2008 Buick Lacrosse

THE FUEL LEVEL SENSOR LOCATED IN THE GAS TANK HAS FAILED THREE TIMES IN THE PAST THREE YEARS. EACH TIME THE DEALER HAS REPLACED THE FUEL LEVEL SENSOR. THIS HAS OCCURRED FIRST IN DEC. 2008 (7574 MILES), THEN NOV. 2009 (21145 MILES), AND NOW DEC. 2010 (37344 MILES). THE SERVICE TECH AT THE DEALERSHIP INFORMED ME THAT THIS PROBLEM IS FAIRLY COMMON (IN FACT, WHEN I TOOK THE CAR IN FOR REPAIR THIS TIME, THERE WAS A PONTIAC AZTEC WITH THE SAME PROBLEM BEING REPAIRED). THE TECH ALSO TOLD ME THAT THE CAUSE IS SULFUR IN THE GAS CAUSING THE SMALL WIRES IN THE SENSOR TO CORRODE AND EVENTUALLY BREAK. THE MODULE ERROR CODE ERROR IS P0463.

TL*THE CONTACT OWNS A 2008 BUICK LACROSSE. WHILE DRIVING AN UNKNOWN SPEED, THE CONTACT STATED THAT THE LIGHTS ON THE INSTRUMENT PANEL SUDDENLY BEGAN TO DIM BEFORE THEY EVENTUALLY SHUT OFF. THE LIGHTS TURNED BACK ON. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER BUT THE FAILURE COULD NOT BE DIAGNOSED. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 30,400 AND THE CURRENT MILEAGE WAS 30,500.

REMOTE, REMOTE STARTER (RKE) FOB FOR CAR STOPPED WORKING PROPERLY. REPLACED BATTERIES EVEN THOUGH DIC DID NOT SHOW BATTERIES NEEDED CHANGING. THIS MAYBE A PROBLEM ALSO. SOMETIMES IT WORKS, SOMETIMES IT DOESN'T. WORKED PERFECTLY FINE, THEN PROBLEMS STARTED. 99% OF THE TIME IT WILL NOT START THE CAR. 50% OF THE TIME IT WILL OR WILL NOT, LOCK OR UNLOCK CAR. I HAVE TRIED RESETTING AND/OR PERSONALIZING KEYS & FOB THROUGH DIC CENTER. CAR WILL SOUND HORN TO SHOW IT HAS BEEN RESET PROPERLY, BUT ISN'T. STILL DOES NOT WORK PROPERLY ALSO WHEN USING RKE, THE DOOR LOCK KNOB WILL NOT COME UP ALL THE WAY AND THE DOOR IS NOT UNLOCKED. ALSO, THE DOOR LICK KNOW WILL NOT GO DOWN ALL THE WAY IF I USE THE RKE FOB. IF I USE THE KEY TO UNLOCK THE DOOR, THE DOOR KNOB WILL COME UP ALL THE WAY AND THE DOOR WILL UNLOCK. IF I USE THE RKE FOB TO LOCK THE DOOR, THE DOOR KNOB WILL NOT GO DOWN ALL THE WAY AND THE DOOR WILL NOT BE LOCKED. I HAVE TRIED USING THE FOB AWAY FROM ALL POSSIBLE INTERFERENCE WHICH I DO NOT THINK IS THE PROBLEMS, IT STILL ONLY WORKS SOMETIMES. *TR

TL*THE CONTACT OWNS A 2008 BUICK LACROSSE. THE CONTACT STATED THAT WHEN DRIVING UPHILL WITH THE CRUISE CONTROL ACTIVATED, THE VEHICLE WOULD BEGIN TO ACCELERATE AT A FAST RATE. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALERSHIP WHERE THE CONTACT WAS TOLD THERE WERE NO PROBLEMS WITH THE CRUISE CONTROL. THE FAILURE MILEAGE WAS 25. THE CURRENT MILEAGE WAS APPROXIMATELY 20,000. UPDATED 08/03/10. *LJ UPDATED 09/21/10

I HAVE A 2008 BUICK LACROSSE CXL WHICH I PURCHASED 04/29/2008. AT ABOUT 3,000 MILES I NOTICED THE PASSENGER AIR BAG LIGHT WOULD COME ON INTERMITTENTLY SHOWING THE BAG WAS OFF EVEN THOUGH MY WIFE WAS IN THE SEAT AND BUCKLED UP. I TOOK THE UNIT INTO THE LOCAL DEALER AND THE SERVICE ADVISOR TOLD THEY COULDN'T CHECK FOR A CODE UNLESS THE "OFF" LIGHT WAS SHOWING WHEN SOMEONE WAS IN THE SEAT. LATER THE INDICATOR LAMP STARTED COMING ON AND WOULD STAY ON (SHOWING THE AIR BAG WAS OFF) FOR MILES. I RETURNED TO THE DEALER I PURCHASED THE CAR FROM AND THEY CHECKED ALL CONNECTORS AND PINS. IT DID NOT MALFUNCTION WHEN THEY TEST DROVE THE VEHICLE BUT THE MALFUNCTION RETURNED ON THE WAY HOME. THIS DEALER HAS RECHECKED THE VEHICLE TWO TIMES TO NO AVAIL, THE LIGHT STILL COMES ON. I HAVE FOUND IF I HAVE MY WIFE MOVE THE SEAT FORWARD AND/OR BACKWARD THE LIGHT WILL GO OF FOR A WHILE, (THE TIME VARIES WITH THE ROAD CONDITIONS E.G. ROUGH, SMOOTH, STRAIGHT, CURVY AND SO FORTH). I FOUND ANOTHER INSTANCE ON LINE WHERE A 2009 LACROSSE HAD THE SAME PROBLEM AS MINE. A FIX WAS NOT PROVIDED IN THEIR INVESTIGATION OF THE VEHICLE. BUICK DOESN'T LIST ANY TECHNICAL BULLETINS PERTAINING TO THIS MALFUNCTION. THIS IS A VERY DIS-CONCERNING ISSUE ANY TIME WE DRIVE AND I SUPPOSE IT IS A SAFETY ISSUE ALSO. *TR
