2010 CHEVROLET IMPALA Vehicle Speed Control Problems

I bought a used car as is for $6700.00 and was told that the car was nothing wrong with it but within the first month 07/02/25 the car has been to 3 different shops and in the shop 5 different times all due to brake problems since I bought the car I have had to replace both front calipers and rotors brake pads wheel bearings and on the back both brake pads plus new tires and it's still not fixed the ABS traction and stability lights are on i could of caused a wreck I only drive it to the store with the money I had paid for the car putting it in a shop I shouldn't of had to do they sold me a dangerous car

I started my vehicle in the morning to let it warm up. I come back out to get myself and my son in the vehicle to go to work and take him to school. My dash upon entry had a check engine light on, and the message it displayed was "engine power reduced." I put my car into reverse, having no choice but to drive it and the traction control went out. My father in law pulled the code and it said something about the accelerator sensor. This is a known issue and recall in other models and I wanted to report it is also happening in my model.

Service stabilitrak message displayed and reduced engine power to 0 mph while driving. Throttle body, Accelerator pedal position sensor (whole pedal assembly), and ecm replaced. Issue continues. P2138, P2122, P2127 codes present. Stonebriar chevrolet incompetent to resolve.

THE TRANSMISSION GO OUT AT ANY TIME WHILE YOU'RE DRIVING IT'LL JUST STOPPED IN THE MIDDLE OF TRAFFIC WHICH CAN CAUSE AN ACCIDENT THE COMPANY CHEVROLET NEW THAT THEY PUT BAD TRANSMISSION IN THOSE CARS AND LIGHTS BLINK ON AND OFF. ELECTRICAL ISSUE THE SPEEDOMETER AND THE GAS METER IN MOVES BY ITSELF WHEN THE CAR IS OFF AND WHEN YOU ARE DRIVING THE CAR IT'LL MOVE BY ITSELF DISPLAYING ACCURATE INFORMATION AND THAT'S VERY DANGEROUS I WAS ON THE HIGHWAY IN THE TRANSMISSION JUST WENT OUT IN CARS ALMOST RAN INTO ME I LIKE TO BUY THAT DAY BECAUSE OF THE TRANSMISSION EVERYBODY I KNOW WITH THIS CAR HAS THE SAME ISSUE SOMETHING REALLY NEEDS TO BE DONE ABOUT IT BEFORE SOMEONE DIES

THE TRACTION CONTROL LIGHT AND THE ABS LIGHT CAME ON AT THE SAME TIME AND ITS SAYING SERVICE TRACTIONCONTROL SYSTEM/SERVICE STABILATRAK SYSTEM AND ALSO SERVICE ASSITED BRAKE CONTROL SYSTEM I DID SOME RESEARCH AND I FOUND OUT THIS IS A COMMON PROBLEM WITH THESE CARS AND SHOULD BE ADDRESSED BY GM TO BE FIXED AT THEIR COST NOT MINE

DRIVING HOME ONE NIGHT AFTER JUST HAVING MY VEHICLE REPAIRED A FEW WEEKS EARLIER, WITHOUT WARNING, MY VEHICLE BEGAN TO STALL. JUST BEFORE THE STALL IT WAS DRIVING COMPLETELY NORMAL WITH NO ISSUES AT ALL. SUDDENLY THE CHECK ENGINE LIGHT CAME ON ALONG WITH THE MESSAGES OF SERVICE STABILTRACK, TRACTION CONTROL DISABLED, AND LOW ENGINE POWER. WHEN I TOOK THE VEHICLE TO THE DEALER I BOUGHT IT FROM I WAS TOLD THAT THERE WAS AN AFTERMARKET SENONDARY AIR CHECK VALVE THAT WAS CAUSING THE ISSUE. WITH THIS THEY GAVE ME THE FOLLOWING CODES; P0068, P0340, P0651, AND P2135. DUE TO ME JUST RECENTLY GETTING THIS PART REPLACED THIS PAST FEBRUARY I TOOK IT BACK TO THE MECHANIC THAT REPLACED IT. WHEN I RECEIVED THE VEHICLE BACK IT WOULD NO LONGER EVEN START. THE MECHANIC THEN INFORMED ME THAT THE AIR VALVE WOULD NOT CAUSE THIS ISSUE AND THERE WAS SOMETHING ELSE WRONG WITH THE VEHICLE AND TO TAKE IT TO ANOTHER DEALER. WHEN THAT WAS DONE I WAS TOLD A SECOND TIME THAT IT WAS THE AIR VALVE. I HAVE NOW COME OUT OF POCKET TWICE FOR TOWS THAT I CAN'T AFFORD. ALONG WITH PAYING FOR AN EXPENSIVE PART POSSIBLY TWICE. VEHICLE ONLY HAS 50K MILES ON IT AND HAS NEVER GIVEN ME ANY ISSUES UNTIL THIS YEAR.

ON OR ABOUT MAY 17, 2015, I RECEIVED NOTICE FROM THE CHEVROLET DIVISION OF GENERAL MOTORS THAT MY VEHICLE "MAY HAVE A BROKEN SOLDER CONNECTION WITHIN THE ACCELERATOR PEDAL POSITION (APP) SENSOR. THIS CONDITION MAY RESULT IN REDUCED ENGINE POWER AND LOSS OF TRACTION CONTROL ASSIST." ACCORDING TO THEM, I WILL KNOW WHEN MY INFORMATION CENTER DISPLAYS THE WARNING AND THEN THEY WILL BE WILLING TO CORRECT THEIR POOR WORKMANSHIP, BUT NOT UNTIL THAT TIME. GM GOES ON TO INFORM ME THAT I MAY BE WITHOUT MY CAR FOR AN EXTENDED LENGTH OF TIME WHILE THEY ORDER PARTS AND DO REPAIRS. I DON'T SEE WHY I SHOULD BE THE ONE WHO WILL BE INCONVENIENCED FOR THEIR LACK OF PROPER WORKMANSHIP. FURTHERMORE, I FEEL THERE IS A SAFETY ISSUE HERE ALSO.

WHILE DRIVING NORTHBOUND ON I-75 IN SOUTHERN KY, THE CAR SUDDENLY LURCHED A LITTLE AND "TRACTION CONTROL" AND "STABILIZATION" ERRORS DISPLAYED FOLLOWED BY "REDUCING POWER." AND, THE CHECK ENGINE LIGHT CAME ON. I CALLED MY CHEVY DEALER AND ASKED IF IT WAS SAFE TO CONTINUE DRIVING - THEY SAID YES, AS LONG AS THE CHECK ENGINE LIGHT WASN'T FLASHING. WE WENT ABOUT 5 - 10 MORE MILES AND THE DISPLAY FLASHED SOMETHING ABOUT THROTTLE PROBLEM AND THEN "SHUTTING DOWN ENGINE", WHICH IT DID IMMEDIATELY WITH NO WARNING WHILE WE WERE DOING ABOUT 70 - 75MPH IN THE MIDDLE OF THE 3 NORTHBOUND LANES OF I-75. I HAD TO TRY TO STEER TO THE SHOULDER WITH NO POWER STEERING OR BRAKES. ONCE THERE, I TRIED TO RESTART THE CAR AND NOTHING HAPPENED - IT DISPLAYED "STARTER DISABLED." WE CALLED OUR ROAD SERVICE AND THEY TOOK OUR INFO, FOUND THE NEAREST CHEVY DEALER WHO SAID THEY COULD WORK ON IT ASAP IF WE GOT IT IN THERE. WHILE THEY WERE WORKING ON SETTING UP A TOW I TRIED STARTING IT AGAIN. IT STARTED BUT THE CHECK ENGINE WAS STILL ON. I TRIED DRIVING A LITTLE ALONG THE SHOULDER AND IT SEEMED OK SO I SAID WE'D TRY DRIVING TO THE DEALER RATHER THAN WAIT FOR A TOW TRUCK. WE MADE IT. THEY GOT ON IT FAIRLY QUICKLY AND FOUND THE PROBLEM WAS THE GAS PEDAL POSITION SENSOR. WE WERE FORTUNATE THAT THE TRAFFIC WAS LIGHT AND I COULD SAFELY PULL OFF. I HATE TO THINK WHAT THE RESULTS WOULD HAVE BEEN IF THIS HAD HAPPENED EARLIER AS WE WERE TRAVELING THRU ATLANTA WITH ITS 6 LANES OF HEAVY TRAFFIC. SUDDENLY LOSING POWER AND CONTROL IN THAT TRAFFIC WOULD PROBABLY HAVE CAUSED ONE OF THOSE MULTI-VEHICLE ACCIDENTS THAT MAKE THE NATIONAL NEWS. WHAT KIND OF INCOMPETENT PROGRAMMING OF THE CAR'S COMPUTER WOULD TRIGGER A FULL, INSTANT SHUTDOWN BECAUSE OF A FAULTY ACCELERATOR PEDAL POSITION SENSOR? I WOULD SUGGEST AN IMMEDIATE RECALL TO RE-FLASH THE COMPUTER TO ELIMINATE THE NO-WARNING SHUT DOWN. *TR

EARLIER WHEN I TRIED TO START IT ACTED AS THOUGH THE BATTERY WAS DEAD. THIS TIME IT STARTED AND I DROVE IT HOME .A LOCAL REPAIR SHOP REPLACED THE GAS PEDAL .I HAD BOUGHT THIS CAR NEW AND IT HAS NEVER BEEN IN A CRASH OR HAD ANY REPAIRS DONE BESIDES ROUTINE SERVICE. NO ONE WAS HURT BUT THIS CAR SHOULD NOT HAVE SHUT OFF AT 70 MPH BECAUSE OF A DEFECTIVE SENSOR ON A GAS PEDAL.I AM A RETIRED STATE TROOPER AND I AM SURE MY TRAINING SAVED ME FROM BEING IN AN ACCIDENT YESTERDAY BECAUSE I HAPPENED TO HAVE OTHER CARS AND SEMI S DRIVING NEAR ME. *TR

HIGHWAY DRIVING THIS PROBLEM COULD CAUSE AN ACCIDENT .I CAN SEE THIS HAS BEEN A ISSUE WITH GENERAL MOTORS WITH IMPALAS AND OTHER MODELS SINCE 2008.HOW MANY OF THE SAME COMPLAINTS WOULD IT TAKE UNTIL ITS FIXED .COMPLAINTS KEEP COMING UP AFTER THROTTLE BODIES REPLACED STILL HAVING SAME PROBLEMS. GENERAL MOTORS NEEDS TO GET WITH THE PROGRAM. *TR

ANY OTHER CAR THAT I HAD HAVE IN THE PAST I MADE SUDDEN STOPS AND CHECK ENGINE LIGHTS NEVER COMES ON. WHATS GOING ON WITH THE CHEVROLET IMPALAS? THEY LOOK NICE BUT THEY ARE SSSOOOO NOT WORTH THE COST TO PURCHASE OR TO GET REPAIRED. THIS IS THE ONLY BAD INVESTMENT I HAVE EVER MADE IN MY LIFE. I SHOULD HAVE STUCK WITH MY MAZDA. I WILL LET IT BE KNOWN TO ANYONE WHO ASK ME ABOUT CHEVROLET TO DONT EVEN BOTHERED. THERE ARE BETTER CARS THAN THE CHEVROLET. THIS CAR IS ALSO A GAS GUZZLER. I PUT $50 IN THE TANK EVERY 5 DAYS WHEN DRIVING LOCALLY. I ONLY WORK 10 MINUTES FROM MY HOUSE. EVERYTIME YOU STOP YOU LOOSE GAS MILEAGE ON YOUR DIC THE GAS IS GREAT ON THE HIGHWAY THOUGH. LIKE I SAID THE WORST INVESTMENT I HAVE EVER MADE. CHEVROLET....IM SO UPSET AND DISAPPOINTED. *TR

DRIVING HOME FRIDAY NIGHT 12/26/12 ON CRUISE SET AT 65, BANG, CAR DROPPED POWER DRASTICALLY, KICKED OFF CRUISE, AND THE THREE ROTATING MESSAGES APPEARED ON DASH, 1)SERVICE STABILITRAK, 2)SERVICE TRACTION CONTROL, & 3)ENGINE POWER REDUCED. BOTH ORANGE PLACARDS LIT UP ON DASH, SERVICE ENGINE AND TRACTION. PULLED OUT OF TRAFFIC AND RE STARTED THE CAR. WAS ABLE TO DRIVE AT NORMAL SPEEDS BUT CODES STILL ROTATING AND PLACARDS STILL LIT. COULDN'T GET IT INTO THE SHOP UNTIL MONDAY 12/31/12. WHEN I STARTED IT UP TO TAKE IT IN, CODES WERE ALL CLEARED AND CAR RAN JUST FINE. DEALERSHIP TOLD ME IT WAS THE PEDAL SENSOR AND WOULD COST ME $275 TO REPAIR. HOW CAN WE GET GM TO DO A RECALL ON THIS ON GOING ISSUE? THIS IS A 2010 CHEVY IMPALA LT WITH 45000 ON IT. THIS REPAIR SHOULD BE COVERED UNDER WARRANTY AND I WAS TOLD IT IS NOT. THERE HAVE BEEN NUMEROUS INDIVIDUALS WITH THIS SAME SENSOR FAILING AT ABOUT 45000 MILES. A SUDDEN DROP IN POWER TO A SPEED OF 25 WHILE DRIVING AT HIGHWAY SPEEDS IS VERY DANGEROUS. IT IS AMAZING WITH AS MANY FAILURES AS HAVE BEEN REPORTED TO GM ON JUST THE EDMUNDS CAR FORM SITE ALONE THAT THERE HAVE NOT BEEN ANY SERIOUS CRASHES. PLEASE TAKE A GOOD LOOK AT THIS ISSUE AND SEE IF YOU CAN'T GET GM TO RECALL THESE SENSORS AND GET THEM REPLACED WITH BETTER ONES. *TR
