NHTSA Complaint #10469457 — 2007 GMC ACADIA

WHILE DRIVING ON THE INTERSTATE, I HAD TO BRAKE QUICKLY BECAUSE OF ACCIDENT AHEAD. AT THIS TIME, THE STABILITRAK SERVICE MESSAGE AND BRAKE MESSAGE STARTED ALTERNATELY FLASHING ON DIC. BRAKE AND STABILITRAK WARNING LIGHTS ALSO CAME ON. THE CAR DECELERATED LIKE WHEN YOU SHIFT DOWN ON A MANUAL TRANSMISSION WHEN I TRIED TO ACCELERATE AGAIN, NO RESPONSE. TRIED TURNING STABILITRAK BUTTON BACK ON AND OFF, BUT THIS DID NOTHING. AFTER A FEW SECONDS THE CAR STARTED TO ACCELERATE, THE ENGINE LIGHT CAME ON. I WAS IN HEAVY TRAFFIC AND WAS DIFFICULT TO GET OVER TO SHOULDER. I HAD ABOUT 10 MILES TO GET TO MY HOUSE, SO WATCHED THE ENGINE TEMP GAUGE, AND MADE IT HOME. ENGINE LIGHT REMAINED LIT. THE ENGINE GAUGE INDICATED THE CARS TEMPERATURE ROSE ABOUT 15 DEGREES ABOVE WHAT IT USUALLY IS .STARTED THE CAR THE NEXT DAY WITHOUT ANY WARNINGS OR MESSAGES DISPLAYED AND TOOK THE CAR TO MY MECHANIC, HE RAN THE CODES ON CARS COMPUTER. IT SHOWED NO ERRORS,WAS A LITTLE LOW ON WATER. HE SAID TO DRIVE IT AND LET HIM KNOW IF IT HAPPENED AGAIN. THE VEHICLE HAD BEEN IN OPERATION FOR ANOTHER 45 DAYS, WITH NO MORE SIGNS OF PROBLEMS. 46TH DAY, THE VEHICLE'S SERVICE MESSAGE FOR STABILITRAK AND BRAKE FLASHED AGAIN, WITH WARNING LIGHTS FOR THESE COMING ON AS WELL, AFTER CAR WAS DRIVEN APPROX. 4 MILES AND PARKED FOR ABOUT AN HOUR. THE VEHICLE OPERATED FINE. I PARKED THE CAR AGAIN FOR ABOUT ONE HOUR, WARNING LIGHTS CAME ON AFTER ABOUT A MILE THE NEXT DAY THE SAME EPISODE. NOW I'M INTO THE 2ND WEEK OF THE BRAKE AND STABILITRAK WARNING LIGHTS COMING ON AND OFF. WILL CALL THE DEALER BECAUSE AT THIS POINT I'M AFRAID OF ANOTHER GEAR DOWN LIKE THE FIRST INCIDENT AND BEING IN HEAVY TRAFFIC-THAT'S NOT SAFE HOWEVER, I'VE BEEN TO THE DEALER BEFORE ABOUT THE PASSENGER AIRBAG SENSOR SAYING IT'S OFF WHEN THERE IS A PASSENGER SITTING THERE. CHECKING CARS COMPUTER SAID ?CODES? SHOWED NOTHING WRONG? ARE THE "CODES" INFALLIBLE? *TR
