Problems with 2007 Buick Lucerne VISIBILITY

I was driving down the highway and for no apparent reason, my sunroof exploded and shattered into tiny pieces. the noise was like a gunshot and glass came into the car because the visor was open at the time. i did not lose control of the car, but the noise did cause me to be distracted and disoriented for a short time. if there had been more traffic, it might have been a lot worse. i can not attribute the event to any weather condition or vehicle use condition. *tr

Windshield defroster safety complaint: i have a new 2007 lucerne and i just used it for the first time in a snowfall. unfortunately, the windshield defroster is aimed above the wiper blades, which means that there is no defrosting of the windshield below the wiper blades. as the snow is wiped downwards from the windshield by the blades, it results in the formation of a large clump of ice forming immediately below the wipers, to which the wipers then freeze solid to the ice. since the windshield defroster is aimed above the wiper blades, the ice cannot melt! this is an extremely dangerous situation, because the wiper blades then get coated with ice, freeze to the windshield and will not defrost while they are in their parked position because the defroster is aimed above this parked point. in fact, my friend who also an identical lucerne, just experienced the sudden breakage of the washer fluid line on the wiper blade when the wiper broke free of this ice mass. this is poor design for sure and a real safety hazard! *jb
