"The cheap monitor is more than likely lying to you."
Yeah, as long as the car works (it does, starts right up, no bells or warning lights) I don't see a big rush to start chasing gremlins. I think it does have a minor parasitic drain, but that can be a real pain to diagnose on something like this. I suspect the BCM since the draw goes up a lot when the door is opened, then falls off after 30 seconds or so.

On the HHR, very little.
In the USAF I was a lifer weapons control system tech (Radar, Weapons release computer, lead computing optical sight and missile firing circuits) on the old F4-D Phantoms, then I built automated controls for production machines up til recently.
I know my way around an electron, if that's what you mean. But I am getting rusty fast.

(Like when you first reconnect the battery cable).
I pulled the XMsirius fuse, the interior lighting fuse, then put a jumper wire from the battery to the lead, then connect the meter from the battery to the lead, let the system quiet down, remove the jumper and could then see its actual draw. I think it was a tad high, but no data is available I could find.
If it becomes a problem I will put some more time into it.
