COMING HOME FROM WORK, DASH LIGHTS GOT BRIGHTER, AIRBAG LIGHT STAYED ON, CAR TRIED TO STALL AROUND A CORNER WHEN BRAKES WERE PRESSED. TOOK IN FOR SERVICE, HAD ALTERNATOR AND BATTERY REPLACED, ALSO SERPENTINE BELT. THIS WAS 4 MONTHS AGO. PROBLEM WAS NOT FIXED, JUST MADE IT LESS SEVERE. SINCE THAT TIME, WHEN YOU HIT THE BRAKES THE HEADLIGHTS DIM. THE DASH CLOCK COMES ON AND OFF RANDOMLY, THE AIRBAG LIGHT IS ON ALL THE TIME. WHEN IT IS COLD (THE CAR, NOT THE WEATHER), THE TRANSMISSION HAS A HARD TIME SHIFTING. AS OF THIS MORNING IT WILL NOT START. AM GOING TO HAVE IT LOOKED AT TOMORROW MORNING, BUT DO NOT HAVE HIGH HOPES. BOUGHT CAR IN 2006 WITH 8,000 MILES ON IT, HAVE HAD SHIFT LOCK ASSEMBLY REPLACED, WHEEL BEARINGS, BATTERY, ALTERNATOR, SERPENTINE BELT. PROBABLY OTHER THINGS I CANNOT THINK OF RIGHT NOW. THE ELECTRICAL PROBLEM WORRIES ME THOUGH. *TR

2005 AVEO (BOUGHT NEW) WITH TIMING BELT FAILURE DESTROYING ENGINE. HAD THIS HAPPENED ON THE INTERSTATE AT 70 MILES AN HOUR IT COULD HAVE BEEN FATAL. FROM MY RESEARCH GMC HAS KNOWN ABOUT THIS ISSUE SINCE AT LEAST 2006 AND YET HAVE NOT ASSISTED CONSUMERS TO CORRECT THIS NOR RECALLED THEIR CAR. I HAVE READ REPORTS ON ALMOST ALL YEARS OF AVEO HAVING THIS PROBLEM WELL BEFORE THE 60000 RECOMMENDED TIMING BELT REPLACEMENT. TWO DIFFERENT MECHANICS CONFIRMED TIMING BELT FAILURE. ALL I GET FROM GMC IS THE RUN AROUND. UPSET OVER MONEY BUT MORE CONCERNED ABOUT THESE CARS BEING ON THE HIGHWAYS AND CREATING SOME HORRIBLE ACCIDENT WHEN THE ENGINE SUDDENLY STOPS WORKING AND CONTROLLING THE CAR IS DIFFICULT OR IMPOSSIBLE. PLANNING TO GET RID OF MINE, CAN'T AFFORD THE THOUSANDS OF DOLLARS TO FIX NOR DO I TRUST THIS CAR. *TR

I WAS TRAVELING NORTH UNDER AN OVERPASS WHEN MY LIGHT TURNED GREEN AND A CAR COMING OFF THE HWY HEADING WEST RAN THE STOP LIGHT. I HIT THE BRAKES WHEN I SAW HER BUT IT WAS TOO LATE AND SHE WAS GOING TOO FAST. THE FRONT BUMPER ON THE 2005 CHEVROLET AVEO I WAS DRIVING HIT HER CAR ON THE DRIVERS SIDE AFT QUARTER PANEL. THE IMPACT SPUN HER CAR ALL THE WAY AROUND AND I JUST ROLLED TO A STOP. I GOT OUT TO GO TALK TO HER AND SHE DROVE OFF. I GOT BACK IN MY CAR AND FOLLOWED HER. WHEN I CAUGHT UP TO HER, SHE WAS A NERVOUS WRECK. I TALKED HER INTO FOLLOWING ME ACROSS THE STREET TO A CIRCLE K GAS STATION AND WAITED FOR POLICE. SHE WAS DRIVING A 2005, I THINK, LEXUS 330, AGAIN I THINK. THE BAD THING WAS NEITHER ONE OF OUR CARS AIRBAGS DEPLOYED. HER CAR MIGHT BE CORRECT BUT ALL MY DAMAGE WAS STRAIGHT IN THE FRONT ON THE BUMPER AND THE HOOD HAS SOME MINOR DAMAGE BUT THE FRONT BUMPER IS TRASHED. I WAS WEARING MY SEATBELT BUT I DID INJURE MY BACK AND MY STOMACH AREA. I HAVE NOT BEEN TO THE DOCTOR YET AS I AM WAITING TO MAKE SURE I'M NOT JUST SORE FROM THE IMPACT. *TR
