2009 Chevrolet Impala

I WAS ON THE INTERSTATE, GOING THE SPEED LIMIT. I HAD THE CRUISE CONTROL ON WHEN THE CAR ALERTED ME THAT THE ENGINE POWER REDUCED AND SERVICE TRACTION CONTROL. I CONTINUED TO DRIVE AS THESE MESSAGES HAVE APPEARED ON MY CAR BEFORE. I TRAVELED ANOTHER 40 MILES ALONG THE INTERSTATE AND WAS ABOUT A MILE FROM MY EXIT. I WAS PASSING AN OVER-SIZED TRACTOR TRAILER GOING UP HILL WHEN THE CAR DISPLAYED STARTING DISABLED THROTTLE SERVICE AND THE CAR SHUT OFF. I WAS IN THE LEFT LANE AND HAD TO INITIATE MY EMERGENCY LIGHTS AND WAIT FOR THE TRACTOR TRAILER TO PASS ME SO I COULD MOVE THE CAR OVER TO THE RIGHT SHOULDER. AS THE CAR WAS COMPLETELY SHUTOFF AND WAS JUST COASTING, I HAD TO FIGHT THE STEERING WHEEL TO CONTROL THE CAR. I FEEL LIKE HAD MY SITUATION WAS JUST A LITTLE DIFFERENT, THE CAR COULD HAVE CAME TO A COMPLETE STOP IN THE MIDDLE OF THE INTERSTATE WITH CARS TRAVELING 70+ MPH AND POSSIBLY CAUSED A CRASH. I'VE ALREADY REPLACED THE THROTTLE POSITION SENSOR AND THAT REMEDIED THE SITUATION FOR A COUPLE MONTHS. THIS A HIGHLY DANGEROUS OCCURRENCE THAT I KNOW IS COMMON WITH THE IMPALA'S AS I'VE HEARD IT HAPPENING TO SEVERAL OTHER PEOPLE OWNING IMPALA'S.

I HAVE GOTTEN SERVERAL ERROR WITH CHECK SERVICE TRACTION CONTROL SINCE I PURCHASE THE USE CHEVELOT IMPALA LS 2009 BACK IN 2012. IT ALREADY HAD 88,000 MILES ON IT AND ABOUT A YEAR AFTER I HAD THE CAR I STARTED TO GET THIS MESSAGE. THE SECOND IT OCCURED I WAS ON FREEWAY AND THE ERROR CAME ON AND AFTER I GOT OFF ON THE EXIT MY CAR SHUT DOWN FOR ABOUT 5 MINUTES BEFORE I WAS ABLE TO START IT BACK UP. NOW I HAVE THIS ERROR THIS TIME AND EVERY NOW AND AGAIN IT FEEL LIKE THE CAR WANTS TO JERK EVERY NOW AND AGAIN AND IF I PRESS THE GAS PEDAL DOWN TO QUICKLY THE LIGHT ERROR FLASH WITH THE CAR SIGN SWIRLING MESSAGE ON THE DASHBOARD.

I WAS DRIVING ON THE HIGHWAY WHEN THE SERVICE TRACTION CONTROL CAME UP ON THE DASH ALONG WITH THE TRACTION CONTROL LIGHT, WITH IN SECONDS OF THIS HAPPENING THE CAR READ REDUCED ENGINE POWER. THE CAR IMMEDIATELY LOST POWER AND SLOWED DOWN TO A MAXIMUM OF 25 MPH. THIS SUDDEN LOSS OF POWER CAUSED THE CARS BEHIND ME TO NEARLY MISS REAR-ENDING ME. I HAD TO DRIVE IN THIS CRIPPLED MODE 10 MILES TO REACH THE CLOSEST EXIT. IT IS DUE TO A FAULTY THROTTLE POSITION SENSOR. THIS SEEMS TO BE A VERY COMMON PROBLEM WITH THESE VEHICLES AND CAN CAUSE A SUDDEN LOSS OF POWER.

TRAVELING ON HIGHWAY AT 70 MPH. SERVICE TRACTION, REDUCED ENGINE POWER, SERVICE ENGINE LIGHTS CAME ON, CAR WAS SHAKING, EVERYTHING WAS SHUTTING DOWN. FORTUNATELY IT WAS NOT RUSH HOUR AND I WAS ABLE TO PULL OFF ROAD. I WAS ON A TOLL ROAD THAT AAA CAN NOT RESPOND. I WAITED ABOUT 20 MINUTES AND STARTED THE CAR AND EVERYTHING WAS FINE. TOOK CAR TO OUR MECHANIC, THERE WAS A SERVICE BULLETIN, TO REPLACE THROTTLE BODY ASSEMBLY. SINCE THEN, 2 LETTERS FROM GM ABOUT COVERING COST OF THROTTLE SENSOR, BUT NOT ASSEMBLY. GM IS NOT TAKING CARE OF THE REAL PROBLEM, THE WHOLE ASSEMBLY NEEDS TO BE REPLACED, NOT JUST THE SENSOR! I'VE KEPT THE PART AND INVOICE AND LETTERS FROM GM, THEY SHOULD JUST RECALL BEFORE IT TURNS INTO A CLASS ACTION LAWSUIT!

MY CAR WAS TAKEN INTO THE DEALER TO CHECK ON THE "SERVICE ENGINE SOON" WARNING AND I WAS INFORMED THAT THE COMPUTER SHOWED IT AS AN APPS ISSUE. THEY CHECKED THE APPS AND I WAS INFORMED THAT THEY COULDN'T FIND ANYTHING WRONG AND THAT IT HAD BEEN RESET WITHIN THE COMPUTER SYSTEM AND I WAS GOOD TO GO. TWO MONTHS LATER WHILE TRAVELING AT A SPEED OF 55 MPH ON A HIGHWAY, THE SERVICE ENGINE LIGHT CAME ON, SERVICE STABILITRAK APPEARED ON THE INSTRUMENT PANEL, TRACTION CONTROL OFF LIGHT UP ON THE INSTRUMENT PANEL AND THEN THE RING TONE AND THE "ENGINE POWER IS REDUCED" CAME ON THE INSTRUMENT PANEL. THE NEXT THING I KNEW WAS THAT I HAD ABSOLUTELY NO ACCELERATION AT ALL! I WAS EXTREMELY FORTUNATE THAT THE VEHICLES BEHIND ME WERE FAR ENOUGH BEHIND ME AND I WAS ABLE TO GET OFF OF THE ROAD AND ON TO THE SHOULDER. HAD THAT NOT BEEN THE CASE THERE COULD HAVE BEEN A SERIOUS ACCIDENT CAUSING NUMEROUS INDIVIDUALS TO BE INJURED OR KILLED. I HAD THE VEHICLE TOWED AND CHECKED AND IT WAS DEFINITELY THE APPS (ACCELERATOR PEDAL PERFORMANCE SENSOR) THAT WAS DEFECTIVE. NOW NEARLY 2 YEARS LATER, IT HAS HAPPENED AGAIN. THE EXACT SAME WARNINGS CAME ON AGAIN, ONLY THIS TIME I WAS TRAVELING IN INCLEMENT WEATHER AND DURING RUSH HOUR TRAFFIC. THERE ARE NUMEROUS COMPLAINTS REGARDING THE EXACT SAME ISSUE AND CHEVROLET/GM NEEDS TO ISSUE A RECALL AS THE APPS IS DEFECTIVE. IF NO RECALL IS ISSUED IT IS A MATTER OF TIME BEFORE INNOCENT PEOPLE ARE KILLED.

MY NAME IS [XXX] AND I PURCHASED A 2009 CHEVY IMPALA, WITH 123,000 MILES ON IT, IN AUGUST 2015 FROM MAC CHURCHILL AUTO MALL IN BEDFORD, TEXAS. I HAVE HAD NO PROBLEMS WITH THIS CAR SINCE ITS PURCHASE UNTIL NOVEMBER 29TH. WHILE EN ROUTE TO EMORY, TEXAS, MY CAR STARTED DISPLAYING "ENGINE POWER IS REDUCED" AND "SERVICE TRACTION CONTROL" MESSAGES. ABOUT 99% OF THE WAY THERE, I SUDDENLY GOT A LURCH AND MY CAR SLOWED DOWN, WITH STEERING AND BRAKING NOT WORKING. I WAS ABLE TO GET MY CAR OFF THE HIGHWAY SAFELY BUT HAD TO USE MY EMERGENCY BRAKE TO STOP MY VEHICLE AND GET IT TURNED OFF. I TRIED REPEATEDLY FOR SEVERAL MINUTES TO GET IT GOING AGAIN, BUT IT WOULD NOT START. AFTER ABOUT FIVE MINUTES, THE CAR RESTARTED NORMALLY AND HAS PERFORMED FLAWLESSLY SINCE. HOWEVER, I AM CONCERNED. I'VE HAD A GARAGE PULL AND DIAGNOSE THE PROBLEM. THE ERROR CODES THAT WERE PULLED ARE P2122 AND P2138 ,REGARDING THE ACCELERATOR PEDAL POSITION SENSOR. I'VE RESEARCHED THIS AND THIS APPEARS TO BE A COMMON PROBLEM FROM WHAT I'VE BEEN ABLE TO ASCERTAIN FROM MY RESEARCH. BUT I'M CONFUSED AS TO WHETHER THIS IS A RECALL ITEM BASED UPON THIS: HTTP://WWW.NAIOA.COM/V2/MODULES.PHP?NAME=FORUMS&FILE=VIEWTOPIC&T=49934 . I'M NOW TRYING TO UNDERSTAND WHETHER I CAN GET THIS FIXED BECAUSE I'M NOT SURE THIS IS COVERED UNDER MY USED CAR WARRANTY AND I DO NOT FEEL COMPELLED TO PAY FOR A REPAIR THAT GM HAS BEEN AWARE OF BUT FAILED TO NOTIFY MY DEALERSHIP OR ME AS A OWNER, UNTIL I GOT A LETTER ON 12/9/15 INDICATING THAT THERE MAY BE A PROBLEM...WELL AFTER I STARTED HAVING PROBLEMS. I WANT GM TO FIX THIS AT THEIR EXPENSE. IT IS A SAFETY HAZARD HERE IN THE DFW AREA BECAUSE THIS COULD REOCCUR WHILE I'M IN HEAVY TRAFFIC AND HAVE NO WAY TO STOP BEFORE SOMEONE HITS ME OR I HIT SOMEONE.
