THE LOCKING MECHANISM ON MY 2005 CHEVROLET AVEO HAS BEEN GETTING STUCK. IT DOES NOT OPEN MANUALLY, IT WILL NOT UNLOCK WITH THE KEY INSERTED ON THE DOOR, NOR WILL IT UNLOCK WHEN I AM INSIDE THE VEHICLE. THE ONLY WAY TO OPEN MY DOOR IS WITH THE REMOTE.

THE LOCKING MECHANISM ON MY 2005 CHEVROLET AVEO HAS BEEN GETTING STUCK. IT DOES NOT OPEN MANUALLY, IT WILL NOT UNLOCK WITH THE KEY INSERTED ON THE DOOR, NOR WILL IT UNLOCK WHEN I AM INSIDE THE VEHICLE. THE ONLY WAY TO OPEN MY DOOR IS WITH THE REMOTE. I FEAR THAT IN THE EVENT OF AN EMERGENCY I WILL NOT BE ABLE TO EXIT MY VEHICLE IN TIME. THERE IS ALSO THE FEAR THAT I MAY BECOME STRANDED BECAUSE THE BATTERIES IN THE REMOTE HAS DIED AND I WILL BE UNABLE TO OPEN THE DOOR EVEN THOUGH I HAVE MY KEYS. *TR

WE WERE DRIVING ALONG IN THE DEAD OF WINTER AND NOTICED THERE WAS NO HEAT. WE HOOKED IT UP TO A CODE READER AND IT CAME UP P0128 A THERMOSTAT HOUSING FAULT. BROUGHT IT IN TO GET CHECKED AND IT IS THE THERMOSTAT HOUSING AND THE SERVICE CENTER EMPLOYEES ALL KNEW THIS A KNOWN FAILURE ON THIS VEHICLE. THE OUT OF POCKET COST 160.00 FOR PART ONLY FROM CHEVY NOT INCLUDING LABOR. THE NEW ONE IS METAL NOT PLASTIC LIKE THE ONE THAT ROLLED OUT OF THE FACTORY, SO THIS MUST BE A CONSUMER PAID RECALL. WHICH SHOULD BE AGAINST THE LAW. IF YOU MAKE A FAULTY PART THAT FAILS YOU SHOULD PAY FOR IT. JUST ASK TOYOTA, THEY ARE. *TR

THE CLOCK ON MY 2005 CHEVY AVEO DOES NOT WORK CONTINUOUSLY. SOMETIMES THE DISPLAY WORKS AND SOMETIMES IT DOES NOT. AS FOR SAFETY ISSUES, THE PLASTIC THERMOSTAT HOUSING BROKE WHILE DRIVING DOWN THE ROAD LAST WEEK. AFTER PRICING REPLACEMENT PLASTIC PARTS, WE OPTED TO PURCHASE THE METAL ONE, WHICH CAN ONLY BE PURCHASED FROM THE DEALER AND WHICH IS MORE THAN TWICE THE PRICE OF THE PLASTIC ONES. WE STILL HAD A LEAK, SO WE CALLED A LOCAL NAPA STORE AND PURCHASED A GASKET FOR UNDER $2. AFTER REMOVING AND THEN ATTEMPTING TO REPLACE THE PART AGAIN, ONE OF THE BOLT HOLES BROKE OFF. ISN'T THE METAL SUPPOSED TO BE MORE DURABLE? ALL THIS HAS HAPPENED IN LESS THAN A WEEK AND THE DEALER REFUSES TO STAND BEHIND THE PART. NOT ONLY WAS THE PLASTIC PIECE SHODDY, SO IS THE METAL ONE AND SO IS CHEVROLET'S CUSTOMER SERVICE. *TR

WHILE TRAVELING TO A DOCTOR APPOINTMENT AT APPROXIMATELY 2:30 PM ON 11/18/09, I HYDROPLANED ON THE WET INTERSTATE I 40 EAST, NEAR EXIT 37, SLID SIDEWAYS AT A 90' ANGLE TO OUTSIDE LANE OF I 40 EAST, ATTEMPTED TO COUNTERSTEER INTO THE SLIDE, WHICH CAUSED MY VEHICLE TO SPIN 360' AND STRIKE THE CONCRETE LANE DIVIDER HEAD ON AT 40 OR 45 MPH. THE VEHICLES AIR BAGS DID NOT DEPLOY, AND I PROBABLY SUSTAINED A GREATER CHEST CONTUSION TO MY STERNUM DUE TO SEAT BELT RESTRAINT IMPACT TO MY CHEST. THIS HAS ALSO CAUSED AN INCREASE TO BACK PAIN DUE TO A PRIOR PROBLEM OF 3 FUSED VERTEBRAE IN MY UPPER SPINE AND PROBABLY A FRACTURED STERNUM, BUT X-RAYS ARE NOT CONCLUSIVE. I CAN NOT HELP BUT THINK HAD THE AIRBAGS DEPLOYED I WOULD NOT HAVE SUSTAINED SUCH A SEVERE BLOW TO MY CHEST AND WOULD NOT HAVE BEEN INJURED NEARLY AS BAD AS I HAVE BEEN. I BELIEVE THE AIR BAG SYSTEM MALFUNCTIONED AS THE CAR WAS A TOTAL LOSS, AND THE IMPACT KNOCKED ME UNCONSCIOUS FOR ABOUT 15 SECONDS. I REMEMBER THE BACK WHEELS OF THE VEHICLE FLYING UP INTO THE AIR, AND THE REAR END BOUNCING BACK TO THE GROUND. *TR

ON SUNDAY EVENING I ATTEMPTED TO PUT MY 2005 CHEVY AVEO INTO DRIVE AFTER PUTTING MY KEY IN THE IGNITION AND STARTING THE VEHICLE BUT THE SHIFTER WAS STUCK IN PARK. THE AVEO HAS A FEATURE CALLED THE "SHIFT LOCK RELEASE" WHICH IS A HOLE ON THE SHIFTER CONSOLE YOU CAN PUT A SCREWDRIVER OR OTHER TOOL INTO TO RELEASE THE SHIFTER INTO DRIVE IN THESE SITUATIONS. I WAS ABLE TO PUT THE CAR IN DRIVE AND MAKE IT HOME SAFELY AFTER USING THE SHIFT LOCK RELEASE BUT WHEN I GOT HOME I REALIZED MY KEY WAS STUCK IN THE IGNITION. MY CAR SAT UNLOCKED OVERNIGHT BECAUSE I COULD NOT GET THE KEY OUT. ON MONDAY I CALLED MY LOCAL GM DEALERSHIP IN SALEM, OH AND THEY STATED THEY WOULD NOT BE ABLE TO TAKE A LOOK AT MY CAR UNTIL TUESDAY. I SPENT THE ENTIRE DAY RESEARCHING ONLINE AND FOUND MANY CUSTOMERS WHO HAVE EXPERIENCED THIS SAME ISSUE WITH THE AVEO. LATER ON IN THE EVENING I REALIZED MY BRAKE LIGHTS WEREN'T WORKING BUT THERE WAS NOT A BLOWN FUSE OR SWITCH. I TESTED BOTH OF THE BRAKE LIGHTS AND THEY WERE STILL GOOD. ON TUESDAY I TOOK MY CAR TO THE DEALERSHIP AND IT COST ME $80 FOR THE MECHANIC TO TELL ME THE SHIFTER IS BAD, WHICH I ALREADY KNEW. THEY ALSO STATED IT WOULD BE $300 TO REPAIR THE SHIFTER. I STRONGLY BELIEVE THE FAILURE OF THE BRAKE LIGHTS, THE SHIFTER AND THE IGNITION ARE TIED TOGETHER AND SHOULD BE REPLACED BY GM AT NO COST TO ME. MY VEHICLE IS SITTING UNATTENDED WITH THE KEY IN IT, WHICH RUNS THE RISK OF IT BEING STOLEN. NOT TO MENTION WHEN I AM DRIVING I HAVE NO BRAKE LIGHTS TO ALERT THE OTHER DRIVERS I AM SLOWING DOWN OR STOPPING WHICH COULD CAUSE AN ACCIDENT. EACH TIME I ATTEMPT TO PUT THE CAR IN DRIVE I HAVE TO INSERT SOMETHING INTO THE SHIFT LOCK RELEASE TO SHIFT THE CAR AND THIS HAS BEEN GOING ON SINCE SUNDAY. *TR

TOOK TO A MECHANIC AND HE INITIALLY REPLACED THE DIMMER SWITCH BECAUSE IT WAS BURNT. HOWEVER, THAT DID NOT SOLVE THE PROBLEM. AFTER FURTHER INVESTIGATION, HE SAYS THAT THE PURPLE WIRE LEADING TO THE SPLICE PACK HAS BURNED. IN TRYING TO OBTAIN THE PART, CHEVROLET WILL ONLY SELL THE ENTIRE SPLICE PACK; TO THE TUNE OF $5,100!!! AFTER RESEARCHING ONLINE, I HAVE FOUND HUNDREDS OF PEOPLE WITH THE EXACT SAME PROBLEM. NO THERE HASN'T BEEN A FIRE YET! *TR
