Any know of any common relay between these three issues?

I have a 2012 Kk. 28,000 miles on it. Last week on two occasions the ABS, Traction Control and 4WD Servo lights came on. Would not go into 4 wheel drive, but the problem cured itself within an hour.

Another time, a day later the vehicle locked it doors. Got another key, started it, let it idle while I went to the back to load saws, and the thing locked the doors again.

Then over the weekend with it parked and trailer with electric brakes plugged into the factor tow connector, found the jeep battery and the trailer battery completely drained in the morning. Both charged up and its fine now, but….?

When the jeep battery was being charged there was a buzzing sound from somewhere under the battery. That went away after 20 minutes of charging.

Any ideas on what I should look for?

It might all be related if there is an internal short in your TIPM (totally integrated power module), aka the fuse box directly behind the battery. If the TIPM starts to go, the door locks and windshield wipers start doing crazy things, base on what I have read.

But, it may yet be a coincidence. A wheel speed sensor or loose wire could cause the first problem, and a short in the brake controller could cause the last. The door lock thing is weird though.
