I was on the freeway when I herd a big "bang" like a rock hit my car. It seems to come from the roof area.
I stopped the car and looked but I could no see any evidence of a hit. By the noise and the speed of the car I thought I would have a lot of damage.

When I got home and turned the engine off, again a noise but not as loud.

This was a week ago and nothing happened since.

I was thinking to take the truck to the dealer but I would not know where to have them started.

Any ideas will be welcome. I have a 500 with almost all the options including air suspension (I thought this might be the problem but it is working).

 

Without other symptoms it's hard to know where to start. A cracking windshield can make that noise, but you would have noticed that.

 

No crack window and the sound was more metallic. One thing I noticed, before the Big Bang when the car was parked for a while, opening and closing the doors made the suspension to make a whoosh sound, which I been told is normal.
Now, it does not but I can raise and lower the car so I think the system is working.
