Default Water in spare tire compartment

While showing off my Prius to my brother, I proceeded to show him the rear storage compartment and the spare tire below. I was shocked to find about a gallon of water in the spare tire cavity. When I got home I pulled everything back out and pulled the two plugs at the bottom to drain the water. I am at a total loss as to how the water got in there. There is no evidence of water marks anywhere. Anybody else experience this?

No, but I'll be sure to check mine to be sure I'm not lugging an extra 8 to 10 pounds of smelly, mosquito-infested Florida swamp water around everywhere I go!

My rear storage compartment is bone dry. I know that because I unfortunately just finished putting the spare on the car.

A piece of metal sliced the tire. Dang! And of course, on a holiday weekend.

For leaks, a fantastic (and dirt cheap) sealant is roofing cement (that black tar for your house). That worked great in my Omni, where a rather long line of rust allowed rain water to dribble in the car... soaking the carpet. The trick is to cover it with newspaper immediately after squirting it, to avoid anything from touching it and getting all sticky before it dries completely.

I had the same problem with my Ford Escort Wagon, and I had the window seals tested for leaks by Speedy Auto Glass; results, negative. Stymied, I put newspaper along the sides of the trunk area and finally found the culprit: a damaged seal on the side marker light. You may have a similar problem with your Prius. If you take out the storage bin and the cargo deck that covers it, then carefully lay a sheet of newspaper across the opening, you should be able to track where the water might be coming in from.
Because the tire well is the lowest point in the car, the water might not necessarily be coming from the rear end of the car but could be trickling along the sides, possibly from a leaky door seal.
The proximity to the high voltage battery would make it imperative that you eventually locate the source and stop the leak, as I am sure you are doing.
On a really dry day, you can still use the newspaper trick; move the source of water (garden hose) around the car and starting with the lowest possible point of entry, the bottoms of the doors, until you find water coming into the car.
Next to electrical problems, leaks are the most maddening. This should be covered under warranty.
Good luck,
Bob

A great idea. The only thing I would add is that it might be better to take the car to the dealer and let them try it! Water and electricity? Scary.
Drive happy,

I used to work at automobile assembly plant body shop. It sounds like something went wrong with the robot that dispenses sealer on the assembly line. When sheet metal is welded together in this area of the vehicle, a bead of sealant is sandwiched between the sheets before it is welded. Often times, the robots fault and apply sealer off location, too thin, too thick, etc. This can happen because of various reasons.

I'd take it to the dealership so that they can find the location of the missing sealer & re-seal it.

No water in mine - thank goodness - but soon after delivery I checked to see if the spare was there and found a strange yellow spider sitting on it. I didn't recognise it and wonder if it had travelled all the way from Japan.

The place I do get water is on the rear seat whenever I open a rear door. A few large drops always detach from the top of the door and fall inwards. I can't see any way to prevent this happening.

Cheers

Yikes!! Was it still alive?

I found a giant red ant in a newspaper on my passenger seat this morning, when I was cleaning up/throwing things out. Never saw an ant that big in Florida. It was almost 3/4 of an inch long, and ... yes, mine was still alive when I tossed him and his newspaper in the trash!

Although it's possible that the ant fell onto my newspaper from the trees above, I'm planning to vacum the car out this weekend, "just in case." Maybe I should fumigate, too?

Yes, it was. Being superstitious I spared it and liberated it in the garden. It hasn't returned - yet!
