2010 Mercury Mariner vehicle speed control problems

“WHEN INTERING TO TUNNEL MY CAR SUDDENLY SPEED UP IT FELT LIKE I HAD THE GAS PEDLE DOWN TO THE FLOOR. EVEN WHILE HOLDING THE BRAKE ALL THE WAY DOWN, THIS DID NOT SLOW THE CAR DOWN MUCH. THERE WERE NO WARNING LIGHTS OR CHECK ENGINE LIGHTS ON THEN OR NOW”

“ELECTRONIC THROTTLE BODY P2119 CODE. ALL OF THE SUDDEN LOSSES POWER GOING INTO OR OUT OF TRAFFIC AND THE WRENCH TOOL LIGHT "LIGHTS UP" IT MAY GO AWAY BY ITSELF OR NOT , "CUT BE SCARY" AT TIMES IT HAS SHUT DOWN IN SEVERAL INSTANCES ON MY OWN ST OR DOWN THE AVE OR ANOTHER TOWN ETC... FOR NO APPARENT REASON IT HAPPENS WHILE TURNING OR DURING ACCELERATION AT ONE POINT I HAD TO WAIT FOR SEVERAL MINUTES ON THE HIGHWAY BEFORE STARTING THE VEHICLE AGAIN AND I GET SIMILAR CODES RELATED TO TBS POWERTRAIN AND THE FUEL CAP I NOTICED THAT WHEN FILLING UP, I NEED TO STOP PUMPING GAS ONCE IT HAS STOPS AUTOMATICALLY, WITHOUT ME TOPPING IT OFF NOT EVEN ONCE! AND THE LIGHT WILL MOST LIKELY WILL NOT COME ON,IT MAY GO AWAY BY ITSELF IF NOT I ERASE THE CODE.I CLEAN THE ELECTRONIC THROTTLE BODY LAST SUMMER AND IT HAS RUN WITH NO PROBLEMS AT ALL UNTIL NOW! WELL A MONTH A GO! THIS SUMMER I AM GETTING LOTS OF PROBLEMS WITH THE TBS AGAIN SAME SYMPTOMS LIKE BEFORE ALL OVER AGAIN,EXCEPT FOR THE GAS LIGHT. THANK YOU”

“WAS STOPPED AT A RED LIGHT, CAR HAD BEEN DRIVING FINE, BUT WHEN THE LIGHT TURNED GREEN AND I PROCEEDED MY CAR SUDDENLY HAD REDUCED POWER AND WOULD NOT DRIVE MORE THAN 40-45 MPH. NO LIGHTS OR ANYTHING CAME ON THE DASH THE FIRST TIME. THE SECOND TIME HOWEVER A YELLOW/ORANGE WRENCH LIGHT APPEARED. I GOT HOME AND PARKED FOR THE REMAINDER OF THE DAY BUT THEN THE FOLLOWING DAY THE PROBLEM STILL PROCEEDED AND I THEN LET IT SIT ALL WEEKEND. THE FOLLOWING MONDAY I TURNED IT ON TO TAKE TO THE REPAIR SHOP AND THE CAR DROVE FINE THAT ENTIRE DAY. THE NEXT DAY, TUESDAY, WHILE DRIVING HOME FROM WORK IT HAPPENED AGAIN ONLY I COULDNT GO FASTER THAN 30MPH IN A 55 MPH ZONE. CAR WAS TAKEN BACK TO SHOP AND DIAGNOSED AS A FAILURE IN THE THROTTLE BODY. DURING THIS TIME OF REDUCED POWER FANS IN THE TRUNK SPACE GOT EXTREMELY LOUD AND BEGAN SUCKING IN AIR, AS IF TRYING TO COOL THE BATTERIES. NEEDLESS TO SAY FORD HAS BEEN NO HELP AND I CAN NOT GET TO WORK AS I CANNOT SAFELY DRIVE MY VEHICLE DUE TO THE LIMP HOME MODE ACTIVATING AND RANDOM TIMES. THE PRIOR INVESTIGATION INFURIATES ME TO SEE THEY EXTENDED A WATTANTY INSTEAD OF DOING RECALL BECAUSE NOW OWNERS LIKE MYSELF ARE STUCK NOT EVEN…”

“VEHICLE SURGES WILDLY AT IDLE SPEEDS IN TRAFFIC. VEHICLE STALLS OUT WHILE DRIVING REGULAR HIGHWAY SPEED, SURGES WILDLY WHILE DRIVING, RPM SPIKES DRASTICALLY WHILE DRIVING AND AT IDLE. STALLS AND SURGES BOTH WHILE ENTERING TRAFFIC FROM A STOPPED POSITION AND WHILE DRIVING AT REGULAR PACE. STRUGGLES TO CRANK AFTER FUELING THE VEHICLE. SPITS AND SPUTTER AND SHAKES WHILE AT IDLE....UPDATED10/20/15 *BF”

“DRIVING FROM COLUMBUS TO CINCINNATI AROUND 1:00 AM WITH MY DAUGHTER, SON AND 15 MONTH OLD GRANDDAUGHTER. THE CAR LOST ALL POWER LEAVING US STRANDED ON THE SIDE OF THE ROAD. AS I PULLED OVER THE CAR BEGAN TO SHAKE, ALMOST LIKE THERE WAS WATER IN THE GAS LINE. I TURNED THE CAR OFF, WAITED A FEW MINUTES AND THEN RESTARTED. THE CAR RESET ITSELF AND LUCKILY WE MADE IT THE REST OF THE WAY HOME. NOT TOO LONG AFTER THAT, I WAS DRIVING HOME FROM WORK AND IT DID THE SAME THING. EXCEPT THIS TIME, IT WOULD ONLY GO ABOUT 2 MILES BEFORE IT WOULD QUIT AGAIN. THIS IS A VERY DANGEROUS ISSUE. NO ONLY COULD I HAVE BEEN IN AN ACCIDENT, BUT BEING STRANDED ON THE SIDE OF THE EXPRESSWAY IN THE MIDDLE OF THE NIGHT WITH AN INFANT WAS TERRIFYING! I HAD THE THROTTLE VALVE SENSOR REPLACED AND THERE HAS NOT BEEN ANY ADDITIONAL INSTANCES OF POWER FAILURE.”

“ON THAT DATE, I WAS DRIVING HOME WITH MY WIFE AT APPROXIMATELY 2 PM. SUDDENLY, THE CAR WENT OFF AND THE STEERING WHEEL WENT STIFF. AS I TRIED TO MOVE UNSUCCESSFULLY, WE WENT DOWN TO A SLOPE OF ABOUT 20 DEGREES. AS A RESULT, BOTH OF US HAD TO BE TAKEN FOR EMERGENCY TREATMENT FOR KNOCKS, CUTS AND FOLLOW UP CHECKS. SO FAR, IT HAS COST US $16,497.00 AND REPAIR OF THE CAR US$6,853.00. THERE HAS BEEN OTHER EVENTS WHERE THE CAR SUDDENLY STOPS AND THE STEERING WHEEL BECOMES STIFF. BUT, I DON T USE THE CAR IN THE HIGHWAY BUT ONLY FOR SHORTS ERRANDS AND WITHIN THE AREA WHERE WE LIVE. ITS BEEN A NIGHTMARE. I HAVE CHANGED THE THROTTLE CASING MODULE, THE RESTRAINT CONTROL MODULE, I PUT A RUBBER STOP ON THE ACCELERATION PEDAL, ETC. AGAIN, OUT OF THE ACCIDENT IT HAS BEEN OVER 4 THOUSAND DOLLARS IN TRYING TO FIX THE CAR. *TR”
