Water leaking into KH laser Hatchback

Question edited for clarity, add maker.
Question moved to model category.

Based on our research the RAV4s with wet floors are usually, but not always, clogged sunroof drains or drain outlets. Other RAV4 owners found that the body trim surrounding their windshield or even the fender panel had degraded and failed, allowing water to seep in during heavy rain.

You need to find the conduits for rain - one of them has a leak in it probably from corrosion. Try to locate just where the water is getting in and see if you can use a sealer to stop the water from getting in.

I would remove the glove box and anything else in the way and look for the source when hosing down the car.

IF IT WAS HAPPENING ALL THE TIME WATER IN THE PASSENGER FLOOR I WOULD HAVE HEATER CORE CHECKED BUT ONLY WHEN RAINS YOU HAVE A SEAL MISSING UNDER HOOD AGAINST FIRE WALL
SOME TIMES YOU CAN BUY REPLACEMENT ONES AT ADVANCE OR AUTOZONE BUT 2000 MODEL NOT SURE

many of these 04-06 durangos have a leak problem at the top of the windshield on passenger side which leads to water getting into the passenger kickpanel where the amplifier is located. I had my windshield replaced for a crack and there was rust forming behind the top passenger side of windshield...( same with the rear hatch above the passenger side of the chrome molding that covers the handle. My radio went on and off depending on when it rained. Now it doesn't work at all. I plan to check for fuses related to the amp tonight to decipher whether the fuse just blew or that the amp was fried from the water.

Have you been adding any coolant? You could have a leaking heater core, which will usually leak to the inside, wetting the carpets in the well. Most American cars locate the heater core on the passenger side of the firewall, so a leak will typically show up on only the passenger side floor. I once had an Audi that had the heater core mounted just about dead center on the firewall. When it started leaking, both sides of the well(s) got wet.

I have the same problem and I just bought this car! Very frustrating as I bought the extended toyota warranty and am being told water leaks aren't covered under warranty. If you figure out where the leak is coming from please email me at [email protected]. My leak only happens when it rains very, very hard. Is yours this way too?

check drain tube

either the gasket seal around the back hatch is worn or the light assembly has a bad gasket and water is coming around the light .the window may be leaking

Check the seal around the hatch. It is most likely worn or torn causing the leak.

Have someone remove cowl or cover to access cabin air filter box area, and clean it out good. Build up of leaves & other debris has been known to cause leaks inside because of drainage plugged.
