Park Park comes on while driving

[GregGreg123]

Hey folks, I have a 2020 Silverado 2500 High Country Duramax. Last Oct a service warning came on advising me to service the park brake. Truck had a little over 35000 so I knew we had a warranty issue. Took to the dealer, they said it needs a new module, parts on order, safe to drive. Well, a few days later the Park brake lock on while I was backing up to hook up a trailer.  I had to disconnect the battery to release the brake. Took to the dealer, sat there for a month waiting on parts. Fast forward to now, while driving I strated to smell that familiar brake burning smell. Damned if the park brake didnt come on again. To supply as much detail as possible, the park brake light only comes on when I park it on a grade or activate it myself. Anyone run into this before? Thanks for listening.

dont know if it applies to the 2500, but the 1500's had this problem and there was an update to correct it
