Anybody have any problems with water leaking from under the driver's side of the dash, on the left? Washed my car and found water dripping from inside the dash.

Bob,
Did you get this fixed?
What was the cause?

Nope, it hasn't happened again....yet! Very strange.

I found the source of the water leak. The leak only happened when I washed my car, it would not leak in the rain when driving or when parked in the street. I finally realized that because my drivway is on a slight slant it made a difference. I searched and searched, and after several hours I found it! The factory forgot, missed or ran out of sealer on a body joint under the windshield area on the drivers side. When in my driveway the water would run down the windshield then down onto this area under the windshield support structure, then because the car was slanted back the water would run back under this area that was missing the sealer and into the car. My car is now leak free!

No problems here.

yes I did, on my 2005 Coupe. Factory problem with poor sealing on the firewall inside the engine compartment.
Had to take it back to the dealer to have the work done.

I had the same water leak problem regarding my 2012 C6 Grand Sport. The leak would occur primarily during heavy driving rain storms when the car was parked on my slightly elevated driveway. A continuous dripping would take place under the dashboard close to the footrest.

Yes I had the same problem.
