2009 Lincoln MKS Speed Control & Cruise Problems

ACCELERATOR PEDAL JAMMED AND ENGINE WAS REVVING HIGH AT 5000 , I HAVE PRESS HARD ON THE BRAKE TO SLOW DOWN TO AVOID HITTING OTHER CARS WHILE TRYING TO PULL AWAY SAME WAY LIKE THE PREVIOUS INCIDENT THAT HAPPENS 7 MONTHS EARLIER. I THEN DISENGAGED THE TRANSMISSION TO NEUTRAL TO BE ABLE TO CUT OFF THE ENGINE , WAIT FOR 10 AND SHAKE THE GAS PEDAL , BEFORE I CRANKED UP AND CONTINUED TO GO ON .

IN DECEMBER 2013, I TOOK MY 2009 LINCOLN MKS TO THE DEALER FOR SERVICE BECAUSE IT OCCASIONALLY ACCELERATES BEFORE SLOWING DOWN WHEN I APPLY THE BRAKES. ON A DIFFERENT OCCASION I WAS BEHIND A CAR THAT SLOWED DOWN THEN CAME TO A COMPLETE STOP TO AVOID HITTING A DEER. I APPLIED THE BRAKES, MY CAR SLOWED DOWN AND MADE A WEIRD NOISE AS IF THE CAR WAS TRYING TO START UP; INSTEAD OF COMING TO A COMPLETE STOP, IT KEPT GOING WHILE MY FOOT WAS ON THE BRAKES. THE TECHNICIAN DROVE ME AND MY SON AROUND THE BLOCK BUT COULD NOT DUPLICATE THE PROBLEM. I WAS INFORMED THAT IF THE CHECK ENGINE LIGHT IS NOT ON, OR IF THERE ARE NO CODES, AND IF THEY CANNOT DUPLICATE THE PROBLEM, THERE WAS NOTHING THEY COULD DO. ON JANUARY 14, 2014 AS I PULLED INTO MY CARPORT BEFORE COMING TO A COMPLETE STOP, THE CAR MADE THE SAME WEIRD NOISE, AND CONTINUED GOING FORWARD AND PUSHED ITS WAY INTO THE SIDE OF MY HOUSE WHILE MY FOOT WAS ON THE BRAKE. WHEN THE NOISE STOPS, THE CAR STOPS. I TOOK THE CAR BACK TO THE DEALER ON JANUARY 20, 2014 AND THEY KEPT THE CAR TO DRIVE TO SEE IF THEY HAD A SIMILAR EXPERIENCE. THEY TOLD ME THEY COULD NOT FIND ANY PROBLEMS WITH THE CAR. I CAN UNDERSTAND THAT THEY CANNOT FIX A PROBLEM IF THEY CAN'T DUPLICATE IT, BUT THE PROBLEM IS SPORADIC. WHAT DISTURBS ME THE MOST IS THAT WHEN I GAVE DETAILS OF THE PROBLEMS TO THEIR SERVICE DEPARTMENT, THE FIRST TIME ON THE WRITE-UP THEY ONLY REPORTED THAT I HEAR A NOISE UPON ACCELERATION. THE SECOND TIME THEY DIDN'T GIVE ME ANY PAPERWORK. IF THEY ARE ONLY TELLING THEIR REPAIR DEPARTMENT TO CHECK FOR NOISE UPON ACCELERATION, THEN THEY WOULD NOT BE CHECKING THE CAR FOR THE ACTUAL PROBLEMS. I HAVE BEEN FORTUNATE BOTH TIMES THAT NO ONE WAS INJURED. *TR

AS I WAS DRIVING THE GAS PEDAL GOT LOCKED AS I WAS APPROACHING A STOP SIGN AND THE ENGINE WAS REVVING HIGH AT 5000 RPM . I TRIED TO TURN OFF THE ENGINE BUT IT WILL NOT RESPOND , SO I HAD TO MAKE A SUDDEN RIGHT TURN ONTO A LESS TRAVELED STREET TO AVOID HITTING OTHER CARS . I THEN DISENGAGED THE TRANSMISSION TO NEUTRAL TO BE ABLE TO SHUT THE ENGINE OFF .

TL*THE CONTACT OWNS A 2009 LINCOLN MKS. WHILE DRIVING APPROXIMATELY 35 MPH APPROACHING A STOP SIGN HE ENGAGED THE BRAKES AND THE VEHICLE ACCELERATED. HE STATED THAT THE VEHICLE ACCELERATED UP TO 4000 RPMS AND BEGAN TO SLOW DOWN ON ITS OWN. HE DID NOT CONTACT THE DEALER. THE FAILURE OCCURRED AGAIN WHILE DRIVING 25 MPH; YET, HE ENGAGED THE BRAKES AND THE VEHICLE ACCELERATED. HE SHIFTED INTO NEUTRAL GEAR IN ORDER TO SLOW THE VEHICLE DOWN. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER AND THEY WERE UNABLE TO LOCATE THE FAILURE. THE CONTACT STATED THE FAILURE OCCURRED INTERMITTENTLY. HE CONTACTED THE MANUFACTURER AND THEY REFERRED HIM TO NHTSA. THE FAILURE MILEAGE WAS 1,000 AND THE CURRENT MILEAGE WAS 14,700. UPDATED 08/24/10. *LJ UPDATED 08/25/10*JB
