1. MULTIPLE TIMES, MY DRIVER SIDE DOOR LOCK HAS COMPLETELY FALLEN INTO THE DOOR. I HAVE PROBABLY HAD THIS ISSUE "REPAIRED" FIVE TO SIX TIMES, BY BOTH THE CHEVROLET DEALER WHERE I BOUGHT THE CAR, AS WELL AS MY OWN MECHANIC. 2. THINGS THAT WERE WRONG WHEN WE FIRST BROUGHT THE CAR TO THE DEALER FOR REPAIRS IN EARLY APRIL 2014. THIS IS THE LIST WE GAVE THEM, MODIFIED FOR SPACE: *CLOCK A COUPLE YEARS AGO, THE CLOCK IN MY CAR STOPPED WORKING. OFTEN, THE CLOCK WOULD READ 1:00 WHEN I TURNED THE CAR ON, NO MATTER WHAT TIME IT WAS. SOMETIMES, IT WOULD RANDOMLY DISPLAY ANOTHER TIME. EVENTUALLY, IT JUST STOPPED TURNING ON ALTOGETHER. *CD PLAYER THREE TIMES, THE RADIO AND/OR CD PLAYER HAVE TURNED ON AND OFF BY THEMSELVES. THIS HAS NOT HAPPENED RECENTLY. THE CD PLAYER SOMETIMES WORKS JUST FINE. OTHER TIMES, IT DOES NOT. WHEN IT DOES NOT WORK, IT DOES ONE OF TWO THINGS. IT WILL EITHER SPIN AND SPIN AND SPIN AND THEN SPIT THE CD OUT, OR, MORE OFTEN, IT WILL READ ?ERROR 7.? I DO NOT KNOW IF THE LATTER IS CONNECTED TO THE OTHER ISSUES DESCRIBED HERE, BUT THE FORMER (THE TURNING ON AND OFF) PROBABLY IS. DAYTIME RUNNING LIGHTS THE DAYTIME RUNNING LIGHTS NO LONGER WORK. MY REGULAR MECHANIC TRIED REPLACING THE BULBS, BUT NEW BULBS DID NOT SOLVE THE PROBLEM. I MUST MANUALLY TURN THE LIGHTS ON. REVERSE LIGHTS SOMETIMES THE REVERSE LIGHTS COME ON WHEN I PUT THE CAR IN REVERSE. SOMETIMES, THEY DO NOT TURN ON WHEN I PUT THE CAR IN REVERSE. INTERIOR LIGHTS/GAUGES ABOUT 10 DAYS AGO, ALL THE INTERIOR LIGHTS AND GAUGE LIGHTS STOPPED TURNING ON, EVEN WHEN I MANUALLY TURN THE HEADLIGHTS ON. THE CAR INTERIOR IS COMPLETELY DARK. FOG LIGHTS I BELIEVE THESE MIGHT NOT BE WORKING EITHER. INTERIOR DOME LIGHT THE INTERIOR DOME LIGHT BURNED OUT. MY REGULAR MECHANIC REPLACED THE BULB, AND THAT FIXED THE PROBLEM. RIGHT TAIL LIGHT THE RIGHT TAIL LIGHT IS OUT. *TR

THE ENTIRE LOCK OF THE DRIVER SIDE DOOR FELL INSIDE THE DOOR WHEN I TRIED TO UNLOCK MY DOOR. FIRST I TRIED TO FIX THE PROBLEM MYSELF, BUT SIMPLY COULD NOT REPAIR THE PROBLEM. HOWEVER, I RESEARCHED THE ISSUE ONLINE AND SAW THAT MANY, MANY OTHERS HAVE ENCOUNTERED THE SAME PROBLEM BEFORE WITH THIS MODEL. NATURALLY, BECAUSE I WOULD LIKE TO BE ABLE TO LOCK MY CAR DOOR, I TOOK IT IN AND HAD IT FIXED FOR $160. THE CUSTOMER SERVICE REP JUST SMIRKED WHEN I TOLD HIM WHAT HAPPENED AND SAID THAT WE MUST'VE PUSHED THE KEY IN TOO HARD "OR SOMETHING LIKE THAT". I WAS NOT HAPPY ABOUT THE COST, BUT I PAID. HOWEVER, JUST TWO WEEKS LATER, THE SAME PROBLEM OCCURRED WITH THE PASSENGER SIDE DOOR, WHICH I RARELY UNLOCK WITH THE KEY. APPARENTLY THE DEALER DOES NOT KNOW WHAT CAUSES THE PROBLEM. FORTUNATELY I WAS ABLE TO FIX IT MYSELF THIS TIME BUT HAD TO TAKE THE DOOR APART, BUT IT WAS TIME CONSUMING. IT IS VEXING TO ME THAT CHEVROLET MUST REALIZE THERE IS A PROBLEM, BUT DOES NOT SEEM TO WANT TO FIX IT. *TR

SUN, ALL THE GAUGES GO UP THEN BACK DOWN. ~ THIS 2005 CHEVROLET AVEO LT HATCHBACK, IS HAVING MORE AND MORE ELECTRICAL PROBLEMS BUT THE DEALER, ROSNER CHEVROLET, REFUSES TO FIX THE PROBLEM WITHOUT A CHARGE, SINCE THE VEHICLE IS NOT A FIRE HAZARD OR ON A RECALL LIST. ~ I FEEL AS THOUGH GM AND THE DEALER, ARE HIDING SERIOUS ELECTRICAL ISSUES FROM THE BUYER EITHER DUE THE COST OF REPAIRING THE PROBLEM OR DUE TO SOME OF THE MANUFACTURING BEING DONE IN SOUTH KOREA. OR UNTIL PEOPLE START DYING FROM THESE PROBLEMS. ( OR UNTIL WE START GETTING LAWYERS ). *TR
