What owners report most
Structure
“The sunroof glass exploded while driving down the road at 45 mph. I was not near any trees, have anyone driving in front of me, nor under/by an overpass for something to fall on the roof. The car is garage kept so limited exposure to elements. Apparently, this is not an uncommon issue for the Infiniti. Sounded like a gun going off when it exploded and rained glass down the back of the car. Fortunately, I had the sunroof shield closed and was not showered by the exploding glass.”
