Sunroof drains clogged allowing water into the interior. The water drains onto the electrical connectors just in front of the doors causing electrical issues. Something stays on after the key is removed sometimes you hear it sometimes you don't. Thus the battery goes dead. Other signs are: alarm goes off for no reason, interior floor lights stay on, interior blower stays on, head lights stay on, all kinds of warning lights of different kinds show up while driving. Anybody else having similar issues.
