What good is the alert if it doesn’t tell me what is actually broken? In my case, there was nothing wrong with the rear access. It was closed and secure, it was not in fact open. The window was closed and the tailgate was solid and securely closed and locked. The alert should have said something like “Rear Access Sensor Broken - make sure your tailgate is closed and secure.” Then, nix the forced dome light “ON” for goodness sake! It can’t be fixed on the spot so meanwhile we drain our batteries and drive illuminated by the interior lights until the sensor - not the rear access - is fixed? This is not an urgency. People are capable of checking to see if their access is closed or not!! You can’t even disconnect the battery without a wrench on hand. Give me a break Chevy/GMC!

@louis1 there are some sensor in the latch assembly that could register your access as being open. It's a pretty involved task so try to reset your computer first. Disconnect the battery cable and for a few minutes keep holding the battery cables together. I prefer to leave them disconnected overnight and reattach those later. this should force your computer to relearn. If that does not work your have to take a look at the latch assembly. Last it could be that the BCM (Body Control Module) is failing, or has corrosion or loose wire on one of the connectors. Check on those as well

I read through all this and opened and closed all the doors looking at the DIC to see that they were properly sensed. Did the same with the rear hatch but did not look at the DIC when hatch was opened. I started planning to take the Suburban to the dealer to troubleshoot the problem and my wife noticed air noise coming from somewhere. I pulled over into a parking lot, looked at the rear hatch which was firmly closed, cycled the hatch anyway... still no change. Then, happened to note that the rear window was open about an inch. Pushed the window closed and alas! The problem went away. I would have found the problem a lot faster if the DIC had indicated "Rear Window Open" rather than "Rear Access Open".

This saved my neck! It was the window, this literally just happened! Thanks for posting!

So, I just had this issue come up on my 2018 Suburban LS, (no power lift gate) Would not go away, when I closed it again both glass and gate, still had "Rear Access Open" warning on dash. Couldn't lock it either as alarm would start going off. Next day wouldn't start, had it jumped and then went to shop to get battery tested, it was at 100 cranking CCA, can't figure out how it was starting in the first place, they were shocked as well, showed me the test print out. Anyways changed the battery, and after a couple of cycles the warning message has gone away. Hopefully it doesn't come back.
