DASHBOARD CLUSTER LIGHTS BEGAN TO MALFUNCTION INTERMITTENTLY THEN AFTER TWO DAYS THEY WOULDN'T ILLUMINATE AT ALL. THE GEAR SHIFTER LIGHTS AND ONE TAIL LIGHT WERE ALSO AFFECTED. AFTER REPAIR IT WAS DETERMINED A WIRE HARNESS THAT LEADS TO THE UNDERWOOD FUSE BOX HAD MELTED SHORTING THE ELECTRICAL WIRES. HAVING SPONTANEOUSLY BURNED, THE INTERIOR AND EXTERIOR LIGHTS WOULDN'T WORK. THIS MADE IT IMPOSSIBLE TO SEE THE SPEEDOMETER, FUEL GAUGE, ENGINE FLUID MONITORING GAUGES, ETCETERA. ALSO, THE EXTERIOR LIGHTS AFFECTED MADE FOR A DANGEROUS DRIVING CONDITION AS WELL AS A TRAFFIC OFFENSE. AFTER RESEARCHING THIS I LEARNED THERE ARE MANY, MANY CASES OF EXACTLY THE SAME PROBLEM WITH EXACTLY THE SAME YEAR, MAKE, AND MODEL. *TR

I WAS DRIVING DOWN THE HIGHWAY AT 55 MPH AND THE CAR STARTED TO LOSE ACCELERATION. I PRESSED ON THE GAS AND NOTHING HAPPENED. I STARTED SLOWING VERY QUICKLY AND I PULLED OFF TO THE SIDE WHERE EVENTUALLY THE CAR COMPLETELY SHUT DOWN ALL ON ITS OWN AND THE BATTERY LIGHT CAME ON THE DASH. I TURNED THE IGNITION TO OFF AND RESTARTED THE CAR. I WAS ABLE TO KEEP GOING WITHOUT ANOTHER INCIDENT. THE NEXT DAY ON MY WAY HOME FROM WORK THE SAME THING HAPPENED AGAIN. MY CHECK ENGINE LIGHT WAS ON AT THE TIME FOR WHICH I JUST HAD MY FUEL CAP REPLACED BECAUSE IT WAS NOT LOCKING AT ALL. AFTER A FEW DAYS MY CHECK ENGINE LIGHT HAS GONE OFF. I AM SERIOUSLY CONCERNED ABOUT THIS AS THIS CAR IS MY MAIN MEANS OF TRANSPORTATION BACK AND FORTH TO WORK WHICH IS AN HOUR DRIVE FOR ME. I JUST RECENTLY PURCHASED THIS CAR (WITHIN THE LAST 3 WEEKS) FROM THE FORD DEALERSHIP IN TILLAMOOK OR AND OF COURSE THEY DID NOT REPORT ANY OF THESE ISSUES. *TR

SEVERAL CUSTOMERS HAVE HAD THIS SAME PROBLEM WITH DEFECTIVE WIRING INSIDE OF THE FUSE BOX IN WHICH THE SPLICE PACK OVERHEATS AND CAUSES WIRES TO MELT. THIS CAUSES THE ELECTRICAL SYSTEMS TO MALFUNCTION, BRAKE LIGHTS TO GO OUT, TURN SIGNALS TO STOP WORKING, DASH SAFETY INDICATORS TO FLICKER ON AND OFF, THE RADIO TO STOP WORKING, AND HEADLIGHTS TO STOP WORKING. THIS IS AN ONGOING PROBLEM THAT CHEVY DOES NOT WANT TO ADDRESS BUT IT HAS CAUSED A CAR TO STALL IN THE MIDDLE OF THE HIGHWAY AND AFFECTS SAFETY OF THE VEHICLE PASSENGERS, THE DRIVER, AND THE PASSENGERS IN OTHER VEHICLES. I FEEL THAT THE 2004-2008 CHEVY AVEO IS A PRIME CANDIDATE FOR A RECALL BECAUSE OF SAFETY ISSUES. *TR

THERE HAVE BEEN SEVERAL TIMES THE LIGHTS BLINKED OFF AND BACK ON BUT THEY ARE COMPLETELY OUT NOW. AFTER RESEARCHING SEVERAL FORUMS (EX. HTTP://CHEVROLETFORUM.COM/FORUM/SONIC-AVEO-NEW-11/DASH-LIGHTS-AVEO-20707/), I FOUND OTHER PEOPLE WHO HAD THIS SAME ISSUE. IT SEEMS THERE IS A DEFECTIVE PART IN THE ENGINE FUSE PANEL THAT CAUSES THIS ISSUE. THIS COULD BE A MAJOR CONCERN TO MANY DRIVERS BECAUSE YOU CANNOT SEE ANY OF THE DASH INSTRUMENTS INCLUDING THE SPEEDOMETER, GAS GAUGE, TACHOMETER, AND TEMPERATURE GAUGE. *TR
