engineers and their "bright ideas" working at GM right now LOL.

To be fair, tons of vehicles have electric trunk releases that work just fine. Sure, most of them have manual backups. Having a button only seems like a solution looking for problems.

I just put a GM Soft Tri-fold on my 2021 Silverado and had this issue. I simply put Vaseline on the rear seal that contacts the tailgate. Problem solved. It doesn’t stick shut anymore.

Hi, I too am currently having a problem w my tailgate. If I hit the button on the back it will slowly open for about 6 inches and slam down.  If I hit the button inside of the truck it said tailgate unavailable. From the button I can still open but not properly and it will not close with the button.  Exactly the worry when I got it.

Same issue on ‘21 Silverado 3500 HD dually.  Going to try and access it from the access panel and see why there’s no power at all to the tailgate.  Glad I don’t need to pull my 5th wheel right now.

My wife has a 2020 Silverado 1500 and since day one we’ve had to hit the tailgate button twice to get it to open and sometimes in the winter you’ll have to hit it 15-20 times.

 

Today to took the panel off the inside the tail gate and found that there’s about 1/2” of play on each linkage so there’s almost no pull on the laches, there’s no adjustment so I just bent the rods to shorten them so there’s no play and now the gate opens first tons every time.
