I have a fuel smell in the cabin of my car which started about 3 weeks ago. I have drove the car a couple of times and it was pretty bad, also my sunroof almost blew off the car while driving to dry the car after removing the salt from the streets after the snow. I have since parked it in the garage to avoid any further damage. I will submit pictures so you can see the sunroof.

During a drive, I had the sunroof opened and then it suddenly started raining. When I tried to close the sunroof using the button, it wouldn't budge. I had to continue driving on the highway with rain pouring inside the vehicle. When I finally found a place to stop and check the sunroof, I saw that the roof on one side was popped off. After a few minutes of trying to close it, it finally popped back into place on its own. However, now there is a rattling sound coming from the sunroof when driving, and the car is no longer quiet. I can hear outside noise as if a window is cracked opened. Every time the sunroof opens and close there-??s a slight popping sound on that side and looks like it is still out of place.

Sun roof fix glass flew off of vehicles in traffic while I was driving on a busy highway. Adhesive glue failed to keep the part attached.
