I was in a vehicle accident on March 30. A accident that could have been avoided if the horn on the IS350 2021 was louder. The vehicle that collided into my vehicle was a Dodge Ram that was hauling a travel trailer which was what hit me. I tried honking various times to let the driver know that I was present and that they were merging onto my lane and I believe due to the weak sound of the horns installed in these vehicles the driver of the other car did not hear my warnings and collided into me.

The sunroof exploded while driving on a freeway. No rocks were involved, very loud explosion. Sun shade was closed, which prevented glass from getting inside car.
