2011 Chevrolet Impala

2011 IMPALA 3.5L V6 SFI (LZE)OCTOBER, 2016 (60,104 MI) WHILE TRAVELING 60 MPH, THE VEHICLE LOST POWER. DROPPED DOWN TO 20 MPH WHILE ENGINE SURGED. DISPLAY READ, " SERVICE TRACTION CONTROL," SERVICE STABILITRACK," "ENGINE POWER REDUCED." BY FEATHERING THE GAS PEDAL, I WAS ABLE TO GET THE SPEED UP TO 40-45MPH AND DROVE 1 MILE TO GM DEALERSHIP. AT TRAFFIC LIGHT THE VEHICLE SURGED WHILE STOPPED AND NEEDED VERY FIRM BRAKING TO KEEP IT FROM SURGING AHEAD. THE DEALERSHIP STAFF "GUESSED" THAT IT WOULD BE THE THROTTLE POSITION SENSOR WITHOUT DOING DIAGNOSTIC CHECK - I ASSUMED THIS WAS A COMMON PROBLEM. I TOOK MY VEHICLE TO LDA AUTO WHERE THE OWNER/EXPERT ON VEHICLE ELECTRICAL SYSTEMS INSTALLED AN AFTERMARKET THROTTLE BODY ASSEMBLY (PART = $254); THE THROTTLE POSITION SENSOR IS AN INTEGRAL PART OF THE THROTTLE BODY ASSEMBLY SO THE ENTIRE PIECE HAD TO BE REPLACED. A "RELEARN PROCEDURE" WAS PERFORMED. ANY NEEDED ADJUSTMENTS MADE. CODE SYSTEM RESET AND TESTED. VEHICLE WAS TEST-DRIVEN. (LABOR = $80). I DROPPED MY VEHICLE OFF AT 7:00AM, GOT A RIDE TO WORK FROM SHOP STAFF, AND RECEIVED MESSAGE THAT MY VEHICLE WAS COMPLETED SAME DAY. OWNER EVEN DEDUCTED THE $20 "SHOP SUPPLIES" FEE FROM MY BILL BECAUSE HE STATED HE DID NOT USE ANY SUPPLIES. KUDOS FOR HIS HONESTY!!! TOTAL BILL CAME TO A LITTLE LESS THAN $350. OWNER SHOWED ME EXACTLY WHAT HE DID, OFFERED TO GIVE ME THE OLD PART, LET ME CHOOSE WHICH MFG TO ORDER FROM ONLINE. CAN'T SAY ENOUGH GREAT THINGS ABOUT THIS EXPERIENCE! TODAY IS 2/23/2017 AND MY IMPALA HAS NOT HAD ANY OTHER PROBLEMS SINCE THIS REPAIR; IN FACT, IT SEEMS TO BE A BIT MORE RESPONSIVE.

TAKATA RECALL THIS ISSUE IS THIS: I BOUGHT THE CAR IN DECEMBER 2015 FIRST MY ENGEN LIGHT COMES ON, THAN MY TRACTION CONTROLE LIGHT, THAN MY CAR TELLS ME TO SERVICE TRACTION CONTROLE, ENGEN POWER IS REDUCED, SERVICE STABIL TRACK, THE ENGEN CUTS I LOOSE POWER STEERING, AND I HAVE TO PULL OVER FOR 15 MIN WAITING FOR THE CAR TO REBOOT. I HAVE HAD THE CAR TO THE GM SHOP EVERY 2500-3000 MILES. THE SHOP REPLACED ALL THE FACTORY COVERED PARTS AND NOW WILL START GUESSING. THE FIRST FIX IS REPLACING SOME WIRES THAT ANOTHER SHOP REPLACED IN AN ATTEMPT TO FIX THIS SAME PROBLEM. NO ONE WILL FIX THIS DEATH TRAP. I WILL NOT DRIVE IT.

DRIVING DOWN THE HIGHWAY THE CAR SHOOK AND JERKED THEN THE ENGINE POWER REDUCED, SERVICE STABILITRACK, AND SERVICE TRACTION CONTROL SHOWED UP ON MY DASHBOARD. THE CHECK ENGINE LIGHT CAME ON AND SO DID THE TRACTION LIGHT AND THEY STAYED ON. THE RPM METER IS AVERAGING BETWEEN 3 AND 4 WHEN IT USUALLY AVERAGES BETWEEN 1 AND 2. ALSO, THE SPEED HAS BEEN REDUCED.

I HAVE PROBLEM WITH THE STABILITRAK/TRACTION CONTROL ON A 2011 IMPALA WITH 120,000 MILES. I HAVE FOUND OTHER PEOPLE FROM ALL OVER THE COUNTRY WITH THE SAME PROBLEM. I HAVE TAKEN IT TO 3 DIFFERENT MECHANICS AND THEY ARE ALL UNSURE AS TO WHAT IT IS. I HAVE PUT A NEW THROTTLE BODY IN, NEW SPARK PLUGS, CHANGE MY OIL FAITHFULLY EVERY 3,000 MILES. IT CONTINUES TO FLASH THE MESSAGE TO ME, DOES NOT HAVE THE SAME ACCELERATION, IS VERY UNPREDICTABLE AS FAR AS REDUCING MY ENGINE POWER AT ANY GIVEN TIME. THIS HAPPENS WHEN I'M DRIVING DOWN THE ROAD AND EVEN WHEN I JUST START MY CAR. I HAVE TO TURN CAR OFF, LET IT SIT FOR A FEW MINUTES AND THEN IT SEEMS TO RESET BUT THE ENGINE LIGHT STAYS ON FOR A FEW DAYS. THIS NEEDS TO BE ADDRESSED WITH AS MANY COMPLAINTS I AM READING ABOUT!

TL* THE CONTACT OWNS A 2011 CHEVROLET IMPALA. WHILE DRIVING 65 MPH, THE ENGINE STALLED AND THE ENGINE STABILITY POWER REDUCTION WARNING LIGHT ILLUMINATED. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE ACCELERATOR PEDAL AND RE-LEARNED IDLE FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. ALSO, WHILE DRIVING AT VARIOUS SPEEDS, THE GEAR SHIFT BECAME INOPERABLE. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION WAS FAILING AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS APPROXIMATELY 44,815. UPDATED 01/12/16*LJ *CN *TR

WHILE AT A COMPLETE STOP, WHEN THE VEHICLE IS IN DRIVE, AS I ATTEMPT TO PUSH THE ACCELERATOR TO DRIVE THROUGH AN INTERSECTION, THE CAR WILL STALL FOR A SECOND, MAKE NOISE THAT SOUNDS LIKE A WHINE, AND THEN JUMP FORWARD LIKE IT'S HAVING A DIFFICULT TIME FINDING FIRST GEAR. THE VEHICLE DOES THIS EVERY SO OFTEN, BUT NOT ALL THE TIME. I'VE TAKEN IT INTO CAR X, MY LOCAL CHEVROLET DEALERSHIP, AND ANOTHER LOCAL GOODYEAR TIRES DEALER, BUT NOBODY HAS ANY IDEA WHAT I'M TALKING ABOUT. THE VEHICLE HAS BEEN HOOKED UP TO A COMPUTER AND TECHNICIANS HAVE LOOKED AT IT, BUT JUST SCRATCH THEIR HEADS. THERE IS EVEN A FORUM ONLINE REGARDING THIS HAPPENING WITH OTHER CHEVY IMPALA OWNERS [XXX] AND OWNERS SEEM TO PUT LOTS OF MONEY INTO THE ISSUE BUT WITH NO RESOLVE. ** THE ISSUE SEEMS TO REMEDY ITSELF WHEN I TURN OFF THE TRACTION CONTROL. ** THERE HAVE BEEN A COUPLE OF CLOSE CALLS WHERE I'LL BE PULLING THROUGH A BUSY INTERSECTION AND THE CAR WILL STALL AND I'LL FEEL LIKE I'M ABOUT TO BE HIT BECAUSE THE CAR "DIES" FOR A SECOND. I FEEL THIS IS A REAL SAFETY CONCERN THAT NEEDS TO BE ADDRESSED.
