NHTSA complaint #11325952, filed 2020-05, 50 miles“We were driving in the freeway and suddenly we heard like a bang sound, like an explosion. We looked around us and wondered what it was. Then we heard the air from the roof seeping through and we took an exit, it was a shattered sunroof. Since the rain is in the forecast and we were going on a cross country vacation, we used a flex tape to prevent for the glass to keep shattering and from the rain.”
