2006 Pontiac Grand Prix Electrical System Problems

My headlights quit working while I was driving with no warning

Unknown

YOU CAN TURN THE KEY ON AND HAVE COMPLETE POWER INSIDE THE CAR THE DASH EVERYTHING BUT NO POWER TO THE MOTOR. THEN YOU CAN SOMETIMES TURN THE KEY AND THE CAR WILL HAVE THREE TO FIVE SECOND DELAY CRANKING. OR YOU CAN TURN THE KEY OFF AND THERE'S A 3 5 SECOND DELAY IN THE CAR DYING. YOU CAN BE GOING DOWN THE ROAD AND THE CAR WILL DIE. IT TAKES IT 5 TO 45 MINUTES TO CRANK. MY FRIEND WHO IS AN ELECTRICAL ENGINEER FIGURED OUT THE ISSUE AND ADDED A NEW WIRE TO SUPPLY POWER TO THE MOTOR. THERE IS AN ELECTRICAL ISSUE WITH THE KEY IGNITION. I NEED THIS FIXED. I HAVE A TWO-YEAR-OLD GRANDSON AND I DOORDASH. IT HAPPENS CONSTANTLY. *TR

MY 2006 PONTIAC GRAND PRIX EXPERIENCES HEADLAMPS TURNING OFF WITHOUT WARNING WHILE THE VEHICLE IS IN MOTION, AND NOT BEING ABLE TO GET THEM TO TURN BACK ON AGAIN. I DRIVE COUNTRY ROADS HOME FROM WORK AT NIGHT WHERE THERE ARE NO STREETLIGHTS AND THE SPEED LIMIT IS 45-50 MPH. THIS IS A SERIOUS SAFETY HAZARD ! ! ! IT IS SOCIALLY IRRESPONSIBLE FOR GM TO IGNORE THIS ISSUE. FOR SOME REASON 2006 PONTIAC GRAND PRIX IS NOT PART OF GMS PRODUCT SAFETY RECALL (RECALL NUMBER: 14291 WHICH ONLY REPLACES THE HEADLAMP DRIVER MODULE HDM FUSE). I HAVE HAD TO REPLACE THE HDM RELAY TWICE ALREADY, WHICH ONLY LASTS FOR ABOUT 4 MONTHS BEFORE BURNING OUT AGAIN. OBVIOUSLY THE PROBLEM IS NOT JUST WITH THE FUSE BUT LIKELY WITH THE ELECTRICAL WIRING OR THE FUSE BOX ITSELF. THIS SERIOUS PROBLEM MUST BE INVESTIGATED MORE THOROUGHLY BEFORE SOMEBODY IS KILLED. I DID READ THAT 2006 PONTIAC GRAND PRIX WAS OFFERED AN EXTENDED WARRANTY PROGRAM FOR PROBLEMS STEMMING FROM THE HEADLAMP MODULES FOR 12 YEARS OR 150,000 MILES, WHICHEVER HAPPENS FIRST. UNFORTUNATELY, THE HEADLAMP PROBLEM JUST BEGAN FOR ME IN 2019 AT WHICH POINT THE CAR WAS 13 YRS OLD AND WAS NOT COVERED BY THE EXTENDED WARRANTY PROGRAM OR THE SAFETY RECALL, WHICH IS SIMPLY ABSURD ! AT THE VERY LEAST GM SHOULD NOW INCLUDE THE 2006 PONTIAC GRAND PRIX MODEL IN THE 14291 PRODUCT SAFETY RECALL. BUT GM REALLY NEEDS TO RELEASE A PERMANENT FIX FOR THE PROBLEM RATHER THAN A TEMPORARY FUSE REPLACEMENT EVERY COUPLE MONTHS. HAS ANYONE INVESTIGATED IF THESE OVERHEATED HEADLAMP DRIVER MODULE RELAYS HAVE CAUSED ELECTRICAL FIRES OR MELTED THE UNDER HOOD BUSSED FUSEBOX? IF GM IS NOT WILLING TO STEP UP AND TAKE RESPONSIBILITY, I HOPE WE CONSUMERS CAN COUNT ON THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA) OFFICE OF DEFECTS INVESTIGATION (ODI) TO FORCE GM TO DO THE RIGHT THING. THANK YOU IN ADVANCE FOR LOOKING INTO THIS SERIOUS MATTER.

MY GRANDPARENT GAVE ME THE CAR A FEW YEARS AGO, AND I LOST POWER TO ALL FUNCTIONS OF HEADLIGHTS. I COULD NOT TURN THEM AT ALL, WHETHER THE CAR WAS STATIONARY OR MOVING. I THEN REPLACED A FUSE THAT FIXED THE PROBLEM BRIEFLY. AFTER AWHILE, MY HEADLIGHTS BEGAN TO STAY ON AFTER I HAVE SHUT THE CAR OFF. DURING THIS TIME, MY HIGH BEAMS WERE THE ONLY FUNCTION THAT WORKED. DUE TO THIS ONGOING PROBLEM, I HAVE HAD TO REPLACE MULTIPLE BATTERIES AT LEAST THREE TIMES. I HAVE DONE RESEARCH AND THE 2007 GRAND PRIX MODELS WERE RECALLED FOR THIS SAME EXACT ISSUE. IFM ASKING THAT GM EXTENT THE RECALL TO THE 2006 MODEL YEAR SO THIS ISSUE, THAT I HAVE DEALING WITH FOR YEARS, CAN FINALLY BE RESOLVED.

KEY TURNS OVER BUT WON'T START

TL* THE CONTACT OWNS A 2006 PONTIAC GRAND PRIX. AFTER THE VEHICLE WAS SHIFTED INTO THE ON POSITION, ALL THE WARNING INDICATORS ILLUMINATED. UPON INSPECTION OF THE HOOD, THE CONTACT NOTICED BLACK SMOKE COMING FROM THE ENGINE COMPARTMENT. THE FIRE DEPARTMENT WAS CONTACTED AND EXTINGUISHED THE FIRE. THE VEHICLE WAS TOWED TO BETTEN BAKER CHEVROLET, BUICK, GMC (14120 NORTH LAND DR, BIG RAPIDS, MI) WHERE IT WAS DIAGNOSED THAT THE FUSE BOX AND ENGINE ASSEMBLY WOULD HAVE TO BE REPLACED. THE MANUFACTURER WAS CONTACTED REGARDING THE FAILURE AND OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 182,000. *LN UPDATED 7/17/18*JB *TR

HEADLIGHTS STARTED OFF JUMPING WHEN DRIVING. THEN WHEN PARKED STARTING CAR SOMETIMES HEADLIGHTS WOULD COME ON AND TIMES IT WOULD NOT. I WOULD HAVE TO TURN ON HIGH BEAMS TO GET HEADLIGHTS ON TO STAY ON. THEN THAT DIDN'T WORK ANY MORE. NOW HEADLIGHTS ARE GONE AND DASH BOARD LIGHT ARE ALSO OUT.

LOW BEAMS DON'T WORK INLESS THEY WANT TO N THE LEFT TURN SIGNAL DON'T WORK

AFTER A FEW MINUTES OF DRIVING THE LOW BEAM LIGHTS WILL TURN OFF AND CANNOT BE TURNED BACK ON. HIGH BEAMS WILL WORK, BUT LOW BEAMS CEASE TO OPERATE WITHOUT WARNING. PROBLEM OCCURS RANDOMLY, OPERATING FINE ONE DAY AND TURNING OFF WITHOUT WARNING AT OTHER UNPREDICTABLE TIME FRAME.

TL* THE CONTACT OWNS A 2006 PONTIAC GRAND PRIX. THE CONTACT STATED THAT THE VEHICLE WAS HAVING AN ELECTRICAL SWITCH MALFUNCTION, WHICH AFFECTED THE TURN SIGNALS AND HEADLIGHTS. WHEN THE DRIVER SIDE TURN SIGNAL SWITCH WAS ACTIVATED, THE HIGH BEAM HEADLIGHTS AUTOMATICALLY ACTIVATED. WHEN THE ENGINE WAS TURNED OFF, THE HEADLIGHTS AUTOMATICALLY ACTIVATED, FORCING THE CONTACT TO DISCONNECT THE BATTERY IN THE VEHICLE. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 200,000.

MY LOW BEAMS WILL GO OUT WITHOUT ANY WARNING, NOT CONSISTENT. THIS HAPPENS ON HIGHWAY OR CITY. THEY WILL COME BACK AFTER A FEW MINUTES, OR SOMETIMES DAYS. I STILL HAVE HIGH BEAMS

TL* THE CONTACT OWNS A 2006 PONTIAC GRAND PRIX. WHILE DRIVING APPROXIMATELY 45 MPH, THE BATTERY WARNING INDICATOR ILLUMINATED AND WHITE SMOKE APPEARED FROM THE HOOD. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 228,000. THE VIN WAS NOT PROVIDED.

HEADLIGHTS GO OUT WHEN DRIVING. NORMALLY AT NIGHT TIME AND WHEN TRAVELING ABOVE 40 MILES PER HOUR THIS HAS BEEN GOING ON FOR OVER 24 MONTHS AND IT HAS STARTED TO GET MORE FREQUENT OVER THE LAST 6 MONTHS.(NOT SURE THIS IS BECAUSE OF MORE NIGHT TIME DRIVING I HAVE BEEN DOING] THIS IS A SERIOUS SAFETY HAZARD I AM NOW SPENDING $580 ON A COMPUTER ISSUE AND ON TOP OF ALL THE OTHER ISSUES TO DEAL WITH>I AM HOPING THIS SOLVES THE PROBLEM

I HAVE BEEN HAVING STARTUP ISSUES WITH MY CAR. WHEN TRYING TO START THE CAR, IT MAKES A CLICKING SOUND AND WILL NOT TURN ON. I HAVE TO JUMP START MY CAR WITB A HALO PORTABLE CHARGER, EVERY SINGLE TIME I WANT TO DRIVE IT. SOMETIMES MY CAR CUTS OFF AND LOSES POWER WHILE I'M DRIVING WHICH HAS ALMOST CAUSED ME AN ACCIDENT TWICE! MY CAR HAS RANDOMLY CUT OFF IN MOTION WHILE I WAS ON THE HIGHWAY, APPROACHING AN INTERSECTION, AND ON A RURAL ROAD IN ANOTHER CITY. I HAVE CALLED BEFORE AND WAS TOLD TO FILE A COMPLAINT ONLINE. THIS ISSUE STARTED HAPPENING A YEAR AGO BUT ONLY OCCASIONALLY. NOW THIS HAPPENS FREQUENTLY. I ASSUMED I HAD A BAD BATTERY OR ALTERNATOR OR STARTER, SO I REPLACED ALL THREE PARTS, INCLUDING SPARK PLUGS, WIRES AND AIR FILTERS. I'M STILL HAVING THE SAME ISSUE AND NEED THIS RESOLVED. I NEED TRANSPORTATION TO GET TO AND FROM WORK AND DO NOT DEEL SAFE DRIVING IT ESPECIALLY DURING THE WINTER MONTHS, WHEN IT RANDOMLY CUTS OFF. PLEASE HELP RESOLVE THIS ISSUE. I AM A LONG TIME PONTIAC OWNER AND DO NOT WANT TO GET RID OF A FULLY PAID FOR CAR IF THE ISSUE CAN BE RESOLVED BY YOUR COMPANY.

CAR HAS BEEN CONTINUALLY OVERHEATING, RADIATOR HAS BEEN FLUSHED AND REFILLED WITH FRESH COOLANT AND NEW THERMOSTAT WAS BLED. CAR IS FINE WHILE DRIVING OVER 50MPH BUT OVERHEATS WHEN IN TRAFFIC AT A LIGHT. DRIVER BACK WINDOW MOTOR IS OUT, THE WINDOW GOES DOWN BUT WON'T GO UP. THE CAR STOPPED ABRUPTLY WHILE DRIVING AND HAD TO PULL ON THE SIDE DON'T KNOW WHAT HAPPENED BUT IT WON'T START UP BUT THE LIGHTS COME ON INSIDE THE VEHICLE. I HAVE HAD TROUBLE SINCE PURCHASING THIS VEHICLE. GM NEEDS TO TAKE THIS VEHICLES COMPLETELY OFF THE ROAD THEY HAVE STOP MAKING THEM AND I CAN SEE WHY THEY'RE NOTHING BUT MONEY EATERS.
