My 2019 1500 has 41,000 miles. Something is draining the battery when everything is supposed to be off. The check engine light is on, and I was told that the code was specific to a transmission shift module. Could this module drain the battery over night?

If it is still under warranty why not have the dealer check it out.

there is a recall for your truck for the uconnect. other owners of your vehicle have brought it to the dealer because the uconnect cycling on and off every 45 seconds was killing their batteries. also causing other electrical problems. it is something to look into.
