I BOUGHT TRUCK CERTIFIED BY CARL'S BUICK GMC. JAN 30TH 2014 WITH 40 SOMETHING THOUSAND MILES, ALSO PAID 5K FOR EXTENDED WARRANTY. ALTERNATOR WENT BAD, SERVICE DEPARTMENT SUCKS, AND ALSO HAD THEM CHECK MY DASH BC CRACKS STARTED, AND DEEMED DEFECTIVE BY SERVICE MANAGER BC TRUCK KEPT LIKE NEW, I ONLY DRIVE ON TRIP TO FAMILY AND DR'S, I'M HANDICAPPED, I PD CASH. AND CHARGED ME THRU EXTENDED WARRANTY, IF THE AIR BAGS GO OFF PC OF DASH GOING EVERYWHERE. NO WAY EVERYONE HAS SAME EXACT CRACKS AND TROUBLE WITH MY MOTOR BURNING OIL WHICH IS CHANGED BEFORE REALLY DUE, CALIPERS LOCKED UP, AND BURNT UP ABS WIRING, AND I FORGOT I WENT THROUGH 3 ALTERNATOR BEFORE FIXED AN HAVING ISSUES AGAIN. I PAY THIS MUCH AS A GOOD GM CUSTOMER AND THIS IS HOW WE'RE GOING TO BE TREATED. I'M NOT O.K. WITH THIS.
