2013 CHEVROLET IMPALA Power Train Problems

While driving vehicle warning light service stabilitrak....reduced engine power comes on. Vehicle then slows and can not drive over 20 to 30 mph. This has occurred randomly at highway speeds while driving on interstate in traffic. Sudden reduction caused traffic to have to slow quickly and almost caused a collision.

TFP Switch(Sensor) 4 Circuit Low Voltage

while waiting to make a left turn when traffic cleared I pressed the gas pedal and heard a loud grinding noise and the car would not move for 2 or 3 seconds and suddenly moved. Very dangerous. Car forums have many of the same incidents with great difficulty in resolving this problem and after several years no answers. This is life threatening issue.

The contact owns a 2013 Chevrolet Impala. The contact stated that her vehicle would fail to start up after multiple attempts without warning. The contact stated that while her fiance was driving at 55 MPH, the vehicle shut off without warning which cause him to crash into a ravine. The air bags did not deploy upon impact. The contact and her fiance suffered minor scrapes and bruises but did not seek medical attention. A police report was filed at the scene. The vehicle was towed to an independent tow yard where it was deemed a total loss. The dealer was contacted about the incident and was informed that they could not pick up the vehicle to perform an investigation. The manufacturer had yet to be notified of the failure. The vehicle was destroyed. The failure mileage was unknown

ABLE TO SHIFT GEAR POSITIONS BUT THE INDICATED SHIFT POSITION DOES NOT REPRESENT THE GEAR POSITION THE VEHICLE IS IN. WHEN I STOP AND PARK THE VEHICLE, I AM ABLE TO SHIFT THE LEVER TO THE "PARK" POSITION, BUT THE VEHICLE IS NOT ACTUALLY IN PARK POSITION. I CURRENTLY HAVE THE EMERGENCY BREAK ON. VEHICLE WILL NOT STAY IN PARK WHEN GEAR IS IN PARK POSITION. THE LIGHTEST TOUCH WILL KNOCK GEAR SHIFT INTO REVERSE AND CAR ROLLS AWAY.

I DONT UNDERSTAND WHY MY CAR SHOWS NO MISFIRES UNTIL TODAY AND ITS THE FUEL CONTROL MODULE BUT IT RESETS AND GOES AWAY THEN BACK AGAIN LIKE ITS REMOTE CONTROL. WHILE STATIONARY BATTERY IS FAIR/ ALTERNATOR FAIR

DOES NOT SHIFT INTO GEAR SMOOTHLY. I CAN FEEL A JERK WHEN TRANSMISSION CHANGES GEARS. THERE IS A DELAYED RESPONSE WHEN WHEN EXCELERATING FROM A STANDSTILL. THIS VEHICLE HAD 36000 MILES WHEN WE NOTICED THE PROBLEM 4 MONTHS AGO. PROBLEM CODE P0989 SHOWN WHEN RECENTLY CHECKED BY MECHANIC. ANOTHER PROBLEM IVOLVES AN INTERMITTENT METALLIC GRINDING NOISE WHEN MAKING A LEFT TURN AT LOW SPEEDS.

SERVICE STABILITRACK WARNING INDICATOR LIGHTS FLASH AND BEEP WHILE ALL GUAGES GO TO ZERO AND BACK WHILE DOOR LOCKS ARE ALSO ENGAGING OPEN AND CLOSED AT ALL SPEEDS. HAS BEEN ALMOST ON DAILY BASIS FOR THE LAST FEW MONTHS. BEFORE 6 MONTHS AGO WOULD ONLY HAPPEN OCCASIONALLY.VEHICLE WILL LOSE ACCELERATION FOR A FEW SECONDS. . THIS WILL HAPPEN SEVERAL TIMES WHILE DRIVING CONSECUTIVE ALMOST 10-20 TIMES IN A ROW. TRACTION CONTROL AND ABS, BRAKE ASSIST WILL ALSO HAVE WARNING LIGHTS GO OFF. HAVE HAD MY CAR IN 2 DIFFRENT SHOPS AND SPENT ALMOST $2000 AND STILL NO FIX. . CHEVY NEEDS TO DO A BETTER JOB EXPLAINING WHAT SERVICE STABILITRACK CONSIST OF. MECHANICS HAVE NO CLEAR IDEA WHAT TO FIX. IS THERE A RECALL ON THIS SYSTEM. ANY HELP WOULD BE MUCH APPRECIATED. CHEVY HAS NO ANSWERS.

THE AIR CONTROL KNOB MAKES A TICKING SOUND. IT DOES WHEN YOU OPEN THE CAR DOOR OPENS, IF THE WIND SHIFTS, OR WHEN YOU ARE ADJUSTING THE TEMPERATURE IN THE CARR

WAS DRIVING HOME ON THE INTERSTATE WITHIN NORMAL SPEED LIMIT. ALL OF A SUDDEN HIT SOMETHING RAN OVER SOMETHING AND THE CAR BEGIN TO LOSE OIL AND SHUT OFF. WHEN TOWED TO REPAIR SHOP WAS TOLD THE ENGINE HAD A DEFECT IN IT BC IT THREW A ROD AND RUINED THE ENGINE. THE REPAIR SHOP CONFIRMED I WAS NOT AT ANY FAULT BC THERE WAS PLENTY OF OIL AND ALL NEEDED MAINTENANCE WAS UPDATE. THE REPAIR SHOP CAN'T FIGURE OUT WHY THE ENGINE WOULD THROW A ROD AND DEEMED IT A DEFECT IN THE ENGINE. THE CAR WAS BOUGHT WITH 30K MILES AND NOW ITS 130K. NEVER HAD ANY PROBLEMS UNTIL THIS AND STATEFARM INSURANCE SAYS IT DOES NOT COVER THIS SITUATION. WILL BE SEEKING IF THE MANUFACTURER WILL REPLACE IT, BC IT HAPPENED NOT AT ANY FAULT OF MINE. IF ANYONE ELSE HAVE EXPERIENCED THIS PLEASE MAKE IT KNOWN...

CAR WAS HARD SHIFTING ALWAYS WAS GETTING TO HIGH WAY SPEED LOST POWER ON ENGINE WARNING CODE CAME ON HAS ONLY LOWER 3 GEARS FORWARD NO REVERSE NOW, CHEVY WANTS ME TO PAY 3660 THEM PAY 1600 AND CALL IT A WARRENTY ,HAS LOT LEFT ON MILEAGE SHORT 5MONTHS ON WARRENTY BEING OUT NOT RIGHT THEY WANT OLD TRANSMISSION ALSO TO COVER THEIR SCREW UP

WAS DRIVING THEN ALL OF A SUDDEN THE CAR STOPPED ACCELERATING. I WAS GETTING THE FOLLOWING WARNINGS: SERVICE TRACTION CONTROL, TRACK STABILITY, AND ENGINE POWER REDUCED.

WHEN DRIVING AT LOW SPEEDS (EG 20MPH) AND THEN RE-APPLYING GAS PEDAL TO ACCELERATE THERE IS A LARGE JUMP/KICK FROM WHAT SEEMS TO BE THE LOCK UP O F TRANSMISSION AND ENGINE. ALSO THE POWERTRAIN DOESNT FEEL SMOOTH WHEN DRIVING AT HIGHWAY SPEEDS. IT SEEMS AS THOUGH SOMETHING IS LOOSE OR NOT ROTATING ON THE CORRECT AXIS. I HAVE TAKEN CAR TO DEALER AND MECHANICS ABOUT 7 TIMES THIS YEAR ALL TO NO AVAIL. THE VIBRATIONS AND UNSMOOTHNESS AREN'T EXPERIENCED IN COMPETITOR CARS THAT I HAVE DRIVEN. THIS HAS OCCURED OVER THE COURSE OF 7 MONTHS.

TL* THE CONTACT OWNS A 2013 CHEVROLET IMPALA. WHILE TURNING LEFT AT 10 MPH, THE VEHICLE STALLED AND THE ENGINE RE-ENGAGED INDEPENDENTLY. THE CONTACT DEPRESSED THE ACCELERATOR PEDAL AND THE VEHICLE JERKED BEFORE ACCELERATING. THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

ABS MULTIPLE TIMES THIS VEHICLE WILL LOCK UP THE BRAKES WHEN ATTEMPTING TO PULL OUT OF A PARKING LOT OR MAKE A TURN FROM A SLOW SPEED I.E. AN INTERSECTION THIS HAS NEARLY CAUSE MANY ACCIDENTS. AFTER DOING RESEARCH ON IT AS WELL MY VEHICLE IS NOT THE ONLY ONE WITH THIS PROBLEM ITS OUT THERE AND IT IS A HUGE SAFETY RISK. THIS PROBLEM WILL OCCUR ABOUT 80 PERCENT OF THE TIME WHEN TURNING FROM A STOPPED POSITION OR SLOW SPEED OF ANYWHERE FROM 1MPH TO 15MPH.

TL* THE CONTACT OWNS A 2013 CHEVROLET IMPALA. WHILE DRIVING 20 MPH, THE VEHICLE STALLED AND MADE A GRINDING NOISE WHEN MAKING A TURN IN THE MIDDLE OF AN INTERSECTION. THE CONTACT ALSO HEARD GRINDING NOISES WHEN THE VEHICLE WAS SHIFTED IN REVERSE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO A LOCAL DEALER, BUT WAS NOT DIAGNOSED. THE MANUFACTURER HAS NOT BEEN NOTIFIED. THE FAILURE MILEAGE WAS 81,205.

I TOOK MY CAR TO THE DEALERSHIP BECAUSE I HAD A FEW NOISES FROM THE FRONT END. ONE WAS A CLUNKING NOISE WHEN I REACHED SPEEDS OF APPROX 25 MPH, THE FRONT END WAS MAKING A POPPING NOISE, WHEN I WOULD BACK UP THEN PULL FORWARD THERE WAS A GRINDING NOISE, AND ALSO A FEW TIMES WHEN I WOULD MAKE A LEFT HAND TURN IT WAS LIKE MY CAR WAS STUCK FOR A FEW SECONDS WITH THE MOTOR REVVING, BUT WOULDNT MOVE. WHEN IT FINALLY WOULD, IT WOULD SHOOT FORWARD AND I ALMOST LOST CONTROL OF THE VEHICLE. WHEN I TOOK IT TO THE DEALER, I WAS TOLD BOTH LOWER CONTROL ARMS AND THE RIGHT FRONT HUB HAD EXCESSIVE PLAY, THE FRONT ENGINE, REAR ENGINE, STRUT MOUNT, AND TRANSMISSION MOUNT WERE TORN, THE FRONT TIMING COVER AND THE STEERING GEAR RACK WERE LEAKING AND ALL NEEDED TO BE REPLACED. SO...

TL* THE CONTACT OWNS A 2013 CHEVROLET IMPALA. WHILE DRIVING 10 MPH AND MAKING A LEFT TURN, THE ABS, TRACTION CONTROL, SERVICE BRAKE ASSIST, AND CHECK ENGINE LIGHTS ILLUMINATED. THE VEHICLE BEGAN TO DECREASE IN SPEED WHILE THE ACCELERATOR PEDAL WAS BEING DEPRESSED. ON SEVERAL OCCASIONS, WHILE THE VEHICLE WAS IN REVERSE, AN ABNORMAL NOISE COULD BE HEARD. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS APPROXIMATELY 39,000.

TL* THE CONTACT OWNS A 2013 CHEVROLET IMPALA. WHILE DRIVING APPROXIMATELY 70 MPH, THE TRANSMISSION SHIFTED INDEPENDENTLY FROM DRIVE TO NEUTRAL AND THE VEHICLE STALLED. THERE WERE NO WARNING LIGHTS ILLUMINATED. THE VEHICLE WAS COASTED TO THE SIDE OF THE ROAD. AFTER RESTARTING, THE VEHICLE RESUMED NORMALLY. THE FAILURE RECURRED THREE TIMES. THE VEHICLE WAS TAKEN TO THE DEALER, BUT WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 18,000.

MY 2013 IMPALA LTZ WILL SUDDENLY DECELERATE TO AROUND 35 MPH AND HESITATE WHEN YOU HIT THE GAS. THREE MESSAGES POP UP, "TRACTION CONTROL OFF", "ENGINE POWER IS REDUCED" AND "SERVICE STABILITRAK". THIS HAPPENED TO ME A FEW MONTHS AGO AND I BROUGHT IT RIGHT IN TO GLOBAL CHEVY IN NORTH PLAINFIELD, NJ. THEY FIXED AND IT SEEMED FINE BUT NOW HAPPENING AGAIN BUT THIS TIME, I ALMOST GOT T-BONED IN AN INTERSECTION. I HAVE FOUND THIS HAS HAPPENED TO MANY PEOPLE IN MANY DIFFERENT FORUMS. NOW I NEED TO GET THE VEHICLE TO THE DEALER AGAIN. THIS SHOULD BE A RECALL!!!!!!!! I ALMOST GOT SMASHED AND I WILL BE MAKING SURE THIS IS DOCUMENTED IN AS MANY FORUMS AS POSSIBLE. THIS IS A CHEVY PROBLEM. I GOT CHARGED OVER $650 TO FIX THIS LAST TIME!!!!!!!! I AM UPSET AS HELL AND NOT REALLY SURE WHAT TO MAKE OF THIS....

GRINDING NOISE FROM FRONT AND ABS ENGAGES THE BRAKES AND LOW TRACTION LIGHT FLASHES ON WHEN ACCELERATING FROM A STOP AND TURNING LEFT AT THE SAME TIME, DOES NOT MATTER IF YOU ACCELERATE SLOW OR FAST AND THIS IS HAPPENING ON DRY PAVEMENT. IF I TURN OFF THE TRACTION CONTROL IT WILL NOT DO IT, SO I ASSUME THE PROBLEM MUST EXIST IN A SPEED SENSOR OR SOMETHING WITH THE TRACTION CONTROL SENSORS OR WIRING. OF COURSE MECHANICS CANNOT DUPLICATE THIS. WAITING FOR GM TO STEP UP TO THE PLATE AND FIX.

FIRST MY SERVICE ABS TRACTION CONTROL LIGHTS CAME ON AND WHILE MAKING LEFT TURNS A LOUD METAL GRINDING NOISE HAPPENED AND MY TRACTION CONTROL LIGHT FLASHED. I TOOK IT TO MY LOCAL MECHANIC HE REPLACED THE BEARING AND SENSORS WHICH HELPED WITH THE SERVICE LIGHTS BUT THE GRINDING STILL HAPPENED. THE NOISE AND TRACTION CONTROL LIGHT STILL CONTINUED WHILE TURNING JUST NOT AS MUCH AS BEFORE. THE MECHANIC REPLACED THE PART TWICE!! TOOK IT TO MY MECHANIC AGAIN BECAUSE OF THE GRINDING AND TRACTION CONTROL FLASHING HE DROVE IT AROUND AND HE COULD NOT MAKE THE NOISE HAPPEN SO HE COULD NOT FIX OR REPLACE ANYTHING. IT FEELS LIKE THE ABS IS BRAKING ON ITS OWN FOR NO REASON WHILE I DRIVE MY 2013 IMPALA LTZ. MY MECHANICS CAN NOT FIND THE PROBLEM AND IT SEEMS NEITHER CAN ANY IMPALA OWNER OR MECHANIC. BUT I'M 99% SURE WHEN I DRIVE...

2013 CHEVY IMPALA WITH APPROXIMATELY 38860 MILES. 3.31.2015 DEVELOPED A GRINDING NOISE IN THE FRONT END WHEN TURNING SHARP LEFT, CAUSES THE CAR TO HESITATE, MAKING IT A VERY DANGEROUS. OCCURRED A FEW TIMES BEFORE THE DEALERSHIP OPENED. I TOOK IT INTO BOWMAN CHEVY IN CLARKSTON THEY DROVE IT & IT DIDN'T OCCUR FOR THEM AND THEY SENT ME ON MY WAY. IT CONTINUED TO HAPPEN, & WITH GREAT CONCERN FOR MY SAFETY I TOOK IT TO A DIFFERENT DEALERSHIP, JOE LUNGHAMER CHEVROLET IN WATERFORD. THEY DID KEEP MY CAR ALL DAY & GAVE ME A INVOICE THAT STATES: NPF OPERATING TO MANUFACTURING SPECIFICATIONS AND MULTI-POINT INSPECTION WAS DONE. THEY GAVE MY CAR BACK & SAID THEY FOUND NOTHING WRONG. SAD TO SAY GENERAL MOTORS MAY BE PUTTING MY LIFE IN DANGER, AS THEY DID MANY OTHER PEOPLE BEFORE RECALLING FOR THE IGNITION CONTROL. AT THIS TIME MY CAR IS...

TL*THE CONTACT OWNS A 2013 CHEVROLET IMPALA. THE CONTACT STATED WHILE ATTEMPTING TO OPERATE THE VEHICLE FORWARD OR IN REVERSE, A LOUD NOISE WAS HEARD AND A WARNING LIGHT ILLUMINATED. THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE CONTACT RECEIVED NOTICE OF NHTSA CAMPAIGN NUMBER: 14V355000 (ELECTRICAL SYSTEM). THE VEHICLE WAS REPAIRED BUT THE FAILURE PERSISTED. THE APPROXIMATE FAILURE MILEAGE WAS 30,000.

CAR HAS A GRINDING NOISE AND HESITATES WHEN TAKING A LEFT TURN FROM A STOP. ONLY HAPPENS INTERMITTENTLY AT THIS POINT. FEELS LIKE THE TRACTION CONTROL COMING ON FOR NO REASON. (BUT THEN I AM NOT A MECHANIC) NO INDICATOR LIGHTS ON THE DASHBOARD COME ON WHEN IT HAPPENS. IT IS DANGEROUS BECAUSE THE CAR HESITATES AND PULLING OUT INTO TRAFFIC THIS IS AN UNCOMFORTABLE SITUATION. SOMETIMES IT MAY HAPPEN 5 TO 6 TIMES A DAY AND THEN IT STOPS AND DOESN'T HAPPEN FOR DAYS OR WEEKS AGAIN. DOES NOT SEEM TO BE RELATED TO WEATHER CONDITIONS AS IT HAPPENS AT ALL DIFFERENT TIMES. BROUGHT IT TO THE DEALER AND THEY CANNOT DIAGNOSE THE ISSUE BECAUSE IT DOESN'T HAPPEN WHEN THEY DRIVE IT. THEY CHECKED THE CAR AND CANNOT FIND A PROBLEM. TOLD TO BRING IT BACK IF THE PROBLEM PERSISTS AND GETS MORE FREQUENT. *TR

TL* THE CONTACT OWNS A 2013 CHEVROLET IMPALA. THE CONTACT STATED THAT WHEN DEPRESSING THE ACCELERATOR PEDAL, THERE WAS AN ABNORMAL NOISE AND THE VEHICLE HESITATED TO ACCELERATE. IN ADDITION, AN UNKNOWN WARNING LIGHT ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 54,000.

2013 CHEVY IMPALA WITH APPROXIMATELY 43000 MILES DEVELOPED A GRINDING NOISE IN THE FRONT END WHEN IT WAS TURNED SHARPLY TO THE LEFT AT LOW SPEEDS (5MPH), ALSO THE TRACTION CONTROL LIGHT WOULD BEGIN TO FLASH. IT BECAME SO SEVERE THAT IT CAUSED THE FRONT END OF THE CAR TO NOSE DIVE ON SEVERAL OCCASIONS. CAR WAS TAKEN TO A CHEVY DEALER, MECHANIC FOUND FRONT RIGHT WHEEL BEARING HUB LOOSE AND BAD. REPLACED WHEEL BEARING HUB AT A COST OF $350, DEALER CLAIMED WHEEL BEARING HUB NOT COVERED UNDER POWERTRAIN WARRANTY OR UNDER ANY RECALLS. *TR

TRACTION CONTROL ACTIVATES WHILE MAKING LEFT TURNS WHEN LEAVING A STOP OR A RED LIGHT SIGN OR AT ANY OCCASION THAT REQUIRES MAKING A LEFT TURN AFTER BEING STOPPED. CAUSING THE VEHICLE TO HESITATE AND IN THE PROCESS CREATING A VERY DANGEROUS SITUATION. THIS HAS OCCURRED ON TWO OCCASIONS DURING THE PAST FEW MONTHS. HAS ONLY OCCURRED WHEN TURNING LEFT FROM A COMPLETE STOP. *TR

WHEN TURNING THE WHEEL TO THE LEFT AT LOW SPEEDS (LIKE WHEN BACKING OUT OF MY DRIVEWAY) THE ABS LIGHT COMES ON; THE FRONT LEFT WHEEL MAKES A GRINDING NOISE IN CONJUNCTION WITH THE LIGHT BLINKING; THERE IS AN IMMEDIATE LOSS OF POWER, LIKE THE CAR IS BEING HELD BACK BY SOMETHING. SAME HAPPENS WHEN TURNING, ON A HILL COMING FROM A COMPLETE STOP BUT THIS IS RANDOM AND NOT EASILY RE-CREATED. I'VE ALSO NOTICED A WOBBLE IN THE STEERING WHEN TAKING BENDS ON THE HIGHWAY AT HIGH SPEEDS. IT SEEMS TO HAVE GOTTEN WORSE SINCE I TOOK IT IN FOR SERVICE A FEW DAYS AGO. I'VE RESORTED TO TURNING THE TRACTION CONTROL OFF BEFORE PUTTING THE CAR IN DRIVE AND THIS SEEMS TO AMELIORATE THE PROBLEM. TOOK THE VEHICLE IN FOR SERVICE AND DEMONSTRATED THE PROBLEM TO THEM AND THEY AGREED THAT IT WAS OBVIOUSLY NOT PERFORMING AS IT...

FROM A STOP MAKING A LEFT TURN THE TRACTION CONTROL GOES ON AND PREVENTS ACCELERATION . ALMOST GOT HOT 3 TIMES ON CORNERS. *TR

TRACTION CONTROL ENGAGES AND LIGHT COMES ON AND GOES OFF AND ENGINE REDUCES POWER AND ABS PUMP COMES ON ALL AT THE SAME TIME. OCCURS INTERMITTENT AND ONLY WHEN IT SITS FOR A DAY AND WHEN YOU BACK OUT OF A PARKING SPACE AND THEN PUT IT IN FORWARD GEAR TO GO FORWARD. HAVEN'T HAD IT TO A DEALER YET BUT WAS TOLD THAT IF IT WASN'T SHOWING A CODE THAT THEY WOULD DO ANYTHING ABOUT IT. CAR IS A 2013 CHEVY IMPALA LTZ WITH 32000 MILES. *TR
