    I just picked up a 2008 and it probably had something like yours happen or at least the previous people tried to fix the leak since there is new seam sealer around all the seams of the trunk. I seam sealed the usual spots around the top of the hatch but still had a leak. I found one seam below the right tail light just behind the bumper where there was little sealer and it had split. That was where the majority of it was coming in. The rubber gaskets on the tail light side of the bolts were also shot so I replaced those too. Waiting another 15 minutes to try the water test again.

    I have nothing to complain about, it is a 2008 with 120k on it for $5k and a three year, unlimited mile warranty on the hybrid battery from a local one man dealer that we (my daughter) have bought two other cars from. The others were a Sienna and a Hybrid Camry. Both in great shape for a good price.

    After sealing those two on each side my trunk is now bone dry. I didn't see this area anywhere else on the web.

    I’ve used the sealant mentioned before, and it’s still dry as a bone.

    Hi Don I have the same exact leak on my 2008 prius and I also sealed all the roof rail common leak places. did the taillight seal fix the problem? did you find the source?

    Eluo, good thinking, but this is not the problem. I had my son hose water over the tailgate while I was sitting inside the trunk and I saw water seeping in the same location as Don. your problem happens only when the car is moving and if you are missing the fender piece.

    I had a guy that does body work take a look and he thinks I need to replace the foam gasket behind the headlights and behind the bumper.

    What would you get from Home Depot for making the gasket?

    I bought a ebay rear tail light assy and it leaked really bad along the bottom edge. I bet the body shop bought cheapies and not the oems.

    I just found water in my spare tire well after getting a flat.

    No noticeable smells from standing water, but there was probably an inch of water in there.

    Been rainy here lately and I also just recently replaced the hatch struts. New ones are very strong and the hatch will come to a violent stop on full open if you don't hold it. I believe I may have the issues others have found with the body seems under the roof rain gutters opening up. Will post results of sealing these when I get to it.

    Take battery out there’s a rubber plug in the bottom of the well

    If car lives outside just drill a weep hole through it if garaged like mine just take the plug out.

    Same for the under the spare tire.

    If car lives outside check the cabin air filer for mice activity.

    First time ever, found water in wheel well and below the 12v a couple of weeks ago. Pulled the two plugs and let the areas dry while I caulked everything up and down the channels. Not a pretty job. I have trouble holding my right hand steady since an accident a year ago, but, even though it looks somewhat chunky and choppy, it should seal O.K. Have not checked to see if it worked, yet.

    Oh, and I KNOW the leak must be of recent origin, as I had to use the spare about 45 days ago, and there was NO water in wheel well and it had been raining here pretty hard and pretty steady for weeks at that time.

    Anyway, getting those plugs out is the big thing.

    You actually do not need to take the battery out, you can access the plug from under the car. Just make sure not to touch the exhaust system if it is at all warm. A needle-nose ViseGrip and a small flathead screwdriver helped on that task.

    So here's my story, probably not many people look at these anymore. About 3 weeks or so ago, I went to a local used car lot to purchase a 2004 Toyota Corolla. When I got there, they said, well someone's already put a down payment on that one, but we've got some other ones in your price range. I ended up settling on a 2009 Prius. It's my first hybrid and also the first time I've ever went to an actual car lot to purchase a vehicle, I've always either bought from an individual person or when I was a teenager, my dad bought me cars and I would pay him the money for the loan. SO, needless to say, I think I've been swindled. I noticed it was making an audible sound and it didn't sound bad, but like something was kicking on and off periodically when it shouldn't be, sort of a mechanical whirring sound that repeats every minute or so. From what I've read on other forum posts, I'm concerned it may be the brake actuator...but, I digress. The car had been driving fine other than that, no issues - except we got a few warning lights, various ones. The check engine, ABS, brake, VSBC all came on - again leading me to the possible brake actuator issue - we've reset them and so far they haven't come back. But then, suddenly, I went to go get in my car on my lunch break and tried to start it, and all the lights flashed (including the red triangle of death) and it refused to start. After that, I tried it two or three more times - it just wouldn't do anything. No lights, no way to get it to Ready, no dash lights, head lights, nothing. So I figured, well maybe it's the 12v battery - again, after reading other posts, thinking it probably just needed to be replaced. My boyfriend managed to get a new one for a decent price...but when he pulled everything out from the trunk area to replace the battery, he found something interesting (and scary). Pooled water where the spare tire well is, and pooled water where the battery is!!! I have owned many, many older cars in my life, but have never seen anything like that in my life. He also noticed that you could hear liquid sloshing around in the battery - he said maybe it could be water, too? But not sure. AND, clearly the previous owner had had an issue with it, because you can see some sort of seal (it actually looks like weld, but I'm not an expert) all around the spare tire area, plus around where the battery is, you can see what looks like some other type of sealant - possibly even wood glue, as it was a dingy brown-yellowish color, but we're not sure either. This was one area we did not think to check when we bought the car, but I did notice there was a slight mustiness in the car and chalked it up to it sitting on the dealer's lot for a while before we bought it. I was concerned enough as it was with the possibly brake actuator problem, but this...this is a new one for me. I'm at a loss. Other than this issue, the car is a dream to drive - the suspension is in great shape and it just glides around, I like the back-up camera, I'm happy with everything else so far. The motor seems to be in good shape, it's just stupid to me that something like this could be an issue. I think Toyota should do a recall, as there is no easy way to fix this. Luckily, I work with a girl who's boyfriend welds, so I may be able to get him to touch up any hairline cracks in the body welds, and if there are other problematic areas, I was thinking about using some sealant available to me for free here at work, it's called Solar Seal and it's a 25-year terpolymer sealant used typically when our techs do repairs to houses because of damage from nuisance wildlife. Either way, I'm pretty upset. I hope I don't have to resort to pulling out the spare tire and the battery just to mop up standing water every so often. And of course (just my luck), we're expecting heavy storms here in my city in the next few days. I just feel like I'm doomed to always have problems with cars like this, I can't afford to pay $300 - $500 a month to buy a brand new car or one with a warranty. And I can't afford to be without a car entirely, even though I live about a half mile from where I work and used to take the bus every day. It's just so frustrating - I specifically wanted to buy a Toyota because I've had multiple GM cars with serious issues (Oldsmobile Aurora - bad seals in the motor causing blown repeated blown head gaskets / manifold intake gaskets, cavaliers with same issue with head gaskets blowing, etc.) I thought Toyota would be manufactured better. I understand welds will eventually fail but I've never, ever seen it happen in a car? do not know. Just wanted to share my story - maybe I can successfully find the problem area and seal it well enough to prevent this from happening again.

    Nothing unusual for a GEN II Prius. I will admit, I did not read your entire post, because being one big block of copy without any paragraphs was a bit daunting.

    You basically need to pull the plugs in the spare compartment, as well as the one under the battery to let water drain out.

    You need to open the hatch and seal all along,,,,several threads on here about how to do it, as well as a lot of YouTube vids.

    No big deal. You did not get cheated, as far I can tell.

    Mine leaked like that, too. Turned out the ingress was from where left side roof panel met left side rear body panel - under the trim piece, the seal was cracked. Sealed it and no more leaks. For sure drain the water. do not know about the noises and check-lights.
