So it has finally gotten hot here, hot enough to run the A/C all the time. Yesterday I'm tooling around town and put some stuff in the back seat on the floor, when I get home and take it out its soaking wet. I look on the floor and there is a puddle on my all weather mat, nothing I had was liquid so I didn't know what it could be. I pulled up the all weather mat and the floor is soaked, soaked enough I can see puddles. I used a towel to dry it up and I must have went through five towels soaking wet, wet enough I could wring them out! I attempted to dry it out as much as I could but its soaked clear through to the padding underneath. I hit it up with a hair dryer and got it some what dry, I took the car out today for a short trip and sure enough...I have puddles of water again. My only thought is that its leaking water from the vent under the seat, don't know but it's going in tomorrow, I'm dreading what they will have to do..I'm sure the front seat will have to come out..the carpet will have to come up...console will most likely have to be removed...and who knows what electrical things under there got all wet.

I presume it must have been raining really hard wherever you are. Did you by any chance leave a window or sunroof slightly opened?

BTW, where are you located?

chilledbenz

Nope no rain..been sunny for days...only real change was that the A/C has been working hard for the past day or so. Not to mention more water appeared today too after driving it in dry weather. Bit of a mystery guess I should be happy it didnt short something out and catch on fire.

This is outright craziness! Never heard of things like this happening to any car of any brand.

It sounds like a disconnected condensate hose that's allowing the water from the AC to drain into the cabin instead of outside of it. Some cars produce a large amount of water even on short drives.

Good luck getting this repaired.

There is a drain plug clogged someplace, likely with leaves or something. But don't think it is in the interior, the water ended up there because the force of acceleration of the car pushes the water to the rear most egress point - the heater vent below the rear seat.

Look under the hood, along the firewall, look for any area clogged with leaves, that would prevent vertical draining.

bring it to the dealer, you probably have a a/c drain hose that is off or kinked causing the a/c to drain in the car. It will be covered under warranty if that is the case.

benggolf

Yes, I agree. If rain is not in the equation, a disconnected condensation drain hose is the likely culprit here. Good luck with the repairs and hope the dealer gets to dry your carpets well, otherwise you car will start smelling "fishy".

Oh its going back to the dealer tomorrow morning...and I'm going to make sure the carpet is deep cleaned or at the least the padding underneath is replaced. Don't need this thing rusting out on me, its bad enough it has enough rattles and creaks that it sounds like a five year old car, doesn't need to look like one too. I just hope all the electronics under there are fine, don't need stuff to short out or up and stop working on me.

maybe your trunk monkey was having a pool party!

...I swear, I was just reading ;-)

Turns out it was a missing drain plug that was most likely either left out at the factory or didn't get put in very well and fell out durring the time I've had it. When the A/C really started kicking up because of the hot weather, all the water drained into my back floor board. Good news is everything electrical seems fine and I pray it doesn't smell like an old moldy bathroom when it sits in the sun all day (although they claim they are going to shampoo it all out and if it does smell replace all the carpet and padding). Sad part about this story is they checked the computer and it seems I'm not the first to have this happen.....guess I got to be the first one to post it on this board.

Just to update this story, I have the car back. According to the service sheet they had to remove the bottom of the dash, the drivers seat, driver and rear drivers side kick panel trim and the carpet. They replaced the faulty plug and replaced the soaked sound deading foam. It gets better, turns out someone else had the exact same problem this week according to a company exec...two in the same week..whats the chances?

Was your car a german build? That's the way these things go - you get a pattern developing on the assembly line, and its always a cluster of cars that have the defect. I see the same thing in the semiconductor industry - the defects always come in "bunches".

chilledbenz

Yeah it was built in Germany so can't blame it on the plant in South Africa ha ha. From the looks of it this week must have been a busy week for MB service departments, my problem makes four different instances on this board this week. Up until now it seems this car had been pretty bullet proof.
