2009 Chevrolet Impala

I WAS DRIVING THROUGH A HILLY/ CURVY AREA OF ROAD WHEN MY REDUCED ENGINE POWER, TRACTION CONTROL, AND THROTTLE BODY DISABLED MESSAGE POPPED UP. JUST THEN I HAVE NO POWER, NO BRAKES AND NO STEERING,AT ALL! I ALMOST CRASHED WITH MY TWO KIDS IN THE CAR! UPON LOOKING UP THIS ISSUE I FIND THAT IT IS A VERY COMMON ISSUE IN IMPALAS. SOME PEOPLE HAVE HAD THIS ISSUE WHILE PASSING CARS, OR THE FREEWAYS AND MORE. TO ME THIS IS QUITE A SAFETY CONCERN SINCE YOU HAVE NO POWER TO DO ANYTHING...NOTHING AT ALL. I DON'T SEE HOW THERE IS STILL NO RECALL ON THIS ISSUE WHEN THERE ARE SO MANY REPORTED PROBLEMS AND A HUGE SAFETY RISK!! *TR

THIS THE SECOND TIME THIS HAS HAPPENED. WIFE WAS DRIVING DOWN THE FREEWAY WHEN TRACTION CONTROL AND CHECK ENGINE LIGHTS CAME ON. CAR WENT INTO REDUCED POWER MODE AND FINALLY DIED WHILE STILL MOVING. LOST POWER STEERING AND FINALLY BROUGHT CAR TO A STOP ON LEFT INSIDE OF EXPRESSWAY. AFTER A SHORT TIME SHE WAS ABLE TO RESTART THE CAR AND LIMP HOME. NOTE THAT THE CRUISE CONTROL WAS ON, BUT I DO NOT KNOW IF IT WAS SET. HAD THE CODES READ THAT INDICATED A THROTTLE POSITION SENSOR CAUSED THE FAULT. THERE ARE TWO SENSORS WHICH HAVE TO AGREE AND IF THEY DON'T CAR WILL GO INTO REDUCED POWER MODE. WHEN SHE GOT HOME I FOUND ONLY THE CHECK ENGINE LIGHT ON. I HAVE IN THE PAST MOVED THE WIRES ON THE BRAKE FLUID SENSOR TO GET THE CHECK ENGINE LIGHT TO GO OFF. NOT KNOWING EXACTLY HOW ALL OF THESE DIFFERENT SYSTEMS ARE TIED TOGETHER, I TEND TO THINK THAT THE CARS COMPUTER IS THE PROBLEM WHICH SETS OFF ALL THE DIFFERENT WARNING LIGHTS ON THE DASH. I WENT TO THE CHEVY DEALERSHIP AND THE SERVICE ADVISOR ASKED IF THIS WAS A RECALL ISSUE. I THOUGHT THIS WAS SOME WHAT STRANGE. AFTER READING COMPLAINTS ON THE NET I CAN SEE WHY SHE MIGHT HAVE THOUGHT IT WAS A RECALL ISSUE. THE THROTTLE BODY PART IS $300 DOLLARS PLUS LABOR RATE OF $105/HR. AS OF NOW I CANNOT FIND ANY RECALLS FOR THIS ISSUE. NHTSA NEEDS TO LOOK AT THIS PROBLEM BECAUSE THE LOSS OF STEERING WITH ALL SYSTEMS DUE TO MOTOR STALLING WHILE IN MOTION IS A HAZARD TO EVERYONE. *TR

I AM HAVING PROBLEMS WITH MY 2009 CHEVY IMPALA, IT STARTED AT 43K, THE ACCELERATION PEDAL WAS CHANGED WHEN THE REDUCED ENGINE POWER/SERVICE TRACTION CONTROL CAME ON. THEN AGAIN AT 100K SAME PROBLEM, THIS TIME THE DEALERSHIP TOLD ME IT WAS A BAD THROTTLE POSITION SENSOR, THE THROTTLE BODY NEEDED TO BE CHANGED. I CHANGED IT, BUT IT CAME BACK AGAIN LESS THEN 3K MILES. I REPLACED THE THROTTLE BODY AGAIN. 3K LATER SAME THING. THE PROBLEM IS WHEN IT IS RAINING THE THROTTLE SENSORS GO NUTS. I TOOK THE CAR TO ADVANCE AUTO AND READ THE CODES, SAME AS BEFORE, P0121, P2176, THROTTLE POSITION SENSOR. ONCE IN A WHILE YOU CAN REMOVE THE BATTER LINES AND UNPLUG THE THROTTLE BODY AND MASS AIR FLOW SENSOR TO GET IT TO RESTART. OTHER TIMES YOU HAVE TO GO TO ADVANCE OR AUTOZONE TO CLEAR THE CODES IN ORDER TO GET IT TO RUN LONG ENOUGH FOR A SUNNY DAY. I HAD ONE OCCURRENCE WERE THE CAR WOULD NOT START AND IT SAID SERVICE THROTTLE POSITION. THE THROTTLE SENSOR NEEDS TO BE RECALLED BEFORE SOMEONE GET KILLED. I HAVE RENAMED MY CAR TO THE FORD IMPALA. FOUND ON THE ROAD DEAD IMPALA. *TR

WHILE MERGING ONTO A TWO LANE HIGHWAY MY IMPALA SUDDENLY LOST POWER AND I RECEIVED A "LOW ENGINE POWER" WARNING AND THEN " SERVICE TRACTION CONTROL" THE CHECK ENGINE LIGHT COMES ON AND THE CAR RUNS ROUGHLY AT REDUCED POWER - YOU NEED TO PULL OVER AND SHUT THE CAR OFF UNTIL YOU CAN START IT AGAIN. THIS IS A VERY DANGEROUS ISSUE THAT GM REFUSES TO ACKNOWLEDGE. IN THIS INSTANCE I HAD MY DAUGHTER IN THE CAR - I ALSO LOST THE POWER BRAKES. I HAVE BEEN TO TWO CHEVROLET DEALERS AND A BUICK DEALER BECAUSE THIS HAS HAPPENED SEVERAL TIMES OVER THE PAST YEAR AND A HALF. THEY REPLACED MY THROTTLE BODY, OIL SENSOR, BATTERY AND SOMETHING ELSE AND CHARGED ME OVER $2000 FOR THE THREE VISITS AND I AM STILL EXPERIENCING THE ISSUE. I HAVE ALSO BEEN TO A LOCAL REPAIR SHOP AND HAD THE WIRING HARNESS CHANGED AND HAD SEVERAL DIAGNOSTICS DONE. AFTER ALL THIS THE PROBLEM STILL EXISTS. I NORMALLY DON'T WRITE LETTERS BUT, THIS IS A VERY DANGEROUS SITUATION AND MANY OTHERS ARE EXPERIENCING THE SAME THING BASED ON THE MESSAGE BOARDS I HAVE READ. MY CONCERN IS THAT GM REFUSED TO HELP OR ISSUE A RECALL. MY FEAR IS THAT SOMEONE GETS SERIOUSLY HURT OR KILLED BEFORE GM ANSWERS FOR THIS. THIS IS NOT GOOD FOR GM. MY HOPE IS THAT SOMEONE FINALLY ADDRESSES THIS ISSUE BEFORE SOMEONE IS KILLED. IN MY LAST COMMUNICATION WITH GM - I WAS TOLD TO TAKE MY CAR TO A DEALER FOR A DIAGNOSTIC AT MY OWN EXPENSE. SO, BASICALLY I AM ON MY OWN AND THEY OFFERED TO DO NOTHING. JUST NOT RIGHT! *TR

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. THE CONTACT STATED THE ACCELERATOR PEDAL POSITION SENSOR FAILED AND CALLED THE VEHICLE TO SLOW DOWN TO 40 MPH. THE CONTACT STATED THAT THE TRACTION CONTROL LIGHT ILLUMINATED ON THE INSTRUMENT WHEN THE FAILURE OCCURRED. THE SENDING UNIT WAS REPLACED AND THE VEHICLE BEGAN TO PERFORM NORMALLY. THE DEALER INFORMED THE CONTACT THIS WAS A KNOWN PROBLEM. THE FAILURE AND CURRENT MILEAGE WAS 81,506. *TR

I WAS DRIVING AND THE MESSAGE LOOSING ENGINE POWER AND STABILITY CONTROL SYSTEM STARTED FLASHING. THE CAR STARTED SLOWING DOWN AND I COULDN'T STEER. I HAD SOMEONE LOOK AT IT AND THEY TOLD ME WHAT WAS WRONG. I ALSO LOOKED ONLINE AND SAW THE MANY COMPLAINTS AND GM IS AWARE. I PARKED THE CAR UNTIL I AM ABLE TO HAVE IT SERVICED. THE ISSUE SEEMS TO BE A ACCELERATOR SENSOR SWITCH MALFUNCTION. IF I WAS GOING AT A FASTER SPEED OR WAS ON THE HIGHWAY THIS COULD HAVE CAUSE AN ACCIDENT. I CALLED GM AND THEY STATED THEY SEE NO REPORTED ISSUES. *TR

THE FIRST TIME MY ENGINE CONTROL LIGHTS TURNED ON WAS WHEN I WAS BACKING UP OUT OF A PARKING SPACE. AS TIME WENT BY THE LIGHTS STARTED TO COME ON CONTINUOSLY. THE LIGHTS KEPT TELLING ME TO SERVICE TRACTION CONTROL. THEN THE CHECK ENGINE LIGHT CAME ON. I THEN TOOK MY CAR INTO FRIENDLY CHEVY IN MINNESOTA. THEY DID 3000 DOLLARS WORTH THE WORK AND NEVER FIXED THE PROBLEM I WENT IN FOR.THE LIGHTS ARE STILL COMING ON AND IT SCARES THE LIFE OUT OF ME.. I PAID 9,000 FOR IT. ALSO PUT IN 3000.00 INTO IT FOR REPAIRS. WHAT A PIECE OF JUNK. I TRIED TO TAKE IT BACK BUT THEY SAID THERE WAS NOTHING I COULD DO ABOUT IT EXCEPT TRADE IT IN FOR 3000.00 LESS THEN WHAT I PAID FOR IT.ABSOLUTELY UNACCEPTABLE!!! I WILL NEVER BUY ANOTHER CHEVROLET AGAIN. TERRIBLE SERVICE. *TR

ALARM CAME ON THAT READ SERVICE TRACTION CONTROL - ENGINE POWER REDUCED. I WAS TRYING TO PASS A SEMI-TRAILER WITH ANOTHER CAR DIRECTLY BEHIND ME. THE ENGINE SUDDENLY WENT DEAD AND ANOTHER ALARM READ STARTING DISABLED. THERE WAS NOTHING I COULD DO. IF THE CAR BEHIND ME HAD NOT NOTICED MY CAR ROLLING TO A STOP I WOULD HAVE BEEN REAR ENDED AND SENT INTO THE TRUCK. THIS IS A SERIOUS LIFE-THREATENING SITUATION AND IT NEEDS TO BE ADDRESSED IMMEDIATELY. *TR

I RECENTLY PURCHASED A CHEVROLET IMPALA LTZ 2009 MODEL A FEW MONTHS AGO AND IT HAS 82,000 ON IT. WHILE DRIVING ON THE HIGHWAY MY CHECK ENGINE LIGHT CAME ON. IT SAID THAT I HAD A BAD ACCELERATOR SENSOR. FOLLOWED BY A FLASHING LIGHT THAT SAID MY CAR HAD REDUCED ENGINE SPEED. I HAVE LOOKED UP MANY TIMES ABOUT THIS ISSUE WITH MY CAR AND MANY OTHER PEOPLE HAVE HAD PROBLEMS WITH A BAD GAS PEDAL. GM KNOWS AND I'M CONFUSED AS TO WHY THEY NEVER ASKED FOR A RECALL ON THIS. *TR
