Yes I had the same problem.
Tried using some silicone sealant at the base of the windshield on the driver's side but it didn't help, the leak continued. It got to the point that I carried a plastic paint roller tray in the back of the car and I would place it on the floor under the dashboard on the drivers side if it looked like it was going to rain.
I noticed that when the car was on flat level ground the leaking stopped. But when parked on an uphill grade the leaking returned.
Took the car to my dealer but he couldn't locate the cause of the leak. He felt that it was probably the result of the firewall sealant not sealing completely.
Lately it hasn't been a problem, but I still don't park on inclines if it is raining. And I still have the paint tray in the back, just in case.
