NHTSA Complaint #10682810 — 2008 BUICK LACROSSE

I TURNED THE KEY IN THE IGNITION TO START THE CAR. IMMEDIATELY, A VERY LARGE ROAR ( LIKE AN AIRPLANE) OCCURRED JUST AS THE ENGINE STARTED. I TURNED OFF THE IGNITION FEARFUL OF DAMAGE TO THE ENGINE, NOT KNOWING WHAT MIGHT HAPPEN. IT WOULD NOT RESTART. IT WAS TOWED TO THE DEALERSHIP TO HAVE IT REPAIRED. THE IGNITION COIL HAD RUPTURED, IGNITION MODULE WAS KNOCKED OUT. THE COST FOR REPAIR: $800+. TWO WEEKS LATER, THE ENGINE LIGHT LIT UP ON THE DASH BOARD DISPLAY. I RETURNED TO THE DEALERSHIP FOR INVESTIGATION. THE SECOND REPAIR DIAGNOSIS REPAIR REQUIRED THE REPLACEMENT OF THE FUEL PUMP, THE OIL PRESSURE SENDER PUMP AND THE AIR INJECTOR PUMP ( NO CHARGE FOR THIS). COST: $1004.81. WHEN I TRIED TO DRIVE IT HOME, THE ENGINE LIGHT LIT UP AGAIN SO I RETURNED TO THE DEALERSHIP. THIS TIME THERE WAS A NEED TO REPLACE A EMISSION VALVE.( NO CHARGE). FIVE DAYS LATER, THE ENGINE LIGHT LIT UP AGAIN. DIAGNOSIS: CODE PO411, AIR INJECTOR PUMP MALFUNCTION. WILL SCHEDULE REPAIR NEXT WEEK ( FEBRUARY 14-21) THIS IGNITION COIL MALFUNCTION CAUSED ELECTRICAL FAILURES TO ELECTRONIC MODULE, THE FUEL PUMP, THE AIR INJECTOR PUMP, THE OIL PRESSURE PUMP AND THE EMISSION VALVE SO FAR, AT GREAT COST TO THE CONSUMER. MORE IMPORTANTLY, THE FEAR IS THAT THE IGNITION COIL RUPTURE AND RESULTING FAILURE COULD HAVE CAUSED AN ENGINE FIRE. THE SOUND WAS DEAFENING AND FELT LIKE AN EXPLOSION. I HAVE NEVER EXPERIENCED THIS KIND OF PROBLEM WITH ANY OTHER OF MY AUTOMOBILES. IT WAS A FRIGHTENING EXPERIENCE. *TR
