I have a 2006 highlander, about a year old. Just started having problems with a undetectable leak. Under my carpet is soaked, top of the carpet is dry. Toyota says I must have left my windows open, I have never left windows open. The only leak they found was a tiny one under the dash. I have a Hybrid, the only reason we found there was water under the carpet is; the vehicle cut off and then would not crank. They checked the hybrid batteries under the back seat and discovered the computer between the 2 batteries was covered with water, and it had shorted out. I feel this is a manufacturer's defect,something is leaking, perhaps in the weather stripping around the windows or etc....so check under your carpet to see if it's wet. It does cause a musty odor.

The most logical and frequent cause of this is a misaligned or clogged drain from the air conditioning condensation.
Second would be a clogged drain from the sunroof.

THERE IS WATER UNDER MY CARPET. CHECKED THE AIR, AND SUNROOF DRAINS, BOTH ARE FINE.

When we had water under the carpet in a 1987 Nova (aka Corolla built in California) the culprit was the A/C drain. The A/C worked fine. But most of the water was draining into the passenger compartment rather than onto the pavement because the end of the drain hose was twisted out of position. (Dealer-installed of course.) Check again for a partial plug or break, as the previous response suggested.
You're right about the windows not being left open. If that was the problem, you'd have water everywhere. Not just under the carpet.

I had the same problem with another car (Jetta) the problem was a small break in the seal around the windshield causing puddles in the rear seat area. This could only be fixed with a windshield replacement as the seals could not be replaced. Just a suggestion of another possible solution to the problem. By the way I have an 01 4x2 with a 4 cylinder and still love it after 72,000 miles.

I have the same thing, and it has been in the dealership for FOUR DAYS now. It was a bad front driver's side wheel bearing hub, which subsequentially became a bad ALB sensor (sometimes it can be removed from the old hub and placed on the new, sometimes not), which in turn caused a problem with the backing plate -- they wouldn't tell me why other than they are not charging me for that part. My Highlander has 94,000 miles on it, with 30K added in the last year.
The sound was related to speed at 25-60 MPH...kind of a "whu-whu-whu-whu" sound, equally felt under my feet on the floor board (since it is on the front in my case).

Good point, bjosephs. I heard about someone else with the windshield seal problem. It seems strange to me that the water would puddle in the rear seat area, but that's what this other guy reported too.

Has anyone had the evaporator unit in their 2001 Highlander replaced? Or can anyone tell me how to replace it? How much of the dash needs to be removed?

Thanks for all replies!
The problem was indeed a bad right front wheel bearing and bearing hub. It was fixed in 2 hours (and almost $500) at a local Toyota dealer. The mechanic tried to convince me that the left bearing also required replacement, since he claimed that most of the noise and vibration was coming from the left side. I authorized repairs to the right side only, and now the problem is gone!

one toyota hybrid owner in texas had a leak as you describe after a heavy rain with the car outside. water had gotten into the chips under the rear cargo area that control the main batteries. needless to say it was covered under warranty but would have ben expensive if not. they found that the weather stripping in the rear hatch was improperly installed.
