No problem on mine, but MY 19 is an early 2018 build and a Bighorn, no fancy buttons on FOB or in Truck to release, just switch on gate itself. I have found though that you have to close the gate securely, not slam but close Firmly to get the tailgate ajar alarm to turn off. But I also have a full tonneau cover so of course have to open cover before open gate, though I doubt that means ne thing.
ADDED: I do not like not having a keyed access on tailgate, but as far as Security issue, it is a good idea. I also have a tailgate lock on the gate itself to prevent gate taking a walk, if I had to leave open somewhere. Lots of fast take things are receiving the 5 Finger Discount: Like tail gates, bumper pull trailers, gas in your gas tank and Catalytic Converters. I still have to install security wiring on the CAT yet to stop/slow down that issue.
