Water damage in spare tire well?

That is a very very common complaint they all leak eventually. There's cracks in the roof where the roof meets the rear quarter panel in the hatch valley. Water drips down from there into the trunk. if really bad leak water will get under the rugs in the back seat and stink the car up.

The thing to be concerned about is the 12 volt battery is now sitting in water. Water fills up the hole it sits in. It will rust out that battery well and may make it unusable to hold the battery.

Take the battery out remove its drain plug and soap and water the hole out dry it out see how bad the corrosion is. Try to remove the corrosion best you can and spray paint it.

If the car lives outside looks like this car does do not remove the drain plugs but drill small weep holes in the plugs. if you leave the plugs out mice love the prius and will get into the car and will do really bad damage to the cars wiring. Really common. In fact take out the cabin ac air filter behind the glove box to check for meece activity and also open the ENGINE air filter box and check in there. Mice like to turn both those spots into a Days Inn.

PS-Bite in the butt part is water also leaks right on to the hybrid battery fan connector and rust/rots that connector out also. Its directly in the path of the water drip. Its behind the passenger side rear cover above the 12 volt battery. When that connector fails the car will throw a master caution triangle.

 

Yes, as Ed said, it's very common... Pull the black trim strips off the roof and get it real clean under there so you can inspect the welds, which is a common place for the leaks. It's pretty easy to patch up. There's other places the leaks come from, but those are the main ones.

 

That's crap Toyota puts in the car tap it with a hammer it'll fall apart scoop it up throw it away so it's not vibrating around there in the back when you're driving most of it'll come up with light hammer taps It just breaks If you feel you have to lay something down there you can take some half inch rubber foam or something trim it to where you like it sit in there there's no need but some people. Water doesn't run uphill from the ground up so that water you're seeing is coming from the hat seal down to that area or from a tail light leaking or something like that It's not coming through the floor of the spare tire well through that stuff that's breaking and cracking and sitting in the spare tire well it would just run right back out the slits that came through right? Of course it would so it's coming from higher up there's thousands of discussions on that here first thing I do is open the hatch and see if I can see my nice black rubber seal or if I have dirt and tree shit level with that seal If I do I imagine you'll put on a rubber glove and finger out all that nastiness then use some cleaner some water etc stop parking under trees whatever it takes or you can keep fingering and cleaning every so often however it makes you happy but that's where your leak is coming from somewhere near the rear hat seal downward

 

HAIL SATAN!!! Sometimes I sit one of the grandkids in the trunk and spray it with a water while they watch I've even giving them a water-based marker and let them mark on the metal the spots where they see water dripping they do it carefully believe it or not and then I take a look.
