NHTSA Complaint #10662675 — 2007 BUICK LUCERNE

I WAS DRIVING DOWN STREET AND MOTOR QUIT RUNNING. THE MOTOR DID START AND I CONTINUED ON MY JOURNEY. LATER THAT SAME DAY, THE ENGINE STOPPED AGAIN AND WOULD NOT RESTART FOR SEVERAL MINUTE. AFTER SEVERAL TRIES IT STARTED. I DID NOT HAVE ANY MORE OCCURRENCES FOR SEVERAL MONTHS. I RECEIVED A NOTICE THAT MY BUICK HAD BEEN RECALLED, BUT THAT PARTS WERE NOT AVAILABLE. IN A LETTER DATED SEPTEMBER 2014, I WAS NOTIFIED TO CONTACT MY DEALER AND PARTS WERE NOW AVAILABLE FOR GM RECALL 14299. I CALLED THE DEALER AND THEY SAID PARTS WERE NOT AVAILABLE AND THEY WOULD CALL ME WHEN THEY WERE AVAILABLE. AFTER SEVERAL WEEKS, I CALLED AND THEY HAD THE PART AND SCHEDULED ME FOR NOV. 17. I TOOK THE BUICK IN WITH FOUR KEYS. THEY WOULD ONLY FIX TWO KEYS; SO, NOW I HAVE TWO FIXED KEYS AND TWO UNFIXED KEYS FOR THE CAR. ON DECEMBER 4, THE ENGINE QUIT ON ME AGAIN AND WOULD NOT RESTART. I TRIED MOVING THE GEAR SHIFT, BUT THAT DID NOT HELP. AFTER SEVERAL MINUTES THE CAR DID START AND HAS BEEN TROUBLE FREE SINCE THAT TIME. WHEN THE ENGINE WOULD NOT START, ALL OTHER ELECTRICAL ITEMS SEEMED TO WORK, BUT THE STARTER WOULD NOT CRANK. I TOOK THE CAR TO A MECHANIC, BUT HE COULD NOT FIND A PROBLEM BECAUSE THE CAR WAS WORKING FINE AT THAT TIME. I AM CONCERNED THAT THE ENGINE WILL STOP WHILE ON THE HIGHWAY OR IN HEAVY TRAFFIC IN A DANGEROUS SITUATION. WHAT CAN I DO ABOUT THIS? *TR
