I was driving only 30mph through my suburban neighborhood bringing my kids to school in the morning when a loud shotgun sound hit my car causing me to be distracted and distraught. My entire sunroof had exploded on me for no reason. Mercedes is currently undergoing a class action lawsuit for this. But since it is not completely yet, Iâm being told I need to pay $3700 out of pocket for the default damages and servals days without a vehicle.
