Display Randomly Turns On with Engine Off

[Pepper1979]

My 2019 Ram 1500 Longhorn started having display and dash gauges powering on then turning off randomly after engine has been off overnight in the garage. Noticed this happens early morning in the garage and the truck has been off for hours. I don’t have my key or alarm fob nearby, but am concerned my battery may discharge. I checked the fuse box and nothing appears loose. No new installations recently either. Any ideas?
Thanks

Do you have any aftermarket accessories ?

Once it goes fully to sleep, that should not happen. However, it can pickup a FOB from a long ways off. Think remote start range. Try putting the FOBS in a Faraday box and see if that fixes it. Also, if you have a door not fully shut, hood etc, it will cause this to happen.

I have a compustar alarm professionally installed 2 years ago.

I keep both my factory fobs in faraday sleeves whenever I’m not driving.

Installed an Apple air tag a year ago. Not sure if that would cause an RF type interference with the engine off.

Maybe ask your installers if they know of any other instances ?
