2009 Chevrolet Impala

WHILE ACCELERATING AFTER A STOP AT A RED LIGHT THE THROTTLE LOST RESPONSIVENESS. THE CHECK ENGINE LIGHT CAME ON AND THREE MESSAGES APPEARED ON THE DASH BOARD DISPLAY. 1. 'SERVICE STABILITRACK' 2. 'TRACTION CONTROL MALFUNCTION' FOLLOWED BY 3. 'REDUCED ENGINE POWER'. VEHICLE WOULD NOT ACCELERATE BEYOND 40MPH. I WAS ON A DOWN RAMP HEADING TOWARD A HIGHWAY WITH NO BREAKDOWN LANE AVAILABLE. VERY DANGEROUS SITUATION. NEXT MORNING I BROUGHT THE VEHICLE INTO A LOCAL CHEVROLET DEALER AND CODE P2138 REVEALED "ACCELERATOR PEDAL/SENSOR FAILURE." REPAIR COST $265. MANY OTHER CHEVROLET OWNERS COMPLAIN OF THIS SAME ISSUE AND THE DANGEROUS SITUATION THE ACCELERATION LOSS CAUSES. PLEASE SEE THIS EDMUNDS.COM BLOG WITH DOZENS OF OTHERS COMPLAINING OF THIS SAME ISSUE.

I WAS DRIVING 55MPH 4/10/2013 THEN I GO DOWN TO 40 AND MESSAGE SENSOR SAYS ENGINE LOW PRESSURE OR SOMETHING LIKE THAT SO I TOOK IT TO AUTO ZONE AND THEY SAID THROTTLE SENSOR MAKE THE CHECK ENGINE LIGHT COME ON NOW 4/27/2013 THE LIGHT CAME ON AGAIN NOW THEY SAYING THE PEDAL SENSOR AND THE LOW ENGINE PRESSURE CHECK ENGINE LIGHT IS ON AGAIN. *TR

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE TRAVELING 65 MPH, THE VEHICLE STALLED. THE VEHICLE WAS MOVED TO THE SHOULDER AND RESTARTED. THE VEHICLE RESUMED NORMAL FUNCTION THEN THE FAILURE RECURRED. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHERE IT WAS FOUND THAT THE THROTTLE CONTROL SENSOR HAD FAILED. THE VEHICLE WAS REPAIRED BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE WAS 67,000.

AS I WAS DRIVING ON THE INTERSTATE ALL OF A SUDDEN I FEEL THE VEHICLE SLOW DOWN AND THE MESSAGE CENTER DISPLAYS "TRACTION CONTROL OFF" "ENGINE POWER REDUCED". I WAS TRAVELING ABOUT 65MPH AT THE TIME HOWEVER TO MAINTAIN THAT SPEED AFTER THIS HAPPENED I HAD TO PRESS THE GAS PEDAL FURTHER. THE STABILITRAK LIGHT STAYED ON FOR A DAYS ALSO. *TR

DRIVING ABOUT 25MPH ON FEEDER, ENGINE REDUCED SPEED WITHOUT ANY WARNING. THEN PANEL SHOWED TRACTION CONTROL AND ENGINE REDUCED SPEED. I WAS THANKFUL I WAS GOING HOME. TERRIFIED EXPERIENCE. CHECKED ONLINE. OTHER PEOPLE BAD THE SAME EXPERIENCE AND ALMOST COSTING LIVES BECAUSE OF CLAIMS THE ENGINE STOPS ALSO WITHOUT WARNING. EVERYONE SAID FROM ACCELERATION PEDAL. WHY WAS THIS NOT RECALLED AND I'M HAVING TO TAKE THE CAR TO A SHOP. I CALLED A DEALER BUT DIDN'T OFFER MUCH ASSISTANCE. THIS IS DANGEROUS! *TR

I HAVE A 2009 CHEVY IMPALA LT & WAS DRIVING APROXIMATELY 50MPH DOWN THE ROAD WHEN ALL OF A SUDDEN THE "SERVICE TRACTION CONTROL MESSAGE CAME ON, THE CHECK ENGINE LIGHT CAME ON & ENGINE POWER WILL BE REDUCED MESSAGE CAME ON". THE CARS SPEED DROPPED DOWN TO ABOUT 40MPH & WOULD HARDLY GO. I DIDN'T KNOW WHAT WAS GOING ON. IT REALLY SCARED ME BECAUSE I THOUGHT MY CAR WAS GOING TO CUT OFF. I DID GET TO WORK SAFELY BUT I AM TERRIFIED TO DRIVE THIS CAR. I SEARCHED MESSAGE BOARDS ON THE INTERNET & CAME ACROSS 297 MESSAGES FROM OTHER PEOPLE WHO OWN GM VEHICLES THAT THIS HAS HAPPENED TO. A COUPLE OF PEOPLE SAID THEIR CARS ACTUALLY CUT OFF ON THEM WHILE GOING DOWN THE HIGHWAY AT A HIGH RATE OF SPEED. ONE WAS INVOLVED IN AN ACCIDENT. THE PROBLEM FROM WHAT I HAVE READ HAS SOMETHING TO DO WITH THE ACCELERATOR PEDAL POSITION SENSOR OR THROTTLE BODY. FROM WHAT I HAVE READ GM KNOWS ABOUT THIS PROBLEM BUT HAS NOT DONE A RECALL ON THIS. A COUPLE OF PEOPLE POSTED THAT THEIR LOCAL CHEVY DEALERSHIP COVERED THE REPAIR EVEN THOUGH THEIR CARS WERE NO LONGER UNDER WARRANTY. I CALLED MY LOCAL CHEVY DEALERSHIP AND THEY TOLD ME THAT THEY COULDN'T DO ANYTHING ABOUT IT. THEY SAID THAT I WOULD HAVE TO PAY FOR REPAIRS MYSELF. TO ME, THIS IS UNACCEPTABLE. I COULD HAVE A WRECK & GET KILLED OR KILL SOMEONE ELSE. I DON'T UNDERSTAND WHY A COMPANY WOULD CLEARLY KNOW ABOUT A PROBLEM WITH THEIR VEHICLES AND DO NOTHING ABOUT IT. I THINK THAT GM SHOULD COVER THE REPAIRS TO MY VEHICLE AND TO ANY OTHERS THAT ARE HAVING THIS PROBLEM. *TR

I HAVE A 2009 CHEVROLET IMPALA THAT I PURCHASED IN 2010. SEVERAL MONTHS LATER, THE CAR BEGAN TO READ CHECK ENGINE, SERVICE TRACTION CONTROL, REDUCED ENGINE POWER, THEN STALLS AND JERKS WHILE I'M DRIVING. IT HAPPENS INTERMITTENTLY. I TOOK IT TO AUTOZONE TO HAVE THEM CHECK THE COMPUTER CODE. THEY SAID IT WAS THE ACCELERATOR PEDAL POSITION SENSOR. THE CAR ONLY HAS ABOUT 50,000 MILES ON IT. I AM PLANNING O TAKING IT TO THE DEALERSHIP BECAUSE IT IS HAPPENING MORE OFTEN AND I AM AFRAID THAT I WILL HAVE AN ACCIDENT AS A RESULT OF THIS PROBLEM. *TR

I WAS DRIVING HOME FROM WORK ON MY 2009 IMPALA, I WAS ALREADY CONCERNED BECAUSE THE CAR HAD THE REDUCED POWER ENGINE AND TRACTION CONTROL ENABLED DISPLAY. WHEN ALL OF A SUDDEN I GET A MESSAGE SAYING DISABLE THROTTLE BODY AND THE STAR FELT LIKE IT WAS GOING TO STOP. THE GOOD THING I WAS ON THE SLOW LANE SO I WAS ABLE TO PULL OVER . I DON'T UNDERSTAND WHY MY CAR IS DOING THIS AND WHY GM IS NOT ISSUING A RECALL TO FIX THIS PROBLEM. THEY PROBABLY NEED SOMEONE TO DIE SO THAT THEY CAN TAKE THIS SERIOUS. *TR

WHILE TRAVELING ON I-95 AT ABOUT 75MPH, THE FOLLOWING MESSAGE APPEARED ON THE DASH," REPAIR TRACTION CONTROL SYSTEM... ENGINE POWER IS REDUCING". THANKFULLY, I WAS APPROACHING A REST AREA, SO I SAFELY COASTED TO A SECURE AREA. AFTER ESCAPING A POTENTIALLY FATAL ACCIDENT, I RESEARCHED THIS TRACTION CONTROL MESSAGE, ONLY TO DISCOVER INNUMERABLE CUSTOMERS HAD THE SAME PROBLEM. THIS ISSUE SHOULD BE INVESTIGATED SINCE IT IS A UNIVERSAL PROBLEM, ONE THAT IS ENDANGERING THE LIVES OF GM AND OTHER DRIVERS ON THE HIGHWAY. *TR
