The contact owns a 2009 Chevrolet Impala. The contact stated that while driving at an undisclosed speed on separate occasions, the messages “Reduce Engine Power” and "Service Traction Control" were displayed on the instrument cluster, and the check engine warning light was illuminated. Additionally, the contact stated that the failure reoccurred while driving on a bumpy road surface and while turning the steering wheel. The vehicle was taken to an independent mechanic, where it was diagnosed that the throttle position sensor had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that her father used an OBD reader and retrieved codes indicating that the throttle position sensor was faulty and needed to be replaced. The vehicle was repaired; however, the failure persisted. The contact stated that while driving at an undisclosed speed, the vehicle decelerated unintendedly. The vehicle was taken to an unknown dealer, who informed the contact that the VIN was not included in a recall. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 169,000.

While driving the car it would pop up a message saying “ENGINE POWER REDUCED”. Today while driving it home it popped up with a message saying “STARTING DISABLED, SERVICE THROTTLE” and then the car wouldn’t drive and I had to pull over on the side of the road. For months now when I drive and accelerate at times the car would almost grind. I believe it has to do with the traction control or the transmission.

My car has started slowing down abruptly and displaying Engine Power has been Reduced at random times, but has become more frequent. I have had an independent service center tell me it was the throttle body, so they replaced it. That didn't fix it, so they replaced the accelerator pedal/sensor. It still is happening and when on the interstate, it is so dangerous to slow down with no warning because you can get rear ended quite easily. This first started August 2021 when my wife and I started on a vacation and had to turn around and go home and is still happening, only more frequent. This past Saturday 7/16, I was traveling on Interstate 77 and the engine power kept cutting down about every 10 minutes, so I had to pull over and cut the engine off for a while until it reset. I can't trust it to go anywhere.

TO WHOM IT MAY CONCERN: I HAVE A 2009 CHEVY IMPALA WITH 100,000 MILES ON IT. THE 1ST TIME THIS ISSUE HAPPENED, I WAS DRIVING SLOWLY, ON A SIDE STREET, IN JULY 2019. OUT OF THE BLUE, THE FOLLOWING WARNINGS APPEARED: ENGINE POWER IS REDUCED, SERVICE STABILITRAK, SERVICE TRACTION CONTROL. IMMEDIATELY MY CAR STARTED RUNNING HORRIBLY (IT DIDN'T WANT TO GO, WAS CHUGGING, AND ALMOST FELT LIKE THE TRANSMISSION WAS SLIPPING). I PARKED IT. LATER I STARTED IT AND ALL WARNINGS WERE GONE, BUT THE ENGINE LIGHT WAS ON. . THE NEXT DAY I STARTED IT AND JUST THE ENGINE LIGHT WAS ON. 3RD DAY I STARTED IT, ENGINE LIGHT STILL ON. DROVE IT TO A SHOP,.RIGHT BEFORE I PULLED IN, THE LIGHT TURNED OFF! THEY SCANNED IT ANYWAY & SAID THAT NOTHING CAME UP. THE CAR HAS DRIVEN JUST FINE, NO WARNINGS OR LIGHTS UNTIL 11/25/2020. I WAS DRIVING ABOUT 20MPH, TURNED RIGHT ON A SIDE STREET AND ALL OF A SUDDEN ALL OF THE EXACT MESSAGES AS BEFORE CAME ON. VEHICLE IMMEDIATELY STARTED RUNNING SLOW AND "CHUGGING"AGAIN. I PARKED IT. WHEN I STARTED IT AGAIN LATER, ALL THE SAME MESSAGES WERE STILL THERE. IT'S DEFINITELY SCARY WHEN THIS HAPPENS & SINCE THE 1ST TIME IT HAPPENED, I WAS NERVOUS TO DRIVE IT FAR BECAUSE I WASN'T SURE WHEN IT MAY HAPPEN AGAIN. I WENT ON A CHEVROLET FORUM & READ THERE WAS A RECALL FOR THIS ISSUE. I WAS VERY PLEASED ABOUT THAT. I PUT IN MY VIN & IT STATED THAT THERE ARE NO RECALLS. SO I CALLED GM THIS MORNING. THE REP SAID THEY'RE AWARE OF THIS ISSUE, BUT THERE IS NOT A RECALL FOR IT. SHE THEN SAID THAT IT WOULD'VE COVERED BY SPECIAL WARRANTY BUT UNFORTUNATELY THAT WAS UNAVAILABLE AS OF APRIL 2019! HER ADVICE WAS TO TAKE IT TO A CERTIFIED DEALERSHIP AND HAVE IT CHECKED AND FIXED SOON FOR MY SAFETY! I ASKED WHY THERE ISN'T A RECALL, IF IT'S A KNOWN ISSUE AND SHE SAID I COULD TALK TO A CUSTOMER EXPERIENCE MANAGER AT THE DEALERSHIP AND MAYBE THEY COULD DO SOMETHING FOR ME. PLEASE HELP!

THIS IS NOT THE FIRST TIME THIS HAS HAPPENED. ON THE HWY GOING 60MPH, ALL OF A SUDDEN MY ENGINE POWER IS REDUCED AND AIRBAG LIGHT CAME ON. THE NEXT DAY THE AIR BAG LIGHT AND ENGINE LIGHT ARE BOTH ON. WENT TO MY MECHANIC FOR AN INSPECTION (WHICH I FAILED DUE TO THE AIRBAG) AND HE INFORMED ME TO CONTACT THE DEALERSHIP FOR RECALL. I DID, ONLY TO FIND OUT THE RECALL IS CLOSED AND I CAN'T GET THIS FIXED UNLESS I COME UP WITH A LOT OF MONEY. I EXPLAINED I NEVER GOT ANYTHING FROM THE MANUFACTURER ABOUT THE RECALL. HOW CAN I GET MY CAR FIXED ON A CLOSED RECALL?

POWER REDUCES IN HEAVY TRAFFIC. IF I SLOW BECAUSE OF TRAFFIC IT JERKS LIKE BRAKES ARE STILL ENGAGED. ACTS LIKE TRANSMISSION GOING OUT. THIS CAN CAUSE SOMEONE TO GET RUN INTO FROM BEHIND. THERE WAS A RECALL EARLIER THIS YEAR. THE MILEAGE WAS NOT ENOUGH TO COVER MY VECHILE. THERE SHOULD BE NO MILEAGE LIMIT. *TR

WHILE DRIVING, THE CAR IN MOTION IT COMPLETELY LOSES POWER. HAVE EXPERIENCED THIS WHILE ON HIGHWAY, INTERSTATE, AND IN TOWN ROADS. SO PROBLEM OCCURS AT ANY SPEED, AND RESULTS IN VEHICLE COASTING TO A STOP AS THE STEERING AND BRAKES STOP WORKING TOO. HAS HAPPENED TO ME HUNDREDS OF TIMES AS WE CAN NOT PIN POINT PROBLEM, AND HAS REPLACED NUMEROUS DIFFERENT PARTS TRYING TO SOLVE IT. WHEN POWER LOSS OCCURS THERE IS VERY LITTLE TO NO TIME AT ALL FOR DRIVER TO COAST & STEER VEHICLE & OCCUPANTS TO SAFETY AREA ON SIDE OF ROAD. THE DASHBOARD INFORMATION CENTER WILL STATE "STARTING DISABLED, SERVICE THROTTLE" ALSO ENGINE POWER REDUCED" AND "SERVICE STABLITRAK." A NEW THROTTLE HAS BEEN PUT IN VEHICLE AND STILL DOES SAME THING. OVER THE YEAR IVE BEEN DEALING WITH THIS ISSUE IVE NOTICED IT DOES IT MORE IN WARM WEATHER. AFTER VEHICLE COAST TO A STOP AND IS PUT IN PARK AND TURNED OFF, WAIT 5 TO 10 MINUTES THEN VEHICLE WILL START UP AND NO INFORMATION OR LIGHTS DISPLAY IN DASH CENTER, LIKE IT NEVER HAPPENED.

THE SERVICE AIR BAG LIGHT KEEPS COMING ON WHILE WE ARE DRIVING OUR CAR. AND I'M WORRIED THAT THE AIR BAGS WILL NOT DEPLOY IN A ACCIDENT, OR THEY MAY DEPLOY WHILE DRIVING DOWN THE ROAD. I DON'T WANT TO DISABLE THE AIR BAGS BUT NOT KNOWING WHY THE LIGHT FOR THE AIR BAGS IS COMING ON. I HAVE LOOKED ONLINE TO SEE WHAT I CAN DO ABOUT THIS AND I HAVE FOUND OUT THAT THIS IS HAPPENING A LOT ON THE 2006-2014 IMPALA'S. AND PEOPLE HAVE TAKEN THERE CAR IN TO THE DEALERSHIP TO GET FIXED AND THE DEALERSHIP CAN'T FIGURE OUT WHY THIS IS HAPPENING. AND THEY CAN'T SEEM TO FIX IT. PLUS OUR SERVICE OUR TRACTION CONTROL KEEPS COMING ON AND THE DEALERSHIP CAN'T FIGURE OUT WHY THIS IS HAPPENING. THIS SEEMS TO BE THE PROBLEM WITH THIS CAR AND THE DEALERSHIP CAN'T FIGURE OUT WHY THIS IS HAPPENING SO THEY CAN'T FIX IT. SO I'M WORRIED THAT THIS CAR ISN'T SAFE TO DRIVE BECAUSE THE AIR BAGS MIGHT NOT DEPLOY IN A ACCIDENT OR IF THEY WILL JUST DEPLOY DRIVING DOWN THE ROAD.

WHILE DRIVING ON ROADS AND INTERSTATES, I FREQUENTLY RECEIVE A DASH NOTIFICATION "ENGINE POWER REDUCED" AND MY SERVICE TRACTION CONTROL AND CHECK ENGINE LIGHT COMES ON. WHEN THIS HAPPENS, MY VEHICLE LOSES SPEED AND CANNOT ACCELERATE ABOVE 40MPH - DANGEROUS, ESPECIALLY ON AN INTERSTATE. THE NOTIFICATION LIGHTS AND SYMPTOMS OCCASIONALLY GO AWAY AFTER TURNING THE ENGINE OFF AND ON, ONLY TO COME BACK LATER. I CANNOT FIND AND ANSWER TO THIS PROBLEM.

ABS AND TRACTION CONTROL LIGHTS INTERMITTENTLY COME ON CAUSING CAR TO JERK WITH ACCELERATION, OR OCCASIONALLY, TO SLIP DURING BRAKING. WHEEL HUB ASSEMBLIES HAVE BEEN REPLACED MULTIPLE TIMES AND THE SAME FAULTY ISSUE KEEPS REOCCURRING. LOW QUALITY WIRING AND POSITION AND TAUTNESS GOING INTO THE HARNESS ARE A RECIPE FOR DISASTER. SENSORS CAN BE SET OFF WITH AS LITTLE EFFORT AS GENTLY ROCKING THE CAR, DEFINITELY GOING OFF IF THERE ARE ANY BUMPS OR POTHOLES IN THE ROAD. ALSO HAD OTHER ANNOYING ALTHOUGH LESS DANGEROUS ISSUES: DOOR LOCK ACTUATORS AND HEATING/AC ACTUATOR, CAUSING DOOR LOCKS TO NOT RESPOND AND CAUSING A HORRIBLE CLICKING NOISE IN THE CAR, RESPECTIVELY. I HAVE WALKED AWAY FROM THE CAR THINKING I HAD LOCKED IT ONLY TO FIND ONE OR MORE OF THE DOORS DID NOT LOCK. ACTUALLY HAD ITEMS TAKEN FROM THE CAR. THE CLICKING NOISE FROM UNDER THE DASH WAS SPORADIC, USUALLY UPON STARTING THE CAR, BUT OCCASIONALLY WHILE DRIVING WITH NO NOTICE. THIS EAR SPLITTING, HEADACHE INDUCING NOISE WOULD FOR THE MOST PART STOP AFTER SEVERAL MINUTES OF DRIVING, BUT WOULD SOMETIMES CONTINUE AFTER THE CAR WAS SHUT OFF AND WOULD DRAIN THE BATTERY. THE ELECTRICAL SYSTEM THROUGHOUT THE CAR IS HORRIBLE.

THE IMPALA DISPLAYS SERVICE TRACTION CONTROL FOLLOWED BY ENGINE POWER REDUCED. THROWS A CODE FOR THROTTLE BODY SENSOR, BUT THAT DOES NOT FIX THE ISSUE. ACCELERATOR PEDAL POSITION SENSOR IS ANOTHER REASON THEY SAY, WHICH ALSO DOES NOT FIX THE ISSUE. MY CAR HAS SHUT OFF ON ME GOING DOWN THE INTERSTATE, ON A HIGHWAY, AND AND OVER A HILL. IT SHUTS DOWN AND SAYS 'STARTING DISABLED, SERVICE THROTTLE' WITH NO WARNING AT ALL. SEVERAL PEOPLE HAVE HAD THE SAME EXACT PROBLEM AND NO ONE SEEMS TO KNOW HOW TO FIX IT. THEY SAY WIRING BUT IT NEVER FIXED ANYTHING.

LATELY, I HAVE BEEN HAVING ISSUES WITH THE ACCELERATION OF MY VEHICLE. EVERY SO OFTEN, MY ENGINE LIGHT COMES ON AND I GET A "ENGINE REDUCED" NOTIFICATION, AND MY VEHICLE SLOWS DOWN. WHENEVER I REACH 40MPH, MY HP METER DROPS AND MY CAR STARTS SHAKING. THERE HAS EVEN BEEN A TIME WHEN MY CAR WOULD COMPLETELY SHUT OFF AND DISPLAY "IGNITION DISABLED". EACH TIME THIS HAS HAPPENED, THE VEHICLE WAS MOVING ON A HIGHWAY. I WENT TO A SHOP TO GET THE ERROR CODES AND I WILL UPLOAD THEM.

I STARTED MY CAR AND THE CHECK ENGINE LIGHT AND SERVICE TRACTION CONTROL LIGHTS BOTH CAME ON. I GOT ON THE HIGHWAY AND TRIED TO ACCELERATE TO MERGE INTO THE LANE AND MY CAR WOULD NOT ACCELERATE AND THE STEERING WHEEL LOCKED. LUCKILY I WAS ABLE TO GET INTO THE EMERGENCY LANE BEFORE MY CAR SHUT OFF, BUT I WAS VERY CLOSE TO BEING BLASTED BY AN ONCOMING SEMI TRUCK. THIS COULD'VE BEEN FATAL TO ME IF I HAD NOT GOTTEN OVER IN TIME.
