NHTSA Complaint #10296634 — 2006 GMC ENVOY XL

VEHICLE HAS BEEN LOSING VOLTAGE WHEN CAR IS STARTED AND IN IDLE POSITION. WHEN CAR IS DRIVING THE VOLTAGE IS ALWAYS READING OK BUT WHEN YOUR AT A STOP LIGHT THEN ALL THE INSTRUMENT LIGHTS DIM AND THE BATTERY GETS DOWN TO 10 AND SOMETIMES THE CAR STARTS TO STALL. BROUGHT THE CAR TO DARCY MOTORS IN JOLIET, IL AND THEY SAID ITS NORMAL AND THE ENVOYS EXPERIENCE THIS. I DON'T BELIEVE THIS AND THE CAR IS 3 YRS OLD AND HAS 80K FOR MILES AND ITS BEEN RUNNING FINE UP UNTIL THE PAST 2MO SINCE WE HAVE BEEN EXPERIENCING PROBLEMS. WE EVEN WENT TO SEARS AND PURCHASED A NEW BATTERY AND IT STILL HAS THE SAME PROBLEMS. I BROUGHT THE ENVOY TO AUTOZONE AND PEPBOYS AND BOTH PLACES CHECKED THE ALTERNATOR, BATTERY AND ALL CABLED AND CONNECTIONS AND ALL TESTED GOOD. I DON'T KNOW WHAT THE PROBLEM IS BUT GMC NEEDS TO RESOLVE THIS ISSUE ASAP. *TR
