I just went through this!

My battery would drain in a matter of a day or two. Same basic issue. The culprit turned out to be the ignition switch just as you suspect.

My mechanic put a battery meter on the car. My car was drawing something like 1800 mAh. The car is supposed to have a draw of around 30!

He was fiddling with the fuses (remove one at a time until the problem is identified).

Check out your frunk & rear trunk light. Does it go out when you close the trunk?

My problem turned out to be the very dim amber light in the cabin. It is supposed to go out after a few minutes, but it never went out. A new ignition switch (around $200 installed) did the trick.

Good luck.
