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?

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

 

#20-NA-040: Pickup Box Power Endgate May Not Open on Initial Press, or May Not Open at All

What about the manual release?

where?

 

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.

      Post your UOA, (used oil analysis) here

      By Black02Silverado · Posted

      Here's the second UOA on my 22 Wrangler with the Ecodiesel. This has 5k miles on AMSOIL Signature Series DEO 5w-40. The first one was dealer installed oil, no clue what it was, the second is what AMSOIL recommended, European FS 5w-40, Most of the Ecodiesel world is showing great results using the European MS 5w-40, I figured I would see how the DEO works. This is using an Ecoguard oil filter. It's my understanding this engine likes to shed aluminum.  We will see. So far I don't think this is too bad.

      Disable DRL's

      By revmanii · Posted

      I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
