2005 Mercury Grand Marquis brakes problems

Filed Sep 12, 2025 · Brakes · FL

My wife has a 2005 Mercury Grand Marquis. This vehicle has what I believe is an extremely unsafe placement of the brake and accelerator pedals. The pedals are extremely close together, closer than I have ever seen on any other vehicle. My wife has depressed the accelerator while pressing the brake pedal on more than one occasion. We went recently for an oil change. The technician pressed the accelerator while pressing the brake pedal while putting the vehicle into reverse. The vehicle lunged into the parking lot. Fortunately, there were no vehicles behind my vehicle. If the technician had been shifting from neutral into drive, he would have driven into the building. The technician said that he has had similar experiences with Ford vehicles and that one of his relatives has a Ford and that this is a frequent experience with that vehicle. I am a disabled Veteran with a below knee amputation of the right leg. I have had no problem driving vehicles before this one. I have stopped driving this vehicle because I believe it is a crash waiting to happen. I have asked numerous people to sit in the vehicle and see if they feel that the pedals are too close together. To date, all have said that they feel that the pedals are too close together and that they would not drive the vehicle in question because they also feel that this vehicle and no doubt other Ford vehicles with this pedal arrangement are crashes waiting to happen. I request that the federal safety agency look into the pedal arrangement of this vehicle and all Ford vehicles as I believe this arrangement is a safety hazard that is on the highways of America and may have contributed or directly caused numerous crashes since at least 2005.

Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6) [xxx] 4/21/2010 2005 mercury marquis on april 17th 2010, at approximately 1 pm, as I hit the brakes approaching a stop sign, the brake failed and the engine raced, we traveled about 14 feet through the stop sign, the brakes worked again and the engine died down. Had there been a car in front of me or a pedestrian crossing I would have hit them. We took the car to a local shop on the same day, they diagnosed it and couldn't find anything wrong with it. On the 19th we took the car to a lincoln mercury dealer who also did not find anything wrong with the car. They had no suggestions for solving this dangerous condition. About 10 days ago I had the same thing occur, however, it was no more then 1 or 2 seconds and I was on the highway. Researching on the internet I found a number of cases of this serious problem with the mercury and some other ford products. This is very serious and must be remedied.

Both front inner brakes not properly contacting rotor. Only a 1 inch width of inner brake pads have ever contacted rotor. Based upon the amount of rust and pitting of the non contact area of the rotors it appears that the brake pads were never contacting properly. In all my years of servicing vehicles I have never seen this type of defect before.
