2003 Chevrolet Monte Carlo electrical system problems

“Vehicle stalls when starting. While driving vehicle may shut off when moving on highway if you are not pushing on gas pedal. May be due to faulty EGR or emissions component”

“MY CAR IS A 2003 MONTE CARLO, IF I TRY TO USE THE DIRECTIONAL SIGNALS THEY MAKE A BUZZING SOUND AND THEN THE BRAKE LIGHT AND THE AIR BAG LIGHT COMES ON ALONG WITH THE BATTERY LIGHT, NO SIGNAL WORKS, THE HAZARD LIGHTS WORK , I REPLACED THE HAZARD SWITCH BUT THAT DIDNT SOLVE IT . BATTER IS FINE AND THE ALTERNATOR I HAD THEM CHECKED THERE IS NO RELAY FOR THE DIRECTIONALS ITS ALL IN ONE . SOMETHING IS STRANGE GOING ON I ALSO NOTICED SOMETIMES WHEN YOUR DRIVING THE THOSE THREE LIGHTS WILL START COMING ON AS WELL . I HAD PUT UP THE WINDOWS AND THEY ALL WENT ON TOO , SOMETIMES JUST WHEN DRIVING IT OR EVEN STOPPED HAD THIS CAR SINCE IT WAS BRAND NEW NEVER HAD A PROBLEM TILL A FEW WEEKS AGO”

“TL* THE CONTACT OWNS A 2003 CHEVROLET MONTE CARLO. THE CONTACT RECEIVED A RECALL NOTICE FOR NHTSA CAMPAIGN NUMBER: 14V400000 (ELECTRICAL SYSTEM). WHILE DRIVING AT UNKNOWN SPEEDS, THE KEY FAILED TO STAY IN THE IGNITION. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO CITY CHEVROLET (3040 E BUSINESS 30, COLUMBIA CITY, IN 46725, (260) 691-4899) WHERE THE RECALL REPAIR WAS COMPLETED AND DIAGNOSED THAT THE IGNITION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 194,095.”

“TL* THE CONTACT OWNS A 2003 CHEVROLET MONTE CARLO. AFTER THE VEHICLE RECEIVED AN OIL CHANGE, OIL WAS SEEN LEAKING FROM THE ENGINE. IN ADDITION, THE VEHICLE OVERHEATED, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED, AND SMOKE EMERGED FROM THE HOOD. THE CONTACT STATED THAT, AFTER REPLACING THE RADIATOR, THERE WAS A COOLANT LEAK. THE CONTACT ALSO STATED THAT THE KEY FOB FAILED TO WORK. FURTHERMORE, THE TIRES WERE REPLACED AND ROTATED, BUT THE TIRE PRESSURE WARNING INDICATOR REMAINED ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE OIL LEAK WAS DUE TO A FAULTY CATALYTIC CONVERTER. THE VEHICLE WAS NOT REPAIRED. A DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS INFORMED AND DID NOT ASSIST. THE FAILURE MILEAGE WAS 174,034.”

“WHEN I GET IN THE CAR AT TIMES AND POUT KEY IN IGNITION, THERE IS ABSOLUTELY NOTHING. THE ELECTRICAL SYSTEM IS DEAD. I HAVE TO DISCONNECT THE NEGATIVE ON THE BATTERY FOR ABOUT 2 MINUTES TO GET IT TO WORK AGAIN. I ALSO EXPERIENCE FLASHING DOME LIGHT, BRAKE LIGHT ON, IGNITION BELL RINGING WITH NOTHING IN IT, ALSO INDICATORS ON DASH PANEL, SECURITY, BATTERY, DOOR OPEN, LOW FUEL, CHANGE OIL SOON, AND THEY WILL NOT STOP SHOWING UNTIL I DISCONNECT THE BATTERY AGAIN AND SET SYSTEM. I PUT A COMPETE NEW IGNITION IN IT, BOTH THE KEY PART AND THE IGNITION BLOCK AND I STILL HAVE THIS PROBLEM. I WAS TOLD BY CHEVROLET DEALER THAT THERE IS NO WAY TO BYPASS THE SECURITY IN THIS CAR BECAUSE THERE IS A CHIP IN THE STARTER THAT PREVENTS THIS. WHEN I GET OUT OF THE CAR AND PRESS THE LOCK ON THE KEY FOB REMOTE, THE HORN BLOWS AS AN INDICATOR THAT THE CAR IS LOCKED, BUT I CAN WALK OVER AND OPEN THE DOORS EVERY TIME. THE LOCK SYSTEM FOR THE DOORS IS NOT WORKING ELECTRICALLY EITHER. I AM AT ODDS AS TO WHAT TO DO WITH THIS PROBLEM BECAUSE BEFORE I SPEND MONEY TO FIX IT, I WOULD LIKE TO KNOW WHAT IS CAUSING IT FIRST. ALL THE DEALERS WANT AT LEAST $119.00 JUST TO DIAGNOSE THE PROBLEM.…”

“A.C. CLICKS ON AND OFF, LIGHTS BLINK WHILE DRIVING, SOMETIMES DON'T WANT TO START UNLESS IT DISCONNECT BATTERY. LIGHTS ON DASH CLUSTER DON'T WORLAND SECURITY LIGHT ON”
