2016 BUICK REGAL WITH 11K MIKES. THE WINDSHIELD RECENTLY DEVELOPED A CRACK IN THE LEFT LOWER CORNER. THE CRACK STARTED AT THE BOTTOM EDGE (BELOW THE DASH) ABOUT 8 INCHES FROM THE LOWER LEFT CORNER. OVER SEVERAL DAYS, THE CRACK SLOWLY SPREAD UP AND TO THE LEFT, ENDING AT THE LEFT EDGE OF THE WINDSHIELD ABOUT 6 INCHES FROM THE LOWER LEFT CORNER. THE CRACK IS IN THE INNER LAMINATED GLASS ONLY. VEHICLE WAS TAKEN TO A BUICK DEALER TO SEE IF THE WINDSHIELD CAN BE REPLACED UNDER WARRANTY. THE SERVICE ADVISOR CLAIMED IT WAS A STRESS CRACK, BUT WANTED TO CHECK WITH THE GM ZONE REP. BEFORE PROCEEDING. GM ZONE REP. DENIED THE WARRANTY CLAIM BECAUSE HE FELT SOMETHING HIT THE WINDSHIELD CAUSING THE CRACK. THE WINDSHIELD HAS NO SIGNS OF ANY IMPACT ON IT. THE GM ZONE REP. NEVER ACTUALLY INSPECTED THE CAR. VEHICLE WAS ALSO TAKEN A GLASS SHOP FOR THEIR OPINION. THE GLASS SHOP CLAIMED THE CRACK WAS CAUSED BY EITHER A DEFECT IN THE WINDSHIELD OR IMPROPER INSTALLATION. APPARENTLY IS MAY BE A KNOWN ISSUE ON 2013-2014 BUICK REGALS.

WHEN BACKING OUT OF A DARK AREA (SUCH AS A GARAGE) INTO BRIGHT LIGHT, OR WHEN LEAVING A DARK TUNNEL INTO BRIGHT LIGHT, THE BACKUP DISPLAY OR FORWARD NAVIGATION DISPLAY BECOME UNUSABLE DUE TO CONTRAST ("WASHOUT") ISSUES. THE SYSTEM IN THE BUICK IS A SINGLE SENSOR SYSTEM (IT ALSO CONTROLS THE AUTOMATIC HEAD LIGHTS) THAT REQUIRES 20-30 SECONDS TO ADJUST CONTRAST AFTER A TRANSITION FROM DARK TO LIGHT. THIS 20-30 SECOND DELAY IS CRITICAL WHEN BACKING UP BECAUSE YOU LOSE THE VIEW OFFERED BY THE REVIEW CAMERA UNLESS YOU STOP WHILE THE SYSTEM ADJUSTS. THERE ARE MANY SITUATIONS WHERE YOU CAN'T STOP BACKING (ESPECIALLY FOR 30 SECONDS) ONCE YOU HAVE STARTED. THE "WASHOUT" OF THE DISPLAY WHEN USING THE NAVIGATION MAP IS ALSO A POTENTIAL SAFETY ISSUE. IF TRYING TO FOLLOW THE MAP/DIRECTIONS WHEN EXITING A TUNNEL (THE TUNNEL IS DARK ENOUGH TO REQUIRE THE AUTO HEADLIGHTS TO TURN ON) YOU LOSE THE ABILITY TO SEE THE MAP FOR 20-30 SECONDS WHILE THE SYSTEM ADJUSTS TO THE CHANGE IN LIGHTING. AT THE VERY LEAST THIS CAUSES A DISTRACTION FOR THE DRIVER TRYING TO FOLLOW THE MAP. BUICK TOUTS THE BACKUP CAMERA AND THE BIG NAVIGATION DISPLAY AS VEHICLE SAFETY AIDS, BUT THE IMPLEMENTATION IS FLAWED AND A DANGER TO THE DRIVER OR OTHERS.
