Stopped on the road, the rear window exploded with a very loud boom. I pulled over and talked to the driver behind me who also pulled over and asked if he saw anything, he said no, only heard the boom. We looked in the back of the car and no projectile or foreign object. I moved to a nearby parking lot and pushed as much of the broken glass into the car as I could so it wouldn't fall off on the road. There were no cracks or defects identifiable before hand. The car was clean and any issues would have been visible. There was no warning of the explosion. I have brought the car in to the dealer, Fletcher Jones in Chicago.
