NHTSA Complaint #11581164 — 2021 CHEVROLET SILVERADO 1500

My 2021 Silverado (~29500 miles) pickup has a multifunction tailgate. I noticed about two weeks ago that the tailgate would unlatch and come down at random. I might unlock and open the door or I might start the vehicle or I might turn off the vehicle and the tailgate would come down. It is very random and has no pattern to why it is happening. The gate is electrically controlled inside the vehicle as well as the controls on the gate itself. I find this such a serious safety concern because you can not tell when it might come down and if you are pulling a trailer it could be disastrous. My main concern is that I might be backing into a parking spot, which I frequently do, and the tailgate is either down or comes down at the wrong time and at best I might back into something or at worst back into or pinch a person between the tailgate and another object. I have seen this problem reported online but I can not verify independently nor first person that it has happened to others. I am having the vehicle serviced next week under the existing warranty. There never were nor are there now any warning lamps to indicate a problem. Until the repair is completed I have put two bungee cords in place to hold the tailgate up.
