My car has developed an issue with the remote not working, no lock-unlock and If I disconnect the battery and reconnect the rear flashers stay on but still no communication with the remote and repeatedly reconnecting the battery will at some point make the flashers stay off. Sometimes doors lock by themselves when car just sits for a minute.
Thinking the body control module is acting up ....what do you think?

Also I had made some posts a while back on my interior lights turning on all the time when towing the vehicle or connecting - disconnecting the trailer hitch which was really odd. Locking/unlocking from the remote would shut the lights off. I would see/do this from my tow vehicle and see it in my rear view mirror while driving.
One time during a lightning storm the sun roof opened ,interior lights came on and hazered lights for no reason after a lightning crack. That was crazy and for sure a "static electrical issue" I even grounded the trailer with rubber straps to eliminate the issue to no avail.
