2017 Touring-L Plus, 124,500 miles.
We bought the car about 10 days ago, everything was fine until a couple of days ago when we turned on the electronic brake assist for the first time.
Since then the battery keeps draining and we have to jump start the car.
Went though all the settings and made sure everything is turned off.
But after we shut the engine off and everything has apparently turned off, the dashboard lights come back on and the gear selector LED comes back on seemingly at random or when something, such as another car, drives past. This keeps happening and appears to be the reason the battery keeps draining.

[UPDATE]
Had the battery checked at the dealership and they said it tested fine with no issues, but they couldn't fit us in for any kind of full diagnostic review and fix until 11/29/21. This was on the afternoon of the 24th.
On the 25th it died on the highway and our jump starter couldn't get it going again. A friendly Samaritan stopped and got the car started as he had a bigger jump starter in his truck. So on the 26th when stores were open again we went to Advance Auto Parts to get a bigger jump starter, had them test the battery and alternator. They said the battery was completely shot. They swapped out the battery for a newer, more powerful one, retested the starter and alternator with the new battery which all came back perfect.
No problems since then thankfully.

Thank you all for taking the time to help, especially during a holiday.
It is greatly appreciated.

Try disconnecting the negative side of the battery for 1 minute then reconnect, most times it resets stuck glitches
