I have some rather strange problem. One morning couple of weeks ago I found my car with slightly (3-4 inches) open sunroof and front windows. Few days ago it happened again and this time some rain got in, luckily not much. I am absolutely sure I did not touch roof controls on both occasions, and I had the key with me all the time. So far nothing terrible happened, I am just afraid it could happen again and lead to some real water damage. Any ideas what could cause such a glitch?
