2009 Chevrolet Impala

WHILE ACCELERATING AFTER A STOP AT A RED LIGHT THE THROTTLE LOST RESPONSIVENESS. THE CHECK ENGINE LIGHT CAME ON AND THREE MESSAGES APPEARED ON THE DASH BOARD DISPLAY. 1. 'SERVICE STABILITRACK' 2. 'TRACTION CONTROL MALFUNCTION' FOLLOWED BY 3. 'REDUCED ENGINE POWER'. VEHICLE WOULD NOT ACCELERATE BEYOND 40MPH. I WAS ON A DOWN RAMP HEADING TOWARD A HIGHWAY WITH NO BREAKDOWN LANE AVAILABLE. VERY DANGEROUS SITUATION. NEXT MORNING I BROUGHT THE VEHICLE INTO A LOCAL CHEVROLET DEALER AND CODE P2138 REVEALED "ACCELERATOR PEDAL/SENSOR FAILURE." REPAIR COST $265. MANY OTHER CHEVROLET OWNERS COMPLAIN OF THIS SAME ISSUE AND THE DANGEROUS SITUATION THE ACCELERATION LOSS CAUSES. PLEASE SEE THIS EDMUNDS.COM BLOG WITH DOZENS OF OTHERS COMPLAINING OF THIS SAME ISSUE.

THE VEHICLE SUDDENLY DECELERATED AND DISPLAYED MESSAGES: "REDUCED ENGINE POWER" AND "SERVICE TRACTION CONTROL". THIS WAS THE SECOND INCIDENT. THE FIRST INCIDENT RESULTED IN THE ENGINE SHUTTING OFF COMPLETELY AFTER THE SAME INITIAL SYMPTOMS DESCRIBED; LOCKING UP THE STEERING DURING RUSH HOUR TRAFFIC (ESTIMATED 65 MPH, NO INJURES, APPROX. 4 MONTH AGO). OUR MECHANIC CLEANED OUT THE THROTTLE BODY SENSOR AFTER THE FIRST INCIDENT, AND PHONED THE DEALERSHIP WITH THE TROUBLE CODES. THE DEALERSHIP REFUSED WARRANTY SERVICE AS THE TROUBLE CODES HAD GONE BY THE TIME THE CAR HAD ARRIVED AT THEIR SHOP, AND WOULD NOT TAKE OUR MECHANIC'S PHONE CONVERSATION AS EVIDENCE. WE WERE INFORMED THAT THE THREE SERVICES COMMONLY PERFORMED TO FIX THE PROBLEM WERE TO REPLACE THE THROTTLE BODY, THROTTLE BODY SENSOR, AND ACCELERATOR PEDAL; THE LATTER NOT COVERED UNDER WARRANTY. *TR

I WAS DRIVING ON THE HWY WHEN THE MESSAGE APPEAR ON THE BOAR "ENGINE POWER REDUCE " I WAS SCARED BECAUSE I HAVE NEVER HAD THAT PROBLEM. I WHEN ONLINE AND SAW THAT PEOPLE WERE HAVING THE SAME PROBLEM. IT WAS WEIRD BECAUSE THEY ALL SEEN TO BE IN THE SAME MONTH LIKE IF IT WAS PROGRAM TO HAPPEN. SO I WANT AN EXPLANATION ON WHAT'S GOING ON WITH MY CAR? WHAT'S THE MESSAGE ABOUT? DO I HAVE TO CHANGE THE MOTOR ? I JUST DON'T KNOW WHAT TO DO ANYMORE THIS CAR HAS A LOT OF PROBLEM I JUST WANT SOME ANSWERS . THANKS FOR READING. *TR

TRACTION CONTROL WARNING LIGHT CAME ON THEN IT SAID REDUCED ENGINE POWER THEN IT SHUT THE ENGINE OFF GOING 65 DOWN THE HIGHWAY WITH MY [XXX] YEAR OLD DRIVING IT. THE POWER STEERING WAS NOT WORKING SO SHE COULD HARDLY GET THE CAR OFF THE ROAD AND ALMOST WAS HIT BY A LARGE TRUCK. THIS IS DANGEROUS. I WON'T LET HER DRIVE IT AND IT HAPPENED TO ME THE NEXT DAY. *TR PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
