Water in the trunk after it rains

[Missiletm]

I have a 2011 FFH, 85k miles.  After a recent rain i noticed a drip below the rear bumper.  Pulled up the trunk liner flap and noticed I had water under the spare and the jack storage compartment was full of water.  My car was parked uphill in the driveway during the rain and it has a mild slope to the street.  
 

After drying everything out I put silicone sealant on the tail light fasteners thinking they might be the cause.  Expecting more rain tonight so we’ll see if that was it.

 

Anyone else have this problem?

 

Thanks!

Had this happen on my 2007 SEL. But only the wells on either side of the trunk. Check the vents in the rear quarter panel, you can see them from the outside, from under the fender, or rear bumper cover. I pulled them out, from the inside and then taped them mostly shut. The aged plastic curled a little bit.

Any luck fixing this? I've noticed the water pooling by the jack and same on the other side. Tried hosing down the car to see if I could watch for leaks but no luck.
