Brake assist, traction control, stablitrack, and ABS lights continually coming on. When breaking while making a turn the breaks slip or give and then suddenly grab hold causing a grinding sound. Car wobbles while these lights are on causing a noticeable change in stability and control.

NHTSA ODI 11423489

WHEN DRIVING THE ABS LIGHT ILLUMINATES, W/ACCOMPANYING MESSAGE: "SERVICE STABILTRAK" FOLLOWED BY 'SERVICE TRACTION CONTROL". CAR GRINDS WHEN TURNING LEFT. TODAY THE GAS PEDAL FELT LIKE IT WAS PUSHING BACK WHEN PRESSED THEN IT FELT LIKE IT LOCKED UP FOR A SECOND.

THE BRAKES ARE AUTOMATICALLY STOPPING WHILE DRIVING ON A CITY STREET. THE TRANSMISSION HAS A PRESSURE VALVE CODE THAT WILL NOT GIVE A DEFINITE READING.THE AIRBAGS LIGHT STAYS ON ALONG WITH THE ABS AND STABILITY TRAK LIGHT STAYING ON.

JANUARY 2019 WAS DRIVING ON A VERY CONGESTED INTERSTATE 95 AT THE POSTED SPEED LIMIT OF 65. A WARNING POPPED UP ON MY DASH BOARD.SERVICE STABIL TRAK ENGINE IN REDUCED POWER. IT WAS LIKE I LONGER CONTROLLED MY CAR. THE SPEED SUDDENLY DROPPED. I WENT FROM 65MPH TO MAYBE 30MPH. IT FELT LIKE MY BRAKES WERE BEING APPLIED . I BECAME SCARED AND ALMOST STARTED TO PANIC. BUT BECAUSE I WAS IN THE FAR RIGHT LANE I WAS ABLE TO PULL OFF THE INTERSTATE. I SAT THERE ON THE SIDE OF THE INTERSTATE WITH MY HEART RACING AND MY HANDS LOCKED ON THE STEERING WHEEL SO HARD THEY CRAMPED UP. I TURNED OFF MY CAR AND REMOVED THE KEYS FROM THE IGNITION. I THANKED GOD I WAS ALONE IN THAT CAR. I THANKED GOD THE CAR BEHIND ME WAS NOT TAILGATING ME. I WAITED FOR ABOUT 5 MINUTES AND THEN PUT THE KEY BACK IN THE IGNITION AND STARTED THE CAR UP. THE WARNING WAS GONE BUT THE SERVICE ENGINE LIGHT REMAINED ON. I WAS SCARED TO DEATH TO MERGE BACK ONTO THE INTERSTATE SO I PUT ON MY FLASHERS AND DROVE ON THE SHOULDER AT 20-30MPH UNTIL I GOT TO THE FIRST EXIT. I MADE IT HOME. I CALLED A CAR REPAIR COMPANY. THEY TOLD ME THE SENSOR MORE THAN LIKELY NEED TO BE RESET. THEY SUGGESTED I TAKE IT TO A CHEVY DEALERSHIP SERVICE CENTER. THE NEXT DAY I STARTED MY CAR UP AND ALL WARNING WERE GONE SO I DID NOT TAKE IT TO THE SERVICE CENTER. THE CAR RAN FINE UNTIL TODAY 52/20/2019. I JUST FILLED MY TANK UP WITH GAS. TURNED IT ON PUT IT IN GEAR AND DROVE 20FEET WHEN THE SAME ERROR CAME ON . I HAD LOOKED UP THIS ERROR ON THE INTERNET. SEEMS LOTS OF AMERICANS HAVE ALMOST BEEN KILLED BECAUSE A CAR MAKER HAS A MECHANISM BUILT IN TO IT VEHICLE THAT TAKES CONTROL OF THE SPEED TO WHICH THE VEHICLE IS TRAVELING. PEOPLE ARE SPENDING A LOT MONEY TO FIX AN ISSUE THAT SEEMS TO NOT HAVE A FIX. CHEVROLET IS PUTTING THE LIVES AND THE LIVES OF OTHERS ON THE ROADS IN JEOPARDY WITH THEIR STABIL TRAK COMPUTER SENSORS.YOUR FAILING AMERICANS

WHILE DRIVING 60 MPH, GO A SERVICE STABILATRAK, REDUCED ENGINE POWER, THEN ENGINE TURNED ITSELF OFF. FORTUNATELY, I WAS ON A STRAIGHT ROAD AS POWER STEERING AND BRAKES DID NOT WORK. AFTER ROLLING TO A STOP, I PUT IT IN PARK AND TRIED TO RESTART. NOTHING! NO CLICKING AT ALL. AFTER 5 MINUTES AND MULTIPLE ATTEMPTS, CAR STARTED AND DROVE NORMALLY??? CAR ONLY HAS 36,000 MILES ON IT.

CAR GETS SERVICE STABITRACK, TRACTION CONTROL AND ABS WARNING ON DASH. REPLACING WHEEL HUBS WITH SENSORS DOES NOT FIX THIS ISSUE. SOMETIMES THE CAR WILL WANT TO APPLY BRAKES WHILE DRIVING OR REDUCE ENGINE SPEED. I HAVE BEEN THROUGH MANY FORUMS WITH PEOPLE REPORTING THE SAME ISSUE ON THE SAME CAR AND THROUGH MULTIPLE YEARS OF MANUFACTURING. FROM THE RESEARCH I HAVE DONE IN THE LAST FEW DAYS IT LOOKS LIKE HUNDREDS OF OWNERS HAVE REPORTED THIS ISSUE BUT CHEVROLET IS NOT DOING ANYTHING TO CORRECT IT. NOT SURE AT THIS POINT IF IT IS THE WIRING HARNESS CAUSING THE PROBLEM OR IF THIS COULD BE SOMETHING WITH THE COMPUTER THAT CONTROLS THE STABITRACK, ABS AND TRACTION CONTROL. IF CARS ARE LOOSING POWER AND OR THE BRAKES ARE BEING APPLIED WITH OUT DRIVER CONTROL THIS CAN LEAD TO DANGEROUS DRIVING CONDITIONS FOR THE CAR OWNER PASSENGERS AND EVERYONE ELSE DRIVING ON THE SAME ROAD. WITH HOW MANY PEOPLE ARE REPORTING THIS I DO NOT SEE WHY THE CAR OWNER SHOULD NEED TO PAY THOUSANDS OF DOLLARS TO DIAGNOSE AND MAYBE FIX THE ISSUE. FROM WHAT I HAVE READ SOME PEOPLE HAVE HAD TO PAY FOR MULTIPLE SERVICE EVENTS AND THE ISSUE STILL NOT RESOLVED.

WHEN COMING TO A STOP MY ABS SERVICE STABILITY TRACTION CONTROL SERVICE BRAKE LIGHTS ALL COME ON THEN MY 2011 HESITATION TO STOP WHEN BRAKING. EVEN IF I GO SLOW OR JUST STOPPING AT A STOP SIGN. IT PUSHES MY FOOT FROM THE BRAKE. A CRANKING NOISE SOUND. I HAVE GOTTEN BRAKE, TIRE RODS, ROADERS AND NEW TIRES. I DON'T KNOW WHAT ELSE TO DO. THIS HAPPENS SPECIFICALLY WHEN ON THE HIGHWAY WHEN HAVING TO COME TO A SUDDEN STOP. I ALMOST CRASHED SEVERAL TIMES NOT BEING ABLE TO STOP. MIND YOU MY CAR ONLY HAS 65000 MILES ON IT. THIS IS JUST TOO SOON.

NHTSA ODI 11089813

WHEN TAKING LEFT TURNS THE CAR MAKES A LOUD GRIND NOISE THEN THE STABILITY CONTROLL WILL TURN ON. NOW THE CHECK ENGINE LIGHT AND STABILITY CONTROLL LIGHT POPPED ON WHILE DRIVING WHILE ALSO HAVING ENGINE POWER REDUCED WHICH THEN APPLIED MY BRAKES CAUSING ME TO ALMOST GO OFF THE ROAD.

NHTSA ODI 11056328

I CONTINUE TO HAVE PROBLEMS WITH MY FRONT LEFT HUB AFTER REPLACING. I HAVE REPLACED THE WIRING HARNESS AS WELL. WONDERED IF THERE ARE SERVICE BULLETINS WITH THIS SAME ISSUE. WHILE DRIVING THE CAR IT MAKES A HORRIBLE GRINDING NOISE DESCRIBED TO ME AS THE HUB ADJUSTING THE SPEED OF ONE TIRE TO MATCH THE OTHER. IT ALSO FLASHES BRAKE ASSIST AND STABILITRACK ISSUES AS WELL AS ANTI LOCK ALERT. THIS HAPPENS MOSTLY TURNING LEFT BUT MOST RECENTLY EVEN WHILE DRIVING STRAIGHT DOWN THE ROAD.

MY SERVICE STABILITRACK, REDUCE ENGINE POWER LIGHT CAME ON WHILE I WAS EXITING THE FREEWAY. WHEN THIS HAPPENED I HAD ALMOST NO BRAKE PEDAL. I COULDN'T STOP AT THE LIGHT AT THE END OF THE EXIT, LUCKILY NO OTHER CARS WERE AROUND. IF I HAD BEEN ON A MAIN STREET AT 45MPR AND HAD TO STOP FOR A RED LIGHT I WOULD HAVE NEVER STOPPED ON TIME. I'M VERY LUCKY NO CARS WERE AT THE LIGHT WAITING OR COMING IN A DIFFERENT DIRECTION WITH THE GREEN LIGHT. I SEE THIS PROBLEM ALL OVER EDMUNDS AND ON YOU TUBE AND AS FAR AS I CAN TELL IT'S 100% CHEVROLET. HOW CAN THIS NOT BE A RECALL. THERE ARE DOZENS AND DOZENS OF THE SAME COMPLAINT ON EDMUNDS AND YOU TUBE. IT SEEMS LIKE EVERY YOU TUBE VIDEO HAS A DIFFERENT FIX FOR THE PROBLEM....FROM PULLING OUT THE FUSE TO THE STABILITRACK TO OVER A THOUSAND DOLLARS IN REPAIRS. DOES THERE HAVE TO BE A DEATH TO GET THE ATTENTION OF CHEVROLET. THE LIGHT HAD COME ON A FEW TIMES BEFORE BUT THIS WAS THE FIRST TIME IT HAPPENED WHILE I WAS DRIVING. USUALLY IT CAME ON AND I WOULD TURN THE CAR OFF FOR A FEW MINUTES AND IT WOULD BE FINE......SO HOW COULD THIS BE ANYTHING BUT A MALFUNCTION IF IT GOES OFF AND ON AT ANY WHIM. THEY MUST KNOW ABOUT THIS PROBLEM AS IT SEEMS TO BE VERY PREVALENT AND AGAIN FROM WHAT I HAVE READ IT'S ALWAYS A CHEVROLET.

MY WIFE WAS DRIVING HOME FROM WORK GOING 65 DOWN A VERY BUSY HIGHWAY. ALL OF A SUDDEN THE REDUCED ENGINE POWER LIGHT, CHECK ENGINE, STABILITY CONTROL OFF, AND TRACTION CONTROL LIGHTS CAME ON. THE CAR BEGIN TO LOOSE SPEED. LUCKILY SHE WAS ABLE TO GET OVER TO THE RIGHT SHOULDER WITHOUT ANYONE HITTING HER. WHEN SHE GOT TO THE SHOULDER THE CAR WAS RUNNING REALLY ROUGH. SHE TURNED IT OFF WAITED A FEW MINUTES AND RESTARTED IT. IT THEN RAN FINE BUT THE CHECK ENGINE LIGHT REMAINED ON. SHE MADE IT HOME AND WAS SCARED TO DRIVE IT AGAIN. I TOOK IT TO WORK LAST NIGHT AND MADE IT ABOUT HALFWAY TO WORK AND IT DID THE EXACT SAME THING EXCEPT I WAS ABLE TO GET IT TO MAINTAIN 45MPH. WHEN I CAME TO A TRAFFIC LIGHT THOUGH THE ENGINE WAS RUNNING SO ROUGH THE CAR WAS VERY HARD TO STOP. I MADE IT TO WORK. WHEN I CAME OUT TO GO HOME THE FIRST STOP LIGHT I CAME TO IT STARTED ACTING UP AGAIN. FROM THE LIGHT I WAS BARELY ABLE TO GET IT TO GO 25MPH. I PULLED OVER AND SHUT THE CAR OFF WAITED A FEW MINUTES AND RESTARTED. EVERYTHING WAS FINE AGAIN. I MADE IT ABOUT 5 MILES AND ALL THE LIGHTS CAME ON AGAIN BUT I WAS ABLE TO MAINTAIN 45MPH IN THE 55MPH ZONE I WAS IN. I TOOK IT TO MY REPAIR SHOP AND THEY SAID IT NEEDS A THROTTLE BODY. THEY ALSO SAID GM HAS HAD ALLOT OF ISSUES WITH THESE. I CALLED MY GM DEALER TO SEE IF IT WOULD BE COVERED UNDER 5 YEAR 100K MILE WARRANTY AND THEY SAID THAT IT ISN'T. IF THERE HASN'T BEEN AN ACCIDENT CAUSED BY ONE OF THESE THROTTLE BODY ISSUES YET I WOULD BE SURPRISED. IT'S VERY DANGEROUS IN HEAVY TRAFFIC AND ALL OF A SUDDEN YOU CAN'T GO. *TR

2/17/2015 WAS THE SECOND EVENT. I WAS DRIVING APPROX- 65 MPH UP A MOUNTAIN WHEN MY ELECTRONIC DISPLAY PANEL SHOWED STABILITRACK/SERVICE TRACTION CONTROL/VEHICLE IN REDUCED POWER. AS THE POWER SUDDENLY REDUCED I LOST POWER STEERING CONTROL AND BRAKE FUNCTION. SINCE I WAS TRAVELING AT A UP HILL GRADE, I WAS BARELY ABLE TO JERK THE STEERING WHEEL ENOUGH TO ROLL ACROSS THE LANE OF TRAFFIC BESIDE ME TO THE SIDE OF THE ROAD. I WASN'T ABLE TO GET OUT OF THE ROAD COMPLETELY AND WAS ALMOST HIT BY A LOGGING TRUCK. AFTER REMOVING THE KEYS FROM THE IGNITION FOR A FEW MINUTES, I RESTARTED THE CAR WITHOUT ANY HESITATION. THE ENGINE LIGHT STILL REMAINS ON AT THIS TIME. I DID CONTACT ONSTAR AND HAVE THEM RUN A DIAGNOSTIC TEST WHICH REVEALED A PROBLEM WITH SUPPOSED FUEL SYSTEM. I HAVE NOT TAKEN IT TO A DEALERSHIP YET. AFTER SO MANY COMPLAINTS ON VARIOUS SITES THAT I HAVE REVIEWED, LOOKS LIKE GM WOULD DO A RECALL AND INVESTIGATE THE PROBLEM BEFORE SOMEONE LOSES THEIR LIFE. *TR
