I have a 2021 3500 Denali diesel. My truck recently had the recall update for the radio/Bluetooth issues. When I received the truck back the inner tailgate started opening every time I opened any of the doors. Happened two weeks straight and now is intermittent. Currently at dealer trying to find a fix. Other issues were DEF tank replacement and a lot of electrical/infotainment glitches or items not working. Required shutting truck off for 5 minutes and restarting to get radio and Bluetooth to work again.

I've recently started having the same issue. Mine started with the infotainment system update. The next day the inner tailgate started opening anytime I open a door. I've been talking with dealer and no fix yet on my end. Truck is a 21 Denali 3500.
