NHTSA Complaint #11180399 — 2014 CHEVROLET IMPALA

BLIND SPOT DETECTION SYSTEM BEGAN TO FAIL, INDICATED BY THE SIDE MIRROR INDICATORS REMAINING ON EVEN AFTER THE CAR WAS SHUT OFF. DEALER SERVICE CENTER DIAGNOSTIC TEST SHOWED THE BATTERY WAS OLD. THE PROBLEM PROGRESSED TO THE POINT WHERE THE INSTRUMENT CLUSTER WOULD ALSO FAIL - ALL INSTRUMENTS (SPEEDOMETER, TACHOMETER, ETC.) WOULD GO DEAD, VIRTUALLY ALL WARNING LIGHTS (TRACTION CONTROL, ABS, AIR BAG, ETC.) WOULD GO ON, HEATING SYSTEM (INCLUDING BLOWER) WOULD GO DEAD AND TURN SIGNALS AND HAZARD LIGHT WOULD BE INOPERATIVE. ALL OF THIS WOULD HAPPEN WHILE DRIVING, WHETHER IN CITY TRAFFIC OR AT HIGHWAY SPEEDS. ALTHOUGH THE MAIN OPERATION OF THE VEHICLE HAS NOT YET BEEN AFFECTED, THERE IS NO WAY TO SIGNAL OTHER DRIVERS OF A PROBLEM (NO HAZARD LIGHT OR TURN SIGNALS) IN THE EVENT OF A LARGER FAILURE. RESEARCH OF ONLINE CUSTOMER FORUMS SHOWS THAT THIS PROBLEM IS COMMON WITH THE LATEST GENERATION (2014 AND NEWER) IMPALA. THE BLIND SPOT DETECTION SYSTEM IS CONNECTED TO THE INSTRUMENT CLUSTER AND THIS OCCURS RANDOMLY WHILE DRIVING.
