YOu need to check to see if your sunroof drains are clogged. 9 times out of 10 this is the problem.

 

if your windshield has been replaced they probably didnt seal it correctly or check in your engine make sure all the drains around battery are clean. from what ive heard the water builds up in there and it can get in your car. might wanna check the seal where the engine computer is located.. and do what jest said..

That use to happen to me but when i got my windshield replaced it stopped..
