2011 Chevrolet Impala

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

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 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

I PURCHASED A 2011 CHEVROLET IMPALA A YEAR AND HALF AGO FROM VICTORY CHEVROLET IN MOUNT HOLLY< N.C. AFTER THE FIRST WEEK OF OWNING THE CAR WHICH HAD ONLY 27000 MILES ON IT THE STABILTRAK LIGHT CAME ON, SINCE THEN IT HAS HAPPENED FOUR TIMES INCLUDING TODAY, TWO OF THESE TIMES I CAME CLOSE TO HAVING A WRECK. I FOUND ON THE WEB THAT THIS IS HAPPENING TO THE IMPALAS. I WROTE GM TO ASK IF SOMEONE WOULD HAVE TO BE KILLED TO RECALL THESE AND BE FIXED. IF YOU LOOK AT THIS YOU WILL SEE THEY DID RECALL THE POLICE CARS BUT NOT THE PERSONAL VEHICLES. I DON'T KNOW IF YOU CAN HELP BUT I WILL CONTACT ALL THE NEWS MEDIA TILL SOMEONE WILL LISTEN. AGAIN I HAVE TO TAKE MY CAR IN FOR REPAIRS FOR THE SAME REASON. THANK YOU! IF CANADA IS SUING GM FOR THIS REASON THEN WHY IS SOMETHING DON'T DONE HERE? *TR
