2009 Mercury Sable Powertrain & Transmission Problems

HAVING DRIVEN 150 MILES OR SO OF HIGHWAY DRIVING USING CRUISE CONTROL, STOPPING TWO TIMES TO REST, DRIVING APPROX. 65 - 70 MPH. I ARRIVED AT WALTHAM ON RT. 128 WHERE THE TRAFFIC WAS BUMPER TO BUMPER. I HAD TO KEEP MY FOOT ON THE BRAKE UNTIL I WAS AT EXIT 38 OR 39. WE TRAVELLED 5 - 15 MPH. AFTER I WAS IN THE SLOW TRAFFIC FOR APPROX. 20 MINUTES MY CAR STARTED TO LURCH FORWARD WHILE GASSING UP AND WANTING TO JUMP AHEAD. MY FOOT WAS ON THE BRAKE AND I NEEDED TO BRAKE EVEN HARDER TO HOLD ONTO THE FORCE THAT THE CAR WAS EXERTING. I WAS IN BUMPER TO BUMPER TRAFFIC AND HAD KEPT A DISTANCE BETWEEH MYSELF AND THE CAR IN FRONT SO THE SMALL JUMP DID NOT HIT THAT CAR BEFORE I PUSHED HARDER ON THE BRAKE. THE SAME THING HAPPENED AGAIN WITHIN 5 MINUTES. ONCE I ARRIVED IN DANVERS I DROVE TO THE DEALER TO REPORT THE PROBLEM AND THEY GAVE ME AN APPOINTMENT FOR WEDNESDAY8/28/13. THIS SAME PROBLEM HAS BEEN HAPEENING SINCE I PURCHASED THE CAR IN 2011. IT SELF ACCELERATED RANDOMLY EVERY 3-4 MONTHS, IT HAPPENED WHEN I HAD MY FOOT ON THE BRAKE AND I WAS AT A TRAFFIC LIGHT WITH MY MOM IN THE CAR. I ALMOST WENT THROUGHT THE LIGHT FROM A STOPPED BRAKED POSITION. THE OTHER TIMES WERE AFTER DRIVING WITH CRUISE CONTROL WHICH I NEED. IT ALSO HAPPENED WHILE BRAKING TO GET INTO A PARKING PLACE. *TT

THERE WAS NO ASSOCIATED SHUDDER, LURCHING, OR OTHER PHYSICAL INDICATION THAT ENGINE HAD FAILED. NO ENGINE SERVICE LIGHT OR OTHER INDICATION WAS DISPLAYED. VEHICLE TRANSMISSION WAS PLACED INTO NEUTRAL, RESTART ATTEMPTED, AND ENGINE RESUMED NORMAL OPERATION WITHOUT FURTHER INCIDENT. THIS PROBLEM HAS OCCURRED THREE TIMES IN THE LAST 120 DAYS. I CONTACTED THE DEALER, WHERE THE VEHICLE WAS PURCHASED - SENTRY FORD IN MEDFORD MA., AND THE SERVICE REP ON THE PHONE FOUND NO APPARENT REASON FOR THE MALFUNCTION OR TO SCHEDULE A DIAGNOSTIC DEALER SERVICE APPOINTMENT, SINCE NO ENGINE SERVICE LIGHT CAME ON, BASED ON MY TESTIMONIAL. HE ALSO TOLD ME THAT IF THE ENGINE SERVICE LIGHT DOES NOT COME ON, NO FAILURE CODES ARE STORED IN THE ON BOARD VEHICLE OPERATION HISTORY DATABASE AND THE PROBLEM CAN NOT BE DIAGNOSED AND THE DEALER CAN NOT PROVIDE ASSISTANCE OR GUIDANCE FOR REPAIR. *TR
