Water collects inside trunk

UPDATE:
I just wanted to let everyone know that upon further inspection (by myself) I noticed the left drainage tube had been disconnected from its insert. I think this may have been caused by loading and unloading cargo from my trunk two days prior.

Thanks for your interest.

Hey everyone,

I recently purchased my Camaro in February and haven't really noticed this issue before. I've washed my car several times and haven't noticed this. However, lately after a day of rain I opened my trunk to put something inside and saw a small amount of water puddled up on my rubber cargo mat. I have not clue where this is coming from, all the rubber sealant around the trunk lid is perfect... Any help would be appreciated.

BTW, I've booked an appointment with my local service department as my Camaro is still under warranty and extended warranty. I'd just like to know if anyone has experience with this problem or if you'll have any ideas as to why this happens. Thank you in advance.
