WITHIN THE FIRST YEAR OF BUYING MY AVEO I HAD TO REPLACE HEADLIGHTS 10X I KEPT TAKING THE CAR IN TO GET CHECKED AND THEY SAID IT WAS FINE, THEN ONE TIME THEY SAID JUST NEEDED A BETTER FUSE (THE CHANGED IT) WORKED FOR ABOUT A YEAR THEN SIGNAL LIGHTS KEPT GOING OUT, THEN TAIL LIGHTS. THOUGHT THERE WAS SHORT TOOK CAR IN FEW TIMES THEY SAID NOTHING WRONG. TIRED OF TAKING THE CAR IN, I AM A VERY BUSY PERSON. SO WE HAVE BEEN DEALING WITH THIS PROBLEM FOR ABOUT 6-7 YEARS NOW THE DASH LIGHTS HAVE COMPLETELY GONE OUT NOW AND WON'T COME BACK ON, LEAVING US WITH 1 HEADLIGHT, 1 TAIL LIGHT AND ONLY OCCASIONAL REAR SIGNALS. AND ALWAYS SMELLS LIGHT WIRES BURNING. IN SEPT OF 2014 WE RECEIVED A LETTER RECALLING THE CAR FOR LIGHTING PROBLEMS AND STILL NOTHING ABOUT GETTING FIXED!!! THIS IS ONLY ONE OF MANY COMPLAINTS FOR THIS CAR. *JS

MY 05 AVEO,IS INCLUDED IN THE GM RECALL#A140093/NHTSA RECALL#14V261(HEADLAMP SWITCH & DRL). I HAVE BEEN EXPERIENCING ISSUES WITH ALL OF MY EXTERNAL LIGHTS (MY GAUGE CLUSTER AND SHIFTER LIGHTS HAVE BEEN OUT). I WAS REPLACING EVERY EXTERNAL BULB EVERY FEW WEEKS TO KEEP THE LIGHTS ON. THAT IS NOT WORKING. I AM DOWN TO ONE HEADLIGHT (DRIVER SIDE) WORKING ' AS FAR AS RUNNING LIGHTS GO. I HAVE NO TAILLIGHTS (BRAKELIGHTS WORK). I COMMUTE APPROX. 40MILES EACH DIRECTION FOR WORK-ALL FREEWAY. I MADE AN APPT W/CHEVY,TOOK THE DAY OFF WORK SO THE CAR COULD BE THERE ALL DAY.AS I ARRIVED TO MY APPT THE SERVICE WRITER TOLD ME THERE IS NOT A REMEDY FROM GM YET SO I WILL NEED TO COVER THE COST. EVENTUALLY WE WENT INTO THE BUILDING TO COMPLETE MY WRITE UP, AT THAT POINT I WAS TOLD THEY WERE BACKED UP ON RECALLS SO THEY MAY NOT GET TO MY VEHICLE DESPITE THE APPT. I REITERATED THE ISSUE,HE SAID OKAY,TOLD ME HE WOULD BE IN CONTACT WITH ME. AT 3:30 HE CALLED,TOLD ME THEY HADN'T HAD A CHANCE TO LOOK AT MY VEHICLE BUT WOULD GET TO IT TOMORROW. I TOOK ANOTHER DAY OFF WORK & LEFT THE CAR WITH THEM.NEXT DAY,I CALLED AT 11AM & I'M TOLD THEY HAVE YET TO TOUCH MY VEHICLE & THERE ARE ABOUT 20 CARS IN FRONT OF ME SO THEY WON'T GET TO IT TODAY EITHER.I COULD NOT LEAVE THE CAR ANOTHER DAY, I TOLD HIM I WOULD PICK IT UP. I IMMEDIATELY CALLED GM EXPLAINED THE SITUATION, THEIR RESPONSE WAS 'WHAT DO YOU WANT US TO DO ABOUT IT'. I TOLD THEM THE CAR WAS UNSAFE AND ILLEGAL TO DRIVE IN THIS CONDITION I NEEDED IT FIXED. THEY TOLD ME THEY WOULD CONTACT ANOTHER DEALERSHIP AND HAVE THEM CONTACT ME. ABOUT 20MINS LATER THE DEALERSHIP CONTACTED ME, GAVE ME THE SAME RUN AROUND AS THE FIRST DEALERSHIP.THIS RECALL IS 7MONTHS OLD, IT TOOK GM 10YRS TO ACKNOWLEDGE IT. THIS IS UNACCEPTABLE, I BOUGHT THIS CAR IN GOOD FAITH THE BASIC FUNCTIONALITY OF THE CAR WOULD WORK AND IT DOES NOT AND GM IS NOT CORRECTING THE ISSUE. *TR
