My wife was driving on the highway and the back lift glass blew off the tailgate and hit a motorcyclist he was not injured but there was some damage to his bike. The insurance company will not cover the repairs to the glass and the dealer said that there is no recall for the glass so I have to pay for replacement out of pocket. When I went to the glass place the guy told me the same thing happen with his SUV and the dealer said they had to update his lift glass with bolts instead of the glue that was originally used when manufactured.
