NHTSA Complaint #11499314 — 2017 HONDA PILOT

We drove from Grand Rapids, Michigan to Alexandria, Virginia on 12/27. About 20 minutes from our destination, we exited the highway onto the parkway and as we were going about 15-18mph on an exit ramp, the closed sun roof imploded. There were no trees, bridges, or even other cars (due to it being near 10pm) nearby to cause this from falling debris. There is no impact site- just a broken roof. It was terrifying and I nearly drove off the road from the sound (my husband and 2 children 9 and 11 were also in the car.) The only reason I did not crash the Pilot was due to the fact that I am pretty cool headed- it took us an additional 20 minutes of driving with an unknown state on the top of the roof to discover what had happened due to the fact that there was no way to exit or pull off the parkway. We validated that there was no bridge (aka no one was able to throw something off and onto to the top of the car) and the night was mostly clear. If it was an item it would have to be "part of a plane or a meteor" And no item came through or damaged the closed sun shade for the roof. We took pictures of the glass and have to have it replaced today since we are on a road trip and have to be able to drive this vehicle home before New Years. It is also parked outside and we have to get the roof re-sealed before it rains. I am spending $700+ out of pocket to put a used sunroof on the pilot to be able to get this home (which probably has the same glass defect). The shop is going to do this today and I will have them take additional photos. There were no warning lights, our car is kept in the garage at home and rarely parked outside. It has never been in hail and we do very light highway driving (it is almost entirely city driving in our day to day lives).
