I REALIZED SOMETIME LAST YEAR THAT MY THROTTLE WAS STICKING WHEN I WOULD START THE CAR AND BEGIN TO TAKE OFF. IT WAS HERE AND THERE AND THEN I MUST HAVE GOTTEN USE TO IT BUT NOW IT DOES IT EVEN WHEN I'M DRIVING, IT STICKS ALL THE TIME. NOW IT DOESN'T WANT TO SHIFT AT THE RIGHT TIMES AND IT ACTS WEIRD A LOT, GOING UP HILLS, WHEN SHIFTING FROM GEARS AND SO ON.

I AM GETTING CONTINUAL THROTTLE BODY ERRORS ON MY 2009 MARINER. IT GOES INTO LOW POWER MODE SO I CAN "LIMP HOME". IT HAPPENS MOSTLY ON HIGHWAYS WHEN I NEED TO "PUNCH IT" AND GET ALOT OF ACCELERATION.
NHTSA complaint #11024080 — an unverified report by a vehicle owner.
VEHICLE SPEED CONTROL
THE THROTTLE IS HELD OPEN WHEN THE CRUISE CONTROL IS EMPLOYED BUT REMAINS OPEN WHEN THE CRUISE CONTROL IS TURNED OFF BOTH BY USING THE OFF BUTTON AND BRAKE APPLICATION. THIS HAPPENS AT 75-80 MPH ON INTERSTATE HIGHWAYS IN AZ AND UT. THE POWER BRAKE BOOSTER IS INEFFECTIVE WITH NO INTAKE VACUUM. THIS IS VERY DANGEROUS.

ON THE FREEWAY AND CAR SUDDENLY HAS OVERDRIVE LIGHT BLINKING, AT THE SAME TIME I BEGAN LOSING POWER, I WAS ABLE TO GET OFF FREEWAY BUT NOT AFTER I OPEN HOOD AND NEARLY GOT RUN OVER. I WAS CHECKING TO SEE IF THERE WAS OVERHEATING OR SMOKE. BUT NOTHING. I HAVE ALREADY REPLACED PCM, TRANSMISSION, AND TORQUE CONVERTER. CONSEQUENTLY MY SHIFTER IS BROKEN AND YOU CAN SEE DOWN INTO TRANSMISSION. OBVIOUSLY NO I CAN'T DRIVE, I WILL HAVE TO HAVE VEHICLE TOWED. WHY HASN'T TRANSMISSION BEEN RECALLED ON THIS VEHICLE. I COULD NOT THINK ABOUT IF MY CHILD WOULD HAVE BEEN WITH ME AND STOOD IN FRONT OF CAR. HE NEVER WOULD HAVE BEEN ABLE TO MOVE THAT QUICKLY OR EVEN WORSE WITH FREEWAY DRIVING I EVEN COULD HAVE BEEN HIT FROM BEHIND.

MY WIFE AND I WERE DRIVING HOME ON THE INTERSTATE. WE HAD JUST MERGED TO THE PASSING LANE TO ALLOW TRAFFIC MERGING FROM AN ON RAMP TO ENTER THE INTERSTATE A VEHICLE NEXT TO US WAS DOING THE EXACT SPEED AS WE WERE WHICH WAS 72 MPH SET CRUISE CONTROL. I HAD VEHICLES APPROACHING FROM THE REAR AND SINCE I WAS IN THE PASSING LANE DECIDED TO SPEED UP AND GET IN FRONT OF THE CAR BESIDE US I PUSHED THE ACCELERATOR ON OUR 08 MERCURY MARINER WITH A 3.0L ENGINE TO THE FLOOR AND THE CAR ACCELERATED IN FRONT OF THE OTHER CAR, WHEN I LIFTED MY FOOT OFF THE ACCELERATOR THE CAR CONTINUED TO ACCELERATE. I PUSHED ON THE BRAKE ONCE WITH NOTHING CHANGING THE CAR CONTINUED TO ACCELERATE. I PROCEEDED TO PUMP THE BRAKE THREE ADDITIONAL TIMES IN ABOUT 1 SECOND INTERVALS. FINALLY THE ACCELERATOR PEDAL RELEASE AND THE CAR SLOWED DOWN. WE PRECEDED HOME WITHOUT FURTHER INCIDENT. THIS IS A VERY DANGEROUS CONDITION AND HAS RESULTED IN SERIOUS INJURIES AND DEATHS IN EARLIER MODEL YEARS OF FORD ESCAPE, MERCURY MARINER AND MAZDA TRIBUTE VEHICLES. I HAVE HAD FORD VEHICLES MY WHOLE LIFE AND HAVE BEEN WORKING ON VEHICLES FOR MORE THAN THIRTY FIVE YEARS. THIS IS NOT NORMAL AND IS NOT THE ONLY TIME OR VEHICLE THIS HAS HAPPENED TO IN THIS YEAR THERE ARE MANY OTHER SIMILAR PEOPLE THAT HAVE SIMILAR COMPLAINTS ON THESE FORD AND MERCURY SUV'S ON THE INTERNET EX: CARCOMPLAINTS.COM TO NAME JUST ONE. THE INTERNET IS FILLED WITH THESE DANGEROUS COMPLAINTS. WHEN ARE YOU GOING TO LIVE UP TO YOUR NAME AND PUT THE SAFETY ASPECT FIRST,WHEN DEALING WITH THESE TO RICH TO BE BOTHERED BY RECALLS AUTO MANUFACTURERS?

SAME RESULTS OF THE CONSUMER SATISFACTION PROGRAM 13N03. A DEFECTIVE THROTTLE BODY. CAR BEGAN TO STALL/CHOKE OUT WHILE ACCELERATING. IT CONTINUED TO DO SO UNTIL IT FINALLY LEFT ME ON THE SIDE OF THE ROAD. FORD IS AWARE OF THE PROBLEM BUT BECAUSE MY CAR WAS BUILT AT A DIFFERENT TIME/PLANT DOES NOT OFFER ASSISTANCE FOR A KNOWN UNSAFE PROBLEM. THIS STARTED ON THE FREEWAY AND CONTINUED AFTER I EXITED FOR FEAR OF STALLING ON THE FREEWAY. CAR HAS TO BE TOWED/REPAIRED AT MY EXPENSE. A FRIEND HAS THE SAME MODEL VEHICLE/SAME PROBLEM LAST YEAR, BUT DUE TO HER CAR BEING BUILT AT THAT PLANT/TIME WAS COMPENSATED FOR THE SAME EXACT PROBLEM. AGAIN, FORD IS AWARE OF THE PROBLEM BUT MINIMIZES COVERAGE. I CAN'T HELP BUT THINK OF WHAT COULD HAVE HAPPENED IF MY WIFE/DAUGHTER HAD BEEN DRIVING(AT NIGHT). IN REALITY, IT IS UNSAFE AND I COULD HAVE BEEN KILLED.
