NHTSA Complaint #10508857 — 2009 CHEVROLET IMPALA

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.
