2012 Chevrolet Impala

TRACTION CONTROL AND STABLITRAK LIGHTS COME ON. GRINDING SOUND AND HESITATION BEFORE MOVING IN REVERSE, GOING STRAIGHT AND TURNING. THE HESTIATION KEEPS THE CAR FROM MOVING. CAN TURN OFF AND FIX THIS ISSUE FOR A SHORT BIT OF TIME WITH THE BOTTOM ON THE DASH. AFTER A WHILE TURNING IT OFF DOESN'T HELP BECAUSE IT TURNS ITSELF BACK ON.

I HAVE A 2012 CHEVY IMPALA, THE TRACTION SERVICE CONTROL AND ABS/STABILITRACK KEEPS GIVING ME ISSUES. I HAVE A GRINDING NOISE, DECREASED POWER AND CAR WILL NEARLY STOP ON YOU FROM TIME TO TIME, PARTICULARLY WHEN TURNING. TAKEN TO DEALERSHIP, MORE THAN ONE, THEY KEEP TELLING ME THE HARNESS ATTACH TO MY TRACTION CONTROL SYSTEM SNAPS. IVE HEARD MY MODEL HAS THIS ISSUE. I SEE NO RECALL FOR MY VIN, BUT I HAVE THE SAME ISSUES.

CLUNKING , GRINDING NOISE SERVICE STABILITRAK, SERVICE ABS LIGHTS COME ON LOSE POWER WHEN REVERSING OR MAKING A LEFT TURN. AFTER MUCH RESEARCH THERE SEEMS TO BE A PROBLEM WITH THE WIRING HARNESS GOING TO THE SENSORS IN THE WHEELS. MANY PEOPLE ARE HAVING THIS VERY SAME PROBLEM ACROSS MANY YEARS OF THIS VEHICLE. PEOPLE ARE SPENDING MONEY UNNECESSARILY ON PARTS SUCH AS WHEEL HUBS AND BEARINGS WITHOUT FIXING SAID PROBLEM. MANY PEOPLE ARE ALSO REPORTING CARS TURNING OFF AS A RESULT OF THIS. *TR

1ST - 8/11/2018 - 79,653 MILES - CHECK ENGINE LIGHT CAME ON, CODE P0411 SECONDARY AIR INJECTION SYSTEM INCORRECT FLOW DETECTED. DEALERSHIP STATED THE SOLENOID MALFUNCTION CHECK ENGINE CAME BACK ON, CODE P0411, CHEVROLET STATED THE SECONDARY AIR INJECTION SYSTEM IS FUNCTIONING AS DESIGNED AND RESET THE CODE. CHEVY'S STATED THE FAULTY SIR INJECTION SOLENOIDS BANK 1 AND 2 WAS THE CAUSE OF THE CHECK ENGINE LIGHT CODE P0411. ADVISED ME THAT THE BATTERY TERMINAL MAY BE THE ISSUE AND RECOMMENDED CHANGING IT. RECOMMEND A NEW ALTERNATOR. CHEVY WAS UNABLE TO VERIFY THE CODE P0411 BUT MADE A RECOMMENDATION FOR THE ISSUE. CHECK ENGINE LIGHT CAME BACK ON AGAIN, NO OTHER ISSUES WITH THE VEHICLE AT THAT TIME. GM OPENED A TAC CASE. ADVISED BY TAC THAT CARBON BUILDUP IN THE CYLINDER VALVES FROM THE CYLINDER HEADS WAS THE CAUSE. TOLD TO DRIVE VEHICLE FOR A FEW DAYS. WITHIN 3 DAYS CHECK ENGINE LIGHT CAME BACK ON. CHEVY INSTALLED A VEHICLE DATA RECORDER PER THE GM FIELD SERVICE ENGINEER. TEST RESULTS SHOWED BOTH AIR INJECTION CUT OF VALVES NEEDED TO BE REPLACED. FUTURE ALSO UPDATED ECM CALIBRATION AND PROGRAMMED IT - COVERED UNDER WARRANTY. 6TH VISIT ON 9/3/2019 AT 85970 MILES CHEVROLET ADVISED THE CAUSE IS DUE TO THE LEFT TEMPERATURE CONTROL AND AIR INLET ACTUATORS. 7TH - 9TH TIME, ADVISED BY INDEPENDENT AUTO REPAIR SHOP, THAT EVERYTHING WAS WORKING AS NORMAL. CHECK ENGINE LIGHT CODE WAS RESET. ADVISED CAR NEEDS TO BE CALIBRATED AT GM-APPROVED DEALERSHIP. AS OF TODAY, THE CHECK ENGINE LIGHT REMAINS ON. THE FINAL SHOP ADVISED THE ISSUE MAY BE THAT THE SYSTEM WAS NOT CALIBRATED OR JUST NEEDED TO BE CALIBRATED EVERY TIME THE CHECK ENGINE LIGHT CAME ON. I BELIEVE THAT THOUSANDS OF GM CUSTOMERS ARE PAYING OUT OF POCKET FOR UNNECESSARY P0411 REPAIR WORK.*DT*JB

WHILE DRIVING HOME FROM WORK DURING RUSH HOURS MY 2012 CHEVY IMPALA'S DASHBOARD LIGHTS UP SAYING " SERVICE TRACTION CONTROL, SERVICE STABILINK, ENGINE POWER REDUCED" TERRIFIED AS I WAS IN THE MIDDLE LANE TRYING TO GET OVER AS MY CAR BEGAN TO GO INTO LIMP MODE.I ALMOST GOT REAR ENDED DUE TO THIS PROBLEM. I WAS ACCELERATING FROM BEING STOPPED.

THE FRONT HUB ASSEMBLY IS CONTINUOUSLY DEFECTING. INHAVE REPLACED BOTH SIDES A MINIMUM OF 6 TIMES SINCE 2013. THE STEERING GOES OUT, THE BRAKES GRIND THE TRACTION CONTROL INITIATES AND IN SEVERE TIMES I LOOSE ALL POWER TO VEHICLE. THIS IS IN MOTION. FROM COMPLETE STOP TO MOTION, WHILE IN REVERSE AND WHILE TURNING IN IETHER DIRECTION.

WHILE DRIVING 30 MPH ON CITY STREETS GOING STRAIGHT WITH A SLIGHT INCLINE THE A/C AND RADIO POWERED ON AND OFF SEVERAL TIMES. WHEN STOPPED AT A STOP LIGHT THE DOORS UNLOCKED AND "SERVICE STABILITRAK" FLASHED ON AND OFF THE DASH, THE RADIO POWERED DOWN, AND THE A/C TURNED OFF. AFTER A FEW SECOND EVERYTHING WENT BACK TO NORMAL. NO CHECK ENGINE LIGHTS CAME ON AT ALL. THIS IS NOT THE FIRST TIME THIS HAS HAPPENED.

SINCE 2017, UPON STARTING MY CAR I GET ALL OF THE FOLLOWING ALERT MSGS "SERVICE STABILITRAK", *SERVICE BRAKE ASSIST" AND "SERVICE TRACTION CONTROL" ON MY DASHBOARD. I'VE HAD THE CAR INTO LES SCHWAB AND ERROR CODE DIAGNOSTICS DONE BOTH BEFORE AND AFTER BOTH FRONT HUB ASSEMBLIES WERE REPLACED. THE SAME SERVICE MESSAGES STILL CONTINUE TO APPEAR ON THE DASH. LES SCHWAB HAS CHECKED THE HUB SENSOR WIRES REPEATEDLY AND ALL ERROR CODES AND FIND THEM TO BE OK. THEY FIND THE CAR TO STILL HAVE A CRUNCHING NOISE COMING FROM THE FRONT END OF THE CAR, MOST MARKEDLY WHEN TURNING THE WHEEL TO THE LEFT, BUT CAN ALSO BE HEARD WHEN THERE IS A DROP IN ELEVATION, AS WHEN EXISTING A PARKING LOT INTO A SLIGHTLY LOWER ROADWAY. ON JUNE 14,2019, WHILE THE CAR WAS IN MOTION AND TURNING RIGHT AT A STOPLIGHT, THE SAME SITUATION OCCURRED AS HAS WHEN I MAKE A LEFT TURN. THE CAR SUDDENLY ACTED AS THOUGH THE BRAKES WERE BEING APPLIED VERY HARD AND THEN THE CAR HALTED BRIEFLY WITH TRAFFIC BEHIND ME AS THOUGH IT WOULD STALL OUT. I APPLIED THE ACCELERATOR TILL I FORCED THE CAR TO MOVE AROUND THE CORNER AND AFTER ABOUT A MINUTE OF FIGHTING BRAKING RESISTANCE, I WAS ABLE TO REGAIN NORMAL 40 MPH SPEED WITH THE FLOW OF TRAFFIC. THIS OCCURRED ON DRY PAVEMENT WITH NO PRECIPITATION. OUTSIDE TEMPERATURE WAS AROUND 100 DEGREES. BEST DRIVING CONDITIONS WITH NO ROUGH ROADWAY. LES SCHWAB SAID THE PROBLEM WITH THE HUB SENSOR AND LEFT TURNING IS A KNOWN PROBLEM TO THEM AND SAID THEY WISH IT WOULD BE MADE A RECALL ITEM AS IT IS A COMMON PROBLEM NOW. I DON'T FEEL SAFE DRIVING THIS CHEVY IMPALA. LOVE MY CAR BUT WON'T TAKE A CHANCE ON PURCHASING SAME MAKE AND MODEL. I WASN'T SO SURPRISED WHEN RESEARCHING THESE ISSUES ON THE INTERNET TO FIND HUGE NUMBER OF OWNER'S HAVING THE SAME PROBLEMS.
