WHEN MY IMPALA WAS 4 YEARS OLD AND 42000 MILES(APRIL OR MAY OF 2013), BOTH REAR DOOR LOCKS REFUSED TO LOCK OR UNLOCK. I CONTACTED MY DEALER AND HE STATED THAT IT WAS OUT OF WARRANTY. I THEN CONTACTED GMS CUSTOMER SERVICE WHICH REITERATED THE SAME THING. AFTER INVESTIGATING ONLINE, THERE ARE QUITE A FEW BLOGS WITH CUSTOMERS WHO HAVE THE SAME PROBLEM. TO REPLACE THESE LOCKS COSTS APPROXIMATELY $800. I CONTACTED YOUR ORGANIZATION THIS MORNING AND THEY TOLD ME TO CONTACT CHEVROLET AT 1-800-222-1020. WHEN I CONTACTED THEM, I WAS INFORMED THAT THE SERIAL NUMBER DID NOT FALL UNDER ANY RECALLS. HOWEVER, CHEVROLET DOES HAVE A DOOR LOCK RECALL. *TR

I WAS DRIVING MY CAR AND IT BEGAN TO SHAKE AND LOSE POWER AND WOULD NOT ACCELERATE. THE CHECK ENGINE LIGHT CAME ON WITH MESSAGES REDUCED ENGINE POWER, SERVICE STABILTRAK. THIS HAS BEEN HAPPENING QUITE A BIT WITH THIS CAR. I HAVE BEEN RESEARCHING ONLINE AND HAVE NOTICED THAT NUMEROUS COMPLAINTS HAVE BEEN FILED GOING BACK YEARS. GM SHOULD TAKE CARE OF THIS PROBLEM AS IT IS HAPPENING WITH NUMEROUS VEHICLES. I DRIVE ON THE INTERSTATE EVERY DAY AND IF THIS HAPPENS THERE I HOPE IT DOESN'T CAUSE AN ACCIDENT. *TR

THE THREE REAR SEAT HEADREST ARE WAY TOO LARGE AND HIGH AND BLOCK THE DRIVERS VIEW OUT OF THE REAR WINDOW. EACH ONE OF THE THREE HEADREST BLOCK PART OF THE VIEW OUT OF THE REAR WINDOW. THIS IS A VERY DANGEROUS SITUATION THAT DRIVERS OF THIS CAR ARE BEING FORCED TO DEAL WITH. THERE SHOULD BE ABSOLUTELY NOTHING INTERFERING WITH THE VIEW OUT OF THE REAR WINDOW FROM THE DRIVERS SEAT. THE REAR SEAT HEADREST ARE OBVIOUSLY OBSTRUCTING THE DRIVERS VIEW OUT OF THE REAR WINDOW. THIS IS AN OBVIOUS SAFETY HAZARD. IT IS JUST A MATTER OF TIME BEFORE SOMEONE BACKS INTO SOMETHING OR SOMEONE OR CHANGES LANES CAUSING A CRASH ON A HIGHWAY DESTROYING PROPERTY, INJURING OR KILLING SOMEONE. THEN THERE WILL BE A HUGE CIVIL SUIT AND YOU CAN BET THE DRIVER OF THE CAR WILL PREVAIL ESPECIALLY AFTER THIS SAFETY HAZARD HAS BEEN REPORTED TO GM, NHTSA, THE BBB AND OTHERS AND NOTHING WAS DONE TO MANDATE A RECALL TO HAVE THESE HEADREST REMOVED.

AS I WAS DRIVING DOWN THE ROAD MY CAR LOST SPEED DROP FROM 35 MPH TO 20 MPH, THE CHECK ENGINE LIGHT CAME ON AND THE TRIANGLE WITH THE CAR AND SKID MARKS THEN IT KEPT FLASHING THE SERVICE STABILITRAK CONTROL, ENGINE POWER REDUCED, AND SERVICE TRACTION CONTROL AND IT STARTED TO JERK AND JUMP. I HAVE BEEN HAVING MAJOR ISSUES OUT OF THIS CAR FIRST IT WAS THE RIGHT HUB (EATING TIRES), THEN THE LEFT HUB (EATING MORE TIRES), THEN THE TRANSMISSION AND GEAR SHIFT COMPLETELY GONE (REPLACED EVERYTHING) NOW THIS PLUS THE FRONT TIRES ARE STILL GETTING ATE UP. THIS IS AN ONGOING PROBLEM WITH THIS CHEVY IMPALA. I AM SO READY TO GET A HONDA. AS I SEE THERE ARE OTHER OWNERS THAT ARE HAVING SIMILAR PROBLEMS. WHY ISN'T IT A RECALL ON THESE PROBLEMS? NOBODY LIKES TOO LOOSE THEIR MONEY FOR SOMETHING THAT SHOULD HAVE BEEN TAKEN CARE OF BY GM IN THE FIRST PLACE. WHAT WILL GM DO IF ALL CUSTOMERS PROTEST ABOUT THESE ISSUES THAT SHOULD BE RECALLED ON WHETHER ITS FOR THE PUBLIC, PRIVATE, OR GOVERNMENT SECTOR? *TR

I PURCHASED A 2011 CHEVROLET 2011 IMPALA LT CAR RECENTLY. I FIND THAT THE HEIGHTS OF THE THREE BACK-SEAT HEAD RESTS ARE EXTREMELY HAZARDOUS FOR A DRIVER OF THIS CAR. EACH HEAD REST IS FIVE INCHES TOO HIGH TO SEE OUT THE BACK WINDOW. I HAD NOT HEARD BEFORE HAND THAT THE 2011 IMPALA WAS WELL KNOWN FOR THIS PROBLEM UNTIL AFTER I HAD PURCHASED THE CAR. RECENTLY, BECAUSE OF MY LIMITED VISIBILITY PAST THE LEFT BACK-SEAT WINDOW HEAD RESTS, IN BACKING MY CAR, I BUMPED A PARKED CAR. MY LEFT REAR FENDER STRUCK THE LICENSE PLATE HOLDER OF THAT CAR. THE COST OF THIS FENDER REPAIR WAS $983.00. I FEAR THAT MY DRIVING THIS CAR WITHOUT CHANGES MADE IN THE CONSTRUCTION OF THESE HEAD RESTS IS LEADING TO ANOTHER MORE SERIOUS ACCIDENT WAITING. TO HAPPEN. I WILL APPRECIATE YOUR ATTENTION INTO THIS MATTER. THANK YOU.

MY DAUGHTER WAS DRIVING 45 MPH IN THE RAIN, THE CAR LIGHTED UP AND READ THE STABILITRAK WAS HAVING A PROBLEM AND REDUCED POWER...CAR SLOWED SUDDENLY. SHE WAS DRIVING AT NIGHT. SHE PULLED OVER, SHUT OFF THE CAR, RESTARTED IT. THIS LAST WEEK, THIS IS NOW A MULTIPLE TIME PER DAY OCCURRENCE. LAST SUMMER AFTER THE FIRST INCIDENT, SHE TOOK THE CAR TO THE CHEVY DEALER IN WATERVILLE, WHO HOOKED IT UP TO THE COMPUTER WHICH DID NOT SHOW ANY CODE. HE TOLD HER TO CONTINUE DRIVING IT AND IT PROBABLY GOT WET. SHE TOOK IT AGAIN TODAY TO ANOTHER GARAGE IN WATERVILLE, WHO HOOKED IT UP TO THE COMPUTER, AND IT DID NOT SAY ANYTHING WAS WRONG. SHE IS EXPERIENCING LOSS OF POWER TO THE CAR MULTIPLE TIMES A DAY WITH MULTIPLE WARNINGS ABOUT THE STABILITRAK. THIS IS A DANGEROUS SITUATION. *TR

I WAS DRIVING ON I70 GOING 70 MPH AND OUT OF NOWHERE MY ENGINE LIGHT COMES ON AND 3 MESSAGES START APPEARING ON THE DASH. 1) SERVICE STABILTRAC, 2) SERVICE TRACTION CONTROL, 3( ENGINE POWER REDUCING. MY CAR A 2011 CHEVY IMPALA SLOWS DOWN TO ABOUT 50. I GET IT GOING BACK TO 60 BUT NOT VERY EASILY. I KEEP GOING AND MERGE ONTO 465 (INDIANAPOLIS INDIANA AREA). I COME INTO SLOWER TRAFFIC WHERE I NEED TO STOP. I APPLY MY BREAKS AND THE PEDAL WILL NOT ENGAGE. ALMOST HIT A CAR. ALSO WHEN I SLOWED DOWN THE CAR STARTED SHAKING BAD. I CONTINUE A LITTLE FARTHER IN SLOW TRAFFIC AND HAD TO STOP AGAIN, SAME THING WITH THE BREAKS. SO I PULLED OVER AND SHUT OFF MY CAR ON THE SIDE OF I465. MY DAUGHTER HAD LOOKED UP THE ERROR MESSAGES ON THE INTERNET AND THERE SEEM TO BE A LOT ON THERE WITH THE SAME PROBLEM. THEY ALL SAID THE SAME THING, AFTER SHUTTING THE CAR OFF AND RESTARTING IT IT WAS FINE. I MADE IT HOME AND EVERYTHING SEEMED FINE FOR A COUPLE OF WEEKS AND IT HAPPENED A FEW MORE TIMES SO FAR. ONCE AT A STOP SIGN AND THE SAME DAY AS I WAS BACKING OUT OF PARKING SPACE AT WORK. ONCE AGAIN THAT SAME WEEK I WAS DRIVING IN TOWN AND TOOK OFF FROM A RED LIGHT AND IT HAPPENED AGAIN. FROM A COMPLETE STOP THE CAR STARTED SHAKING AND THE ERROR MESSAGES AND ENGINE LIGHT COME ON AND IT WOULD NOT ACCELERATE. I WOULD HAVE THOUGHT NOTHING ABOUT IT EXCEPT TO GET IT FIXED, BUT AFTER READING SO MUCH ON THE INTERNET ABOUT THE SAME PROBLEM THERE HAS TO BE AN ISSUE AND NEEDS TO BE RECALLED. GM NEEDS TO OWN UP TO THIS PROBLEM BEFORE PEOPLE GET INJURED OR WORSE DIE FROM THIS ISSUE. *TR

THE CHECK ENGINE LIGHT CAME ON (AND HAD GONE OUT) PREVIOUSLY. DASH SAID "SERVICE STABILITRAC, ENGINE POWER REDUCED" AND A MECHANIC SAID IT WAS A "SENSOR IN THE GAS PEDAL" AND THAT IF IT KEPT HAPPENING WE SHOULD REPLACE IT. I DIDN'T FULLY REALIZE THAT THIS MEANT THAT THE THROTTLE WOULD DISABLE ITSELF WHILE I WAS DRIVING IN MORNING RUSH HOUR TRAFFIC ON THE HIGHWAY IN THE LEFT HAND LANE GOING UP A HILL DOING 60 MPH. THERE WAS TRAFFIC BEHIND ME AND IN OTHER LANE SO I HAD TO PULL INTO THE CENTER SHOULDER OVERTOP OF 5 INCHES OF SNOW AND ICE. IT WAS A STRUGGLE NOT TO HIT THE GUARDRAIL. THERE WAS BARELY ENOUGH ROOM. I JUST MADE IT OVER THE YELLOW LINE. IT WAS 20 DEGREES AND THEN HAD TO WAIT AN HOUR FOR A TOW TRUCK. THE CAR DID START AND DRIVE AT THE GARAGE. THIS MECHANIC REPLACED THE ACCELERATION PEDAL ASSEMBLY. THE ERROR WAS CODE P2122. HE ALSO STATED THAT HE COULD SMELL BURNING WIRES. I HAD SMELLED IT BUT DIDN'T REALIZE WHAT IT WAS. *TR

SERVICE AIRBAG LIGHT COMES ON WHEN START. WILL RESET TILL RESTART. DEALER QUOTE WAS 550 FOR PART 200 LABOR. JUST NOW 3 YEARS OLD WITH ALL OTHER COMPLAINTS OBVIOUSLY A DEFECTIVE SAFETY RELATED PART. CHEVY AND GM APPEAR TO BE IGNORING THIS ISSUE AND MAKING A GOOD PROFIT ON DEFECTIVE PARTS. COME ON GM HOW ABOUT BACKING UP YOUR PRODUCT. WE BAILED YOU OUT HOW ABOUT MAKING THINGS RIGHT WITH PEOPLE THAT ARE STILL BUYING YOUR CARS. THIS MAY BE MY 3RD AND LAST GM PRODUCT. *TR

I WAS DRIVING DOWN THE INTERSTATE WITH THE CRUISE CONTROL ON WHEN SUDDENLY MY CAR JERKED AND A MESSAGE SHOWING "ENGINE POWER REDUCED, SERVICE STABILITRAK" SHOWED UP. I NOTICED THE RPMS JERKING UP AND DOWN WITH A PRETTY DRAMATIC RANGE. WHEN I SLOWED DOWN MY CAR STARTED SHAKING. THE WORST PART IS THAT WHEN I SHUT MY CAR OFF THE PROBLEM STOPS. THIS HAS HAPPENED 4 OTHER TIMES. ONCE WHILE IDLING. ONCE WHILE SLOWING DOWN FROM 55 TO 35 AND ONCE WHILE DRIVING ABOUT 35 MPH. THERE SEEMS TO BE NO PATTERN AND IT IS INTERMITTENT. *TR

I STARTED MY CAR AFTER A COLD NIGHT AND IMMEDIATELY GOT A "SERVICE STABILITRAK", "ENGINE POWER REDUCED", AND "SERVICE TRANCE ION CONTROL" MESSAGES. THE CAR HAD AN EXTREMELY ROUGH IDLE AND THEN WOULD NOT ACCELERATE TO MORE THAN 25 MPH. I RETURNED HOME AND MADE AN APPOINTMENT AT THE DEALERSHIP. LATER, I WAS READY TO TAKE THE CAR INTO THE DEALER AND IT STARTED FINE WITH NO ERROR MESSAGES OR CHECK ENGINE LIGHT. I CALLED THE DEALER AND THEY SAID IT MUST HAVE BEEN A COMPUTER ERROR THAT FIXED ITSELF. WELL, IT'S A WEEK LATER NOW AND I AM HAVING THE ISSUES AGAIN EXCEPT RESTARTING THE ENGINE DOES NOT FIX IT ANYMORE. THIS IS A SERIOUS ISSUE AND NEEDS TO BE RESOLVED BY GM AND NOT COST THE MANY PEOPLE EXPERIENCING THIS ISSUE HUNDREDS OF DOLLARS TO FIX! *TR

WHILE DRIVING DOWN THE ROAD SERVICE TRACTION CONTROL REDUCE ENGINE POWER AND STABILITY CONTROL LIGHT CAME ON. CAR ENGINE LOST POWER AND I THOUGHT IT WAS GOING TO BLOW UP IT MADE THE WHOLE CAR SHAKE. YOU SHUT IT OFF FOR A FEW AND RESTART IT AND ITS LIKE NOTHING EVER HAPPENED. NOT TO HAPPY ABOUT THIS I HAVE NOT HAD THE CAR A YEAR. GUESS A PERSON NEEDS TO DIE FROM THIS MATTER BEFORE THERE IS A RECALL ON THIS WHAT A JOKE. AND THE WORST IS CHEVY WILL NOT COVER ANY OF THIS EVEN IF THE CAR IS UNDER A WARRANTY. *TR

WHILE DRIVING DOWN THE ROAD, THE CAR WILL VIOLENTLY JERK, AND THE DASHBOARD WILL FLASH, REDUCED ENGINE POWER. NOW CAR WON'T MOVE AT ALL. WE HAVE REPLACED THE GAS PEDAL TWICE! CHEVROLET NEEDS TO ADDRESS THIS ISSUE. I AM SEEING IT ALL OVER THE INTERNET. *TR

WHILE DRIVING AT 60 MPH, MESSAGES WERE FLASHING: SERVICE STABILITRAC SOON, REDUCED POWER TO ENGINE, CHECK TRACTION CONTROL. CAR DECELERATED TO 30 MPH ON THE HIGHWAY, HARD TO STEER. I PULLED OFF THE ROAD, TURNED IT OFF AND WAITED. SEVERAL MINUTES LATER IT RESTARTED AND I WAS ABLE TO DRIVE IT HOME. THE ENGINE LIGHT AND THE TRACTION CONTROL LIGHT STILL COME ON. IT SHIFTS HARD (AND IT'S AN AUTOMATIC TRANSMISSION). IN ADDITION, CRUISE CONTROL WILL NOT WORK DURING THIS CONDITION. *TR

THIS IS THE SECOND TIME THIS HAS HAPPENED. LESS THAN A YEAR AGO, WE RECEIVED A SERVICE STABILITRAC/SERVICE TRACTION CONTROL/ENGINE AT REDUCED POWER MESSAGE AND SPEED DROPPED FROM 40 MPH TO 5 MPH. WE BROUGHT IT TO THE CHEVROLET DEALER AND A TRACTION POSITION CONTROL SENSOR WAS REPLACED. TODAY, ON 11/24/13, WE WERE DRIVING 15 MPH IN A PARKING LOT AND RECEIVED THE SAME MESSAGE RESULTING IN THE SAME PROBLEM. THIS IS A SAFETY ISSUE DUE TO THE FACT THAT THE VEHICLE ESSENTIALLY STALLS OUT WITH LITTLE TO NO POWER AND NEARLY CAUSED A COLLISION AT AN INTERSECTION. WHEN WILL NHTSA FORCE GM TO RECALL AND FIX THIS ISSUE? THIS IS EXTREMELY DANGEROUS. *TR
