Tampa resident Michele Laney says she was driving down Bruce B. Downs Blvd. when it happened. This driver thought someone fired a shotgun blast near her car until she looked up. Laney said there was a big gaping hole where the sunroof use to be and glass scattered everywhere.

Laney took the 2015 Mercedes C300 to the dealer for an inspection. She says the dealer confirmed it was a defect in the glass.

We found close to 30 similar complaints in the National Highway Traffic Safety Administration's database but there are hundreds of reports in the system from drivers who say it also happened to them.

The type of glass used in sunroof windows can shatter into thousands of tiny shards without warning. Both Audi and Hyundai have issued recalls for some models over similar issues.

Mercedes paid to replace the sunroof and repair the damage to Laney's car. They did not respond to our emails asking for a comment regarding other cases we found.

You can also call your dealer and ask if laminated glass which cracks but rarely shatters was used for the sunroof in your particular vehicle.
