I know several people on this forum experience battery draw, leading to dead batteries overnight and shortened battery life. I found a video that is good on seeing the process of tracing battery draw. The car he diagnoses also has the after blow and air quality features, but it came down to a simple fuse for him. It's interesting to see him keep the door/light pins depressed for the trunk and hood (while they are open) so they don't trip circuits or prevent the modules from sleeping.

View for yourself because a thousand words written here cannot explain how well this video shows the proper way to trace and fix your battery drain issues.
