2007 CHEVROLET IMPALA Complaints

"SERVICE TRACTION CONTROL" AND THEN "ENGINE POWER REDUCED" ALTERNATING ON DASH OFTEN, WHILE DRIVING. MY MECHANIC COULD ONLY DIAGNOSE THE THROTTLE PEDAL SENSOR WAS GOING OUT. HE REPLACED THE PEDAL. TWICE, IT CONTINUES TO BE A PROBLEM. ALL MECHANICS SAY I HAVE TO TAKE IT TO DEALERSHIP, I HAVE A FEELING THIS IS A RIP-OFF.

DASH SAYS "SERVICE TRACTION CONTROL" THEN "ENGINE POWER REDUCED" WHEN THIS FIRST STARTED ABOUT 4 MONTHS AGO, I TOOK THE CAR TO MY MECHANIC. HE RAN A DIAGNOSTIC AND WHAT CAME UP WAS I NEEDED A "THROTTLE SENSOR", WHICH MEANT REPLACING THE GAS PEDAL. HE DID THIS. THAT DIDN'T WORK SO HE RE-DID THE PEDAL. STILL GETTING THE SERVICE TRACTION CONTROL MESSAGE, WITH REDUCED ENGINE POWER, THIS HAPPENS AT RANDOM, NO ONE SEEMS TO KNOW WHAT THE PROBLEM IS. NOW THE BIG PROBLEM IS- I HAVE TO GO TO THE CHEVY DEALERSHIP SERVICE AND PAY 150 BUCKS JUST FOR A DIAGNOSTIC. WHICH DOESN'T EVEN GO TOWARD SOLVING THE PROBLEM.

WHEN MY CAR IS IN MOTION IN THE STREET, TURNING, BRAKING AND DRIVING SLOW MY TRACTION CONTROL COMES ON AND SAYS REDUCE ENGINE SPEED AND THE LIGHT FOR MY ENGINE COMES ON. I DON'T KNOW WHAT IS CAUSING THIS PROBLEM AND I DONT HAVE ANY INVOICES, ANY POLICE REPORTS NOR ANY INSURANCE CLAIMS

MY CAR STARTED HAVING THE TRACTION CONTROL COME ON ABOUT 2-3 YEARS AGO. I WAS TOLD I NEEDED A NEW TRANSMISSION. THE TRANSMISSION WAS CRACKED-CHEVROLET SAID NOT THEIR FAULT, SO, I REPLACED THE TRANSMISSION. THEN, IT STARTED DOING IT AGAIN. I REPLACED THE BRAKE PADS. IT STOPPED. THEN, STARTED UP AGAIN. TOOK TO THE CHEVROLET GARAGE WHO PUT IT ON THEIR TOTAL DIAGNOSTIC MACHINE. TOLD I NEED BOTH BEARINGS ON THE FRONT. AT A $972.00 PRICE TAG FOR THIS, I BOUGHT THE BEARINGS AND HAD ANOTHER GARAGE PUT THEM ON AT A GREAT REDUCTION IN COST TO ME ON LABOR. NOW, IT IS DOING IT AGAIN. AT FIRST IT WAS ONLY EVERY ONCE IN AWHILE. THE WHEEL SENSORS APPEAR TO BE FINE. NOW I NOTICE IT IS DOING IT A LOT MORE AND STARTING TO DO IT WHEN I ACCELERATE FROM A STOP AT CERTAIN TIMES. I BOUGHT THIS CAR BRAND NEW, AND, FOR ITS AGE, IT DOES NOT EVEN HAVE 60,000 MILES ON IT. (THE DATE THAT THAT I AM USING IN THE NEXT STEP HERE IT BEGAN IS THE DATE WHEN IT REALLY STARTED DOING ITS 'TRICKS' A LOT MORE).

MY ISSUE STARTED WITH MY CAR TURNING OVER. IT WOULD NOT WANT TO START FIRST TRY BUT WOULD TURN OVER ON THE SECOND. SOME TIMES IT WOULD START FINE AND OTHERS IT HESITATED. AFTER DEALING WITH THIS FOR A WHILE MY BATTERY DIED AFTER SPENDING A LITTLE WHILE IDLING. TOOK IT TO CHECK THE ACCELERATOR AND THE BATTERY BUT BOTH WERE FINE. CONTINUING TO INTERMITTENTLY ACT UP WHEN STARTING, IT ALSO STARTED TO SHOW OTHER PROBLEMS. I WAS GETTING IN MY CAR TO LEAVE AND IT STARTED UP FINE BUT BEFORE I COULD PULL OUT OF MY DRIVE WAY MY CAR STARTED SHAKING AND SHOWING AN "ENGINE POWER IS REDUCED" MESSAGE. I TURNED IT OFF RAN INSIDE AND WHEN I CAME BACK OUT TO SHOW OTHERS THE ISSUE IT STARTED WITHOUT A PROBLEM AND DID NOT HAVE THE MESSAGE ANY MORE. STILL HAVE THE TURNOVER HESITATION, I CONTINUE TO DRIVE IT HOWEVER IT STARTED TO SHAKE AND SHOW THE SAME ENGINE POWER REDUCED MESSAGE AS I PULLED INTO MY APARTMENT COMPLEX. ALSO HAS DONE THIS WHEN LEAVING AND TURNING INTO A MAIN ROAD, CAUSING US TO PULL OVER AND WAIT TO START IT AGAIN. TOOK IT TO GET CODES TESTED AGAIN AND IT PULLED UP A DIDN'T MATCH CODE. AFTER DOING RESEARCH TONS OF OTHERS HAD THE SAME PROBLEM AND WORSE. MANY SHOWED THE SOLUTION TO BE REPLACING THE THROTTLE BODY AND THROTTLE POSITION SENSOR WHICH WE DID. SLIGHT HESITATION ON THE START UP BUT TOOK IT AROUND THE BLOCK NO ISSUES. WENT TO TEST IT ON THE HIGHWAY AND BEFORE WE EVEN MADE IT THE ENGINE POWER REDUCED CAME ON AND CAR SHOOK AGAIN. THERE AND SO MANY OTHERS THAT HAVE HAD THIS PROBLEM AND MANY HAVE NOT FOUND THE FIX. EXTREMELY DISAPPOINTING SINCE WE CANNOT RETURN THE PART AFTER IT'S BEEN INSTALLED. I AM WORRIED TO TAKE MY CAR OUT AND DRIVE IT ON THE HIGHWAY BECAUSE I DO NOT WANT THIS TO HAPPEN WHILE I'M AT INCREASED SPEEDS.
