2006 Buick Lucerne Fuel System Problems

VEHICLE IS A 2006 BUICK LUCERNE CX WITH 40,000 MILES. ABOUT 2 MONTHS AGO IT STARTED TO GO DEAD WITHOUT ANY WARNING. THE FIRST OCCURRENCE WAS JAN 15, 2014 WITH MY WIFE DRIVING. THE NEXT SHUTDOWN ON MAR 4, 2014, OCCURRED IN RUSH HOUR TRAFFIC. THERE WAS AN AUDIBLE SIGNAL ACCOMPANIED BY A "SERVICE TRACTION CONTROL" WARNING, FOLLOWED IMMEDIATELY BY A THROTTLE CONTROL WARNING AND COMPLETE ENGINE SHUTDOWN. I WAS ABLE TO COAST ACROSS 2 TRAFFIC LANES INTO A PARKING AREA WITH GREAT DIFFICULTY WHILE STEERING AND BRAKING WITHOUT POWER ASSIST. TRIED TO RESTART THE ENGINE BUT GOT ?THROTTLE DISABLED? MESSAGE. AFTER 2-4 MINUTES WAS ABLE TO RESTART WITH NO WARNING LIGHT ILLUMINATED. THE LAST SHUTDOWN WAS ON MARCH 10, 2014, ON THE INTERSTATE AT 70 MPH. I HAD DISABLED TRACTION CONTROL EARLIER IN HOPES OF AVOIDING ANOTHER UNEXPECTED SHUTDOWN. AFTER COASTING OFF THE INTERSTATE, I WAS ABLE TO RESTART NORMALLY AFTER A FEW MINUTES. NO WARNING LIGHTS APPEARED AFTER THE RESTART. TWO GM DEALERS CHECKED THE CAR ON MAR 11, 2014. THE FIRST WAS A CHEVROLET DEALER, AND AFTER SOME DIAGNOSTIC WORK THEY SENT ME TO A BUICK DEALER DOWN THE STREET. BOTH DEALERS SAID THERE WERE NO ERROR MESSAGES AND THEY COULD NOT REPAIR. THEY SAID WHEN IT HAPPENS AGAIN TO BRING IT BACK IN IMMEDIATELY FOR DIAGNOSIS. THE 3 SHUTDOWNS HAVE BEEN ON COLD MORNINGS, TEMPS LESS THAN 40 DEGREES. I BELIEVE IN ALL THREE CASES THE WARNING ?WATCH FOR ICY CONDITIONS? HAS APPEARED PRIOR TO FAILURE. THIS IS AN EXTREMELY DANGEROUS FAILURE MODE THAT LEAVES NO TRACKS IF THERE IS AN ACCIDENT! MY WIFE NOW REFUSES TO DRIVE THE CAR, AND I AM VERY APPREHENSIVE ABOUT IT. *TR

2006 BUICK LUCERNE . CONSUMER WRITES IN REGARDS TO A RUSTED GAS LINE ON VEHICLE. *SMD THE CONSUMER STATED A COUPLE OF WEEKS AGO, HE NOTICED A PETROLEUM ORDER AND NO SIGN OF LEAKING EVIDENCE ON THE GROUND UNDER THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER, WHERE THEY ADVISED HIM NOT DRIVE THE CAR, DUE TO A FUEL LEAK WHICH WAS CAUSED BY RUSTED FUEL AND EVAP LINES.

I OWN A 2006 BUICK LUCERNE. THE VEHICLE SLOWS AS IF IT IS GOING TO STALL AND CUT OFF, IT PICKS UP SPEED ON ITS OWN ,AND WHEN STOPPING THE VEHICLE CUTS OFF. IT PRESENTS A SAFETY HAZARD IN THAT MOST OF MY TRAVELING IS DONE VIA THE EXPRESSWAY. WHEN THE CAR SLOWS DOWN I AM AT THE MERCY OF THE DRIVER BEHIND ME. IF HE IS GOING TOO FAST AND TAIL GATES THEN I AM SURE TO BE REAR-ENDED. I HAVE TAKEN THIS CAR TO THE DEALERSHIP FIVE TIMES,AND THEY COULD NOT DUPLICATE THE PROBLEM. DIAGNOSTICS SHOWED NOTHING. SERVICE DEPARTMENT MANAGER DROVE VEHICLE WHILE IN SHOP FOR FIFTH TIME AND EXPERIENCED THE PROBLEM. BECAUSE DIAGNOSTICS STILL DOESN'T RECOGNIZE A PROBLEM HE SAYS THEY ARE HAVING TO CALL IN AN EXPERT TO DETERMINE THE PROBLEM. THE CAR HAS BEEN IN AND OUT OF SHOP SINCE APRIL 3, 2007, AND EACH TIME THE ENGINEERS FROM GM SUPPOSEDLY WERE IN CONSULTATION WITH SERVICE DEPARTMENT. THIS PROBLEM OCCURS RANDOMLY WITH NO WARNING. HELP!*AK

DT*: THE CONTACT STATED WHILE SETTING THE CRUISE CONTROL THE VEHICLE SURGES FORWARD 5 TO 7 MPH. DUE TO THIS PROBLEM THE VEHICLE TAKES 15 TO 30 SECONDS TO RETURN TO THE SET SPEED. THIS IS AN INTERMITTENT PROBLEM THAT OCCURS UNDER ALL DRIVING CONDITIONS. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION, WHERE IT WAS DETERMINED THIS WAS THE WAY THE VEHICLE WAS DESIGNED. UPDATED 7/11/2006 - DRIVER'S SIDE MIRROR FOGGED UP. THE FUEL GAUGE WOULD MOVE TO FULL. WIND WAS COMING THROUGH THE SIDE OF THE WINDSHIELD. THE LIGHT TO ILLUMINATE THE INSTRUMENT PANEL WERE NOT BRIGHT ENOUGH. *NM
