NHTSA Complaint #10986407 — 2012 CHEVROLET IMPALA

INTERMITTENTLY, THE DIC WILL SOUND AN ALARM AND DISPLAY THE FOLLOWING MESSAGES:SERVICE STABILITRAK, SERVICE TRACTION CONTROL. WHEN THIS HAPPENS I SOMETIMES NOTICE A DECREASE IN ENGINE POWER AND/OR GRINDING NOISES FROM THE FRONT END WHEN I MAKE TURNS. THIS HAS OCCURRED AT HIGHWAY SPEEDS AND/OR RESIDENTIAL SPEEDS AND DOES NOT COINCIDE WITH ANY ROUGH OR UNUSUAL DRIVING CONDITIONS. IT IS HARD TO UNDERSTAND WHAT CAUSES IT UNLESS IT IS SOME KIND OF ELECTRICAL SHORT CIRCUITING. I CAN TURN THE STABILITRAK OFF AND THE MESSAGES AND DIMINISHED MECHANICAL PERFORMANCE WILL STOP, BUT MAY RE-APPEAR WEEKS LATER. ACCORDING TO THE REPORTS I HAVE READ ON-LINE, THIS IS A COMMON PROBLEM AMONG IMPALA OWNERS WITH CARS OF SIMILAR YEARS AND MILEAGE. MY CAR HAS ONLY 40,000 MILES. IN AN EFFORT TO FIX THE ISSUE, OTHER OWNERS HAVE REPORTEDLY REPLACED SENSORS, WIRES, WIRE HARNESSES, HUB ASSEMBLIES, THROTTLE BODIES, AND BRAKE COMPONENTS. GENERAL MOTORS NEEDS TO RECALL OUR CARS IN ORDER TO DEAL WITH THIS PROBLEM. NONE OF THESE MECHANICAL COMPONENTS SHOULD BE FAILING SO SOON. LOSS OF ENGINE POWER AND BRAKING ABILITY WHILE DRIVING IS A POTENTIALLY DEADLY PROBLEM, AND ANY MECHANICAL ISSUE THIS WIDESPREAD AMONG CAR OWNERS SHOULD BE SUBJECT TO AN OFFICIAL RECALL AND SHOULD BE REMEDIED BY THE AUTOMAKER AT NO CHARGE TO THE PUBLIC.
