What 505 owners told NHTSA about the 2011 Chevrolet Impala Limited

SERVICE STABILITRAK LIGHT CAME ON AS I WAS DRIVING ON THE INTERSTATE. BEFORE I COULD PULL OVER AND CHECK ON IT, THE CAR CUT OFF NEARLY CAUSING AN ACCIDENT AS I WAS ATTEMPTING TO CHANGE LANES AND COULD NO LONGER STEER THE CAR AT ALL. UPON ATTEMPTING TO START AGAIN, AS I WAS ON THE SIDE OF THE INTERSTATE AND NOT AS SAFELY OFF THE ROAD AS I NEEDED TO BE, IT TURNED ON AND OFF AGAIN, THIS TIME WITH THE CHECK ENGINE LIGHT ON. *TR

CHECK ENGINE - THEN POWER REDUCTION - DOWN TO ABOUT 20 MILES PER HOUR - JERKING ALL OVER THE PLACE - THEN STABLETECK LIGHT COMES ON... EXTREMELY DANGEROUS. LOCAL DEALERSHIP SAYS THIS HAPPENS FREQUENTLY - AND THEY DON'T REALLY KNOW WHATS GOING ON... GM FIX IT PLEASE... I DON'T HAVE 80,000 AND NOW A BUSTED VEHICLE - WON'T BUY ANOTHER GM PRODUCT EVER... OH YEAH - RETIRED FROM GM FAMILY

MY CAR HAS WARN OUT TWO SETS OF TIRES ON THE REAR . THE STILL IS SHOWING . I HAVE ALWAYS KNOWN THE FRONT TIRES TO WARE OUT TWICE AS FAST AS THE REAR. HOWEVER, IT IS NOT HAPPENING WITH THIS IMPALA. FOR SOME REASON THE STEEL IN THE TIRES ARE ALWAYS SHOWING CLOSE TO THE MIDDLE OF THE TIRE. I DON'T DRIVE MUCH SO THIS IS A BIG PROBLEM FOR ME. WHEN IT HAPPENED THE FIRST TIME WITH THE TIRES THAT CAME ON THE CAR, I BOUGHT A NEW SET AND HAD THE CAR ALIGNED. IT HAS DONE IT AGAIN SO I BELIEVE THERE IS A DEFECT IN THE CAR.

TL* THE CONTACT OWNS A 2011 CHEVROLET IMPALA. THE CONTACT STATED THAT THE WHEELS HAD SEIZED IN THE FRONT AND THE REAR WHEN, THE VEHICLE WAS IN MOTION. THE CONTACT HAD REPLACED ALL FOUR TIRES BUT THE FAILURE CONTINUED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE FRONT AND REAR ALIGNMENT NEEDED TO BE PERFORMED. IN ADDITION, THE ACCELERATOR PEDAL FAILED TO FUNCTION PROPERLY AND THE DEALER REPLACED THE PART. THE CONTACT WAS UNABLE TO DETERMINE WHEN THE VEHICLE WOULD BE REPAIRED WHICH WAS UNREASONABLE FOR THE CONTACT. THE FAILURE MILEAGE WAS NOT AVAILABLE.

WHEN STARTING FROM A STOP THE CAR JERKS AS IF THE TRANSMISSION IS TRYING TO CATCH UP AND IT FEELS LIKE YOU'VE BEEN HIT FROM BEHIND. IT'S AN ON AND OFF PROBLEM BUT IT HAPPENS IN THE RAIN AND IS DANGEROUS THE DEALER CHANGED THE TRANS OIL AND IT STILL DOES IT. NEXT THE CAR GOES INTO "REDUCED ENGINE POWER" AND "SERVICE STABILITRAK" WHILE DRIVING AND WILL NOT LET ME FINISH MY HIGHWAY DRIVE SAFELY, NO ONE AT THE DEALER CAN HELP WITH THIS EXCEPT TO SAY IT WILL CAST A LOT OF MONEY TO FIX. HEADLIGHTS CONSTANTLY BURN OUT AND I BOUGHT EXPENSIVE LIGHTS LAST TIME AND ONE IS ALREADY BURNT OUT. I HAVE ONLY 1 PAYMENT LEFT AND THE CAR IS READY FOR THE JUNKYARD, YOU WOULD THINK AFTER $28000.00 IT WOULD LAST A LITTLE LONGER. WHAT HAPPENED TO GM??

TRANSMISSION REPLACED DUE TO TORQUE CONVERTER FAILURE. 77000 MILES ON MY 2011 IMPALA. THIS VEHICLE IS NOT DRIVEN HARD. DRIVING AT ABOUT 40 MPH- THE VEHICLE SLIPPED OUT OF GEAR. VERY SCARY FOR THIS TO HAPPEN. TRAFFIC WAS VERY LIGHT. I WAS FEARFUL BECAUSE THE STREET I WAS ON WAS ONLY ONE LANE IN EACH DIRECTION, AND NOT MUCH OF A SHOULDER. I FELT VERY LUCKY I WAS NOT ON THE FREEWAY. THIS I BELIEVE COULD HAVE BEEN VERY DANGEROUS. I WAS ABLE TO DRIVE THE CAR AT A VERY SLOW SPEED TO A DEALERSHIP THAT WAS LESS THAN A MILE AWAY. SAD PART I WAS OVER 300 MILES FROM HOME. TORQUE CONVERTER FAILURE CAUSED HEAVY METAL DEBRIS IN THE TRANSMISSION LEAVING ME WITH A BILL TOTALING $3368.52. (PLUS OTHER EXPENSES DUE TO MY DISTANCE FROM HOME.)

THE CAR SEEMED TO BE RUNNING FINE I WAS ALMOST HOME. BUT IT SCARED ME SINCE ALL THOSE LIGHTS WERE FLASHING. ESPECIALLY THE ENGINE POWER REDUCING. READING ALL THESE STORIES I FEEL LUCKY THAT MY CAR DID NOT STOP ON ME. I REMEMBERED ID RECEIVED A LETTER THAT WAS NOT A RECALL BUT MENTIONED TO TAKE IN IF YOU HAD ANY ISSUES WITH THIS AND SHOULD BE COVERED OR REFUNDED IF FIXED IN THE PAST. I FOUND IT CALLED GM AND HAVE AN APPT IN 2 WEEKS WHICH WORRIES ME HOPE NOTHING HAPPENS BETWEEN THEN. THE BAD AND GOOD THING IS THAT NOW ALL THE LIGHTS HAVE COME OFF. HOPING THEY ARE STILL ABLE TO FIX IT AND I AM NOT HAVING TO PAY ANYTHING FOR IT. I FEEL LIKE THIS IS VERY DANGEROUS AND SHOULD BE A RECALL.

RELAY SWITCH ON DRIVER SIDE FOR AIR CONDITIONER CLICKS FOR SEVERAL MINUTES AND BLOWS HOT AIR. THE PASSENGER SIDE CURRENTLY BLOWS COLD BUT NOW THE CLICKING HAS BEEN HAPPENING THERE ALSO. I HAD A TOTAL STRANGER HEAR THE NOISE WHILE I WAS PUMPING GAS WHO SAID HIS IMPALA DID THE SAME THING. THIS IS OBVIOUSLY A COMMON DEFECT IN CHEVROLET IMPALAS THAT SHOULD BE TAKEN CARE OF. THIS HAPPENS EVERYWHERE ALL THE TIME MOVING AND PARKED

"TAKATA RECALL" ? CHECK AIRBAG LIGHT IS CONTINUOUSLY ON. DEALER STATES IT IS NOT RELATED TO RECALL AND NO RISK. THEY WILL REPAIR FOR A RIDICULOUS CHARGE. IF THERE IS NO RISK, I WILL NOT CONCERN MYSELF. THE LIGHT CAME ON WHILE ON A ROAD TRIP. IT IS UNKNOWN WHAT PART IS AT FAULT OR IF CONNECTED TO TAKATA ISSUES. IT HAS BEEN OVER 6 MONTHS.

"SERVICE AIR BAG" WARNING COMES ON INTERMITTENTLY: WHEN STARTING UP AND WHILE DRIVING. THIS IS VERY UNSAFE AND NEEDS TO BE RESOLVED AS SOON AS POSSIBLE. I HAVE BEEN RESEARCHING THIS AND HAVE FOUND MANY TO HAVE THE SAME PROBLEM.

FRONT BRAKE CALIPERS BINDING ON MY 2011 CHEVY IMPALA LT. NEW ROTORS AND CERAMIC PADS INSTALLED 2,000 MILES AGO AND NOW WARPED AGAIN. I HAVE $275.00 INVESTED AND WAS TOLD BY MY MECHANIC THAT THERE MAY BE A FACTORY RECALL ON THE CALIPERS. THERE IS 56,000 ON MY 2011 IMPALA NOW. THE VEHICLE WAS IN MOTION WHILE THIS WAS HAPPENING AND GOT WORSE AFTER A FEW HARD STOPS. ALSO CHECK STABILITY CONTROL SYSTEM WARNING CAME ON AND VEHICLE WENT INTO REDUCED POWER MODE WHICH IS VERY DANGEROUS IN TRAFFIC.

TAKATA RECALL THIS ISSUE IS THIS: I BOUGHT THE CAR IN DECEMBER 2015 FIRST MY ENGEN LIGHT COMES ON, THAN MY TRACTION CONTROLE LIGHT, THAN MY CAR TELLS ME TO SERVICE TRACTION CONTROLE, ENGEN POWER IS REDUCED, SERVICE STABIL TRACK, THE ENGEN CUTS I LOOSE POWER STEERING, AND I HAVE TO PULL OVER FOR 15 MIN WAITING FOR THE CAR TO REBOOT. I HAVE HAD THE CAR TO THE GM SHOP EVERY 2500-3000 MILES. THE SHOP REPLACED ALL THE FACTORY COVERED PARTS AND NOW WILL START GUESSING. THE FIRST FIX IS REPLACING SOME WIRES THAT ANOTHER SHOP REPLACED IN AN ATTEMPT TO FIX THIS SAME PROBLEM. NO ONE WILL FIX THIS DEATH TRAP. I WILL NOT DRIVE IT.

PULLING INTO THE DRIVEWAY AT ABOUT 10 MILES AN HOUR THE TRANSMISSION DIED, CAUSING THE CAR TO COME TO A DEAD STOP: THE TRANSMISSION HAS TO BE REPLACED NOW, HUSBAND HIT HIS HEAD OFF STEERING WHEEL, IF WE WERE ON A HIGHWAY DOING 60MILES PER HOUR WE COULD HAVE BEEN KILLED. THE CAR IS NOW AT TOM HESSER DEALERSHIP WHO SAID THEY WILL PAY HALF OF THE 4K TO FIX IT, THE CAR HAS 60400 SOME MILES ON IT, JUST TURNED 5 YRS OLD. I DO NOT THINK THIS CAR IS SAFE IF THE TRANSMISSION WILL JUST DIE AT ANY MOMENT WITHOUT WARNING.. IT DOES NOT HAVE OVER 100K MILES ON IT NOR DOES IT HAVE 61K MILES. THIS CAR MAKE AND MODEL HAS BEEN RECALLED FOR EVERYTHING BUT THE TRANY AND ENGINE SO FAR, THE CAR IS NOT SAFE PERIOD..THE DEALERSHIP WHO IS DOING REPAIRS IS NOT THE DEALERSHIP IT WAS PURCHASED FROM, , BUT IT IS A CHEVY DEALERSHIP. AND THEY ARE WILLING TO PAY HALF FOR REPAIRS, I THINK GMC SHOULD PAY THE ENTIRE COST FOR THE REPAIRS.

PASSENGER SIDE SEAT BELT SOUNDS OFF, AND FLASHES TO FASTEN SEAT BELT WHEN THERE IS NO PASSENGER IS IN THE CAR, AND THE AIR BAG PANEL FLICKS ON AND OFF CONSISTENTLY. WHEN I OPEN THE DRIVERS DOOR, THERE A TAPPING LIKE SOUND STARTS AND CONTINUES FOR FIVE TO SIX SECONDS AND THEN STOPS. WHEN I PUSH THE HEAT AND AIR LEVERS, IT STOPS. WHEN I TURN ON THE AIR OR HEAT, IT WILL MAKE THE TAPPING NOISE AND STOP AFTER A SHORT WHILE. THE NOISE SEEM TO BE GETTING LOUDER. WHEN THE CAR IS SITTING IN THE HEAT OR WHEN IN THE CAR JUST SITTING AND THE CAR NOT TURNED ON, THE SAME TAPPING NOISE WILL OCCUR. THE NOISE SOUNDS LIKE A WOOD PECKER SOUND. IT SOUND LIKE IT IS LOCATED IN THE COOLING SYSTEM AREA, CLOSE BY THE DASHBOARD AREA.
