FOR THE LAST TWO YEARS AT RANDOM TIMES WHEN I START MY CAR, THE BRAKES WILL NOT WORK. THEY CAN NOT EVEN BE PRESSED DOWN. WHENEVER THIS HAPPENS, A CORRESPONDING WEIRD REVVING THAT CAUSES THE CAR TO LUNGE FORWARD IN SUCH A WAY THAT IT DOESN'T USUALLY ALSO HAPPENS. I PARALLEL PARK ON A STREET DAILY, AND ONE MORNING WHEN THIS HAPPENED ENDED UP HITTING THE CAR IN FRONT OF ME. USUALLY THE PROBLEM STOPS HAPPENING AFTER DRIVING FOR ABOUT 1/2 A MILE, BUT IT IS PRETTY SCARY TRYING TO DRIVE WITHOUT BRAKES TO GET TO THAT 1/2 MILE MARK. ESPECIALLY SINCE WHENEVER THE BRAKES WON'T WORK THE CAR ALSO SEEMS TO ACCELERATE ON ITS OWN. I HAVE TRIED TO GET THIS FIXED MULTIPLE TIMES BUT IT ALWAYS STOPS HAPPENING BY THE TIME I GET TO THE MECHANIC AND I'VE LEFT MY CAR OVERNIGHT AT A MECHANIC TWICE AND THEY HAVEN'T BEEN ABLE TO RECREATE THE ISSUE. I CAN'T PART WITH MY CAR FOR AN ENTIRE WEEK SO THAT THIS PROBLEM CAN BE DIAGNOSED. *TR

WONDERING IF GM DAEWOO MAY HAVE BEEN USING MULTIPLE SUBSTANDARD ELECTRICAL COMPONENTS, THE IGNITION KEYS ARE ALWAYS HOT AFTER DRIVING. IS THERE ANY POTENTIAL FOR THE IGNITIONS GOING OUT/SHORTING OUT ON THESE VEHICLES? WOULD HATE TO PARK MY CAR IN THE GARAGE AND CAUSE MY HOUSE TO BURN DOWN. *TR

MULTIPLE PROBLEMS, STARTED WITH DAYTIME LIGHTS GOING OUT, CLOCK GOING OUT AND COMING ON WITH CORRECT TIME, DEALER REPLACED CLOCK AND SAID DAYTIME LIGHTS RELATED AND SHOULD BE FIXED, IT WAS NOT. NEXT ALL THE INSTRUMENT PANEL LIGHTS WENT OUT, REPAIRED BY DEALER AGAIN AT MY COSTS. NEXT THE TAIL LIGHTS AND BRAKE LIGHTS WENT OUT. EACH TIME IT WAS THE WIRING IN THE FUSE BOX UNDER THE HOOD. ALL REPAIRED AT MY EXPENSE. THE DEALER ACTED LIKE THEY HAD NO IDEA OF THE MULTITUDE OF ELECTRICAL PROBLEMS WITH THE AVEO BUT I THINK THEY'VE KNOWN, JUST READ SOME OF THE BLOGS-THIS IS A VERY COMMON PROBLEM. IT'S FRIGHTENING TO DRIVE THIS CAR JUST WAITING FOR A FIRE. FROM MAY 2013 TO PRESENT I CONTINUE TO HAVE THESE PROBLEMS. THE DAYTIME LIGHTS AND NOW THE CLOCK AGAIN GOING OUT. THE WHOLE FUSE BOX NEEDS REPLACED AS FAR AS I'M CONCERNED BUT THE DEALERSHIP KEEPS GIVING ME THE RUNAROUND--- NO MORE CHEVYS OR GM FOR ME. *TR

WHILE I AM DRIVING I OFTEN SMELL BURNING PLASTIC I COULD NOT TELL WHERE IT WAS COMING FROM. I CALLED GM AND THE REPRESENTATIVE TOLD ME THAT IT WAS COMING FROM MY DASH BEHIND MY STEERING WHEEL. I ALSO HAVE NOTICED THAT AFTER I HAVE DRIVEN ANYWHERE MY KEY, AFTER I HAVE TAKEN IT OUT OF THE IGNITION, IS REALLY HOT. THE LONGER I DRIVE THE HOTTER MY KEY BECOMES. WHEN I CALLED GM ABOUT THIS PROBLEM THE REPRESENTATIVE TOLD ME THAT SHE CAN NOT TELL MY WHY MY KEY GOT HOT. WHEN I ASKED HER ABOUT THE RECALL ON MY CAR THAT I HAD SEEN ON THE NEWS SHE TOLD ME THAT IT IS NOT AN OFFICIAL RECALL AND SHE CAN NOT DO ANYTHING ABOUT IT. THEY ALSO INFORMED ME THAT I CAN TAKE IT INTO A DEALERSHIP TO GET IT LOOKED AT BUT IT WOULD HAVE TO BE OUT OF POCKET. I HAVE TALKED TO GM MULTIPLE TIMES AND THEY HAVE TOLD ME ONLY THAT THE RECALL WOULD BE VIN SPECIFIC, I DON'T UNDERSTAND HOW IT IS VIN SPECIFIC IF I AM TELLING THEM THAT MY CAR IS NOT RIGHT. I REALLY WOULD JUST LIKE MY CAR LOOKED AT FOR THE PARTS THAT ARE SUPPOSED TO BE RECALLED BEFORE SOMETHING BAD HAPPENS TO ME OR MY PASSENGERS. I ALSO BELIEVE THAT SINCE THIS IS A KNOWN ISSUE I SHOULD NOT HAVE TO TAKE IT TO A DEALERSHIP TO GET LOOKED AT AND PAY HUNDREDS OF DOLLARS OUT OF MY POCKET. *TR
