Folks, agree that something in the GMC/Chevy design isn't working well. I have a 2019 Silverado 1500 with a soft tonneau cover top as well. Only thing touching the tailgate is the light rubber flap that rests on top why the tailgate is closed. I can hear the actuator work. After my 4th visit to the dealer, they replace the actuator. But at times it still cycles, moves about 1/8th of an inch, but doesn't unlock. I'm "blessed" with whenever I take it into the dealer, it works for them and a short period at home. Once I tried for 30 minutes to unlock the tailgate with no luck. There is no manual override, so your essentially without any ability to have access to the truck bed. I've tried lubricate on both the underside of the tonneau flap, as well as the hinge pivot points, and locking mechanize. Nothing seems to be a long term fix. I'm really open for suggestions.
