2011 Chevrolet Impala

I WAS DRIVING DOWN I-74 OUTSIDE PEORIA IL AND THE STABILITRAC POWER REDUCED POPPED UP ON THE DASH AND 3 SECONDS LATER IT STATED THE ANTI-THEFT ENGAGED AND SHUT MY CAR OFF. I ALMOST GOT REAR ENDED BY MULTIPLE CARS ON THE INTERSTATE. I WAS IN THE LEFT LANE AND BARELY MADE IT TO THE SIDE OF THE ROAD. I EMAILED GM AND THEY HAVE NOT GOTTEN BACK TO ME YET. I EMAILED THEM THE SAME DAY IT HAPPENED. *TR

THE SERVICE STABILITRAK, TRACTION CONTROL, AND REDUCED ENGINE POWER WARNINGS CAME ON AND THE CAR STARTED TO LOSE POWER GOING AROUND A CURVE. I TEMPORARILY LOST THE ABILITY TO ACCELERATE NEARLY CAUSING ME TO GET REAR ENDED BY A VEHICLE BEHIND ME. SINCE THE INCIDENT OCCURRED THE CAR HAS BEEN VERY SLUGGISH AND UNSAFE TO OPERATE. I AM PLANNING TO GET THIS SERVICED ASAP. AFTER READING MANY FORUM POSTS ONLINE REGARDING THIS SAFETY ISSUE, I BELIEVE A RECALL SHOULD BE ISSUED. I WAS SHOCKED TO SEE HOW RAMPANT OF A PROBLEM THIS AND THAT IT IS USUALLY CAUSED BY A FAULTY THROTTLE BODY THAT ISN'T COVERED IN THE 100K MILE POWERTRAIN WARRANTY. MYSELF AND MANY OTHERS FROM WHAT I HAVE READ BELIEVE THIS TO BE A VERY DANGEROUS MALFUNCTION. IF THIS WERE TO HAPPEN AT HIGH SPEEDS ON THE HIGHWAY SOMEONE COULD VERY EASILY BE KILLED IF THEIR CAR LOSES POWER DUE TO THIS. *TR

THE CAR STARTED JERKING WHILE DRIVING ON THE HIGHWAY MESSAGE PANEL SAID THAT THE STABILITRAC NEEDED SERVICE AND THAT ENGINE POWER WAS REDUCED AND THE TRACTION CONTROL NEEDED SERVICE. I HAD JUST BOUGHT THE CAR I TOOK IT BACK TO THE DEALERSHIP THEY SAID IT WAS SOMETHING SIMPLE AND FIXED IT. THE NEXT DAY IT HAPPENED AGAIN ONLY WORSE AND THE CAR WOULD NOT GO OVER 40 MPH. THE CAR IS JERKING AND I AM AFRAID TO EVEN DRIVE IT TO THE DEALERSHIP. THERE ARE MANY COMPLAINTS JUST LIKE THIS. THERE REALLY NEEDS GO BE SOMETHING DONE TO HELP WITH THIS PROBLEM. *JS

I WAS STOPPED AT A LIGHT AND THE FRONT END HESITATED THEN TOOK OFF NORMALLY. I GOT ON A HIGHWAY, DROVE 30 MILES AND AS I WAS DECELERATING MY CHECK ENGINE LIGHT CAME ON AND A MESSAGE TO SERVICE MY TRACTION CONTROL LIGHT APPEARED. I LOOKED UP THIS PROBLEM ON THE INTERNET AND SEE THAT IT IS A COMMON PROBLEM ACROSS MANY MODELS AND NUMEROUS MODEL YEARS. IT WAS SUGGESTED TO LOG THE COMPLAINT . *TR

I WAS ON THE HIGHWAY DOING 60MPH AND MY DASH SHOWED A MESSAGE ENGINE POWER REDUCED, SERVICE TRACTION STATION, SERVICE STABILITRAK. THE STEERING WHEEL COMPLETELY LOCKED UP AND THE CAR SHUT OFF. I ALMOST CAUSED A MAJOR ACCIDENT A CAR HAD TO SWERVE AROUND ME. I MANAGED TO GET TO THE SIDE OF THE ROAD IN THE CONSTRUCTION AREA. THIS HAS TO BE LOOKED INTO. I'VE RESEARCHED ONLINE AND I SEE A LOT OF IMPALAS ARE HAVING THIS SAME PROBLEM. THIS SHOULD BE CONSIDERED A SERIOUS SAFETY RISK. *TR

TRAVELING AT HIGHWAY SPEED, THE DASHBOARD LIGHTS CAME ON AND THE VEHICLE BEGAN TO LOSE SPEED. STEPPING ON THE ACCELERATOR PEDAL HAD NO EFFECT AND I MOVED TO THE RIGHT LANE, I HAD BEEN PASSING ANOTHER VEHICLE AT THE TIME. I DROVE THE CAR AT THE SPEED WHICH IT PERMITTED WITH MY FOUR-WAY BLINKERS ON UNTIL I ARRIVED HOME. IT WAS AT NIGHT AND THERE WAS NO WHERE ELSE TO GO. THE NEXT DAY, THE PROBLEM WAS NOT EVIDENT, BUT I TOOK IT TO THE DEALER FROM WHOM I HAD PURCHASED IT, USED. THAT DEALER WAS UNABLE TO ASCERTAIN THE PROBLEM, AND TOOK THE CAR TO A LOCAL CHEVROLET FRANCHISE WHERE IT WAS "REPAIRED" AND RETURNED. SEVERAL DAYS LATER, THE SAME PROBLEM OCCURRED WHEN I WAS ENTERING A HIGHWAY I COULD NOT ACCELERATE INTO TRAFFIC. THIS TIME, AS IT HAPPENED DURING THE DAY, I AGAIN TOOK IT TO MY DEALER. IT WAS SUGGESTED THAT I DEAL DIRECTLY WITH THE LOCAL CHEVROLET DEALER TO WHOM HE HAD TAKEN THE CAR THE FIRST TIME. THAT DEALER HAD IT FOR SEVERAL DAYS. THE DEALERSHIP CONTACTED THE FACTORY DIRECTLY FOR INSTRUCTIONS TO FIX THE PROBLEM, . TO DATE, THERE HAS BEEN NO RE-OCCURRENCE OF THIS, NOR ANY OTHER PROBLEM. THE FIRST VISIT FOR REPAIR COST ABOUT $200 AND THE SECOND $500. I CONTACTED GENERAL MOTORS DIRECTLY AND THEY AGREED TO REFUND $250 EARLIER THIS YEAR. *TR

WHILE ON FREEWAY CHECK ENGINE LIGHT AND TRACTION CONTROL CAME ON AND DISPLAY READ "REDUCED ENGINE POWER" AND "SERVICE STABILITRAK" APPARENTLY A VERY COMMON AND DANGEROUS ISSUE THAT HAS NOT BEEN RECALLED. I BOUGHT THIS CAR FOR MY WIFE A COUPLE MONTHS AGO USED AND IT HAS GONE OFF MULTIPLE TIMES. THE ENGINE SHIFTS GEARS VERY ROUGH AND POWER IS LOST. SCHEDULED TO GO TO DEALERSHIP TOMORROW BUT LOOKS LIKE IT WILL COST ME. *TR

CRANKED UP THE CAR TO GO HOME. STABILITY LIGHT AND "ENGINE" LIGHT WAS ON. WHILE ON THE INTERSTATE PASSING A TRUCK THE ENGINE DIED. DISPLAY CENTER INDICATED SERVICE STABILITY TRACK AND REDUCED ENGINE POWER. COASTED OVER TO RT. SHOULDER. CAR WOULD NOT RESTART FOR ABOUT 30 SEC. CRANKED IT UP AND MADE IT HOME. TROUBLE CODE IS P2138 WHICH SEEMS TO INDICATE THE THROTTLE POSITION SENSOR D/E VOLTAGE. WILL TAKE TO DEALER IN AM. *TR

BACKING OUT OF MY GARAGE WHEN CHECK ENGINE, STABILITRAK PROBLEM, REDUCED ENGINE POWER LIGHT CAME ON MESSAGE PORTION OF DASH.DROVE UNDER REDUCED POWER, MAX 30 MPH, TO DEALER, APPROXIMATELY 15 MILES. LEFT CAR WITH DEALER FOR APPROXIMATELY 2 DAYS. INVOICE FROM DEALER SAID, DIAGNOSE CODE P2135, TRACE TO THROTTLE POSITION SENSOR-BULLETIN REPLACED SENSOR ASSEMBLY, GM 19300180 SENSOR KIT, NO CHARGE TO ME UNDER POWER TRAIN WARRANTY. TODAY, APRIL 30, 2014, SAME WARNING LIGHT CAME ON, STABILITRAK PROBLEM, REDUCED POWER, WHEN BACKING OUT OF SAME GARAGE. PARKED CAR BACK IN GARAGE AND CALLED DEALER, HAVE APPOINTMENT TOMORROW. HOPE THEY CAN PERMANENTLY FIX PROBLEM AS DRIVING UNDER REDUCED POWER IS DANGEROUS AND CAN OCCUR ANYWHERE. *JS

I WAS DRIVING ON THE HIGHWAY WHEN "REDUCED ENGINE POWER, ENGINE LIGHT,ELECTRONIC STABILI TREK" WARNING LIGHTS CAME ON. MY RPM WAS RACING UPWARDS BUT MY ENGINE NEVER RAN HOT. I GOT OFF THE HIGHWAY BECAUSE OF THE WARNINGS AND LOST OF ACCELERATION. I GOT HOME AND CALLED GM CUSTOMER SERVICE WHO ADVISED ME OF NO RECALL FOR THAT PROBLEM AND CONNECTED ME TO A LOCAL DEALERSHIP REPAIR SHOP AND I MADE AN APPOINTMENT. RESEARCHING THE CAR MALFUNCTION, I FOUND NUMEROUS POSTINGS ABOUT THE AFOREMENTIONED PROBLEM. I TOOK THE CAR TO DEALERSHIP AND MECHANIC CALLED AND SAID I NEEDED A APP SENSOR / PEDAL WHICH IS A FACTORY ONLY PART. I OK'D THE SERVICE WORK. THE NEXT DAY (APRIL 18TH,2014) THE ENGINE LIGHT CAME ON BRIEFLY AND THE CAR WAS HESITATING AGAIN, I CALLED THE DEALERSHIP REPAIR SHOP AT 2:35 AND SPOKE WITH MECHANIC THAT REPAIRED MY CAR AND EXPLAINED THE PROBLEM. MECHANIC ASKED ME IF THE LIGHT WAS STAYING ON I REPLIED NO AND HE STATED THE MECHANICS ARE LEAVING IN HOUR. I ASKED THE MECHANIC IF IT WAS SAFE TO DRIVE CAR UNTIL MONDAY, HE REPLIED YES. *TR
