“Over the course of several months the engine seemed to rev up while the brakes were applied for a stop. On july 29,2013 I took the car to a reliable service center and asked for an analysis of what the cause could be. Analysis result indicated that the throttle body assembly was the problem. A new assembly was installed, and I was informed that ford has a bulletin on that particular part on 2006 Grand Marquis. The mechanic felt that a recall should be issued for safety reasons.”
NHTSA complaint #10534103, filed 2013-08, 29,802 miles“When parking a newly acquired used 2006 Mercury Grand Marquis at idle speed in a local shopping center, the engine accelerated and the harder I pressed the brake the faster the engine ran. To the extent the traction control activated and the wheels spun in place. The only way I prevented crashing into three parked was to shift the transmission into neutral with the engine racing. What apparently happened was my foot was not centered on the brake pedal and the pedal traveled to the point where I was also pressing on the accelerator. …”

NHTSA complaint #11048819, filed 2017-11“When applying the brakes, unwanted acceleration occurred causing the car to lunge forward. The manager of the repair department took a ride with me to see if my foot hit both the brake and the gas pedal. He acknowledged it was physically impossible. The repair dept. Could not find the cause of the problem. Nothing was done to correct the problem. It has happened again (5th time) when I had two of my grandchildren with me! I have another appointment with the dealership.”
