I am running up against this exact issue myself right now. Dealer will not cover it under warranty and wants to charge $180 an hour to blow out the rear drains.

I'm right now trying to figure out where the drain actually comes out. From my research both after taking apart stuff and diagrams it dumps somewhere in the middle of the car ( hence why it pours out everywhere under the rockers). The reason it soaks the belt is because 2 of the drains collect into a single large pan then that pan has a tube that goes to the body. When it backs up the pan overflows and pow- you got water overflowing on the seat belt and into the car.

I'm going to pull off the side panel of the car and see if I can access the drain exit. It's really just a giant pain in the ***.

I don't think that you will see much when you pull off the side of the car, I didn't look for the drain when I had mine off (no problem with it, so not thinking of it), but I think that the catch pan and tube may be inside the engine compartment...

Mine is a 2013, with less than 14k miles. I'm the 2nd owner, so I don't know much about the prior history except it is a New York car and was probably a lease. It's been garage kept since i've owned it though. Like you should do with a Porsche haha

Thanks for the posted photo's and information, I am going to look for mine and see how difficult this is to do, keeping the drains running clean is a good plan...

This is an old thread but I'm bumping it as someone who recently ran into this problem after heavy rains in Houston. Our driver side rear drain wasn't totally clogged but clogged enough that with the heavy rain the drain overflowed into the passenger cabin on the driver's side, saturating the edges of the panel behind the seats, pooling under the driver's seat as well as soaking the carpet and padding & frying our SmartTop. The latter caused all sorts of strange behavior with our Boxster including the alarm going off and refusing to disarm, an airbag warning light, a system fault message, a soft-top control system fault message, driver's side frunk & trunk switches not working & the spoiler being stuck in the raised position. After drying everything out and uninstalling the SmartTop everything seems fine.

Keep those drains clean! If your dealer is servicing your vehicle then make sure they're clearing the drains. We just recently had ours serviced at the dealer and I find it hard to believe that this drain clogged so quickly.

Good reminder, a little prevent now save a lot of grief later! I too have the SmartTop and would hate to have it destroyed by water...

As for clogs, it is a small opening and hose, even a small leaf could plug it, a few bits of fluff and dirt and it is sealed!

^^ Not Mr. T. but I can answer a couple of questions...

Yes, the flaps open with out going into the service position, in fact they open when the top goes up and stay there. So you just need to operate the top long enough for them to open then stop. Drains are on both sides.

Good idea with the vinyl tubing, might be safer then pushing 'any' metal through the hose...

Take a look over in the DIY sub forum.....a member has a video posted that answers all this.

The dealer normally knows about the rear most drains only. Turns out there are two more that can only really be cleared by removing the rear of the side skirts and reaching in. Really bad design....combined with the fact that the end of the tubes have a screw on cover with fabric over them which seems to encourage clogging.

I have seen cars with fully clogged drains even from owners who say it never has been outside, low miles etc...

Supplying the link to that post would have been very useful...

With 5,500 posts, I'm pretty sure you can search.....not being an ***, but we are all pretty tech savy at this point.

Actually it is not always about searching, it is about seeing exactly the article or process that 'you' are referring to, especially if is a proven method.

So thanks for not being a ***
