    Design defect - Water leaking into back seat

    After not having my car for 6 days, the dealer finally was able to recreate the leak. It turned out to be water building up in the door sill and spilling over into the back seat where there is a small indentation in the door. After looking at the door seals, they concluded that it was a design defect and there was nothing they could do about it. They are talking to Porsche. Since it only happened on the passenger-side, I was a little skeptical.

    So, I asked my friend to come over tonight and we tried it on his car. The exact same thing happened. They were right.

    If you wash you car on about a 30 degree uphill incline, you might want to limit the amount of water you use near the passenger door and check your backseat. I'd be curious if anybody else is interested in testing their car. I'll let you know how they eventually fix it.

    Re: Design defect - Water leaking into back seat

    Interesting. So I'm assuming if you reversed your car into the driveway before washing, it wouldn't be a problem?

    Anyway, that's whacky. It would seem like some added weather stripping would fix it. Let us know.

    Re: Design defect - Water leaking into back seat

    Here's what you do. Squeeze some RTV silicone onto the area of the door frame that you suspect has the gap. Apply some lubricant (anti-stick) to the area of the weather strip you suspect. Shut door and leave closed a day or two until silicone is cured. Open door and examine contours of the silicone to ascertain if moving the car's weather strip in any direction is a plausible fix. If a fix sems possible by moving the weather strip slightly, you can move or re-seat weather strip slightly by backing it with..., RTV silicone! Just an idea.

    You could also weld the doors shut. It worked for Bo and Luke.

    Now THAT's funny

    Re: Design defect - Water leaking into back seat

    Shouldn't both doors (passenger and driver) design in the same way?

    Everybody's car leaks?

    I thought the driver's side should leak also, but I couldn't get it to leak. I noticed the water seemed to flow more freely from under the door. It gives me hope that the fix won't be too difficult.

    Can somebody else try on their car to see if it leaks also and let us know?

    Re: Everybody's car leaks?
