    2010 Prius, found a lot of water in the spare tire well/compartment after a very wet California winter. Apparently, this is a known issue as there are 2 drain plugs to drain the water but it's less than ideal to keep having to drain it after a rainstorm. I didn't see water in the 12V battery or on the sides though, it's just in the spare tire well.

    Based on my search here and online, it seems like these 2 places (circled in red in the pic) are the main culprits for Gen 3 Prius, has anyone had this issue before for a 2010 and fixed it? Thanks.

    I just removed some plugs so the water could just pass through when it does get in I keep that track pretty clean back there I don't let dirt bull crap and all that get in there and so far I've had it dry trunk I had the battery well almost full and then I took care of that by putting some strategic holes for water to drain and I don't really see where it's getting in but I keep watching
