  DRIVING OVER A BRIDGE OVER WATER,A LOUD EXPLOSION HAPPENED.AT FIRST I DID NOT KNOW WHAT IT WAS,UNTIL I HEARD WIND BLOWING FROM THE MOON ROOF AREA.THE GLASS ON THE ROOF EXPLODED AND SENT GLASS DOWN WARD.LUCKILY I HAD THE MOON ROOF SHADE CLOSED OR THE GLASS WOULD HAVE CAME DOWN ON ME.I NEARLY LOST CONTROL. THE WEATHER WAS DRY WITH A OVERCAST SKY. THE TRAFFIC WAS VERY LIGHT.IT WAS NOT POSSIBLE FOR ANY FOREIGN MATTER TO HIT THE GLASS.I AMMEDIATELY DROVE THE VEHICLE TO THE GMC,WHERE I PURCHASED IT.( DIXIE BUICK GMC).MY VEHICLE ONLY HAS 2040 MILES ON IT.THIS WAS A SATURDAY AND THE SERVICE DEPT. WAS CLOSED. SPOKE TO THE SALES MANAGER,WHO SAID HE NEVER SEEN ANYTHING LIKE THIS BEFORE. HE GAVE ME A LOANER CAR TO USE. THE SERVICE DEPT. CALLED ON MONDAY,AND STATED THAT THE WAS NO DEFECT,AND I OR MY INSURANCE CO, WOULD HAVE TO PAY. I CALLED GMC CUSTOMER SUPPORT AND THEY STATED THAT THEY WOULD DO WHAT THE SERVICE DEPT. SAID.SO THEY WILL NOT COVER IT.FINALLY TODAY I CALLED MY INSURANCE CO. AND LOOKS LIKE THEY ALSO WILL NOT COVER IT.I'AM STILL WAITING FOR A FINAL DECISION FROM STATE FARM INS.MY VEHICLE WAS TRAVELING SOUTH ON INTERSTATE 75 IN SOUTH WEST FLORIDA IN FT. MYERS.

  FUEL/PROPULSION SYSTEM

  THIS CAR, A 2018 GMC TERRAIN IS EQUIPPED WITH AUTO START / STOP, A STANDARD FEATURE THAT TURNS OFF THE ENGINE WHEN BRAKE IS APPLIED, SUCH AS AT A STOP LIGHT. THE ENGINE TURNS OFF WHILE BRIEFLY STOPPED AT A STOP SIGN. THIS IS DANGEROUS AND A SAFETY ISSUE. WHILE ATTEMPTING TO PULL INTO A TRAFFIC LANE WITH THE ENGINE OFF, I HAVE EXPERIENCED AN UNSAFE LAG BEFORE THE ENGINE RESTARTS. GM HAS STATED, THE ENGINE CAN BE TURNED BACK ON BY REMOVING YOUR FOOT BRIEFLY FROM THE BRAKE PEDAL. SERIOUSLY ??? WHILE BEHIND ANOTHER VEHICLE, I WILL NOT FOLLOW THIS PROCEDURE. I HAVE NO CONFIDENCE THE ENGINE WILL RESTART AND LUNGE FORWARD, STRIKING THE VEHICLE AHEAD. I WANT GM TO PROVIDE THE CAPABILITY TO PROVIDE THE DRIVER THE ABILITY TO ENABLE OR DISABLE AUTO START / STOP. THE FEATURE IS ALSO TOUTED AS SAVING FUEL WHILE STOPPED. PERHAPS A TINY AMOUNT WHILE AT A LONG LIGHT OR TRAIN CROSSING. CERTAINLY NOT AT A STOP SIGN OR STOPPED BEHIND ANOTHER VEHICLE.
