WHILE DRIVING A HIGHWAY SPEED,MY 2008 BUICK LUCERNE SHOWED A SERVICE STABILITRAK LIGHT.THIS CAUSED A LOSS OF TRACTION AND I HAD TO SLOWLY BRING THE VEHICLE UNDER CONTROL MANUALLY. THIS CONDITION LASTED A FEW SECONDS AND THEN RETURNED TO NORMAL. THIS HAS HAPPENED SEVERAL TIMES AT HIGHWAY SPEED UP TO THE PRESENT DATE. I TOOK THE VEHICLE TO MY DEALER(KARP BUICK). THEY WERE UNABLE TO REPLICATE THE PROBLEM.THE CONDITION STILL EXISTS. IT ALSO SOMETIMES SHOWS A STABILITRAK NOT READY LIGHT AND CAUSES THE SAME LOSS OF CONTROL.I UNDERSTAND THE BUICK LACROSSE,THE GMC ACADIA AND THE GMC SIERRA HAD SIMILAR PROBLEMS. *JS

SERVICE BRAKES
THE BRAKES WHEN APPLYING COMING DOWN HILLS MAKE THE FRONT END SHIMMY AND SHAKE AND IT DOES NOT WANT TO SLOW THE VEHICLE DOWN ACCORDING TO THE BRAKE PRESSURE BEING APPLIED. THIS IS A VERY SERIOUS PROBLEM AND I CALLED THE DEALER HERE IN BUTTE, MT AND THEY SAID SHE THINKS THIS IS THE WAY IT IS. THE PROBLEM HAS GOTTEN SOMEWHAT WORSE AS TIME AND USE OF THE BRAKES INCREASE AND IT IS BECOMING AS MAJOR ISSUE FOR US. WE LOVE THE CAR BUT THIS NEEDS TO BE LOOKED AT AS SOON AS POSSIBLE. THE CAR HAS 45800 MILES AS OF NOW. WE PURCHASED IT NEW IN 2006. *TR
