2006 Mercury Montego Fuel system Problems

Owner-reported complaints naming the fuel system system, filed with NHTSA

Data refreshed

Fuel system reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The throttle body on the 2006 Mercury Montego SHOULD HAVE been recalled just like the 2007 Mercury Montego that I owned previously was recalled. It has the SAME EXACT problem! The throttle is VERY DANGEROUS as it dumps fuel without me touching the gas pedal. I have already almost killed a pedestrian! Please help! I cannot afford to fix the car and I don't want to hurt anyone. Thank You , [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

AFTER THE ENGINE WARMS UP, UPON ACCELERATION AND THE AUTOMATIC TRANSMISSION IS SHIFTING GEARS FROM 1 TO 2, 2 TO 3 AND 3 TO 4 THERE IS A STUTTERING AND OFTEN A JERKING WHEN THE AUTOMATIC TRANSMISSION IS SHIFTING. THIS JERKING ALSO OCCURS UPON SLOW BRAKING WHEN THE TRANSMISSION IS DOWN-SHIFTING FROM GEARS 4 TO 3 TO 2 TO 1. IT'S GETTING WORSE!! *TR

WHEN SHIFTING OUT OF PARK OR NEUTRAL, OR FROM DRIVE TO REVERSE (OR REVERSE TO DRIVE), THE CAR LURCHES FORWARD OR BACK WITH NO WARNING. THIS CAN BE A HAZARD, IF NEAR PEDESTRIANS OR IF PARKED IN A TIGHT SPACE. ADDITIONALLY, IF THIS OCCURS SEVERAL TIMES,(EG:PARKING) THE CAR WILL STALL & THE REPAIR "WRENCH" ON THE DASHBOARD LIGHTS UP. THE CAR MUST BE TURNED OFF FOR ABOUT 1 MINUTE & RE-STARTED TO GET BACK TO NORMAL. THIS UNFORTUNATELY IS TOO COMMON OCCURRENCE. IS FORD WAITING FOR A FATALITY BEFORE TAKING STEPS FOR CORRECTIVE ACTION. *TR

CLIP HOLDING FUEL FILTER HOSE TO THE FUEL FILTER FAILED ALLOWING THE HOSE TO COME LOOSE AND LEAK FUEL UNDER PRESSURE. THE CAR HAD ONLY BEEN DRIVEN 4 BLOCKS SO THE EXHAUST SYSTEM WAS STILL COOL. HAD THE EXHAUST SYSTEM BEEN HOT AND THE FAILURE OCCURRED AT HIGH SPEED A FIRE WOULD MOST LIKELY HAVE OCCURRED. THE FUEL FILTER HAD NOT BEEN CHANGED, AS CONFIRMED BY MY SERVICE RECORDS, MAKING IT THE FILTER INSTALLED AT THE FACTORY. *TR
