2016~2020 Battery drain in 2020 Mazdas

Vertigo88, yes the 3 year/36k mile bumper to bumper warranty covers this repair. Customer service excellent so far, i dropped the car off on friday afternoon, they put me into a new CX-9, received a call this morning for update, shd be done in a few days (waiting for part to come in).
This is great news. Thanks for the update. Please keep us posted if there are any other issues.

I parked my car Saturday night and haven't driven it since. I'll try to start it up tomorrow or Wednesday to see if the battery drained again. If so, it will be going in to the shop (I probably should have taken it in for a full diagnosis already, really).
