NHTSA Complaint #10456713 — 2006 GMC ENVOY XL

WHEN TURNING CORNERS ON SMOOTH ASPHALT THE STABILITRAC LIGHT COMES ON AND ENGAGES THE SYSTEM WHICH CAUSES THE VEHICLE TO MOMENTARILY SLOW DOWN AND MAKES A "GROWL" SOUND, THIS ALSO EFFECTS THE STEERING. IT MAY DO THIS MULTIPLE TIMES PER TURN OR ONLY ONCE. IT HAS OCCURRED AT VARYING SPEEDS (TURNS AT 45MPH AND TURNS AT 10MPH). STARTED OUT ONLY OCCURRING DURING LEFT HAND TURNS, NOW HAPPENS ON ALMOST ALL TURNS. I HAVE NOTICED IT IS MUCH WORSE ON WINDY DAYS. THE STABILITRAC ALSO KICKS IN WHEN I TURN ONTO GRAVEL AND START TO SPEED UP (NOT MASHING THE GAS AND SPINNING TIRES, BUT SIMPLY SPEEDING UP AT A REGULAR PACE THAT SHOULD NOT POSE PROBLEMS). *TR
