NHTSA Complaint #10763722 — 2008 CADILLAC DTS

ON 9/4/15 @ APPROX 5:45 P.M, VEHICLE WOULD NOT START - IT ACTED LIKE THERE WAS NO FUEL GETTING TO THE INJECTORS. THREE HOURS LATER I TRIED TO START THE CAR AND IT STARTED JUST FINE; TOOK IT FOR A DRIVE AROUND THE BLOCK W/O ANY ISSUES. ON 9/7/15 THE PROBLEM RESURFACED; I HAD THE CAR TOWED TO A LOCAL MECHANIC WHO DIAGNOSED THE PROBLEM ON 9,/8/15, TO BE A BAD FUEL PUMP RELAY. CAR WORKED FINE FOR ONE DAY; ON 9/9/15 THE PROBLEM RESURFACED ONCE AGAIN - IF THE CAR SAT OFF FOR A COUPLE OF HOURS THE PROBLEM WOULD GO AWAY. I TOOK THE CAR TO THE BUICK GMC DEALER AND THEY DIAGNOSED THE ROOT CAUSE TO BE A BAD FUSE BOX ASSEMBLY ($318 PART). THE FUEL PUMP RELAY GOT HOT ENOUGH TO MELT THE HARD PLASTIC OF THE FUSE BOX ASSEMBLY, AND THERE ARE BURN MARKS ON THE BODY OF THE FUEL PUMP RELAY - I HAVE THE OLD PARTS AND PICTURES OF SAME. THE SERVICE REP AT THE BUICK GMC DEALER SAID THEY HAVE SEEN THIS PROBLEM ON BUICK LACROSSE. BEING THAT THE FUSE BOX IS UNDER THE REAR SEAT OF THE CAR, THERE IS THE POTENTIAL FOR THE CAR TO CATCH ON FIRE.
